AT:rs cc: Department Heads Pamela McCarthy, City Clerk Trudy Slater, Administrative Analyst MEMORANDUM ~¢-~~ July 17, 1998 TO: Alan Tandy, City Manager FROM: Gene Bogart, Water Resour~s ~Aanager SUBJECT: ENVIRONMENTAL IMPACT REPORT Attached please find the just-completed draft Environmental Impact Report for the NORTHEAST BAKERSFIELD BIKE PATH and WATER FACILITIES PROJECT. As you know, this project will provide a new source of high-quality Kern River water to City residents, and at the same time provide a new extension of the bike path to the Kern River. When completed, residents will be able to use the new Morning Drive bike path described in this project to gain direct access to Hart Memorial Park, the Kern County Soccer complex and the California Living Museum (C.A.L.M.) facilities located north of Alfred Harrell Highway along the Kern River. In addition to the new bike path, the water facilities to be constructed with this project include a permanent intake structure from the Kern River; approximately 20 acres of reservoir ponds; two pump stations; pipelines and a new water filtration plant. Together, these facilities will provide a new source of high quality City water to the northeast and augment water supplies currently being used throughout the City. This project will result in reduced groundwater pumping in the existing downtown and south - central areas of the City, which will preserve the groundwater "in place" for future use during critically dry periods - A true conjunctive use program for the City of Bakersfield. I'd like to thank all City departments for participating in this complex and exciting project, including Raul Rojas and the Public Works Department; Jack Hardisty and his Planning staff; Greg Klimko's property management group and the Manager's office for keeping this project on track and on time. The date of this memo reflects the beginning of the 45-day review period for this E.I.R. GB:s; Attachment BAKERSFIELD Development Services Department Jack Hardisty, Director Dennis C.

Grady Building Director Planning Director (805) 326-3720 Fax (805) 325-0266 (805) 326-3733 Fax (805) 327-0646 NOTICE OF AVAILABILITY OF A DRAFT ENVIRONMENTAL IMPACT REPORT (DEIR) PUBLIC HEARING BEFORE THE PLANNING COMMISSION OF THE CITY OF BAKERSFIELD NOTICE IS HEREBY GIVEN that the City of Bakersfield has completed the Draft Environmental Impact Report (DEIR) for the Northeast Bakersfield Bike Path and Water Facilities project. The DEIR discusses the potential environmental effects attributable to this project which is generally described and located as follows: Bike Path Construction: The proposed project includes the construction of a 3.7 mile Class I bike path segment and water facilities in the northeast portion of Bakersfield. The proposed water facilities include a water treatment plant and access road, raw water pipelines, potable water pipelines, reservoir (ponds), pump stations, and intake structure. The portion of the project site that is located south of Alfred Harrell Highway is located in the City of Bakersfield and the portion of the site that is located north of Alfred Harrell Highway is located in the County of Kern. The bike path portion of the project consists of a linear site extending from the future intersection of Alfred Harrell Highway and Morning Drive southerly along the current unimproved alignment of Morning Drive to Paladino Drive, then westerly to Fairfax Road. Water Facilities Develooment: The water treatment plant Portion of the project will be located on a 40-acre site located 0.5 mile north of Paladino Drive and 0.5 mile east of the current Morning Drive and the proposed bike path alignment. The treatment plant is initially proposed to process 10 million gallons per day (mgd), and then to be expanded (in stages) to a maximum of 60 mgd. Construction of a 20-foot wide access road extending from the existing paved portion of Paladino Road, westedy to the proposed bike path, then northerly along the bike path for 0.7 mile, and then easterly to the treatment plant site is also proposed. The water facilities will also include a water diversion facility and Iow lift pump station at the edge of the Kern River north of the existing California Living Museum (CALM) facilities, a 15-acre raw water reservoir west of the CALM facilities, north of Alfred Harrell Highway, and east of the existing County bike path alignment. A gravity-flow water pipeline will extend from the reservoir for a distance of 0.9 mile westerly along the north boundary of the Soccer Park to the existing Hart Memodal Park unlined channel. The proposed conveyance pipeline (to be constructed by the County of Kern) will replace an existing rock and boulder diversion structure in the Kern River that presently feeds river water to the Hart Memodal Park unlined channel. The project also includes a high lift pump station adjacent to the proposed reservoir, capable of transmitting the raw water supply to the water treatment plant. The water supply will be conveyed by means of a pipeline which will extend alongside the new bike path alignment for approximately 0.7 mile, and then extend east to the water treatment plant. A new potable water pipeline will extend from the proposed plant to the bike path, then branch to the north along the bike path to an existing potable water line located just north of the proposed Hart Memorial Park conveyance. The water pipeline will provide potable water to existing recreation uses as well as future surrounding development. A southerly branch potable water pipeline will extend southerly from the treatment plant along the bike path to Paladino Drive, then extend west along Paladino Road adjacent to the bike path to the northerly terminus of the existing improved portion of Morning Drive. The i~='-~.line will then extend south along Morning Drive to connect with an existing water supply pipeline along Panorama Drive.

EtR. aoc iii Table of Contents Existing Hart Memorial Park intake canal and bike path SECTION I INTRODUCTION Northeast BakersfieM Bike Path and Water Facilities - Draft EIR SECTION I INTRODUCTION 1.1 PURPOSE OF THE EIR This draft environmental impact statement (EIR) has been prepared to evaluate the potential environmental impacts associated with the construction and operation of the proposed Northeast Bakersfield Bike Path and .Water Facilities project. The City of Bakersfield is the lead agency for the preparation of the EIR. This document is a program EIR and has been prepared in conformance with the California Environmental Quality Act (CEQA), California Public Resources Code Section 2100 et seq; the California CEQA Guidelines (California Code of Regulations, Title 14, Section 15000 et seq.); and the rules, regulations, and procedures for implementing CEQA as adopted by the City of Bakersfield. This draft EIR is intended to serve as an informational document for public agency decision-makers and the general public regarding the objectives and components of the proposed project. This document will address the potentially significant adverse environmental impacts that may be associated with the planning, construction, and operation of the project, as well as identify appropriate feasible and alternatives that be to reduce eliminate these mitigation adopted impacts. measures may or This EIR considers a series of actions that are needed to achieve development of the proposed project. The actions currently being requested include approval of the project components, and a General Plan Land Use Element amendment to redesignate the proposed water treatment plant site from Low Density Residential to Public Facility. Additional City approvals will be needed. In addition to the City, public agencies (i.e., cooperating, responsible, trustee agencies) will also use the other and information in this EIR in their decision making or permitting process as well as additional information that may be presented during the CEQA process. These agencies and their anticipated responsibilities are outlined in Section III.4 of this document. The approvals required for project implementation include the following: · Certification and Approval of Final EIR · Easements · General Plan Amendment · NPDES Permit · Conditional Use Permit · Streambed Alteration Agreement · Plans and Specifications · Reclamation Board Permit · Grading Permits · USACE Clean Water Act Permit · Building Permits Th/s EIR is the primary reference document in the formulation and implementation of a mitigation monitoring program for the proposed project. Environmental impacts are not always mitigable to a 02160007.EIR. doc [- l Introductt'on Northeast Bakersfield Bike Path and Water Facilities - Draft EIR level considered less than significant. In such cases, impacts are considered significant unavoidable impacts. In accordance with Section 15093(b) of the state CEQA Guidelines, if a lead agency approves a project that has significant impacts that are not substantially mitigated (i.e., significant unavoidable impacts), the agency shall state in writing the specific reasons for approving the project, based on the final CEQA document and any other information in the public record for the project. This is termed, per Section 15093 of the state CEQA Guidelines, a "statement of overriding considerations." The intent of this program EIR is to provide a comprehensive single environmental document that will allow the City of Bakersfield to carry out the proposed project. This EIR provides a reasonably anticipated scope of the project. This EIR will also be used to determine whether subsequent environmental documentation will be required. This document analyzes the environmental effects of the project to the degree of specificity appropriate to the current proposed actions, as required by Section 15146 of the state CEQA Guidelines, as well. This analysis considers the series of actions associated with the various discretionary actions required for project implementation to determine the associated short-term and long-term effects. This EIR discusses both the direct and indirect impacts of this project, as well as the cumulative impacts associated with other past, present, and reasonably foreseeable future projects. CEQA requires the preparation of an objective, full disclosure document, to inform agency decision makers and the general public of the direct and indirect environmental effects of the proposed action; provide mitigation measures to reduce or eliminate potential adverse effects; and identify and evaluate reasonable alternatives to the proposed project. 1.2 EIR FOCUS AND EFFECTS FOUND NOT TO BE SIGNIFICANT This EIR addresses the potential environmental effects of the proposed project. The scope of the EIR includes issues identified by the City of Bakersfield during the preparation of the Initial Study (IS) and Notice of Preparation (NOP) for the proposed project, as well as environmental issues raised by agencies and the general public in response to the IS and NOP that was distributed for a 30-day review beginmng on June 5, 1998. The IS and NOP and the comment letters received during the NOP public review period are included in Appendix A of this ElK Following are the issues addressed in this EIR. · Water Resources · Cultural Resources · Biological Resources · Aesthetics · Land Use Plans and Policies · Public Health and Safety · Air Quality (Short-term) · Growth Inducement · Noise (Short-term) 02160007. £IR. doc 1-2 Introduction Northeast BakersfieM Bike Path and Water Facilities - Draft EIR The environmental issues that were determined not to be significantly affected by the proposed project and, therefore, do not require evaluation in the document, per Section 15063(c) of the State CEQA Guidelines (as amended): · Earth Resources · Utilities · Transportation/Circulation · Population · Air Quality (Long-term) · Housing · Noise (Long-term) · Energy · Public Services The following is intended to supplement the information in the IS/NOP. · Earth Resources - A preliminary geotechnical investigation was conducted for the proposed water treatment plant site by Soils Engineering, Inc. in June 1998. The maximum credible and maximum probable repeatable-high-ground accelerations that can be expected at the proposed water treatment plant site are 0.3 lg and 0.1 lg, respectively from the Kern Front fault system. These potential accelerations are not exPected to significantly affect the water treatment facilities. Implementation of the proposed project will also allow the Hart Memorial Park rock and boulder diversion dam within the Kem River to wash away. The County of Kem has periodically rebuilt the diversion dam to maintain the diversion of Kern River water into the County's unlined channel. The presence of the diversion dam has resulted in erosion of the north bank of the Kern River. Eliminating the need for the existing diversion dam would reduce the erosion hazard along the north bank of the river. Due to the existing topography, a levee will be developed to create the raw water pond. Soil that is excavated from the pond area is expected to be used to create a levee. The northwest to northeast side of the levee will have a height of approximately 2 to 12 feet with the highest portion of the levee facing the Kem County Soccer Park and the Kem River. The southwest to southeast side of the levee will have a height of approximately 2 to 4 feet. The southwest to southeast side of the levee will be gradually sloped to the edge of the pond. No significant impacts are anticipated with the movement of soil for construction of the levee. · Traffic Hazards - The project site between Alfred Harrell Highway and Paladino Drive is currently used by unauthorized off-road vehicles such as motorcycles. The implementation of the proposed bike path as well as the proposed access road to the water treatment plant site may increase the use of unauthorized off-road vehicles in the project area. To reduce the project's contribution to the existing impact, the following measure shall be implemented. · Prior to approval of the plans and specifications for the bike path, the City shall include design measures (i.e., posts and fencing) to prevent unauthorized vehicles to use the bike path. 02160007.EIR. doc I-3 Introduction Northeast BakersfieM Bike Path and Water Facilities - Draft EIR · Prior to approval of grading permits for the water treatment plant access road, design measures (i.e., fencing) to prevent unauthorized vehicles from entering the access road north of Morningside Court. · Vector Control - Implementation of the raw water pond will include landscaping on the perimeter of the pond; however, no vegetation will be planted on the banks of the ponds so that the potential mosquito population in the pond area is kept to a minimum. With the elimination of vegetation along the banks of the pond, no significant vector impacts are expected to occur. · Odor - Based on discussions with City staff and staff at the San Joaquin Valley Unified Air Pollution Control District, water treatment facilities are not known to emit adverse odors. No significant odor impacts would occur with the implementation of the proposed water treatment plant. Agencies, organizations, and interested parties not contacted or who did not respond to the request for comments about the project during the preparation of the draft EIR currently have the opportunity to comment during the 45-day public review period on the draft EIR. 1.3 PROJECT SPONSORS AND CONTACT PERSONS The City of Bakersfield is the lead agency for the preparation of this EIR. Michael Brandman Associates is the environmental consultant to the City for the project. There are three project proponents who will be constructing and operating components of the project. The City of Bakersfield will be constructing and operating the intake structure, low lift station, pond, and bike path. The California Water Services Company will construct and operate the high lift station, raw water pipeline, potable water pipeline, and water treatment plant. The County of Kern Parks Department will construct and operate the Hart Memorial Park conveyance pipeline.

The portion of the project site that is located south of Alfred Harrell Highway is located in the City of Bakersfield and the portion of the site that is located north of Alfred Harrell Highway is located in the County of Kern. The proposed project consists of a bike path and water facilities. The water facilities include a river diversion (intake structure), Iow lift pump station, raw water pond, Hart Memorial Park conveyance pipeline, high lift pump station, water treatment plant, water pipelines, and an access road. As proposed, the bike path portion of the project encompasses a linear site that is located south of the Kern River and extends from the future intersection of Alfred Harrell Highway and Moming Drive southerly to Paladino Drive, then westerly to Fairfax Road, The water facility portion of the project extends from the Kern River adjacent to the California Living Museum (CALM) to the vicinity of the Alfred Harrell Highway and Morning Drive, and includes a gravity-flow water pipeline extending approximately 0.9 miles to the west between the eastern boundary of the existing Kern County Soccer Park and Hart Memorial Park. The future bike path and raw water transmission pipeline will share the current adopted alignment of Morning Drive between Alfred Harrell Highway and the water treatment plant where it will turn east toward the facility. From the water treatment plant, a potable water pipeline will extend west to the bike path and the adopted alignment of Morning Drive. At the bike path, a potable water pipeline will extend north along the bike path and along the west side of the proposed pond and existing County bike path. The pipeline would connect to an existing potable water line that is located just north of the proposed Hart Memorial Park conveyance pipeline. At the bike path, a potable water pipeline will also extend south to Paladino Drive. At Paladino Drive, the potable water pipeline will extend to the west to Morning Drive and then south 0.7 mile. The water treatment plant portion of the project site is located approximately 0.5 mile north of Paladino Drive and 0.5 mile east of the new bike path alignment. An access road is proposed to provide vehicle access to the water treatment pl~ }' site. The new access road will extend from the existing paved portion of Paladino Drive (approximately 0.2 mile east of the bike path alignment) to the bike path alignment. The access road will extend approximately 0.7 mile north of Paladino Drive along the bike path alignment then east approximately 0.3 mile along the water pipelines to and from the water treatment plant. The proposed water treatment plant will require a General Plan Land Use Element amendment from Low Density Residential to Public Facility. 02160007.EIR. doc II- 1 Executive Summary Northeast BakersfieM B~ke Path and Water Facilities - Draft EIR 11.2 AREAS OF CONTROVERSY/ISSUES TO BE RESOLVED During the preparation of the Drai~ EIR, no areas of controversy or issues to be resolved were raised by the lead agency, other agencies, or the public. 11.3 SUMMARY OF ALTERNATIVES In accordance with Section 15126(d)(2) of the CEQA, Section VIII of this EIR includes a comparative evaluation of the proposed project with alternatives to the project. Additionally, the alternatives were discussed in terms of achieving the project objectives. This EIR includes an evaluation of the £ollowing alternatives to the proposed project: · No Project Alternative - The proposed bike path and water facilities would not be developed under this alternative. · Alternative Site A - This alternative would include the same location of the bike path and a majority of the water facilities. The water treatment plant would be located north of and adjacent to Paladino Drive between the north to south alignment of the bike path and the existing terminus of Morning Drive at Paladmo Drive. · Alternative Site B - This alternative would include the same location of the bike path and a majority of the water facilities. The water treatment plant would be on a plateau approximately 3,000 feet west of the proposed water treatment plant. · Alternative Site C - This alternative would include the same location of the bike path and the water facilities north of Alfred Harrell Highway. All of the water facilities south of Alfred Harrell Highway would not be in the same location under the proposed project. The water treatment plant would be located on a plateau approximately 1.1 miles northwest of the proposed water treatment plant. The raw water pipeline that would extend between the high lilt station and the water treatment plant would extend south of Alfred Harrell Highway into the ravine and then traverse approximately 0.7 mile along a west to east drainage channel to the water treatment plant site. The potable water pipeline would extend west from the treatment plant site to the existing north to south Pacific Gas and Electric utility con'idor. The water pipeline would extend along the corridor to Panorama Drive. Section VIII of this EIR provides detailed descriptions and analysis of each alternative. The Environmentally Superior Alternative was determined to be the proposed project. The No Project (No Action) alternative would result in less environmental impacts; however, this alternative would not achieve the objectives of the project.

A mitigation monitoring program, incorporating the mitigation measures set forth in this document, will .ii be adopted at the time of certification of the EIR. II.5 SUMMARY OF ENVIRONMENTAL EFFECTS AND MITIGATION MEASURES Sections V and VI describe in detail the environmental impacts that would result from the implementation of the proposed project. Table II-1 summarizes impacts of the proposed project and mitigation measures for these impacts. Impacts that are noted in the summary as "significant" after mitigation will require the adoption of a statement of overriding considerations, if the project is approved as proposed (CEQA Section 21081). Impacts of the project are classified as (1) NS, not significant (adverse effects that are not substantial according to CEQA, but may include mitigation); (2) S, significant (substantial adverse changes in the environment); (3) PS, potentially significant (potential substantial adverse changes in the environment); (4) B, beneficial.

The portion of the project site that is located south of Alfred Harrell Highway is located in the City of Bakersfield and the portion of the site that is located north of Alfred Harrell Highway is located in the County of Kern. As proposed, the bike path portion of the project encompasses a linear site that is located south of the Kern River and extends from the future intersection of Alfred Harrell Highway and Morning Drive southerly to Paladino Drive, then westerly to Fairfax Road. The water facility portion of the project extends from the Kern River adjacent to the California Living Museum (CALM) to the vicinity of the Alfred Harrell Highway and Morning Drive, and includes a gravity-flow water pipeline extending approximately 0.9 mile to the west between the eastern boundary of the existing Kern County Soccer Park and Hart Memorial Park. The future bike path and water transmission pipeline will share the current adopted alignment of Morning Drive between Alfred Harrell Highway and Paladino Drive. A new water pipeline will also extend north along the bike path and along the west side of the proposed pond and existing County bike path. The pipeline would connect to an existing potable water line that is located just north of the proposed gravity-flow pipeline. At Paladino Drive, a new pipeline will also extend to the west to Morning Drive and the south approximately 0.6 mile and connect to the existing water facilities located at the intersection of Panorama Drive and Morning Drive. The water treatment plant portion of the project site is located approximately 0.5 mile north of Paladino Drive and 0.5 mile east of the new bike path alignment. An access road is proposed to provide vehicle access to the water treatment plant site. The new access road will extend from the existing paved portion of Paladino Drive (approximately 0.2 mile east of the bike path alignment) to the bike path alignment. The access road will extend approximately 0.7 mile north of Paladino Drive along the bike path alignment then east 0.3 mile along the water pipelines to and from the water treatment plant (see Exhibit III. 1-2). III.2 PROJECT CHARACTERISTICS The proposed project includes the construction of a bike path and water facilities (water treatment plant, pipeline, reservoir (pond), pump stations, and intake channel.

At Alfred Harrell Highway, the bike path is proposed to extend east along the highway to a proposed bike at-grade crossing on Alfred Harrcll Highway'and connect to the existing County bike path at the CALM facility. Bicyclists travelling from Hart Memorial Park to Fail-fax Road would travel along the County bike path to the CALM facility and connect with Alfred Harrell Highway. At Alfred Harrell Highway, the bike path would extend west along the highway to a proposed bike at-grade crossing on Alfred Harrell Highway and connect to the proposed bike path south of Alfred Harrell Highway. Bike crossing signs are proposed along Alfred Harrell Highway to alert motorists and bicyclists of the crossings. Marked bike crossings are proposed to extend across the highway (one at the CALM facility and one approximately 0.4 mile west of CALM). The bike path will primarily follow the future alignments of Paladino Drive and Morning Drive. The bike path will consist of a 12-foot-wide asphalt concrete section with a delineated bike lane centerline and graded shoulders. WATER FACILITIES The proposed project also includes a number of water facilities to serve an area in northeast Bakersfield that is not currently served by a water district. The water facilities include the diversion of water from the Kern River to a proposed water treatment plant located east of Morning Drive, approximately 0.5 mile north of Paladino Drive. A description of each facility is discussed below. Kern River Diversion and Low Lift Pump Station A reinforced concrete intake structure, approximately 30-feet wide by 50 feet long by 15 feet high (partially below grade), will be constructed starting at the edge of the Kern River channel at a location north of the existing CALM facilities. A steel trash screen will be installed across the width of the intake structure to prevent debris from entering the station. The trash screen will include steel pump horizontal bars with an approximately 3 to 4-inch separation between each bar. At the end of the intake structure, a sand removal and ejection system will collect sand from the intake water and return it to the Kern River downstream of the intake structure. The intake water will then flow by gravity through two 200-foot long buried reinforced concrete pipes, approximately 42 inches in diameter each, discharging to a pump station wet well. The wet well will be a below grade reinforced concrete structure approximately 20 feet long by 40 feet wide by 20 feet high, located on the slope near the existing CALM raw water reservoir. The end of the wet well will contain a series of pumps with the ability to pump water at various flow rates, discharging into the reservoir pond. The pump station site will also have a small housing for electrical service, switch gear, and motor controls. 02160007. EIR. doc III-2 Project Description Northeast Bakersfield Bike Path and Water Facilities - Draft EIR Raw Water Pond A new raw water reservoir covering approximately 15 acres of surface area with a capacity of approximately 120 acre-feet will be constructed just south of the Kern River between the existing County bike path to the west, the existing CALM site to the east, and Alfred Harrel Highway to the south. The reservoir will provide a dual purpose: (1) impounding raw water for the water treatment plant, and (2) incorporate the reservoir into CALM's conceptual plan as a water feature. A reservoir pond will be constructed in a free form shape to create a natural appearance. Due to the existing levee will be developed to create the pond. The northwest to northeast side of the levee topography, a will have a height of approximately 2 to 12 feet with the highest portion of the levee facing the Kern County Soccer Park and the Kern River. The southwest to southeast side of the levee will have a height of approximately 2 to 4 feet. The southwest to southeast side of the levee will be gradually sloped to the edge of the pond. A gravel maintenance road would be constructed on top of the levee. The perimeter of the pond and surrounding lands will be landscaped to enhance a natural appearance. No landscaping will be planted on the banks of the pond so that potential mosquito population in the pond is kept to a minimum. A 12-foot wide gravel all-weather access road will: be constructed around the perimeter of the pond and levee. This road will provide access to the :river diversion, pump stations, and Hart Memorial Park turnout. · Hart Memorial Park Turnout and Conveyance Pipeline The existing water source for the lakes within Hart Memorial Park is a rock andboulder diversion dam across the Kern River. The dam diverts water to an unlined canal, which conveys the water from the river to Hart Memorial Park. The existing rock and boulder dam is a physical barrier across the width of the river, except for a short bypass on the northerly side. This physical barrier affects recreational activities (such as floating on the river on ratis). In its current condition, when there is low flow in the river, no water is diverted into the canal. This situation requires pumping with a portable pump to maintain a minimum flow into the canal and to the park lakes. The new diversion and conveyance facilities for Hart Memorial Park would eliminate the need for the rock and boulder diversion structure in the Kern River. A slide gate controlled turnout structure will be installed on the northwest reservoir embankment. This turnout would connect to a pipeline (to be constructed by the County) with a flow meter downstream. The pipeline would mn approximately 0.9 mile from the reservoir to the Hart Memorial Park canal along the northerly boundary of the Kern County Soccer Park. The flow meter structure, located downstream from the turnout, would measure flow with an indicator located at the turnout structure. 02160007.EIR. doc III-3 Project Description Northeast Bakersfield Bike Path and Water Facilities - Draft EIR In addition to the turnout structure that would connect the raw water pond to the Hart Memorial Park conveyance pipeline, an additional turnout structure and pipeline for the Kern County Soccer Park would be constructed immediately adjacent to the Hart Memorial Park turnout and conveyance The Kern Soccer Park 12-inch water would connect with the existing pipeline. County pipeline Yaw pipeline that provides raw water to the Kern County Soccer Park. The raw water would be used to irrigate the soccer park. References throughout this EIR to the Hart Park Memorial Park pipeline is to represent the turnout structures and pipelines for Hart Memorial Park and the Kern County Soccer Park. High Lift Pump Station A pump station to deliver the raw water from the pond to the proposed treatment plant will be constructed on the CALM site at the southwest end of the pond and adjacent to the future Morning Drive alignment. This station will consist of a series of able to deliver the raw water to pump pumps the proposed treatment plant at various flow rates and an elevation difference of approximately 350 feet. The discharge pipe will have a flow meter located just downstream of the pump station. A flow indicator and a totalizing (volume) recorder will be located at the pump station. The pump station would be constructed slightly below grade to partially screen views of the facilities and to minimize the length of pump casing. The height of the station will not exceed 12 feet above the existing pump grade. The area of land required for the high lift pump station and related facilities such as electrical power and switch gear housing is approximately 1,400 square feet. Water Treatment Plant The water treatment plant is proposed on approximately 40 acres southwest of Ant Hill, approximately 0.5 mile north of Paladino Drive. The water treatment plant is proposed to initially produce 10 million gallons per day (mgd) of drinking water. As growth continues in the northeast area, the treatment plant would be increased in size to a maximum of 60 mgd. The plant will include buildings that will house treatment processes, water treatment chemicals, laboratory facilities, pumping equipment, and .administrative functions. These buildings may extend up to 30 feet above the ground. The facility will also include open basins of water that will provide both storage and treatment functions. Partially buried water storage tanks will also be located on the site. The perimeter of the water treatment plant will be landscaped to enhance a natural appearance. Buildings and basins on the treatment site will be connected by a road network for access. The water treatment plant site will be accessed off of Paladmo Drive. The treatment plant will be connected to water pipelines that are proposed to be constructed under the access road and connected to the water pipelines proposed under the bike path alignment. ,02160007.EIR. doc III-4 Project Descript~'on Nor&east Bakersfield Bike Pa& and Water Facilities - Draft EIR Access Road An access road is proposed to provide vehicle access to the water treatment plant site. The new access road will extend from the existing paved portion of Paladino Drive (approximately 0.2 mile east.of the bike path alignment) to the bike path alignment. The access road will extend approximately 0.7 mile north of Paladino Drive along the bike path alignment then east 0.3 mile along the water pipelines to and from the water treatment plant. The access road will be 20 feet wide upon completion of construction. Water Pipelines A 54-inch raw water pipeline is proposed to extend from the high lift pump station to the proposed water treatment plant. The pipeline will be located along the proposed bike path for approximately 0.7 mile south of Alfred Harrell Highway and then extend to the southeast to the proposed water treatment plant site. From the water treatment plant, a 36-inch potable water pipeline is proposed to return to the bike path alignment with treated water. Other transmission lines will be constructed as required for future development. At the bike path, a 16-inch potable water pipeline is proposed to extend north along the bike path and a 36-inch potable water pipeline is proposed to extend south along the bike path. The 16-inch pipeline will extend on the west side of the proposed pond and existing County bike path. The 16-inch pipeline will connect to an existing potable water line that is located just north of the proposed Hart Memorial Park conveyance pipeline. This water pipeline will provide potable water to existing recreational uses as well as future development south of the Kern ~ver. The 36-inch pipeline is proposed to extend south of the water treatment plant along the proposed bike path to Paladino Drive. The pipeline will continue west adjacent to the bike path to Morning Drive and then 0.6 miles south to an existing 18-inch water pipeline at the Morning Drive/Panorama Drive intersection. The existing 18-inch water pipeline extends along Panorama Drive to the existing water tanks in the system. The connection between the proposed water treatment plant and the existing water tanks along Panorama Drive will allow direct use of existing water storage caPacity to serve the northeast residents. 111.3 PROJECT OBJECTIVES The City of Bakersfield is the lead agency for the project.

The 'vegetation in this area is primarily grassland. IV.2 RELATED PROJECTS Section 15310 of the CEQA Guidelines requires the consideration of cumulative impacts within an EIR. Cumulative impacts are defined as two or more individual effects which, when considered 02160007.EIR. doc IV-I General Description of Environmental Setting Northeast Bakersfteld Bike Path and Water Facilities - Draft EIR together, are considerable or which compound or increase other environmental effects. The individual effects may be changes resulting from a single project or a number of separate projects. The cumulative impact from several projects is the change in the environment which results from the cumulative impact of the project when added to other closely related future projects. In identifying projects which may contribute to cumulative impacts, the CEQA Guidelines allow the use of either a specific list of past, present and reasonably anticipated future projects, or a summary of projections contained in an adopted General Plan or related planning document which is designed to evaluate regionaI or areawide conditions. The cumulative analysis discussed in Section V is based upon reasonably anticipated future development in northeast Bakersfield. Table IV-I below provides a list of reasonably anticipated future projects within the northeast Bakersfield area. The location of these related projects are shown in Exhibit IV.2-1.

For each environmental topical area, a threshold of significance is provided for the reader to understand the basis upon which the level of impact was determined. Following is the organization of each environmental topical area within this section. · "Existing Conditions" describes the physical conditions which exist at this time and which may influence or affect the issue under investigation. · "Project Impacts" describes potential environmental changes to the existing physical conditions which may occur if the proposed project is implemented. · "Cumulative Impacts" describes potential environmental changes to the existing physical conditions which may occur with the proposed project together with all other reasonably foreseeable, planned, and approved future projects. · "Mitigation Measures" are those specific measures which may be required of the project in order to avoid an adverse impact; minimize an adverse impact; rectify an adverse impact by restoration; reduce eliminate adverse impact time by preservation and maintenance or over operations; or compensate for the impact by replacing or providing substitute resources or environment. The measures presented in this EIR are separated into those that would be implemented as part of project design and measures that would mitigate project impacts above and beyond any reduction in potential impacts accomplished by project design features. "Level of Significance After Mitigation" discusses whether the project and the project's contribution to cumulative impacts can be reduced to levels that are considered less than significant. V. 1 WATER RESOURCES I V.I.1 EXISTING CONDITIONS I Hvdroloknt/Drainaee The project area is located within the Kern River watershed. The Kern River originates in groups of I lakes Mount and has the North and South Forks which glacial near Whitney two principal tributaries, meet in Lake Isabella. Isabella Dam and Reservoir was completed by the U. S. Army Corps of I Engineers in 1954 and is a major flood protection facility along the Kern River. The 185-foot high, 1,695-foot long earthfill dam has a capacity to hold 568,000 acre-feet at the spillway and has peaked at over 630,.000 acre-feet during spillway operation. I 02160007.EIR. doc V. 1-1 Water Resources I Northeast BakersfieM Bike Path and Water Facilitt'es - Draft EIR The State of California Reclamation Board (Rec Board) has established a 100-year flood plain otherwise known as the designated floodway along the Kern River (see Exhibit V.I-1). The City of Bakersfield and the County of Kern currently regulate the secondary flood plain using a floodway that exceeds the Rec Board requirements. The designated floodway is based on a peak discharge of 15,000 cubic feet per second (cfs), which could be expected to occur about once in 100 years, on the average. The portion of the project site that is located north of Alfred Harrell Highway and within approximately 400 feet of the Kern River is within the County's regulated flood plain. There are several local drainages within the project area. Storm flows north of Alfred Harrell Highway are naturally conveyed to the Kern River by the existing gentle sloping terrain. South of Alfred Harrell Highway, a south to north natural drainage course extends along a canyon between Paladino Drive and Alfred Harrell Highway. This natural drainage turns west at approximately 2,000 feet north of Paladino Drive for approximately one mile. Approximately 2,000 feet south of Alfred Harrell Highway, a west to east tributary drainage course flows into the south-north natural drainage course. The west to east tributary drainage course extends for approximately one mile. Both the south to north and west to east drainage courses are designated by the U.S. Geologic Survey (USGS) as "intermittent blue stream." There is currently a drainage culvert'under Alfred Harrell Highway to allow storm flows to be conveyed from the south to the north side of the highway. Between Panorama Drive and Paladino Drive, the terrain gently slopes north and there is currently a natural drainage sump near the future Paladino Drive and Morning Drive intersection. Water Su[}olv The Metropolitan Bakersfield area currently has four sources of water: groundwater, Kern River, Central Valley Project (Friant-Kem), and the State Water Project. The City of Bakersfield is one of five water districts that has water rights on the Kern River. These water districts include: the North Kern Water Storage District, City of Bakersfield, Kern Delta Water District, Buena Vista Water Storage District, and Hacienda Water District (also representing Tulare Lake Basin Water Storage District). The City acquired water rights on the Kern River in 1976 averaging approximately 140,000 acre-feet per year (afy). The City also acquired storage rights in Isabella Reservoir in order to regulate peak summer snowmelt and provide winter storage carryover into future years. The City subcontracts to five irrigation districts for the use of a majority of the City's Kern River water rights. The remaining rights are used for miscellaneous water sales and groundwater banking in the City's 2800- acre recharge area located on the Kern River west of the City. During the 20-year period ending in 1997, the City was able to capture and bank for later use 442,585 acre-feet (af) in the 2800-acre facility. After subtracting uses (recovery, transfer, and losses), through the end of 1997, the City's water bank currently holds 193,194 af. Due to the wet winter and spring in 1998, the City anticipates 02160007.EIR.doc V. 1-2 14~ater Resources I i~!i lO0-Year Floodplain Southom Boundary PANO~MA DRIVE ~/~l~/jl~ ~ ~ Exhibit'~/r. 1-1 EIEII~EI o. 100-Year Floodplain Michael Brandman Associates 05220006 · 5/98 NORTHEAST BAKERSFIELD BIKE PATH AND WATER FACILITIES Nor&east Bakersfield Bike Pa& and Water Facilities - Draft EIR that by the end of 1998 an additional 60,000 afwould be recharged and added to their water stored in the water bank. The City's annual water recharge activity fluctuates based on amount of water available for recharge as well as amount of water pumped from the recharge area during "dry" conditions. The City has the capacity to pump approximately 40,000 afy from the recharge area to the City's existing water distribution and water exchange system. The City regulates the daily use of water in the Kern River and currently acts on behalf of the Kern River Water Master for the operations and record keeping requirements on the Kern River. The Water Master records flows at a location approximately two miles downstream of the project site to measure the amount of water that can be distributed to those who own Kern River water rights. This location is known as the First Point of measurement. Based on 45 years of flow records at First Point since the construction of Isabella Dam in 1954, there have been four years of critically "dry" conditions (1961, 1976, 1977 and 1990) and seven years of extremely "wet" conditions (1967, 1969, 1978, 1980, 1983, 1995, and now 1998). During critically "dry" conditions, districts who are deficient in Kern River water groundwater or purchase water from other sources. During "wet" conditions pump on the Kern River, water right holders store excess water in Isabella Reservoir and/or bank in the groundwater basin for later use during "dry" conditions. The Kern County Water Agency formed Improvement District No 4 (ID4) in 1971 which encompasses a large portion of the City. ID4 was formed to alleviate groundwater overdraft in Metropolitan Bakersfield and outlying areas by providing a supplemental surface supply. ID4 receives its water supply from the State Water Project and treats a portion of this water in a water treatment plant that is located at Golden State Highway and the Kern River. ID4 contracts for approximately 84,000 acre- feet per year. The ID4 project was designed to purify approximately 25,000 afy and wholesale the treated water to three water The remaining entitlement of about 59,000 afy is earmarked for purveyors. groundwater recharge operations in the ID4 district. The three water purveyors are California Water Service Company which contracted to receive 11,500 afy, North of the River Municipal Water District which contracted to receive 8,500 afy, and East Niles Community Services District which contracted to receive 5,000 afy. Each of these water purveyors is required to serve its ID4 water to areas that are located within ID4. The California Water Service Company (CWSC) service area encompasses an area that is east of Stine Road, north and south of the Kern River, south to approximately Tat~ Highway and east to the vicinity of the project area. Approximately 75 percent of the water used within this service area is from the groundwater. The remaining 25 of the water used is from the ID4 Based percent purchased project. on discussions with CWSC, existing water demand within CWSC's service area during the summer peak months could result in the use of approximately 115 mgd while demand during the winter months could be as low as approximately 28 mgd. Therefore, CWSC currently experiences a substantial change in water use within its service area from peak demand to Iow demand. During the low 02160007.EIR. doc V. 1-3 Water Resources Northeast BakersfieM Bike Path and Water Facilities - Draft E1R demand, CWSC reduces the use of groundwater wells. During peak months, CWSC reactivates groundwater wells to meet peak water demand. Water Quality Generally, the quality of the water in the Kern River is excellent for domestic water uses (after normal treatment) and meets Federal, State and local drinking water standards. Occasional high turbidity events are associated with storms in the Kern River basin. Storms occur primarily in the January through March period and the high turbidity can remain for as little as 1 day or as long as 5 days. The normal source of domestic water serving the northeast area, west of Morning Drive, is from ID4. Groundwater is used to supplement the ID4 supply from series of wells located 5 to 8 miles to the southwest, which is then pumped via a large transmission water main to the northeast. The native groundwater in the northeast area of the City is known to contain hydrogen sulfide, excessive levels of iron, and manganese, and generally does not meet primary public health standards for drinking water. The existing natural drainages south of Alfred Harrell Highway receive storm water from adjacent areas. The natural drainage course that is located approximately 2,000 feet north of Paladino Drive receives surface flows from an area that has a few active oil facilities (i.e. oil wells and tanks) as'well number of inactive oil wells. The quality of the surface water flows may be degraded due to a current and past oil activities. Furthermore, the area that is located south of Paladino Drive includes active and inactive oil facilities and surface flows within this area may also be degraded. V.1.2 PROJECT IMPACTS Thresholds of Significance A project is considered to have a significant impact if it would result in: · Uncontrolled runoffthat results in erosion and subsequent sedim6ntation of downstream water bodies; · Increases in runoffthat is in excess of downstream capacity; · Substantial increases in flooding in the project vicinity; · Reducing the water supply of downstream users; · Substantial degradation of the quality of surface water. 02160007.EIR. doc V. 1-4 Water Resources ! i N ortheast BakersfteM Bike Path and Water Facilities - Draft E1R Hydrology/Drainaee I Except through the ravine area and the portion of the bike path near Fail-fax Road, grading along the proposed bike path and pipeline is expected to nominally alter existing drainage patterns. The portion I of the bike Paladino Drive and the portion of the proposed water pipeline south of Paladino path along Drive and along Morning Drive are located on relatively flat terrain. The proposed bike path will I include asphalt concrete that will decrease the amount of pervious surfaces in this area and increase the amount of surface water runoff. However, this potential increase in runoff is expected to be nominal because the bike path would include approximately seven acres of impervious surfaces I extended 3.7 miles. over approximately I Within the ravine area, the bike path is proposed to traverse the existing natural drainage course in a few areas via a drainage culvert. Furthermore, the bike path would include additional drainage culverts to allow the natural surface runoff from the surrounding terrain to be conveyed to the natural Idrainage course. Historical flows into the existing natural drainage course are not expected to be substantially altered. I The portion of the bike path near Fairfax Road will increase runoff toward Fairfax Road due to the placement of asphalt concrete on relatively steep terrain; however, due to the relatively nominal Iamount impervious surfaces created by the placement of asphalt concrete, no substantial increases in storm water flows are expected. I The grading for the proposed water treatment plant will alter the drainage patterns of the water treatment plant site. It is anticipated that the placement of impervious surfaces on the water treatment I plant site will increase flows into the natural south to north channel. This increase in surface drainage water flows could result in significant long-term erosion and sedimentation into the natural drainage I channel. Grading activities associated with the pipeline facility south of Paladino Drive and along Morning I Drive will be lOcated relatively flat terrain.

Surface water south of the proposed pond is expected to flow to the northeast toward the Kern River. No significant I 02160007.EIR. doc V. 1-5 Water Resources I Northeast BakersfteM Bike Path and Water Facilities - Draft EIR 'alteration of surface drainage patterns are expected to occur with the implementation of the proposed water facilities north of Alfred Harrell Highway. Water Supply Implementation of the proposed project includes water facilities that are designed to initially convey 10 million gallons per day (mgd) (15.5 cubic feet per second [cfs]) of water to the proposed water treatment plant. The start-up design of the water treatment plant will be to treat 10 mgd (15.5 cfs) by 2002 and distribute the potable water primarily to new and existing customers in the vicinity of the project area. Additionally, the plant will, at times, supplement and replace water to existing customers to the west that' are using groundwater or ID4 water. As increased water demand occurs, the project envisions a step-up to 20 mgd (3l cfs) by 2007 and 40 mgd (62 cfs) by 2012. At the time of full buildout of the proposed water treatment plant, the high lift station will pump a maximum of 60 mgd (93 els) of water to the proposed water treatment plant, and the turnout structure at the pond will divert 11 mgd (17 cfs) to recreational uses north of Alfred Harrell Highway for Hart Memorial Park, Kern County Soccer Park, and CALM. The 17 cfs to the recreational facilities are not additional flows from the Kern River, but a rediversion from existing take out structures. Removal of these existing structures will follow the implementation of the project. The provision of one intake structure along the Kern River that would allow the existing diversion structures along the Kern River (i.e., diversion for Hart Memorial Park, Kern County Soccer, Park, and CALM) to be removed and provide more reliable water supply for existing recreational uses. The City of Bakersfield will operate the facilities that withdraw the water from the Kern River, store the raw water in ponds and convey raw water to the recreational facilities. No effect on existing water entitlements or downstream users would occur with the withdrawal of water from the Kern River because the City would only be using its own water entitlements and water that it has previously stored and banked within the 2,800-Acre Groundwater Recharge area. The City would use its own water rights through the use of exchanges and direct use of miscellaneous entitlements. CWSC will be responsible to pump the raw water from the high lift station and convey the raw water to the water treatment plant within a 54" diameter raw water pipeline. The proposed water treatment plant will allow CWSC to serve new lands proposed for development in the immediate area of the plant. CWSC will also be able to augment its current water sources (groundwater and existing ID4 water treatment plant) to existing City customers with high quality Kern River water. During the non- summer months, the average water use is expected to be approximately 50 percent of peak use. This reduction in water use will ultimately allow CWSC to continue treating 60 mgd during non-summer months, thereby reducing groundwater pumping in existing downtown and south-central areas of the City. This curtailment of groundwater pumping will have the effect of preserving the groundwater in place for use during critically dry or emergency periods. 02160007.EIR.doc V. 1-6 Water Resources Nor&east BakersfteM Bike Pa& and Water Facilities - Draft EIR The historic average daily flow of the Kern River at First Point, since the completion of Isabella Dam, is 642 mgd (993 cfs). During critically "dry" conditions, the City may, for short periods of time be limited in the ability to withdraw the maximum design flow of 71 mgd (110 efs) from the Kem River. Based on a review of the flow records of the Kern River at First Point since 1954, the minimum average daily flow exceeded 71 mgd (110 cfs) 99.8 percent of the time and exceeded 56 mgd (87 cfs) 100 percent of the time. The future water demand needed to serve new developments under this project is projected to be approximately 20 mgd (31 cfs). An additional 11 mgd (17 cfs) of raw water will be diverted to the Hart Memorial Park conveyance pipeline for continued use by the County recreational facilities. Under full build-out of the project, future~'water demand for summer months is projected to be 71 mgd (110 cfs) which represent 60 mgd (93 cfs) for conveyance to the water treatment plant and 11 mgd (17 cfs) for the existing County recreational facilities. Operational criteria for CWSC would dictate that during those periods of critically dry or low flows on the Kern River, the treatment plant would scale down its requirements to serve only those new customers in the immediate vicinity of the plant. The customers in the existing system would revert to groundwater supplies built up by the supplementary water program by reactivating the groundwater wells to supplement the water received by the City. If a contamination spill (i.e., chemicals or oil) occurred along the Kern River upstream of the proposed intake structure, the City could stop withdrawing water from the Kern River and provide the water stored in the raw water pond to CWSC. The pond will have an operational capacity of approximately 120 af which is equivalent to 20 mgd (31 cfs), or two days storage to the plant. In addition to the stored pond water, CWSC would utilize existing above ground storage capacity in their distribution system and reactivate groundwater wells to provide a back-up supply of water to the northeast area. Water Quality Development of the proposed project will result in short-term and long-term surface water quality impacts. Short-term impacts will occur during construction activities. These activities may increase the amount of erosion which could increase sedimentation in surface water exiting the project area. Construction equipment may also increase the chance of toxins, such as oil, gas, and solvents, within the surface water exiting the project area and eventually into the Kern River or the natural drainage channels. This potential increase in sediment and toxins is considered a significant short-term impact on surface water quality. Long-term operational activities for the majority of the proposed facilities would result in nominal impacts on surface water quality. The proposed water treatment plant will result in employee traffic and deliveries entering and exiting the water treatment plant site. This traffic could increase the potential for storm water runoff transporting surface water constituents form roadway surfaces. 02160007.EIR. doc V. 1-7 Water Resources ! Northeast BakersfteM Bike Path and Water Facilities - Draft EIR ! Typical urban runoff pollutants (i.e., oil and grease, heavy metals, solvents) can be expected within runoff exiting the water treatment plant site. Since the 60 mgd proposed water treatment plant is · expected to employ a maximum of 20 to 30 people, daily trips associated with employees and as well as deliveries to the plant are not expected to result in a significant increase in urban runoff pollutants. No significant long-term surface water impacts would occur with project implementation. V. 1.3 CUMULATIVE IMPACTS 1 Implementation of the proposed project and the related projects will increase impervious surfaces (which will increase runoff) and add incrementally to the amount of pollutants discharged into the 1 project vicinity's drainage system. The implementation of both the project and the related projects is not expected to result in a significant cumulative impact on drainage systems because the related · projects do not drain into the same drainage systems as the proposed project. Furthermore, the related projects will increase the long-term demand for water in the northeast Bakersfield area. The proposed project would not contribute to an increased long-term demand; however, the project would provide a ! beneficial impact on water supply in the northeast Bakersfield area. The proposed project would not contribute to significant cumulative impacts on water resources. V. 1.4 MITIGATION MEASURES Hydrology/Drainage WR-1. Prior to the issuance of a 'conditional use permit, the project applicant for the water treatment plant will be required to demonstrate that storm water flows conveyed offsite shall not exceed the historical flows offsite. To demonstrate this, the project site may need · to be designed so that storm water can be retained onsite and release at historical flows. 1 Water SuDnlv I No measures are required. 1 Water Quality · I WR-2. Prior to the issuance of a grading permit, an erosion control plan for construction activities that describes the siting and maintenance of temporary sediment collection basins shall be prepared. Similarly, the use of filter fences, filter dikes, and other construction site best · management practices (BMPs) near storm water system outlets shall be described. · WR-3. The applicant shall be responsible for filing a Notice of Intent (NOI) to be covered by the · General Construction Permit for new development under the National Pollution Discharge 1 Elimination System (NPDES) Storm water Discharge Program.

Prior to the approval of a landscape plan for the proposed water treatment plant site, all proposed cut-and-fill slopes shall be designated with landscaping to reduce potential erosion and increased runoff. V. 1.5 LEVEL OF SIGNIFICANCE AFTER MITIGATION With the implementation of the above measures, no significant impacts to water resources would occur. 02160007.EIR. doc V. 1-9 Water Resources I Northeast Bakersfield Bike Path and Water Facilities - Draft EIR V.2 BIOLOGICAL RESOURCES The following incorporates information contained in a biological resource assessment prepared for the proposed project by Bio Resources Consulting (BRC) in July 1998. The complete report is located in Appendix B. I V.2.1 EXISTING CONDITIONS 1 Regulatory Framework Activities associated with construction, operation, and maintenance of the proposed project have the 1 potential to impact federal and/or state-listed species. Therefore, the project is subject to the Federal · Endangered Species Act (FESA) and California Endangered Species Act (CESA). The following 1 provides a brief summary of the regulatory framework provided by FESA and CESA. Federal and State Endangered Species Acts I FESA protects federally-listed threatened and endangered species. Section 10 of FESA prohibits acts which result in "take" of threatened or endangered species. "Take" is defined as killing, harming, or harrassment of listed species. "Harm" has been further defined to include killing or injuring due to · significant obstruction of essential behavior patterns (i.e. breeding, feeding, or sheltering) through significant habitat modification or degradation. I Two sections of FESA contain provisions for allowing "take" which is incidental to otherwise lawful activities. Under Section 7, a federal agency which proposes to conduct, fund, or approve an action · which may result in "take" of listed species is required to conSult with the U.S. Fish and Wildlife 1 Service (USFWS). The result of this formal consultation is a Biological Opinion, which includes either Ill Or nonjeopardy decision issued by USFWS to the consulting federal agency. Included in the a jeopardy Biological Opinion is the possible issuance of authorization for "incidental take". Section 10(a) of FESA provides a method for permitting a state or private action which may result in "incidental take". 1 Under Section 10(a), the project proponent must provide the USFWS with a Habitat Conservation Plan for the affected species, and publish notification of the application for a permit in the Federal Register. I CESA provisions to permit impacts to California-listed rare, threatened, or endangered species are similar in that there is a permit process. The applicant must enter into a management agreement with the California Department of Fish and Game (CDFG). This management agreement specifically defines the permitted activities and how the applicant must act to protect affected species. I 02160007.EIR. doc V. 2-1 Biological Resources I Northeast Bakersfield Bike Path and Water Facilit~'es - Draft EIR The majority of the project site lies within the geographic area covered by an existing HCP, the Metropolitan Bakersfield Habitat Conservation Plan (MBHCP). The MBHCP was implemented in August 1994 by the City of Bakersfield and the County of Kern to allow development and similar activities to occur in exchange for habitat conservation for the affected species. Section 404 of the Clean Water Act (CWA) The U.S. Army Corps of Engineers (ACOE), under Section 404 of the Clean Water Act, regulates discharges of dredged or fill material in "waters of the United States." The term "waters" includes wetlands and non-wetland bodies of water that meet specific criteria as defined in the Code of Federal Regulations (CFR). The definition of "waters of the United States" includes "...intrastate lakes, rivers, streams (including intermittent streams)...the use, degradation or destruction of which could affect interstate or foreign commerce..." and tributaries of water defined as waters of the United States. Some intermittent washes may also qualify as waters of the United States. Areas which meet the definition of waters of the United States,. or the definition of wetlands, could be under ACOE jurisdiction. At the discretion of the ACOE, impacts to these areas could require a permit, depending on the type and size of the activity within ACOE jurisdiction. California Fish and Game Code: Sections 1600 - 1603 Any activity that will divert or obstruct the natural flow or change the bed, bank, or channel of any river, stream, or lake must provide a Streambed Alteration Notification to CDFG. Additionally, Streambed Alteration Notification is required if streambed material is proposed for removal. Providing Streambed Alteration Notification to CDFG may result in a Streambed Alteration Agreement between the project applicant and CDFG. Construction activities in intermittent streams may also require a Streambed Alteration Agreement. Methods A list of special status species which could potentially occur in the vicinity of the project site was compiled by consulting pertinent literature, accessing the CDFG Natural Diversity Data Base, and contacting certain persons familiar with local and regional biological resources. I Biological field surveys were conducted between April and June, 1998. The proposed bike path and water pipeline routes were walked using belt transects. The centerline plus a 150 buffer on either side of the centerline was surveyed for special status plant and wildlife species. Although surveys were not I conducted at an appropriate time for observation of some special status annual plants, habitat suitability for these species was evaluated during the surveys. If observed, important habitat elements I 02160007.EIR. doc V.2-2 Biological Resources I ! Northeast BakersfieM Bike Path and Water Facilities - Draft EIR for special status species were noted and mapped (i.e. elderberry shrubs for Valley elderberry longhorn beetle). In addition, plant communities were mapped. Direct observations of special status species and their "sign" (scat, tracks, tail drags, etc.) were noted if encountered during the surveys. One person-day was spent on the riparian area adjacent to the Kern 1 1 River to document bird species using this area. San Joaquin kit fox were assumed to be present in the project vicinity based on past direct observation of kit fox and presence of known kit fox dens near the project site. Therefore, scent station surveys and spotlighting were not conducted for this species. 1 Only known San Joaquin kit fox dens were mapped, including suspected pupping dens. Known dens 1 1 are those burrows or artificial structures which measure between approximately 4 and 12 inches in height, which exhibit sign (scat, tracks, claw marks, prey remains) indicating past or present kit fox use, or other characteristics which, in the judgement of the biologist, are characteristic of dens which 1 have been used by kit fox. Potential San Joaquin kit fox dens are burrows or artificial structures which meet the same size criteria as known dens, but exhibit no sign of kit fox use. Due to the large number of squirrel colonies within the survey that contain burrows meeting the criteria for potential dens, and the length of time before 1 project construction is likely to commence, potential kit fox dens were not mapped. Vegetation Communities For purposes of this biological resource assessment, the vegetation of the project area may be adequately described utilizing the descriptions defined in Holland (1986). Where an equivalent series has been identified by Sawyer and Keeler-Wolf (1995), it is shown in parentheses. Exhibits V.2o 1 and V.2-2 illustrate the vegetation communities within the project study area. I Non-native grassland (California annual grassland series) This community is the primary vegetation of the survey area, and is distributed throughout the project area, both as a community and as an understory component to valley saltbush scrub. It is likely that frequent fires maintain this community in the vicinity of the project site. Non-native grasses dominate (bromes, foxtail, fescues, and oats), with showy annual forbs present to a varying degree depending on rainfall. Forbs which are typically present include red-stemmed filaree (Erodium cicutarium), owl's clover (Castilleja exserta and C. attenuata), lupines (Lupinus spp.), goldfields (Lasthenia californica), fiddleneck, gilia, and several mustards.

Northeast BakersfieM Bike Path and Water Facilities - Draft EIR germinating in late fall and most species flowering in early to late spring. This community is widely distributed through California, generally below 3,000 feet in elevation. Valley Saltbush Scrub (aliscale series) In the project area, shrub cover in this vegetation community is typically dominated by common saltbush (Atriplex polycarpa). Other shrub species which may be present include spiny saltbush (A. spmifera), cheesebush (Hymenoclea salsola), and pale-leaf goldenbush (Isocoma acradenia var. bracteata). The understory typically consists of winter-germinating annuals dominated by non-native such as bromes (Bromus spp.), wild oats (Avena barbata and A. fatua), foxtail (Hordeum spp.), grasses and fescues (Vulpia spp.). Native spring-flowering annuals may include bird's eye gilia (Gilia tricolor), fiddleneck (Arnsinclaa menz~esii var. mtermedia), white layia (Layia glandulosa), and several species of phacelia (Phacelia spp.). On the project site, this community also contains shrubs which are more typically elements of Interior Coast Range saltbush scrub, such as matchweed (Gutierrezia californica) and bladderpod (Isomeris arborea). Riparian Riparian vegetation found along the Kern River within the project area is not easily described using either the Holland (1986) or the Sawyer and Keeler-Wolfe (1995) classification systems. This is primarily due to the regulation of flows and lack of overbank flooding which was likely historically frequent. Under the Holland system, riparian areas most closely resemble an intergrading of Great Valley Cottonwood Riparian Forest and Great Valley Mixed Riparian Forest. The overstory of the dyer bank is dominated by primarily Fremont cottonwood (Populus fremontiO farther from the river edge and Goodding's black willow (Salix gooddingii), mulefat (Baccharis salicifolia), and quail bush (Atriplex lenttforrms) closer to the river's edge. The upper bank also contains small areas of Arrowweed Scrub dominated by arrowweed (Pluchea sericea). Other prominent trees and shrubs in the riparian areas include California sycamore (Platanus racemosa) and elderberry (Sambucus mexicana). The Sawyer and Keeler-Wolfe classifications do not include several potential series corresponding to the tree dominated communities. The arrowweed dominated areas would also be classified as Arrow weed series under this system. The riparian habitat adjacent to the Kern River in the project area was identified as having low habitat sensitivity by Dames and Moore (1990), based on lack of well-developed understory vegetation. I 02160007.EIR.doc V.2-4 Biological Resources I Northeast BakersfieM Bike Path and Water Facilit~'es - Draft EIR Sensitive Biological Resources Sensitive habitats are vegetation communities that support concentrations of sensitive plant or wildlife species, are of relatively limited distribution, or are of particular high value to wildlife. Sensitive habitats are not afforded legal protection unless they support protected species. A ~ederally endangered species is one facing extinction throughout all or a significant portion of its geographic range. A federally threatened species is one likely to become endangered xvithin the foreseeable future throughout all or a significant portion of its range. The presence of any federally endangered or threatened species in the project area generally imposes severe constraints on development, particularly if development would result in a "take" of the species or its habitat. The term take means to harass, harm, pursue, hunt, shot, wound, kill, trap, capture, or collect, or to attempt to engage in such conduct. Harm in this sense can include any disturbance to habitats used by the species during any portion of its life history. The state of California considers an endangered species one whose prospects of survival and reproduction are in immediate jeopardy. A threatened species is one present in such small numbers throughout its range that it is likely to become an endagered species in the near future in the absence of special protection or management, and a rare species is one present in such small numbers throughout its range that it may become endagered if its present environment worsens. Rare species only applies to California native plants. State threatened and endagered species include both plant and wildlife species and are fully protected against take, as defined above. Species of Special Concern is an informal designation used by the CDFG for some declining wildlife species that are not state candidates. This designation does not provide legal protection, but signifies that these species are recognized as sensitive by CDFG. The Califomia Native Plant Society (CNPS) is a local resource conservation organization that has developed an inventory of California's sensitive plant species. This inventory is the summary of information on the distribution, rarity, and endangerment of California's vascular plants. This rare plant inventory, is comprised of four lists. CNPS presumes that List lA plant species are extinct in California because they have not been seen in the wild for many years. CNPS considers List ~ B plants as rare, threatened, or endangered throughout their range. List 2 plant species are considered rare, threatened, or endangered in California, but more common in other states. Plant species on lists lA, lB, and 2 meet CDFG criteria for endangered, threatened, or rare listing. Plant species for which CNPS needs additional information are included on List 3. List 4 plant species are those of limited distribution in california whose susceptibility to threat appears low at this time. I 02160007.EIR. doc V.2-5 Biological Respurces , !

Suitable habitat for this species is non-alkaline to slightly alkaline sandy loam soils of relatively undisturbed grassland communities below an elevation of 3,000 feet. 02160007.EIR. doc V.2-6 Biological Resources Nor&east BakersfieM Bike Pa& and Water Facilia'es - Draft EIR Historically, the range of the species included the upper San Joaquin and adjacent valleys from Coalinga in the northwest to the Cuyama Valley in the southwest. Of 55 historical locations, approximately twenty extant populations remain (Skinner and Pavlik 1994). Recently, extant populations have been found on the Camzo Plain in San Luis Obispo County, and in the Kreyenhagen Hills of Fresno County. An attempt has been made to establish an artificial population at the Paine Wildflower Preserve, Kern County. California jewelflower was not observed during the surveys; however, surveys were completed too late in the season to identify this annual. The nearest presumed extant location for California jewelflower is several miles to northeast, off of Rancheria Road in the low Greenhorn Range foothills. Although some marginally suitable habitat was present, frequent grass fires, offroad vehicle use, oil development, and other disturbances make it unlikely that this species occurs in the project area. Hoover's wooly star (Eriastrum hooveri), a CNPS List 4 species and a previously federally-listed endangered species, is a small annual species that reaches a height to 6 inches. Flowers usually appear in mid-to late spring (April to May). The habitat for Hoover's wooly star is valley grassland with scattered saltbush (Atriplex polycarpa or A. spinifera). The plants are often found in openings in Atriplex Scrub where cryptogamic crusts have developed on the soil surface. Associated species include red brome, annual fescue, and goldfields (Lasthenia californica). This small, ephemeral, annual species was once fairly widespread on the crusty alkaline soils of the San Joaquin Valley. Hoover's wooly stax is known to occur from Fresno County and Kern County (Bakersfield area and ,ill west and northwest of Bakersfield). It is known from the Carrizo Plain (San Luis Obispo County) and the Cuyama Valley (Santa Barbara County). The species has subsequently been found at many sites the Elk Hills in Kern County and is in the process of being downlisted. bordering The survey was conducted at an appropriate time for observation of Hoover's wooly star. However, 1 this species was not observed during the surveys. San Joaquin wooly threads (Lembertia congdonii), a federally endangered and CNPS List 4 species, is a small, inconspicuous annual which may be 1 to 10 inches in height at maturity. Tiny yellow ray and disk flowers appear in late February or March. San Joaquin wooly-threads are found in valley grassland habitat types with silty sand or sandy loam soils at elevations ranging from 400 feet to 1,200 feet. Valley saltbush is often the dominant shrub in these habitat types. The preferred microhabitat for this species consists of areas with reduced annual grass competition. It is generally not found where annual grasses are extremely dense and tall (Taylor 1987). Known extant populations in Kem County occur along the Kern River near 1-5, near Lost Hills, and on the Belridge Plain. 02160007.EIR. doc V. 2 -7 Biological Resources ~. t, Nor&east Bakersfield Bike Pa& and Water Facdit~es - Draft EIR This species was once fairly common in the San Joaquin Valley. Various land conversion activities have eliminated most of its habitat, which is why it was listed by the USFWS as an endangered species. An occurrence for San Joaquin wooly threads is recorded by the CNDDB approximately two miles west of the Fairfax Drive terminus of the bike path. However, this population was last seen in 1905 and is very likely extirpated. No suitable habitat was observed during the surveys for the project. Although the survey was conducted too late in the year to identify this species, it is unlikely that it occurs within the project area. In addition, other surveys conducted during the appropriate period in the vicinity have not resulted in observation of this species. Bakersfield Cactus (Opuntia basilaris var. treleaseO, a state and federally-endangered species and a CNPS List lB species, is a beavertail-type cactus with bright, magenta-pink flowers appearing between April and May. Bakersfield cactus occurs primarily on sandy soils of alluvial plains, washes, and ridges, in grassland and saltbush scrub vegetation. Although it was once common from just north of Bakersfield south along the western flank of the foothills to the vicinity of Wheeler Ridge, much of the cactus has been eliminated through urbanization and disking of grazing lands. Remaining populations are fragmented, occumng in pockets which have been less disturbed. Five areas containing Bakersfield cactus were observed during the surveys. Three of these populations were within the potential construction corridor and two were observed within the buffer area. These populations represent remnant populations of this cactus, which once formed "dense almost impenetrable colonies" throughout the area. Approximately 20 cactus clumps were observed in the five areas. Other Sensitive Plant Species Slough thistle (Cirsium crassicaule), a CNPS List lB species, is a biennial species, which to appears grow as an annual. This species is distinguished from the weedy Cirsium species by the presence of pinnate spines on the phyllaries. The slough thistle is a tall robust annual that ranges from 3 to 6 feet in height. The lower stem is typically unbranched while the upper portion is commonly much branched, supporting several paniculately disposed heads. Herbage is prominently hoary-tomentose to sometimes glabrescent on the surfaces. Individual leaves are lanceolate in overall shape with upper sinuate-pinnatifid margins. Individual lobes are often spine-tipped. Flowers are whitish to pinkish. Slough thistle is found in low-lying, seasonally to permanently wet habitats on the valley floor. The population locations in Kern and Kings counties indicate that this plant can tolerate disturbed habitats. 02160007.EIR. doc V.2,-8 Biological Resources Northeast BakersfieM Bike Path and Water Facilities - Draft EIR The northern populations of this species (in San Joaquin County) tend to be disjunct, which suggests possible dissemination by water or equipment. This species was not observed during the field survey. Gypsum-loving larkspur (Delphinium gypsophilum ssp. Gypsophilum), a CNPS List 4 species, is a perennial in the buttercup family which reaches a height of up to 4.5 feet. It has a white, inconspicuous flower within generally white sepals along the flowering raceme. As its name implies, gypsum-loving larkspur frequently occurs on gypsum-rich soils in chenopod scrub and grassland habitats. In favorable years, it occurs on north-facing slopes with other soil types as well. This species was not observed during the field survey. One population of cottony buckwheat (Eriogonum gossypinum), a CNPS List 4 species, was observed on the fi~ture Paladino Drive portion of the bike path route in the buffer area, near Fairfax Drive. No other plant species of concern were observed during the surveys. The species grows on exposed clay hills, typically south-facing. Its distribution includes the southwestern San Joaquin Valley and low foothills of the Greenhorn Range. Sensitive Wildlife Species Sensitive wildlife species that were observed or potentially occur within the project study area are listed in Table V.2-2. The list of special status species that could potentially occur in the project survey area was compiled by consulting pertinent literature, accessing the CNDDB, and contacting cetain persons familiar with local and regional biological resources. Following is a discussion of endangered and threatened wildlife species, and other wildlife species of concern. No endangered or threatened wildlife species were observed during the surveys. However, signs of site utilization by endangered and threatened species were observed. Endangered and Threatened Wildlife Species Valley Elderberry Longhorn Beetle (Desmocerus californicus dimorphus) has a historic range that includes the entire Great Central Valley from Redding south to Bakersfield. Formerly extensive riparian forests along major drainages are thought to have supported this species on elderberry shrubs. The species depends on elderberry for all phases of its life cycle, larvae, pupae, and adult. No species specific surveys were conducted for valley elderberry longhorn beetle. The Kern River watershed is on the edge of this species' range; however, it is not known to currently occur in the vicinity of the project site. Several elderberry (Sambucus mexicanus), the genus exclusively used by this species, were observed in the riparian habitat adjacent to the Kern River. Therefore, this species may be present in the project area. 02160007.EIR. doc V. 2;9 Biological Resources Northeast Bakersfield Bike Path and Water Facilities - Draft EIR TABLE V.2-2 SPECIAL STATUS WILDLIFE SPECIES WITH POTENTIAL TO OCCUR Invertebrates Desmocerus californicus dimorphus T / - Riparian habitat, occurs on host plant, Valley elderberry longhorn beetle elderberry (Sambucus spp.) Helminthoglypta callistoderma SC / - Margin of the Kern River, along lower Kern Kern shoulderband River canyon Reptiles and Amphibians Clemmys marmorata pallida C / CSC Freshwater marsh, ponds, and other slow- southwestern pond turtle moving and still waters Gambelia sila E/E Open saltbush scrub and grassland habitats, blunt-nosed leopard lizard roads and open washes Phrynosoma coronatum SC / CSC Open shmblands and grasslands with sandy California homed lizard soils Birds Accipiter cooperi - / CSC Regular migrant and winter visitor in open Cooper's hawk woodlands, riparian areas Accipiter striatus - / CSC Frequently seen during winter in riparian sharp-shinned hawk areas Aquila chrysaetos BEPA / CSC Resident of open grasslands and low golden eagle foothills Athene cunicularia - / CSC Valley grasslands and open saltbush scrub Burrowing owl Buteo swainsoni - / T Migrant through the valley and infrequent Swainson's hawk nester along Kem River and other woodlands of Kern County Circus cyaneus - / CSC Common resident of marshlands and Northern harrier grasslands Empidonax traillii E / E Prefer willow thickets in good quality Willow flycatcher riparian habitat for nesting Falco mexicanus - / CSC Resident which forages in open grassland prairie falcon areas, nests in cliff faces or on ledges Haliaeetus leucocephalus T~ / E Rare winter visitor along Kern River; bald eagle unlikely to roost Lanius ludovicianus SC / CSC Resident which forages in scrub and Loggerhead shrike adjacent grassland habitats, may nest in riparian woodland 02160007.EIR. doc V.2-10 Biological Resources 1 Northeast Bakers, fieM Bike Path and Water Facilities - Draft EIR Pandion haliaetus - / CSC Rare winter visitor, foraging in riparian and Osprey open water habitats Toxostoma lecontei - / CSC Prefers mature saltbush scrub for nesting LeConte's thrasher Vireo bellii pusillus E / E Dense willow thickets for nesting Least Bell's vireo Mammals Ammospermophilus nelsoni - / T Shrublands, especially along washes San Joaquin antelope squirrel Dipodomys nitratoides brevinasus SC/CSC Western and southern side of the San short-nosed kangaroo rat Joaquin Valley, saltbush scrub and other alluvial plain and low foothill habitats Taxidea taxus - / CSC Grasslands and shrublands of the San American badger loaquin Valley and surrounding low foothills Vulpes macrot~'s mutica E / T Grassland and scrub habitats of the San San Joaquin kit fox Joaquin Valley and surrounding foothills Status Abbreviations: Federal E - federally listed as endangered T - federally listed as threatened (~ - Bald eagle and golden eagle are also protected by the Bald Eagle Protection Act) C - federal candidate category l for listing as threatened or endangered; sufficient information is available to publish a proposed rule regarding listing SC - former Category 2 Candidates for listing; this category was eliminated in 1996 (CFR ...), however, species were retained as "federal species of concern" State E - state-listed as endangered T - state-listed as threatened CSC - CDFG species of special concern 1.

Sources: CDFG (1998), CDFG (1992), Jones and Stokes (1988), MBHCP Steering Committee (1994), and Zeiner (1988) · Blunt-nosed leopard lizard (Gambelia sila) is a relatively robust lizard with a large head and blunt snout. It was historically distributed over the San Joaquin Valley adjacent lower foothills, plains, and valleys. Blunt-nosed leopard lizards are active during the day, primarily between the months of April and October. Leopard lizards occur on sparsely vegetated plains, lower canyon slopes, on valley floors, and in washes. Associated vegetation may include a variety of grasses, saltbush, golden bush, iodine bush, and seepweed. Species specific surveys for blunt-nosed leopard lizard were not conducted. Although suitable habitat for this species was observed along the route, much of it was highly impacted by off-road vehicles. Most of the route consisted of very dense annual grasses such as foxtail (Hordeum leporinum), bromes (Brornus spp.), and wild oats (Avena barbata), which are generally poor habitat for this species. o2troooT.Em, aoc V.2-11 Biological Resources Northeast Bakersfield Bike Path and Water Facilities - Draft EIR Direct observations by BRC and discussions with other biologists familiar with the area resulted in several known locations for this species which did not appear in the CNDDB, primarily in the vicinity of the southern half of the project site. The nearest locations include observations about 1 mile west of the proposed water treatment facility, about 1.5 miles south of Paladino Drive and 0.5 miles east of Morning Drive, and near the base of Ant Hill (about 0.5 miles east of the proposed water treatment plant site). Therefore, blunt-nosed leopard lizards may occur on the project site. Swainson's Hawk (Buteo swainsonil) is a medium-sized, dark breasted hawk of grasslands and open woodlands in Califomia, preferring riparian trees for nesting. Certain types of agricultural fields adjacent to riparian areas also provide foraging habitat for nesting pairs. Diet includes rabbits, lizards, snakes, frogs, and occasionally insects. Reduction of riparian habitat in California has reduced the nesting range of this species to primarily the Sacramento Valley, with occasional nesting to the south through Kem County. Fairly large numbers of these hawks migrate through the Central and San Joaquin valleys to their wintering grounds in South America. The southern San Joaquin Valley is frequented by migrating Swainson's hawks and, infrequently, nesting pairs are observed. A nest site was used by a pair of Swainson's hawks along the Kern River west of Bakersfield in 1998. Although suitable nesting sites are available along the Kern River portion of the project, no Swainson's hawks or their nests were observed during the surveys. This species has not been historically reported to nest along the portion of the Kern River adjacent to the project area. Willow Flycatcher (Empidonax trailii) nests in shrubby habitat, frequently willows, near streams, ponds, and wet meadows. In 1986, it was estimated that there were as few as 150 nesting pairs in California. Reduction of riparian habitat through clearing and channelization of streams and rivers and nest parasitism are the major threats to this species. Although riparian vegetation, including some riparian scrub areas were observed along the Kern River, the structure and extent of this habitat is unlikely to be sufficient at this time to support nesting for this species. It was not observed during project surveys nor have they been known to nest along this portion of the Kern River for several decades. Bald Eagle (Haliaeetus leucocephalus) is a very large, easily recognizable raptor (adults) and breeds in northern California, from near Lake Tahoe north through the Cascade Range and west to the Coast Range. Bald eagles winter through much of the state, the exception being the Mojave Desert and high areas of the Sierra Nevada. With a diet of primarily fish, bald eagles need reservoirs, lakes, and rivers 02160007·EIR.doc V. 2-1 2 Biological Resources Northeast BakersfieM Bike Path and Water Facilities - Draft EIR for foraging. The species is infrequently sighted during winter along the Kern River, and is unlikely to roost here. No bald eagles were observed. Least Bell's Vireo (Vireo bellii pusillus) is a small, gray and white songbird, once bred through much of California, using willow, wild rose, and other thickets along riparian areas for nesting. It has not been recorded nesting along the lower Kern River in several decades. San Joaquin Antelope Squirrel (Ammospermophilus nelsoni) is a small, yellow-brown squirrel with two distinguishing white stripes along dorsal side of the body. In contrast to other listed mammals in their range, these squirrels are diurnal and are active year-round. San Joaquin antelope squirrels are most often found in grasslands or open shrublands. Associated shrubs include saltbush, ephedra, bladder pod (Isomeris arborea), goldenbush (Isocoma acradenius= Haplopappus a.), snakeweed (Gutierrezia bracteata), and others. San Joaquin antelope squirrels are omnivorous, with a diet consisting primarily of grass and herb seeds and insects (CDFG 1989). Surveys were conducted under appropriate conditions to observe this species. However, San Joaquin antelope squirrels were not observed during site surveys. Although suitable habitat is present, it is unlikely that this species occurs on the project site. Despite extensive surveys in the vicinity of this particUlar project site, no San Joaquin antelope squirrels have been observed. It is thought that they may be extirpated from this area based on the fact that no antelope squirrels have been observed north or east of Bakersfield since the 1970's. San Joaquin Kit Fox (Vulpes macrotis mutica) is one of the eight recognized subspecies kit fox. San Joaquin kit foxes are generally nocturnal and are opportunistic carnivores. They feed on rodents, lagomorphs, birds, reptiles and insects, as well as on carrion such as road kills. Studies indicate that the primary food items may vary geographically and seasonally. San Joaquin kit foxes occur in Valley Saltbush Scrub, Valley Sink Scrub, Interior Coast Range Saltbush Scrub, Upper Sonoran Sub-shrub Scrub, Non-native Grassland, and Valley Sacaton Grassland. Three known San loaquin kit fox dens were observed along the bike path route on the future "~ladino Drive alignment. One of these dens was a suspected puppy den. Two known San Joaquin kit fox dens were also observed on the proposed water treatment plant site. Potential dens were common, primarily within the widespread ground squirrel colonies in the survey area. It is likely that San Joaquin kit fox forage over the entire site. 02160007.EIR. ao¢ V.2-13 Biological Resources Nor&east Bakersfield Bike Pa& and Water Facilities - Draft E1R Other Wildlife Species of Concern Kern shoulderband (Helminthoglypta callistoderma) is a federal species of concern. Little is known about this snail of sandbars and edges of the Kern River. The last known collection of the Kern shoulderband is from a 1939 literature citation noting a collection from dead vegetation on the river's edge. This species was not observed during the field surveys. The Kern River represents a historic habitat for the southwestern pond turtle (Clem~nys marmorata pallida); although their occurrence is considered unlikely but possible, they were not observed on the project site. The southwestem pond turtle frequents streams, rivers, ponds, lakes, and marshes. Dense cover and exposed basking sites are key components to suitable southwestern pond turtle habitat, with deeper, slow pools being preferred. Although the lower Kern River and adjacent marshes and sloughs historically supported southwestern pond turtles, they are currently considered to be infrequent along this portion of the river. California horned lizard (Phrynosoma coronatum) is a flat bodied lizard that is up to 6 inches in length. It has a large crown of spines on the posterior portion of its head. The cranial spines of the California homed lizard tend to be similar in size, whereas the central two spines tend to be longer in the other subspecies. There are large dark spots on the side of its neck and there are two rows of pointed scales at the fringe of its trunk. Coloration is reddish, brown, yellow, or gray with dark blotches on the back; coloration is variable and is possibly dependent upon soil coloration. This lizard lays a clutch of 6 to 12 eggs in May or June, and hatchlings emerge in July or September. Their main food source is ants. This lizard is diurnal and will inflate with air when frightened to avoid predation. Other defensive strategies include threatening would-be enemies with an open mouth and hissing noises, tilting its head to expose the cranial spines, biting, and spraying blood from the comer of its eyes. The California homed lizard occurs along the coast north of San Francisco Bay to Los Angeles, and inland into the Sacramento ay4. San Joaquin valleys. It inhabits open areas of sandy soil with low sparse vegetation. This species was not observed during the field surveys. Cooper's hawk (Accipiter cooperi) is a medium-sized hawk (length = 14-20 inches; wing = span 29-37 inches) and is mostly brown above, with the male being more bluish above and more heavily marked (barred) below. The tail is strongly barred on the underside. Juveniles are lighter below, with fine streaks in the chest area. As in most raptors, the female is substantially larger than the male (app 1/4 to 1/3 larger). The long tail and short, rounded wings are characteristic of the genus Accipiter. Also 02160007.EIR. doc V. 2-1 4 Biological Resources Northeast Bakersfield Bike Path and Water Facilities - Draft EIR diagnostic of the genus is the flight profile, which consists of a series of strong, rapid beats followed by a glide. Cooper's hawks can be confused with the similar but smaller sharp-shinned hawk, as these two species have similar coloration and body proportions. However, the larger size, proportionately larger head, more distinaive black cap, and longer, more rounded tail distinguishes the Cooper's hawk. This species was not observed during the field surveys. Sharp-shinned hawk (Accipiter striatus) are similar in appearance to Cooper's hawks, but smaller. Their diet consists primarily of birds. In the project area, riparian woodlands provide suitable habitat for this species. This species was not observed during the field surveys. Golden eagle (Aquila chrysaetos) is a large, brown raptor (length = 30-40 inches; wing span = 80-88 inches) that, in the western states, occurs primarily in open, mountainous areas, foothills, canyons, and plains. Large size and flat-winged soaring distinguish the golden eagle from large hawks. Immature golden eagles may be distinguished from immature bald eagles by their thinner bills and relatively smaller heads. In flight, as viewed from below, immature golden eagles show more clearly defined white patches at the base of the primaries and also a distinctive white tail with a dark terminal band. The golden eagle is a circumpolar species that occurs over much of the United States and southern Canada. In the western United States, it is a year-round resident. Nesting occurs in trees and on cl'iff faces. Their diet consists primarily of mammals (mostly lagomorphs and ground squirrels), birds, and snakes. This species was not observed during the field surveys. A burrowing owl (Athene cunicularia) was observed along the proposed bike path and water pipeline alignment along Paladino Drive. During the nesting season, the burrowing owl often perches on a low post or at the entrance to a burrow. Burrowing owls inhabit dry, open grasslands, rolling hills, desert floors, prairies, savannas, agricultural land, and other areas of open, bare ground. These owls will also inhabit open areas near human habitation, such as airports, golf courses, shoulders of roads, railroad embankments, and the banks of irrigation ditches and reservoirs. Resident burrowing owls begin pair formation as early as December, and migratory birds begin upon their amval in the breeding area, usually in March and April. Nests are generally located in bare, level ground in abandoned mammal burrows. Northern harrier (Circus cyaneus) is a medium-sized (length = 1%24 inches; wing span = 38-48 inches), relatively slender hawk that is most easily recognized by its conspicuous white romp. Wings are comparatively long, as in falcons, but are more rounded. This raptor is unusual in that sexual dichromatism is pronounced: females are mostly brown above and white with brown streaks below, whereas males are generally grayish above, white below, and the wing tips are black. Also diagnostic o2 ~6o0o'~.Em. aoc V.2-15 Biological Resources Northeast BakersfieM Bike Path and Water Facilities - Draft EIR is the erratic flight of leisurely wing beats and swift glides, usually low to the ground, and with wing tips up-tamed. Harriers also often perch close to the ground. Northem harriers range throughout North America, and in California they are usually year-round residents (some southern California birds may be over-winter visitors). Formerly known as the marsh hawk, these birds primarily inhabit marshes, fields, and prairies. Diet consists primarily of small rodents, though frogs, reptiles, and insects are also taken. This species was not observed during the field surveys. Several loggerhead shrikes (Lanius ludovicianus) were observed in many areas of the project site. This shrike occurs over most of the U.S., Mexico, and central Canada. In California, the shrike occurs as a resident over most of the state, being absent from high mountain regions. Habitat consists of open areas, such as savannas and deserts, where bushes, small trees, or other perch sites are available. Diet includes a variety of insects and spiders, small reptiles, rodents, and small birds (Ehrlich et al 1988). Several potential short-nosed kangaroO rat (Dipodomys nitrate'des brevinasus) burrows were observed in the bank of the existing bike path north of the soccer park. No diagnostic kangaroo rat sign (scat, tracks, tail drags) was observed at these burrows. However, in some places, the soil was so coarse that tracks and tail drags were difficult to detect. The short-nosed kangaroo rat is a small species of the genus Dipodomys, measuring up to 9 inches in total length. It is one of three recognized subspecies of the San Joaquin kangaroo rat (Dipodomys mtratoides). Short-nosed kangaroo rats excavate shallow burrows from which animals emerge at night to forage for seeds. Short-nosed kangaroo rats are generally found on flat and gently sloping terrain and on hill tops in scrub vegetation (primarily saltbush). They are found on friable, sometimes alkaline soils. Light to moderate grazing by livestock probably enhances habitat for short-nosed kangaroo rats (Williams 1986). Short-nosed kangaroo rats are found on the western side of the San Joaquin Valley, from near Los Banos, Merced County, southwest of the San Joaquin River in a line approximately coincident with the Kettleman Hills, Lost Hills, and Elk Hills of the southern end of the Valley. They also occur in the Panoche Valley, San Benito County, the Sunflower Valley, Kings County, the Antelope Plain in Kern County, the Cardzo Plain in San Luis Obispo County, the Cuyama Valley in San Luis Obispo and Santa Barbara counties, and at the edge of the valley floor around the southern end of the San Joaquin Valley from the vicinity of Maricopa on the west, to east of Bakersfield on the east. American badger (Taxidea taxus) are low, squat animals with conspicuous silver-tipped pelage dorsally and a short black-tipped tail. The most striking visual feature of this species is its striped face, consisting of a median white stripe proceeding from the tip of its nose to the back of its head. 02160007.EIR. doc V. 2-1 6 Biological Resources Northeast BakersfieM Bike Path and Water Facilia'es - Draft EIR This stripe is flanked by alternative white and dark stripes giving way to bright, white-outlined ears. The badger's wide flattened body is supported by short but powerful legs. The front feet are fitted with noticeably long claws that are especially well-suited for digging out the burrows of the rodents on which it feeds. Historically, badgers are thought to have been fairly widespread in the open grassland habitats of the lower San Joaquin Valley. Their modem San Joaquin Valley distribution is essentially restricted to the limited often isolated and remote tracts of native grassland and shrubland habitats..Cultivated lands have been reported to provide little usable habitat for this species, and badgers are believed to be declining throughout California (Williams 1986). Badgers are solitary animals. They usually forage for burrowing prey such as gophers, ground squirrels, marmots, and kangaroo rats, although they are known to take a variety of nesting mammals, reptiles, and birds. This species was not observed during the field surveys. Aquatic wildlife of the Kern River near the project consists primarily of several common introduced and some native amphibians and fish such as Pacific tree frog (Hyla regilla), bullfrog (Bufo boreas), rainbow trout (Oncorhynchus mykiss), smallmouth bass (Micropterus punctualatus), largemouth bass (bticropterus salmoides), and common carp (Cyprinus carpio). Although existing survey data is minimal, native fish which are likely to occur along this portion of the Kern River include hardhead (Mylopharodon conocephalus) and Sacramento squawfish (Ptychocheilus grandis). Wildlife Movement Corridors The Kern River is a wildlife movement comdor that is used by a variety of wildlife species. The comdor is approximately 500 feet wide; however due to existing structures (i.e., CALM and Alfred Harrel Highway) and a narrow riparian zone, the corridor is approximately 50 feet wide in the vicinity of the project site. This existing corridor restriction affects access and use by large land mammals. V.2.2 PROJECT IMPACTS Thresholds of Significance Appendix G of the CEQA Guidelines states that impacts to biological resources due to project implementation are considered significant if the project may have one or more particular adverse effects, including: · Substantially affecting an endangered or threatened species of plant or animal ~or that habitat of that species. 02160007.EtR. doc V.2-17 Blological Resources Northeast Bakersfield Bike Path and Water Facilities - Draft EIR · Substantially diminishing habitat for fish, wildlife or plants. · Interefing substantially with the movement of any resident or migratory fish or wildlife species. Direct Impacts Special Status Species Included in the MBHCP '°Take" of listed threatened and/or endangered species may occur in association with all components of project construction, operation, only species likely to occur during the and maintenance. The listed in the vicinity of all project components is San Joaquin kit lox and blunt-nosed leopard lizard. One San Joaquin kit fox suspected pupping den and two known dens may be impacted by construction of the bike path along Paladino Drive, near its intersection with Fairfax Drive. Potential kit fox dens may be impacted by all components of the project. Destruction or disturbance to burrows or dens could displace threatened and endangered species into adjacent areas which are either unsuitable or already occupied. Individuals could be crushed in burrows within the construction area. An increase in vehicle traffic and access to offroad areas in the project area would expose wildlife to an increased probability of vehicular mortality. Other special status species which may occur within the project area which are also covered under the MBHCP include short-nosed kangaroo rat and San Joaquin pocket mouse. Based on survey observations, short-nosed kangaroo rat may occur along the Hart Memorial Park conveyance pipeline, but is unlikely to occur on other project component areas. The San Joaquin pocket mouse may occur at all of the project component areas. One individual clump of Bakersfield cactus could be impacted by construction of the water pipeline south of the pond. Two areas consisting of about 10 clumps of Bakersfield cactus could be impacted by construction of a portion of the bike path between Alfred Harrell Highway and Paladino Drive, the water treatment plant access road and adjacent pipeline. Except for the area between the bike path and water treatment plant site, the pipeline between Alfred Harrell Highway and Paladino Drive and the access road follow the bike path alignment in this location. The remaining project components are not anticipated to impact Bakersfield cactus. No other impacts to listed plant species are anticipated. Impacts to Bakersfield cactus would be potentially significant. Special Status Species not Included in the MBHCP Although not observed, Valley elderberry longhorn beetle may also be present on elderberry shrubs observed within the survey area only along the Hart Memorial Park conveyance pipeline. Disturbance, 02160007. EI1Ldoc V. 2 - 18 Biological Resources I Northeast BakersfieM Bike Path and Water Facilities - Draft EIR including destruction of shrubs and trimming, could result in "take" of Valley elderberry longhorn beetles. Elderbemes were not present in association with other project components. Although suitable: nest trees for Swainson's hawk are present near the intake structure, pond, and along the Hart Memorial Park conveyance pipeline, the intensity of human activity in the immediate .1 area of the project site makes it unlikely that this species would utilize these sites. However, if a '-' Swainson's hawk nest were to occur in the project ar~a, project activities could disturb the individuals and possibly cause the nest to be abandoned. Suitable nesting habitat for Swainson's hawk was not observed along any portion of the bike path or any other water facilities project components. .. , i Other upland special status species which are likely to occur in the project area would be subject to the ~-~ same potential direct impacts as listed species. Species which were observed during surveys or are · likely to occur within the project area include Cooper's hawk, sharp-shinned hawk, burrowing owl, golden eagle, northern harrier, prairie falcon, and loggerhead shrike. Impacts to these species I could occur as a result of all project components. Aquatic species could be impacted by construction and operation of the intake structure and low lift · station. Species of concern which potentially occur in the Kern River which may be affected include southwestern pond turtle, Kern brook lamprey, and hardhead. Kern brook lamprey are very small and would be difficult to exclude from the intake. Additionally, it is fairly unlikely that they 1 occur in the Kern iRiver adjacent to the intake structure. If southwestern pond turtle and/or hardhead occur in the Kern River adjacent to the intake, individuals could be injured or killed if they entered the 1 intake structure and lift station. Although the intake is designed for gravity flow (no suction), these species would not be precluded from entering the intake structure. Impacts to these species would be potentially significant. Other special status species not included in the MBHCP which are unlikely to be impacted due to the small amount of suitable habitat or probable infrequent use of the site vicinity include, Kern shoulderband, LeConte's thrasher, and osprey. Of the unlisted special status plant species potentially occurring in the vicinity of the project, only cottony buckwheat was observed. The population of this species was observed in the buffer area ,/~ 1 during the survey and is unlikely to be impacted. Breeding Birds 1 All project components contain habitat elements which potentially support breeding birds, their nest and young. Riparian habitats are particularly sensitive in terms of breeding bird use. However, species such as burrowing owls use burrows in grassland habitats and several ground-nesters, such as western i 02 ~6ooo,.£m. ao~ V.2-19 Biological Resources I' ! Northeast Bakersfield Bike Path and Water Facilit~'es - Draft E1R meadowlark, use this habitat type as well. If project construction occurs during bird nesting season i (for most species, March 15 through July 31), nests, eggs, and/or young of species protected by the Migratory Bird Treaty Act could be disturbed, in violation of this statute. i,! Vegetation i Project-related impacts which may result in disturbance to the vegetation communities found during , the project surveys is shown in Table V.2-3. Habitat loss through conversion to agricultural, urban, and oilfield uses is the primary reason for the listing of threatened and endangered species of the southern San Joaquin Valley. Although habitat will recover from short-term impacts, during the time of recovery, the habitat will I I not be able to support the same density and diversity of species which were supported prior to the disturbance. This is especially true of riparian habitat, where various plant species in the understory l' and overstory combine to provide complex habitat qualities. Higher quality riparian habitat is used extensively by nesting birds. In addition, snags, dying trees, and trees with cavities provide necessary nesting, roosting, and other resources for certain species. Several cottonwoods, willows, and other riparian trees were observed within the riparian vegetation I along the Hart Memorial Park conveyance pipeline and at the intake structure. Although impacts to individual trees cannot be identified until construction plans are finalized, some of these trees may be removed or trimmed during construction activities. i Construction of the intake structure and turnout could additionally impact wetland habitat at the fringe I of the Kern River. Although wetland plant species were observed along the fringe of the river, the jurisdictional status of this area has not been determined. If any of the area near the intake structure is - subject to ACOE jurisdiction, a wetland delineation would be necessary to determine whether or not i wetlands meeting jurisdictional criteria are present and the extent of those wetlands. Short- and long-term impacts to vegetation would be significant. l I i 02160007.EIR. doc V.2-20 Biological Resources I Northeast Bakersfield Bike Path and Water Facilities - Draft EIR TABLE V.2-3 SHORT- AND LONG-TERM IMPACTS TO VEGETATION COMMUNITIES Bike Path Alfred Harrell Hwy to Paladino Dr 7.7 3.1 10.8 2.2 0.9 3.1 Along Paladino Dr 12.5 t2.5 3.6 - 3.6 Total Bike Path 20.2 3.1 23.3 5.8 0.9 - 6.7 Water Facilities Intake and Low Lift Station - 5.0 5.0 - 5.0 5.0 Ponds, High Lift Station, and Turnout 15.0 - 15.0 15.0 15.0 Hart Memorial Park Conveyance~ 1.23 0.6 1.8 ....

These areas would be impacted by construction of the intake structure, low lift station, and the Hart Memorial Park conveyance pipeline. Construction adjacent to the Kern River 02160007.EIR. doc V.2:2 1 B~ologlcal Resources Nor&east BakersfieM Bike Pa& and Water Facilities - Draft EIR could increase sedimentation resulting from stormwater runoff over unvegetated surfaces. In addition, although no riparian vegetation is present, areas potentially regulated by ACOE and CDFG within the unnamed blueline stream south of Alfred Harrell Highway would be impacted by project activities. Project impacts to the blueline stream south of Alfred Harrell Highway and the area within the 100- year floodplain of the Kern River would be potentially significant. Kern River Wildlife Corridor Construction of facilities associated with the Hart Memorial Park conveyance pipeline, pond, intake structure and low lift station would temporarily disturb habitat and displace resident wildlife. Habitat disturbance associated with construction along the Kern River corridor would be a potentially significant impact. However, none of the project components will result in permanent facilities which would obstruct the wildlife corridor. The proposed pond would narrow the corridor of open space to approximately 300 feet at the closest point to the river. However, the pond location is outside of the existing riparian zone in non-native grassland, which provides relatively low habitat value and minimal cover for wildlife along this corridor. Due to existing corridor restriction from CALM, Alfred Harrell Highway, and a narrow riparian zone, the. implementation of the proposed pond outside of the existing riparian zone would not significantly affect the existing wildlife movement corridor. Indirect Impacts Offsite Habitat Degradation Increased human activity along the bike path, and water facilities is likely to result in degradation of adjacent habitat. Adjacent riparian habitats are likely to experience a greater impact from increase access than grassland or scrub habitats. Increase litter, noise, and the vegetation trampling, potential for wildlife harassment are likely to occur. Maintenance of vegetation free areas adjacent to facilities favors introduction of alien plant species into these and adjacent areas. Iandscaping of the pond area could result in introduction of invasive alien plant species to the Kern rover corridor, decreasing the habitat quality for native species. These impacts would be potentially significant. ! i 02160007.EIR.doc V.2-22 Biological Resources ! Nor&east Bakersfield Bike Path and Water Facilities - Draft E1R V.2.3 CUMULATIVE IMPACTS Implementation of the proposed project and the related projects would contribute to a cumulative loss of non-native grassland, saltbrush scrub, and riparian habitats that support sensitive plant and wildlife species endemic to the southern San Joaquin Valley. Except for a portion of the project site along the Kern River, all areas of the proposed project and related projects are located within the limits of the MBHCP. Compensation for habitat loss through the MBHCP would reduce these impacts. The MBHCP does not cover areas along the Kern River. The related projects identified in Section IV are not located along the Kern River and are located in areas that are included in the MBHCP. There'fore, the portion of the proposed project adjacent to the Kern River is not expected to contribute to cumulative impacts since the related projects would not impact riparian habitat outside of the MBHCP. The proposed project includes mitigation measures to reduce impacts on riparian habitat and associated species that are located outside the MBHCP. Therefore, the proposed project would not contribute to significant cumulative biological impacts. V.2.4 MITIGATION MEASURES Direct Impacts Special Status Species included in the MBHCP With the exception of the area within the 100-year floodplain of the Kern River, the proposed project area is within the plan area for the Metropolitan Bakersfield Habitat Conservation Plan (MBHCP). Therefore, for upland species included within the MBHCP, primary mitigation would consist of participation in this program through compensation for habitat disturbance and implementation of take avoidance measures. The following shall be implemented. BR-1. Prior to the issuance of a grading permit and/or approval of plans and specifications, the project proponent shall pay a development fee in accordance with the Metropolitan Bakersfield Conservation Plan. BR-2. Prior to the issuance of a grading permit and/or approval of plans and specifications, the project proponent shall comply with all appropriate terms and conditions of the MBHCP. The MBHCP requires certain take avoidances for the Bakersfield cactus and San Joaquin kit fox. MBHCP guidelines regarding tracking and excavation shall be followed to prevent entrapment of kit fox in dens. Specific measures during the construction phase of the project shall be implemented and include the following: a. A preconstruction survey shall be conducted prior to site grading (not more than 30 days from the onset of construction activities) to determine the necessity of relocating Bakersfield cactus and searching for active kit fox dens. o216oooT.Em, ao¢ V..2-23 Biological Resources Nor&east BakersfieM Bike Pa& and Water Facilities - Draft E1R b. If Bakersfield cactus is located on the project site, CDFG and USFWS shall be notified of the need for relocation. After approval by CDFG and USFWS, a qualified biologist/bontanist shall relocate the plant species. c. If an active kit fOx den is located on the project site, CDFG and USFWS shall be notified of the need to excavate the den. After approval by CDFG and USFWS, a qualified biologist shall supervise the excavation of the den. d. All pipes, culverts, or similar structures with a diameter greater than 4 inches shall be capped or blocked to prevent entry by San Joaquin kit fox and other wildlife. If pipe is not capped (i.e. short pipe segments stockpiled prior to use), it should be inspected for kit fox. If any kit fox are observed within pipe, they shall be allowed to escape unimpeded; e. All trenches or steep-walled excavations greater than three feet deep shall include to allow wildlife to Each excavation shall contain at least one escape ramps escape. ramp, with long trenches containing at least one ramp every 1/4 mile. Slope of ramps shall be no steeper than 1:1; f. All employees, contractors, or other persons involved in the construction of the project shall attend a "tailgate" session informing them of the biological resource protection measures which will be implemented for the project. The orientation shall be conducted by a qualified biologist and shall include information regarding the life history of the protected species, reasons for special status, a summary of applicable environmental law, and measures intended to reduce impacts. For any portion of the project area within the 100-year floodplain of the Kern River, a request shall be submitted to the MBHCP Implementation Trust Group to allow for compensation for habitat disturbance through the plan. The Implementation Trust Group can allow projects within the 100-year floodplain to participate in the MBHCP at their discretion. This MBHCP covers the following listed species which have been identified as being potentially impacted by the proposed project: blunt-nosed leopard lizard, San Joaquin kit fox, and Bakersfield cactus. Based on the broad, ecosystem-based approach of the MBHCP, compensation through participation in this plan would be sufficient to mitigate for loss of habitat for other potentially occurring upland non-listed special status species potentially occupying the project area. Participation in the MBHCP would not sufficiently mitigate for impacts to the following potentially affected special status species: Valley elderberry longhorn beetle, hardhead, southwestern pond turtle, and Swainson's hawk. ! 02160007.EIR. doc V.2-24 Biological Resources I Northeast BakersfieM Bike Path and Water Facilities - Draft EIR Special, Status Species not included in the MBHCP Valley elderberry longhorn beetle, southwestern pond turtle, and Swainson's hawk are primarily riparian-associated species which were not included in the MBHCP. The following measures shall be implemented to avoid impacts to these species: BR-3. Prior to the issuance of a grading permit and/or approval of plans and specifications, the project proponent shall demonstrate that Elderberry shrubs will not be destroyed, trimmed, or otherwise impacted to avoid the potential for "take" of Valley elderberry longhorn beetle. If elderberry shrubs cannot be avoided, a directed survey for the beetle shall be conducted. If this species is found, the project applicant shall obtain a Section 10(a) pemit from USFWS. BR-4. Prior to the issuance of a grading permit and/or approval of plans and specifications, a preconstruction survey of Swainson's hawks shall be conducted. If Swainson's hawks are found nesting on the project site, no construction activities shall occur until a CDFG- approved biologist has determined that the young in the nests have fledged. BR-5. Prior to the issuance of a grading permit and/or approval of plans and specifications, a preconstruction survey of southwestern pond turtles shall be conducted. If southwestern pond turtles are found on the project site, USFWS and CDFG shall be contacted. After approval by USFWS and CDFG, a qualified biologist shall relocate the species. BR-6. Prior to the issuance a grading permit, the City shall demonstrate to the County that the intake structure is designed to include screening that would prevent the southwestern pond turtle and hardhead from entering the intake structure. Breeding Birds Native bird and raptor nests are protected under the Migratory Bird Treaty Act. If possible, all site grading and activities which could directly impact riparian vegetation should be conducted between August 1 and March 14, during the non-breeding season for most bird species. If these activities must be conducted during the breeding season (March 15 through July 31), a biologist should survey the vegetation for bird nests prior to grading. If no active bird nests are located, grading in areas where no active nests are present could occur during breeding season. The following measure will be implemented to reduce potential impacts to native birds and raptors: BR-7. In compliance with Sections 3503 and 3503.5 of the California Fish and Game Code, if grading is to occur during the native bird and raptor nesting breeding season (March 15 through July 31), a qualified biologist shall determine the presence of any native bird and raptor nests prior to or concurrent with grading activities. In addition, CDFG will be contacted to obtain and comply with all appropriate procedures relative to grading operations in proximity to any active nests identified. Resulting mitigation measures may include restricting construction activities near native bird and raptor nesting sites during and immediately following the breeding season. 02160007.EIR. doc V.2-25 Biological Resources Northeast BakersfteM Bike Path and Water Facilities - Draft E1R Vegetation Potential impacts associated with riparian habitat would be reduced through the implementation of Mitigation Measure BR-13 for riparian habitat within jurisdictional streambeds and/or wetlands and through the following measures for riparian habitat that is located outside of jurisdictional streambeds and/or wetlands. BR-8. Prior to the issuance of a grading permit and/or approval of plans and specifications, the project proponent shall demonstrate that construction within 50 feet of the dripline of Fremont cottonwoods and sycamores will be avoided, to the maximum extent possible. Buffer for trees to be avoided shall be clearly marked with caution tape or similar zones material. If any of these species cannot be avoided, individuals over 3 inches diameter breast height should be replaced on or adjacent to the site at a 3:1 ratio for each tree impacted. BR-9. Prior to approval of plans and specifications, the County of Kern shall demonstrate that riparian scrub habitat disturbed as a result of constructing the Hart Memorial Park conveyance pipeline will be allowed to regenerate onsite. BR-10. Prior to the issuance of a grading permit and/or approval of plans and specifications, a Riparian Habitat Mitigation Plan shall be prepared by a qualified revegetation specialist and submitted for approval to the City or County depending on the location of the impact. BR-11. At a minimum, the Riparian Habitat Mitigation Plan shall identify trees to be removed and anticipated riparian scrub habitat disturbance, monitoring plan, and success criteria. The minimum monitoring period shall be not less than 5 years to determine replacement and revegetation success. BR-12. Prior to the issuance of a grading permit and/or approval of plans and specifications, sik fencing or other suitable methods shall be employed to prevent erosion of exposed construction surfaces into the Kern River or adjacent riparian habitats. Rivers and Drainages A formal streambed and wetlands delineation will be conducted onsite to determine the extent of impacts to areas that fall within the jurisdiction of CDFG and ACOE. Subsequent to the formal delineation, the following mitigation measure will be implemented to reduce potential impacts to jurisdiction streambeds and wetlands to a less than significant level: BR-13. Prior to the issuance of a grading permit and/or approval of plans and specifications, there will be a determination as to whether the proposed project could potentially affect jurisdictional streambeds and/or wetlands. If there is a potential to affect streambeds and wetlands, California Fish and Game Code, Section 1601 Streambed Alteration Agreement and/or a Clean Water Act permit from ACOE will be obtained from CDFG and/or ACOE, respectively. The CDFG and ACOE typically require mitigation plans to be prepared prior to the loss of habitat within streambeds and wetlands. Mitigation may consist of habitat replacement at a ratio of 1:1 or greater for each acre lost through project implementation. 02160007.EIR. doc V.2-26 Biological Resources Northeast Bakersfield Bike Path and Water Facilities - Draft E1R Kern River Wildlife Corridor Mitigation measures for impacts associated with vegetation disturbance along this corridor are addressed in Mitigation Measures BR-8 through BR-13. No further mitigation measures are necessary to address the potential project impacts along the Kern River wildlife corridor. Indirect Impacts Offsite Habitat Degradation BR-14. During construction, site boundaries shall be clearly marked with flagging, fencing, or other suitable material to prevent construction equipment and vehicles from impacting adjacent habitat areas potentially occupied by special status species. BR-15. All trash and food waste shall be disposed of in closed containers and regularly removed from the project construction site and completed bike path. No deliberate feeding of wildlife will be allowed. BR-16. Information kiosks shall be provided at parking areas for the bike path which contain information regarding sensitive biological resources present along the bike path and general vicinity. Prior to posting, the information presented shall be approved by CDFG and USFWS. BR-17. If the proposed pond or water treatment plant are landscaped, a landscape architect familiar with native plant material and knowledgeable regarding invasive exotic plants shall be retained to at least review landscape plans. Among others, the following invasive exotic plants shall not be used in any project landscaping: tamarisk (all species), pampas grass, water hyacinth, or castor bean. In addition, vegetation on the ponds shall be managed in a way such that none of the invasive exotic plants listed above is allowed to become established. V.2.5 SIGNIFICANCE OF IMPACTS AFTER MITIGATION Implementation of the mitigation measures identified above will reduce potential project impacts to identified biological resources to less than significant levels. 1 02160007.EIR. doc V.2-27 Biological Resources i Northeast BakersfieM Bike Path and Water Facilit~'es - Draft EIR V.3 LAND USE V.3.1 EXISTING CONDITIONS Onsite and Surrounding Land Uses The project site is located in the northeast Bakersfield area that is primarily undeveloped.

Several local and regional plans and programs apply to development on. and surrounding the project site. Metropolitan Bakersfield 2010 General Plan The Metropolitan Bakersfield 2010 General Plan is composed of elements which address a broad and evolving range ot' issues. Each element of the plan identifies and describes goals, policies, and implementing actions that provide direction for decision-making and formulation of public policy. The General Plan contains the seven elements required by State law and four optional elements that correspond to the development of the Bakersfield metropolitan area. The most relevant goals, policies, and implementation actions as they relate to the development of the project site are found in the land use, circulation, conservation, open space, and Kern River Plan elements of the General Plan. Following is a discussion of the relevant elements and applicable goals, policies, and implementation actions. Land Use Element The Land Use Element provides long-term guidance for the development and use of land within the Metropolitan Bakersfield area. The current General Plan land use designations of the project site include public and private recreational areas with an overlay of flood hazard north of Alfred Harrell Highway. The designations of the project site south of Alfred Harrell Highway include open space, low residential, general commercial, and mineral petroleum. The Land Use Element includes the following three policies that are related to the proposed project: · Policy 42: Provide for the establishment of the following new major centers as the focus of development in the planning area: ... c) Northeast. · Policy 45: Allow for the development of a low density "village-like" center in the Northeast as a focal point of activity ......

The Open Space Element contains the following policies that are related to the proposed project: · Policy 4: Require the use of grading techniques in hillside areas which preserve the form of natural topography and ridgelines. · Policy5: Development location and siting should be sensitive to its relationship to the Kern River. Kern River Plan Element The purpose of the Kern River Plan Element is to provide public access to the Kern River for recreation and to provide for the preservation of native plants, wildlife, and cultural resources while providing for the protection of private property rights. The following policies in the Kern River Plan Element relate to the proposed project: · Policy 3.1.3-1: Public parks, beaches, foot access, riding and hiking trails, and bicycle paths are intended to be developed and maintained in areas as shown on the Kern River Plan Map subject to the provisions of this plan. · Policy 3.2.3-3: Buildings, structures, and vegetation shall be constructed, installed or planted in a manner to minimize to the greatest extent possible, the obstruction of scenic views of the Kern River from highways, streets, trails, parks or beach areas. · Policy 3.2.3-6: Grading or earthmoving for projects within the secondary floodway shall blend with the existing topography, and vegetation shall subsequently be harmoniously reestablished where it ,!.:es not conflict with channel maintenance and recharge facilities. · Policy 3.3.2-6: The placement of structures and other related accessory uses shall respect wildlife corridors and shall no obstruct nor hinder the movement or migration of wildlife. 02160007.EllLdoc V.3-4 Zand Use Nor&east BakersfteM Bike Pa& and Water Facilities - Draft EIR ,! i ' Zoning The portion of the project site that is located north of Alfred Harrell Highway is within a Recreational Forestry (RF) District under the County of Kern Zoning Ordinance. The RF District allows both I "large water systems" and "water storage and groundwater recharge facilities" as permitted uses. i The portion of the project site that is located south of Alfred Harrell Highway is primarily One Family Dwelling Zone (R-l) with two small areas designated for commercial (C-2). The water treatment plant site is currently zoned for agriculture (A). California Land Conservation Act (Williamson Act) Based on a review of the Williamson Act contract for the water treatment plant site, the contract was not renewed in 1982, and therefore, since 1992, no contract existed on the water treatment plant site. Other portions of the project site are also not within a Williamson Act contract. According to the Metropolitan Bakersfield General Plan, no area of the project site is classified as prime farmland. I V.3.2 PROJECT IMPACTS The development of the proposed project will result in environmental effects in the area that are affected by and affect land use compatibility. These relate to aesthetics, air quality, noise, etc. These impacts, although related to land usc, are addressed in individual sections of this EIR. This section focuses on impacts to onsite and surrounding land uses, and impacts to land use-related planning programs resulting from the implementation of the proposed project. Thresholds of Significance The proposed project will result in a significant impact on the environment related to land use issues if: · Compatibility conflicts between onsite and/or offsite land uses are created; · The project results in the removal of prime farmland from production. In addition, the project would have a significant impact on agricultural resources if it resulted in the early removal of agricultural land from agricultural preserve status; · The project substantially reduces the amount of available open space in the region; The project is inconsistent with the goals, policies or implementation actions of any local, state, or federal plan or program. 02160007.EIR. doc V.3-5 Land Use Northeast BakersfieM Bike Path and Water Facdit~'es - Draft EIR Land Use Compatibility Implementation of the proposed project would allow for the development of a bike path and water facilities, including the intake structure, low lift pump station, raw water pond, Hart Memorial Park turnout and conveyance pipeline, high lift pump station, water treatment plant, and water pipelines. The use of the bike path will be a non-intensive use and will be compatible with the surrounding open space, residential, and oil facility uses. The proposed bike path will connect with the existing bike path along Fairfax Road and along Alfred Harrell Highway. The water facilities proposed north of Alfred Harrell Highway would be generally compatible with the surrounding uses (Kern County Soccer Park, CALM, and the Camp Okihi Group Site and residence on the north side of the Kern River). The largest proposed water feature north of Alfred Harrell Highway is the raw water pond. The presence of the pond near the Kern River would be visually compatible with the surrounding uses. ImPlementation of the proposed water treatment plant would also result in not significant aesthetic and visual impacts and would be compatible with the surroun~ng uses, including the adjacent residences. Consistency with Plans~ Policies~ and Programs Metropolitan Bakersfield 2010 General Plan Land Use Element Implementation of the proposed project would be inconsistent with the existing land use designation for the water treatment plant site. Implementation of the proposed project would require a General Plan amendment. The proposed site for the development of the water treatment plant is designated for low-density residential (LR) development in the General Plan. The proposed General Plan amendment would change the land use designation of the water treatment plant site to public facility (P). With the implementation of the proposed project, the Land Use Element in the General Plan would need to be amended to reflect the type of-development proposed on the project site and, therefore, Would be consistent with the land uses proposed under the project. Development of the proposed facilities would be generally consistent with other policies of the Land Use Element. As depicted on the General Plan land use map, growth that would be associated with project induced development would be consistent with the applicable policies in the Land Use Element (i.e. Policies 42 and 45). The proposed project would also support Policy 62 by developing an activity 02 ! 60007.UlR. doc V. 3-6 Zand Use Northeast BakersfieM Bike Path and Water Facilities - Draft EIR corridor and developing recreational activities through the construction of the bike path; linking the existing residents of northeast Bakersfield to the Kern River and Hart Memorial Park. Circulation Element The project would achieve consistency with the objectives of the Circulation Element of the General Plan through the incorporation of the bike path as discussed in the Bikeway Master Plan. Furthermore, by partially funding the project through a federal grant, one of the implementation actions of the General Plan is fulfilled. The bike path would achieve consistency with the General Plan by fulfilling of its goals and one of its implementation actions (see Goal 3 and one Implementation 10). Therefore, the implementation of the proposed project is consistent with the Circulation Element. Conservation Element The proposed project is consistent with the objectives of the Conservation Element of the General Plan through fulfillment of several of its policies, goals, and implementation actions. Implementation of the proposed project would result in augmentation of water resources and ensuring adequate water supplies to the northeast Bakersfield planning area (see Goals 1 and 3, and Policy 4). Furthermore, the project is an effort towards decreasing the groundwater deficiencies in the upland portions of the planning area (see Policy 5). The City of Bakersfield's 2800-acre water spreading basin would be maintained and the burden to other water sources would be alleviated with the implementation of the proposed project (see Implementations I and 8). Open Space Element The Open Space Element of the General Plan requires any new development to preserve the natural topographic form of the landscape and take into account its relationship with the Kern River (see Policies 4 and 5). The proposed water treatment plant will be constructed in a manner consistent with Policy 4 by preserving the natural topography of its landscape. The proposed intake structure as well as the connection of the Hart Memorial Park conveyance pipeline to the unlined canal is intended to be designed to reduce potential impacts on the Kern River and be consistent with Policy 5. The implementation of the project will allow the removal of the existing CALM, Kern County Soccer Park, and the Hart Memorial Park intake pipes and pump stations along the Kern River; thereby, reducing potential impacts. Furthermore, the proposed project will allow the County to adverse visual eliminate the need to periodically replace the diversion dam within the Kern River. The water diversion dam could be allowed to wash away after project implementation. 02160007. EIR.doc V.3-7 Land Use Northeast Bakersfield Bike Path and Water Facilities - Draft EIR Through maintaining consistency with the policies mentioned above, the proposed project will be consistent with the Open Space Element of the General Plan. Kern River Plan Element The proposed project is consistent with the Kern River Plan Element of the General Plan by fulfilling several of its policies. The development of the bike path and the continuance of the hiking and tiding trail along the Kern River is consistent with the Kern River Plan Map and its associated policies (see Policy 3.1.3-1). Views from Alfred-Harrell Highway, the hiking and horseback riding trail, CALM, Kern County Soccer Park and the Boy Scout park will be considered in the siting and construction of the proposed project. Structures will be painted with earth tones and native vegetation will be used in the landscaping to help blend the structures with their surrounding natural environment (see Policies 3.2.3-3, and 3.2.3-6). The implementation of the proposed intake structure, low lift station, pond, and Hart Park Memorial Park conveyance pipeline is not anticipated to affect the existing wildlife comdor along the south side of the Kern River. Therefore, the project would be consistent with Policy 3.3.2-6. Zonin~ Except for the proposed water treatment plant, all of the project facilities are permitted within the onsite zoning designations. The proposed water treatment plant site is ioned for agriculture. A water treatment plant is considered a conditional use within an agriculture zone. The proposed project includes a request for a conditional use permit. After approval, the project would be considered consistent with the zoning ordinance. California Land Conservation Act (Williamson Act) Since the project site does not include any areas that are under a Williamson Act contract or are classified as prime farmland, the implementation of the proposed project would not result in impacts to farmlands. V.3.3 CUMULATIVE IMPACTS Development of the proposed project and related projects would represent an increase level of development and intensification in the northeast Bakersfield area. Each project is subject to separate by City or County staff for conformance with applicable development environmental review regulations, to minimize the direct impacts of any individual project and to ensure land use 02160007.EIR. doc V.3-8 Land Use Northeast BakersfieM Bike Path and Water Facilities - Draft EIR compatibility. The projection of land use compatibility impacts as well as consistency with applicable development regulations would be speculative without environmental review of each project. V.3.4 MITIGATION MEASURES Implementation of the proposed project, including the issuance of a General Plan amendment and a conditional use permit for the proposed water treatment plant, would not result in any significant land use compatibility impacts or impacts on existing plans or policies. Therefore, no mitigation measures are required. V.3.5 LEVEL OF SIGNIFICANCE AFTER MITIGATION After issuance of a General Plan amendment and a conditional use permit for the proposed water treatment plant, the proposed project would not result in any significant land use compatibility impacts or impacts on existing plans or policies. I 02160007.EIR. doc V.3-9 Land Use Northeast BakersfieM Bike Path and Water Facilities - Draft EIR V.4 AIR QUALITY The analysis of air quality impacts is based on guidelines and information provided by the San Joaquin Valley Unified Air Pollution Control District (SJVUAPCD), the California Air Resources Board (CARB), the California Department of Transportation (Caltrans), the United States Environmental Protection Agency (EPA), and the National Oceanographic and Atmospheric Administration (NOAA). Furthermore, the environmental setting and regulatory framework are based on previous environmental documents prepared for the City of Bakersfield (MBA 1996). V.4.1 ENVIRONMENTAL'CONDITIONS Regional Settin~ The proposed project is located in and adjacent to the northeast portion of the City of Bakersfield in Kern County. This area is a part of the San Joaquin Valley Air Basin (Basin) of California, an area encompassing all of San Joaquin, Stamslaus, Merced, Madera, Fresno, Kings, and Tulare counties and the western and central portions of Kern County. The topography of the Basin consists of the relatively fiat valley floor surrounded by foothills and mountain ranges to the east, west, and south. The Basin is bounded on the west by the Coastal Ranges, on the north by the Sacramento Valley Air Basin, on the east by the Sierra Nevada mountains, and on the south by the Tehachapi Mountains (SJVUAPCD 1991). Climate The climate of the Basin, as with all of Central California, is dominated by the strength and location of a semi-permanent, subtropical high-pressure cell over the northeastem Pacific Ocean. The climate is also affected by the moderating effects of the nearby oceanic heat reservoir. Warm summers, cool winters, moderate rainfall, daytime onshore breezes, and moderate humidities characterize regional climatic conditions. In summer when the high pressure cell is strongest and farthest north, temperatures are very warm and humidities are low, but the daily incursion of the sea breeze into the Central Valley creates persistent breezes that help to moderate the summer heat. In winter, when the high pressure cell is weakest and farthest south, conditions are characterized by occasional rain storms interspersed with stagnant conditions and sometimes heavy fog. The average temperature is 65 degree Fahrenheit, with a high daily temperature in the summer averaging 95 degree Fahrenheit and mild winter temperature averaging 45 degree Fahrenheit. The airflow pattems in the Basin can generally be characterized by one of four directional types. However, seasonal variations do occur. During the summer, wind speed and direction usually originates at the north end of the San Joaquin Valley and flows in the south-southeasterly ~irection 02160007.EIR.doc V.4-1 Air Quality Northeast Bakersfield Bike Path and Water Facilities - Draft EIR through the valley, through Tehachapi Pass, into the Southeast Desert Air Basin (SEDAB) portion of Kern County. During the winter, wind speed and direction occasionally originates from the south end of the valley and flows in the north-northwesterly direction. Wind speeds during the winter months are light with variable winds of less than 10 mph. Low wind speeds combined with low inversion layers in the winter induce high CO concentration levels. Wind speed and direction change throughout the day, with the northwesterly winds prevailing. During the late evening and early morning hours, cooler drainage wind from the surrounding mountains generally slows and reverses direction. This interruption or transition of winds is known as an eddy. This phenomenon adds to the complexity of regional windrow and pollutant transport within the Basin. Terrain features make it possible for a varied microclimate to exist. The pattern of mountains and hills within the Basin is primarily responsible for the wide variations of rainfall, temperatures, and localized winds that occur throughout the region. Temperature variations have an important influence on Basin wind flow, dispersion along mountain ridges, vertical mixing, and photochemistry. Since the moderating marine influence decreases with distance, monthly and annual spreads between temperatures are greatest inland and smallest at the coast. Precipitation is highly variable seasonally. Summers are often completely dry, and there are frequent periods of four to five months with no rain. In the winter, an occasional storm from the high latitudes sweeps across the coast bringing rain. Annual rainfall is lowest in the inland valleys, higher in the coastal and inland foothills, and highest in the mountains. Central California frequently has temperature inversions that inhibit the dispersion of pollutants. Inversions may be either ground based or elevated. Ground based inversions, sometimes called radiation inversions, are most severe during clear, cold, early winter mornings. Under conditions of a ground~based inversion, very little mixing or turbulence occurs, and high concentrations of primary pollutants may occur locally to major roadways. Elevated or subsidence inversions can be generated by a variety of meteorological' phenomena. Elevated inversions act as a lid or upper boundary and restrict vertical mixing. Below the elevated inversion dispersion is not restricted. Mixing heights for elevated inversions are lower in the summer and more persistent. This low summer inversion puts a lid over the Basin and is responsible for the high levels of ozone observed during summer months in the Basin. Local Settin~ The project area experiences moderate temperatures and humidity. Temperatures average 65.5 degrees Fahrenheit (F) annually, ranging from average December low temperatures around 46.9 degrees F to average August high temperatures around 81.2 degrees F (Bakersfield Airport monitoring station). Rainfall in the project area averages 5.72 inches annually (Bakersfield Airport monitoring station) and occurs predominantly from November to March. (National Oceanographic and 02160007.EIR. doc V.4-2 Air Quality Northeast Bakersfield Bike Path and Water Facilities - Draft EIR Atmospheric Administration 1992). Winds in the study area average 8.2 mph and prevail predominately from the northwest (California Air Resources Board 1994). Air Quality Standards Ambient air quality is described in terms of compliance with state and national standards. Ambient air quality standards are the levels of air pollutant concentration considered safe to protect the public health (primary standards) and welfare (secondary standards). They are designed to protect people most sensitive to respiratory distress, such as asthmatics, the elderly, very young children, people already weakened by other disease or illness, and persons engaged in strenuous work or exercise. National Ambient Air Quality Standards (NAAQS) were established by the U.S. Environmental Protection Agency (EPA) in 1971 for six air pollution constituents. States have the oPtion of adding other pollutants, to require more stringent compliance, or to include different exposure periods. California Ambient Air Quality Standards (CAAQS) and NAAQS are listed in Table V.4-1. Attainment Status Designations The California Air Resources Board (CARB) is required to designate areas of the state as attainment, nonattainment, or unclassified for any state standard. An "Attainment" designation for an area signifies that pollutant concentrations did not violate the standard for that pollutant in that area. A "Nonattainment" designation indicates that a pollutant concentration violated the standard at least once, excluding those occasions when a violation was caused by an exceptional event, as defined in the criteria. An "Unclassified" designation signifies that data do not support either an attainment or nonattainment status. The California Clean Air Act (CCAA) divides districts into moderate, serious, and severe air pollution categories, with increasingly strict control requirements mandated for each. The EPA (EPA) designates areas for ozone (O3), carbon monoxide (CO), and nitrogen dioxide (NO2) as either "Does not meet the primary standards," or "Cannot be classified," or "Better than national standards." For sulfur dioxide (SO2), areas are designated as "Does not meet the primary standards," "Does not meet the secondary standards," "Cannot be classified," or "Better than national standards." In 1991, new "Nonattainment" designations were assigned to areas that had previously been classified as Group I, II, or III based on the likelihood that they would violate the national particul. ~-: matter (PM~0) standards. All other areas are designated "Unclassified" (CARB 1994). 02160007.EIR. doc V.4-3 A/r Quality Northeast BakersfieM Bike Path and Water Facilities - Draft EIR " TABLE V.4-1 i AMBIENT AIR QUALITY STANDARDS Ozone 0.09 ppm, 1-hr. avg. > i0.12 ppm, 1-hr. avg. 0.12 ppm, 1-hr. avg.

Source: California Air Resources Board 1991. Ozone. Ozone (03) is a colorless toxic gas that imtates the lungs and damages materials and I vegetation. Levels of 03 exceed national and state standards throughout the basin. Because 03 formation is the result of photochemical reactions between oxides of nitrogen (NOx) and reactive i organic gases (ROG), typically produced by combustion sources, peak concentrations of 03 occur 02160007.EIR. doc V.4-4 Air Quality Northeast BakersfieM Bike Path and Water Facilit~'es - Draft EIR downwind of precursor emission sources. The entire Basin, including Madera County, is designated as a nonattainment area for state (Severe) and federa! (Serious) 03 standards (CARB 1994). Carbon Monoxide. Carbon monoxide (CO) is a colorless gas, produced almost entirely from automobiles. This pollutant interferes with the transfer of oxygen to the brain. It is generally associated with areas of high traffic density. The Bakersfield area of the San Joaquin Valley has recently reached attainment status for this pollutant (SJVUAPCD 1998). Nitrogen Dioxide. Nitrogen dioxide (NO2), often used interchangeably with NOx, is a reddish-brown gas that can cause breathing difficulties at high levels. Peak readings of NO2 occur in areas that have a high concentration of combustion sources (e.g., motor vehicle engines, power plants, refineries, and other industrial operations) in the vicinity. The entire Basin, is designated as attainment for state NO2 standards and as unclassified/attainment for federal NO2 standards (CARB 1994). Total Suspended Particulates/Particulate Matter. On July 1, 1987, the EPA replaced the total suspended particulate (TSP) standard with a new particulate standard known as PM~o. PMlo includes only particulate matter 10 microns or less in diameter. Fine particulates pose a serious health hazard, alone or in combination with other pollutants. More than half of the smallest particles inhaled will be deposited in the lungs and can cause permanent lung damage. Fine particulates can also have a effect on health by interfering with the body's mechanism for cleating the respiratory tract damaging or by acting as a carder of an absorbed toxic substance. Sources of PMto include agricultural operations, industrial processes, combustion of fossil fuels, construction and demolition, and windblown dust and wildfires. The entire Basin is designated as nonattainment for state (Nonattainment) and federal (Serious) PM~0 standards (CARB 1994). Sulfur Dioxide and Lead. Significant exposure to sulfur dioxide can lead to reduced lung function, aggravation of respiratory diseases, irritation of eyes, and reduced visibility. Health effects associated with prolonged exposure to lead include gastrointestinal disturbances, anemia, kidney disease, and in severe cases neuromuscular and heurologic dysfunction. Sulfur dioxide (SO2), often used with sulfur oxides (SO~), and lead levels in all areas of the Basin do not exceed interchangeably national and state standards. The entire Basin is designated as attainment for state standards for these pollutants, and either unclassified or attainment under the federal SO2 standards. There is no NAAQS for lead. Air Quality Monitoring There are numerous air quality monitoring station locations throughout the Basin. The Chester Avenue CARB monitoring site best represents the air quality in the project area. This monitoring site was moved to a location on California Street in May of 1994. Ambient air quality data for the project 02160007.EIR. doe V.4-5 Air Quality Northeast Bakersfield Bike Path and Water Facilities - Draft EIR area were obtained from the SJVUAPCD's monitoring station, which offer monitoring data for the pollutants of concern at this site, ozone and PM10. Table V.4-2 summarizes the last five years of published data from this monitoring station.

The state 03 standard was exceeded from 22 to 66 days a year over the five-year period. The federal 03 standard was exceeded a total of 13 times during this period. The state PM~0 standard was exceeded in approximately 41 to 46 percent of the samples taken at the Bakersfield-Chester Street station over the five-year period. The federal standard was exceeded in approximately 2.3 to 3.0 percent of the samples, except for the 1993 and 1995 when exceedance of the federal occurred. years no PM10 Regulatory Framework Federal Clean Air Act The 1970 Clean Air Act (CAA) authorized the establishment of the NAAQS, and set deadlines for their attainment. The federal CAA Amendments of 1990 made major changes in deadlines for attaining NAAQS and in the actions required of areas of the nation that exceeded these standards. 02160007.EIR.doc V.4-6 Air Quality Nor&east Bakersfield Bike Pa& and Water Facilities - Draft E1R Pursuant to the CAA and subsequent amendments, the SJVUAPCD, the agency with jurisdiction over air quality in the Basin, prepared its 1993 Rate of Progress (ROP) Plan. The 1993 ROP Plan, which was submitted to the CARB for inclusion in the State Implementation Plan (SIP) for California, outlined how the SJVUAPCD proposes to reduce ozone forming pollution by providing a 15 percent reduction in emissions of volatile organic compounds (VOC) between 1990 and 1996. Other SJVUAPCD SIP submittals include the Post-1996 ROP Plan, which proposes to reduce emissions of VOC and/or oxides of nitrogen (NO×) by an additional 9 percent from 1990 levels, and the Ozone Attainment Demonstration Plan, which proves by computer modeling that NAAQS for ozone (03) would be reached by 1999 (SJVUAPCD 1996). Some of these Plans were revised and submitted and were all approved by the EPA in March 1996. The CAA requires that projects receiving federal funds prove conformity to the approved SIP/local air quality attainment plan for the region. Since California standards are more strict than federal standards, conformity with the California requirements should also satisfy the CCAA. California Clean Air Act The CCAA of 1988 requires that all air districts in the state endeavor to achieve and maintain CAAQS for 03, CO, SO2, and NO2 by the earliest practical date. Plans for attaining CAAQS were to be to the CARB by June 30, 1991. The CCAA specifies that districts focus particular attention submitted on reducing the emissions from transportation and area-wide emission sources, and the act gives districts new authority to regulate indirect sources. Each district plan is to achieve a 5 percent annual reduction, averaged over consecutive 3-year periods, in district-wide emissions of each nonattainment pollutant or its precursors. Any additional development within the region obviously would impede the "no net" increase prohibition, in that further emissions reductions must be affected from all other airshed sources to fit any project development mobile source emissions increase. A strict interpretation of the "no net" increase prohibition suggests that any general development within the region, no matter how large or small, would have a significant, project-specific air quality impact unless the development-related emissions are offset by concurrent emissions reduction elsewhere within the airshed. Any planning effort for air quality attainment would thus need to consider both state and federal planning requirements. San Joaquin Valley Air Basin Air Quality Attainment Plan The SJVUAPCD is the District with jurisdiction over air quality regulation in the Basin. To reach attainment of the state standards for 03, the SJVUAPCD has published its 1991 San Joaquin Valley Air Basin Air Quality_ Attainment Plan. Besides commitments to carry out all feasible control measures, the governing board in adopting the 1991 Plan on January 30, 1992 also committed to other o2~60oo~.E~,.ao~ V.4-7 Air Quality Nor&east Bakersfield Bike Pa& and Water Facilities - Draft EIR requirements of the CAA for severe nonattainment areas, including: implementation of a permit program (New Source Review, Rule 2201) designed to achieve no net increase in emissions of nonattainment pollutants, implementation of best available retrofit technology (BARCT) measures for existing stationary sources and implementation of transportation control measures, develop a strategy or transportation control measures (TCMs) to reduce vehicle trips, use and miles traveled, increase average vehicle ridership to 1.5 persons per vehicle during commute hours by January 1, 1999, reduce population exposure to nonattainment pollutants by 25 percent by December 31, 1994, and develop indirect and area source programs that include the Enhanced District CEQA Participation, the Air Quality Elements, and the New and Modified Indirect Source Review programs. The Plan could not demonstrate that emissions would be reduced by 5 percent a from 1987 levels in any target year year shown in the plan, therefore "every feasible measure" was included in the Air Quality Attainment Plan (AQAP) for maximum compliance. City of Bakersfield The City of Bakersfield has an Air Quality Element which contains several air quality policies. The following policies address air quality issues that are relevant to the proposed project: · Encourage land uses and land use practices which do not contribute significantly to air quality degradation. · Require dust abatement measures during significant grading and construction operations. Consider air pollution impacts when evaluating discretionary permits for land use proposals. Considerations should include: a) Alternative routes to reduce traffic access congestion. b) Development phasing to match road capacities. c) Buffers including increased vegetation to increase emission dispersion and reduce impacts of gaseous or particulate matter on sensitive uses. · Implement the Transportation System Management Program (July 1984) for Metropolitan Bakersfield to improve traffic flow, reduce vehicle trips, and increase street capacity. · Improve the capacity of the existing road system through improved signalization and traffic control systems. · Promote the use of bicycles by providing attractive bicycle paths and requiting provision of storage facilities in commercial and industrial projects. · Encourage walking for short distance trips through the creation of pedestrian friendly sidewalks and street crossings. · Promote a pattern of land uses which locates residential uses in close proximity to employment and commercial services in order to minimize vehicular travel. 02160007.EIR. doc V.4-8 Air Quality Northeast BakersfieM Bike Path and Water Facilities - Draft EIR V.4.2 PROJECT IMPACTS The operational characteristics of the proposed project involve the operation of a water treatment water pumps at the two lift (pump) stations, and a Class I bike path. These facilities will not plant, involve any substantial long-term emissions and will not result in any significant air quality effects. The following analysis thus focuses upon the anticipated emissions associated with project construction. Thresholds of Significance CEQA Significance Thresholds Appendix G (Significant Effects) of the Guidelines to the California Environmental Quality Act (CEQA) says that a project would normally be considered to have a significant effect on air quality if: · the project violates any ambient air quality standard, contributes substantially to an existing or projected air quality violation, or exposes sensitive receptors to substantial pollutant concentrations. The SJVUAPCD has also established criteria for determining the significance of construction emissions. Construction projects that emit the following precursor emissions of ozone above the following thresholds would normally be considered significant. · Reactive Organic Gases (ROG):10 tons/year · Oxides of Nitrogen (NOx): 10 tons/year The SJVUAPCD currently does not require quantification of PM~0 emissions. However, the SJVUAPCD does require strict compliance with the SJVUAPCD's Fugitive Dust Control Rules (Regulation VIII). When fully implemented, these measures will reduce impacts to levels considered less than significant. Construction Impacts Emissions produced during grading and construction activities are "short-term" in the sense that they occur during construction only. The proposed project is anticipated to occur in phases extending over approximately 2 to 3 years. Construction of the proposed project would produce emissions from construction equipment, transportation of workers, fugitive dust, and asPhalt paving. Exhaust emissions from construction include emissions associated with the transport of machinery and supplies to and from the site, emissions produced onsite as the equipment is used, and emissions from o2160o0~.glR.6oc V.4-9 Air Quality i Northeast Bakersfield Bike Path and Water Facilities - Draft EIR trucks transporting excavated materials from the site and fill soils to the site. Examples of these i emissions include CO, ROG, NOx, SOx, and PM10.

Numerous I variables factored into estimating total construction emissions include: level of activity, length of construction period, number of pieces and types of equipment in use, site characteristics, weather i conditions, number of construction personnel, and amount of materials to be transported on/off site. Additional exhaust emissions would be associated with the transport of workers and materials. The total estimated annual emissions from construction of the proposed project are presented in Table V.44. This includes the emissions anticipated from construction equipment, construction worker vehicles (based upon a worst-case average of 50 construction workers per day), grading activities and asphalt paving. Based upon the 10 ton annual threshold established by the SJVUAPCD, the level of NOx emissions would be a significant short-term impact of project implementation. The level of ROG emissions falls below the SJVUAPCD threshold of 10 tons per year and would not be considered a significant effect. Asphalt paving for the bike path and access road would produce ROG approximately 20.5 pounds (0.01 ton) of emissions during the evaporation of solvents contained in paving materials. However, all projects within the SJVUAPCD are required to comply with Rule 464, which would ensure that the impact will remain less than significant. 02160007.EIR. doc V.4-10 Air Quality Nor&east Bakersfield Bike Pa& and Water Facilit~'es - Draft EIR TABLE V.4-4 MAXIMUM ANNUAL CONSTRUCTION EMISSIONS ' (tons/year) Bike Path Construction Equipment }' 0.32 0.05 0.98 0.10 0.07 Construction Crew Trips ~ 0.59 0.04 0.04 ..... 0.01 Earthwork d .................... 23.21 Asphalt Paving ..... 0.01 ...............

Source: Michael Brandman Associates 1998. - Construction activities are a source of fugitive dust (PM10) emissions that can have a substantial, temporary impact on local air quality. Fugitive dust emissions are associated with land clearing, ground excavation, cut and fill operations, and truck travel on unpaved roadways. To a much lesser extent, PM10 emissions are also associated with the operation of construction equipment and construction workers vehicles. Dust emissions also vary substantially from day to day, depending on the level of activity, the specific operations, and weather conditions. Based upon the total area to be graded, the total estimated annual PMI0 emissions anticipated from the various phases of project construction is approximately 205 tons. 02 ~ 6oo07.Em. doo V. 4 - 11 A ir Quality Northeast BakersfteM Bike Path and Water Facilities - Draft E1R According to the SJVUAPCD, strict compliance with the SJVUAPCD's Fugitive Dust Control Rules (Regulation VIII) can result in impacts that are considered less than significant. Since all construction projects within the District are required to comply with Regulation VIII, the proposed project would not result in significant PM10 impacts. Consistency with Applicable Regional Plans The purpose of a consistency assessment is to determine if a project is inconsistent with the assumptions and objectives of the regional air quality plans, and thus if it would interfere with the region's ability to comply with federal and state air quality standards. The SJVUAPCD has prepared an Air Quality Attainment Plan (AQAP) for the San Joaquin Valley Air Basin in compliance with the requirements of the CCAA. The AQAP recognized growth of the population and economy within the Air Basin. The Plan predicted the workforce in Kern County to increase 40 percent and housing to increase 30 percent from 1990 to 2000 based on projections included in the General Plans prepared for individual Cities within the County. As discussed in Section VI of this DEIR, the proposed project would result in growth inducing impacts. However, these impacts would be consistent with the projected growth increase within the City of Bakersfield General Plan and the SJVUAPCD AQAP. Thus, the project's impact relative to consistency with regional air quality plans would be less than significant. V.4.3 CUMULATIVE IMPACTS Development of the proposed project and the related projects may result in cumulative short-term air quality emissions. The proposed project would result in significant short-term NOx emissions during construction activities. Therefore, if the related projects have a similar construction time frame, the project would significantly contribute to short-term NOx emissions. The proposed project would result in minimal long-term air quality emissions and would not significantly contribute to cumulative long-term air emissions. V.4.4 MITIGATION MEASURES The construction of the proposed project would result in the generation of fugitive dust. Compliance with SJVUAPCD Regulation VIII would result in no significant fugitive dust emissions. To ensure compliance, the following measure shall be implemented. AQ-1 Prior to the approval of plans and specifications or a grading plan for any component of the proposed project, the project applicant shall submit a letter to the City of Bakersfield Planning Department from the SJVUAPCD stating the dust suppression measures that will 02160007. EIR. doc V.4-12 Air Quality Northeast BakersfieM Bike Path and Water Facilities - Draft EIR be completed during construction activities to comply with SJVUAPCD Regulation VIII. These measures will include: · cover all access roads and parking areas with asphalt-concrete paving; use water sprays or chemical suppressants on all unpaved areas to control fugitive emissions; · enclose, cover, or water all stockpiled soils to reduce fugitive dust emissions; · c~hase grading activities during periods of high winds (greater than 20 mph over a one- hour period); · limit construction-related vehicle speeds to 15 mph on all unpaved areas at the construction site; · all haul trucks should be covered when transporting loads of soil; and · wash off construction and haul trucks to minimize the removal of mud and dirt from the project sites. The construction of the proposed project would include asphalt paving. Compliance with SJVUAPCD Rule 4641 would result in no significant ROG emissions. To ensure compliance, the following measure shall be implemented. AQ-2 Prior to approval of the plans and specification for the bike path, the City will obtain a letter from the SJVUAPCD stating the measures that will be completed during asphalt paving will comply with SJVUAPCD Rule 4641. The proposed project would potentially result in substantial air pollutant emissions, including NOx emissions from short-term construction activities on the project site. Following are the measures to reduce these potential impacts. AQ-3 The construction grading plans shall include a statement that all construction equipment will be tuned and maintained in accordance with the manufacture's specifications. AQ-4 The construction grading plans shall include a statement that work crews will shut off construction equipment when not in use. V.4.5 LEVEL OF SIGNIFICANCE AFTER MITIGATION Implementation of the above construction mitigation measures would reduce construction emissions. Even though construction equipment NOx emissions would be reduced by the above mitigation measures, the project would continue to result in significant and unavoidable emissions of NOx during project construction. ! 021,000,.~m.ao¢ V. 4-13 21ir Quality I ! i Northeast BakersfieM Bike Path and Water Facilities - Draft EIR V.5 NOISE I V.5.1 EXISTING CONDITIONS Acoustic Fundamentals Noise is oRen defined as unwanted sound. Sound is a mechanical form of radiant energy transmitted by pressure waves in the air, and is characterized by two parameters: amplitude (loudness) and frequency (tone). Amplitude Amplitude is the difference between ambient air pressure and the peak pressure of the sound wave, measured in decibels (dB) on a logarithmic scale. For example, a 10 dB sound is 10 times the pressure difference of a 0 dB sound; a 20 dB sound is 100 times the pressure difference of a 0 dB sound. Another feature of the decibel scale is the way in which sound amplitudes from multiple sources add together. A 65 dB source of sound, such as a truck, when joined by another 65 dB source results in a sound amplitude of 68 dB, not 130 dB (i.e., doubling the source strength increases the sound pressure by 3 dB). Amplitude is interpreted by the ear as corresponding to different degrees of loudness. Laboratory measurements correlate a 10 dB increase in amplitude with a perceived doubling of loudness and establish a 3 dB change in amplitude as the minimum audible difference perceptible to the average person (Federal Highway Administration 1982). Frequency Frequency, measured in Hertz (Hz), is the number of fluctuations of the pressure wave per second. The human ear is not equally sensitive to sound of different frequencies. Sound waves below 16 Hz or above 20,000 Hz cannot be heard at all, and the ear is more sensitive to sound in the higher portion of this range than in the lower. To approximate this sensitivity, environmental sound is usually measured in A-weighted decibels (dBA). On this scale, the normal of human hearing extends from about range 10 dBA to about 140 dBA. Exhibit ¥.5-1 lists several examples of the noise levels associated with common situations. Noise Descriptors The intensity of environmental noise fluctuates over time, and several descriptors of time-averaged noise levels are used. Three most commonly used are Leq, Ldn, and CNEL. The energy equivalent noise level, Leq, is a measure of the average energy content (intensity) of noise over any given period of time. Many communities use 24-hour descriptors of noise levels to regulate noise.

CNEL, the community equivalent noise level, is similar to Ldn, but adds a 5 dBA penalty to evening noise (7 p.m. to 10 p.m.). Characteristics of Sound Propagation and Attenuation Noise is generated by many sources, incl~uding mobile sources, such as automobiles, trucks, airplanes, and stationary sources, such as construction sites, machinery, and industrial operations. Noise generated by mobile sources typically attenuates at a rate of 3.0 dBA per doubling of distance. The rate depends on the ground surface and the number or type of objects between the noise source and the receiver. Noise generated by stationary sources typically attenuate at a rate of 6.0 dBA per doubling of distance. Sound levels can be reduced by placing barriers between the noise source and the receiver. In general, barriers contribute to decreasing noise levels only when the structure breaks the "line of sight" between the source and the receiver. Buildings, concrete walls, and berms can all act as effective noise barriers. Wooden fences or broad areas of dense foliage can also reduce noise, but are less effective than solid barriers. Human Response to Noise The human response to environmental noise is subjective and varies considerably from individual to individual. The health effects of noise in the community arise from interference with human activities, including sleep, speech, recreation, and tasks demanding concentration or coordination. Hearing loss can occur at the highest noise intensity levels. The acceptability of noise and the threat to public well- being are the basis for land use planning policies preventing exposure to excessive community noise levels. I People can detect changes of as little as 1 dB in a laboratory environment. However, as a practical matter, changes of 1-2 dB are usually required before a person can detect a change in sound level i outside the laboratory with any certainty. Typically, a change of 3 dB is noticeable, a change of 5 dB is clearly noticeable, and a change of 10 dB is perceived as a doubling (or halving) of the sound level. I Existing Noise Sources i The project area consists predominantly of open space. Noise levels from Alfred-Harrell Highway produce some traffic-related noise levels and traverse the northern portion of the project area. Recreational activity at the. Kern County Soccer Park is also a source of noise west of the I 02160007.EIR. doc V.5-2 Noise I Northeast Bakersfield Bike Path and Water Facilities - Draft EIR northwesterly portion of the project site. Moving water within the Kern River is also an existing noise source adding to the ambient noise levels of the northern portion of the project area. Sensitive Receptors The vast majority of the project area is primarily open space; however, there are sensitive noise receptors within the project vicinity. These sensitive noise receptors include rural residences, the animals at CALM, and the Kern County Soccer Park. Regulatory Settin~ I State of California 1 To limit population exposure to physically and/or psychologically damaging noise levels, the State of California, various county governments, and most municipalities in the state have established standards and ordinances to control noise. The California Department of Health Services (DHS) Office of Noise Control has' studied the correlation of noise levels and their effects on different land · uses. As a result, the DHS has established four categories as guidelines for judging the severity of noise intrusion on specified land uses. These guidelines have been established for long-term noise. _ The state has not established noise guidelines for short-term construction noise levels. I Local I The project area lies within the City of Bakersfield and the County of Kern. The proposed project would be subject to the respective noise ordinances covering construction noise for each jurisdiction. 1 Specifically, noise within the City of Bakersfield is restricted to the hours of 6:00 a.m. to 9:00 p.m. Monday through Friday and 8:00 a.m. to 9:00 p.m. Saturday and Sunday. Construction within the · County of Kern is limited to 6:00 a.m. to 10:00 p.m. Monday through Sunday. V.5.2 PROJECT IMPACTS I The operational characteristics of the proposed project involve the operation of water pumps at the two pump stations, facilities at the water treatment plant, and use of a Class I bike path. No significant long-term noise impacts (i.e., increases of more than 3 dBA above' the existing ambient noise level) will result from these components of the proposed project. Short-term noise impacts related to 1 construction activity will occur, however, and will vary dependent upon the phasing of construction activities that are anticipated to occur over the two to three year period. · I 02160007. EIR. doc V. 5 -3 JVoi/s e I Nor&east BakersfieM Bike Pa& and Water Facilities - Draft EIR Thresholds of Significance As noted previously, the substantial noise associated with implementation of the project would be from short-term construction impacts. Any violation of the City of Bakersfield or County of Kern noise standards relating to construction would be considered a significant impact. Specifically, the City Municipal Code Chapter 9.22 limits construction activities to the hours of 6:00 a.m. to 9:00 p.m. Monday through Friday and 8:00 a.m. to 9:00 p.m. on Saturday and Sunday. The County of Kern limits construction activities to the hours of 6:00 a.m. to 10:00 p.m. Monday through Sunday. No federal or state noise standards are applicable to this project. Construction Noise Construction noise impacts axe considered short-term impacts in the sense that they occur only during periods of project construction. Earthmoving, materials handling, stationary, equipment, and vehicles generate noise during clearing, excavation, grading, and building operations associated with the development of the proposed project. These activities would alter the characteristics of the noise environment as the project is constructed. Actual noise levels generated by equipment and experienced at nearby and adjacent residences during construction would vary hourly, daily, and weekly because the number and types of equipment used would vary. Noise sources include various construction equipment such as graders, dozers, trucks, loaders, backhoes, and excavators. Table V.5-1 lists the range of sound level from construction equipment and the recommended levels for noise impact assessment. Typical operating cycles may involve 1 or 2 minutes of full power operation followed by 3 to 4 minutes at lower power settings. Depending on the project component, there will be a range of pieces of equipment that will be used during grading operations. Grading of the water treatment plant site will require substantially more pieces of equipment than grading the bike path. Based on information from the project engineers, each project component will require the following pieces of equipment: bike path (3 pieces), ponds (7 pieces), intake structure (3 pieces), pipeline (3 pieces), and water treatment plant (22 pieces). It is assumed that the following pieces of equipment would be working in unison and their noise could oe additive. Noise levels from 3 pieces of equipment working in unison along the bike path, intake structure, and pipeline would generate a noise level of 92 dBA at 50 feet. The construction equipment required for the access road would generate similar noise levels. Noise levels from 7 pieces of equipment working in unison at the ponds would generate a noise level of 95 dBA at 50 feet. Noise levels from 22 pieces of equipment working in unison on the water treatment plant site would generate a noise level of 98 dBA at 50 feet. 02160007.EIR. doc V.5-4 Noise Northeast BakersfteM Bike Path and Water Facilities - Draft EIR TABLE V.5-1 NOISE LEVELS GENERATED BY TYPICAL CONSTRUCTION EQUIPMENT Pile Drivers, 81-96 93 12,000-18,000 it-lb/blow Rock Drills 83-99 96 Jack Hammers 75-85 82 Pneumatic Tools 78-88 85 Pumps 68-80 77 Dozers 85-90 88 Tractor 77-82 80 Front-End Loaders 86-90 88 Hydraulic Backhoe 81-90 86 Hydraulic Excavators 81-90 86 Graders 79-89 86 Air Compressors 76-86 86 Trucks 81-87 86 Source: Noise Controls for Buildings and Manufacturing Plants, BBN 1987. Noise from the construction equipment will attenuate over distance because of spreading losses and absorption of the intervening terrain. Spreading losses account for an attenuation factor of 6 dBA per doubling of the distance. As an example, for "line-of-sight" noise in the absence of any intervening terrain, a 98 dBA level projected at 50 feet would be reduced to 92 dBA at 100 feet, 86 dBA at 200 feet, 80 dBA at 400 feet, etc. Soft surfaces with intervening vegetation also attenuate noise through absorption as it passes over the terrain. Attenuation associated with absorption is highly dependant on the terrain and vegetation characteristics and can only be predicted based on actual field measurement. The rate of attenuation from absorption is typically low and as a reasonable worst-case scenario, is not included in this study. During the construction of the project, noise from construction activities would potentially impact noise-sensitive land uses in the immediate area. Noise sensitive residences that were analyzed range in distance of 50 feet from the project site to approximately 2,000 feet. In addition, CALM and the Kern County Soccer Park are considered noise sensitive uses and are in close enough proximity to portions of the project site to be affected by construction activities. The noise sensitive land uses that were analyzed are included in Table V.5-2 and illustrated on Exhibit V.5-1. Table V.5-2 illustrates the maximum anticipated exterior noise levels at each of the noise sensitive land uses. Each of the land uses is matched with the noise source that is anticipated to generate the maximum exterior noise level at the land use. The distance of each noise sensitive land use from the noise source is also provided in Table V. 5-2. 02 160007.EIR. doc V. 5 =5 Noise I '~'~, ,~' ~' ~,?" , o L, , -PA~oI~O ORiVE PANO~MA DRIVE I LEGEND: ~ Residence I ~ Residence7 ! ~ Residence2 ~'~ CALM ~ Residence 3 ~ Kern County Soccer Park I ~-~ Residence 4 [--i'~ Church ~ Residence 5 ~ School I ~1 Residence 6 ~ Camp Okihi Group Site II[][]fl Sensitive Noise Receptors Michael Brandman ^ssociates 02160007- 7/98 NORTHEAST BAKERSFIELD BIKE PATH AND WATER FACILITIES I Northeast BakersfteM Bike Path and Water Facilities - Draft EIR TABLE V.5-2 MAXIMUM ANTICIPATED EXTERIOR NOISE LEVEL AT NOISE SENSITIVE LAND USES Bike Path Residence I 50 92 dBA Water Facilities: Intake Structure/Pond CALM 200 83 dBA Residence 2 400 77 dBA Pipeline Kern County Soccer Park 100 86 dBA Camp Okihi Group Site 400 74 dBA Residence 3 500 71 dBA Residence 4 1000 65 dBA Water Treatment Plant Residence 5 400 80 dBA Residence 6 1000 73 dBA Residence 7 1400 69 dBA Access Road Church 200 80 dBA School 400 74 dBA a Please refer to Exhibit V. 5-1 for location of noise sensitive land uses. Source: Michael Brandman Associates. As shown above, project grading activities would a of noise levels between 65 dBA generate range and 92 dBA at the noise sensitive land uses that were analyzed. The duration of these maximum noise levels would vary depending on the project component. The duration of grading activities at one location along the bike path would be substantially shorter than the duration of grading activities at the water treatment plant. The approximate construction timing for each of the project components that would generate maximum exterior noise levels at the sensitive land uses depicted in Table V.5-2 is: bike path (200 linear feet per day), ponds with high litt station and turnout structure (10 weeks), intake structure with low litt pump station (10 weeks), pipeline (150 to 200 linear feet per day), access road (approximately 200 linear feet per day), and water treatment plant (20 to 24 weeks). These durations are for grading activities and construction activities associated with buildings and structures would result in additional noise levels; however, noise levels the maximum grading are expected to generate noise levels at the adjacent noise sensitive land uses. Construction activities would be temporary in nature and would occur during the daytime hours. Construction noise impacts could result in annoyance or sleep disruption for nearby residents if nighttime operations were to occur or if equipment is not properly muffled or maintained. Similarly, construction noise could potentially interfere with nearby recreational activities disturbance at CALM. construction or create However, noise will be short-term and is exempt per the City of Bakersfield Municipal Code if restricted to 6:00 a.m. to 9:00 p.m. Monday through Friday, and 8:00 a.m. to 9:00 p.m. on Saturday and Sunday. The County of Kern maintains similar restrictions on construction activity, limiting hours to 6:00 a.m. to 02160007.EIR. doc V.5-6 Noise Northeast BakersfieM Bike Path and Water Facilitt'es - Draft EIR 10:00 p.m. Monday through Sunday. No significant short-term noise impacts would result from construction activities. V.5.3 CUMULATIVE IMPACTS The development of the proposed project and related projects would increase noise levels within the project vicinity. However, given the location of the related projects, the proposed project would not contribute cumulative short-term noise levels and would minimally contribute to long-term noise levels. Therefore, the proposed project would not significantly contribute to cumulative noise levels in the project vicinity. V.5.4 MITIGATION MEASURES No measures are required. V.5.5 LEVEL OF SIGNIFICANCE AFTER MITIGATION Implementation of the proposed project would not result in any significant impact.

The complete reports are contained in I Appendix D. I V.6.1 EXISTING CONDITIONS I Archaeological/Historical i Data Sources A records search was conducted at the Southern San Joaquin Valley Information Center. The records I search indicated that the northern end of the bike path, the intake structure, the 36 inch water line route, and the ponds had been included in a previous survey conducted for the existing soccer fields I located between Alfred Harrell Highway and the Kern River. Except for the 40-acre water treatment plant site, most of the project site between Alfred Harrell Highway and Paladino Drive had previously been surveyed for the revised Morning Drive alignment project by the City of Bakersfield. Most of Ithe project site along the Paladino Drive alignment had been surveyed during the Mojave Pipeline Evaluation and for a sewer line. The 40-acre water treatment plant site had not been surveyed. I Natural Setting I The floor of the valley is 750 km long and 30-80 km wide and is enclosed by the Siskiyou, Sierra Nevada, Tehachapi, and Coast Mountain ranges. It is underlain mainly by Sierran stream sediments i up to 17 km deep. Elevation ranges from sea level to 100 m AMSL, broken only by the 600 m high Sutter Buttes. The Sacramento and San Joaquin River systems drain the valley and merge into the channels and marshes of the Sacramento-San Joaquin Delta. The waters later pass through a gap in I the Coast Range and empty into San Pablo Bay. i Over the centuries the valley experienced many dramatic environmental changes, including:, faunal extinctions and replacement at the end of the Pleistocene, the emergence of wetlands, flooding, massive siltation, cyclical appearance and evaporation of shallow lakes, and biogeographic shifts in I response to climatic fluctuations. i In ancient times, lakes, marshes, and sloughs covered more than 5,000 square km in the San Joaquin Valley alone. The largest lake, Tulare, occupied a structural basin created by downwarping. Also, Tulare and Buena Vista Lakes were partially contained by alluvial fans reaching into the valley from I 02~60007.~IR. doc ¥.6-1 Cultural Resources I Northeast BakersfieM Bike Path and Water Facilities - Draft E1R the King's River and Los Gatos Creek. These coalesced into a ridge and lands to the south were so arid that runoff was often not able to maintain a discharge through the alluvium. This natural dam thus contributed to the impoundment of Tulare Lake and its swampy basin. A similar projection from the Kern River fan westward to the McKittrick Hills formed a second dam behind which lie Kern and Vista Lakes. At flood levels the Buena Vista and Tulare Lakes spilled into a single basin, and Buena with the waters of the Kern, Kaweah, and King's Rivers, flowed into the San Joaquin River system. The lakes are now mostly dry due to historic drainage projects. The Central Valley was attractive to the early inhabitants. The climate was locally varied, but also variable and in the southern San loaquin Valley, where it generally pleasant. Precipitation was was scant, the water was supplemented by the snowmelt from the mountains. The Central Valley's plains and wetlands had abundant game and vegetal foods. The bottomlands produced lush swamp vegetation valued for food, fiber, and building materials. Riparian woodlands grew along the watercourses. The waterways also provided the habitats for river mussels and many species of fish.. Steatite and asphaltum occurred in the southern part of the valley and salt deposits were found in the north. With so many abundances, resources that were lacking, such as obsidian, were easily obtainable through trade with outside areas. With such an abundance of resources and comfortable living conditions, the eighteenth century aboriginal population was 105,000, with 53,000 people in the Sacramento Valley and 52,000 in the San Joaquin. During the long prehistory of the Central Valley, there have been diverse and changing environments, along with many population movements, waves of cultural influences from neighboring groups, and a complex interplay between local and regional cultural forces. The oldest evidence for occupation of the valley comes from Tracy, Tulare, and Buena Vista Lakes and dates to about 11,500-7,500 years Since the floor of the valley is covered with a thick layer of alluvium, it is likely that most of the ago. earliest habitation evidence lies buried beneath it. This would account for the modest antiquity of artifacts, especially in the valley lowlands of the San Joaquin and Sacramento River drainages. In these areas 10 meters of sediments have accumulated just during the past 5,000-6,000 years. Area History The project area lies within the territory of the Southern Valley Yokuts. The territory of the Southern Valley Yokuts included Tulare, Buena Vista, and Kern Lakes, their connecting sloughs, and the lower portion of the Kings, Kaweah, Tule, and Kern Rivers. The area consisted of extensive swamps and marshlands which provided an enormous variety and abundance of wildlife and aquatic flora. The southern San Joaquin Valley received only 5-10 inches of rain annually and was dependent upon the additional water being brought in from the melting snows of the Sierra Nevadas. As the Yokuts adapted to this abundance of subsistence resources they developed a culture of comparatively greater material wealth and tended to live in large, more permanent settlements. It is estimated t!. '.~ this way 0216000'/.EIR.doc V. 6-2 Cultural Resources i Northeast Bakersfield Bike Path and Water Facilities - Draft EIR of life lasted approximately 2,000 years. At the beginning of the historic period 15 different Yokuts I groups were identified in the area. Adapting to their environment, the southern Valley Yokuts developed a mixed economy subsistence I It emphasized fishing, hunting waterfowl, and collecting shellfish, roots, and seeds. Most of pattern. their region was treeless except for the cottonwoods, sycamores, and willows that lined the river I channels and sloughs. Oaks did not extend very far onto the valley floor and, therefore, acorns were not readily available. They were generally obtained by trade with neighboring groups. I Small land mammals and birds were only a small portion of the native diet and the Southern Valley Yokuts rarely ventured into the open country to capture antelope and elk. They did, however, capture i many of the larger mammals when they came to the lakes and sloughs for water. Various cooking methods were employed. Tule roots and seeds were ground into meal, mixed with I water, and stone-boiled in baskets. Fish and meat were broiled and roasted on coals and ashes. Small earth ovens were used to bake both vegetable and animal foods. Salt grass was used for seasoning. i Firewood was at a premium and dried tules were usually substituted. Single family residences were constructed by using long poles, limbs, or sticks with one end set on the I ground in an oval pattern, and the other ends brought together at the top to form a fi.me that was then covered with mats made from tule reeds. Some groups, using the same materials, built a distinctive i long, steep-roofed communal house. The Yokuts technology was also shaped by the source of raw materials available. The very important I tule provided the basis for their highest technological skill - basket weaving. The baskets varied in shape and use and included bowl-shaped cooking containers, conical burden baskets, flat winnowing i trays, seed beaters, and a unique necked water bottle. No significant number of Southern Valley Yokuts came under the control of the coastal Franciscan I missionaries; however, significant impact to their culture resulted from infiltration of escaped natives from the missions. The runaways introduced foreign practices from their cultures that had suffered i greatly from non-practice and practices acquired from the missions. Complete cultural breakdown and near-total disappearance of native peoples fi.om the San Joaquin Valley came with the annexation of California by the United States. The land passed quickly into the hands of the settlers. The process I was relatively since the native peoples offered little effective resistance. easy I Because of the early and rapid decimation of the Southern Valley Yokuts and the rapid collapse of their culture, there is relatively little published literature regarding them, and ethnographic descriptions obtained from aged informa' :s is certainly incomplete. I 02160007.EIR.doc V.6-3 Cultural Resources I I Northeast BakersfieM Bike Path and Water Facilities - Draft EIR I Archaeological/Historical Resources I Based on a records search, no archaeological sites are recorded on the project, however, there is one recorded prehistoric site within 600 feet of the proposed bike path and pipeline alignment between I Alfred Harrell Highway and Paladino Drive. This previously recorded site, CA-KER-2579, is located on a hill well above and outside the alignment. 1 1 During the field survey, a mine shaft with associated cement footings was located along the bike path and pipeline alignment on the east side of the canyon and approximately 1,500 feet south of Alfred 1 Harrell Highway. Directly across the canyon to the west is a large cement foundation. Pictures of these historic features were shown to both a long time Bakersfield resident and a geologist. Neither · person could identify the features. At this point it is unclear how old the features are and exactly what their function was. Paleontoloeical Resources I Data Sources I The paleontologic assessment included an archival records check at the Los Angeles County Museum of Natural History, which included the collections data of the (1) University of California, -Los Angeles, (2) Calif°mia Institute of Technology, and (3) 'University of California Museum of Paleontology (Berkeley). Pertinent geologic and paleontologic literature was ~earched and reviewed. Geology and Paleontology Sedimentary rock units exposed in the project area are the Round Mountain Silt Member of the (marine; Upper Miocene), Chanac Formation (nonmarine, upper Miocene), "Santa Temblor Formation Margarita" Formation (marine, upper Miocene), Kern River Formation (nonmarine; upper Miocene, Pliocene, and early Pleistocene), and Quaternary terrace deposits (nonmarine; upper Pleistocene- Holocenc). Following is a discussion of each rock unit and only the Round Mountain Silt appears to have significant paleontologic resources in this particular area. Quaternary AlluviurnFFerraces (upper Pleistocene-Holocene) These stream deposits comprise most of the designated map area, particularly in the southern part. Fossil occurrences in Quaternary alluvium are very spotty; elsewhere stream deposits have yielded significant finds of mammoth, mastodon, bison, bear, lion, camel, horse, reptiles, birds, ground sloths, insects, and plants. Such discoveries are highly significant, but their infrequent occurrence and suggests this unit has low paleontologic sensitivity. 0216o007.Em. aoc V. 6-4 Cultural Resources Nor&east BakersfieM Bike Pa& and Water Facilit~'es - Draft EIR Kern River Formation (upper Miocene, Pliocene, and early Pleistocene) This unit consists of fluvio-lacustrine gravels, sands, and clays, and is described in detail by Bartow and Pittman It is at elevations in the northern half of the project area. Although (1983). exposed high there is potential to recover a diversity of significant terrestrial and freshwater fossils, the paleontologic sensitivity of these sediments is generally low. Chanac and "Santa Margarita" Formations (upper Miocene) The nonmarine Chanac Formation, which is distinguished by its buff to brown color, overlies the marine white sandstone of the "Santa Margarita" Formation. In the Tejon Hills, the Chanac has yielded terrestrial vertebrates (Merriam, 1916) and the "Santa Margarita" bears late Miocene mollusks (Addicott, 1970). In the Kern River area, however, these formations appear to be nonfossiliferous. Thus, their paleontologic sensitivities at the project site are probably low. Round Mountain Silt Member, Temblor Formation (middle Miocene) The Round Mountain Silt is the youngest member of the Temblor Formation. Microfossil and strontium isotope data indicate that the Round Mountain Silt from approximately 15.9 to 14 Ma ranges in this area (Olson, 1990). It is of particular paleontologic importance because its upper part includes the famous Sharktooth Hill bonebed. The bonebed ranges from four inches to nearly three feet in thickness, and is generally about a foot thick. One cubic foot of sediment may contain over 100 individual bones and teeth! k's vertebrate fauna of more than 100 species includes boney fish, cartilagenous fish (especially shark teeth), turtles, crocodiles, birds, sea lions, whales, and desmostylians (an extinct hippo-like aquatic mammal), and terrestrial mammals such as tapir, horses, camel, "giraffe", mastodon, and rhinoceros. Sharktooth Hill is at elevation 643 feet and is approximately 1.4 miles northwest of the project area. It is known as "probably the most significant 'Miocene marine vertebrate locality in the world", and it is listed in the United States Landmark Registry. The bonebed extends over ten square miles from north of Poso Creek to south of the Kern River. In the vicinity of the rroject site, the unit is well-exposed in the bluffs facing the Kern County Soccer Park, where it has been extensively quarried for fossils. In addition to vertebrates, important invertebrate fossils have been recovered from the Round Mountain Silt in this region. The "Barker's Ranch fauna", the largest Miocene molluscan fauna of the Pacific Coast, extends from near the base of the Olcese Sand Member to the top of the Round Mountain Silt, and is the standard for the Temblor macrofossil stage. All considered, the paleontologic sensitivity of the Round Mountain Silt in this area is extremely high. I 02160007.EIR. doc V. 6-5 Cultural Resources ! Northeast Bakersfield Bike Path and Water Facili~es - Draft EIR Paleontological Resources Based on a records search, several vertebrate fossil localities are in this unit within the project area, and numerous other localities are in correlative strata in the hills north of the Kern River. Those in the vicinity of the project area on the south side of the river are located east and west of the proposed bike path and pipelines and south of Alfred Harrell Highway. The most prominent fossil locality in the project area is one of three major quarries in the Sharktooth Hill bonebed made in late 1981 by LACM and Kem County Museum. This bonebed, which is usually less than a foot thick, is within the upper part of the Round Mountain Silt at elevations between 600 and 700 feet. Many thousands of vertebrate fossils were recovered from the almost 40 square meters of bonebed excavated at that LACM locality. Two fossil baleen whales were discovered just above the bonebed at another LACM locality within the project area. The Sharktooth Hill bonebed extends more than 10 square miles and has yielded a vertebrate fauna of more than 100 species includes boney fish, cartilagenous fish (especially shark teeth), turtles, crocodiles, birds, sea lions, whales, and desmostylians (an extinct hippo-like aquatic mammal), and terrestrial mammals such as tapir, horses, camel, "giraffe", mastodon, and rhinoceros. It is probably the most significant Miocene marine vertebrate locality in the world. In addition to the bonebed vertebrates, important invertebrate fossils have been recovered from the Round Mountain Silt in this region. The "Barker's Ranch fauna", the largest Miocene molluscan fauna of the Pacific Coast, extends from near the base of the Olcese Sand Member to the top of the Round Mountain Silt, and is the standard for the Temblor macrofossil stage. All considered, the paleontologic sensitivity of the Round Mountain Silt in this area is extremely high. V.6.2 PROJECT IMPACTS Thresholds of Significance Appendix G of the CEQA Guidelines indicates that a project would normally be considered to have a significant effect on cultural resources if the project would disrupt or adversely affect a prehistoric or historical archaeological site or a property of historic or cultural significance to a community or ethnic or social group. Impacts on paleontological resources are considered significant if a project may cause damage to an important paleontological resource. I I 02160007.EIR.doc V. 6-6 Cultural Resources ! ! I Northeast BakersfteM Bike Path and Water Facilities - Draft EIR Archaeological/Historical Resources I' The archaeological survey and reconnaissance revealed a potential impact to the mine shaf~ located along the proposed bike path and water pipeline alignment approximately 1,500 feet south of Alfred I Harrell Highway. This potential impact is considered significant. No other historic sites or features were located. No prehistoric sites were found. The previously i . recorded site, CA-KER-2579, will not be affected with the implementation of the proposed project. I Paleontological Resources Ii Even though the Sharktooth Hill bonebed is usually less than a foot thick, potential faults in the project area could have varied the elevation of the bonebed. Based on the records search and field observations, the portions of the proposed bike path, raw water pipeline, potable water pipeline and taccess road sites that are located between elevation 600 feet and 700 feet may result in significant impacts on paleontological resources. V.6.3 CUMULATIVE IMPACTS The proposed project and related projects are located in an area known to contain cultural resources. Therefore, implementation of the project and other past, present, and reasonably anticipated future iprojects could potentially result in significant cumulative impacts to cultural resources. However, with implementation of the mitigation measures provided below, the potential cumulative impacts to cultural resources could be reduced to a level considered less than significant. I V.6.4 MITIGATION MEASURES I Archaeological/Historical Resources I CR-1. Prior to the approval of plans and specifications and grading permits, a qualified archaeologist shall conduct testing of the mine shaft to determine the significance of historical resources along the proposed bike path and pipeline. If the mine shaft is i determined to be significant, a report shall be submitted to the State Historic Preservation ' Office (SHPO) for review and comment. If, based on the findings of the report and recommendations by SHPO, the mine shaR is eligible for listing in the National Register of f'lil Historic Places, a Memorandum of Agreement (MOA) pertaining to this site will be developed to ensure the project's compliance with Section 106 of the National Historic Preservation Act (36 CFR 800). All Section 106 actions will be coordinated with SHPO and the Advisory Council on Historic Preservation. Potential mitigation may involve data recovery for the mine shaft. I 02160007.EIR. doc V.6-7 Cultural Resources I Nor&east BakerafieM Bike Pa& and Water Facilit~'es - Draft EIR Paleontological Resources A paleontological monitoring program that includes the following measures shall be implemented to reduce potential impacts on the Sharktooth Hill bonebed. CR-2. Prior to grading, a paleontologist shall be retained, attend a pre-grading meeting, and set forth the procedures to be followed during the monitoring program. CR-3. One paleontological monitor that is trained and equiped to allow rapid removal of fossils with minimal construction delay is expected 'to be sufficient. Full-time monitoring of the portions of the project site that have earth-disturbing activities at elevations between 600 feet and 700 feet shall be provided. CR-4. If fossils be found within an area being cleared or graded, earth-disturbing activities shall be diverted elsewhere until the monitor has completed salvage the fossils. If construction personnel make the discovery, the grading contractor shall immediately divert construction and call the monitor to the site. Major salvage time may be shortened by grading contractor's assistance (e.g., removal of overburden, lifting and removing large and heavy fossils). CR-5. The project paleontologist shall prepare, identify, and curate all recovered fossils. Upon completion of grading, the project paleontologist shall prepare a summary report documenting mitigation and results, with itemized inventory of collected specimens. The paleontologist shall submit the report to the City of Bakersfield, designated depository, and any other appropriate agency, and transfer fossil collection to an appropriate depository. The summary report shall be submitted to the City. This submittal will signify completion of the program to mitigate impacts on paleontologic resources. V.6.5 LEVEL OF SIGNIFICANCE AFTER MITIGATION After implementation of the above mitigation measures, impacts to cultural (archaeological, historical, and paleontological) resources would not be significant. ! 02160007.EIR. doc V.6-g Cultural Resources !

The project is located on undeveloped parkland, directly adjacent to Hart Memorial Park, the Kern County Soccer Park, and CALM. The portion of the project site that is located between Alfred Harrell Highway and Paladino Drive contains a ravine and consists primarily of rolling hills. Ant Hill, which has an elevation of 960 feet, is located directly east of the small canyon. A small plateau is also located within this portion of the project site. The majority of this area of the project, as well as adjacent areas, also includes undeveloped open space with grassland vegetation. Residential structures and other livestock associated structures are located immediately east of the project area.

V.7.2 PROJECT IMPACTS Thresholds of Significance The significance determination of a change in the visual and aesthetic character of a site and the surrounding area is largely subjective. For the purpose of this analysis, an impact on the visual and aesthetic nature of the area is considered to be significant if the project would obstruct an existing public scenic vista, or if thc .~roject would substantially alter the existing visual character of the area or 02160007.EIR.doc V. 7-3 Aesthetics Northeast BakersfieM Bike Path and Water Facilities - Draft EIR any designated scenic element. An additional common threshold for aesthetic impacts is an obstruction of a vies from a designated scenic highway, however, there are no designated scenic highways in the project vicinity. Short-term Impacts Implementation of the proposed project would include construction of the proposed bike path and water facilities on'. approximately 70 acres. Approximately 92 acres would be disturbed during grading activities. Except for the Hart Memorial Park conveyance pipeline, construction activities for all of the project components are anticipated to be phased over an approximately 2 to 3-year period. The Hart Memorial park conveyance pipeline is anticipated to be constructed subsequent to the completion of the project eom >onents. Bike Path Construction activities associated with the proposed bike path are not expected to result in a significant alteration of existing views. As construction activities occur south of Alfred Harrell Highway into the existing ravine, motorists along Alfred Harrell Highway could view the construction activities. Due to the expansive open space view south of Alfred Harrell Highway, construction activities would alter a small portion of a motorist's open view. This alteration in the motorist's view would not be significant. Partial views of the ravine can be obtained from the Kern County Soccer Park and CALM; however, due to the distance (approximately 0.5 mile), no significant alteration of views from these two uses would occur during construction activities associated with the bike path. There are existing: residences that are located north of Paladino Drive and east of the proposed bike path. These residences could view the construction activities along the bike path and into the ravine. Due to distance and minimal pieces of construction equipment needed to construct the bike path, no significant alteration of views would occur at the residences that are located east of the bike path. As construction activities associated with the bike path extends to the west toward Fairfax Road, existing residences near Fairfax Avenue and south of the proposed bike path would not have views. As construction activities extend directly adjacent to the existing residences, these activities will be located on terrain that is approximately 50 feet higher in elevation compared to' the elevation of the residences. Views of construction activities adjacent to the residences would be partially obstructed by the existing terrain. As construction equipment is used to grade the bike path to connect the bike path to Fairfax Avenue, existing residences near Fairfax Road will have views of the construction 0216000/.EIR. aoc ¥.7-4 Aesthetics ! .... Northeast Bakersfield Bike Path and Water Facilities - Draft EIR ,! activities. The construction activities associated with the construction of the bike path are not i l expected to significantly alter the existing views of the surrounding uses. Water Facilities 'l~ Construction activities associated with the proposed water facilities will visually alter the aesthetic i character of the portion of the site north of Alfred Harrell Highway. Construction activities will 1 ~ include excavation and grading for the intake structure, low lift station, pond, high lift station, and the Hart Memorial Park conveyance pipeline. Substantial grading activities would occur to create the i . proposed pond and intake structure. Visitors of the Kern County Soccer Park and motorists along Alfred Harrell Highway will have the most extensive view of construction activities at the pond. Even i though these visitors and motorists would have an extensive view of the construction activities, no · significant impact on these visitors' and motorists' views would occur because the intensive activities associated with the grading would occur during a short time frame (i.e., 10 weeks for the pond and 10 l weeks for the intake structure). Views of the construction activities north of Alfred Harrell Highway · from CALM would primarily be along the northern perimeter of the existing CALM facility. These I views would include intensive construction activities associated with grading; however, since the . grading activities would occur during a relatively short time frame, no significant alteration of the existing views from CALM would occur. Views of the construction activities would also be from the I residence north of the Kern River across from the proposed intake structure. The grading activities of the intake structure would include excavating into the slope between the river and the existing CALM fenceline area. This excavation is expected to be partially visible from the residence north of the river due to the extensive tree vegetation along the north and south side of the river. The intake structure is -, proposed to be located south of an island that is located near the south bank of the river. The island ,I also include tree vegetation that would obstruct views of construction activities associated with the intake structure. The residence north of the river may also have partial views of construction activities associated with the low lift station and pond. These partial views are not expected to be significantly i" altered. i The proposed project will include construction of the raw water pipeline south along the bike path from Alfred Harrell Highw: ~.' to approximately 0.6 mile north of Paladino Drive and east to the water i treatment plant site. The project also includes the construction of a potable water pipeline from the water treatment plant west to the bike path. At the bike path, a 16-inch potable water pipeline is proposed to extend north along the bike path to an existing potable water line that is located just north i of the proposed Hart Memorial Park Also the bike 36-inch pipeline. conveyance at path, potable water pipeline is proposed to extend south to Paladino Drive, east to Morning Drive and south to i Panorama Drive. These water pipelines will result in similar short-term visual impacts as construction i of the bike path occurs. The existing motorists along Alfred Harrel Highway, visitors at the Kern County Soccer Park and CALM, and residences north of Paladino Drive would experience views of ! 02160007.EIR. doc V. 7-5 Aesthetics ! Northeast BakersfieM Bike Path and Water Facilities - Draft EIR construction activities associated with the water pipelines; however, these views would be of relatively distant and/or non-intensive construction activities. The existing uses near the intersection of Panorama Drive and Morning Drive include a church and a school. Views from these two uses of the proposed project would be limited to construction activities associated with a pipeline along Morning Drive south of Paladino Drive. The primary alteration of view from these two uses would be construction activities near the intersection of Morning Drive and Panorama Drive. Since construction activities associated with the pipeline would occur during a relatively short time frame in the vicinity of these two uses, views from these uses are not expected to be significantly altered during construction. Grading at the proposed water treatment plant site is expected to occur over an approximately 20 to 24-week period throughout the 40-acre site. Due to the undulating terrain, a portion of the water treatment plant site is visible from the residences that are located southwest of the water treatment plant site. TherefOre, a portion of the grading activities will be viewed from these residences. Due to the partial visual obstruction from the undulating terrain, views from these residences of grading activities on the w~ter treatment plant site would not be significantly altered. Other residences that are located south, and ,southeast of the water treatment plant site will have minimal views and due to the distance of these views, no significant alteration to their views would occur during construction activities. Construction activities associated with the proposed access road from the existing pavement on Paladino Drive to 'approximately 0.3 mile to the west to the proposed bike path, north approximately 0.6 mile, and then east to the proposed water treatment plant site will alter views from the existing residences east of the access road. When combined with the visual impacts from construction of the bike path and piPeline,, the visual impact of constructing the access road is not expected to be significant due to the non-intensive construction activities and the visual distance to the activities from the adjacent residences. Long-term Impacts Bike Path The implementatiOn of the proposed bike path will result in an increase in bicyclists in northeast Bakersfield. The permanent bike path (12-foot asphalt section), it's related directional signs, and the increase use by bicyclists are not expected to result in significantly altering the long-term views of the project area (i.e., views from Alfred Harrell Highway, the Kern County Soccer Park, CALM, the residences north of Paladino Drive and east of the bike path, and the residences near Fairfax Road). The connections of the proposed bike path to Fairfax Road and Alfred Harrell Highway would be at the roadway grade 'level and would not result in significant visual impacts, 02160007.EIR. doc V.7-6 Aesthetics Northeast Bakersfield Bike Path and Water Facilities - Draft EIR Water Facilities Implementation of the water facilities north of Alfred Harrell Highway is not expected to result in significant long-term adverse impacts on views of this area. The largest water facility feature proposed north of Alfred Harrell Highway is the reservoir pond. Due to the existing topography, a levee will be developed to create the pond. Soil that is excavated from the pond area is expected to be used to create a levee. The northwest to northeast side of the levee will have a height of approximately 2 to 12 feet with the highest portion of the levee facing the Kern County Soccer Park and the Kern River. The southwest to southeast side of the levee will have a height of approximately 2 to 4 feet. The southwest to southeast side of the levee will be gradually sloped to the edge of the pond. The levee as well as the perimeter of the pond and surrounding lands will be landscaped to enhance a natural appearance. The implementation of the pond would provide a natural view and would be compatible with the view of the river. The low lift pump station is proposed on the slope and partially below grade in the vicinity of the existing CALM pump station. The high lift station will include a structure that is approximately 1,400 square feet with a height of 12 feet or less. The structures associated with these pump stations will not result in a significant adverse alteration of existing views. The proposed Hart Memorial Park conveyance pipeline, raw water pipeline, and potable water pipeline will be constructed underground and would not result in a long-term visual impact.' The implementation of the proposed water facilities north of Alfred Harrell Highway will allow the future removal of intake pipes and pumps associated with CALM, the Kern County Soccer Park, and Hart Memorial Park. The removal of these three sets of facilities would enhance the long-term views along the river. The implementation of the proposed water treatment plant will include structures that may extend up to 30 feet above the ground. Due to the undulating terrain, views of the structures will be partially obstructed from the existing residences that are located southwest of the water treatment plant site. The perimeter of the water treatment plant will be landscaped to provide visual relief of the proposed structures. With the implementation of landscaping and the expected non-intensive character of the water treatment plant structures, views from the residences southwest of the plant site are not expected to experience a significant and adverse alteration. Views from other residences that are located south and southwest of the water treatment plant site are not expected to be significantly altered due to the undulating terrain and distance of the views. Furthermore, the implementation of the proposed access road to the water treatment plant site will increase vehicular traffic in the project area. This increase in a of approximately to employees plus periodic deliveries vehicular traffic will include maximum 20 30 to the water treatment plant. This increase in daily activity will contribute to the significant adverse visual affect of the water treatment plant from the two residences that are located southwest of the water treatment plant site. 02160007.EIR. doc V.7-7 Aesthetics Northeast BakersfieM Bike Path and Water Facilities - Draft EIR V. 7.3 CUMULATIVE IMPACTS Development of the proposed project and related projects would result in urbanizing rural areas and result in the loss of open space in the northeast Bakersfield area. The proposed project would result in affecting views from two existing residences that are located in the vicinity of the proposed water treatment plant Site; however, these would not be significantly altered. The views from these residences would not be further impacted with the development of the related projects because these projects are not located in close proximity of these two residences. Therefore, the proposed project would not contribute to cumulative aesthetic and visual impacts. V.7.4 MITIGATION MEASURES Even though no significant visual impacts would occur with the implementation of the water facilities, the following measures are recommended to further reduce the alterations of existing views. AES-1. Prior to the issuance of a grading permit, the City will prepare a landscape plan for the area north of Alfred Harrell Highway to provide visual relief of the project features. The landscape plan shall be approved by the County of Kern. AES-2 Prior to the issuance of a grading permit, the applicant shall submit a landscape plan for review and approval by the City for the proposed water treatment plant to provide visual relief of the proposed structures. V.7.5 LEVEL, OF SIGNIFICANCE AFTER MITIGATION No significant aesihetic impacts would occur with the implementation of the proposed bike path and water facilities. 02160O07.EIR.doc V.7-8 Aesthelics ~ ' Nor&east Bakersfield Bike Path and Water Facilities - Draft EIR V.8 PUBLIC HEALTH AND SAFETY l' The following discussion addresses issues of public health and safety as they relate to the project study area. These issues include the potential exposure of construction workers to soil and/or groundwater contamination related to the potential presence of chemicals associated with historic uses (e.g., oil production facilities) within the project area; handling, disposal, and potential for upset associated i with the transport, storage, and use of hazardous materials by the proposed water treatment facility; and the potential hazard to recreational rafters from the intake structure proposed along the Kern River. ~!~ V.8.1 EXISTING CONDITIONS I Hazardous Materials and Waste ~ll Hazardous materials and the generation of hazardous waste generally raise environmental concern when altering, changing, .or developing uses (e.g., industrial or commercial uses). Hazardous I materials can take the form of petroleum products (including oil and gasoline) from automobile use ' and oil production activities, automotive fluids (antifreeze, hydraulic fluid), paint, cleaners (dry cleaning solvents, cleaning fluids), pesticides from agricultural uses (if in significant concentrations), I in addition to those chemicals (i.e., ferric chloride, aluminum sulfate, polymers, sodium hypochlorite, · caustic soda, zinc orthophosphate, powdered activated carbon and potassium permanganate) that would be used to treat water at the proposed water treatment facility. By-products generated as a result of activities using hazardous materials, such as dry cleaning solvents, oil and gasoline, etc., are considered to be hazardous waste. Contamination usually takes the form of a hazardous materials or waste spill in soil. Such contamination could penetrate through the soil to the groundwater table, resulting in the pollution of the local water supply. Commercial uses, particularly those using ! underground storage tanks (USTs), are most suspect for such contamination. However, with ~ remediation techniques currently in practice, soil contamination typically does not pose a serious health risk, unlike contamination of groundwater. To determine the presence of and potential for hazardous materials and/or waste contamination within i the project area from existing and historical uses, a review of databases maintained by federal, state, and local regulatory agencies was conducted. A complete listing of databases reviewed is provided in f. Appendix E. CEQA requires the lead agency to consult the lists of hazardous waste sites compiled by I various state agencies (the California Environmental Protection Agency [EPA], the Department of Health Services, the State Water Resources Control Board, and the California Integrated Waste i Management Board) pursuant to Governmental Code Section 65962.5 (CEQA, Cal.

These facilities are located approximately 800 feet north of Paladino Drive approximately 2,000 feet east of Morning Drive. A number of abandoned oil production facilities are also located throughout the project area to: the north and south of Paladino Drive. V.8.2 PROJECT IMPACTS Thresholds of Significance An unauthorized ~elease of hazardous material and/or waste that results in the contamination of the environment or the exposure of people to hazardous materials and/or waste in excess of regulatory limits would be Considered a significant impact. This would include the exposure of construction workers to hazardous materials and/or waste encountered during the excavation of contaminated soils and/or groundwater. A significant impact would also occur if the project resulted in exposure of people to other potential health risks beyond acceptable levels. Potential Sources' of Contamination Implementation of the proposed project would include the development of a water treatment plant. This use would involve the long-term transport, storage, and use of chemicals for water treatment pUrposes, resulting in the potential for hazardous materials and/or waste contamination to occur. The project will result in a greater potential for an unauthorized release of hazardous materials and/or waste to occur. However, the proposed water treatment plant would be required to comply with all exiting federal, state, and local regulations and guidelines that provide for mechanisms to ensure proper handling (e.g., transport, storage, and use) of hazardous materials, generation of hazardous waste, and treatment of any potential hazardous materials and/or waste incidents. Additionally, Sections 301 through 330 of the federal Superfund Amendments and Reauthorization Act (SARA) of 1986 provides for iCommunity Right to Know (CRTK), which requires business to disclose the use of hazardous materials. The primary intent of CRTK is to ensure that safety measures a~,. emergency response provisions are in place at all such businesses and that such plans are coordinated with local emergency response agencies. The CRTK also provides a mechanism for disclosing to the community the presence and Use of hazardous materials by local business as well as the safety and emergency response measures. in place. Therefore, development of the proposed project is not expected to result in a significant public health and safety impact related to the handling of hazardous materials. 02160007.EIR.doc V. 8-4 Public Health and Safety i Northeast Bakersfield Bike Path and Water Facilities - Draft EIR ,1 -- Oil Production Activities i Due to the presence of existing and historic oil production activities in the project area, there is a potential for hazardous materials and/or waste contamination to be present in shallow soils within the I i project area. Potential impacts resulting from individuals being exposed to these substances, if at all, would occur during grading and construction of the proposed project. It is currently unknown as to the I level of potential contamination in the project area from these activities; however, if contamination is ~- present, it can easily be remediated prior to development of the project using readily available technologies. Therefore, the nature of the contamination in the soils is not considered to be an I immediate public health threat. ,1~ Sites Included on Agency Lists As indicated previously, no known or suspect hazardous materials and/or waste contamination sites Ithat have the potential to contribute to hazardous materials and/or waste contamination were identified on or within the immediate vicinity of the project area. Therefore, no impacts would occur. I Recreational Rafting As indicated previously in Section III of this EIR an intake structure approximately 30-feet wide by 50 feet long by 15 feet high (partially below grade) will be constructed at the edge of the Kern River ichannel at a location north of the facilities that are currently developed as part of CALM. A steel trash screen will be installed across the width of the intake structure to prevent debris from entering the pump station. There is a perception that recreational rafters who utilize the Kern River could be 'l injured by this intake system if, by chance, they fall from their raft. More specifically, water would flow into the intake structure from the Kern River based on gravity flow. Therefore, depending on the t depth and strength of the flow, a recreational rafter could be drawn into the system. However, the trash screen has been designed to include steel horizontal bars with an approximately 3 to 4 inch separation between each bar. This will ensure that injury to recreational rafters is avoided if they are il drawn into the intake structure. Therefore, no significant public health and safety impacts are expected to occur to recreat: ~nal rafters from the intake structure. I V.8.3 CUMULATIVE IMPACTS I Development of the proposed project and related projects will cumulatively increase both the development intensity, population, and traffic in the region, thus exposing a greater number of people i to hazards within the project vicinity. Future projects that will result in exposing the public to such hazards will be required to comply with federal, state, and local regulations and guidelines to reduce the potential for significant public health and safety impacts to occur. Therefore, cumulative i 02160007.EIR. doc V.8-5 Public Health and Safety I Northeast BakersfteM Bike Path and Water Facilit~'es - Draft EIR l, development in the project vicinity is not expected to have a significant impact on public health and safety.

I I '1 I I' I I I Looking across future water treatment plant site toward Ant Hill I I SECTION VI I GROWTH- INDUCING IMPACTS I I Northeast BakersfieM Bike Path and Water Facilities - Draft EIR SECTION VI GROWTH-INDUCING IMPACTS The proposed water treatment facilities are located in an area that is currently outside a water district service boundary. This area also has severely limited groundwater supplies. Existing residences pump groundwater or import water for their domestic use. Due to the lack of available water supply within this area, minimal development has occurred. The implementation of the proposed water facilities will induce growth within the northeastern portion of the City of Bakersfield. By providing a water supply to this area that is currently outside of a water district service boundary, a primary development constraint is substantially reduced. The Metropolitan Bakersfield General Plan has identified the need to provide adequate water supply to serve this northeast area. The proposed water treatment plant will have an initial design capacity of 10 mgd; however, as development occurs, the design capacity will ultimately inci'ease to 60 mgd. The design capacity is expected to be used during summer months which has historically been the peak water usage months. During the non-summer months, the average water use is expected to be approximately 50 percent of peak use. Atter the ultimate capacity is developed approximately 20 mgd will be available to serve future residential growth in northeast Bakersfield. The remaining capacity will be available for existing residences and users. Based on the current General Plan designated land uses within the new northeast service area, approximately 14,900 new dwelling units could be constructed. Based on an average water consumption rate of 328 gallons per day and an average of 2.7 people per unit, the new northeast service area would demand approximately 13 mgd. Under the ultimate buildout of the water treatment plant, there would be approximately 7 mgd available during non-summer months. This water supply could accommodate the development of approximately 7,700 new dwelling units in other undeveloped portions of the City of Bakersfield. Therefore, under ultimate buildout conditions, the proposed water treatment plant could accommodate up to 22,500 new dwelling units. The proposed project (water facilities) would induce development within undeveloped open space areas. This induced development along with the development of the proposed project may result in potential significant growth impacts to environmental resources (e.g., biological, cultural, geologic, etc.) in undeveloped/open space areas. The project's induced development of 14,900 dwelling units in the new northeast Bakersfield water service area would require the introduction of entirely new and/or major extensions of existing transportation/circulation and public service and utility systems such as water and wastewater distribution lines, storm water drainage facilities, and police and fire equipment personnel. 02160007.EIR. doc VI- 1 Growth-Inducing Impacts Northeast BakersfteM Bike Path and Water Facilin'es - Draft EIR Depending on the exact locations of the individual project in relation to existing built-up areas, the project's induced development of the remaining 7,700 dwelling units in other undeveloped portions of the City may require new and/or minor extensions of existing transportation/circulation and public service and utility systems. The Metropolitan Bakersfield General Plan has assumed substantially more growth than 7,700 new dwelling units in areas outside of the new northeast Bakersfield service area and within the City. Therefore, the growth that could be induced as a result of project implementation could occur in areas that are currently designated for development within the General Plan. However, at this time, the location, extent and timing of growth and associated infrastructure systems are currently unknown. These .systems would be implemented on a project-by-project basis for development both within the new northeast Bakersfield water service area and other undeveloped portions of the City of Bakersfield. Measures to reduce potentially significant impacts from the project's induced development to a less than significant level or to the maximum extent feasible would be imposed with each new development until the entire 14,900 units in the new northeast Bakersfield water service area is built-out and the additional 7,700 units are dex/eloped within other undeveloped portions of the City. Therefore, although the project would result in inducing future growth in these areas, specific impacts associated with the growth itself would be the responsibility of the future individual projects. Following is a detailed discussion of the type of growth inducing effects that could occur with the implementation of the proposed water facilities. These effects would occur within the new northeast Bakersfield water service area and throughout other undeveloped portions of the City of Bakersfield. VI.1 EARTH The project's induced development in the new northeast Bakersfield water service area and in undeveloped portions of the City may result in potentially significant impacts to earth resources. More specifically, four major fault systems are location in the vicinity of the City that could cause such impacts as strong ground shaking, fault rupture, liquefaction, and earthquake-induced landslides and dam failure. These .potential impacts would be reduced to less than significant levels through compliance with appropriate seismic' design criteria from the Uniform Building Code. This future growthlcould also result in erosion and sedimentation impacts during construction activities. However, implementation of City-required erosion control features, in the development of these dwelling units would reduced these impacts to less than significant levels. The topography w{thin the new northeast Bakersfield water service area includes rolling hills. Future growth within this area could result in impacts to the topography. These potential impacts could be reduce through adherence with the City's grading ordinance. The topography within the remaining 02160007.EIR.doc VI-2 Growth-Inducing Impacts Northeast Bakersfield Bike Path and Water Facilities - Draft E1R portions of the City are relatively flat and future development outside of the new service area and I within the City is not expected to result in significant topography impacts. VI.2 WATER Hvdroloev and Drainage .I~ Future development associated with the project's induced development would result in potentially significant landform alterations and new surface areas, including compacted fills, landscaping, and I impervious surfaces. As indicated previously, the new northeast Bakersfield water service area is primarily undeveloped; therefore, future development within the area would significantly increase the il amount of impervious surfaces. This increase in impervious surfaces would require a system of storm water conveyance facilities. Additional storm water conveyance facilities may be required to serve the additional growth that would be developed throughout the City of Bakersfield. Regardless, the City of Bakersfield Public Works Department and the Kern County Flood Control District i would ultimately review the design of these drainage systems. Design requirements of these two agencies · . would ensure that runoff is properly conveyed and discharged. Therefore, impacts associated with storm water drainage fi.om the project's induced development of are considered less than significant. It Water Supply Future development associated with the project's induced growth would increase the need for a water distribution system. The proposed project could provide potable water to future development within I the northeast Bakersfield area; however, a water distribution system will be required to serve the · growth. As individual projects are developed, water needs would be assessed to determine appropriate i water distribution systems to be implemented. With the buildout of the proposed water treatment ' ' plant, no significant long-term impacts on water supply in the northeast Bakersfield area is expected to occur. Water Quality During grading and construction of the project's induced development, there will be a potential of surface water runoff to carry sediment and small quantities of pollutants in the storm water drainage system. More specifically soil erosion may occur during construction and in areas where temporary soil storage is required. Small quantities of pollutants, such as oil or other fluids used for construction, have the i potential for entering the storm drainage system, thereby degrading the water quality. 02160007. EIR. doc VI-3 Growth-Inducing Impacts ! Northeast BakersfieM Bike Path and Water Facilities - Draft EIR Upon development of these units, land surface erosion would be significantly reduced due to the increase in pavement and other non-erodible surfaces. However, development activities would increase the 1 potential for storm water nmoff to transport surface water quality contaminants from roadway surfaces, lawns, driveways, parking lots, and other exposed structural and landscape surfaces into the storm drain systems, i Future development associated with the project's induced growth would be required to comply with federal (e.g., National Pollution Discharge Elimination System), state, and local requirements and implement best management practices to reduce the effects on surface watery quality to less than I' significant levels or the maximum extent feasible. VI.3 AIR QU/~LITY The project's induced development would result in potentially significant short-term air quality impacts. More specifically, development of these dwelling units would produce emissions from construction equipment, fugitive dust, and asphalt paving for several years. Exhaust emission from construction include emissions associated with the transport of machinery and supplies to and from the construction sites, emission produced onsite as the equipment is used, and emissions from tracks transporting excavated materials from construction sites and fill soils to constmction sites. Future development associated with the project's induced growth would also result in potentially significant long-term regional impacts, which include emissions emitted from stationary and mobile sources. More specifically, electricity and natural gas is utilized by almost every residential development. Energy consumption emissions are emitted through the generation of electricity and consumption of natural gas. Mobile sources refer to emissions from motor vehicles, including tail pipe and evaporative emissions. Because insufficient data are available regarding short-term construction (e.g., types of equipment, etc.) and long-term operational activities (e.g., project trip generation, traffic flow conditions, etc.) for the future induced growth, such emissions cannot be quantified. Rather, this data would not be available until specific projects are undertaken. As individual residential projects are developed within the new northeast Bakersfield water service area and the other undeveloped portions of the City, impacts on air quality will be assessed and appropriate mitigation measures will be required to reduce these impacts to less than significant levels or.. the maximum extent feasible. VI.4 BIOLOGICAL RESOURCES The project's induced development may result in potentially significant impacts to sensitive plant and · ammal species (including rare and endangered species). More specifically, conversion an,~' ]evelopment 02160007.EIR. doc : VI--4 Growth-Inducinglm/~acts Northeast BakersfteM Bike Path and Water Facilities - Draft EIR of natural vegetation found within the new northeast Bakersfield water service area and the other undeveloped portions of the City of Bakersfield would have the potential to contribute to a population decline for several plant and wildlife species. Depending on their location, construction of future developments could be covered under the Metropolitan Bakersfield Habitat Conservation Plan (MBHCP). The goal of the MBHCP is to acquire, preserve, and enhance native habitats, which support endangered and sensitive species, while allowing urban development to proceed as set forth in the City's General Plan. The plan generally takes a broad ecosystem approach on conservation of endangered species and requires a development fee to be paid. These fees are used for the acquisition and management of lands for conservation which are held in perpetuity. The MBHCP does not eliminate the need to consider species under CEQA, but it does establish programmatic mitigation for project impacts on endangered species. Compliance with the MBHCP will reduce impacts on sensitive plant and wildlife species from the project's induced development to less than significant levels. VI.5 TRANSPORTATION The future growth associated with the project's induced development may result in potentially significant short-term construction and long-term operational traffic impacts. The City of Bakersfield has established a transportation impact fee program for urban areas within the City of Bakersfield. The fee program (Metropolitan Bakersfield Transportation Impact Fee program) is to provide intersection and roadway segment improvements as development occurs within the City. As individual projects are developed within the new northeast Bakersfield water service area and the other undeveloped portions of the City, traffic-related impacts would be assessed and appropriate mitigation measures (e.g., payment of fees) would be required to reduce these impacts to less than significant levels or the maximum extent feasible. VI.6 CULTURAL RESOURCES Potentially significant impacts on known and unknown cultural resources may occur from the project's induced growth. Such resources include fossils, remains, and artifacts from prehistoric civilizations, historic structures, and other antiquities. As individual projects are developed within the new northeast Bakersfield water service area and the other undeveloped portions of the City, impacts on cultural resources would be assessed and appropriate mitigation measures (e.g., testing and salvage, etc.) would be required to reduce these impacts to less than significant levels or the maximum extent feasible. 02160007.EIR. doc VI-5 Growth-Inducing Impacts I Northeast Bakersfield B,ke Path and Water Facilities- Draft EIR VI.7 LAND USE Future growth associated with the project's induced development may result in the loss of prime agricultural farml,and. Due to the magnitude of the potential loss of such farmland, a significant unavoidable adverse impact is expected to occur. Depending on their location, development of the 22,500 umts may also result in potentially significant impacts related to land use compatibility with existing and planned land uses and consistency with relevant plans and policies (e.g., City of Bakersfield General Plan, etc.). As individual projects are developed within the new northeast Bakersfield water service area and the other undeveloped portions of the City, land use :impacts would be assessed and appropriate mitigation measures would be required to reduce these impacts to less than significant levels or the maximum extent feasible. VI.8 PUBLIC SERVICES AND UTILITIES VI.8.1 POLICE PROTECTION SERVICES : FutUre growth associated with the project's induced development of approximately 22,500 units may result in potentially significant impacts on police protection services and facilities. More specifically, development of these dwelling units could result in an increase in population that could require an expansion of thes~ services with the new northeast Bakersfield water service area and throughout the remaining undeveloped portions of the City. Previously, the City of Bakersfield retained a ratio of 1.65 police officers per 1,000 residents. This average was recently reduced to 1.5 officers per 1,000 residents, the standard for a city its size. Using a standard of 1.5 sworn officers per 1,000 people, development of 1.4,900 dwelling units in the new northeast Bakersfield water service area could require 60 new police officers. Future growth associated with .the project's induced development of 7,700 dwelling units within other undeveloped portions of the City may also result in the need for increased police protection services within these areas. Increased population growth within these other undeveloped portions could result in a demand of 31 inew police officers. .-; As individual projects are developed within the new northeast Bakersfield water service area and other undeveloped portions of the City, police protection service impacts would be assessed'in accordance with ' CEQA and appropriate mitigation measures (e.g., additional services and facilities) may be required to reduce these impacts to the maximum extent feasible. 02160007.EIR. doc VI-6 Growth-Inducing Impacts Northeast BakersfteM Bike Path and Water Facilities - Draft EIR VI.8.2 FIRE PROTECTION SERVICES Future growth associated with the projeCt's induced development of approximately 22,500 dwelling units may result in potentially significant impacts on fire protection services and facilities. More specifically, the new northeast service area encompasses approximately nine miles. Each fire square station in the City of Bakersfield currently serves a nine square mile area. Therefore, development of the 14,900 dwelling units in the new northeast Bakersfield water service area may require a new fire station. The city currently has 1.031 fire fighters per 1,000 residents. Using its current ratio as a standard for future growth, the city may need 41 new fire fighters to service the new northeast Bakersfield water service area. Future growth associated with the project's induced development of 7,700 dwelling units within other undeveloped portions of the City may also result in the need for 21 new firefighters. It is currently unknown whether or not any new fire-related facilities will be needed in areas outside the new northeast service area. As individual projects are developed within the new northeast Bakersfield water service area and other undeveloped portions of the City, fire protection service impacts would be assessed in accordance with CEQA and appropriate mitigation measures (e.g., additional services and facilities) may be required to reduce these impacts to less than significant levels or the maximum extent feasible. VI.8.3 SCHOOLS Future growth associated with the project's induced development of approximately 22,500 dwelling units result in potentially significant impacts on school services and facilities. More specifically, may in the City of Bakersfield, school districts can impose a maximum fee of $1.50 per square foot of new homes and $0.25 per square foot of commercial and industrial developments (State law AB2926). Current estimates for number of students generated per housing unit are .365 for grade k through 6, .093 for grades 7 and 8, and .209 for grades 9 through 12. Using these estimates, the 14,900 dwelling units that could be developed in the new northeast Bakersfield water service area could generate a total of 9,885 new students (K-6 = 5,410, 7-8 = 1,378, 9-12 = 3,098). The average public school in the City of Bakersfield has approximately 667 students enrolled. Therefore, approximately, 14 new public schools may be needed to accommodate the additional 9,885 students. Future growth associated with the project's induced development of 7,700 dwelling units within the undeveloped portions of the City may result in an increase of 5,158 students. Therefore, approximately 8 new schools may be needed to accommodate these students. 02160007.EIR. doc VI -7 Growth-Inducing Impacts Northeast BakersfieM Bike Path and Water Facilities - Draft E1R As individual projects are developed within the new northeast Bakersfield water service area and other undeveloped portions of the City, fire protection service impacts would be assessed in accordance with CEQA and approPriate mitigation measures (e.g., additional services and facilities) may be required to reduce these impacts to less than significant levels or the maximum extent feasible. VI.8.4 PARKS/RECREATION Future growth associated with the project's induced development of approximately 22,500 dwelling units may result, in potentially significant impacts on parks/recreation services and facilities. the City of Bakersfield retains approximately 2.1 acres of park and recreation area for every Presently, 1,000 residents. In order to retain this ratio with the development of approximately 14,900 dwelling units within the new northeast Bakersfield service area, 84 acres of land would need to be dedicated to park and recreation areas. Future growth associated with the project's induced development of approximately 7,700 dwelling units within otherlundeveloped portions of the City may create a demand for 44 additional acres of park and recreation areas. As individual, proj~, cts are developed within the new northeast Bakersfield water service area and other undeveloped portiOns of the City, parks/recreation service impacts would be assessed in accordance with CEQA and appropriate mitigation measures (e.g., additional services and facilities) may be required to reduce these impacts to less than significant levels or the maximum extent feasible. VI.8.5 SOLID WASTE DISPOSAL Future growth ass6ciated with the project's induced development of 22,500 dwelling units may result in potentially' significant impacts on solid waste disposal services and facilities. The Shafier-Wasco and Bena landfills ~are the closest solid waste disposal facilities to the new northeast Bakersfield water service area as well as to the City of Bakersfield as a whole. The Bena landfill had 7.3 million cubic yards and the Sha~er-Wasco had 3.2 million cubic yards of remaining capacity in 1994, according to the Kern County Waste Management Department's Source Reduction and Recycling Element (dated August 16, 1994). ~ The average person in the Bakersfield metropolitan area produces 1.8 tons of solid waste per year. The project's potential inducement of approximately 14,900 dwelling units in the new northeast Bakersfield area may result in the generation of 720,300 tons of solid waste per year. The project's potential inducement of an additional 7,700 dwelling units within the other undeveloped portions of the City of Bakersfield may result in the generation of 37,724 tons per year of solid waste. 02160007.EIV,.ao¢, VI-8 Growthdnducing Impacts Northeast Bakersfield Bike Path and Water Facilit~'es- Draft EIR The increase in solid waste generation in the new northeast Bakersfield water service and other undeveloped portions of the City may require the need for additional solid waste services and facilities. As individual projects are developed within the new northeast Bakersfield water service area and other undeveloped portions of the City, solid waste impacts would be assessed in accordance with CEQA and appropriate mitigation (e.g. need for additional services and facilities) measures may be required to reduce these impacts to less than significant levels or the maximum extent feasible. VI.9 UTILITIES VI.9.1 WASTEWATER Future growth associated with the project's induced development of approximately 22,500 dwelling units may result in potentially significant impacts on wastewater services and facilities. The new northeast Bakersfield water service area is currently not within an existing wastewater district. The daily production of wastewater capita in the City of Bakersfield is 100 gallons day. average per per Based on this estimate, the project induced development of approximately 14,900 dwelling units in the new northeast Bakersfield water service area would generate 4 million gallons per day (mgd) of wastewater. This increase in wastewater generation would require new wastewater services and facilities to be developed in this area. Future growth associated with the project's induced development of approximately 7,700 dwelling units in other undeveloped portions of the City of Bakersfield could result in the generation of 2 mgd of wastewater. This increased generation of wastewater may require the development of new wastewater services and facilities within these areas of the City. As individual projects are developed within the new northeast Bakersfield water service area and other under, eloped portions of the City, wastewater impacts would be assessed in accordance with CEQA and appropriate mitigation measures (e.g. need for additional services and facilities) may be required to reduce these impacts to less than significant levels or the maximum extent feasible. VI.9.2 STORM DRAINAGE See Section VI.2 above for a discussion of the impacts on storm drainage facilities. VI.9.3 NATURAL GAS Future growth associated with the project's induced development of approximately 22,500 dwelling units may result in potentially significant impacts on natural gas services and facilities. There are two providers of natural gas for the City of Bakersfield, Pacific Gas and Electric and Southern California 02160007.EIR. doc VI-9 Growth-Inducing Impacts Northeast Bakersfield Bike Path and Water Facilit~'es - Draft EIR Gas Company. Pacific Gas and Electric currently serves the area that encompasses the new northeast Bakersfield water service area. Annual consumption in the City of Bakersfield is 9,125 cubic feet per year per residential unit. Future growth associated with the project's induced development of approximately 14,900 dwelling units in the new northeast Bakersfield water service area would result in the consumption of 135 million cubic feet (mcf) per year of natural gas. This increase would require the need for additional natural gas services and facilities in this area. Future growth associated with the project's induced development of approximately 7,700 dwelling units in other undeveloped portion of the City could result in the consumption of 71 mcr per year of natural gas. This increase may result in the need for additional natural gas services and facilities to be developed within these areas of the City. As individual projects are developed within the new northeast Bakersfield water service area and other undeveloped portipns of the City, natural gas impacts would be assessed in accordance with CEQA and appropriate mitigation measures (e.,g need for additional services and facilities) may be required to reduce these impacts to less than significant levels or the maximum extent feasible. VI.9.4 ELECTRICITY Future growth associated with the project's induced development of approximately 22,500 dwelling units may result in potentially significant impacts on electrical services and facilities. Pacific Gas and Electric (PG&E) is the sole provider of electricity for the City of Bakersfield. Since 1982, PG&E has had an annual growth rate of 3.5 percent. Although they have had problems in the past with blackouts in the summer months in the City of Bakersfield, major improvements have been recently made to their service. Average annual cOnsumption of electricity for the City of Bakersfield is 5,750 kilowatts per year per residential unit. Future growth associated with the project's induced development of 14,900 dwelling units in the new northeast Bakersfield water service are would result in an increased consumption of 85 million kilowattS (mkw) per year of electricity. This increase would require the development of additional electrical services and facilities within this area. Future growth associated with the projects induced development of approximately 7,700 dwelling units within other undeveloped portions of the City would result in a consumption of an additional 45 mkw per year of electricity. This increase may require the development of additional electrical service and facilities within these areas of the City. 02160007.EIR. doc: VI - 10 Growth-Inducing Impacts Northeast BakersfieM Bike Path and Water Facilities - Draft EIR As individual projects are developed within the new northeast Bakersfield water service area and other undeveloped portions of the City, electricity impacts would be assessed in accordance with CEQA and appropriate mitigation measures (e.g. need for additional services and facilities) may be required to reduce these impacts to less than significant levels or the maximum extent feasible. VI.9.5 COMMUNICATION Pacific Bell is the sole provider of telephone service in the City of Bakersfield. Currently, Pacific Bell has an annual growth rate of 16 percent, 60 percent of which is residential, and are continually improving their transmission lines and carriers. According to the Final Environmental Impact Report for the Metropolitan Bakersfield 2010 General Plan, dated September 1989, Pacific Bell does not anticipate any impediments to expanding service to accommodate growth throughout the City. Therefore, future growth associated with the project's induced development is not expected to result in potentially significant impacts to communication services and facilities. VI.10 POPULATION/EMPLOYMENT/HOUSING Future growth associated with the project's induced development would result in an increase in housing opportunities within the new northeast Bakersfield water service area (14,900 units) and other undeveloped portions of the City (7,700 units), primarily as a result of in-migration. This would result in a secondary increase in employment and population within the City and surrounding area. However, the City of Bakersfield General Plan and other regional growth plans have assumed this increase in population, employment, and housing and have planned accordingly as it relates to public services and facilities, traffic and circulation, and other infrastructure requirements. Moreover, as individual projects are developed within the new northeast Bakersfield water service area and other undeveloped portions of the City, population, employment, and housing impacts would be specifically assessed in accordance with CEQA and appropriate mitigation measures (e.g., need for additional services and facilities) may be required to reduce these impacts to less than significant levels or the maximum extent feasible. VI.Il HEALTH HAZARDS Future growth associated with the project's induced development within the new northeast Bakersfield water service area and other of the would result in health undeveloped portions City potentially significant hazard impacts during construction activities. More specifically, development of these dwelling units may result in the exposure of construction workers to b~?ardous materials encountered during grading activities. As individual projects are developed within the new northeast Bakersfield water service area and other undeveloped portions of the City, potential health hazard impacts on construction workers 02160007.EIR. doc VI- 1 1 Growth-Inducing Impacts Northeast BakersfieM Bike Path and Water Facilities - Draft EIR would be assessed in accordance with CEQA and appropriate mitigation measures may be required to reduce these impacts to less than significant levels or the maximum extent feasible. Future growth could include the construction of new transportation and circulation facilities. These facilities may introduce the transport of bo?ardous materials to areas that are previously unexposed to such materials, increasing the risk of transportation accidents involving baTardous materials within the new northeast Bakersfield water service area and other undeveloped portions of the City. The threats posed by a transportation accident involving ha?;ardous materials includes explosions, physical contact by emergency response personnel, and airborne exposure of the public to contaminants. However, numerous federal, state, and local polices and regulations regarding the transport ofh~rdous materials are currently in place. Therefo[e, the risk of a potential unauthorized release of baTardous materials during transport would be considered adverse but not significant. Moreover, development of these dwelling units would also introduce substances ranging from household products (e.g., paints, cleaners, landscape maintenance productions) to regulated materials used within neighborhood commercial sites. Applicable federal, state, and local agencies would regulate these substances; therefore, the development of these dwelling units would not be expected to pose a significant health risk. VI.12 NOISE Future growth assOCiated with the project's induced development would result in potentially significant short-term noise impacts. More specifically, development of these dwelling units would produce noise emissions from co.nstmction equipment during earthrnoving, materials handling, stationary, and impact equipment and vehicles generating noise during clearing, excavation, grading, structure, roadway and utility construction operations assOCiated with the development of these dwelling units. Future development would also result in potentially significant long-term regional noise impacts, which include emissions emitted from mobile sources. More specifically, future development would add traffic and/or proposed roadway segments in the new northeast Bakersfield water service area and to existing other undeveloped, portions of the City, casing traffic noise levels to increase along these roadway segments. Because insufficient data are available regarding short-term construction and long-term operational activities for future growth, noise emissions cannot be quantified. This data would not be available until specific projects are undertaken. As individual residential projects are developed within the new northeast Bakersfield water service area and other undeveloped portions of the City, noise impacts will be assessed and appropriate mitigation measures (e.g., noise walls) will be required to reduce these impacts to less than significant or the maximum extent feasible. 0216000'7 .EIR.doc VI - 12 Growth-Inducing Impacts Northeast BakersfteM Path Water - Draft Bike and Facilities EIR VI.13 AESTHETICS/LIGHT AND GLARE Future growth associated with the project's induced development may result in potentially significant aesthetic/light and glare impacts. More specifically, development of these units would significantly alter the nature and appearance of the new northeast Bakersfield water service area and may significAmtly alter other undeveloped portions of the City that would be gradually transforming fxom existing undeveloped, rural land to a mix of residential uses. In addition, future development may result in short-term view impacts due to the grading of these areas and the presence of construction equipment and building materials. After completion of construction, view impacts may be perceived because of the alteration of any natural landforms and the presence of urban structures in the place of open space. While the change in appearance of the new northeast Bakersfield water service area and other undeveloped portions of the City would be largely subjective, this change could be perceived by some individuals to result in a significant unavoidable adverse impact, while others may not perceive the visual changes as significant or adverse. As individual residential projects are developed within the new northeast Bakersfield water service area and other undeveloped portions of the City, aesthetic impacts will be assessed and appropriate mitigation measures (e.g. landscaping, contour grading, etc.) will be required to reduce these impacts to less than significant or the maximum extent feasible. Moreover, future development is expected to introduce new sources of light and glare. More specifically glare would result fi.om lights and the sun reflecting off windows and shiny, metallic surfaces. It is also assumed this development will introduce new light sources from signage, street lighting, and vehicular traffic. General increases in light could be expected to significantly increase the ambient evening light level in the new northeast Bakersfield water service area and other undeveloped portions of the City. The induced development of residential uses would be particularly sensitive to increases in light; however, setbacks and standard mitigation (shielding of lights, use of low intensity lights, etc.) would reduce potential impacts on these residents to less than significant levels. VI.14 NATURAL RESOURCES Future growth associatea 'with the project's induced development, will result in the reduction of land l. available for oil production, including the Kern Bluffarea. The loss of potential oil production land in the new northeast Bakersfield water service area (e.g., along the future alignment of Paladino Drive) and I other undeveloped portions of the City is not expected to significantly affect the availability of these oil resources because there are some areas that are currently designated for mineral petroleum uses in the I General Plan Land Use Element. These areas could be used for continued oil production activities. i I 02160007.EIR. doc VI- 13 Growth-Inducing Impacts Northeast BakersfieM Bike Path and Water Facilia'es - Draft E1R VI.15 ENERGY USAGE Future growth associated with the project's induced development will result in the use of energy in the form of electricity, natural gas, and fuel during construction activities and for long-term needs of residents. The increase in energy use resulting from this induced development may result in a significant use of existing energy resources. Consequently, the development of these dwelling units may significant affect local and/or regional existing energy supplies. Section VI.9.3 and VI.9.4 above identifies the amount of electricity and natural gas that would be consumed as a result future growth associated with the project's induced development. As individual residential projects are developed within the new northeast Bakersfield water service area and other undeveloped portions of the City, impacts on energy use will be assessed and appropriate mitigation measures (e.g., conservation methods, etc.) will be required to reduce these impacts to less than significant or the maximum extent feasible. !

Section V. 1 through Section V.8 of this EIR provide a description of the potential environmental impacts of the proposed project, as well as measures to reduce the significant environmental impacts to the extent feasible. Section VI provides a discussion of the potential growth-inducing impacts associated with the proposed project. No feasible measures or alternatives are available to reduce the potential significant growth-inducing impacts of the proposed project. After the implementation of the mitigation measures, all but two impacts related to the proposed project would be reduced to a less than significant level. These significant unavoidable adverse impacts are: · Short-term Air Quali_ty: Construction activities would result in significant emission of oxides of nitrogen. After the implementation of the mitigation measures, emissions of oxides of nitrogen would continue to exceed the annual threshold established by the San Joaquin Valley Air Pollution Control District. Growth-Inducement: Implementation of the proposed water facilities would significantly induce development within northeast Bakersfield. This induced development would result in significant impacts on existing service and utility systems as well as significant impacts on existing the environment. ! 02160007.EIR. do¢ VII-1 Significant Unavoidable Adverse Impacts I I I I I I I' I I I i Looking northeast at furore intake structure site I !

SECTION VIII i ALTERNATIVES TO THE PROPOSED PROJECT I I Northeast BakersfieM Bike Path and Water Facilities - Draft EIR SECTION VIII ALTERNATIVES TO THE PROPOSED PROJECT Section 15126(d)(2) of the state CEQA Guidelines, as amended, mandates that an EIR include a comparative evaluation of the proposed project with alternatives to the project, including the No Project alternative. As described in Section III, Project Description, the proposed project is the implementation of a bike path and water facilities. This section focuses on alternatives to the proposed project capable of avoiding or substantially lessening any significant adverse impacts associated with the proposed project even if these alternatives would impede to some degree the attainment of project objectives or be more costly. Additionally, alternatives are discussed in the terms of achieving project objectives (see Section III of this EIR). The EIR has focused on the direct and indirect effects on the environment which will result from implementation of the proposed project. Direct environmental impacts of the project would occur to water resources, biological resources, land use, short-term air quality, short-term noise, cultural resources, aesthetics, and public health and safety. Except for impacts associated with short-term air quality, all direct impacts are ~ither not significant or not significant after the implementation of mitigation measures. The project-related alternatives evaluated in this section are based on locating the proposed water treatment plant and associated water pipelines to alternative sites. The purpose to focus on relocating the water treatment plant is because the project's significant unavoidable adverse air quality impact is primarily associated with the grading operations on the water treatment plant site. The project alternatives evaluated in this section include the no project alternative and three alternative sites. The Environmentally Superior Alternative will be selected from among these alternatives and the proposed project. An alternative that is environmentally superior will result in the fewest or least significant environmental impacts and will achieve the objectives of the planning effort. Based on the evaluation of the four altematives in this section, implementation of the No Project Alternative would result in fewer significant impacts than the proposed project. While this alternative is seemly environmentally superior than the proposed project, it would not meet the objectives for the proposed project and CEQA does no require the No Project Alternative to be identified as the environmentally superior alternative. Therefore, this alternative is not proposed as the project. The analysis of alternatives includes the assumption that all applicable mitigation measures associated with the project will be implemented with the appropriate alternatives. However, applicable mitigation measures may be scaled to reduce or avoid the potential impacts of the alternative under consideration, and may not precisely match those identified for the proposed project. 02160007.EIR. doc VIII-1 Alternatt'ves to the Proposed Project Northeast Bakersfield Bike Path and Water Facilities - Draft EIR Table VIII-1 provides a comparative summary of impacts between the proposed project and each project alternative. A description of each alternative and a comparative environmental evaluation of the environmental effects are provided below. VIII. 1 NO PROJECT ALTERNATIVE DESCRIPTION The No Project Alternative assumes that no bike path or water facilities would be implemented in the northeast Bakersfield area. IMPACT EVALUATION This alternative would result in no new environmental impacts. The significant unavoidable air quality and growth inducing impacts associated with the construction of the proposed project would be avoided under this alternative because no new development would occur. The potential impacts associated with water resources, biological resources, land use, noise, cultural resources, aesthetics, and public health and safety would also not occur under this alternative. Furthermore, this alternative would not provide the benefits of the project. These benefits include a connection of a bike path from Fairfax Road to Hart Memorial Park and new water facilities. The water facilities can provide a more reliable source of~water to existing recreational uses north of Alfred Harrell Highway and a new domestic water source for existing and future development in the northeast portion of the City of Bakersfield.

The location of the bike path and a majority of the water facilities would be the same as under the proposed project. The water treatment plant Would be located within a 40-acre area north of and adjacent to Paladino Drive between the north to south alignment of the bike path and the existing terminus of Moming Drive at Paladino Drive. IMPACT EVALUATION Water Resources Under this alternative, the implementation of the bike path and a majority of the water facilities would result in the same' storm water runoff impacts as the proposed project. Similar to the proposed project, grading associated with the water treatment plant under this alternative is anticipated to alter drainage patterns, This alternative would increase surface water flows to the west to east drainage channel that is located approximately 0.4 mile north of Paladino Drive. This increase in flows could result in significant long-term erosion and sedimentation into the natural drainage channel. However, with the implementation of a similar mitigation measure as the proposed project (i.e., a storm water retention structure on the project site that allows historical storm flows to be conveyed offsite), no significant erosion or sedimentation would occur. Similar to the proposed project, this alternative would provide a beneficial impact to existing recreational uses north of Alfred Harrell Highway by providing a more reliable water supply. This alternative would also result in a less than significant impact related to withdrawing water from the Kern River for future growth and existing users. This alternative Would result in slightly less surface water quality impacts during construction activities compared to the proposed project because this alternative would require less construction. The access road to the water treatment plant would not be as long under this alternative compared to the proposed project. With less construction activities, there would be less of a potential to degrade the quality of surface water compared to the proposed Project. Similar to the proposed project, this alternative could implement the recommended mitigation measures to reduce the potential significant surface water quality impacts to less than significant. Similar to the proposed project, this alternative would result in less than significant long-term surface water quality impacts. However, due to a shorter length of the access road, there is a potential for less ' 02160007.EIR. doc VIII-6 Alternate'yes to the Proposed ?roject Nor&east Bakersfteld Bike Path and Water Facilities - Draft EIR typical urban pollutants to runoff off of the access road. Therefore, this alternative would result in less long-term surface water quality impacts. Overall, this alternative would result in less impacts on water resoUrces than the proposed project. Biological Resources Development of the project components under this alternative would result in significant impacts on biological resources. As with the proposed project, this alternative would affect non-native grassland, valley saltbrush scrub, and riparian habitat, and special status plant and wildlife species. Implementation of the project mitigation measures would reduce potential significant impacts associated with this alternative to a less than significant impact. Overall, this alternative would result in the same impacts on biological resources as the proposed project. Land Use Plans and Policies Due to potential soil contamination, implementation of the proposed water treatment plant could be incompatible with the existing and past oil facility uses on the alternative site. However, if there is soil contamination on the alternative site, the contamination would be required to be remediated prior to implementing the water treatment plant. Therefore, implementation of the proposed water treatment plant on Alternative Site A would be compatible with the surrounding uses. Similar to the proposed project, the implementation of the proposed water treatment plant would also require a General Plan amendment. This alternative would require an amendment from general commercial to public facility. Similar to the proposed project, this alternative would include a General Plan amendment, and therefore, would be consistent with the designated uses on the water treatment plant site. Similar to the proposed project, this alternative would be consistent with the plans, policies, and programs that are applicable to the proposed project. Overall, this altemative would result in similar land use impacts as the proposed project. Air Quality (Short-term) As with the proposed project, this alternative would result in short-term construction air emissions. This alternative would result in the generation of fugitive dust (PM10), reactive organic compounds (ROG), and oxides of nitrogen (NOx) during construction activities. This alternative includes a shorter access road compared to the proposed project, and therefore, less grading is required. Since this alternative would require less grading, less construction emissions (PM10, ROG, and NOx) would 02160007.EIR. doc VIII-7 Alternatives to the Proposed Project Northeast Bakersfield Bike Path and Water Facilities - Draft EIR be generated compm-ed to the proposed project. Even though less construction emissions would be generated, this alternative would still generate significant and unavoidable NOx emissions. Overall, this alternative would result in less short-term air quality impacts compared to the proposed project. Noise {Short-term) The implementation of Alternative Site A would result in short-term construction noise impacts on sensitive land useS in the vicinity of the alternative site. The nearest residence to the water treatment plant site under this alternative is approximately 1,000 feet. Construction noise levels generated from the water treatme,nt plant site under this alternative would be approximately 73 dBA at the nearest residence. Under the proposed project, noise levels from construction activities associated with the water treatment plant site would be approximately 80 dBA. Neither the proposed project nor Alternative Site A would result in significant construction noise impacts. Overall, this alternative would result in less noise impacts compared to the proposed project. Cultural Resources Implementation of this alternative may result in potential impacts to archaeological/historical and paleontological resources. Similar to the proposed project, potential impacts to a mine shaft along the proposed bike path and water pipeline south of Alfred Harrell Highway may occur during construction activities. Furthermore, potential impacts to paleontological resources associated with the Sharktooth Hill bonebed may'occur during grading activities. Overall, this alternative would result in the same potential significant impacts to cultural resources as the proposed project. Implementation of the project mitigation measures would reduce potential impacts to a less than significant level. Aesthetics Alternative Site P~ would result in short-term and long-term visual impacts. Unlike the proposed project, the implementation of the proposed water treatment plant facilities under this alternative would not be partially obstructed by the natural terrain. Construction activities on Alternative Site A could be viewed from the nearest residence as well as the existing school and residences located along Panorama Drive. Views of construction activities on this alternative site are not expected to be significantly altered. Long-term views of the water treatment plant will include structures that may extend up to 30 feet above the ground. These views could be significantly altered. Landscaping ' adjacent to these ifacilities could reduce' long-term visual impacts. The implementation of this alternative is not expected to result in significant long-term aesthetic impacts after the implementation of landscaping. Overall, the proposed water treatment plant under this alternative is expected to be more visible than the plant under the proposed project. Therefore, this alternative would result in greater aesthetic impacts compared to the proposed project. 02t6000?.ETR. aoc VIII-8 dlternat~'ves to the Proposed t>roject Nor&east BakersfteM Bike Pa& and Water Facilities - Draft EIR Public Health and Safety Similar to the proposed project, implementation of this alternative would result in potentially significant impacts with the transport, use, and storage of chemicals for the water treatment plant operations. This alternative would also result in similar potential impacts (although less than significant) to recreational rafters from the operation of the proposed intake structure compared to the proposed project. Furthermore, due to existing and historic oil production activities north and south of Paladmo Drive, this alternative would result in the same potential significant health impacts to construction workers from grading and construction activities of the proposed bike path and pipeline along Paladino Drive compared to the proposed project. Unlike the proposed project, this alternative would result in potential significant haelth impacts to construction workers from grading and construction activities associated with the proposed water treatment plant. Overall, this alternative would result in greater public health and safety impacts than the proposed project. CONCLUSIONS . The potential impacts to biological resources, land use, and cultural resources would be the same as the proposed project. Impacts related to water resources, short-term air quality, and short-term noise would be less than the proposed project. However, impacts to aesthetics and public health and safety would be greater than the proposed project. Due to the relative similarities in impacts associated with this alternative and the proposed project and a sensitivity of aesthetic and visual impacts in the project area, the proposed project is considered to have less overall impacts compared to this alternative. Therefore, this alternative is not environmentally superior to the proposed project. This alternative would, however, meet the objectives of the proposed project, set forth in Section III.3. VIII.3 ALTERNATIVE SITE B DESCRIPTION This alternative would include the same location of the bike path and a majority of the water facilities. The water treatment plant proposed under this altemative would be located on approximately 40 acres and would be on a plateau approximately 3,000 feet west of the water treatment plant proposed under the proposed project. An access road as well as the proposed raw and potable water pipelines would extend to the water treatment plant along an existing dirt access road located 0.5 mile approximately north of Paladino Road. 02160007.EIR. doc VIII-9 Alternatives to the Proposed Project Northeast BakersfteM Bike Path and Water Facilities - Draft EIR I IMPACT EVALUATION I Water Resources Under this alternative, the implementation of the bike path and a majority of the water facilities would result in the same storm water runoff impacts as the proposed project.

Similar to the proposed project, this alternative would result in less than significant long-term surface water quality impacts. However, due to a slightly longer access road, there is a potential for more typical urban pollutants to runoff of the access road. Therefore, this alternative would resUlt in more long-term surface water quality impacts. Overall, potential impacts on water resources from the implementation of this alternative would be slightly greater impacts than the proposed project. Biolotical Resources Development of the project components under this alternative would result in significant impacts on biological resources. As with the proposed project, this alternative would affect non-native grassland, valley saltbrush scrub, and riparian habitat, and special status plant and wildlife species.

Overall, this alternative would result in the same impacts on biological resources as the proposed project. Land Use Plans and Policies Similar to the proposed project, the bike path and water facilities under this alternative would be compatible with the surrounding land uses. The implementation of the water treatment plant at the alternative site would require a similar General Plan amendment to redesignate the site from low density residential to public facility. Similar to the proposed project, this alternative would be consistent with the plans, policies, and programs that are applicable to the project. Overall, this alternative would result in similar land use impacts as the proposed project.

Due to a slightly longer access road, this alternative would result in slightly greater construction emissions (i.e., PM10, ROG, and NOx) compared to the proposed project. Similar to the proposed project, this alternative would also generate significant and unavoidable N0x emissions. Overall, this alternative would result in slightly greater short-term air quality impacts compared to the proposed project. Noise (Short-term) The implementation of Alternative Site B would result in short-term construction noise impacts on sensitive land uses in the vicinity of the alternative site. The nearest residence to the water treatment plant site under this alternative is approximately 1,600 feet. Construction noise levels generated from the water treatment plant site under this alternative would be approximately 68 dBA at the nearest residence. Under the proposed project, noise levels from construction activities associated with the water treatment plant site would be approximately 80 dBA. Neither the proposed project nor Alternative Site B would result in significant construction noise impacts. Overall, this alternative would result in less noise impacts compared to the proposed project. Cultural Resources Implementation of this alternative may result in potential impacts to archaeological/historical and paleontological resources.

Aesthetics Altemative Site B would result in short-term and long-term visual impacts. Unlike the proposed project, the implementation of the proposed water treatment plant facilities under this alternative would not be partially obstructed by the natural terrain. Construction activities at the water treatment Alternative Site B could be viewed from the nearest residence, similar to the proposed plant on project. Views of construction activities on this alternative site are not expected to be significantly altered.

This alternative would also result in similar potential impacts (although less than to recreational rafters from the operation of the proposed intake structure compared to the significant) proposed project.

CONCLUSIONS The potential impacts to biological resources, land use, cultural resources, and public health and safety would be the same as the proposed project. Impacts related to short-term noise would be less than the proposed project. However, impacts to water resources, short-term air quality, and aesthetics would be greater than the proposed project.

This would represent a long-term commitment pump toward urbanization since the potential for the land reverting back to undeveloped land is minimal due i to the demand for increased water supply in the northeast Bakersfield area. The future growth that would be induced by the proposed project (see Section VI) would potentially I reduce oil production in the area by committing existing undeveloped land to residential and commercial development. This would represent an irreversible and irretrievable environmental i - change. Nonrenewable resources would be committed, primarily in the form of fossil fuels, and would include I ' fuel oil, natural gas, and gasoline for vehicles used in the construction and subsequent use of the site. The consumption of other nonrenewable and slowly renewable resources would result from i . development of the project site. These resources would include, but would not be limited to, the · following: lumber and other forest products, sand and gravel, asphalt, petrochemical construction materials, steel, copper, lead, and water. Because alternative energy sources such as solar or wind Ienergy are not currently in widespread local use, it is not likely that a real saving in nonrenewable energy supplies (i.e. oil and gas) could be realized in the immediate future.

PROJECT CHARACTERISTICS The proposed project includes the construction of a bike path and water facilities (water treatment plant, pipeline, reservoirs (ponds), pump stations, and intake channel) in the northeast portion of the City of Bakersfield. Following is a detailed description of the project components. Bike Path Approximately 3.7 miles of bike path is proposed to connect Fairfax Road to Alfred Harrell Highway. The proposed bike path will connect with the County of Kern's bike path that is located adjacent to Alfred Harrell Highway, Hart Memorial Park, and CALM. The bike path will primarily follow the future alignments of Paladino Drive and Morning Drive. The bike path will consist of a 16-foot-wide asphalt concrete section with a bike lane centerline delineated and graded shoulders. Water Facilities The proposed project also includes a number of water facilities to serve an area in northeast Bakersfield that is not currently served by a water district. The water facilities include the diversion of water from the Kern River to a proposed water treatment plant located east of Morning Drive approximately 0.5 mile north of Paladino Drive. A description of each facility is discusse below. Kern River Diversion and Low Lift Pump Station- A reinforced concrete intake structure approximately 30-feet wide by 50 feet long by 15 feet high will be constructed. Starting at the edge of the Kern River channel at a location north of the facilities currently developed as part of CALM. A steel trash screen will be installed across the width of the intake structure to prevent debris from entering the pump station. At the end of the intake structure, a sand removal and ejection system will collect sand from the intake water and return it to the River downstream of the intake structure. The intake water will then gravity flow through two 200-foot long buried reinforced concrete pipes, WJB\02160007.IS.DOC 1-2 Project Description Northeast BakersfieM Bike Path and Water Facili.ty Initial Study approximately 42 inches in diameter each, discharging to a pump station wet well. The wet well will be a reinforced concrete structure approximately 20 feet long by 40 feet wide by 20 feet high, located near the existing CALM raw water reservoir. The end of the wet well will contain a series of pumps with the ability to pump water at various flow rates, discharging into an unlined canal. The pump station site will also have a small housing for electrical service, switch gear, and motor controls. The unlined canal will convey the water from the pump station to the raw water ponds. Raw Water Ponds - A new raw water reservoir covering approximately 15 acres of surface area will be constructed just south of the Kern River between the future Morning Drive alignment to the west, the existing CALM site to the east, and Alfred Harrel Highway to the south. The reservoir will provide a dual purpose: (1) impounding raw water for the water treatment plant, and (2) incorporate the reservoir into CALM's conceptual plan as "ponds". A series of ponds will be constructed in a free form shape to create a natural appearance. The perimeter of the ponds and surrounding lands will be landscaped to enhance a natural appearance. A 12-foot wide gravel all-weathered access road will be constructed around the perimeter of the ponds. This road will provide access to the river diversion, pump stations, Hart Memorial Park turnout, and pond sites. Hart Memorial Park Turnout and Conveyance - The existing water source for the lakes within Hart Memorial Park is a rock and boulder diversion dam across the Kern River. The dam diverts water to an unlined canal, which conveys the water from the river to Hart Memorial Park. The existing rock and boulder dam is a physical barrier across the width of the river, except for a short bypass on the northerly side. This physical barrier affects recreational activities (such as floating on the river on raxS~s). In its current condition, when there is low flow in the river, no water is diverted into the canal. This situation requires pumping with a portable pump to maintain a minimum flow into the canal and to the park lakes. The new diversion and conveyance facilities for Hart Memorial Park would eliminate the need for the rock and boulder diversion structure in the Kern River. A slide gate controlled turnout structure will be installed on the northwest reservoir embankment. This turnout would connect to a pipeline (to be constructed by the County) with a flow meter downstream. The pipeline would run approximately 5,000 feet from the reservoi.' .o the Hart Memorial Park canal along the northerly boundar 9fthe Kern County Soccer Park. The flow meter structure, located downstream from the turnout, would measure flow with an indicator located at the turnout structure. High Lift Pump Station - A pump station to deliver the raw water from the ponds to the proposed treatment plant will be constructed on the CALM site at the southwest end of the ponds and adjacent to the future Morning Drive alignment. This pump station will consist of a series of pumps able to deliver the raw water to the proposed treatment plant at various flow rates and an elevation difference of approximately 350 feet. The discharge pipe will have a flow meter located just downstream of the wm~o216oooT.ls. Doc 1-3 Project Descrip~'on Northeast Bakersfield Bike Path and I~'ater Facility Initial Stu~. pump station. A flow indicator and a totalizing (volume) recorder will be located at the pump station. The pump station would be constructed slightly below grade to partially screen views of the facilities and to minimize the length of pump casing. The height of the pump station will not exceed 35 feet above the existing grade. The area of land required for the high lift pump station and related facilities such as electrical power and switch gear housing is approximately 14,000 square feet (approximately 0,3 acre). Water Treatment Plant - The water treatment plant is proposed on approximately 40 acres southwest of Ant Hill, approximately 0.5 mile north of Paladino Drive. The water tre2.tment plant is proposed to initially produce 10 mgd of drinking water. As growth continues in the northeast the area, treatment plant would be increased in size to a maximum of 60 mgd. The plant will include buildings that will house treatment processes, water treatment chemicals, laboratory facilities, pumping equipment, and administrative functions. These buildings may extend up to 30 feet above the ground. The facility will also include open basins of water that will provide both storage and treatment functions. Partially buried water tanks will also be located on the site. Buildings and basins storage on the treatment site will be connected by a road network for access. The water treatment plant site will be accessed offof Paladino Drive. The treatment plant will be connected to the water pipeline that will be constructed under the bike path alignment to Morning Drive. Water Pipeline - A 54-inch water pipeline is proposed to extend from the high lift station to the pump proposed water treatment plant. The pipeline will be located along the proposed bike path for approximately 4,000 feet south of Alfred Harrell Highway and then the pipeline will extend to the southeast to the proposed water treatment plant site. From the water treatment plant, a 36-inch pipeline is proposed to return to the bike path with treated water. Other transmission lines will be constructed as required for future development. At the bike path, a 16-inch pipeline is proposed to extend north along the bike path and a 36-inch pipeline is proposed to extend south along the bike path. The 16-inch pipeline will extend to the CALM facility for future use by CALM as well as future development south of the Kern River. The 36-inch pipeline is proposed to extend south of the water treatment plant along the proposed bike path to Paladino Drive. The pipeline will continue to extend south from Paladino Drive to the southern of Section 18 29 South and boundary of Township Range 29 East, which is approximately 600 feet north of Highway 178. North of Highway 178, the 36-inch water pipeline will extend west to an existing 18-inch water pipeline at the Morning Drive/Panorama Drive intersection, which extends west along Panorama Drive to the existing water tanks in the system. The connection between the proposed water treatment plant and the existing water tanks along use existing water storage capacity to serve Panorama Drive will allow direct of the northeast residents.

X WJB~02160007.1S.DOC 2-1 Environmental Checklist Northeast BakersfieM Bike Path and Water Facili.tv Initial Study SECTION 3 DISCUSSION OF ENVIRONMENTAL IMPACTS EARTH Soils - Based on the United States Department of Agriculture's "Soil Survey of Kern County, California: Northwestern Part", the project site includes a variety of soil types due to the linear nature of the proposed project. The soil t).~es include: riverwash, Hesperia sandy loam, Premier coarse sandy loam, Xeric Torriorthents, stratified-Cuyama complex, Delano sandy loam, and Cuyama loam. The characteristics of these soil types include moderate to moderately rapid permeability and well-drained soils. The majority of the project site has relatively flat terrain and these areas are not expected to result in significant erosion. Portion of the proposed bike path will be located in relatively steep terrain in the vicinity of the Fairfax Road/Paladino Drive intersection and through the canyon area between Alfred Harrell Highway and Paladino Drive. Furthermore, the proposed water treatment plant will be located on east to west sloping terrain approximately 0.5 mile north of Paladino Drive. The portion of the proposed project with relatively steep terrain will be designed with erosion control features as required in the City's grading ordinance. Implementation of these features would result in less than significant erosion impacts. Grading activities will include trenching for the pipelines, scraping for the bike path, excavation for the raw water storage, and cut/fill for the water treatment plant, intake structure, and pipeline connection with the unlined Hart Memorial Park canal. The characteristics of the soils throughout the project site are not expected to significantly affect the engineering of the proposed bike path or water facilities. Geologic Hazards - The project area is seismically active. Seismic hazards include strong ground shaking, fault rupture, liquefaction, earthquake-induced landslides and dam failure. Other geologic hazards include landslides and land subsidence. Four major fault systems are located in the vicinity of the City. The four faults are the San Andreas, Breckem'idge-Kern Canyon, Gariock, and White Wolf faults. The maximum credible earthquake in the vicinity of the City could occur along the San Andreas Fault. The San Andreas Fault has a maximum credible earthquake (Richter Magnitude) of 8.0-8.3, and is located approximately 3545 miles southwest of the project site. The Breckenridge- Kern Canyon Fault has a maximum credible earthquake of 6.0-8.0, and is located approximately 20 miles east of the project site. The Garlock Fault has a maximum credible earthquake of 7.~ &0, and is approximately 30 miles southwest of the project site. The White Wolf Fault has a maximum credible earthquake of 7.5-8.0, and the primary fault line is located approximately 15 miles southeast of the project site. In 1952, there were significant ground ruptures due to movement along the White Wolf Fault. Movement along this fault resulted in damage to many older buildings in Bakersfield. According the "Geologic Hazards" map within the Metropolitan Bakersfield 2010 General Plan, surface ground rupture occurred in close proximity of the project site. Current development standards will require compliance with appropriate seismic design criteria from the Uniform Building Code wmx02160007.1s.~oc 3-1 Discussion of Environmental Impacts Northeast BakersfieM Bike Path and Water Facili.tv Initial Study (UBC). The [IBC seismic design criteria will reduce potential seismic hazards to a less than significant level. Erosion/Sedimentation - Development of the proposed project could result in erosion and sedimentation during construction activities. The portions of the project site that have a higher potential for erosion and sedimentation include the relatively steep hill in the vicinity of the future Fairfax Road/Paladino Drive intersection, the canyon area between Alfred Harreli Highway and Paladmo Drive, the intake structure at the Kern River, and the pipeline connection to the unlined Hart Memorial Park canal. The remaining areas of the project site have relatively flat terrain and are not expected to result in significant erosion or sedimentation. The portions of the project site with the potential for erosion and sedimentation will be designed with control features as required in the City's grading ordinance. For those portions of the project erosion that are within County of Kern jurisdiction, the erosion control features will be designed as required in the County's grading ordinance. No significant differences in the design features between the City's ordinance and the County's ordinance are expected. Implementation of the erosion control features are expected to reduce potential erosion and sedimentation to a less than significant level. Tooo~raphy - Implementation of the proposed bike path and water pipeline would not result in a significant alteration of the existing topography. The raw water reservoir located north of Alfred Harrell Highway will alter the topography due to the excavation of soil needed to create the proposed ponds. Furthermore, the proposed water treatment plant is proposed on the southwest side of Ant Hill; however, the water facilities are proposed to be partially underground to reduce the effect on the existing topography. Implementation of the proposed project is not expected to significantly alter the topography of the project area. WATER Water Quality and Quantity - Following is a discussion of the project's potential impact on groundwater quality and quantity and surface water quantity and quality. Short and long term impacts will be addressed in the EIR. Groundwater - Constructic' activities associated with the development of the proposed project are not expected to affect the groundwater. The proposed project would not alter the direction or rate of flow, intercept an aquifer by cuts or excavations, or result in direct additions or withdrawals of groundwater resources. Surface Water - Implementation of the proposed project will result in the withdrawal of surface water from the Kern River at the intake structure. No net effect on current farmers or other water users will occur downstream because the use of Kern River water upstream will only reduce the of excess water from the Kern River that is currently directed into the City's 2,800-Acre amount wmxo2~60oo'rmr~oc 3-2 Discussion of Environmental Impacts ! Northeast BakersfieM Bike Path and Water Facility Initial Study I Groundwater Recharge Facility. The recharge facility is located approximately eight miles west of Highway 99. During the dry season, the City would pump water from the 2,800-Acre Groundwater I Recharge Facility to ensure that the water users in the down-river portions receive their surface water allocation. The EIR/EA will include a more detailed discussion of the long-term net effect from the I use of Kern River water for the proposed project. Construction activities associated with the proposed project may result in short-term water quality I impacts. These impacts will be discussed in the EIR/EA. Long-term impacts on surface water quality would primarily occur from the addition of automobile trips associated with the operation of the water treatment plant and maintenance trips for the proposed bike path and water facilities. Since the proposed water treatment plant is expected to have relatively few employees at the plant site (approximately 20 to 30 employees) and maintenance activities are expected to be periodic, no long-term impacts on surface water quality is expected. Furthermore, the water pipeline that is proposed to convey raw water to the unlined Hart Memorial Park Canal will be a similar quality as the existing water within the canal. With the canal's new water source, the existing water diversion dam will not require annual replacement. In a few years after the conveyance of raw water to the Hart Memorial Park canal, the diversion dam will be washed away. The natural removal of the diversion dam would reduce the long-term scouting of the north bank of the Kern River across from the existing dam. This reduction of scouring will result in a beneficial impact of the surface water quality of the Kern River. Flood Drainage - The 100-year flood plain is located immediately adjacent to the Kern River. The low lift pump station is proposed in an area that would be inundated during a 100-year flood event. Other areas of the project site that are located along the Kern River include a bike path, underground water pipeline, and raw water reservoirs. These facilities may be inundated during a 100-year flood event; however, no significant impacts would occur. These facilities would remain operational and/or be operational after the lO0-year flood event occurs. The proposed bike path may require maintenance activities after a flood event. No other areas of the project site are within the lO0-year flood zone. A further discussion of flooding will be provided in the EIR/EA. AIR Air Quality - The proposed project will result in short-term and long-term air emissions. Short-term air emissions will result from construction activities. Long-term air emissions will result from the proposed water treatment plant, low lift pump station, and highlift pump station. Potential significant short-term air emissions may occur during project construction activities and these emissions will be further discussed in the ElS/EA. Long-term emissions from the water treatment facilities, employees traveling to and from work, and the pump stations are not expected to exceed the San loaquin Valley Air Pollution Control District's recommended significance thresholds for ozone precursors ,oxides of WJB\021600(}7.IS.DOC 3-3 Discussion of Environmental Impacts Northeast Bakersfield Bike Path and Water Facili~ Initial Study nitrogen and reactive organic gases) which is 10 tons per year for each precursor. No significant long- term air emissions are expected to occur with the implementation of the proposed project. Climate/Air Movement - Materials and equipment used in the construction of the proposed project, and the operation of the bike path and water facilities would not result in the alteration of air movement, moisture, temperature, or any climatic change. Odors - The proposed water treatment plant, low lift pump station, and high lit~ pump station may create objectionable odors. These potential impacts will be addressed in the EIR/EA. BIOLOGICAL RESOURCES Plants~ Animals~ and Rare/Endangered Species - The proposed project may result in significant impacts to sensitive plant and animal species (including rare and endangered species). These potential impacts on biological resources will be addressed in the EIR/EA. Habitat Alteration - The proposed project will alter habitat on the project site. This alteration may be significant and will be addressed in the EIR/EA. TRANSPORTATION Traffic/Circulation - Implementation of the proposed project will result in short-term construction and long-term operational traffic. Construction activities will be phased; however, the specific phasing schedule has not yet been determined. Traffic related to construction activities is expected to be the most intense related to the proposed water treatment plant. The proposed water treatment plant facilities will be located within a 40-acre site. The plant will include buildings that will house treatment processes, water treatment chemicals, laboratory facilities, pumping equipment, and administrative functions. The facility will also include open basins of water that will provide both storage and treatment functions. Partially buried water storage tanks will also be located on the site. The facilities within the water treatment plant will also be phased to meet future water demand in the northeast portion of the City of Bakersfield. Due to relatively iow existing traffic volumes along Paladino Drive, construction traffic is not expected to significantly affect circulation. The construction traffic along other roadways such as Fairfax Road, Morning Drive, Alfred-Harrell Highway, and Panorama Drive during construction of other components of the proposed project is expected to be nominal compared to the existing traffic along these roadways. The proposed project will result in long-term traffic associated with employees of the water treatment plant and maintenance activit cs associated with the bike path and proposed water facilities. The wmxo2~6oooT.ls.t)oc 34 Discussion of Environmental Impacts Northeast BakersfieM Bike Path and Water Facili.tv Initial Study proposed water treatment plant is expected to have approximately 20 to 30 employees which will result in nominal traffic volumes on the surrounding street network. Maintenance activities for the bike path and water facilities will be periodic and therefore, traffic volumes will be nominal. No significant long-term traffic or circulation impacts are expected to occur with the implementation of the proposed project. Parkint - The proposed project would not affect existing parking areas. Adequate onsite parking spaces will be provided for employees of the water treatment plant. Traffic Hazards - The implementation of the proposed project will not result in a significant amount of traffic during construction and operational activities. Furthermore, no significant increase in potential traffic hazards is expected to occur with the project. The proposed bike path will be physically separated from existing roads and will be designed to extend under Alfred Harrell Highway. AirD,Vater/Rail Systems - No waterborne, rail, or air traffic would be affected by the implementation of the proposed project due to the absence of these systems in the project area. CULTURAL RESOURCES Archaeological/Historical - Archaeological and historical resources may be located on the project site. An evaluation of potential resources will be provided in the EIR/EA. LAND USE Compatibility Except for the proposed water treatment plant, the remaining project components would be compatible with existing surrounding land uses. The water facilities (i.e., intake structure, pump stations, raw water reservoir) proposed in the vicinity of CALM are expected to be compatible with the ammals that are at CALM. The existing animals are within cages in the eastern portion of the CALM area. In the future, CALM is anticipating to plan an area adjacent to the proposed raw water storage for large animals. At that time, fencing of the raw water reservoir will be required. The electrical and motor controls ,'.?the pump stations will be located within a structure so that noise will be minimized. These facilities are also expected to be compatible with the existing soccer fields as well as the existing County bike path. The proposed bike path and pipeline will extend through existing open space and oil facilities and the area is currently designated as One Family Dwelling- Zone in the City's Zoning Ordinance. The bike path and pipeline will be compatible with the existing uses as well as future residences. Odor emissions associated with the proposed water treatment plant may result in compatibility impacts. These effects will be addressed in the EIR/EA. WJ'B~02 ! 60007. IS. DOC 3-5 Discussion of Environmental Impacts Northeast BakersfieM Bike Path and Water Facili.tv Initial Stu~. The water treatment plant is proposed in an area that is within an agricultural preserve. According to the Agricultural Preserve Standard Uniform Rules as adopted by various Kern County Board of Supervisors resolutions, the construction of water facilities are compatible with an agricultural preserve. Therefore, the construction of the proposed water treatment plant would not affect the current agricultural preserve designation on the project site. General PlarffZonin~ The portion of the project site that is located north of Alfred-Harrell Highway is located within a Recreational Forestry' (RF) District under the County of Kern Zoning Ordinance and a Open Space (OS) designation under the Metropolitan Bakersfield 2010 General Plan. The RF District allows both "large water systems" and "water storage and groundwater recharge facilities" as permitted uses. Therefore, the proposed intake structure, pump stations, raw water reservoir, and the Hart Memorial Park turnout and conveyance facilities would be allowed within the RY' District. The portion of the project site that is located south of Alfred-Harrell Highway is primarily One Family Dwelling Zone (R-l) with two small areas designated for commercial (C-2). The proposed bike path and pipeline are allowed in R-1 and C-2 zones. The proposed water treatment plant site is located within an area that is designated R-1 in the Zoning Ordinance and Open Space (OS-S) in the City's General Plan. R-I zones conditionally allow public utility or public service buildings. Therefore, the proposed water treatment plant is conditionally permitted within the R-1 zone. Growth Inducement. The proposed project will provide a domestic water source in the northeast portion of the City which may result in significant growth inducing impacts. The potential growth inducing impacts resulting from the implementation of the proposed project will be discussed in the EIR. Prime Agricultural Land Loss. The proposed project will not affect designated prime agricultural land because the project site does not have soil characteristics of prime agricultural land. No agricultural activities occur in the proposed project area therefore, no impacts to agriculture will occur. PUBLIC SERVICES Police. The implementation of the proposed project will improve public access to the project site. This improved public access may result in an increased demand for police protection services; however, this potential increase is not expected to be significant due to the type of activity (i.e., bike path and water facilities). Fire. Due to electrical equipment at the proposed pump stations and water treatment plant, there would be an increased risk of fire in the project area compared to existing conditions. This increased risk may result in an increased need for fire protection services. However, this potential risk would be WmXO216OOOT.IS.DOC 3-6 Discussion of Environmental Impacts ! Northeast BakersfieM Bike Path and Water Facili.tv Initial Stu~. I reduced with the implementation of Cits.'- and County-required fuel modification zones around the pump stations and water treatment plant. The proposed pump stations and water treatment plant as I well as the proposed bike path and other water facilities would not result a significant demand for in water services. I Schools. The development of the proposed bike path and water facilities would not directly result in a demand for school facilities and no schools are located on or adjacent to the project site. Therefore, I the project would not impact school facilities. I Parks/Recreation. The implementation of the proposed bike path would provide recreational opportunities in the project area. The proposed Hart Memorial Park turnout and conveyance will improve the reliability of water to the Hart Memorial Park lakes. Furthermore, this provision of water I would eliminate the need to periodically repair the existing rock and boulder dam that is located within the Kern River. The natural elimination of the existing dam would eliminate impacts on existing Kern I River recreational activities (i.e., inner tubing and floating down the river on rafts). The remaining components of the proposed project would not create any demand on recreational uses. Overall, the proposed project would result in a beneficial impact on recreational uses. I Solid Waste Disposal. Solid waste is expected to be primarily generated at the proposed water ItrealJnent plant. The generation of solid waste is expected to occur from the operation of the facility. The daily average solid waste generation from the operation is expected to be nominal and no impacts to existing landfills are expected to occur. I Facility Maintenance. Implementation of the proposed project will not result in the need to I significantly alter maintenance activities for public facilities. UTILITIES I Water. Implementation of the proposed project will result in a beneficial impact on water supplies in I the northeast portion of the City of Bakersfield. No adverse impacts would occur. Wastewater. A nominal amount of wastewater is expected to be generated by the employees of the I water treatment plant. The amount of wastewater generated from employee use is not expected to be significant. Initially, wastewater may be collected by an onsite septic tank and conveyed to a disposal I field. This system is expected to be replaced when a sewer system is extended into the area to meet adjacent development needs. No significant effects on existing wastewater systems would occur. I Storm Drainal~e. Implementation of the proposed project is not expected to result in a significant increase in storm water runoff. Portions of the proposed project (i.e., intake structure, pump stations, I and water treatment plant) that will be constructed with impervious surfaces will be r~esigned to wmxo2160007.

Erosion control measures as required in I' the City's and County's grading ordinances will be included in the design to reduce the potential for erosion and sedimentation. No significant impacts to existing storm drains would occur with project l implementation. Natural Gas. I Implementation of the proposed water treatment plant may not require natural gas services during the initial operation of the water treatment plant; however, as development occurs in the vicinity of the water treatment plant, the future facilities at the plant may require natural gas. The future facilities are not expected to create a substantial demand in the project area and gas service could be extended to the water treatment plant site as adjacent development occurs. No significant impacts on existing natural gas service will occur with the implementation of the proposed project. Electricity. Implementation of the proposed intake structure, pump stations, and water treatment plant will require electrical service. These facilities are not expected to create a substantial demand for electricity and not expected to significantly impact existing electrical service in the project area. Communication. Telephone service will be required at the proposed water treatment plant. Based on a projected employment of 20 to 30 people at the treatment plant, no significant telephone service will be required. No significant impacts on existing telephone service is expected to occur with the implementation of the proposed project. POPULATION/EMPLOYMENT/HOUSING Implementation of the proposed bike path and water facilities will not result in a direct increase in population or housing or effect any existing housing. The proposed project will result in a temporary increase in employment during construction activities and minimal long-term employment opportunities (i.e., 20 to 30) at the proposed water treatment facility. The proposed water facilities will result in growth-inducing impacts that will result in indirect increases in population, housing, and employment opportunities. Growth-inducing impacts will be discussed in the EIR/EA. HEALTH HAZARDS The proposed water treatment plant will include the use storage, and handling of chemicals that could cause potential health impac~' These chemicals include ferric chloride, aluminum sulfate, polymers, WmX02160007.1S.DOC 3-8 Discussion of Environmental Impacts Northeast BakersfieM Bike Path and Water Facih.tv Initial Study sodium h~10ochlorite, caustic soda, zinc orthophosphate, powered activated carbon and potassium permanganate. Health impacts will be discussed in the EIR/EA. NOISE Short-term and long-term noise will be generated by the proposed project. Potential significant short- term noise levels may occur during project construction activities and these emissions will be further discussed in the ElS/EA. Long-term noise levels from stationary and mobile sources associated with the water treatment plant and stationary sources at the pump stations are not expected to generate significant noise levels (i.e., increases of more than 3 dBA of the existing ambient noise level) and not expected to exceed the City's noise threshold of 65 dB CNEL for sensitive land uses. No significant long-term noise impacts are expected to occur with the implementation of the proposed project. AESTHETICS The development of the proposed water treatment plant could significantly alter the existing open views of the area from the residential area located west of the plant site. Futhermore, the proposed pump stations and raw water reservoir will alter views north of Alfred Harrell Highway. These impacts will be discussed in the EIR/EA. LIGHT AND GLARE The pump stations and the water treatment facility are expected to have lighting systems. The potential visual effect from these lighting systems will be assessed with the aesthetic impacts. Glare impacts from the proposed facilities are not expected to be significant. NATURAL RESOURCES The project will withdrawl water from the Kem River. The EIR/EA for the project will address hydrological effects associated with the withdrawl of the water. ENERGY USAGE The proposed project will result in the use of energ5 in the form of electricity, natural gas, and fuel during construction activities and for the long-term water treatment facility needs. The increase in energy use resulting from the implementation of the proposed project is not expected to be a significant use of existing energy resources. The proposed project would not significantly affect local or regional existing energy supplies. ! wmx02 ~c, oooT.lS.rX)c 3-9 Discussion of Environmental Impacts I !

We have received a copy of comments on the Notice of Preparation submitted by Fred Simon, Landscapc concur with thc poinls brought out by Mr, Simon regarding County resources. TI~ following additional comments al~ offered to assist the City in prcparing this draft Environmental Impact Report, Section 1 - Project Description Page 1-2 - Kern River Diversion and LoW Lift Pump Station -- Thc statement beginning with the word "Starting" on thc second line of this section is not a complete sentence. Page 1-3 - Raw Water Ponds -- This section needs some additional clarification regarding the matter of one "pond" or several ~ponds." 1~ is our understanding that the latest configul~tion would involve one pond, but ~he write-up refers to a series of ponds. Page I-3 - Hart Memorial Park Turnout and Conveyance -- This section needs to b~ modified to reflect that there will be a separate 12 inch turnout for irrigation water for thc Kern River Soccer Park. In the original thinking ,o.n this matter, Soccer Park water was envisioned as being taken from thc conveyance providing ~r.~tc'r t6 Hart Memorial Park. Instead, there will bc two turnouts constructed, ~ne for Hai't lSar~ an.d a ~pa.rat~ fpcility to se~¢ the Soccer Park. Page 1-4 - Water Pipeline - A modificatioh 6f t~is. v~ri/e~up is requested to clari£y ihat rite County will be able to cermet to thc ~cw l~i indh domestic linc at some future date to obtain potable water sec/icc to meet its requirements at Hart Memorial Park and otht~r Kern River County Park developments such as the Lake Ming arca and the Campground. This same statement could apply to the Soccer Park as well. Certainly, CALM would have future domestic netxls as well, which are already mentioned. Section 3 - Discussion of Environmental Impacts Page 3-1 - Ear~ - Soils -- It is suggested thc discussion under this topic be expanded to address the need for some levee development around the raw water pond. It is our understanding tha!

Page 3-9_ - Earth - Em,ion - The write-up of this section could be strengthened that this project will result in the opportunity to correct an existing erosion hazard created by the cun'ent diveasion for Hart Park water in the Kern Iliwn'. Traffic Hazards It is recommended that this discussion be Page 3-$ Transportation broadened to mention the fact that this project has the potentiM to introduce OllV traffic to thc area along the river and bike trail unless mitigation measures are taken which limit their access to the area. Page 3-5 - Land Use - Compatibility - Given the above discussed change in water source for the Soccer Park, a question about how they might get water late their irrigation system and thc possible need for pumps ari~.s. As has been poh~texl out under the Noise discussion later in the write-up, pump/engine noise may affect the current solitude of the area, and therein, present an impact. This point should be considered in discussing potential impacts. Page 3-9 - Aesthetics - It is suggested this write-up be strengthened by adding discussion concerning the enhancement of the views and the mitigation measures which will be taken to add farther enhanccment~ to what is cun'enfly undcvcIoped land. Certainly, Ihcrc are those who might prefer the area in an undcweloped state, but by using native plants and underground utilities, the visual quality of tho area may definitely be enhanced. The tree planting project along the bike path is scheduled for completion ia November, 1998. The puq:~se of this project is to enhance the undeveloped parkland thxough which thc pathway extends. A portion of the tree planting project will bottler the area proposed for the development of thc raw water pond and the high lift pumping facility. To mitigate thc poss~le hnpact created by this water development, the County suggests thc City contribute trees to this planting project. These trees, which may total up to 200 - 250, planted along this area, would help to ensure the integration of thc proposed water project into the park mvironment and also help ensure protection of bike path character. Any trees contr~uted to the County's planling projecl would be separate from those that might be requested by CALM. We hope these comments will be of assistance in the preparation of the draft EIR, and look fotwanl to continuing to work with City shaffin the development of this exciting project. Robert D.

City of Bakersfield Attention Marc Gauthier ' ~V/A/G' ;~N~,,"° 1715 Chester Avenue Bakersfield, CA 93301 Re: Notice of Preparation of Draft Enviromnental Impact Report, Northeast Bakersfield Bike Path and Water Facilities Ladies and Gentlemen: Pursuant to Agreement No. WR98-14, I have reviewed the Notice of Preparation of Draf~ Environmental Impact Report for the Northeast Bakersfield Bike Path and Water Facilities Project as the action pertains to the California Living Museum (CALM), Kern Soccer Park and Kern County Parks and Recreation Department to the extent requested by that department. It is my understanding that County Parks and Recreation will provide separate and additional comments. CALM is a non-profit zoo and botanic facility holding an 87+ acre lease on property owned by the County of Kern. It is the intent of the City to extract water from the Kern River adjacent the CALM lease and to construct holding ponds, pumping stations and other necessary equipment and facilities on a portion of the CALM lease. Raw water will be provide to CALM, the Soccer Park and the County Parks and Recreation Department for irrigation purposes. Eventually, treated water will be returned from the City treatment facility to provide domestic and commercial water supplies for CALM and other existing and future uses along the Kern River. The project and initial stUdy have been reviewed, and in accordance with the noted agreement, the following comments are submitted. Section I - Project Description The Low Lift Pump Station is described as a 30' wide x 50' long x 15' high structure. The EIR should include a detailed drawing of the structure and elevations to allow reviewers of the document an opportunity to evaluate potential aesthetic effects. The Project Description needs to include a map showing the location of the unlined canal into which water from the wet well will be discharged. The map should also include the width and depth of the canal. The Project Description should indicate whether the Raw Water Ponds will be lined or unlined. It should also indicate the depth of the ponds, and the height and width of any levees needed to contain pond water. A map should be included showing the location of the ponds proposed, and location of the access road and fencing required. American Socie'ly of Landscape Architects ° American Planning Association The High Lift Pump Station is described as being 35' high. It was CALM's understanding that the station would be 3'-4' high. The Project Description needs to describe the height and bulk of this structure, and the architectural design. A map should be included showing the location of the structure, access roads and its relationship to the Raw Water Ponds and the Kern River Bike Path. In addition, the Project Description needs to include a discussion ofbackflow prevention devices proposed as part of the project should the pump station loose power or other occurrence take place. CALM needs to be assured that backflow onto its lease will not inundate the ponds and spill over onto the CALM property. Lastly, the Project Description needs to identify the plant materials that will be planted around the ponds and pump stations. As you know, CALM landscape plantings include only native California plant materials; all materials proposed by the City need to comply with the CALM mission and be approved by CALM. Section 3 - Discussion of Environmental Impacts Water - Groundwater. Impacts indicate that there should be no effect on groundwater fi-om the project. The EIR needs to discuss the depth to ground water at the location of the unlined canal and' ponds (it is assumed the ponds will also be unlined). If groundwater is sufficiently deep, impacts may However, percolation ponds may be minimal. fi.om the alter the natural vegetation along the River, and may also alter the natural and planted vegetation on the CALM property. CALM needs to be assured that percolation will not adversely effect its site. Water - Surface Water. The EIR needs to clarify what will result fi.om removal of water fi-om the Kern River by this project on conditions between CALM and the City's 2,800 acre recharge area during times of low or extremely low flows in the River. Will water still be allowed to flow in the River through the City? How will Truxtun Lake(s) be effected? Will water conditions for holders of riparian rights be affected? Water - Flood Drainage. Discussion of Environmental Impacts indicates that no significant impacts will occur should a 100-year flood event occur. The EIR needs to discuss the conditions of the Raw Water Ponds following such an event, what impacts this might cause on the CALM property, and if any washout fi.om the ponds will effect conditions at CALM. Biological Resources - Habitat Alteration. Discussion of alteration of habitat conditions on the CALM site needs to include effects on resources managed by CALM. This in, ~des the effects on animals at CALM by City maintenance vehicles and personnel, and equipment motors and electrical controls at pump stations (see following comment). Land Use - Compatibility. Discussion of Environmental Impacts note that electrical motors and controls of pump stations will be within buildings to minimize noise. The EIR needs to analyze the effects of noise animals CALM and of the Bike Path on managed by on users (we assume the drone fi-om motors will not effect the enthusiastic users of the Soccer Park). Measures proposed as part of the project and as a introduced in the EIR need to assure 2 CALM that there will be no introduction of noise to the area. CALM supports the use of a concrete vault around all equipment (motors, controls) at the lffi station. Land Use - General Plan/Zoning. The text does not indicate that other elements of the General Plan have been evaluated. It is likely that the Circulation Element shows an extension of Morning Drive through the project and across the Kern River. The EIR should evaluate the potential impacts should that road be constructed. The EIR might suggest that the impact be mitigated by an amendment to the General Plan deleting this road should it be shown to be not needed. Health Hazards. The EIR needs to include discussion relative to impacts of Valley Fever on workers at the site during construction. As you know, animals are also affected by this disease. The possible hazards to animals residing and from visitors at CALM from Valley Fever spores caused by construction activity needs to be evaluated. This section shouid also include a discussion of impacts on the CALM property should a break in water lines between the lift station and treatment plant occur. Aesthetics. The EIR needs to discuss specific design concepts proposed to be followed and how these concepts might effect CALM, Kern Soccer Park and Kern County Parks lands, including the Kern River Bike Path. Areas of concern include the design and width of the access road, including shoulders; fence locations and design; landscape proposals along the raw water pond levee/berm, fences, and access road within the CALM lease; and the design and aesthetic features of the pump stations. Light and Glare. The impacts noted that pump stations are to have a lighting system, but that no significant impact is expected. The EIR needs to analyze the potential impacts to animals on the CALM site from continual lighting of their grazing areas. While the occasional lighting of a soccer field might occur, the continue lighting of the pump station may have a significant effect on animals. We hope these comments will be of assistance in the preparation of the draft EIR. We look forward to reviewing the EIR document and providing ~he City with constructive comments. ,d ruly ~. yours, Fred Simon, ASLA cc: California Living Museum Kern County Parks and Recreation Kern County Superintendent of Schools.

The proposed project is generally located in a rural area within the city limits of Bakersfield in the northeast quadrant of the city. The activities associated with the construction and operation of the proposed project have the potential to impact special status species and their habitat. This report is intended for use by the City of Bakersfield as background data for California Environmental Quality Act compliance. This biological assessment includes: a discussion of the potentially occurring special status plant and wildlife species, survey methods and results, potential impacts to special status species, and mitigation measures intended to minimize impacts to listed species to less than significant levels. Potentially occurring state and federal-listed threatened and endangered species were the focus of the field surveys. Other special status species, such as California Department offish and Game (CDFG) species of special concern, were noted if encountered. 1.2 Project Description The proposed project is located in the northeast portion of the City of Bakersfield in Kern County, California (Figure I). The two components of the bike path portion of the proposed project consist of a linear route extending from the future intersection of Alfred Harrell Highway and Morning Drive south to Paladino Drive (8,400 feet), then along the Paladino Drive alignment westerly to Fairfax Road (9,750 feet). The completed bike path will be 16 feet wide with a total length of approximately 18,150 feet (Figure 2). The water facility portion of the project includes construction of water pipelines, intake structure~ raw water ponds, and a treatment facility (Figure 2). The water facilities portion of the project would consist of the following: 1) intake and iow lift station at the Kern River north of the California Living Museum (CALM); 2) ponds, high lif~ station, and turnout between CALM and the existing Kern County Soccer Park; 3) Hart Memorial Park conveyance pipeline extending west from the ponds for 3,950 feet; 4) water pipeline between Alfred Harrell Highway and Paladino Drive (same routing as bike path); 5) water pipeline between the proposed bike path and water treatment plant (WTP) site; 6) WTP site on 40 acres in the southwest corner of Section 8, Township 29 South, Range 29 East, MDB. and M.; 7) water pipeline along Paladino Drive alignment to Morning Drive (same routing as bike path); 8) water pipeline south of Paladino Drive along Morning Drive for 3,500 feet; 9) WTP access road between WTP and bike path; 10) WTP access road along bike path extending north of Paladino Drive for 3,500 feet; and 11) WTP access road section along Paladino Drive alignment extending east of bike path for 1,300 feet. Northeast Baker,field Bike Path and Water Facilities 1 Biological Resource Assessment City of Bakersfield Bio Resources Consulting 1.0 INTRODUCTION 1.3 Regulatory Framework Activities associated with construction, operation, and maintenance of the proposed project have the potential to impact federal and/or state-listed species. Therefore, the project is subject to the California Endangered Species Act (CESA) and the Federal Endangered Species Act (FESA).The following paragraphs provide a brief summary of the regulatory framework provided by FESA and CESA. Federal and State Endangered Species Acts FESA protects federally-listed threatened and endangered species. Section 9 of FESA prohibits acts which result in "take" of threatened or endangered species. "Take" is defined as killing, harming, or harrassment of listed species. "Harm" has been further defined to include killing or injuring due to significant obstruction of essential behavior patterns (i.e. breeding, feeding, or sheltering) through significant habitat modification of degradation. Violation of the section can result in penalties of up to $20,000 Two sections of FESA contain provisions for allowing "take" which is incidental to otherwise lawful activities. Under Section 7, a federal agency which proposes to conduct, fund or approve an action which may result in "take" of listed species is required to consult with the U.S. Fish and Wildlife Service (USFWS). The result of this formal consultation is a Biological Opinion, which includes either a jeopardy or nonjeopardy decision issued by USFWS to the consulting federal agency. Included in the Biological Opinion is the possible issuance of authorization for "incidental take". Section 10(a) of FESA provides a method for permitting a state or private action which may result in "incidental take". Under Section 10(a), the project proponent must provide the USFWS with a Habitat Conservation Plan for the affected species, and publish notification of the application for a permit in the Federal Register. CESA provisions to permit impacts of California-listed rare, threatened, or endangered species are similar in that there is a permit process. The applicant must enter into a management agreement with the California Department offish and Game (CDFG). This management agreement specifically defines the permitted activities and how the applicant must act to protect affected species. The project area lies within the geographic area covered by an existing HCP, the Metropolitan Bakersfield Habitat Conservation Plan (MBHCP). The MBHCP was implemented in August 1994 by the City of Bakersfield and the County of Kern to allow development and similar activities to occur in exchange for habitat conservation for the affected species. Section 404 of the Clean Water Act (CWA) The U.S. Army Corps of Engineers (ACOE), under Section 404 of the Clean Water Act, regulates discharges of dredged or fill material in "waters of the United States." The term Northeast Bakersfield Bike Path and Water Facilities 4 Biological Resource Axsessment Ci .ty of Bakersfield Bio Resources Consulting 1.0 INTRODUCTION "waters" includes wetlands and non-wetland bodies of water that meet specific criteria as defined in the Code of Federal Regulations (CFR). The definition of"waters of the United States" includes "...intrastate lakes, rivers, streams (including intermittent streams)...the use, degradation or destruction of which could affect interstate or foreign commerce..." and tributaries of water defined as waters of the United States. Some intermittent washes may also qualify as waters of the United States. Areas which meet the definition of waters of the United States, or the definition of wetlands, could be under ACOE jurisdiction. At the discretion of the ACOE, impacts to these areas could require a permit, depending on the type and size of the activity within ACOE jurisdiction. California Fish and Game Code; Sections 1.600 - 1603 Any activity that will divert or obstruct the natural flow or change the bed, bank, or channel of any river, stream, or lake must provide a Streambed Alteration Notification to CDFG Additionally, Streambed Alteration Notification is required if streambed material is proposed for removal. Providing Streambed Alteration Notification to CDFG may result in a Streambed Alteration Agreement between the project applicant and CDFG. Construction activities in intermittent streams may also require a Streambed Alteration Agreement. Northeast Bakersfield Bike Path and Water Facilities 5 Biological Resource Assessment Ci~ of Bakersfield Bio Resources Consulting 2.0 ENVIRONMENTAL SETTING The information presented in this section is a summary of pertinent information regarding the climate, rivers and drainages, vegetation, and special status species of the project vicinity. 2.1 Climate The project site is located in the southern San Joaquin Valley, a broad treeless plain in the rain shadow of the Coast Ranges. The region's climate can be characterized as Mediterranean, with hot, dry summers and cool, moist winters. Summer high temperatures typically exceed 100° Fahrenheit (F), with an average of 110 days per year over 90° F. Winter temperatures in the San Joaquin Valley are mild, with an average of 16 days per year with frost (Twisselmann 1967). Rainfall varies increases from west to with the west side of the valley receiving an of east, average around 4 inches per year and the east side averaging about 6 inches per year. Winter fog, called "tule fog", sometimes forms during the months of November, December, and January, supplementing the annual precipitation. On average, approximately 90 percent of the rainfall occurs between November 1 and April 1. The region periodically experiences drought cycles, the most recent occurring during the mid and late 1980's (Twisselmann 1967). These conditions have contributed to the formation of vegetation adapted to dry conditions, and which is distinguishable from the Mojave Desert to the east due to tule fog, higher humidity, and isolation from continental climatic influences by mountain ranges (Twisselmann 1967). 2.2 Rivers and Drainages The Kern River flows along the northern portion of the project area, and is the water source for two structures associated with the project. The Kern River watershed originates on the western slopes of Mount Whitney in the southern Sierra Nevada. The watershed includes approximately 2,400 square miles draining into the San Joaquin Valley, a closed basin. Historically, the Kern River was the source of Buena Vista and Kern lakes, forming vast shallow lakes, marshlands, and sloughs in the southern San Joaquin Valley. Isabella Dam was built in 1953 approximately 40 miles upstream of Bakersfield. The dam has been used to impound water and regulate flows to the lower portion of the Kem River (Jones and Stokes 1988). In combination with agricultural diversions, the regulation of river flows has resulted in the nearly total reduction of freshwater marshes and riparian habitat associated with Kern River waters through the southern San Joaquin The of the which is the Kern River is located of Valley. portion project adjacent area to upstream agricultural diversions. Therefore, flows in this area are generally perennial. The Kern River through Bakersfield has been identified as a wildlife migratory and movement corridor for birds and larger mammals, in addition to other wildlife (Dames and Moore 1990). In addition to resident wildlife, the riparian habitats along the river are used by a wide variety of birds during spring and fall migration (Wolfe 1996). Northeast Bakers. field Bike Path and Water Facilities 6 Biological Resource Assessment Ci.tv of Bakersfield Bio Resources Consulting 2.0 ENVIRONMENTAL SETTING Aquatic wildlife of the Kern River near the project consists primarily of several common introduced and some native amphibians and fish such as Pacific tree frog (Hyla regilla), bullfrog (Bufo boreas), rainbow trout ( Oncorhynchus mykiss), smallmouth bass (Micropterus punctualatus), largemouth bass (Micropterus sabnoides), and common carp (Cyprinus carpio). Although existing survey data is minimal, native fish which are likely to occur along this portion of the Kern River include hardhead (Mylopharodon conocephalus) and Sacramento squawfish (Ptychocheilus grandis) (Maguire, pers. comm. 1998). An unnamed intermittent stream is located within the project area. This drainage originates in the Kern Bluff Oilfield and is approximately two miles long with an additional approximately one mile tributary. About one mile of the drainage is located within the project area. The drainage is primarily dry, with storm events being the only time that it may flow. Surface water during these events typically quickly dries or percolates prior to any flow reaching the Kern River. 2.3 Vegetation For purposes of this biological resource assessment, the vegetation of the project area may be adequately described utilizing the descriptions defined in Holland (1986). Where an equivalent series has been identified by Sawyer and Keeler-Wolf (1995), the series is shown in parentheses. Non-native grassland (California annual grassland series) This community is the primary vegetation of the survey area, and is distributed throughout the project area, both as a community and as an understory component to valley saltbush scrub and riparian vegetation. In the vicinity of the project site, this community is likely maintained by frequent fires. Non-native grasses dominate (bromes, foxtail, fescues, and oats), with showy annual forbs present to a varying degree depending on rainfall. Forb_- which are typically present include red-stemmed filaree (Erodium cicutarium), owl's clover (Castilleja exserta and C. attenuata), lupines (Lupinus spp.), goldfields (Lasthenia californica), fiddleneck, gilia, and several mustards. Cover may be sparse to dense, with annuals typically germinating in late fall and most species flowering in early to late spring. This community is widely distributed through California, generally below 3000 feet in elevation. Valley Saltbush Scrub (allsc0,1~ $~ries) In the project area, shrub cover in this vegetation community is typically dominated by common saltbush (Atriplexpolycarpa). Other shrub species which may be present include spiny saltbush (A. spinifera), cheesebush (Hymenoclea salsola), and pale-leaf goldenbush (Isocoma acradenia var. bracteata). The understory typically consists of winter- germinating annuals dominated by non-native grasses such as bromes (Bromus spp.), wild oats (Avena barbata and A. fatua), foxtail (Hordeum spp.), and fescues (Vulpia spp.). Native spring-flowering annuals may include bird's eye gilia (Gilia tricolor), fiddleneck Northeast Bakersfield Bike Path and Water Facilities 7 I~iologt~al Resource Assessment City of Bakersfield Bio Resources Consulting 2.0 ENVIRONMENTAL SETTING (Amsinckia menziesii var. intermedia), white layia (Layia glandulosa), and several species of phacelia (Phacelia spp.). On the project site, this community also contains shrubs which are more typically elements of Interior Coast Range saltbush scrub such as, matchweed (Gutierrezia californica) and bladderpod (Isomeris arborea). It is present just north and south of Alfred Harrell Highway, along a portion of the bike path and water pipeline routes. Riparian Vegetation Types Riparian vegetation found along the Kern River within the project area is not easily described using either the Holland (1986) or the Sawyer and Keeler-Wolfe (1995) classification systems. This is primarily due to the regulation of flows and lack of overbank flooding which was likely historically frequent. Under the Holland system, riparian areas most closely resemble an intergrading of Great Valley Cottonwood Riparian Forest and Great Valley Mixed Riparian Forest. The overstory of the river bank is dominated by Fremont cottonwood farther from the river and primarily (Populus frernontii) edge Goodding's black willow (Salix goodding~i), mulefat (Baccharis salicifolia), and quail bush (Atriplex lentiformis) closer to the river's edge. The upper bank also contains small areas of Arrowweed Scrub dominated by arrowweed (Pluchea sericea). Other prominent trees and shrubs in the riparian areas include California sycamore (Platanus racemosa) and elderberry (Sambucus mexicana). These communities are present at the intake and low lift station, north of the ponds, and along the Hart Memorial Park conveyance pipeline. The Sawyer and Keeler-Wolfe classifications do not include several potential series corresponding to the tree dominated communities. The arrowweed dominated areas would also be classified as Arrow weed series under this system. The riparian habitat adjacent to the Kern River in the project area was identified as having low habitat sensitivity by Dames and Moore (1990) based on lack of well-developed understory vegetation. 2.4 Special Status Species Conversion and development of natural vegetation found in the southern San Joaquin Valley have occurred for a variety ofurt ,~tn, agricultural, petroleum, and other land uses which have resulted in substantial population declines for several plant and wildlife taxa. These population declines have resulted the listing of several species as rare, threatened or endangered under the respective state and federal endangered species acts. The occurrence of state- and federal-listed rare, threatened, and endangered species with the potential to be affected by the proposed project were included in this biological resource assessment. In addition, species considered to have "special status" which are not formally listed but which meet the definition of "rare" or "endangered" pursuant to the California Environmental Northeast Bakersfield Bike Path and Water Facilities 8 Biological Resource Assessment Ci.ty of Bakersfield Bio Resources Consulting 2.0 ENVIRONMENTAL SETTING Quality Act should be considered. For this reason, impacts to species classified as rare and endangered by the California Native Plant Society and CDFG species of special concern are evaluated in this report. Special status wildlife and plant species with the potential to be affected by the project are shown in Tables 2.1 and 2.2, respectively. Species accounts for special status taxa are contained in Appendix A.

Biological field surveys were conducted between April and June, 1998. The proposed bike path and water pipeline routes were walked using belt transects. The centerline plus a 150 buffer on either side of the centerline was surveyed for special status plant and wildlife species. Although surveys were not conducted at an appropriate time for observation of some special status annual plants, habitat suitability for these species was evaluated during the surveys. If observed, important habitat elements for special status species were noted and mapped (i.e. elderberry shrubs for Valley elderberry longhorn beetle). In addition, plant communities were mapped. Direct observations of special status species and their "sign" (scat, tracks, tail drags, etc.) were noted if encountered during the surveys. One person-day was spent on the riparian area adjacent to the Kern River to document bird species using this area. San Joaquin kit fox were assumed to be present in the project vicinity based on past direct observation of kit fox and presence of known kit fox dens near the project site. Therefore, scent station surveys and spotlighting were not conducted for this species. Only known San Joaquin kit fox dens were mapped, including suspected pupping dens. Known dens are those burrows or artificial structures which measure between approximately 4 and 12 inches in height, which exhibit sign (scat, tracks, claw marks, prey remains) indicating past or present kit fox use, or other characteristics which, in the judgement of the biologist, are characteristic of dens which have been used by kit fox. Potential San Joaquin kit fox dens are burrows or artificial structures which meet the same size criteria as known dens, but exhibit no sign of kit fox use. Due to the large number of squirrel colonies within the survey containing burrows meeting the criteria for potential dens and the length of time before project construction is likely to commence, potential kit fox dens were not mapped. Northeast Bakersfield Bike Pa th att d Water Fa cilities 13 Biologica I Resottrce .,1 ssessm en t CiO, of Bakersfield Bio Resources Consulting 4.0 RESULTS 4.1 Wildlife A list of wildlife species observed during the surveys is included in Appendix B. Relative to other habitats, a large number of bird species were noted near the Kern River. Riparian habitats are known to support a wide diversity of species, particularly birds. No listed threatened or endangered wildlife species were directly observed during the surveys. However, other sign of site utilization by listed wildlife species was observed. 4. I. 1 Listed Wildlife Species Valley Elderberry. Longhorn Beetle (Desmocerus californicus dimorphus) No species specific surveys were conducted for valley elderberry longhorn beetle. The Kern River watershed is on the edge of this species' range, however, it is not known to currently occur in the vicinity of the project site. Several elderberry (Sambucus rnexicanus), the genus exclusively used by this species, were observed in the riparian habitat adjacent to the Kern River along the Hart Memorial Park conveyance pipeline (Figure 3). Therefore, this species may be present in the project area. Blunt-nosed leopard lizard (Gambelia sila) Species specific surveys for blunt-nosed leopard lizard were not conducted. Although suitable habitat for this species was observed along all project components, much of it was highly impacted by offroad vehicles. Most of the route consisted of very dense annual grasses such as foxtail (Hordeum leporinum), bromes (Bromus spp.), and wild oats (Arena barbata), which are generally poor habitat for this species. Direct observations by the author and discussions with other biologists familiar with the area resulted in several known locations for this species which did not appear in the CNDDB, primarily in the vicinity of the southern half of the project site. The nearest locations include observations about 1 mile west of the proposed WTP, about 1.5 miles south of Paladino Drive and .5 miles east of Morning Drive, and near the base of Ant Hill (about 0.5 miles east of the WTP). Swainson's Hawk The southern San Joaquin Valley is frequented by migrating Swainson's hawks an& infrequently, nesting pairs are observed. A nest site was used by a pair of Swainson's hawks along the Kern River west of Bakersfield in 1998 (pers. comm. William Vanherweg). Although suitable nesting sites are available along the Kern River portion of the project near the intake structure, ponds, and Hart Memorial Park conveyance pipeline, no Swainson's hawks or their nests were observed during the surveys. This species has not been historically reported to nest along the portion of the Kern River adjacent to the project area.

Neither was observed during project surveys nor have they been known to nest along this portion of the Kern River for several decades. Bald Eagle The bald eagle is an infrequent winter visitor to the lower Kern River. No bald eagles were observed. San Joaquin Antelope Squirrel Surveys were conducted under appropriate conditions to observe this species. However, San loaquin antelope squirrels were not observed during site surveys. Although suitable habitat is present, it is unlikely that this species occurs on the project site. Despite extensive surveys in the vicinity of this particular project site, no San Joaquin antelope squirrels have been observed. It is thought that they may be extirpated from this area based on the fact that no antelope squirrels have been observed north or east of Bakersfield since the 1970's (Williams 1986). San Joaquin Kit Fox Three known San Joaquin kit fox dens were observed along the bike path route on the future Paladino Drive alignment (Figure 4). One of these dens was a suspected pupping den. Two known San Joaquin kit fox dens were also observed on the proposed WTP. Potential dens were common throughout all project components, primarily within the widespread ground squirrel colonies in the area. It is likely that San Joaquin kit fox forage over the entire site. survey 4.1.2 Other Wildlife Species of Concern A burrowing owl was observed along the water pipeline along Paladino Drive (Figure 4). Several loggerhead shrikes were observed in many areas of the project site. No other unlisted species of concern were directly observed during the surveys, potential kangaroo rat were Several burrows observed in the bank of the existing bike path north of the soccer park. No diagnostic kangaroo rat sign (scat, tracks, tail drags) was observed at these burrows. However, in some places, the soil was coarse enough sand that tracks and tail drags were difficult to detect.

However, persons knowledgeable regarding the potentially occurring biological resources of the river were contacted. Although their occurrence is considered unlikely but possible (pers. comm. Dr. David Germano), the Kern River represents at least historic habitat for the southwestern pond turtle. This species was not observed during surveys. In addition, two native fish species of concern may have historically occurred along this section of the Kern River: Kern brook lamprey and hardhead. Current population status of these species along the lower Kern River is unknown. The portion of the Kern River adjacent to the intake structure, ponds, and Hart Memorial Park conveyance pipeline was "spot-checked" for Kern brook lamprey by electrofishing in approximately 1992. No lamprey were detected during this brief survey. The nearest record for the Kern brook lamprey is the Friant Kern Canal near Delano where it was first found in 1972 and described in 1975. It is but that this section of the Kern subsequently possible, not highly likely River supports a population of this species (pers. corem, Maguire 1998). 4.2 Vegetation 4.2.1 Plant Communities Plant communities described in Section 2.3, Vegetation, were mapped (Figures 3 and 4). In addition, plants observed during the surveys are listed in Appendix C. The survey area consisted primarily of non-native grassland with some areas of saltbush scrub, a wash area dominated by scale broom (Lepidospartum squamatum), and riparian vegetation along the Kern River. The riparian vegetation included woodland, savannah, and scrub areas. Riparian trees observed within the survey area included cottonwoods, willows, and sycamores. Some typical wetland plant species were observed along the water's edge; however, none of these areas were large enough to map and, over the course of the survey period the rising water level inundated much of the area where this vegetation was observed. 4.2.2 Listed Plant Species California Jewelflower California jewelflower was not observed during the surveys; however, surveys were completed too late in the season to identify this annual. The nearest presumed extant location for California jewelflower is several miles Lo northeast, off of Rancheria Road in the low Greenhorn Range foothills. Although some marginally suitable habitat was present, frequent grass fires, offroad vehicle use, oil development, and other disturbances make it unlikely that this species occurs in the project area. Northeast Bakersfield Bike Path and Water Facilities 18 Biological Resource Assessment City of Bakersfield Bio Resources Consulting 4.0 RESULTS Hoover' s wooly ~tar The survey was conducted at an appropriate time for observation of Hoover's wooly star. However, this species was not observed during the surveys. San Joaquin wooly threads An occurrence for San Joaquin wooly threads is recorded by the CNDDB approximately two miles west of the Faineax Drive terminus of the bike path. However, this population was last seen in 1905 and is very likely extirpated. No suitable habitat was observed during the surveys for the project. Although the survey was conducted too late in the year to identify this species, it is unlikely that it occurs within the project area. In addition, other surveys conducted during the appropriate period in the vicinity have not resulted in observation of this species (Rado and Mitchell 1993). Bakersfield C~tctu$ Four areas containing Bakersfield cactus were observed during the surveys (Figures 3 and 4 ). Two of these populations were within the potential construction corridor and two were observed within the buffer area. These populations represent remnant populations of this cactus, which once formed "dense almost impenetrable colonies" throughout the area (Moe and Twisselmann 1994). A total of approximately 20 cactus clumps were observed in the four areas. 4.2.3 Other Plant Species of Concern One population of cottony buckwheat was observed on the future Paladino Drive portion of the bike path route in the buffer area, near Fairfax Drive. No other plant species of concern were observed during the surveys. I ! ! Northeast Bakersfield Bike Path and Water Facilities 19 Biological Resource Assessment City of Bakersfield Bio Resources Consulting 5.O IMPACTS 5.1 Direct Impacts 5.1.1 Special Status Species Included in the MBHCP "Take" of listed threatened and/or endangered species may occur in association with all components of the project during construction, operation, and maintenance. The only listed species likely to occur in the vicinity of all project components is San Joaquin kit fox and blunt- nosed leopard lizard. One San Joaquin kit fox suspected pupping den two known dens may be impacted by construction of the bike path along Paladino Drive, near its intersection with Fairfax Drive. Potential kit fox dens may be impacted by all components of the project. Destruction or disturbance to burrows or dens could displace threatened and endangered species into adjacent areas which are either unsuitable or already occupied. Individuals could be crushed in burrows within the construction An increase in vehicle traffic and offroad in the area. access to areas project area would expose wildlife to an increased probability of vehicular mortality. Other special status species which may occur within the project area which are also covered under the MBHCP include short-nosed kangaroo rat and San Joaquin pocket mouse. Based on survey observations, short-nosed kangaroo rat may occur along the Hart Memorial Park conveyance pipeline, but is unlikely to occur on other project component areas. The San Joaquin pocket mouse may occur at all of the project component areas. One individual clump of Bakersfield cactus could be impacted by construction of the water pipeline south of the ponds. Two areas consisting of about 10 clumps of Bakersfield cactus could be impacted by construction of a portion of the bike path between Alfred Harrell Highway and Paladino Drive, the WTP access road and adjacent pipeline. Except for between the bike path and WTP site, the pipeline between Alfred Harrell Highway and Paladino Drive and the WTP access road follow the bike path alignment in this location. The remaining project components are not anticipated to impact Bakersfield cactus. No other impacts to listed plant species are anticipated, Impacts to Bakersfield cactus would be potentially significant. 5.1.2 Special Status Species not Included in the MBHCP Although not observed, Valley elderberry longhom beetle may also be present on elderberry shrubs observed within the survey area only along the Hart Memorial Park conveyance pipeline. Disturbance, including destruction of shrubs and trimming, could result in "take" of Valley elderberry longhorn beetles. Elderberfies were not present in association with other project components. Although suitable nest trees for Swainson's hawk are present near the intake structure, ponds, and along the Hart Memorial Park conveyance pipeline, the intensity of human activity in the immediate area of the project site makes it unlikely that this species would utilize these sites. However, ifa Swainson's hawk nest were to occur in the project area, project activities could Northeast Bakersfield Bike Path and Water Facilities 20 Biological Resource Assessment City of Bakersfield Bio Resources Consulting 5.0 IMPACTS disturb the individuals and possibly cause the nest to be abandoned. Suitable nesting habitat for Swainson's hawk was not observed along any portion of the bike path or any other water facilities project components. Other upland special status species which are likely to occur in the project area would be subject to the same potential direct impacts as listed species. Species which were observed during surveys or are likely to occur within the project area include Cooper's hawk, sharp-shinned hawk, burrowing owl, golden eagle, northern harrier, prairie falcon, and loggerhead shrike. Impacts to these species could occur as a result of all project components. Aquatic species could be impacted by construction and operation of the intake structure and low lift station. Species of concern which potentially occur in the Kern River which may be affected include southwestern pond turtle, Kern brook lamprey, and hardhead. Kern brook lamprey are very small and would be difficult to exclude from the intake. Additionally, it is fairly unlikely that they occur in the Kern River adjacent to the intake structure. If southwestern pond turtle and/or hardhead occur in the Kern River adjacent to the intake, individuals could be injured or killed if they entered the intake structure and lift station. Although the intake is designed for gravity flow (no suction), these species would not be precluded from entering the pipe associated with the intake. Impacts to these species would be potentially significant. Other special status species not included in the MBHCP which are unlikely to be impacted due to the small amount of suitable habitat or probable infrequent use of the site vicinity include, Kern shoulderband, LeConte's thrasher, and osprey. Of the unlisted special status plant species potentially occurring in the vicinity of the project, only cottony buckwheat was observed. The population of this species was observed in the buffer area during the survey and is unlikely to be impacted. 5.1.3 Breeding Birds All project components contain habitat elements which potentially support breeding birds, their nest and young. Riparian habitats are particularly sensitive in terms of breeding bird use. However, species such as burrowing owls use burrows in grassland habitats and several ground- nesters, such as western meadowlark, use this habitat type as well. If project construction occurs during bird nesting season (for most species, March 15 through July 31), nests, eggs, and/or young of species protected by the Migratory Bird Treaty Act could be disturbed, in violation of this statute. Northeast Bakersfield Bike Path and Water Facilities 21 Biological Resource Assessment City of Bakersfield Bio Resottrces Consulting 5.0 IMPACTS 5.1.4 Vegetation Project-related impacts which may result in disturbance to the vegetation communities found during the project surveys is shown in Table 5-1. Habitat loss through conversion to agricultural, urban, and oilfield uses is the primary reason for the listing of threatened and endangered species of the southern San Joaquin Valley. Although habitat will recover from short-term impacts, during the time of recovery, the habitat will not be able to support the same density and diversity of species which were supported prior to the disturbance. This is especially true of riparian habitat, where various plant species in the understory and overstory combine to provide complex habitat qualities. Higher quality riparian habitat is used extensively by nesting birds. In addition, snags, dying trees, and trees with cavities provide necessary nesting, roosting, and other resources for certain species. Several cottonwoods, willows, and other riparian trees were observed within the riparian vegetation along the Hart Memorial Park conveyance pipeline and at the intake structure. Although impacts to individual trees cannot be identified until construction plans are finalized~ some of these trees may be removed or trimmed during construction activities. Construction of the intake structure and turnout could additionally impact wetland habitat at the fringe of the Kern Kiver. Although wetland plant species were observed along the fringe of the river, the jurisdictional status of this area has not been determined. If any of the area near the intake structure is subject to ACOE jurisdiction, a wetland delineation would be necessary to determine whether or not wetlands meeting jurisdictional criteria are present and the extent of those wetlands. Short- and long-term impacts to vegetation would be significant. 5.1.5 Rivers and Drainages Areas within the 100-year floodplain shown on Figure 3 are potentially under the jurisdiction of the ACOE and CDFG. These areas would be impacted by construction of the intake structure, low lift station, and the Hart Memorial Park conveyance pipeline. Construction adjacent to the Kern River could increase sedimentation resulting from stormwater runoff over unvegetated surfaces. In addition, although no riparian vegetation is present, areas potentially regulated by ACOE and CDFG within the unnamed blueline stream south of Alfred Harrell Highway would be impacted by project activities. Project impacts to the blueline stream south of Alfred Harreli Highway and the area within the 100-year floodplain of the Kern River would be potentially significant. Northeast Bakersfield Bike Path and Water Facilities 22 Biological Resource Assessment City of Bakersfield Bio Resources Consulting 5.0 IMPACTS 5.1.6 Kern River Wildlife Corridor Construction of facilities associated with the Hart Memorial Park conveyance pipeline, ponds, intake and low lift station would temporarily disturb habitat and displace resident wildlife. Habitat disturbance associated with construction along the Kern River corridor would be a potentially significant impact. However, none of the project components will result in permanent facilities which would obstruct the wildlife corridor. The ponds would narrow the corridor of open space to approximately 300 feet at the closest point to the river. However, the pond location is outside of the existing riparian zone in non-native grassland, which provides relatively low habitat value and minimal cover for wildlife along this corridor (Dames and Moore 1990). Corridor restriction would primarily affect access and use by larger land mammals. The existing corridor is approximately 500 feet wide due to the presence of CALM just east of the proposed pond location and Alfred Harrell Highway is within approximately 50 feet of the river west of the project site. This impact would not be significant. !

Adjacent riparian habitats are likely to experience a greater impact from increase access than grassland or scrub habitats. Increase litter, noise, vegetation trampling, and the potential for wildlife harassment are likely to occur. Maintenance of vegetation free areas adjacent to facilities favors introduction of alien plant species into these and adjacent areas. Landscaping of the pond areas could result in introduction of invasive alien plant species to the Kern River corridor, decreasing the habitat quality for native species. These impacts would be potentially significant. 5.3 Cumulative Impacts The continuing loss of non-native grassland and saltbush scrub habitats which support special status species endemic to the southern San Joaquin Valley represents a cumulative impact of the project. The urban development which could follow the proposed project would serve to exacerbate this habitat loss. All of the lands that would be served by the proposed water facilities are included within the City of Bakersfield 2010 boundary, the limits of the MBHCP. Compensation for habitat loss through this habitat conservation plan would reduce these impacts. Cumulative impacts from development in general within the 2010 boundary have additionally been analyzed in the MBHCP (MBHCP Steering Committee 1993). Cumulative impacts potentially resulting from the project on riparian habitats include continuing fragmentation of isolation of existing remnants of this severely reduced habitat. Potential impacts to the biological resources of the riparian corridor which may result from urban development include, but are not limited to, loss of riparian vegetation, sedimentation and contamination from stormwater runoff., increased human access, noise, light, and displacement of species sensitive to human disturbance. These cumulative impacts would be considered significant. 5.4 Impact Significance The Kern County General Plan includes a Kern River Plan Element which includes the section of the Kern River adjacent to the Hart Memorial Park conveyance pipeline, ponds, intake structure and low lift station. Goals and policies from this Plan which are related to biological resource protection are summarized below: · Threatened and endangered species, and non-listed native wildlife, should be protected; Northeast Bakersfield Bike Path and Water Facilities 25 Biological Resource Assessment City of Bakersfield Bio Resources Consulting 5.0 IMPACTS · significant biological features should be identified and precluded from future development; · existing significant plant specimens and stands of riparian vegetation should be protected to the greatest extent feasible; · wildlife movement corridors should not be obstructed; and, · areas of unique or special biological resources should be identified by resource agencies and enhanced and protected (Dames and Moore 1990). Impacts to biological resources may be considered significant if a project has the potential to substantially degrade the environment, substantially reduce the habitat of a fish or wildlife species or cause a fish or wildlife population to drop below self-sustaining levels, threaten to eliminate a plant or animal community, or reduce the number or restrict the range of a rare or endangered plant or animal. Additionally, Appendix G of the California Environmental Quality Act Guidelines lists several effects which may result in a project being deemed "to have a significant effect on the environment", with the following pertaining to biological resources: · Conflict with adopted environmental plans and goals of the community where it is located; · Substantially affect an endangered, rare, or threatened species of animal or plant or the habitat of the species; · Interfere substantially with the movement of any resident or migratory fish or wildlife species; or, · Substantially diminish habitat for fish, wildlife, or plants. ,! Northeast Bakersfield Bike Path and Water Facilities 26 Biological Resource Assessment Ci~. of BakersfieM Bio Resources Consulting 6.0 PROPOSED MITIGATION 6.1 Measures to Mitigate Direct Impacts 6.1.1 Special Status Species Included in the MBHCP With the exception of the area within the 100-year floodplain of the Kern River, the proposed project area is within the plan area for the Mettropolitan Bakersfield Habitat Conservation Plan (MBHCP). Therefore, for upland species included within the MBHCP, primary mitigation would consist of participation in this program through compensation for habitat disturbance and implementation of take avoidance measures. The following is a summary of these measures: · Compensation for each acre of disturbance at the current mitigation fee; · Monitoring and excavation of each known San Joaquin kit fox den which cannot be avoided by construction activities; and · Notification of wildlife agencies of relocation opportunity prior to ground disturbance in areas where known kit fox dens or Bakersfield cactus exist. To implement measures regarding San Joaquin kit fox, a preactivity survey shall be conducted not more than 30 days prior to the onset of construction activities to determine the necessity of den excavation or Bakersfield cactus relocation. If Bakersfield cactus is relocated, a qualified biologist/botanist shall supervise the relocation activities and site selection. Suitable sites may include California Living Museum or berms of proposed ponds with appropriate soil conditions (including lack of saturation), aspect, and slope. The following measures shall be implemented to further reduce impacts to these species: · All pipes, culverts, similar structures with a diameter greater than 4 inches shall or be capped or blocked to prevent entry by San Joaquin kit fox and other wildlife. If pipe is not capped (i.e. short pipe segments stockpiled prior to use), it should be inspected for kit fox. If any kit fox are pipe, they observed within shall be allowed to escape unimpeded; ° all trenches or steep-walled excavations greater than three feet deep shall include escape ramps to allow wildlife to escape. Each excavation shall contain at least one ramp, with long trenches containing at least one ramp every 1/4 mile. Slope of ramps shall be no steeper than 1:1; · all employees, contractors, or other persons involved in the construction of the project shall attend a "tailgate" session informing them of the biological resource protection measures which will be implemented for the project. The orientation Northeast Bakersfield Bike Path and Water Facilities 27 Biological Resource Assessment Ci~. of Bakersfield Bio Resources Consulting 6.0 PROPOSED MITIGATION Shall be conducted by a qualified biologist and shall include information regarding the life history of the protected species, reasons for special status, a summary of applicable environmental law, and measures intended to reduce impacts. For any portion of the project area within the 100-year floodplain of the Kern River, a request shall be submitted to the MBHCP Implementation Trust Group to allow for compensation for habitat disturbance through the plan. The Implementation Trust Group can allow projects within the 100-year floodplain to participate in the MBHCP at their discretion. This plan covers the following listed species which have been identified as being potentially impacted by the proposed project: blunt-nosed leopard lizard, San Joaquin kit fox, and Bakersfield cactus. Based on the broad, ecosystem-based approach of the MBHCP, compensation through participation in this plan would be sufficient to mitigate for loss of habitat for other potentially occurring upland non-listed special status species potentially occupying the project area. Participation in the MBHCP would not sufficiently mitigate for impacts to the following potentially affected special status species: Valley elderberry longhorn beetle, hardhead, southwestern pond turtle, and Swainson's hawk. 6.1.2 Special Status Species not Included in the MBHCP Valley elderberry longhorn beetle, southwestern pond turtle, and Swainson's hawk are primarily riparian-associated species which were not included in the MBHCP. The following measures shall be implemented to avoid impacts to these species: · Elderberry shrubs shall not be destroyed, trimmed, or otherwise impacted to avoid the potential for "take" of Valley elderberry longhorn beetle. If elderberry shrubs cannot be avoided, USFWS shall be contacted for further guidance regarding this species; · if Swainson's hawks are observed nesting during the preactivity survey, CDFG shall be contacted for guidance. No project activities shall be conducted within a buffer area acceptable to the CDFG until young have been determined by a CDFG- approved biologist to have fledged. · if southwestern pond turtles are found during preactivity surveys or construction, they will be relocated by a USFWS and CDFG-approved biologist to appropriate habitat in the vicinity of the project site. In the unlikely event that southwestern pond turtle nests may be impacted, USFWS and CDFG shall be contacted for further guidance; · The intake structure should be designed with screening sufficient to exclude southwestern pond turtle and hardhead. Northeast Bakersfield Bike Path and Water Facilities 28 Biological Resource As*exsmenl City of Bakersfield Bio Resources Consulting I 6.0 PROPOSED MITIGATION 6.1.3 Breeding Birds Native bird and raptor nests are protected under the Migratory Bird Treaty Act. If possible, all site grading and activities which could directly impact riparian vegetation should be conducted between August 1 and March 14, during the non-breeding season for most bird species. If these activities must be conducted during the breeding season (March 15 through July 31), a biologist should survey the vegetation for bird nests prior to grading. If no active bird nests are located, grading in areas where no active nests are present could occur during breeding season. The following measure will be implemented to reduce potential impacts to native birds and raptors: · In compliance with Sections 3503 and 3503.5 of the California Fish and Game Code, if grading is to occur during the native bird and raptor nesting breeding season (March through July ), a qualified biologist 1 5 3 I shall determine the presence of any native bird and raptor nests prior to or concurrent with grading activities. In addition, CDFG will be contacted to obtain and comply with all appropriate procedures relative to grading operations in proximity to any active nests identified. Resulting mitigation measures may include restricting construction activities near native bird and raptor nesting sites during and immediately following the breeding season. 6.1.4 Vegetation Loss of vegetation associated with non-native grassland and valley saltbush scrub would be adequately mitigated through implementation of measures included in Section 6.1.1, above. However, the following measures shall be implemented to mitigate for potential impacts to riparian vegetation: · construction within 50 feet of the dripline of Fremont cottonwoods and sycamores shall be avoided, t° the maximum extent possible. Buffer zones for trees to be avoided shall be clearly marked with caution tape or similar material. If any of these species cannot be avoided, individuals over 3 inches dbh should be replaced on or adjacent to the site at a 3:1 ratio for each tree impacted. · Riparian scrub habitat disturbed as a result of project construction on the Hart Memorial Park conveyance pipeline shall be allowed to regenerate on-site. · Replacement of riparian trees and revegetation of riparian scrub habitat shall be documented in a Riparian Habitat Mitigation Plan to be submitted to CDFG and USFWS prior to issuance of a grading permit. This plan shall be prepared by a qualified revegetation specialist or biologist experienced in riparian habitat restoration. At a minimum it shall identify trees to be removed and anticipated riparian scrub habitat disturbance, monitoring plan, and success criteria. The Northeast Bakersfield Bike Path and Water Facilities 29 Biological Resource Assessment CiO' of Bakersfield Bio Resources Consulting 6.0 PROPOSED MITIGATION minimum monitoring period shall be not less than 5 years to determine replacement and revegetation success. · In areas where there is the potential for the project to result in sedimentation of the Kern River or adjacent riparian habitats, silt fencing or other suitable methods shall be employed to prevent erosion of exposed construction surfaces into these areas. 6.1.5 Rivers and drainages A formal streambed and wetlands delineation will be conducted onsite to determine the extent of impacts to areas that fall within the jurisdiction of CDFG and ACOE. Subsequent to the formal delineation, the following mitigation measure will be implemented to reduce potential impacts to jurisdiction streambeds and wetlands to a less than significant level: · Prior to the issuance of a grading permit and/or approval of plans and specifications, there will be a determination as to whether the proposed project could potentially affect jurisdictional streambeds and/or wetlands. If there is a potential to affect streambeds and wetlands, California Fish and Game Code~ Section 1601 Streambed Alteration Agreement and/or a Clean Water Act permit from ACOE will be obtained from CDFG and/or ACOE, respectively. The CDFG and ACOE typically require mitigation plans to be prepared prior to the loss of habitat within streambeds and wetlands. Mitigation may consist of habitat replacement at a ratio of 1:1 or greater for each acre lost through project implementation. 6.1.6 Kern River Wildlife Corridor Mitigation measures for impacts associated with vegetation disturbance along this corridor are addressed in Sections 6.1.4 and 6.1.5. No further mitigation measures are necessary to address the potential project impacts along the Kern River wildlife corridor. 6.2 Measures to Mitigate Indirect Impacts 6.2.1 Offsite Habitat Degradation · During construction, site boundaries shall be clearly marked with flagging, fencing, or other suitable material to prevent construction equipment and vehicles from impacting adjacent habitat areas potentially occupied by special status species. · All trash and food waste shall be disposed of in closed containers and regularly removed from the project construction site and completed bike path. Absolutely no deliberate feeding of wildlife should be allowed. Northeast Bakersfield Bike Path and Water Facilities 30 Biological Re$ource.-t.~sessmenl City of Bakersfield Bio Resources Consulting I I 6.0 PROPOSED MITIGATION I · Information kiosks shall be provided at parking areas for the bike path which contain information regarding sensitive biological resources present along the bike path and general vicinity. Prior to posting, the information presented should be I. approved by CDFG and USFWS. · If the ponds or WTP are landscaped, a landscape architect familiar with native I plant material and knowledgeable regarding invasive exotic plants shall be retained to at least review landscape plans. Among others, the following invasive exotic plants shall not be used in any project landscaping: tamarisk (all species), pampas I grass, water hyacinth, or castor bean. In addition, vegetation on the ponds shall be managed in a way such that none of the invasive exotic plants listed above is allowed to become established.

APPENDIX A Brief Descriptions of Special Status Species Known to Occur (historically and currently) in the Vicinity of the Project Site Invertebrates Desrnocerus californicus dimorphus Valley elderberry longhorn beetle The historic range for this beetle includes the entire Great Central Valley from Redding south to Bakersfield. Formerly extensive riparian forests along major drainages are thought to have supported this species on elderberry, shrubs. The species depends on elderberry for all phases of its life cycle, larvae, pupae, and adult. Adults emerge after I or 2 years and feed on the leaves and possibly the flowers of the elderberry.. Adults leave oval exit holes in the bark of elderberries after emergence. They are approximately 2 cm long at maturity. Females have dark metallic green forewings trimmings may with flame while males be colored similarly or red and black with dark green spots. Adult beetles have long, segmented antennae (BioSystems 1994). Although the Valley elderberry, longhorn beetle is currently only known from the Sacramento, American, and San Joaquin rivers and thbutaries, elderberries with riparian habitat of other river systems within this species' historic range are considered potential habitat. Helrmnthoglypta callistoderrna Kern shoulderband Little is 'known about this snail of sandbars and edges of the Kern River. The last known collection of the Kern shoulderband is from a 1939 literature citation noting a collection from dead vegetation on the river's edge. Amphibians and Reptiles Clemrnys marmorata pallida southwestern pond turtle Adult westem pond turtles are moderately large, with carapace length reaching up to 9 inches. Hatchlings are about I inch in length. Like other turtles, the flattened legs, head, and neck can be drawn into the carapace when the animal is threatened. The carapace is Iow and broad, and is generally widest in the anterior portion. The shell is smooth and lacks a keel or serrations. The hind feet are webbed to the base of the claws. Typically, the dorsal coloration ranges from dark brown to olive, with or without darker streaks. Ventral coloration ranges from cream colored to light yellowish with markings. scattered darker The southwestern pond turtle frequents streams, rivers, ponds, lakes, and marshes. Dense cover and exposed basking sites key to suitable southwestern pond turtle habitat, with deeper, slow pools being are components preferred. Although the lower Kern River and adjacent marshes and sloughs historically supported southwestern pond turtles, they are currently considered to be infrequent along this portion of the river. Northeast Bakersfield Bike Path and Water Facilities A ~1 Biological Resource Assessment Ci.ty of Bakersfield Bio Resources Consulting I Gambelia sila blunt-nosed leopard lizard The blunt-nosed leopard lizard is a relatively robust lizard with a Iarge head and blunt snout. It xvas historically distributed over the San Joaquin Valley adjacent lower foothills, plains, and vallevs. Adult total length may reach up to 13 inches. Coloration consists of a light grayish, tan, or brown background with a conspicuous pattem of dark overlaying spots and/or pale crossbars. During the spring courtship season both sexes may develop reddish markings on the sides, tail, and ventral surfaces. Juveniles usually show a similar, but more yellowish pattern. Blunt-nosed leopard lizards are active during the day, primarily between the months of April and October. Peak daily activity usually occurs when air temperatures are between 75 and 95 degrees Fahrenheit. Animals overwinter underground in rodent burrows. Food consists primarily of insects such as grasshoppers, although smaller lizards may also be consumed. Leopard lizards occur on sparsely vegetated plains, lower canyon slopes, on valley floors, and in washes. Associated vegetation may include a variety of grasses, saltbush, golden bush~ iodine bush, and seepweed. Phrynosoma coronatum California homed lizard The California homed lizard is a fiat bodied lizard that is up to 6 inches in length. It has a large croxm of spines on the posterior portion of its head. The cranial spines of the California homed lizard tend to be similar in size, whereas the central two spines tend to be longer in the other subspecies. There are large dark spots on the side of its neck and there are two rows of pointed scales at the fringe of its trunk. Coloration is reddish, brown, yellow, or gray with dark blotches on the back; coloration is variable and is possibly dependent upon soil coloration. This lizard lays a clutch of 6 to 12 eggs in May or June, and hatchlings emerge in July or September. Their main food source is ants. This lizard is diurnal and will inflate with air when frightened to avoid predation. Other defensive strategies include threatening would-be enemies with an open mouth and hissing noises, tilting its head to expose the cranial spines, biting, and spraying blood from the comer of its eyes. The California homed lizard occurs along the coast north of San Francisco Bay to Los Angeles, and inland into the Sacramento and San Joaquin valleys. It inhabits open areas of sandy soil with low sparse vegetation. Birds Accipiter cooperi ° Cooper's hawk This medium-sized hawk (length = 14-20 inches: wing span = 29-37 inches) is mostly brown above, with the male being more bluish above and more heavily marked (barred) below. The tail is strongly barred on the underside. Juveniles are lighter below, with f'me streaks in the chest area. As in most raptors, the female is substantially larger than the male (app 1/4 to 1/3 larger). The long tail and short, rounded wings are characteristic of the genus Accipiter. Also diagnostic of the genus is the flight profile, which consists of a series of strong, rapid beats followed by a glide. Cooper's hawks can be confused with the similar but smaller sharp-shinned hawk, as these two species have similar coloration and body proportions. However, the larger size, proportionately larger head, more distinaive black cap, and longer, more rounded tail distinguishes the Cooper's hawk. Northeast Bakersfield Bike Path and Water Facilities ,4-2 Biological Resource Assessment City of Bakersfield Bio Resources Consulting Acctpiter striatus Sharp-shinned hawk Sharp-shinned hawks are similar in appearance to Cooper's hawks, but smaller. Their diet consists primarily of birds. In the project area, riparian woodlands provide suitable habitat for this species. Aquila chrysaetos Golden eagle golden eagle a large, brown raptor (length = inches; wing span inches) The is 30-40 80-88 that. in the western states, occurs primarily in open, mountainous areas, foothills, canyons, and plains. Large size and flat-winged soaring distinguish the golden eagle from large hawks. Immature golden eagles may be distinguished from immature bald eagles by their thinner bills and relatively smaller heads. In flight, as viewed from below, immature golden eagles show more clearly defined white patches at the base of the primaries and also a distinctive white tail with a dark terminal band. The golden eagle is a circumpolar species that occurs over much of the United States and southem Canada. In the western United States, it is a year-round resident. Nesting occurs in trees and on cliff faces. Their diet consists primarily of mammals (mostly iagomorphs and ground squirrels), birds, and snakes. Athene cunicularia Burrowing owl Adult burrowing owls are sandy colored over the head, back, and wings, with barring on the breast and belly. Juveniles are smaller, and buffy below. Burrowing owls are medium-sized (body length averages 9.5 inches), yellow-eyed owls with disproportionately long legs. The tail is very short: the head is rounded and lacks ear tufts. The long, exposed lower legs, and the characteristic "bowing" behavior that the bird displays when approached or otherwise disturbed, quickly distinguish this owl from all other small owls. During the nesting season, the burrowing owl often perches on a low post or at the entrance to a burrow. Calls are often synchronized with bowing behavior. When approached or flushed, both sexes commonly give a sharp "chatter" call. Resident burrowing owls begin pair formation as early as December, and migratory birds begin upon their arrival in the breeding area, usually in March and April. Six to eleven eggs are laid during late March to early May. lasts about four weeks. Nests are generally located bare, ground Incubation in level in abandoned mammal burrows. Burrowing owls inhabit dry, grasslands, rolling hills, desert floors, prairies, agricultural land. open savannas, and other areas of open, bare ground. These owls will also inhabit open areas near human habitation, such as airports, golf courses, shoulders of roads, railroad embankments, and the banks of irrigation ditches and reservoirs. Buteo swainsoni Swainson's hawk Swainson's hawk is a medium-sized (to 18 inches), dark breasted hawk of grasslands and open woodlands in California, preferring riparian trees for nesting. Certain types of agricultural fields adjacent to riparian areas also provide foraging habitat for nesting pairs. Diet includes rabbits, lizards, snakes, frogs, and occasionally insects. Northeast Bakersfield Bike Path and IVater Facilities A-3 Biological Resource Assessment CiO' of Bakersfield Bio Resources Consulting Reduction of riparian habitat in California has reduced the nesting range of this species to primarily the Sacramento Valley, with occasional nesting to the south through Kern County. Fairly large numbers of these hawks migrate through the Central and San Joaquin valleys to their wintering grounds in South America. Circus cyaneus Northern hamer The northern hamer is a medium-sized (length = 17-24 inches; wing span = 38-48 inches), relatively slender hawk that is most easily recognized by its conspicuous white romp. Wings are comparatively long, as in falcons, but are more rounded. This raptor is unusual in that sexual dichromatism is pronounced: females are mostly brown above and white with brown streaks below, whereas males are generally grayish above, white below, and the wing tips are black. Also diagnostic is the erratic flight of leisurely wing beats and swift glides, usually low to the groun& and with wing tips up-tamed. Hamers also often perch close to the ground. Northern harriers range throughout North America, and in California they are usually year-round residents (some southern California birds may be over-winter visitors). Formerly known as the marsh hawk, these birds primarily inhabit marshes~ fields, and prairies. Diet consists primarily of small rodents, though frogs, reptiles. and insects are also taken (Ehrlich et al 1988). Empidonax trailii WillOw flycatcher This flycatcher is vepy similar in appearance to other flycatchers found in Califomia. It is olive-brown above with a pale yellow belly, white wing bars, and no eye ring. This species nests in shrubby habitat, frequently' willows, near streams, ponds, and wet meadows. In 1986, it was estimated that there were as few as 150 nesting pairs in California. Reduction of riparian habitat through clearing and channelization of streams and rivers and nest parasitism are the major threats to this species. Cattle grazing in remote areas may promote cowbird populations, the main parasite on willow flycatchers (BioSystems 1994) Falco mexicanus Prairie falcon The prairie falcon is a medium-sized falcon (length = 15 -20 inches; wing span - 35-43 inches) of mostly brown coloration. The underside is creamy white and heavily spotted with brown. Long, pointed wings and long tail distinguish this species from other, non-falcon raptors. Prairie falcons are very. powerful flyers, and are among the fastest of birds. Among similar species, the pereghne falcon has a darker dorsal surface and more black on the face. In flight the Prairie Falcon is easily identified by the presence of dark patches in the axillary region (= wingpits). Prairie falcons occur in arid portions of western North America. Northern indMduals (e.g., from e,~qtem Washington and southern Canada) may winter in Mexico, whereas in Califomia the species is a ye-r-round resident. This is a bird of generally dry, open country such as plains, prairies, and deserts, and can be relatively common in canyon country, where it is attracted to the nesting sites afforded by cliffs and rock outcrops. The diet of prairie falcons consists primarily of small mammals and birds, although a variety or other prey species may also be taken (e.g, lizards, insects) (Ehrlich et al 1988). Northeast Bakersfield Bike Path and Water Facilities A-4 Biological Resource ,4ssessment City of Bakersfield Bio Resources Consulting Haliaeetus leucocephalus Bald eagle This very large, easily recognizable raptor (adults) breeds in northern California, from near Lake Tahoe north through the Cascade Range and west to the Coast Range. Juveniles can be confused with golden eagles, although upon close inspection these two species can be differentiated. Bald eagles winter through much of the state, the exception being the Mojave Desert and high areas of the Sierra Nevada. With a diet of primarily fish, bald eagles need reservoirs, lakes, and rivers for foraging. The species is infrequently sighted dtmng winter along the Kern River, and is unlikely to roost here. Lanius ludovicianus Loggerhead shrike The loggerhead shrike is a robin-sized bird (length = 9 inches) with a raptor-like, hooked bill. Dorsal coloration is bluish-gray, and ventral coloration is whitish, with very faint barring. Juveniles are more brownish. Most distinctive is the black eye mask, and in flight, the white wing patches on the contrasting dark wings. Distinguished from the northern mockingbird, which it resembles in flight, by darker wing and smaller white wing patches. The mockingbird also lacks conspicuous eye patch and hooked bill, and has slower xving beats. This'shrike occurs over most of the U.S., Mexico, and central Canada. In California, the shrike occurs as a resident over most of the state~ being absent from high mountain regions. Habitat consists of open areas, such as savannas and deserts, where bushes, small trees, or other perch sites are available. Lacking talons, the shrike impales its prey to facilitate feeding, or to store it for future consumption. Diet includes a vafietx, of insects and spiders, small reptiles, rodents, and small birds (Ehrlich et al 1988). Pandion haliaetus Osprey This raptor is distinctive in coloration, white with conspicuous black markings, including a black patch on each "wrist" and black eye stripe. It is considered uncommon, occumng along coasts lakes and rivers where it forages for fish. Other prey items include rodents, birds, and crustaceans. It is occasionally observed along the California Aqueduct, Kern River, and other water bodies around Bakersfield. However, it is not 'known to nest along the lower Kern River. Toxostoma lecontei LeConte's thrasher LeConte's thrasher is the palest in color of all the thrashers. It has sandy gray plumage with a somewhat dark tail. The bill and eye are dark and '; has a yellowish tinge on the romp. Its bill is down-turned and it is often observed perching atop saltbush sm-ubs, other tall shrubs, and fence posts. LeConte's thrashers inhabit add, sparsely vegetated deserts of southern Nevada, western Arizona, extreme northwestern Mexico, and southeastem California. It is also found in the add SanJoaquin Valley. It runs with surprising speed across open desert or along washes. It is uncommon throughout most of its range and is rare in the San Joaquin Valley,. Northeast Bakersfield Bike Path and Water Facilities A-5 Biological Resource Assessment City of Bakersfield Bio Resources Consult#tg Vireo bellii pusillus Least Bell's vireo small, gray and white songbird, once bred through much of Califorma, using willow, wild rose. and other This thickets along riparian areas for nesting. It has not been recorded nesting along the lower Kern River in several decades. Mammals Ammospermophilus nelsoni San Joaquin antelope squirrel The San Joaquin antelope squirrel is a small, yellow-brown squirrel with two distinguishing white stripes along dorsal side of the body. In contrast to other listed mammals in their range, these squirrels are diurnal and are active year-round. Their young are apparently bom in March and appear above ground in early April (Kakiba-Russell et al. 1991). San Joaquin antelope squirrels are most often found in grasslands or open shrublands. Associated shrubs include saltbush, ephedra, bladder pod (Isomeris arborea), goldenbush (Isocoma acradenius= Haplopappus a.), snakeweed (Gutierrezia bracteata), and others. San Joaquin antelope squirrels are omnivorous, with a diet consisting primarily of grass and herb seeds and insects (CDFG 1989). It appears that San Joaquin antelope squirrels rarely occupy burrows they have dug; instead, they'tend to use burrows dug by kangaroo rats. In grassy, shrubless areas, Hams and Steams (1990) found San Joaquin antelope squirrels only in areas with high kangaroo rat densities. The San Joaquin antelope squirrel originally occurred on the western side of the San Joaquin Valley from southern Merced County south to Kern County, the Carrizo Plain in San Luis Obispo County, and the Cuyama Valley in San Luis Obispo and Santa Barbara counties (CDFG 1980). Prior to cultivation of the San Joaquin Valley, the San Joaquin antelope squirrel occupied approximately 3,456,000 acres (Williams 1980). More than 80 percent of this estimated original geographic range is now under cultivation, with this species having been nearly extirpated on the eastern side of the San Joaquin Valley (Williams 1980). No large tracts of prime habitat remain, and only about 15 percent of the remaining habitat is considered to be good to fair in quality. San Joaquin antelope squirrels now occur only in the southwestern portion of the San Joaquin Valley and in adjacent valleys to the west (Williams 1980). Dipodotnys nitratides brevinasus Short-nosed kangaroo rat The short-nosed kangaroo rat is a small species of the genus Dipodomys, measuring up to 9 inches in total length. It is one of three recognized subspecies of the San Joaquin kangaroo rat (Dipodomys mtrato~des). Overall appearance is that of a compact rodent, with a flattened head, small ears, short neck, and cylindrical body. The hind legs are elongated and serve as the principal means of locomotion. The long tufted tail. comprising about one-half of the total length of the animal, provides balance. Coloration is brownish above changing to whitish ventrally. The presence of four toes on the feet of this taxon helps to distinguish it from other sympatric kangaroo rat species (Uptain 1989). Short-nosed kangaroo rats excavate shallow burrows from which animals emerge at night to forage for seeds. Often, all or a significant portion of the nightly harvest is cached for later use. When foraging, kangaroo rats hold seeds in fur-lined pouches on the sides of the mouth. Little information is available on the population densities of short-nosed kangaroo rats. Northeast Bakersfield Bike Path and Water Facilities A-6 Biological Resource .qssessment Ci.ty of Bakersfield Bio Resources Consulting Short-nosed kangaroo rats are generally found on flat and gently sloping terrain and on hill tops in scrub vegetation (primarily saltbush). They are found on friable, sometimes alkaline soils. Light to moderate grazing by livestock probably enhances habitat for short-nosed kangaroo rats (Williams 1986). Short-nosed kangaroo rats are found on the westem side of the San Joaquin Valley, from near Los Banos. Merced County, southward west of the San Joaquin River in a line approximately coincident with the Kettleman Hills, Lost Hills, and Elk Hills of the southem end of the Valley. They also occur in the Panoche Valley, San Benito County., the Sunflower Valley, Kings County, the Antelope Plain in Kern Count3.'. the Carrizo Plain in San Luis Obispo County, the Cuyama Valley in San Luis Obispo and Santa Barbara counties, and at the of the floor around the southern end of the San Vallev from the edge valley Joaquin vicimty of Maricopa on the west, to east of Bakersfield on the east (Hall 1981, Williams 1985, and unpubl data. in Williams 1986). Taxidea taxus American badger American badgers are low, squat animals with conspicuous silver-tipped pelage dorsally and a short. black-tipped tail. The most striking visual feature of this species is its striped face, consisting of a median white stripe proceeding from the tip of its nose to the back of its head. This stripe is flanked by alternating white and dark stripes giving way to bright, white-outlined ears. The badger's wide flattened body is suppOrted by short but powerful legs. The front feet are fitted with noticeably long claws that are especially well-suited for digging out the burrows of the rodents on which it feeds. Historically, badgers are thought to have been fairly widespread in the open grassland habitats of the lower San Joaquin Valley. Their modem San Joaquin Valley distribution is essentially restricted to the limited, often isolated and remote tracts of native grassland and shrubland habitats. Cultivated lands have been reported to provide little usable habitat for this species, and badgers are believed to be declining throughout Califomia (Williams 1986). Badgers are solitary animals. They usually forage for burrowing prey such as gophers, ground squirrels. marmots, and kangaroo rats, although they are known to take a variety of nesting mammals, reptiles, and birds. Vulpes macrotis mutica San Joaquin kit fox The San Joaquin kit fox is one of the eight recognized subspecies kit fox. It resembles a small lanky.' dog in appearance, with disproportionately large ears containing an abundance of large, white inner guard hairs. The San Joaquin kit fox is the largest subspecies of kit fox, with adults weighing 4.5 to 5 pounds (2-2.3 kg). Total length is about 32 inches, including up to a 12-inch black-tipped tail. Coloration ranges from light buff to grayish along the back and tail, gray, mst, or yellowish along the sides, and white on the belly (O'Farrell 1983). San Joaquin kit foxes are generally nocturnal and are opportumstic carnivores. They feed on rodents. lagomorphs, birds, reptiles and insects, as well as on carrion such as road kills. Studies indicate that the primmy food items may vaxy geographically and seasonally (Kakiba-Russell et al. 1991). Dens are typically excavated in loose soil (O'Farrell 1983), but also occur in harder clay soils in the northern portion of their range. Dens are not found in saturated soils or in areas subjected to periodic flooding (Kakiba-Russell et al. 1991). Individual animals may utilize from 3 to 24 separate dens (Morrell 1972). Northeast Bakersfield Bike Path and Water Facilities A- 7 Biological Resource .dssessment City of Bakersfield Bio Resources Consulting I Number of den entrances may range from I to 36 (O'Farrell 1983), and may extend into several tunnels and chambers reaching depths of up to 10 feet (O'Farrell 1987). Most dens are vacant at any given time. During times when dens are unoccupied kit fox, they may be occupied by other burrowing animals such as badger. ground squirrels, skunks, and burrowing owls (Kakiba-Russell et al. 1991). Although occupied dens may show freshly excavated soil, scats, and prey remains (O'Farrell 1987), sign may also be inconspicuous or absent (Hall 1983). Typical den entrances are characteristically higher than wide, and are small enough to prevent access by large carnivores such as coyotes. Den entrance hole dimensions are generally about 8 to 10 inches in height and less than 8 inches in width (O'Farrell 1987), but may be as small as 4 inches in width. Burrows of other animals, particularly California ground squirrels (Spermophilus beecheyi), are opportunistically enlarged and utilized as den sites by San Joaquin kit foxes (Balestreri 1981). Most dens are found in areas with slope angles of less than 40 degrees, and natal and pupping dens are found more frequently on gentle slopes or in flat terrain. Man-made structures such as culverts and pipes may also be used as dens (O'Farrell 1983). Individual San Joaqum kit foxes have an average home range of I to 2 square miles (Knapp 1978; Morrell 1972). Courtship and mating occur in December and January. Pups are typically born in February, and March. and begin to disperse at around five months of age (Morrell 1972; O'Farrell 1983). About 75% percent of kit fox pups die before the age of eight months (O'Farrell 1984). San Joaquin kit foxes occur in Valley Saltbush Scrub, Valley Sink Scrub, Interior Coast Range Saltbush Scrub, Upper Sonoran Sub-shrub Scrub, Non-native Grassland, and Valley Sacaton Grassland. In general, kit fox are not found in densely wooded areas, wetland areas, or areas subject to frequent periodic flooding. Habitats altered by agricultural and urban developments are unsuitable for long-term kit fox inhabitance (Kakiba-Russell et al. 1991). The San Joaquin kit fox was historically distributed over a large portion of central California. extending roughly fi.om southeastern Contra Costa County south along the eastem flanks of the Interior Coast Range to the southern San Joaquin Valley, including major portions of western Kern County and Tulare Count3.'. San Joaquin kit fox were also distributed through adjacent valleys, foothills, and plains, including portions of San Luis Obispo County, Monterey County, and the Santa Clara Valley on the western side of the Interior Coast Range (Morrell 1975). Habitat conversion for agricultural and a variety of urban uses has been the principal cause of kit fox population declines, and the reason for both state and federal listing of this species. O'Farrell (1983) estimated that approximately 42 percent of suitable kit fox habitat was lost as a result of such developments. Since that estimate was made, substantial additional habitat loss has occurred. Mortality of kit foxes has been documented fi'om attacks by coyotes, road kills, conversion of habitat, shooting, drowning, entombment. pneumonia, and starvation (Morrell 1975; Knapp 1978~ O'Farrell et al. 1986~ Berry et al. 1987). Additionally, the use of certain rodenticides has resulted in secondary, mortality, since kit foxes are vulnerable to poisoning through consumption of poisoned rodents (USFWS 1985b). Plants Caulanthus californicus California jewelflower The Califorma jewelflower is an annual reaching a height of 6 to 15 inches. Foliage is gray-green, with heart-shaped clasping stem leaves and wavy margined strap-shaped basal leaves. Unopened flowers appear deep maroon in color. Open flowers are white to greenish-yellow. Suitable habitat for this species is Northeast Bakersfield Bike Path and Water Facilities A-8 Biological Resource .4ssessmenl City of Bakersfield Bio Resources Consulti. g I I non-alkaline to slightly alkaline sandy loam soils of relatively undisturbed grassland communities below an elevation of 3,000 feet. I Historically, the range of the species included the upper San Joaquin and adjacent valleys from Coalinga in the northwest to the Cuyama Valley in the southwest. Of 55 historical locations, approximately twenty extant populations remain (Skinner and Pavlik 1994). Recently, extant populations have been found on the Camzo I Plain in San Luis Obispo County, and in the Kreyenhagen Hills of Fresno County. attempt An has been made to establish an artificial population at the Paine Wildflower Preserve, Kern County. I Cirsium crassicaule Slough thistle I This biennial species, which to as an annual, is distinguished from the weedy Cirsium species appears grow by the presence of pinnate spines on the phyllaries. The slough thistle is a tall robust annual that ranges from 3 to 6 feet in height. The lower stem is typically unbranched while the upper portion is commonly much Ibranched, supporting several paniculately disposed heads. Herbage is prominently hoary-tomentose to sometimes glabrescent on the upper surfaces. Individual leaves are lanceolate in overall shape with sinuate-pinnatifid margins. Individual lobes are often spine-tipped. Flowers are whitish to pinkish. I Slough thistle is found in low-lying, seasonally to permanently wet habitats on the valley floor. The population locations in Kern and Kings counties indicate that this plant can tolerate disturbed habitats. The I northern populations of this species (in San Joaquin County) tend to be disjunct, which suggests possible dissemination by water or equipment. I Delphinium gypsophilum ssp. gypsophilum Gypsum-loving larkspur i Gypsum-loving larkspur is a perennial in the buttercup family which reaches a height of up to 4 % feet. It has a white, inconspicuous flower within generally white sepals along the flowering raceme. i As its name implies, gypsum-loving larkspur frequently occurs on gypsum-rich soils in chenopod scrub and grassland habitats. In favorable years, it occurs on north-facing slopes with other soil types as well. Eriastrum hooveri Hoover's wooly star Hoover's wooly star is a small annual species that reaches a height to 6 inches. Stems typically support erect branches. Leaves are entire and linear, three-cleft with two lateral lobes. The small and inconspicuous flowers are organized into small heads. Corollas range in color from pale bluish to white or cream yellow. Capsules are oblong-ellipsoid with two to four seeds each. Flower usually appear in mid-to late spring (April to May). The habitat for Hoover's wooly star is valley grassland with scattered saltbush (Atriplex polycarpa or A. spinifera). The plants are often found in openings in Atriplex Scrub where cryptogamic crusts have developed on the soil surface. Associated species include red brome, annual fescue, and goldfields (Lasthenia californica).This small, ephemeral, annual species was once fairly widespread on the crusty alkaline soils of the San Joaquin Valley. Much of its native habitat has been converted to agriculture. Hoover's wooly star is known to occur from Fresno County and Kem County (Bakersfield area and west and northwest of Bakersfield). It is known from the Carrizo Plain (San Luis Obispo County) and the Cuyama Valley Santa Barbara County). The species has subsequently been found at many sites bordering the Elk Hills in Kern County (R. Lewis, pers. comm 1996) and is in the process of being downlisted. Northeast Bakersfield Bike Path and Water Facilities A-9 Biological Resource Assessment CiO' of Bakersfield ' Bio Resources Consulting Eriogonum gossyptnurn Cottony buckwheat Cottony buckwheat is a small annual buckwheat with wooly, gray-green leaves and a conspicuously cottony inflorescence. The flower is white to rose and glandular. The species grows on exposed clay hills, typically south-facing. Its general distribution includes the southwestern San Joaquin Valley and low foothills of the Greenhorn Range. Lernbert~a congdonii San Joaquin wooly threads San Joaquin wooly-threads is a small, inconspicuous annual which may be 1 to 10 inches in height at maturity. Stems are multiple, decumbent and often somewhat succulent. Leaves and stems are typically loosely floccose to woolly-haired. Leaves are 1.5 inches long by about 0.25 inch wide with wavy. margins. Individual flowers are arranged in heads that are clustered towards the ends of branches. Each head has four to seven phyllaries that are commonly blacktipped. Tiny yellow ray and disk flowers appear in late February.' or March. Ray flowers and their akenes are clearly distinguished from those of the disk. San Joaquin wooly-threads are found in valley grassland habitat types with silty sand or sandy loam soils at elevations ranging from 400 feet to 1,200 feet. Valley saltbush is often the dominant shrub in these habitat types. The preferred microhabitat for this species consists of areas with reduced annual grass competition. It is generally not found where annual grasses are extremely dense and tall (Taylor 1987). This species is somewhat prostrate, allowing it to persist under grazing pressure. Known extant populations in Kern Count, occur along the Kern River near I-5, near Lost Hills, and on the Belridge Plain. This species was once fairly common in the San Joaquin Valley. Jepson (1923) described it as being much more common during years of high spring rainfall, an observation that is consistent with other reports. Various land conversion activities have eliminated most of its habitat, which is why it was listed by the USFWS as an endangered species. Opunt~a basilaris var. treleasei Bakersfield cactus cactus is a beavertail-type cactus with bright, magenta-pink flowers. It generally flowers between Bakersfield April and May. The pads differ from the common beavertail cactus in that Bakersfield cactus has spines. Spine length is highly variable through the range of this cactus. Bakersfield cactus occurs primarily on sandy soils of alluvial plains, washes, and ridges, in grassland and saltbush scrub vegetation. Although it was once common from just north of Bakersfield south along the western flank of the foothills to the vicinity of Wheeler Ridge, much of the cactus has been eliminated through urbanization and disking of grazing lands.

The project is located south of the Kern River and Alfred Harrel Highway, northeast of Bakersfield, Kern County, California. The purpose of the archaeological assessment was to satisfy requirements of the California Environmental Quality Act (CEQA) and the National Environmental Protection Act (NEPA) regarding identification and protection of cultural resources. A historic mine shaft, cement footings, and a large foundation were located along the bike path route south 'of Alfred Harrel Highway. Further research into the age and function of these features is recommended. No other historic sites or features were located. No prehistoric sites were found. No further archaeological work is recommended for the remainder of the project. ii TG&S Oultural Resource Assessment 98-07t City of Bakersfield INTRODUCTION At the request of Marc Gauthier, City of Bakersfield, a cultural resources assessment was conducted by Three Girls and A Shovel, 2820 Alta Vista Drive, Bakersfield, California, on a four mile alignment proposed for a bike path and on a 40 acre parcel proposed for a water facility. The project also includes an intake structure located at the Kern River, three ponds and a 36 inch water pipe located just south of the Kern River, and a 32 inch water pipe to be installed under the bike path. The purpose of this assessment was to satisfy requirements of the California Environmental Quality Act (CEQA) and the National Environmental Protection Act (NEPA) for the identification and protection of cultural resources. PROJECT LOCATION The project area is located northeast of Bakersfield, south of the Kern River and Alfred Harrel Highway. The bike path follows the Morning Drive and Palidino Road alignments from Alfred Harrel Highway to Fairfax Road. Specifically, the bike path route is located in Sections 5, 6, 7, and 18 of T. 29 S., R. 29 E., MDBM and Section 12 of T. 29 S., R. 28 E., MDBM. The intake structure and ponds are located in the NW 1/4 of Section 5, T. 29 S., R. 29 E., MDBM. The 36 inch water pipe route is located in Sections 5 and 6, T. 29 S, R. 29 E. The 40 acres for the water consists of the SW 1/4 of the NW 1/4 of facility Section 8, T. 29 S., R. 29 E., MDBM, as shown on the Oil Center 7.5' series USGS topographic map, 1992 (Figure 1). The elevation ranges from approximately 300 to 800 feet AMSL. RECORDS SEARCH A records search (Appendix I) was conducted at the Southern San Joaquin Valley Information Center. The records search indicated that the northern end of the bike path, the intake structure, the 36 inch water line route, and the pond areas had been included in a previous survey conducted for the soccer fields located between Alfred Harrel Highway and the Kern River (Uli 1984). Most of the Morning Drive alignment had previously been surveyed for the City of Bakersfield (Parr 1992). Most of the Palidino Road alignment had been surveyed during the Mojave Pipeline Evaluation (McGuire 1990) and for a sewer line (Valdez 1993). The 40 acres for the water facility had not been surveyed. No archaeological sites are recorded on the project, however, there is one recorded prehistoric site within 1/8 mile of the Morning Drive alignment.

ENVIRONMENTAL SETTING PREHISTORIC A recounting of the prehistoric environment of California and the San Joaquin Valley is presented in Michael J. Moratto's "California Archaeology" (1984). The following is excerpted and paraphrased from that source. The pre-contact Native Americans were completely reliant upon their natural resources. They had extensive knowledge about habitats and animals, plants, climate, rocks, and minerals. They knew how to place villages to maximize the environmental surroundings. Their cultures were strongly influenced by natural conditions and it is necessary to understand California's environmental setting to understand the pre-historic inhabitants and interpret the later archaeological record. covers approximately 157,207 square California miles and includes many geomorphic provinces. With such a large area, including a long coast line, mountains, and deserts, there is great variety and contrast in the state's physiography, geology, climate, flora, and fauna. Of special concern here is the Great Central Valley, consisting of the Sacramento Valley, the Delta, and the San Joaquin Valley. The floor of the valley is 750 km long and 30-80 km wide and is enclosed by the Siskiyou, Sierra Nevada, Tehachapi, and Coast Mountain ranges. It is underlain, mainly, by Sierran stream sediments up to 17 km deep. Elevation ranges from sea level to 100 m AMSL, broken only by the 600 m high Sutter Buttes. The Sacramento and San Joaquin River systems drain the valley and merge into the channels and marshes of the Sacramento-San Joaquin Delta. The waters later pass through a gap in the Coast Range and empty into San Pablo Bay. Over the centuries the valley experienced many dramatic environmental changes, including: faunal extinctions and replacement at the end of the Pleistocene, the emergence of wetlands, flooding, massive siltation, cyclical appearance and evaporation of shallow lakes, and biogeographic shifts in response to climatic fluctuations. In ancient times lakes, marshes, and sloughs covered more than 5,000 square km in the San Joaquin Valley alone. The largest lake, Tulare, occupied a structural basin created by down warping. Additionally, Tulare and Buena Vista Lakes were partially contained by alluvial fans reaching into the valley from the King's River and Los Gatos Creek. These coalesced into TG&S ~l~ral Res~rce Assessment 98-07t Ci~ of Bakersfield 4 a ridge and lands to the south were so arid that runoff was often not able to maintain a discharge through the alluvium. This natural dam thus contributed to the impoundment of Tulare Lake and its swampy basin. A similar projection from the Kern River fan westward to the McKittrick Hills formed a second dam behind which lie Kern and Buena Vista Lakes. At flood levels the Buena Vista and Tulare Lakes spilled into a single basin and with the waters of the Kern, Kaweah, and King's Rivers, flowed into the San Joaquin River system. The lakes are now mostly dry due to historic drainage projects. The Central Valley was attractive to the early inhabitants. The climate was locally varied, but generally pleasant. Precipitation was also variable and in the southern San Joaquin Valley, where it was scant, the water was supplemented by the snow melt from the mountains. The Central Valley's plains and wetlands had abundant game and vegetal foods. The bottom lands produced lush swamp vegetation valued for food, fiber, and building materials. Riparian woodlands grew along the watercourses. The waterways also provided the habitats for river mussels and many species of fish. Steatite and asphaltum occurred in the southern part of the valley and salt deposits were found in the north. With so many abundances, resources that were lacking, such as obsidian, were easily obtainable through trade with outside areas. With such an abundance of resources and comfortable living conditions, the eighteenth century aboriginal population was 105,000, with 53,000 people in the Sacramento Valley and 52,000 in the San Joaquin. During the long prehistory of the Central Valley there have been diverse and changing environments, along with many population movements, waves of cultural influences from neighboring groups, and a complex interplay between local and regional cultural forces. The oldest evidence for occupation of the valley comes from Tracy, Tulare, and Buena Vista Lakes and dates to about 11,500-7,500 years ago. Since the floor of the valley is covered with a thick layer of alluvium, it is likely that most of the earliest habitation evidence lies buried beneath it. This would account for the modest antiquity of artifacts, especially in the valley lowlands of the San Joaquin and Sacramento River dra'_nages. In these areas 10 m of sediments have accumulated just during the past 5,000-6,000 years. ! TG&S Cultural Resource Assessment 98-07, City of Bakersfield 5 ETHNOGRAPHY SOUTHERN VALLEY YOKUTS The Yokuts have been broken into three geographical divisions, the Northern, Foothill, and Southern Valley Yokuts. The project area lies within the territory of the Southern Valley Yokuts. The following information is excerpted from "Southern Valley Yokuts" by William J. Wallace (1978). The territory of the Southern Valley Yokuts included Tulare, Buena Vista, and Kern Lakes, their connecting sloughs, and the lower portion of the Kings, Kaweah, Tule, and Kern Rivers. The area consisted of extensive swamps and marshlands which provided an enormous variety and abundance of wildlife and aquatic flora. The southern San Joaquin Valley only received 5-10 inches of rain annually and was dependent upon the additional water being brought in from the melting snows of the Sierra Nevadas. As the Yokuts adapted to this abundance of subsistence resources they developed a culture of comparatively greater material wealth and tended to live in large, more permanent settlements. It is estimated that this way of life lasted approximately 2,000 years. At the beginning of the historic period 15 different Yokuts groups were identified in the area. Adapting to their environment, the southern Valley Yokuts developed a mixed economy subsistence pattern. It emphasized fishing, hunting waterfowl, and collecting shellfish, roots, and seeds. Most of their region was treeless except for the cottonwoods, sycamores, and willows that lined the river channels and sloughs. Oaks did not extend very far onto the valley floor acorns were readily They were and, therefore, not available. generally obtained by trade with neighboring groups. Small land mammals and birds were only a small portion of the native diet and the Southern Valley Yokuts rarely ventured into the open country to capture antelope and elk. They did, however, capture many of the larger mammals when they came to the lakes and sloughs for water. Various cooking methods were employed. Tule roots and seeds were ground into meal, mixed with water, and stone-boiled in baskets. Fish and meat were broiled and roasted on coals and ashes. Small earth ovens were used to bake both vegetable and animal foods. Salt grass was used for seasoning. Firewood was at a premium and dried tules were usually substituted. TG&S ~l~ral ~s~rce Assessment 98-07r Ci~ of Bakersfield 6 Single family residences were constructed by using long poles, limbs, or sticks with one end set on the ground in an oval pattern, and the other ends brought together at the top to form a frame that was then covered with mats made from tule reeds. Some groups, using the same materials, built a distinctive long, steep-roofed communal house. This structure would shelter ten or more families. Each family would have a fireplace and outside door. Along the front of the house a long open shade porch was constructed and many of the domestic activities, such as cooking, were performed there. Additionally, each village had a communally-owned sweathouse. The men did their daily sweating and occasionally slept there. Clothing worn by the Southern Valley Yokuts was minimal. Males were either naked or used a breechcloth. Females wore a narrow fringed apron in front and a larger back piece. In cold weather both sexes wrapped themselves in skin cloaks. Generally feet were bare, though simple skin moccasins were used when traveling over rocky, brushy terrain. The hair was worn long by men and women and held in place by a string tied around the forehead. Women, who bore the heaviest burdens, wore basketry caps to protect the forehead from the tumpline band when carrying heavy burdens. Men carried loads in net backpacks held by a chest strap. Simple design tattooing was worn mainly by women. The design consisted of lines, zigzags, and rows of dots down the chin and across from the corners of the mouth. Children had their earlobes and nasal septa pierced for insertion of an ornament. The Yokuts technology was also shaped by the source of raw materials available. The very important tule provided the basis for their highest technological skill - basket weaving. The baskets varied in shape and use and included bowl-shaped cooking containers, conical burden baskets, flat winnowing trays, seed beaters, and a unique necked water bottle. Wood and stone crafts were quite undistinguished. Wood and many lithic materials were imported. Stone mortars and pestles were obtained by trade. Marine shells were secured from trade with coastal peoples and used for currency and personal adornment. Canoe-shaped rafts were constructed of dried tules and constituted the Yokuts favored mode of travel. The rafts could hold six people and their belongings. The basic domestic and economic unit in southern Valley Yokuts society was the nuclear family. The families were grouped TG&S ~l~ral Resource Assessment 98-07t Ci~ of Bakersfield 7 into patrilineal totemic lineages. A totem, an animal or bird, was a symbol representing the father's line. The totem was dreamed about, prayed to, and forbidden to kill or eat by that lineage, lineage was a transmitting The mechanism for offices, performing certain ceremonial duties, and creating mutual loyalties. These lineages were further organized into two moieties, or groups. The moieties had little to do with day-to- day life, but did serve certain functions. They would serve as opposing teams for games and as reciprocal groups in mourning rites and first-fruits ceremonies. Moiety exogamy was customary, but not absolute. There was no overall political unity among the tribes. They were split into self-governing local groups. Each group had a name, spoke a different dialect, and had a territory that was collectively owned. Some official positions were filled through patrilineal inheritance. In the Tachi tribe each settlement had a chief for each moiety and the pair shared equal authority. Generally groups were peaceful, Yokuts but occasional warfare did break out. Fighting was on a small scale and very little ritual was attached to warfare. There were four occasions regarded as significant and crucial in the life of each Yokuts: birth, a girl's puberty, marriage, and death. Each of these periods required special care, attention, and ceremony. One of the most important ceremonies was the ritual honoring the tribal dead. This usually took place annually, lasted six days, and included outside local groups. Guests came by the hundreds for the festival. The shamans were the only religious specialists of the Yokuts. They also served as "doctors." Many rituals were accompanied by songs and instrumental music. Musical instruments included the bone and cocoon rattle, wood whistle, flute, musical bow, and a cleft-stick rattle. The major artistic accomplishment of the Southern Valley Yokuts was the decorative patterns woven into their baskets. No significant number of Southern Valley Yokuts came under the control of the coastal Franciscan missionaries, however, significant impact to their culture resulted from infiltration of escaped natives from the missions. The runaways introduced foreign practices from their cultures which had suffered greatly from non-practice and practices acquired from the missions. Complete cultural breakdown and near-total disappearance of ~&$ ~l~ral Res~rce Assessment 98-07~ Ci~ of Bakersfield 8 native peoples from the San Joaquin Valley came with the annexation of California by the United States. The land passed into the hands of the settlers. The process was quickly relatively easy since the native peoples offered little effective resistance. Because of the early and rapid decimation of the Southern Valley Yokuts and the rapid collapse of their culture, there is relatively little published literature regarding them, and ethnographic descriptions obtained from aged informants is certainly incomplete. FIELD PROCEDURE A pedestrian survey of the 40 acre parcel proposed for the water facility was conducted by Catherine Lewis Pruett and Peggy B. Murphy on April 24, 1998 (Appendix II). The south property line is fenced. The other three property boundaries were flagged. Beginning in the southwest corner, transects were walked in an east/west direction and spaced approximately 25-30 meters apart. Spring vegetation, approximately 12-18 inches high, covered the 40 acre project area and consisted of a variety of native and non-native annuals and wildflowers. Ground squirrels, sheep droppings, rabbit pellets, coyote dens, and a fox den were observed on the property. Visibility on the 40 acre parcel was limited due to the high vegetation. However, the surface of the ground was visible in some areas. Visibility is estimated at 10-30%. Rodent burrows, dirt roads, and other bare areas were checked for cultural remains. The Morning Drive and Palidino Road alignments were driven on May 26, 1998. Vegetation was very high and thick (up to five feet) on both sides of the road. As most of the alignment had been previously surveyed, it was not.resurveyed. A small portion of each alignment that had not been included in previous surveys was inspected by Catherine Lewis Pruett and Dorothy Fleagle on May 26, 1998. The previously recorded site, CA-KER-2579, is located on a hill well above and outside the Morning Drive/bike path alignment. The northern end of the bike path alignment and the area for the holding ponds, 36 inch water pipe, and the intake structure ~&S ~l~ral ~s~rce Assessment 98-07, Ci~ of Bakersfield 9 had been previously surveyed. They were not resurveyed. RESULTS A mine shaft with associated cement footings was located along the bike path alignment on the east side of the canyon in the SE 1/4 of the SE 1/4 of Section 6, T. 29 S, R.39 E. Directly across the canyon to the west is a large cement foundation. Pictures of these historic features were shown to a long time Bakersfield resident and a geologist. Neither person could identify the features. At this point it is unclear how old the features are and exactly what their function was. No other historic sites or features were located. No prehistoric sites were found. The previously recorded site, CA- KER-2579, will not be impacted by this project. RECOMMENDATIONS It is recommended that further research be conducted on the mine shaft, footings, and foundation located along the bike path route. If they are more than 45 years old, they must be recorded as a historic archaeological site. Further assessment would then be needed to determine what impact the bike path project might have on the features. No further archaeological work is recommended for the remainder of this project. If, however, artifacts are found during construction, a qualified archaeologist should be consulted. If human remains are discovered at any time, work must halt and the Kern County coroner be contacted immediately (CEQA Appendix K VIII; Health and Safety Code 7050.5). The project archaeologist should also be contacted. !

Finger, Ph.D Project Scientist, Certified Paleontologist I I July 6, 1998 I I 1 SUMMARY This report summarizes the results of a paleontologic resources assessment of the proposed site south of the Kern River in northeast Bakersfield, Kern County, California. It is located in Sections 5, 6, 7, 8, and 18, T29S, R29E, and Sections 12 and 13, T29S, R28E, of the Oil Center Quadrangle (U.S. Geological Survey 7.5 minute series topographic map). A series of Miocene to Recent sediments characterize the local geology, which includes the Sharktooth Hill bonebed of extremely high paleontologic sensitivity. This nearly horizontal bonebed may be encountered at similar elevations in the canyon. Therefore, full-time mitigation 'monitoring for paleontologic resources is recommended during earth-disturbing activities along a half-mile segment of the canyon. 02160007.PALEO.doc I ! GEOLOGY AND PALEONTOLOGY I Geologic units mapped within the immediate area (Hanna, 1930; Keen, 1943; Hackel, 1965) are . · summarized below in accordance with stratigraphic revisions by Bartow and McDougall (1984): Quaternary alluvium/terraces (upper Pleistocene-Holocene) I These stream deposits comprise most of the designated map area, particularly in the southern part. Fossil occurrences in Quaternary alluvium are very spotty; elsewhere stream deposits have yielded Isignificant finds of mammoth, mastodon, bison, bear, lion, camel, horse, reptiles, birds, ground sloths, insects, and plants. Such discoveries are highly significant, but their infrequent occurrence and suggests this unit has low paleontologic sensitivity. I Kern River Formation (upper Miocene, Pliocene, and early Pleistocene?) I This unit consists of fluvio-lacustrme gravels, sands, and clays, and is described in detail by Bartow and Pittman (1983). It is exposed at high elevations in the northern half of the project area. Although there is potential to recover a diversity of significant terrestrial and freshwater fossils, the I of these sediments is low. paleontologic sensitivity generally I Chanac and "Santa Margarita" Formations (upper Miocene) The nonmarine Chanac Formation, which is distinguished by its buff to brown color, overlies the marine white sandstone of the "Santa Margarita" Formation. In the Tejon Hills, the Chanac has I yielded terrestrial vertebrates (Merriam, 1916) and the "Santa Margarita" bears late Miocene mollusks (Addicott, 1970). In the Kern River area, however, these formations appear to be nonfossiliferous. I Thus, their paleontologic sensitivities at the project site are probably low. Round Mountain Silt Member, Temblor Formation (middle Miocene) I The Round Mountain Silt is the youngest member of the Temblor Formation. Microfossil and strontium isotope data indicate that the Round Mountain Silt ranges from approximately 15.9 to 14 Ma I in this area (Olson, 1990). It is of particular paleontologic importance because its upper part includes the famous Sharktooth Hill bonebed. The bonebed ranges from four inches to nearly three feet in thickness, and is generally about a foot thick. One cubic foot of sediment may contain over 100 I individual bones and teeth! (Mitchell, 1963). It's vertebrate fauna of more than 100 species includes boney fish, cartilagenous fish (especially shark teeth), turtles, crocodiles, birds, sea lions, whales, and I desmostylians (an extinct hippo-like aquatic mammal), and terrestrial mammals such as tapir, horses, camel, "giraffe", mastodon, and rhinoceros (Mitchell, 1963, 1965). Sharktooth Hill (SW¼, SW¼, Sec. 25, T28S, R28E, elev. 643 feet) is approximately 1.4 miles northwest of the project area. I According to Dupras (1985, p. 147), "It is probably the most significant Miocene marine vertebrate locality in the world", and it is listed in the United States Landmark Registry. The bonebed extends I over ten square miles from north of Poso Creek to south of the Kern River. In the vicinity of the I 02160007. PALEO. doc 2 I project site, the unit is well-exposed in the bluffs facing the Kern County Soccer Park, where it has been extensively quarried for fossils. In addition to vertebrates, important invertebrate fossils have been recovered from the Round Mountain Silt in this region. The "Barker's Ranch fauna", the largest Miocene molluscan fauna of the Pacific Coast, extends from near the base of the Olcese Sand Member to the top of the Round Mountain Silt, and is the standard for the Temblor macrofossil stage (Addicott, 1965, 1970). All considered, the paleontologic sensitivity of the Round Mountain Silt in this area is extremely high. RECORDS SEARCH Dr. Sam MacLeod, Paleontology Collections Manager at the Los Angeles County Museum of Natural History (LACM), performed a localities search for recorded fossil sites in and around the designated area. Several vertebrate fossil localities are in Round Mountain Silt within the project area, and numerous localities are in the same rock unit north of the Kern River. Those in the vicinity of the project area on the south side of the river are located in Section 36, T28S, R28E (just north of the boundary of Section 6, T29S, R29E) and in Sections 5 and 6, T29S, R29E. The most prominent fossil locality in the project area is LACM 4874, the site of a major quarry excavation in late 1981 by LACM and Kern County Museum. It was the second of three major quarries in the Sharktooth Hill bonebed, which is usually less than a foot thick and lies at elevations between 600 and 700 feet. Many thousands of vertebrate fossils were recovered from the almost 40 square meters of bonebed excavated at LACM 4874. Two fossil baleen whales were discovered just above the bonebed at LACM 5767, also within the project area. Publications based on fossils collected at LACM localities in the project area are Barnes and Mitchell (1984) and Pfeil (1983). FIELD OBSERVATIONS Following the records search and study of pertinent geologic and paleontologic literature, Dr. Kenneth L. Finger, MBA Project Scientist and Certified Paleontologist, conducted a paleontologic field survey of the project area on June 29, 19!;}8. The survey involved inspection of surficial geology and slope exposures at the proposed intake structure, low lift station, pond, high lift station, and water treatment plant site and along the Hart Memorial Park conveyance pipeline, raw water pipeline, potable water pipeline, bike path, and access road. The few exposures encountered within the immediate vicinity of the delineated project were Quaternary terrace deposits of coarse sand and gravel in variable proportions. Many extensive exposures of greyish white Round Mountain Silt high up in the bluff facing Alfred Harrell Highway were farther "off track" but examined nonetheless, as were additional exposures at the base of the bluff (where diatomite is also present). Obviously quarried for fossils, not a single telltale fragment remained in any of these quarries. In the vicinity of the proposed Hart Memorial Park conveyance pipeline, a few small patches of coarse sand are visible in the shallow I 02160007.PALEO.doc 3 I ! I exposed banks of the currently high-running Kern River. A trackhoe was used to conduct soil tests at the proposed pond site. The trackhoe was observed excavating only sand before encountering water at a depth of 13 feet. During the 8-hour paleontologic field assessment, no fossiliferous material was I encountered. I CONCLUSIONS The only lithostratigraphic unit that has significant paleontologic sensitivity in the project area is the I Round Mountain Silt. Even though the Sharktooth Hill bonebed is usually less than a foot thick, potential faults in the project area could have varied the elevation of the bonebed. Based on the I records search and field observations, the portions of the proposed bike path, raw water pipeline, potable water pipeline, and access road to the water treatment plant site that are located between elevations 600 feet and 700 feet may result in significant impacts on paleontological resources. I RECOMMENDATIONS I Mitigation monitoring for paleontologic resources is recommended for the earth-disturbing activities on the northeast Bakersfield site between the elevations of 600 and 700 feet. The program must I conform the of Kern the of Vertebrate and to guidelines County, Society Paleontologists, NEPA, CEQA. This program must include but not be limited to the following measures: I 1. Assign one paleontologic monitor, trained and equipped to allow the rapid removal of fossils with minimal construction delay, to the site full-time during the interval of earth-disturbing I activities at elevations between 600 and 700 feet. I 2. Should fossils be found within an area being cleared or graded, divert earth-disturbing activities elsewhere until the monitor has completed salvage. If construction personnel make the discovery, the grading contractor should immediately divert construction and call the I monitor to the site. Major salvage time may be shortened by grading contractor's assistance (e.g., removal of overburden, lifting and removing large and heavy fossils). I 3. Prepare, identify, and curate all recovered fossils. I 4. Upon completion of grading, prepare summary report documenting mitigation and results, with itemized inventory of collected specimens. Submit report to client, designated I depository, and any other appropriate agency, and transfer fossil collection to an appropriate depository. Submittal of this report to the appropriate lead agency signifies completion of the I program to mitigate impacts on paleontologic resources. I 02160007.PALEO.doc 4 I These measures would mitigate adverse ground-disturbing impacts on paleontologic resources in the site by ensuring the recovery of highly important fossil remains and associated scientific data, their preservation in a recognized depository, and their availability for future study by qualified investigators. These specimens artd data might otherwise be destroyed as a result of the clearing and grading activities that would accompany the construction. If appropriate mitigation measures were to be initiated, fresh bedrock exposed by grading could reveal previously hidden fossils that can be collected. If any recovered fossil represents a new species or one not previously recorded in the region, it is an extremely important find, as it is a significant addition to our knowledge of regional paleontology. Implementation of the foregoing mitigation measures should ensure that any potential adverse impacts on paleontologic resources in the si~te will be reduced to an insignificant level. The mitigation process enables a representative sampling of any fossils which may be present, so that a scientific record is available for future investigations after the bedrock is removed or obscured by grading and construction. 02160007.PALEO.doc 5 REFERENCES CITED Addicott, W.
