BOX 1969 BAKERSFIELD, CALIFORNIA 93303 PREPARED BY BROWN-BUNTIN ASSOCIATES, INC. VISALIA, CALIFORNIA JUNE 1, 2015 406 W. School Avenue · Visalia, CA 93291 · (559) 627-4923 · (559) 627-6284 Fax 14-015 (Proposed Commercial Development, Bakersfield) 6-1-15 2 1. INTRODUCTION Project Description: The project is a proposed commercial development consisting of approximately 800,000 square feet of retail shopping space with an additional 240-room hotel. The project will be developed in two phases, with the first phase scheduled for completion in 2017 and full build-out in 2020. The first phase will include 400,000 square feet of commercial retail space and the second phase will include an additional 400,000 square feet of commercial retail space and a 240-room hotel. Location: The 85-acre project site is located east of State Route 99 (SR 99) along the west side of South H Street between Hosking Avenue and Berkshire Road in southeastern Bakersfield. The project vicinity is shown as Figure 1. Environmental Noise Assessment: This environmental noise assessment has been prepared to determine if significant noise impacts will be produced by the project and to describe mitigation measures for noise if significant impacts are determined. The environmental noise assessment, prepared by Brown-Buntin Associates, Inc. (BBA), is based upon the project site plan dated June 10, 2014 (Figure 2), a traffic study prepared by Ruettgers and Schuler dated October 20141 and a project site visit on May 14, 2014. Revisions to the site plan, traffic study or other project-related information available to BBA at the time the analysis was prepared may require a reevaluation of the findings and/or recommendations of the report. Appendix A provides definitions of the acoustical terminology used in this report. Unless otherwise stated, all sound levels reported in this analysis are A-weighted sound pressure levels in decibels (dB). A-weighting de-emphasizes the very low and very high frequencies of sound in a manner similar to the human ear. Most community noise standards utilize A-weighted sound levels, as they correlate well with public reaction to noise. 2. THRESHOLDS OF SIGNIFICANCE The CEQA Guidelines indicate that significant noise impacts occur when the project exposes people to noise levels in excess of standards established in local noise ordinances or general plan noise elements, or causes a substantial permanent or temporary increase in noise levels above levels existing without the project. a. Noise Level Standards City of Bakersfield The project site lies within the City of Bakersfield. The applicable standards for noise levels that apply to this project are contained within Chapter VII of the Metropolitan Bakersfield General Plan2, adopted in 2002. 14-015 (Proposed Commercial Development, Bakersfield) 6-1-15 3 For transportation noise sources (e.g., traffic and railway noise), the noise element sets a standard of 65 dB CNEL at the exterior of noise-sensitive uses. Noise-sensitive uses include residences, schools, hospitals, transient lodging and recreational areas. An interior noise standard of 45 dB CNEL applies within interior living spaces. For non-transportation noise sources (e.g., commercial property), the noise element applies hourly noise levels performance standards at residential and other noise-sensitive uses. Table I summarizes the applicable hourly noise level standards. TABLE I HOURLY NOISE LEVEL PERFORMANCE STANDARDS STATIONARY NOISE SOURCES METROPOLITAN BAKERSFIELD GENERAL PLAN Maximum Acceptable Noise Level, dB Min./Hr. (Ln) Day (7a-10p) Night (10p-7a) 30 (L50) 55 50 15 (L25) 60 55 5 (L8.3) 65 60 1 (L1.7) 70 65 0 (Lmax) 75 70 Note: Ln means the percentage of time the noise level is exceeded during an hour. L50 means the level exceed 50% of the hour, L25 is the level exceed 25% of the hour, etc. Source: Metropolitan Bakersfield General Plan Additionally, The City of Bakersfield General Plan Noise Element sets standards for project-related noise impacts and cumulative noise impacts from mobile (transportation-related) noise sources affecting existing noise-sensitive land uses. The City utilizes the standards listed below in impact determination in regards to increases in ambient noise levels at existing noise-sensitive land uses resulting from project-related transportation noise sources. Standards For Project-Related Noise Impacts From Mobile Sources A significant increase of existing ambient noise levels affecting existing noise-sensitive land uses (receptors), and requiring the adoption of practical and feasible mitigation measures, is deemed to occur where a project will cause:  An increase of the existing ambient noise level by 5 dB or more, where the existing ambient level is less than 60 dB CNEL;  An increase of the existing ambient noise level by 3 dB or more, where the existing ambient level is 60 to 65 dB CNEL;  An increase of the existing ambient noise level by 1.5 dB or more, where the existing ambient level is greater than 65 dB CNEL 14-015 (Proposed Commercial Development, Bakersfield) 6-1-15 4 Standards For Cumulative Noise Impacts From Mobile Sources The project’s contribution to noise increases would normally be considered cumulatively considerable and significant when ambient noise levels affect noise sensitive land uses (receptors) and when the following occurs.  A project increases the ambient (cumulative without project) noise level by 1 dB or more; and  The cumulative with project noise level cause the following: o An increase of the existing ambient noise level by 5 dB or more, where the existing ambient level is less than 60 dB CNEL; o An increase of the existing ambient noise level by 3 dB or more, where the existing ambient level is 60 to 65 dB CNEL; o An increase on the existing ambient noise level by 1.5 dB or more, where the existing ambient level is greater than 65 dB CNEL. State of California There are no state noise standards that are applicable to the project. Federal Noise Standards There are no federal noise standards that are applicable to the project. b. Construction Noise and Vibration Section 9.22.050 of the Bakersfield Municipal Code3 limits construction to the hours of 6:00 a.m. to 9:00 p.m. on weekdays, and between 8:00 a.m. and 9:00 p.m. on weekends, when construction is within 1,000 feet of a residence. Certain exceptions to these hours are specified in the code. The City of Bakersfield does not have regulations that define acceptable levels of vibration. One of the most recent references suggesting vibration guidelines is the California Department of Transportation (Caltrans) Transportation and Construction Vibration Guidance Manual4. The Manual provides guidance for determining annoyance potential criteria and damage potential threshold criteria. These criteria are provided below in Table III and Table IV, and are presented in terms of peak particle velocity (PPV) in inches per second (in/sec). 14-015 (Proposed Commercial Development, Bakersfield) 6-1-15 5 TABLE III GUIDELINE VIBRATION ANNOYANCE POTENTIAL CRITERIA Human Response Maximum PPV (in/sec) Transient Sources Continuous/Frequent Intermittent Sources Barely Perceptible 0.04 0.01 Distinctly Perceptible 0.25 0.04 Strongly Perceptible 0.9 0.1 Severe 2.0 0.4 Source: Caltrans TABLE IV GUIDELINE VIBRATION DAMAGE POTENTIAL THRESHOLD CRITERIA Structure and Condition Maximum PPV (in/sec) Transient Sources Continuous/Frequent Intermittent Sources Extremely fragile, historic buildings, ancient monuments 0.12 0.08 Fragile buildings 0.2 0.1 Historic and some old buildings 0.5 0.25 Older residential structures 0.5 0.3 New residential structures 1.0 0.5 Modern industrial/commercial buildings 2.0 0.5 Source: Caltrans 3. SETTING The project site and surrounding area is generally flat. The area immediately adjacent to the project site is comprised predominantly of single-family residential land uses, with commercial land uses north of the project site and SR 99 west of the project site. The dominant source of existing noise in the project vicinity is traffic noise from SR 99 and from nearby local roadways. Meadows Field Airport is located approximately 10 miles north of the project site. The project site is located less than 2 miles northeast of a small, unattended private-use airstrip (Costerisan Farms Airport). It should be noted that the airport is not recognized in the Kern County Airport Land Use Compatibility Plan (November 13, 2012) and no data regarding flight operations is known at this time. a. Background Noise Level Measurements Measurements of existing ambient noise levels in the project vicinity were conducted at three locations within the project site on May 14, 2014 and two additional locations in the project vicinity of January 20, 2015. Noise monitoring equipment consisted of a Larson-Davis Laboratories Model LDL 820 sound level analyzer equipped with a Bruel & Kjaer (B&K) Type 14-015 (Proposed Commercial Development, Bakersfield) 6-1-15 6 4176 ½” microphone. The microphone was mounted on a tripod at approximately five (5) feet above the ground and was equipped with a random incidence corrector so that noise from sources in all directions could be accurately measured. The monitor was calibrated with a B&K Type 4230 acoustical calibrator to ensure the accuracy of the measurements. The equipment complies with applicable specifications of the American National Standards Institute (ANSI) for Type 1 sound measurement systems. The locations of the measurement sites are shown in Figure I. Table V summarizes measured noise levels. Traffic was the only identifiable noise source. It should be noted that at the time of measurement, an existing, large berm of soil was present between Site # 3 and SR 99, which provided acoustical shielding from traffic noise on SR 99. Therefore, noise levels reported for Site # 3 are lower than what would normally be expected at that location. Site 1 and Site 2 were intended to provide representative ambient noise levels to the backyard areas of the homes located on the east side of H Street. Due to the existing canal that parallels H Street, access to the area near those backyards was not possible. Site 1 and Site were located at the approximately 200 feet from the centerline of H Street, the same approximate distance as the backyards of the residences located east of H Street. Additionally, Site 1 was located in the vicinity of a proposed hotel within the project site. Sites 4 and 5 were located off-site within the general project vicinity.

Existing Traffic Noise Levels Noise levels from traffic on roadways in the project vicinity were calculated for existing conditions using the Federal Highway Administration (FHWA) Highway Traffic Noise Prediction Model and traffic data obtained from the traffic study prepared by Ruettgers and 14-015 (Proposed Commercial Development, Bakersfield) 6-1-15 7 Schuler. Noise levels from traffic on State Road 99 (SR) were predicted using data obtained from Caltrans. The FHWA Model is a standard analytical method used for roadway traffic noise calculations. The model is based upon reference energy emission levels for automobiles, medium trucks (2 axles) and heavy trucks (3 or more axles), with consideration given to vehicle volume, speed, roadway configuration, distance to the receiver, and the acoustical characteristics of the site. The FHWA Model was developed to predict hourly Leq values for free-flowing traffic conditions, and is generally considered to be accurate within ±1.5 dB. To predict CNEL values, it is necessary to determine the hourly distribution of traffic for a typical day and adjust the traffic volume input data to yield an equivalent hourly traffic volume. The FHWA Model assumes a clear view of traffic with no shielding at the receiver location. Additional noise level monitoring and concurrent traffic counts were conducted by BBA at two locations in the project vicinity on December 15, 2014. The purpose of the noise monitoring was to evaluate the accuracy of the FHWA Model in describing noise exposure from traffic on local roadways in the project vicinity. One measurement was conducted along Panama Lane between South H Street and South Union Avenue, at a distance of 75 feet from the centerline of Panama Lane. A second measurement was conducted along Hosking Avenue between South H Street and South Union Avenue, at a distance of 50 feet from the centerline of the roadway. Noise measurements were conducted in terms of the equivalent energy sound level (Leq). Measured Leq values were compared to Leq values calculated (predicted) by the FHWA Model using as inputs the traffic volumes, truck mix and vehicle speed observed during the noise measurements. The results of that comparison are shown in Table VI. From Table VI it may be determined that the predicted traffic noise level was the same as the measured noise level along Panama Lane and 0.1 dB higher than the measured noise level along Hosking Avenue, for the traffic conditions observed at the time of the noise measurements. This is considered an excellent prediction by the model and no adjustments to the model are necessary. 14-015 (Proposed Commercial Development, Bakersfield) 6-1-15 8 TABLE VI COMPARISON OF MEASURED AND PREDICTED (FHWA MODEL) NOISE LEVELS PROPOSED HOSKING AND 99 COMMERCIAL DEVELOPMENT-PROJECT VICINITY DECEMBER 15, 2014 Panama Lane Hosking Avenue Measurement Date 12/15/14 12/15/14 Measurement Start Time 1:40 p.m. 2:05 p.m. Observed # Autos/Hr. 1164 336 Observed # Medium Trucks/Hr. 12 12 Observed # Heavy Trucks/Hr. 48 12 Posted Speed (MPH) 45 45 Distance, ft.

Annual Average Daily Traffic (AADT) volumes were obtained from the above-referenced traffic study. The day/evening/night distribution of traffic and the percentages of trucks on the roadways used for modeling were obtained from similar studies BBA has conducted in the area. Noise attenuation provided by existing noise barriers along the analyzed roadways were taken into consideration. For a typical 6-foot wall along most roads, the reduction is about 5 dB. Appendix B summarizes the noise modeling data used to calculate traffic noise exposure for existing conditions in the project area. The traffic noise modeling data summarized by Appendix B represent the best information known to BBA at the time this analysis was prepared. Table VII summarizes calculated traffic noise exposure for existing traffic conditions along roadways in the project area. Shown are the calculated CNEL values at a typical residential setback along the roadways (75 feet from the center of the roadway). The existing CNEL value for SR 99 in the project vicinity was calculated for a setback of 150 feet from the center of the roadway. 14-015 (Proposed Commercial Development, Bakersfield) 6-1-15 9 TABLE VII EXISTING (2014) TRAFFIC NOISE LEVELS VICINITY OF PROJECT SITE AT SOUTH H STREET AND HOSKING AVENUE, BAKERSFIELD Roadway Name CNEL, dB1 Berkshire Rd : S.

Project related traffic volumes for SR 99 was not available. Source: Brown-Buntin Associates, Inc. 14-015 (Proposed Commercial Development, Bakersfield) 6-1-15 14 A significant noise impact is considered to occur when there is a significant increase in ambient noise levels due to the project. The City of Bakersfield utilizes the standards provided in Table II of this report for the determination of significant impacts resulting from project-related transportation noise sources. Tables VIII, IX and X indicate that project-related changes in traffic noise levels will be less than significant at all off-site locations. It should be noted that along Hosking Avenue between SR 99 and South H Street (2017 and 2020 conditions), transportation noise sources do result in an increase in noise greater than 1.5 dB in an area where existing ambient noise levels are 65 dB or greater, however, there are no residential land uses (sensitive receivers) along Hosking Avenue between SR 99 and South H Street. Additionally, the land adjacent to this section of roadway is not zoned for residential uses, and there are no future planned residential uses along this section of roadway. Therefore, no impacts would occur to noise sensitive land uses along this roadway. b. Noise Impacts from On-Site Noise Sources (Less Than Significant) Sources of noise from the shopping center could potentially include truck deliveries, loading docks, parking lot vehicle movements, air conditioners, and trash compactors. Information about the number of truck deliveries to stores on site is limited. The only identified commercial use is a Bass Pro Shops store. According to a Bass Pro representative, one truck delivery per week will occur at the store. No information on truck deliveries is available for the “anchor” store or the remaining retail stores. Figure 2 shows conceptual store locations on the site. Based on the placement of stores along the eastern side of the site, the distance from probable truck delivery routes to the nearest residences is approximately 350 feet. File data for slowly moving heavy trucks indicate that the maximum noise level (Lmax) is approximately 73 dB at 50 feet. Truck movements that do not occur on a public roadway are considered to be a stationary noise source. Accounting for distance to residences and the attenuation provided by the existing block wall bordering the residences, the Lmax in yards of residences is estimated to be about 55 dB. This level is below the 75 dB (daytime) and 70 dB (nighttime) Lmax criteria in the noise element. Therefore, noise levels from on-site truck movements will be less than significant. Any loading docks will be located no closer than 350 feet from the residences. File data for loading docks where refrigerated trucks unload indicate that at 75 feet the L50 noise level during a busy hour of activity is 57 dB. Accounting for distance and the existing wall, the estimated L50 at the nearest residential yards is about 39 dB. This is below the daytime L50 55 dB and nighttime 50 dB noise element criteria (Table I) for this type of stationary noise source. Therefore, noise levels from loading dock activities will be less than significant. Noise due to traffic in parking lots is typically limited by low speeds and is not usually considered to be significant. Human activity in parking lots that can produce noise includes voices, stereo systems and the opening and closing of car doors and trunk lids. Such activities can occur at any time. The noise levels associated with these activities cannot be precisely defined due to variables such as the number of parking movements, time of day and other factors. It is typical for a passing car in a parking lot to produce a maximum noise level of 60 to 65 dBA at a distance of 50 feet, which is comparable to the level of a raised voice. For this 14-015 (Proposed Commercial Development, Bakersfield) 6-1-15 15 project, the closest proposed parking would be located approximately 300 feet from the closest existing homes. It should be noted that the closest parking lots to nearby noise-sensitive land uses are relatively small, with the majority of parking occurring toward the center of the project site, in a location where parking lot noise would be shielded from noise-sensitive land uses by the intervening commercial and hotel buildings. Parking lot noise would not be expected to exceed the standards of the city’s noise element or contribute to overall ambient noise levels. Detailed information about air conditioners and trash compactors is not available at this time. Based upon noise studies conducted by BBA for other projects, the maximum noise level produced by a typical un-enclosed trash compactor (Hydra-Fab Model 1200) is approximately 74 dBA at a distance of 10 feet from the equipment, or approximately 45 dBA at a distance of 300 feet (approximate distance from closest proposed store to nearby homes). Since trash compactors operate intermittently, they would not produce noise levels in excess of the City’s performance standards at the closest homes. Trash compactors would also not exceed the daytime or nighttime maximum noise level standards of the city’s noise ordinance at the closest existing homes. It can be assumed that the project would include roof-mounted HVAC units on commercial buildings. Based upon data from large stores similar to those proposed for the project, it is estimated that noise levels from roof-mounted HVAC units at the closest homes to the project site would be in the range of 40-45 dBA. This does include consideration of acoustic shielding provided if the building included parapets around roof-mounted HVAC units. These levels would not be audible above existing ambient noise levels at the nearby homes and they do not exceed the City’s performance standards. c. Noise from Construction (Less Than Significant With Mitigation) Construction noise could occur at various locations within and near the project site through the build-out period. During the construction of the project, noise from construction activities would potentially impact noise-sensitive land uses in the immediate area. The distance from the closest residence to the project site is approximately 300 feet. Table XI provides typical construction- related noise levels at distances of 50 feet, 100 feet, and 300 feet. Construction activities would be temporary in nature and would most likely occur only 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. 14-015 (Proposed Commercial Development, Bakersfield) 6-1-15 16 TABLE XI TYPICAL CONSTRUCTION EQUIPMENT MAXIMUM NOISE LEVELS, dBA Type of Equipment 50 Ft.100 Ft.300 Ft.

Additionally, BBA utilized the FHWA Roadway Construction Noise Model (RCNM) to quantify potential noise levels that could occur at nearby residences during the various phases of construction. The RCNM is considered to be a construction noise screening tool and is based upon construction noise measurements conducted during the construction of the Central Artery/Tunnel (CA/T) Project in Boston in the early 1990s. The model assumes percentages of usage times that are typical for the various types of construction equipment and provides noise levels in terms of the Leq. Noise levels reported in Table XII reflect those which could be expected at a distance of 300 feet from construction activities, the approximate distance from the project site to the closest residences, for the assumed construction schedule. Noise levels reported in Table XII also consider acoustic shielding provided by existing sound walls along the nearby residences. 14-015 (Proposed Commercial Development, Bakersfield) 6-1-15 17 TABLE XII ASSUMED PROJECT CONSTRUCTION EQUIPMENT SCHEDULE NOISE LEVELS, dBA Phase Equipment Total Number of Days Leq, dBA Site Preparation (6/1/15-6/19/15) 3 Rubber Tired Dozers 15 65 4 Tractors/Loaders/Backhoes 15 Grading (6/19/15-8/7/15) 2 Excavators 35 67 1 Grader 35 1 Rubber Tired Dozer 35 2 Scrapers 35 2 Tractors/Loaders/Backhoes 35 Building Construction (8/7/15-7/22/16) 1 Crane 250 64 3 Forklifts 250 1 Generator Set 250 3 Tractors/Loaders/Backhoes 250 1 Welder 250 Paving (7/22/16-9/9/16) 2 Pavers 35 64 2 Pieces of Paving Equipment 35 2 Rollers 35 Painting (9/9/16-10/28/16) 1 air compressor (6 hours/day) 35 53 Site Preparation (1/1/17-1/27/17) 3 Rubber Tired Dozers 20 65 4 Tractors/Loaders/Backhoes 20 Grading (1/27/17-3/30/17) 2 Excavators 45 67 1 Grader 45 1 Rubber Tired Dozer 45 2 Scrapers 45 2 Tractors/Loaders/Backhoes 45 Building Construction (3/30/17-9/5/18) 1 Crane 375 64 3 Forklifts 375 1 Generator Set 375 3 Tractors/Loaders/Backhoes 375 1 Welder 375 Paving (9/5/18-10/23/18) 2 Pavers 35 64 2 Pieces of Paving Equipment 35 2 Rollers 35 Painting (10/23/18-12/10/18) 1 air compressor (6 hours/day) 35 53 Source: FHWA Roadway Construction Noise Model Insight Environmental Consultants Prediction of construction noise levels as described by the statistical criteria of the City’s noise performance standards (Table I) are not quantified by the RCNM. However, there is a potential under some circumstances that construction noise could temporarily exceed the City’s performance standards and therefore be significant. Temporary increases in traffic noise levels as a result of construction crews and equipment entering and exiting the project site could occur, and would most likely take place during the morning and evening hours of commute. Estimates of these temporary increases were not provided in the project traffic study; therefore, quantifying the actual increases in construction- 14-015 (Proposed Commercial Development, Bakersfield) 6-1-15 18 related traffic noise levels was not possible. Due the transient nature of potential construction- related traffic noise increases, it would not be considered a significant impact to nearby noise- sensitive land uses. Mitigation Mitigation of construction noise may be accomplished by complying with the city’s construction noise ordinance, which limits construction hours to 6:00 a.m. to 9:00 p.m. on weekdays and 8:00 a.m. to 9:00 p.m. on weekends, where construction occurs within 1000 feet of a residence. In addition, all construction equipment should be equipped with adequate mufflers and be properly maintained. d. Vibration Impacts (Less Than Significant) The dominant sources of man-made vibration are sonic booms, blasting, pile driving, pavement breaking, demolition, diesel locomotives, and rail-car coupling. None of these sources are anticipated from the project site. Vibration from construction activities could be detected at the closest sensitive land uses, especially during movements by heavy equipment or loaded trucks and during some paving activities. The closest existing residences to the project site are located approximately 300 feet to the west. Typical vibration levels at distance of 300 feet are summarized by Table XIII. TABLE XIII TYPICAL VIBRATION LEVELS DURING CONSTRUCTION PPV (in/sec) Equipment @ 300´ Bulldozer (Large) 0.006 Bulldozer (Small) 0.00019 Loaded Truck 0.005 Jackhammer 0.002 Vibratory Roller 0.013 Caisson Drilling 0.006 Source: Caltrans Table XIII indicates that the equipment with the highest potential vibration levels would be a vibratory roller. The estimated equipment schedule presented in Table XII indicates that a roller would be used for approximately 35 days during each of the two phases of construction. While in use, the roller could produce vibration levels of approximately 0.013 PPV (in/sec) at the closest residence. As described in Table III and Table IV, such levels would not be expected to cause damage to any of the described building types and would be “barely noticeable” at the closest residence if the equipment was used continuously or frequently. Such levels are not considered to be a significant impact. After full project build out, it is not expected that ongoing operational activities will result in any vibration impacts at nearby sensitive uses. Activities involved in trash bin collection could result 14-015 (Proposed Commercial Development, Bakersfield) 6-1-15 19 in minor on-site vibrations as the bin is placed back onto the ground. Such vibrations would not be expected to be felt at the closest off-site sensitive uses. e. Noise Impacts to On-Site Proposed Noise-Sensitive Uses (Less Than Significant) The proposed commercial development includes two proposed hotels to be located in the northeast corner of the project site. The location of the proposed hotels is provided in Figure 2. Transient lodging (hotels and motels) are considered to be a noise-sensitive land use as described by the City’s Noise Element. The Noise Element establishes an exterior noise level standard of 65 dB CNEL and an interior noise level standard of 45 dB CNEL. The exterior noise level standard of 65 dB CNEL would be applied to common outdoor activity areas of the hotel such as the pool area or common courtyard. At the time of this analysis, specific design details for the proposed hotels were not known. The approximate distance from the exterior of the proposed hotel to South H Street is 150 feet from the centerline of the roadway. Using the above-described FHWA traffic model, the future (2035) with project traffic noise exposure at the exterior of the closest façade facing South H Street is approximately 64.4 dB CNEL. At this setback from the roadway, the exterior noise impact would be less than significant. A specific analysis of interior noise levels was not performed. However, it may be assumed that commercial construction methods complying with current building code requirements will reduce exterior noise levels by a minimum of 25 dB if windows and doors are closed. Therefore, compliance with the noise element would require a minimum outdoor-to-indoor noise level reduction (NLR) of 19.4 dB (64-45=19.4). This will be sufficient for compliance with the City’s 45 dB CNEL interior noise level standard. f. Noise Impacts From Nearby Private Airstrip (Less Than Significant) The proposed project site is located less than two miles northeast of a small, privately operated airstrip (Costerisan Farms Airport). As previously described, the airport is not recognized in the Kern County Airport Land Use Policy Plan, and operational data is not known. It is not anticipated that operations from the airstrip would generate substantial noise levels at the project site; therefore, the impact would be less than significant. 5. CUMULATIVE NOISE IMPACTS (NOT CUMULATIVELY CONSIDERABLE) Table XIV compares existing (2014) traffic noise levels to 2035 (with project) traffic noise levels. The city’s criteria for determining cumulative noise impacts for mobile sources indicate than cumulative noise levels will not be cumulatively considerable at any location. 14 - 0 1 5 ( P r o p o s e d C o m m e r c i a l D e v e l o p m e n t , B a k e r s f i e l d ) 6 - 1 - 1 5 20 TA B L E X I V YE A R 2 0 3 5 C U M U L A T I V E T R A F F I C N O I S E A N A L Y S I S CN E L ( d B ) A T 7 5 F E E T F R O M C E N T E R O F R O A D W A Y Ro a d w a y N a m e 20 1 4 No P r o j e c t 20 3 5 Wi t h P r o j e c t Ch a n g e , dB 20 3 5 No P r o j e c t 20 3 5 Wi t h P r o j e c t Change, dB Cumulatively Considerable?

In this context, the ambient noise level constitutes the normal or existing level of environmental noise at a given location. CNEL: Community Noise Equivalent Level. The average equivalent sound level during a 24-hour day, obtained after addition of approximately five decibels to sound levels in the evening from 7:00 p.m. to 10:00 p.m. and ten decibels to sound levels in the night before 7:00 a.m. and after 10:00 p.m. DECIBEL, dB: A unit for describing the amplitude of sound, equal to 20 times the logarithm to the base 10 of the ratio of the pressure of the sound measured to the reference pressure, which is 20 micropascals (20 micronewtons per square meter). DNL/Ldn: Day/Night Average Sound Level. The average equivalent sound level during a 24-hour day, obtained after addition of ten decibels to sound levels in the night after 10:00 p.m. and before 7:00 a.m. Leq: Equivalent Sound Level. The sound level containing the same total energy as a time varying signal over a given sample period. Leq is typically computed over 1, 8 and 24-hour sample periods. NOTE: The CNEL and DNL represent daily levels of noise exposure averaged on an annual basis, while Leq represents the average noise exposure for a shorter time period, typically one hour. Lmax: The maximum noise level recorded during a noise event. Ln: The sound level exceeded "n" percent of the time during a sample interval (L90, L50, L10, etc.). For example, L10 equals the level exceeded 10 percent of the time. 14-015 (Proposed Commercial Development, Bakersfield) 6-1-15 A-2 ACOUSTICAL TERMINOLOGY NOISE EXPOSURE CONTOURS: Lines drawn about a noise source indicating constant levels of noise exposure. CNEL and DNL contours are frequently utilized to describe community exposure to noise. NOISE LEVEL REDUCTION (NLR): The noise reduction between indoor and outdoor environments or between two rooms that is the numerical difference, in decibels, of the average sound pressure levels in those areas or rooms. A measurement of Anoise level reduction@ combines the effect of the transmission loss performance of the structure plus the effect of acoustic absorption present in the receiving room. SEL or SENEL: Sound Exposure Level or Single Event Noise Exposure Level. The level of noise accumulated during a single noise event, such as an aircraft overflight, with reference to a duration of one second. More specifically, it is the time-integrated A-weighted squared sound pressure for a stated time interval or event, based on a reference pressure of 20 micropascals and a reference duration of one second. SOUND LEVEL: The sound pressure level in decibels as measured on a sound level meter using the A-weighting filter network. The A-weighting filter de-emphasizes the very low and very high frequency components of the sound in a manner similar to the response of the human ear and gives good correlation with subjective reactions to noise. SOUND TRANSMISSION CLASS (STC): The single-number rating of sound transmission loss for a construction element (window, door, etc.) over a frequency range where speech intelligibility largely occurs. 14-015 (Proposed Commercial Development, Bakersfield) 6-1-15 APPENDIX B TRAFFIC NOISE MODELING ASSUMPTIONS Br o w n - B u n t i n A s s o c i a t e s , I n c FH W A - R D - 7 7 - 1 0 8 Ca l c u l a t i o n S h e e t s Oc t o b e r 2 9 , 2 0 1 4 Pr o j e c t # : 1 4 - 0 1 5 Co n t o u r L e v e l s ( d B ) 60 6 5 7 0 7 5 De s c r i p t i o n : Ex i s t i n g ( 2 0 1 4 ) Ld n / C n e l : CN E L Si t e T y p e : S o f t Se g m e n t R o a d w a y N a m e S e g m e n t D e s c r i p t i o n A D T % D a y % E v e n i n g % N i g h t % M e d % H e a v y S p e e d D i s t a n c e O f f s e t 1 Be r k s h i r e R d S .
