The meeting was called to order by Boardmember Salvaggio at 4:35pm. 2. Present: Mark Salvaggio, Chair Patricia M. Smith, Vice-Chair Jacquie Sullivan (seated at 4:40pm) 3. 'Boardmember Smith made a motion to approve the minutes of the Special Meeting held May 8, 1997. Motion carded. 4. Mr. Core introduced Mary Lou Cotton fi.om the Kem County Water Agency who brought the Board up-to-date on items of concern regarding the CALFED process. The Califomia/Federal work groups are discussing issues of the Sacramento-San Joaquin River Delta which may have an effect on urban water users in Bakersfield. Part of the CALFED process is to solidify water concems in terms of delta diversions by water projects. A proposed water use efficiency program would affect all urban water agencies that have 3,000 or more service connections. Mr. Core stated that the City water system is already complying with the intent and spirit of the state-wide proposals and has followed through with conservation measures from its Urban Water Management Plans. For Board information only, no action required. 5. Deferred business 5A. Hydrographic Supervisor Steve Lafond gave an update on the Kem River operations. Isabella Reservoir peaked on June 6 at just under 492,000 acre-feet. The April-July runoff is on schedule at approximately 125%. A normal drawdown schedule is expected to bring the winter carryover level to 245,000 acre-feet. There is an oceanic warm water condition (El Nino effect) which may bring unusually heavy rains this winter. For information only, no action required. 5B. A brief update on the Southwestern Willow Flycatcher habitat designation was presented by Mr. Core. The Kern River Research Center is reporting the 1997 count of the Brown- Headed Cowbird, a predator of the SW Flycatcher, is steadily declining. The cowbird -1- trapping efforts of the Kern River Research Center in sponsorship with the California Department of Fish and Game and the Kern River Interests has been very successful. The goal of Kern River Interests involvement in this effort is to affect the decision of the U. S. Fish & Wildlife Service to not designate the shoreline around Lake Isabella as a designated habitat for the SW Flycatcher. A final habitat designation from the U. S. Fish & Wildlife Service is expected by July 17th, 1997. For Board information, no action required. 6. New Business 6A. The consideration of a City contribution to the "Panorama Vista" property acquisition was presented before the Board by Mr. Bogart. An association consisting of the Kern River Access Committee, the Kern River Parkway Foundation and the Kem River Equestrians for the Preservation of Trails are attempting to raise funds to acquire parcels of ARCO Kern River property located in and along the river between Manor Street and Gordon's Ferry Bridge. One condition of the sale is that the property has to be acquired by July 31, 1997. Mr. Thomas Fallgatter represents the Panorama Vista group and indicated to the Board that pledges are coming in from private contributions and the group is relUctant to accept any donations if there are conditions attached. At this time, contributions have been pledged to cover the entire amount, but have not yet been received. The City Water Resources Department has an ongoing program to acquire floodplain properties and has discussed an offer to contribute money to the group in exchange for the designated floodway portion of ,' the property. The floodway land is estimated to be worth $28,000. It is staff's : recommendation that the City Water Resources Department be a backstop to contribute the money to purchase the flood plain acreage if the necessary funds cannot be raised by the group in time. A motion was made by Boardmember Smith to this effect. Motion carried. 6B. Mr. Bogart presented to the Board a Kern River flood plain property acquisition agreement from Carosella Properties, Inc. The property is located just west of the Stockdale Highway bridge over the Kern River. Mr. Tom Carosella of Carosella Properties, Inc. wrote to the City Manager offering to transfer ownership of about 45 acres of primary and secondary flood way property to the City of Bakersfield in exchange for the City constructing a levee to protect lands to the south of that point. The City would be able to construct the levee at a lesser cost with its own forces using the available sand in the river. Mr. Fallgatter representing the Kern River Parkway Foundation, requested that a provision be in the agreement to protect the flood plain property from new development to allow it to remain in natural condition. Mr. Bogart agreed that would be possible, but that it may be necessary to build a turnout structure on the property to control the water flow onto the flood plain for groundwater recharging. Staff will incorporate the necessary language in the agreement for these provisions. The Board recommends City Council approval of the agreement. C. A proposal to cost split an engineering design for a water supply and treatment project for the Northeast Bakersfield area was brought before the Board by Mr. Core. Mr. Core gave a brief background and history of the project to the Board. California Water Service -2- Company has asked the City to participate in the cost for a preliminary engineering design for an intermediate treatment plant to serve the area east of Morning Drive. The proposed plant would treat Kern River water and provide service to the areas in and adjacent to Section 1'7 plus provide a supplemental supply to existing City residents and Cai-Water customers. The total estimated cost for the preliminary engineering design is $25,000. The City's share of cost would not exceed $12,500. Staff requests Board approval to authorize the City to share the cost in the amount of $12,500 from the Agricultural Water fund. A motion for approval was made by Boardmember Sullivan. Motion carried. 6D. The attorney retainer agreement with Hatch & Parent to represent City in litigation was presented by Mr. Bogart. This agreement allows Hatch & Parent to represent the City in litigation matters as directed. There is no retainer involved and the billings will be on a hourly basis. The existing legal services agreement covers issues regarding general water matters and not litigation. A motion for approval was made by Boardmember Salvaggio. Motion carried. Board Chair Salvaggio asked that item 6C be reconsidered and Boardmember Smith made a motion to that effect. A motion was made by Boardmember Smith to approve the City's share of cost for the engineering design for the Northeast Water Supply Project as discussed in item 6C. Motion carried. 7. Meeting adjourned at 5:35pm.

The action giving rise to the ESA violations is the flooding of riparian habitat in the South Fork Wildlife Area and Kern River Preserve.through elevated water levels in Isabella Reservoir. The violations complained of are: (1) maintaining elevated water'levels in the Isabella Reservoir causing the inundation of the South Fork Wildlife Area and the Kern River Preserve during the consultation process in violation of section 7(d) of the Endangered Species Act, 16 U.S.C. § 1536(d), and (2) "taking" the southwestern willow flycatcher, including destroying its critical habitat, in violation of section 9(a) (1) (B) of the Endangered Species Act, 16 U.S.C. § 1538(a) (1) (B) . University of Denver-Foote Hall. 7150 Montview Boulevard. Denver, Colorado 80220. Telephone: 303-871-6996 · Fax: 303471-6991 atermaster 60-Day Notice Letter · October 1, 1997 Pa~e 2 Endangered Species Act (1) Section 7(a) (2) of the Endangered Species Act requires that each federal agency ensure that any activity it authorizes is not likely to jeopardize the continued existence of a threatened or endangered species. 16 U.S.C. § 1536(a) (2). Section 7(d) prohibits the federal agency and the permit or license applicant from making any irreversible or irretrievable commitment of resources which has the effect of foreclosing the formulation or implementation of alternative actions that would not cause jeopardy. 16 U.S.C. § 1536(d) The southwestern willow flycatcher is listed as'endangered under the Endangered Species Act and occurs in the South Fork Wildlife Area and the Kern River Preserve. With your assistance, the FWS and the Army Corps of Engineers have recently consulted regarding long-term operations of Isabella Reservoir and the impacts to the flycatcher. Maintaining elevated water levels in the Reservoir inundates riparian habitat along the shores of the Reservoir, destroying the flycatcher, its nests, eggs, and critical habitat. During this consultation process, you continued to insist that the Corps maintain elevated water levels in the Reservoir, ensuring that the riparian habitat would again be flooded during the growing season. Your action constitute an irreversible and irretrievable commitment of resources in violation of section 7(d). (2) Section 9ia)(1)(B) of the ESA prohibits the unlawful take of a listed Species. 16 U.S.C. § 1538(a)(1)(B). The FWS may exempt any person from this Prohibition through the proper issuance of an incidental take statement. 16 U.S.C. § 1536(o). The Watermaster is illegally taking the southwestern willow flycatcher in violation of section 9(a) (1) (B). First, although the FWS included an incidental take statement in its April 1997 biological opinion, the biological opinion was not validly issued. Because maintaining elevated water levels in the Reservoir jeopardizes the flycatcher, the incidental take statement fails to authorize taking this species and does not exempt the WatermaSter from the take prohibition. Second, even if the BO and take statement were legally issued, both the Corps, as the action agency, and the 'Watermaster 60-Day Notice Letter October 1, 1997 Page 3 WatermaSter are required to comply with the take statement's reasonable and prudent measures and terms and conditions as well as the "conservation measures" included in the Project Description. At this time, both you and the Corps have failed to perform the necessary mitigation measures. As a result, your are in violation of section 9's take prohibition concerning the southwestern willow flycatcher. We look forward to your prompt response to this letter.

The two completed phases and the currently out-to-bid third phase, have and will have been funded through the City's Domestic Water Enterprise from water sale revenues allocated to capital improvement projects and the collection of Availability Fees (connection fees) from developments requiring new water service. The City has invested $1,650,000 in the first two phases with the third phase engineer's estimate of $800,000, for a total commitment of $2,450,000. The Proposition 82 -1988 Water Conservation Bond Law loan will be used to complete the funding the fourth and last phase. Engineer's cost estimates for the 10 (ten) million gallon regulating/storage tank is $3,000,000.00 and this becomes the basis for the principal loan amount requested. The City has budgeted in its 1994-95 fiscal year budget for $1,050,000 to be combined with the loan request. This budgeted amount will be used to install main transmission pipes from the storage tank to the distribution system, telemetry modifications, engineering and inspection costs and contingencies. Loan re-payment is planned to be through a combination of savings resulting from use of off-peak electric power and reduced groundwater production charges. Additional re-payment funding will be from continued collection of Availability Fees on new water services and allocation from the capital improvement budget of the City Domestic Water Enterprise. EXAMPLE OF RE-PAYMENT: $3,00o,o00 loan amount 6.00% approximate interest rate 15 years term $310,000 estimated annual payment Annual Re-Payment to be composed of- $ 150,000 savings as a result of reduced groundwater pumping assessments 70,000 off-peak power used for pumping 40,000 Availability Fees collected from new development 50.000 Annual allocation from capital budget, diverted from construction of water wells $ 310,000 Total annual payment This phase (the Projec0 will be composed of the site preparation including excavation, soil testing and compaction needed to comply with construction requirements for the storage tank. The land is already owned in fee by the City of Bakersfield. The environmental studies and 'Conditional Use Permitn have already been processed and approved for the construction. The 10 million gallon storage tank will be constructed using a pre-stressed concrete method due to the versatility and the partial undergrounding of the tank. Dimensionally the tank will be approximately 200 feet in diameter and 38 feet tall, with about 19 feet above existing grade. The tank will be tied-in to a then existing booster station for distribution to the grid. The feed line for the tank will also be connected as part of this phase. Telemetry will be used to provide communication for well and tank level controls. The Supervisory Computer and Data Acquisition (SCADA) is to be fully installed with this phase to allow for overall control of the facility and compile production, distribution alarm system management for the site. Total estimated cost to be $4,050,000.00. A California registered civil engineer has been retained to prepare the final plans and specifications. The electrical control system is to be designed by a registered electrical engineer. 3). The estimated capital costs for the phase 4 (the Project) segment are composed of the total of the loan requested amount of $3,000,000.00 and City of Bakersfield Domestic Water Capital Improvement Project budget for 1994-95 in the amount of $1,050,000, for a $4,050,000 total as follows: Proposed Project Budget Summary: $ 100,000 site preparation, grading, soil testing and compaction 3,000,000 10 Million Gallon pre-stressed concrete storage tank @ $0.30/gallon 150,000 Pipeline link-up to distribution system 250,000 Engineering and inspection 100,000 Telemetry modification and SCADA system control installation 450.000 Contingency $4,050,000 Total Operating Costs Associated with Project The Project annual operating costs will be less than the alternative for producing and distributing water into the City's Domestic Water System. The alternative is to continue with the drilling and completion of groundwater production facilities within the City water service area, which also contributes to the overdrafting of the groundwater. The source of water supply for the Project, the City's '2800 Acres", has groundwater levels that are generally higher than within the service area. This will have the effect of ~ the costs to produce water. The ability to regulate the produced water into the storage tank will also reduce the City's pumping taxes and power costs (off-peak pumping). Please see attached City internal Memorandum on these potential cost savings. The tank will have a 50 year life, therefore the replacement costs less than the alternative for this Project which are groundwater wells. Replacement costs would be $60,000.00 per year. Project Benefits In addition, to the estimated economic advantages described, there will be an improvement in the water quality that will be made available to the residents and customers of the City Water System. The water quality in the "2800 Acres' is generally better than that what exists in the service area from which the present supply is derived. Historical water quality testing in the vicinity of the "2800 Acres' show that,. not only is water quality excellent for drinking water purposes, but is also relatively stable in quality. The completion of the Project will allow the introduction of new water to Bakersfield hereby reducing groundwater overdraft. Reducing overdraft provides a better groundwater supply in the form of shallower water levels than would exist without the Project. This will have an effect on the City wells that currently produce water for the system, with a reSUltant savings in the cost, to pump water.
