Authorize the Mayor to execute the contract and authorize the transfer of $105,935 from Water Fund Balance to the project account. DISCUSSION Background Several years ago, in conjunction with the development of the Airport Area Specific Plan, the City of San Luis Obispo initiated the development of a Water System MasterPlan (Master Plan). The Master Plan was prepared by Boyle Engineering Corporation through subcontract with Wallace, Roberts, and Todd (the lead consultant for the Airport Area Specific Plan). The overall purpose of the Master Plan was to evaluate the existing raw water delivery facilities, the water treatment plant, and the water distribution system to identify existing deficiencies and necessary improvements needed to meet both existing water service demands as well as those at full build- out as identified in the City's General Plan. The Master Plan identified the following improvements and studies to ensure reliable operation of the Water Treatment Plant to meet current and future city water demands. ■ Seismic evaluation of the existing water storage tanks ■ Addition of a second treated water storage tank(clearwell) ■ Upgrades to the transfer pump station • A new pipeline to serve the water treatment plant from Reservoir#2 • The need for an additional sedimentation basin On June 4, 2002, the City Council approved a request for proposals to provide engineering services associated with the recommended improvements and studies identified above. Three firms submitted proposals and Black and Veatch was selected as the top firm based on the experience of the project team and their understanding of the issues relative to this project. As Council may be aware, Black and Veatch were the project engineers for the Water Treatment Plant Upgrade Project that was completed in January of 1995. a ^� Council Agenda Report—Water System Master Plan Page 2 During the review of the proposals and discussions with Black and Veatch relative to the scope of work for the project, some additional issues and studies were identified which are also recommended as part of this contract. The additional work involves the evaluation of the Stenner Canyon Hydroelectric Facility, theoption to utilize a new sedimentation process which may eliminate the need to construct an additional sedimentation basin, a performance test of the Water Treatment Plant at full capacity (i.e. 16 mgd) and evaluation of the staffing needs for the water treatment plant under several operating scenarios. Work Scope The proposed scope of work as described in more detail in Exhibit A of Attachment 1 has been broken into three phases. The approval of this agreement with Black and Veatch is only for the work scope items identified as Phase 1, including the staffing evaluation (subtask 115). The Phase 1 work scope includes the following tasks which will provide the preliminary design report and initial environmental documentation. Task 100 Project Management Task 200 Water Treatment Plant Study and Preliminary Design Task 300 Geotechnical Services Task 400 Environmental Documentation Task 700 Stenner Canyon Hydroelectric Feasibility Study The preliminary design report will thoroughly evaluate the recommended improvements identified in the Water System Master Plan for the Water Treatment Plant. The geotechnical work associated with siting the new clearwell as well as information needed for the seismic evaluation of the existing onsite water storage tanks will also be included in the preliminary report. Relative to the recommended onsite improvements, a screen check initial environmental survey will be completed and submitted to the City for review and comment. In addition, an analysis for the potential to utilize the available flows in the Salinas Reservoir raw water delivery pipeline to generate electrical energy will be further evaluated as discussed in the next section. Hydroelectric Plant While the existing hydroelectric plant has been studied by several consultants who have expertise in energy production projects, the consultants were unable to adequately address concerns relative to potential impacts to the water treatment plant operations. Due to the changes associated with the upgrade to the water treatment in 1995, which modified the treatment process to utilize ozone as the primary disinfectant, there are potential problems that could jeopardize the City's ability to ensure safe, dependable water treatment if the existing hydroelectric plant was placed back in service: To ensure that the water treatment impacts are properly addressed, staff recommends that the evaluation of the opportunities for harnessing this potential energy supply a-a- Council Agenda Report—Water System Master Plan Page 3 be evaluated by Black and Veatch as part of this contract. Black and Veatch have recently completed several similar projects that have coordinated energy production from a raw water delivery pipeline with the operation of the water treatment plant. Black and Veatch's understanding of the operational constraints associated with the water treatment plant, coupled with their in-house expertise with hydroelectric facilities, will provide the ability to properly address the issues and concerns posed by staff. Following completion of Phase 1, the recommendations for improvements needed to ensure reliable operations and ability to meet water quality regulations into the future will be presented to Council for review. Based on the direction provided by the City Council, the Phase 2 scope of services will be refined for the preparation of the final plans and specifications for the recommended improvements. The phased approach is recommended since the work scope can not be accurately defined for subsequent phases until the preliminary studies are completed. Depending on the recommended improvements identified in the preliminary design report, the costs for preparation of the final plans and specifications will be revised to reflect the level of consultant effort needed. Summary The implementation of the recommended improvements identified in the Water System Master Plan will ensure that the City's Water Treatment Plant will continue to provide safe and reliable water supplies to meet the City's demands well into the future. FISCAL IMPACT The Water Treatment Plant Master Plan Implementation Project was identified in the 2001-03 Financial Plan, Appendix B, Page 110-112. The financial plan request estimated $125,000 for study and design. The cost associated with the contract with Black and Veatch for Phase 1 of the project is $230,935. An additional $105,935 will need to be appropriated from Water Fund Balance to support the Phase 1 contract. To cover this, as well as minor costs (printing, etc.) associated with this project, $107,000 is recommended to be transferred from Water Fund working capital. There is sufficient available working capital in the Water Fund to fund the contract and still meet minimum reserve policy levels. Black and Veatch have Table I Master Plan Project: Estimated Costs provided preliminary Phase 1: Preliminary Studies &Desi $230,935 estimates for the current and Phase 2: Final Desi $197,567 subsequent phases of the phase 3: Construction Administration $209,731 project, as well as Subtotal: Design&Administration $6383,233 construction costs, are shown in Table 1. Phase 2 will I Project Construction $4- 7m* ion involve preparation of the final plans and specifications as well as the draft initial environmental assessment. Phase 3 costs are for construction administration services but do not include onsite resident engineer services. a - 3 Council Agenda Report—Water System Master Plan Page 4 ALTERNATIVES 1. Defer the Analysis and Studies: This alternative is not recommended for a number of reasons. Deferral of seismic analysis of the existing tanks may jeopardize the City's ability to provide treated water to residents following a seismic event. In addition, the existing clearwell tank is in need of repairs and recoating to ensure ongoing service capabilities. This tank is critical to the operations of the treatment plant and can not be taken out of service until a new tank is constructed and available for use. 2. Modify Work Scope: Staff believes that the work scope as currently defined will provide the analysis and information needed to ensure that the City can meet water quality standards into the future and provide reliable water service to the community. Staff recommends the project work scope, however staff is prepared to discuss any scoping changes Council may desire and incorporate those changes into the agreement. ATTACHMENT: 1.

Task 300 - WTP Geotechnical Investigation and Evaluation Geomatrix, as a subconsultant to Black & Veatch, will perform the geotechnical investigation and evaluation services for the Project. Subtask 305. Provide Geotechnical Consultation and Attend Meetings (Phase I) Conduct periodic telephone conversations and informal discussions with the City as work progresses. Geomatrix has assumed that their attendance will be required at 2 progress meetings. Subtask 310. Compile and Review Information (Phase I) Review published and unpublished information, reports, and drawings relevant to geologic and geotechnical conditions at the subject site.. Review available aerial photographs of the project vicinity for features or conditions that may affect the design of the project. Subtask.315. Field Exploration/Mapping (Phase I) Geologic and subsurface conditions at the new and existing clearwell sites, the wash water tank site, and along the proposed connecting pipeline alignment will be explored using the following techniques. • Geologic mapping will be performed to examine surface geologic conditions or features that may affect the proposed locations or designs of facilities. • Borings will be drilled to explore subsurface conditions at the 2 clearwell sites, and the wash water tank site. As many as 7 borings (approximately 20 to 30 feet deep) will be drilled to explore conditions at the existing and new clearwell sites and the wash water tank site. The ata borings will be drilled using rotary wash techniques to obtain high quality samples of soil and rock for laboratory testing. Borings will be terminated at least 10 feet into bedrock. One boring at the new clearwell site will be converted into a piezometer to measure groundwater levels. It is assumed that access to the site will be provided by the City. It is also assumed there are no unusual permitting requirements for performing the exploratory work and the drilling sites can be accessed with truck-mounted drilling rigs. The borings not converted into piezometers will be backfilled with cement grout. Drilling fluids/cuttings will be spread over the ground surface near each borehole site or taken to an on-site disposal area. Locations of the exploration points will be staked and/or otherwise marked in the field for later identification and surveying. Subtask 320. Conduct Laboratory Testing(Phase I) Laboratory tests will be performed on selected samples of the soils and rock encountered in the borings. The types and numbers of tests proposed herein represent our best estimate of the level of effort that may be required to evaluate the character and geotechnical properties of the natural soils and rock and the usefulness of the soils for site fill and backfill. The actual number of tests that will be performed may differ depending on the findings of the field exploration program. It is anticipated that the following tests will be performed: • Visual classification(all samples). • Atterberg limits (3 tests). • Grain size distribution (4 tests). • Moisture content and dry density(14 tests). • Moisture-density relations(compaction test- 1 test). • Unconfined compression or direct shear(4 tests). • Consolidation(2 tests). Subtask 325. Perform Engineering Analyses and Evaluations (Phase I) Perform engineering analyses and evaluations to develop recommendations and geotechnical parameters for final design of (1) the new clearwell, (2) retrofit of the existing clearwell and wash water tank, and (3) the new connecting pipelines (pipeline evaluations will be based on the findings from exploratory work at tank sites). Analyses and evaluations will include: • Anticipated soil/rock conditions. • Anticipated groundwater conditions. • Site preparation (ground modification or improvement). • Excavation conditions. • Fill and backfill materials,compaction,and methods of placement. • Drainage requirements beneath and adjacent to structures and fills. • Methods to resist uplift forces,if appropriate. • Suitable foundation types: - Spread and strip-type footings • Geotechnical design parameters: a- 13 - Allowable bearing pressures. • Amount of settlement and methods for reducing same. • Discussions concerning the mitigation of specific geologic/geotechnical hazards. • Design of pipelines: - Pipe zone bedding and backfill requirements (materials and compaction). - Trench zone and final backfill. - Unit weight of backfill. - Rankine's lateral pressure ratio times the coefficient of friction of backfill. - Modulus of soil reaction. - Coefficient of friction between pipe and backfill. - Cohesiveness. • Seismic design parameters (i.e., based on the 1997 Uniform Building Code [UBC]). Subtask 330. Prepare Geologic/Geotechnical Report(Phase II) Prepare a formal report that includes findings frorn the previous subtask and summarizes all design recommendations. In addition to the text, the report will contain geologic maps, maps showing the locations of exploration points, profiles and cross sections showing soil types, logs of borings, results of laboratory and field tests, and other supporting data. The final report will include text, tables, and graphs that present the geotechnical information pertinent to design of the project. Deliverables: Geologic/Geotechnical Report (5 copies of draft and final). Subtask 335. Geotechnical Review of Plans and Specifications (Phase II) Review the geotechnical aspects of the 90% Design plans and specifications. Review comments will be summarized in a letter and/or on copies of drawings and will outline discrepancies that may exist between the contract documents and the geotechnical report. Task 400-WTI?Environmental Documentation-Phase I & II ESA, as a subconsultant to Black & Veatch, will prepare the environmental documentation for the Project in accordance with the California Environmental Quality Act(CEQA) and State CEQA Guidelines. Subtask 405. Meetings and Consultation (Phase I) Conduct periodic telephone conversations and informal discussions with the City as work progresses. ESA has assumed that their attendance will be, required at 3 progress meetings. Subtask 410. Screencheck Initial Survey (Phase I) Prepare an Initial Study to identify issues that could potentially cause significant impacts. Review existing reports relating to the project site and surrounding.areas including previous CEQA compliance documents, site assessments, and preliminary design reports. The Initial Study will assess the potential impacts resulting from the construction and operation of the proposed treatment and storage facilities on water quality, air quality, aesthetics, public hazards, recreation; population and housing, traffic; noise, land use, biological resources, cultural resources, geology, public services, and utilities. Much of the analysis will focus on construction impacts such as biology, cultural resources, air emissions, noise, and storm water control. Operational/long-term effects will also be assessed including the aesthetic effects of the proposed facility on the local viewshed. It is assumed that the analysis would not include an assessment of the project's potential to induce growth or evaluate secondary effects of growth, since these issues are covered in the City's General Plan. The project will be evaluated for consistency with the City's General Plan. Once site plans and elevations are obtained, ESA will visit the WTP and evaluate the potential for the proposed clearwell to adversely affect sensitive views (e.g., views of scenic resources from publicly accessible vantage points, such as parks and recreation areas). The Initial Study analysis will include photo-documentation, as appropriate. The evaluation will reflect existing visual conditions of the WTP site and surrounding area. It is not anticipated that visual simulations will be needed(see Optional Task 425). Perform a reconnaissance level biological survey of the site, and prepare an assessment of . potential endangered species and sensitive habitat that could be affected by the project. If warranted, conduct an informal consultation with California Department of Fish and Game staff to evaluate appropriate mitigation measures. Conduct a cultural records search for known archaeological sites in the project area. The results of the search will be summarized in the Initial Study. It is assumed that the property does not include structures that would be eligible for the National Register of Historic Places. Conduct a Phase I Cultural Resources Survey of the project site and prepare a report of the survey. As necessary, mitigation measures will be identified to reduce potential environmental effects of the project. To assist in compliance with CEQA and facilitate adoption of any conditions of approval, prepare mitigation measures within the Initial Study identifying specific standards where possible. Submit 5 copies of the draft Initial Study to the City for review and comment. Subtask 415. Prepare Draft Initial Study/Mitigated Negative Declaration (Phase II) Following review by the City of the Initial Study, incorporate the necessary revisions into the document. Assuming the Initial Study does not identify potentially significant impacts that cannot be mitigated, produce and deliver 5 copies of the Initial Study/Mitigated Negative Declaration to the City for publication and public review. It is assumed the City will compile the mailing list and will mail the documents. (These services can be provided at additional cost.) It is assumed that no public hearings will be conducted for the project. Subtask 420. Prepare Response to Comments (Phase II) Meet with City staff to receive and review public comments on the Initial Study/ Mitigated Negative Declaration. Prepare written responses to public comments. In addition, a written narrative of all received comments will be prepared for inclusion in the Draft Response to Comments. Submit the draft Response to Comments/Final Mitigated Negative Declaration document to the City for review and comments. Incorporate the City's comments and submit 5 copiesof the Final Response to Continents Initial Study / Mitigated Negative Declaration to the City for consideration by the City Council. Deliverables: 5 copies of Final Response to Comments Initial Study/Mitigated Declaration. Subtask 425. Preparation of Environmental Impact Report and Visual Simulations — Optional Task In the event the Initial Study identifies potentially significant impacts that cannot be avoided through mitigation, prepare a focused Environmental Impact Report (EIR) assessing those issues that the Initial Study identified as potentially significant. To initiate the EIR process, prepare a draft Notice of Preparation (NOP) pursuant to CEQA requirements. Incorporate the comments from the City and Black& Veatch, and prepare a final NOP for submittal to interested agencies. Attend a scoping meeting to solicit comments from interested parties. The NOP will circulate for 30 days. Prepare an administrative Draft Focused EIR for submittal to the City. Incorporate City comments and will submit 5 copies of the Draft Focused EIR to the City for public circulation with visual simulations to depict the visual impact of the proposed facilities from several vantage points. It is assumed the City will compile the mailing list, make multiple copies of the document, mail the documents, and post public notices as required by CEQA. ESA will be available to assist as necessary. Attend a public hearing on the Draft Focused EIR, and prepare responses to comments for inclusion in the Final Focused EIR. Incorporate the City's comments into the Final Focused EIR, and submit 5 copies to the City for consideration by the City Council.
