feasible or had more significant costs and lower benefits relative to the PFAS Treatment and Well Rehabilitation Project. Alternatives (or combinations of other options that can produce 3,500-acre feet/year) that passed the initial screening were evaluated in further detail based on the criteria developed. 4. Alternatives Evaluation COMPLETED BC refined the evaluation criteria based on feedback from the Ad Hoc Subcommittee and confirmed the requirements with the Ad Hoc Subcommittee in January 2023. BC worked with the Ad Hoc Subcommittee to assign relative weights to the criteria and develop a scoring rubric for the alternatives. Task 4 focused on a deeper technical analysis of the alternatives (e.g., groundwater modeling to estimate long-term yield and water quality and coordination with the City's hydraulic model to estimate the ability to distribute future maximum day demands) to further scope the alternatives, scored them against the evaluation criteria, and prepared preliminary cost estimates. BC then prioritized the alternatives, and the preferred option was recommended. 5. Recommendations and Report COMPLETED BC will present potential project delivery models for design, construction, operation and maintenance, financing, and ownership of the preferred alternative from Task 4 and make a recommendation. BC will prepare draft and final reports summarizing the work performed, presenting the results of the alternatives evaluation, and including an implementation plan for the preferred alternative that includes the recommended project delivery model, significant tasks, and milestone schedule. 6. Council Meetings and Engagement IN PROGRESS BC to attend monthly Ad Hoc Subcommittee meetings and coordinate with City Staff to prepare for meetings, including preparation of slides. BC to attend City Council meetings quarterly and coordinate with City Staff to prepare for meetings, including the development of slides. This task also includes supporting relevant public engagement efforts, such as addressing public comments and questions raised during Ad Hoc Subcommittee or City Council meetings, as appropriate. CONCLUSION Based on the analysis provided in the discussion above, Staff recommends the City Council take several actions, including • Accept the Water Supply Alternatives Study Draft Final Report October 12, 2023 • Approve proceeding with planning and developing two new wells as the preferred water supply alternative, including evaluating a joint project with Zone 7 Water Agency • Establish a new Capital Improvement Project— Two New City Wells (Wells 9 & 10 and Associated Pipelines) CIP No. 24174 Page 7 of 8
