ITEM NO. 10 <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br />ORIGINATING SECTION: Water Supply Engineering <br />CONTACT: Elliott Levitsky/Brandon Woods <br /> <br />AGENDA DATE: August 19, 2026 <br /> <br />SUBJECT: Award a Contract for Preliminary Design and Owner's Representative Services for <br />the Regional Groundwater Development Project <br /> <br />SUMMARY: <br /> <br />• The proposed action supports Strategic Plan Goal B – Reliable Water Supply and <br />Infrastructure; Goal C – Safe Water; and Goal D – Groundwater Management; and <br />supports Initiative 5 – Develop a diversified water supply plan and implement supported <br />projects and programs; Initiative 6 – Continue to Effectively Implement Infrastructure <br />Projects in the Water System Capital Improvement Plan; and Initiative 11 – Manage the <br />Groundwater Sustainability Agency and implement the Groundwater Sustainability Plan. <br /> <br />• Zone 7 identified exploring the Bernal subbasin as an opportunity to increase groundwater <br />production capacity to meet projected future demands. The City of Pleasanton (City) <br />selected installation of new wells in the Bernal subbasin as the preferred option to replace <br />the Groundwater Pumping Quota it lost when its three wells were removed from service <br />due to per- and polyfluoroalkyl substances (PFAS). A joint feasibility study and the basis of <br />design report were completed to evaluate synergies of a joint project to meet these <br />objectives. <br /> <br />• The study confirmed that a joint project enables both agencies to achieve significant cost <br />savings through economies of scale, minimize impacts to the community and environment, <br />and gain long-term operational efficiencies. On May 20, 2026, the Zone 7 Board authorized <br />an agreement with the City for Zone 7 to implement the project, further described below. <br />The City Council plans to consider approval of the agreement on September 1, 2026. <br /> <br />• As the lead agency, Zone 7 plans to deliver the Project using the Progressive Design-Build <br />(PDB) contracting, a collaborative delivery approach that combines design and construction <br />under a single contract. PDB was selected to reduce the overall project schedule and <br />reduce project risks. In particular, early electrical design and equipment procurement are <br />intended to accelerate critical-path activities, including PG&E coordination, to meet the <br />Project's target operational date of December 2029. <br /> <br />Attachment 1 <br />Page 131 of 318
