Page 6 of 9 Rev. 11/23 EXHIBIT A – SCOPE OF WORK Background Akel Engineering Group, Inc. (Akel) prepared the 2024 Water Distribution System Capacity Master Plan (WDSCMP) for the City of Pleasanton (City). The WDSCMP evaluated the City’s water distribution system and recommended improvements necessary to service the needs of existing users and future development. Table 8.2 of the WDSCMP provides a summary of the recommended improvements. The City’s water supply comes from two sources: (1) wholesale purchases from Zone 7 that is delivered to the City’s water distribution system through seven turnouts; and (2) City’s groundwater production quota (GPQ) of 3,500 AF/year that is delivered within the City’s water distribution system via connections to City owned Wells 5, 6, and 8. The City currently has lost the ability to utilize its GPQ since Wells 5, 6, and 8 are not operational due to the presence of PFAS concentrations. The City is pursuing both near-term and long-term solutions to offset the loss of its GPQ, which require improvements to the water distribution system to properly implement. The 2024 WDSCMP included assumptions and recommendations on water supply change as described below: 1. Near-Term Improvements for Water Supply Change This solution is for the near-term replacement of Wells 5, 6, and 8 by purchasing one hundred percent of its water supply from Zone 7 that is delivered through the seven turnouts. This solution requires the following water distribution improvements as recommended in the WDSCMP: a. S-1. Construct 3,250 feet of 24-inch pipeline (the existing 12-inch to be abandoned) in Stoneridge Road between Hopyard Road and Johnson Drive. b. S-2. Construct 1,600 feet of 18-inch pipeline in Bernal Avenue between Nevada Court and Vineyard Avenue. c. S-3. Construct 4,650 feet of 20-inch pipeline in Sunol Boulevard between Bernal Avenue and Sycamore Road. d. BS-1. Booster Station at Turnout 4 at Hopyard Road and Stoneridge Drive with a firm capacity of 5,200 gallons per minute. The projects to implement the above are also picking up the following existing pipeline deficiencies identified in the WDSCMP due to their proximity: e. I-2. Construct 160 feet of 18-inch pipeline in Stoneridge Drive from Turnout #4 to Hopyard Road f. I-3. Replace 210 feet of existing 10-inch pipeline with a new 16-inch pipeline in Vineyard Avenue between the Vineyard Booster Station and Bernal Avenue. The projects are currently in the construction phase. 2. Long-Term Improvements for Water Supply Change This solution is for the long-term replacement of Wells 5, 6, and 8 and includes a new 3,000 gpm well at Bernal Park and a new 3,000 gpm well at Del Prado Park. This solution requires the following water distribution improvements as recommended in the WDSCMP: Docusign Envelope ID: E67CB798-34D0-4A4E-BFB8-E9718C48E0D9
