City of Pleasanton | Water Shortage Contingency Plan <br /> Public Draft | May 2026 <br /> 3 EKI Environment & Water, Inc. <br />• Salts, nutrients, or contaminants in the groundwater basin. <br />2 ANNUAL WATER SUPPLY AND DEMAND ASSESSMENT PROCEDURES <br />Beginning July 1, 2022, CWC §10632.1 requires water suppliers to submit an Annual Water Supply and <br />Demand Assessment (AWSDA) and an Annual Water Shortage Assessment Report to DWR. The AWSDA is <br />used to evaluate near-term water supply reliability for the upcoming fiscal year so that the City can <br />prepare logistically and financially for any anticipated water supply constraints, as well as enact <br />appropriate shortage response actions in a timely manner. <br />This section provides the procedures for the City to conduct its AWSDA, which will inform the City’s Annual <br />Water Shortage Assessment Report and assist the City with planning for potential water supply shortages, <br />including details of the decision-making process, key data inputs, and the steps the City may take to <br />declare a water shortage emergency based on the level of shortage (Section 3) and implement water <br />shortage response actions (Section 4). Given the City’s reliance on water from Zone 7, the City develops <br />its AWSDA using Zone 7’s “Annual Review of the Sustainable Water Supply Report” (Annual Sustainability <br />Report). <br />2.1 Decision-Making Process <br />To consistently produce its AWSDA, the City uses the decision-making process described in this section <br />and may adjust and improve the process as needed. <br />The City’s Projection Team, consisting of the Utilities Planning Manager and the Assistant Director of <br />Environmental Services and Utilities, is responsible for preparing/approving the City’s AWSDA and Annual <br />Water Shortage Assessment Report and submitting them to DWR by July 1st of each year. Staff gathers <br />key data inputs and conducts the assessment in accordance with Section 2.2. In April, the Projection Team <br />finalizes the assessment based on Zone 7’s Annual Sustainability Report. The AWSDA and Annual Water <br />Shortage Assessment Report is presented to the Assistant Director of Utilities and Environmental Services, <br />or designee, for review and approval. If the AWSDA concludes that available water supply is sufficient to <br />meet expected demands for the current year and one subsequent dry year, no further action is required. <br />To conduct the AWSDA and prepare the Annual Water Shortage Assessment Report, the Projection Team <br />follows the schedule of activities shown in Table 1. Due to year-to-year variations in hydrologic conditions, <br />the timeframes shown in the tables are approximate and may be adjusted as needed. The City intends to <br />implement shortage response actions to effectively address anticipated water shortage conditions in a <br />timely manner while complying with the State’s reporting requirements. <br />Table 1.
