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