A This chapter describes the preparation of the City's 2020 UWMP and WSCP, including the basis for the preparation of the plan, individual or regional planning, fiscal or calendaryear reporting, units of measure, and plan coordination and outreach. 2.1 BASIS FOR PREPARING A PLAN The Act requires every "urban water supplier" to prepare and adopt a UWMP, to periodically (at least once every five years) review its UWMP, and make any amendments or changes that are indicated by the review. An "urban water supplier" is defined as a supplier, either publicly or privately owned, providing water for municipal purposes either directly or indirectly to more than 3,000 customers or supplying more than 3,000 acre-feet of water annually (AFY). The City is a water retailer and manages Water System CA0110008. As shown in Table 2-1, in 2020, the City provided water to 22,369 customer connections and supplied 14,779 acre-feet (AF) of water. Therefore, the City is required to prepare a UWMP. The City's last UWMP, the 2015 UWMP, was adopted by the City Council on June 7, 2016. Table 2-1. Public Water Systems (DWR Table 2-1 Retail) Public Water System Public Water System Number of Municipal Volume of Number Name Connections 2020 Water Supplied 2020 * CA0110008 City of Pleasanton 22,369 14,779 TOTAL 22,369 14,779 * Units of measure (AF, CCF, MG) must remain consistent throughout the UWMP as reported in Table 2-3. NOTES: Volumes are in acre-feet (AF); number of connections and volume of water supplied is for potable water system only. 2.2 REGIONAL PLANNING As described in Section 2.3 below, the City has prepared this 2020 UWMP on an individual reporting basis, not part of a regional planning process. However, the City regularly coordinates with its water wholesaler, Zone 7, to ensure that a safe and reliable water supply is delivered to its existing customers and that plans for serving future customers are implemented as efficiently as possible. The City also routinely coordinates with the region's other water retailers—DSRSD, Livermore, and Cal Water—on water supply and water conservation matters, including preparation of Zone 7's 2019 Water Supply Evaluation (WSE), 2020 UWMP, and WSCP update. Additionally, the City coordinates with the San Francisco Public Utilities Commission, which supplies water to the unincorporated Castlewood area and the Town of Sunol, which are adjacent to the City. Zone 7 also assisted the City in the preparation of this UWMP. WEST YOST 2-1 City of Pleasanton 2020 Urban Water Management Plan May 2021
