SUBJECT
Urban Water Management Plan and Water Shortage Contingency Plan: Review and Adopt the 2020 Urban Water Management and 2020 Water Shortage Contingency Plans
RECOMMENDATION
That the City Council adopts two resolutions (Attachment II and Attachment III) approving the 2020 Urban Water Management Plan (UWMP) and the 2020 Water Shortage Contingency Plan (WSCP).
SUMMARY
All water agencies in California that deliver at least 3,000-acre feet of water each year and have 3,000 or more service connections, including Hayward, are required to prepare an UWMP and WSCP every five years. The 2020 UWMP outlines the City's water demands through 2040 to evaluate and develop a plan to ensure sufficient supplies for residents and businesses. Because Hayward relies exclusively on the San Francisco Public Utilities Commission (SFPUC) Regional Water System for potable water supply, available supplies from that source are critical to the City's planning. The WSCP provides guidance for managing water supply shortages in a proactive and methodical way.
The City worked with the Bay Area Water Supply and Conservation Agency (BAWSCA) to develop water demand projections using a consistent methodology. Water supply availability information was provided by SFPUC. In 2020, the SFPUC has incorporated certain flow assumptions based on the State Water Resources Control Board's Plan for the San Francisco Bay/Sacramento-San Joaquin Delta Estuary (known as the Bay-Delta Plan). These assumptions significantly limit supplies in the event of a multiple-year drought, as documented in the UWMP and discussed in this report.
Although the WSCP is appended to the UWMP, staff recommends that the two documents be adopted separately so that Council has the ability to amend the WSCP as needed to meet supply conditions without amending the UWMP.
