2 What is the UWMP•UWMPs are required by the California Water Code (CWC)•Long-range water planning document evaluating water supply and demand through 2050•Planning tool to ensure adequate availability and reliability of water supplies to meet current and projected future demands•Serves as a foundational document for Water Supply Assessments for proposed development projects (as required by SB 610 and SB 221)3 The 2025 UWMP is due to the California Department of Water Resources (DWR) byJuly 1, 2026 UWMP vs Water Master Plan•The City is also preparing an update to its Water Master Plan (WMP)•WMP evaluates the capacity of existing system facilities to meet current and future demands •It also outlines the capital improvement program designed to support the needed system improvements4 3 4
3 Why is an UWMP Required?•UWMP Act –AB 797 enacted in 1983, California Water Code Section 10610-10657–Applies to urban water suppliers serving more than 3,000 customers or 3,000 acre-feet/year (AFY) of supply–Required to be updated every 5 years–Required to remain eligible for California State grants and loans1 acre-foot of water= 325,829 gallons5 Why is an UWMP Required?•In 2025, the City served approximately 25,875 connections and delivered 16,857 acre-feet of potable water and 3,871 acre-feet of recycled water to customers•The City’s 2020 UWMP was adopted in June 2021e 20216 5 6
4 UWMP Key Components•2025 UWMP has been prepared based on the guidance provided by DWR and includes the following key chapters:–System Description (Chapter 3)–Water Demand Projections (Chapter 4)–Conservation Target Compliance (SB X7-7) (Chapter 5)–Water Supply Availability and Reliability (Chapters 6 & 7)–Water Shortage Contingency Plan (Chapter 8 and Appendix G)–Demand Management Measures (Chapter 9) 7 Current Water Supplies•Potable Water Supplies–Purchases from San Francisco Public Utilities Commission (SFPUC) – 16%–Purchases from Valley Water – 12%–Groundwater pumped from City-owned wells –53%•Non-Potable Supplies:–Recycled Water from South Bay Water Recycling (SBWR) – 19% 8 7

Future Water Supply Availability & Reliability•SFPUC Supplies–Future supply projections are based on two scenarios:•Without Bay-Delta Plan Amendments – no reduction in supply availability for the City in dry years•With Bay-Delta Plan Amendments – up to 48% reduction in supply availability for the City in dry years (represents worst case). This represents a reduction in the total City supplies by approximately 7.5%.–Agreements to Support Healthy Rivers and Landscapes are pending and are not included in SFPUC 2025 UWMP or the City’s 2025 UWMP9 Future Water Supply Availability & Reliability•Valley Water Supplies–Valley Water’s surface water supplies and imported water supplies may have reduced availability in dry years, but is supplemented with groundwater recharge and supplies from local storage–City anticipates up to a 5% reduction in supplies in some dry years. This represents a reduction in total City supplies by approximately 0.6%•Groundwater Supplies–Projected to be reliable for future dry years•Recycled Water Supplies–Projected to be reliable for future dry years10 9 10
6 Key Findings•Although supplies from SFPUC and Valley Water may be reduced in dry years, the City:–Is projected to have adequate water supplies to meet projected demands under all hydrologic year types (normal, single dry and multiple dry years) through the Year 2050–Will supplement any reductions in supplies from SFPUC or Valley Water by offsetting with increased groundwater pumping11 Key Findings•The City’s Water Shortage Contingency Plan outlines actions to be taken in the event of a water shortage–The WSCP describes 6 standard stages for water shortages up to 50% and greater along with proposed actions at each stage to address supply shortages –The WSCP also outlines the procedure for the City’s Annual Water Supply and Demand Assessment (AWSDA) which is required to be submitted to DWR annually on July 1Percent Shortage RangeStandard Shortage LevelsUp to 10%1Up to 20%2Up to 30%3Up to 40%4Up to 50%5>50%612 11 12
7 Key Findings•City’s Water Conservation Program supports the efficient use and conservation of water resources–Permanent water use restrictions reduce water waste–Public education and outreach programs in coordination with Valley Water–Water surveys and rebate programs to assist water customers with water use efficiency improvements 13 Recommendations•Staff recommends that the Council approve and adopt the 2025 Urban Water Management Plan and 2025 Water Shortage Contingency Plan.14 13 14
