City Council Staff Report From: City Manager Report Type: CONSENT CALENDAR Lead Department: Utilities Meeting Date: June 9, 2025 Report #:2504-4515 TITLE 2025 Annual Water Supply and Demand CEQA Status Assessment -- Exempt under Water Code Section 10652. RECOMMENDATION Staff and the Utilities Advisory Commission (UAC) recommend City Council adopt the 2025 Annual Water Shortage Assessment Report. BACKGROUND Beginning in 2022, every urban water supplier in California must conduct an Annual Water Supply and Demand Assessment as required by California Water Code Section 10632(a). Each urban water supplier must also submit an Annual Water Shortage Assessment Report to the Department of Water Resources (DWR) on or before July 1, as required by California Water Code Section 10632.1. The City’s Annual Water Shortage Assessment Report (Attachment A, Tables 1- 5) shows that there is no water shortage anticipated for Fiscal Year 2026. On April 15, 2025, the San Francisco Public Utilities Commission (SFPUC), Palo Alto’s water supplier, provided Palo Alto with the Water Supply Availability Update indicating for the current water year, Hetch Hetchy watershed has experienced nearly average conditions for precipitation and snowpack. The City of Palo Alto encourages continued water conservation efforts and the City’s website contains more information about available water conservation programs.1 DUSCUSSION To prepare the 2025 Annual Water Shortage Assessment Report, staff followed the procedures outlined in its Water Shortage Contingency Plan, contained in Section 7 of the City’s 2020 Urban Water Management Plan (UWMP).2 Palo Alto’s 2025 Annual Water Shortage Assessment Report uses the DWR-developed Optional Annual Assessment Tool format. This format includes the 5 tables shown in Attachment A. Staff will submit the standard tables to DWR by July 1, 2025. “Table 1. Annual Assessment Information” (Table 1) provides required overview information.

Potable Water •“Table 2: Water Demands” (Table 2) provides a demand projection for each month of FY 2026; •“Table 3: Water Supplies” (Table 3) notes that there is sufficient supply to meet Palo Alto’s demand and projects supply equal to the demand projection since there is no projected water shortage in FY 2026; •“Table 4(P): Potable Water Shortage Assessment” (Table 4(P)) compares projected FY 2025 demand with supply and illustrates that there is no shortage projected for FY 2026; •“Table 5: Planned Water Shortage Response Actions” (Table 5) shows no triggered water shortage actions.
