RECOMMENDATION: Recommendation
Receive update and discuss the water conservation program savings number for Fiscal Year 2025.
Body
SUMMARY:
Since 1992, Valley Water's robust Water Conservation Program (Program) has supported the Board of Directors (Board's) long-term water conservation savings goals established through the Water Supply Master Plans (WSMPs) 2040 and 2050, which include annual monitoring. The Program also supports Board Resolution 23-52 to Make Water Conservation a Way of Life in Santa Clara County. The nearest milestone is to conserve 99,000 acre-feet per year (AFY) by 2030 (compared to the 1992 baseline).
Valley Water staff tracks progress towards the long-term conservation goals using a custom, Excel-based Water Conservation Savings Model1 (Savings Model). Every year, staff inputs annual Program participation totals from the prior fiscal year into the Savings Model to track progress toward the long-term conservation goals. To leverage the latest data available, staff periodically update model assumptions such as program water savings, savings accrual rates, and population and housing data, which can affect the prior year's reported savings. Details on the Savings Model's inputs and program assumptions are in Attachment 2. This memo provides an update on fiscal year (FY) 2025 savings and reviews program trends.
Information about current conservation programs is detailed in the attached flyer and can be found at www.watersavings.org (Attachment 3).
