13 WATER SAVINGS PERFORMANCE Why Are We Giving Back Our Savings? Irrigation exceeds Evapotranspiration (ET) in fall. ET is the amount of water lost by plants & soil. It s essentially rain in reverse!

16 RATE RESTRUCTURE & WATER BUDGET

17 RATE RESTRUCTURE & WATER BUDGET Re-Balancing Fixed & Variable Cost Recovery GOAL: Fixed charges recovers 100% of fixed costs Protects District & Customers from rate volatility Variable Charges tied to efficient water use NEW: Budget-Based Tiered Rates

18 OUTDOOR WATER BUDGET The Right Amount of Water for Your Landscape. No More. No Less. Water Budgets provide the water your landscape needs you decide how and where to use it.

19 ET (inches) OUTDOOR WATER BUDGET EVAPOTRANSPIRATION (ET) RAIN IN REVERSE ET measures water lost in inches per square foot California Irrigation Management Information System (CIMIS) provides real-time 24/7 weather data Station #241, Talega (San Clemente) Station #245, Coto de Caza Measuring ET Historical Monthly ET (inches) Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec

20 OUTDOOR WATER BUDGET IRRIGABLE AREA Budget based on area irrigated per meter. Fair Water Budget ET determines water needed per square foot of irrigable area. High-resolution aerial imager & GIS analysis to determine vegetation classifications by square footage.

21 OUTDOOR WATER BUDGET CONVERSION FACTORS 0.8 ET Adjustment Factor Adjusts ET to reflect a medium plant mix (50% ET) Provides extra water for sprinkler system inefficiency (62.3% efficiency) 0.8 = 0.5/ ,200 = Conversion Factor to CCF Converts inches per sq.ft. to CCF 1 CCF = 1 Billing Unit = 748 Gallons
