WHAT IF THE TREND DOES NOT CHANGE?

(amends 2015) 25% reduction through February 2016 (extended to October 2016) Prohibited actions: no irrigation runoff, use shut-off nozzle, no spraying walkways, recirculate fountains, no irrigation within 48 hours of rain, etc. Mandatory actions: conservation standards based on per capita water usage (8% minimum), monthly reporting Additional conservation tools (enforcement): additional actions, fines, etc. Extends emergency water conservation through January 2017 Prohibited actions: no irrigation runoff, use shut-off nozzle, no spraying walkways, recirculate fountains, no irrigation within 48 hours of rain, etc. Mandatory actions: conservation standards based on per capita water usage (8% minimum), monthly reporting OR Self-certification of supply reliability for three additional years of drought like 2013 – Wholesale supplies due 6/15/16 Self-certifications due 6/22/16 Additional conservation tools (enforcement): additional actions, fines, etc.

STEP 1: Determine Annual Total Potable Water Demand Production in 2013 Production in 2014 Calculated annual potable demand = Average 2013 and 2014 STEP 2: Estimate Annual [Available] Total Potable Water Supply 2017 – 2019 (assume ) Wholesaler supplied (SWP) Water Recycling (potable) Surface water Local groundwater Seawater desalination, transfers, exchanges, other

STEP 3: Calculate Self-Certified Supply Conservation Standard (STEP 1) Average Annual Potable Water Demand - (STEP 2) [Available] Potable Water Supply in 2019 NEGATIVE (-): Surplus supply, conservation = 0% POSITIVE (+) : Shortfall, conservation = shortfall/avg. demand (%)
