ELAN PROJECT <br />WATER SUPPLY ASSESSMENT NOVEMBER 2, 201 <br />practices such as watering during or right after rainfoll.10 The City continues to promote water <br />use efficiency and currently has a goal to continue to reduce water demands by 3% compared <br />to 2013 consumption. In addition, the City only allows outdoor watering to every other day or <br />Monday, Thursday, and Saturday and only between the hours of 6 PM and 6 AM.ii <br />Such restrictions have significantly reduced water demands throughout California. In addition <br />to these mandated restrictions, cities must follow the Water Conservation Act of 2009, also <br />known as 5enote Bill (SB) x7-7. This law required the State of California to reduce urban water <br />use by 20% by the year 2020. The City must determine baseline water use during their baseline <br />period and water use targets for the years 2015 and 2020 to meet the state's water reduction <br />goal. The City's 2015 target was 123 gallons per capita per day (GPCD) and the 2020 target <br />is 116 GPCD. The 2015 UWMP reported that the City has already met both the 2015 and <br />2020 water use targets with an actual use in 2015 of 83 GPCD. This is likely due to increased <br />conservation as required by the Governors Executive Order during severe drought conditions <br />throughout California. <br />The City's water demand has been decreasing in recent years due to the combination of the <br />Governors Executive Order and SBx7.7 goals. The City's water demands are then expected to <br />increase by approximately 8%from 2015 to 2040 as shown in the table below. <br />Table 7 Ofy of Santa Ana Projected Total Water Demands <br />D dnd T e <br />?Ol s, . <br />`::: 2020 ..

These estimates are approximately 10,000 AF less than what was <br />predicted in the 2010 UWMP further highlighting the conservative nature of UWMP preparation. <br />The 2015 Metropolitan UWMP stated that Metropolitan would be able to meet the demands of <br />its member agencies, including the City of Santa Ana, through 2040. Therefore, imported water <br />demands for the City are projected to be met through the 20-year requirements of SB 610 and <br />beyond. The City of Santa Ana 2015 UWMP also confirmed the ability of the local supplies <br />and the OC Basin to meet the growing demands of the City. The ability for the City to meet <br />these growing demands in multiple climate scenarios is explained in the sections below. <br />10 SWRCB Water Conservation Portal — Emergency Conservation Regulation, accessed on 09/06/2017.
