Cabrillo Town Center WATER SUPPLY ASSESSMENT FEBRUARY 13, 2023 21 Resolution No. 2015-025 by formally requiring all water consumers to reduce use by 12 percent relative to their 2013 consumption. Additionally, on August 4, 2015, a water wasting penalty rate was established by Resolution No. 2015-047. This new penalty rate permits City staff to penalize those users not meeting their water use reduction targets of 12 percent. The City of Santo Ana as a whole met its State mandated target; as a result, the City did not have to impose any monetary penalties on any of its users. As of January 18, 2022, Governor Newson proclaimed a drought state emergency for all counties in California. Emergency regulations went into effect and will remain in effect for one year.11 The City has adopted new water conservation requirements effected June 7, 2022; these regulations primarily target outdoor use. As example, the City limits outdoor watering to two days a week and only between the hours of 6 p.m. to 6 a.m.12 Such restrictions have significantly reduced water demands throughout California. In addition to these mandated restrictions, cities must follow the Water Conservation Act of 2009, also known as Senate Bill (SB)x7-7. This law required the State of California to reduce urban water use by 20 percent by the year 2020. The City must determine baseline water use during their baseline period and water use targets for the years 2015 and 2020 to meet the state’s water reduction goal. The City’s 2015 target was 123 gallons per capita per day (GPCD) and the 2020 target is 116 GPCD. The 2020 UWMP reported that the City has already met both the 2015 and 2020 targets which an actual use in 2015 of 83 GPCD. This is likely due to increased conservation as required by the Governor’s Executive Order during severe drought conditions throughout California. The City’s water demand has been decreasing in recent years due to the combination of the Governor’s Executive Order and SBx7-7 goals. While residential use is projected to decrease due to water efficiency measures, usage by CII is projected to increase. CII were broken down into commercial, industrial, and institutional/governmental for 2025 through 2045 as shown in Table 6 below. 11 SWRCB Water Conservation Portal – Emergency Conservation Regulation, accessed on 11/11/22.
