2015 URBAN WATER MANAGEMENT PLAN <br />Table 2 -8: Projected Water Demands for Housing Needed for Low Income Households (AF) <br />The Water Conservation Act of 2009, SBx7 -7, signed into law on February 3, 2010, requires the State of <br />California to reduce urban water use by 20 percent by the year 2020. The City must determine baseline <br />water use during their baseline period and water use targets for the years 2015 and 2020 to meet the <br />state's water reduction goal. The City may choose to comply with SBx7 -7 individually or as a region in <br />collaboration with other retail water suppliers. Under the regional compliance option, the City is still <br />required to report its individual water use targets. The City is required to be in compliance with SBx7 -7 <br />either individually or as part of the alliance, or demonstrate they have a plan or have secured funding to <br />be in compliance, in order to be eligible for water related state grants and loans on and after July 16, <br />2016. <br />For the 2015 UW MP, the City must demonstrate compliance with its 2015 water use target to indicate <br />whether or not they are on track to meeting the 2020 water use target. The City also revised their <br />baseline per capita water use calculations using 2010 U.S. Census data. Changes in the baseline <br />calculations also result in updated per capita water use targets. <br />DW R also requires the submittal of SBx7 -7 Verification Forms, a set of standardized tables to <br />demonstrate compliance with the Water Conservation Act in this 2015 UWMP. <br />2.5.1 Baseline Water Use <br />The baseline water use is the City's gross water use divided by its service area population, reported in <br />gallons per capita per day (GPCD). Gross water use is a measure of water that enters the distribution <br />system of the supplier over a 12 -month period with certain allowable exclusions. These exclusions are: <br />• Recycled water delivered within the service area <br />• Indirect recycled water <br />• Water placed in long term storage <br />• Water conveyed to another urban supplier <br />• Water delivered for agricultural use <br />arcadis.com 5 _30 2 -10 <br />
