3.2.2 Urban Water Use TargetsRetail suppliers must identify their urban water use targets by utilizing one of four compliancemethods identified in SBX7-7. The four urban water use target development methods are asfollows:• Compliance Method 1 – 80 percent of baseline gpcd water use.• Compliance Method 2 – The sum of the following performance standards: indoor residentialuse (provisional standard set at 55 gpcd); plus landscape use, including dedicated andresidential meters or connections equivalent to the State Model Landscape Ordinance(70 percent of reference ETo); plus 10 percent reduction in baseline commercial, industrial,and institutional (CII) water use by 2020.• Compliance Method 3 – 95 percent of the applicable state hydrologic region target asidentified in the 2020 Conservation Plan (DWR, 2010).• Compliance Method 4 – A provisional method identified and developed by DWR through apublic process released February 16, 2011, which aims to achieve a cumulative statewide20 percent reduction. This method assumes water savings will be obtained through meteringof unmetered water connections and achieving water conservation measures in three wateruse categories: (1) indoor residential, (2) landscape, water loss and other water uses and(3) CII.GSWC elected to evaluate Compliance Methods 1 and 3 for selecting urban water use targetsfor the 2010 plan. The following section provides an explanation of the target calculations and asummary of the interim and compliance water use targets.Compliance Method 1 Calculation SummaryThe Compliance Method 1 2020 water use target was calculated by multiplying the base dailygpcd by 80 percent. A 20 percent reduction in baseline water use would require reduction of33 gpcd by 2020 as shown in Table 3-6. The 2015 interim target would be 147 gpcd with a 2020water use target of 130 gpcd.Table 3-6:2020 Water Use Target Method 1 Calculation SummaryDescriptionBaseline2015Interim Target2020 ComplianceTargetPer Capita Water Use (gpcd) 163 147 130Percent Reduction N/A 10% 20%Final Report, 2010 Urban Water Management Plan – Culver City Page 3-7Golden State Water Companyg:\adminasst\jobs\2010\1070001.00_gswc-uwmp\09-reports\9.09-reports\2011-08\grp3\gswc_culvercity_2010_uwmp-final.doc
