Final Report, 2010 Urban Water Management Plan - Culver City

historic and projected demographic data for each census tract number from 2005 through 2035.Figure 2-2 details the census tracts within the Culver City System.Annual estimates of historical population between 1997 and 2010 required for SBX7-7 areprovided in Table 2-1. The population estimates were developed following DWR TechnicalMethodology 2: Service Area Population. GSWC is considered a Category 2 water supplierbecause they maintain a Geographic Information System (GIS) of their service area. The perconnectionmethodology described in Appendix A of Technical Methodology 2 was used sinceannual estimates of direct service area population from SCAG or other local governmentagencies were not available. This method estimates annual population by anchoring the ratio ofyear 2000 residential connections to the year 2000 Census population. This ratio was thenlinearly scaled to active residential connections data to estimate population for the non-censusyears in which water supply data were available: 1997 through 2010. The residential billingcategory includes traditional single-family residential connections; however since GSWC doesnot have a specific multi-family billing category that only encompasses the apartmentcomplexes and other types of multi-family housing units, the ratio of year 2000 Census totalpopulation per residential connections was used for projecting population growth.Table 2-1:YearCulver City System Historical PopulationService Area Population1997 37,1501998 36,8971999 36,3712000 36,333 (1)2001 36,3802002 36,4652003 36,4182004 36,4182005 36,4132006 36,3712007 36,5402008 36,6672009 36,6572010 36,704Note:1.
