THE CITY OF Chapter 4, : , _,1;,, Water Use Characterization PL£ASANTON 4.4 ESTIMATING FUTURE WATER SAVINGS Water savings from codes, standards, ordinances, or transportation and land use plans can decrease the water use for new and future customers. As indicated in Table 4-7, to be conservative, these "passive" water savings have not been included in the City's projected future water demands. Table 4-7 indicates that lower income residential demands are included in the City's water demand projections, as is detailed in Section 4.5. Table 4-7. Inclusion in Water Use Projections (DWR Table 4-5 Retail) Are Future Water Savings Included in Projections? (Refer to Appendix K of UWMP Guidebook) I No If "Yes" to above, state the section or page number, in the cell to the right, where citations of the codes, ordinances, or otherwise are utilized in demand projections are found. Are Lower Income Residential Demands Included In Projections? I Yes 4.5 WATER USE FOR LOWER INCOME HOUSEHOLDS SB 1087 (2006) requires that water providers develop written policies that give priority to development that includes affordable housing to low income households. The projections shown in Table 4-3 include water use for single family and multi -family residential housing needed for low income households, as identified in the City's Housing Element. A lower income household is defined as a household that has an income below 80 percent of the Area Median Income, adjusted for family size. According to the American Census Bureau, 2018 American Community Survey 5 -year Estimate, approximately 18.35 percent of City households are low income Therefore, approximately 18.35 percent of the City's residential water demands are attributed to low income households, assuming an average household size of four. This proportion is assumed to remain constant in the future, and apply equally for both single family and multi -family residential water use sectors. In other words, 18.35 percent of single family residential demands are assumed to be for low income single family households, and 18.35 percent of multi -family residential demands are assumed to be for low income multi -family households. The water demand projections for low income households are summarized in Table 4-8. Table 4-8.
