Table U-1: Comparison of Water Demands Water Use Water Demand Residents or Acreage Daily Demand (gpd) Annual Demand (AFY) Original Project Residents 120 gpd/capita 955 114,600 128.37 Landscaping 3,000 gpd/acre 0.94 2,820 3.16 Original Project Total 117,420 131.53 Modified Project Residents 120 gpd/capita 502 60,240 67.48 Landscaping 3,000 gpd/acre 0.48 1,440 1.61 Modified Project Total 61,680 69.09 Reduction in Water Demand -55,740 -62.44 GPD gallons per day; AFY = Acre Feet Yearly. The increase in demand for water supplies from the Modified Project would be 2.3 percent of the UWMP’s anticipated annual increase of 3,028 AFY (DEIR page 4.13-8), which is less than the 4.3 percent increase that would result from the Original Project. Therefore, the Modified Project would require less water from existing entitlements than the Original Project, and no new or greater impacts related to water would occur from implementation of the Modified Project. Wastewater As shown in Table UT-1, the reduction of 240 residential units that would occupy an estimated 453 residents would result in a 55,740 gpd reduction of water demand. The reduction of water demand would generate a reduction in wastewater generation. As the existing wastewater infrastructure would be able to adequately accommodate the Original Project, it would also be able to accommodate the reduced flows from the Modified Project. Therefore, no new or greater impacts related to wastewater would occur from implementation of the Modified Project. Drainage Consistent with the Original Project, implementation of the Modified Project would include compliance with all required laws, permits, and plans, through implementation of a SWPPP and WQMP that would be approved by the City prior to receipt of construction and operational permits. The DAMP would require runoff volume to be filtered through the detention and drywell systems prior to discharge off-site to manage stormwater drainage and protect water quality. Thus, the Modified Project would not generate additional runoff volumes, and DAMP required treatment systems would remove pollutants from onsite runoff. Therefore, consistent with the Original Project, the Modified Project would result in less than significant impacts related to drainage facilities and water quality. No new or greater impacts related to drainage and water quality would occur from implementation of the Modified Project. Conclusion for Utilities and Service Systems The Modified Project would develop 240 fewer residential units (48.4 percent less) than the Original Project, which would result in 453 fewer residents at full occupancy. The reduction in residents would equate to a reduced demand for water supplies and wastewater infrastructure capacity. In addition, the Modified Project would also filter runoff pursuant to permitting requirements. Thus, no new or greater impacts related to utilities or services systems would occur from implementation of the Modified Project. Based on the foregoing, none of the conditions identified in CEQA Guidelines Section 15088.5 that would trigger the need to prepare a recirculated EIR or other environmental document exist. The Modified Project would not result in either a new significant environmental impact or a substantial increase in the severity of a previously identified impact. 2-185
