The Bowery Mixed-Use Project CEQA Findings of Fact City of Santa Ana 38 May 2020 onsite water distribution lines would only serve the proposed Project and would not provide water to any off-site areas. The construction activities related to the onsite water infrastructure that would be needed to serve the proposed multi-family residential and commercial uses is included as part of the proposed Project and would not result in any physical environmental effects beyond those identified throughout the Draft EIR. Therefore, the proposed Project would not result in the construction of new water facilities or expansion of existing facilities, the construction of which could cause significant environmental effects, and impacts would be less than significant. Impact Finding: The City would have sufficient water supplies available to serve the project and reasonably foreseeable development during normal, dry, and multiple dry years (Draft EIR at p. 5.16-7). Facts in Support of Findings: As shown in Draft EIR Table 5.16-4, the proposed Project would result in a total demand of 269 AFY at full occupancy, which would be a 245.27 AFY increase in comparison to the water demand from the existing buildings that are included in the UWMP assumptions. This equates to an 8.1 percent of the anticipated increase in water demand between 2015 and 2040 of 3,028 AFY that is anticipated by the 2015 UWMP. Thus, the City would have water supplies available to serve the Project. In addition, as shown in Draft EIR Table 5.16-2, the City’s available supply, including groundwater and imported water, will meet projected demand that includes the proposed Project during normal, single dry and multiple dry years. Therefore, impacts related to water supplies from the proposed Project would be less than significant. Wastewater Impact Finding: The Project would not require or result in the construction of new wastewater treatment facilities or expansion of existing facilities, the construction of which could cause significant environmental effects (Draft EIR at p. 5.16-11). Facts in Support of Findings: The Project includes replacing approximately 367 feet of the existing 8-inch City sewer line in Warner Avenue, between the Project site and the Orange County Sanitation sewer line in Red Hill Avenue, with a 10-inch sewer. In addition, the Project would install a new onsite sewer system that would connect to off-site City of Santa Ana sewer facilities. Approximately half the Project site would discharge wastewater directly into a City-owned manhole located at the intersection of Warner Avenue and Red Hill Avenue. The other half of the Project site would discharge wastewater into the improved 10-inch sewer in Warner Avenue to the existing 42-inch sewer in Red Hill Avenue. Based on results of the sewer flow monitoring and the City’s Design Criteria for wastewater generation rates, the sewer lines that would serve the Project site would have a peak flow half full capacity of 0.65 cfs which would is adequate capacity to accommodate the additional wastewater flows from the proposed Project. The construction activities related to replacing 367 feet of 8-inch water line with 10-inch water line within the Warner Avenue right of way and installation of the onsite sewer infrastructure that would serve the proposed Project, is included as part of the proposed Project and would not result in any physical environmental effects beyond those identified throughout the Draft EIR. As the proposed Project includes facilities to serve the Project, it would not result in the need for construction of other 3-60
