2024-053 - Final Supplemental for The Related Bristol Specific Plan Project

water system improvements be confirmed through hydraulic studies to confirm compliance with engineering standards, and ensure that cumulative impacts do not occur. The WSA that was prepared for the proposed Project describes that the 2020 MWD UWMP details the ability to meet the demands of its member agencies, including the City of Santa Ana, through 2045. In addition, the City of Santa Ana 2015 UWMP, GPU FEIR, and 2020 UWMP confirmed the ability of the City to meet water needs in multiple dry year scenarios with buildout of the South Bristol Street Focus Area. Thus, the City would have water supplies available to serve the proposed Project and reasonably foreseeable development in normal, dry, or multiple dry years. Impacts related to a cumulatively considerable increase in water supply demands would be less than significant. (Draft Supplemental EIR at p. 5.15-12.) Wastewater: -Cumulative wastewater infrastructure impacts are considered on a systemwide basis and are associated with the overall capacity of existing and planned infrastructure. The cumulative system evaluated includes the sewer system that serves the Project site and conveys wastewater to the OCSD wastewater treatment and disposal system. With the proposed Project, the sewer system would have sufficient capacity to handle the increased flows resulting from implementation of the proposed Project. The continued regular assessment, maintenance, and upgrades of the sewer system by the City and OCSD would reduce the potential of cumulative development projects to result in a cumulatively substantial increase in wastewater such that new or expanded facilities would be required. Thus, increases in wastewater in the sewer system would result in a less than significant cumulative impact. (Draft Supplemental EIR at p. 5.15- 1 b.) Drainage: -The geographic scope for cumulative impacts related to stormwater drainage includes the geographic area served by the existing stormwater infrastructure for the Project area, from capture of runoff through final discharge points. The proposed Project would result in a reduction in stormwater runoff from the Project site. As a result, the proposed Project would not generate additional runoff that could combine with runoff from cumulative projects that could cumulatively combine to impact drainage. Thus, cumulative impacts related to drainage would be less than significant. (Draft Supplemental EIR at p. 5.15-21.) Solid Waste: -The geographic scope of cumulative analysis for landfill capacity is the service area for the Frank Bowerman Sanitary Landfill, which serves the Project area. The projections of future landfill capacity based on the entire projected waste stream going to these landfills is used for cumulative impact analysis. As described previously, the Frank Bowerman Sanitary Landfill has a maximum permitted capacity of 1 1,500 tons per day and in March 2023 had a maximum disposal of 8,909 tons and a remaining capacity of 2,591 tons per day (CalRecycle 2023). The 124.24 tons of solid waste per week from operation of the proposed Project would be 4.8 percent of the remaining daily capacity of the landfill. Due to this small percentage, the increase in solid waste from the proposed Project would be less than cumulatively considerable and would be less than significant.
