South Coast Technology Center Project CEQA Exemption 15183 The GPU PER concluded that waste generated by buildout of the General Plan Update could be accommodated by existing facilities. Additionally, all development pursuant to the General Plan Update would comply with the CALGreen Code, which requires that at least 65 percent of nonhazardous construction and demolition waste from nonresidential construction operations be recycled and/or salvaged for reuse. Policies in the General Plan Update also encourage land uses and strategies that reduce waste generation and support infill development projects that provide adequate and creative solutions for waste and recycling collection activities. Overall, with compliance with General Plan Update policies related to solid waste and implementation of RR U-7 and RR U-8.2, impacts related to solid waste were determined to be less than significant. As stated in the GPU PEIR, the forecasted increase in electricity and natural gas demand for the plan area is well within the forecasted demand in Southern California Edison's and Southern California Gas Company's service area, respectively. Furthermore, development pursuant to the General Plan Update would be required to comply with energy efficiency standards, appliance efficiency regulations, CALGreen, and policies of the General Plan Update for energy -efficient building design and maintenance practices. Therefore, the GPU EIR concluded that impacts related to other utilities, including electric power, natural gas, and telecommunications facilities would be less than significant. 4.19.2 Project Analysis The Project proposes to demolish three buildings and a parking structure to construct three new industrial buildings for office, manufacturing, and/or warehouse use. According to the Attachment N, Water Supply & Sewer Demand Assessment, prepared by Incledon Consulting Group, dated January 10, 2024, the proposed fixture units (i.e., drinking fountains, toilets, sinks) associated with the three new industrial buildings would result in a nearly 40 percent reduction in demand for water due to the change in building usage from office to industrial use. Thus, there would also be large reduction in wastewater. The proposed Project would connect to existing wastewater distribution and treatment infrastructure, which would have the capacity to serve the Project's reduced demand in addition to existing service commitments and would not require the expansion of existing facilities. Compliance with RR U-2 would ensure that OCSD connection fees are paid in accordance with Ordinance No. OCSD-40. Thus, Project impacts related to wastewater infrastructure and treatment would be less than significant and less than the impacts disclosed in the GPU PER. As stated above, the proposed Project would result in a nearly 40 percent reduction in water use due to the change in building usage from office to industrial use. The proposed Project would also require water for landscaping; however, water use for landscaping would be minimal as the proposed Project would use drought -tolerant landscape. Additionally, the proposed Project would comply with RR U-5, which requires the Project to be designed pursuant to the water conservation and efficiency requirements of the SAMC, and RR U-6, which requires payment of water connection fees. Since the Project Site's water demand would be significantly reduced compared to existing conditions, the City's existing water infrastructure and supplies would be sufficient to serve the Project. As such, the Project impacts related to water infrastructure and supply would be less than significant and less than the impacts discussed in the GPU PER. As discussed in Section 4.10, Hydrology and Water Quality, the Project would introduce a new use to the Project Site (i.e., industrial/warehousing), and thus, would be required to comply with the requirements of the General Industrial Permit and RR HYD-2. A preliminary WQMP has been prepared for the proposed Project to comply with the requirements of the County's NPDES Stormwater Program (RR HYD-4) and to be consistent with the Orange County Drainage Area July 2024 Page 97
