South Coast Technology Center Project CEQA Exemption 15183 4.5 Cultural Resources 4.5.1 GPU PEIR Findings The GPU PEIR concluded that future development under the General Plan Update could adversely impact the City's numerous historical properties listed in national, state, and local registers. Implementation of RR CUL-2 through RR CUL-6 and GPU PEIR MM CUL-1 through MM CUL-3 would be required. Specifically, GPU PEIR MM CUL-1 would require a historical resources assessment (HRA) for structures 45 years or older. GPU PEIR MM CUL-2 would require the maximum use of the Secretary of the Interior's Standards for the Treatment of Historic Properties with Guidelines for Preserving, Rehabilitating, Restoring and Reconstructing Historic Buildings to ensure that projects involving relocation, conversion, rehabilitation, or alteration of a historic resources would not impair any historical significance. In the event that impacts to historical resources cannot be avoided, GPU PEIR MM CUL-3 would require the affected historical resources to be thoroughly documented before issuance of any permits and may also require additional public education efforts and/or memorialization of the historical resource. However, impacts to historical resources would still be significant and unavoidable. The GPU PEIR stated that development involving ground disturbance within the plan area has the potential to impact known and unknown archaeological resources. To reduce impacts to archaeological resources and prior to ground -disturbing activities, GPU PEIR MM CUL-4 requires an Archaeological Resources Assessment be conducted under the supervision of a qualitied archaeologist. If potentially significant archaeological resources are identified and impacts cannot be avoided, GPU PEIR MM CUL-5 requires a Phase II Testing and Evaluation investigation be performed by a qualified archaeologist. If the Archaeological Resources Assessment required by GPU PEIR MM CUL-4 does not identify archaeological resources but indicates the project area to be highly sensitive for archeological resources, then GPU PEIR MM CUL-6 requires a qualified archaeologist and a Native American monitor culturally affiliated with the project area to monitor all ground -disturbing activities in the areas of high archaeological sensitivity. However, if the Archaeological Resources Assessment does not identify potentially significant archaeological resources but indicates that the site has moderate sensitivity for archaeological resources, then GPU PEIR MM CUL-7 requires that a qualified archaeologist be retained on -call. With implementation of GPU PEIR MM CUL-4 through MM CUL-7, impacts to archaeological resources would be less than significant. As stated in the GPU PEIR, the potential for disturbance of human remains is low since development in accordance with the General Plan Update would be largely limited to infill sites and previously disturbed land in an urban environment. The GPU PEIR determined that compliance with California Health and Safety Code Section 7050.5 (RR CUL-1) and Public Resources Code Section 5097.98 would ensure that impacts to human remains would be less than significant. 4.5.2 Project Analysis The following section evaluates potential impacts to cultural resources that would result from the construction and operation of the proposed Project. The analysis is primarily based upon Attachment C, Cultural and Paleontological Resources Identification Memorandum (Cultural Memorandum). The Cultural Memorandum was prepared to fulfill the requirements of GPU PEIR MM CUL-4. July 2024 Page 37
