South Coast Technology Center Project CEQA Exemption 15183 area. Therefore, in compliance GPU PEIR MM GEO-2, the proposed Project would conduct spot- check monitoring during construction to identify potential fossils and the Iithological transition to Pleistocene sediments. If Pleistocene -aged sediments are discovered at depth, monitoring shall transition to full-time as ground -disturbing activities occur at or below this identified depth because these Pleistocene units have been identified as high sensitivity for paleontological resources. Additionally, the proposed Project would comply with GPU PEIR MM GEO-3, which requires work be halted within a 50-foot radius in case of a fossil discovery. Consistent with the GPU PEIR, less than significant impacts related to paleontological resources would occur after the implementation of GPU PEIR mitigation measures. 4.7.3 Conclusion The Project is consistent with the General Plan Update. With implementation of RR G-1 and RR G-2, MM GEO-2, and MM GEO-3 identified in the GPU PEIR, the proposed Project would not have any specific effects which are peculiar to the Project or the Project Site. There are no project - specific impacts or potentially significant off -site or cumulative impacts that the GPU PEIR did not analyze, and there are no new significant or substantially more severe impacts to geology and soils than anticipated by the GPU PEIR. 4.7.4 Applicable GPU PEIR Regulatory Requirements/Mitigation Measures: RR G-1 Every public agency enforcing building regulations must adopt the provisions of the California Building Code (CBC), which is Title 24, Part 2 of the California Code of Regulations. The most recent version is the 2019 CBC (effective January 1, 2020). The CBC is updated every three years and provides minimum standards to protect property and public safety by regulating the design and construction of excavations, foundations, building frames, retaining walls, and other building elements to mitigate the effects of seismic shaking and adverse soil conditions. The CBC also contains provisions for earthquake safety based on factors including occupancy type, the types of soil and rock on -site, and the strength of ground shaking with specified probability of occurring at a site. RR G-2 Santa Ana Municipal Code, Chapter 8, Buildings and Structures. These codes address grading standards, excavation, and fills. This also includes compliance with regulations for unreinforced masonry structures in accordance with "Unreinforced Masonry Law," found in California Government Code §§ 8875 et seq. The City of Santa Ana Building Official may place additional requirements upon the construction of infrastructure, buildings, and other improvements based on the findings from plan check, soils testing, and geotechnical investigations. RR G-3 Santa Ana Municipal Code Section 39-51 requires that all buildings or structures within the city that require plumbing fixtures must be connected to a public sewer. MM GEO-219 Low -to -High Sensitivity. Prior to issuance of a grading permit for projects involving ground disturbance in previously undisturbed areas mapped with "low -to -high" paleontological sensitivity (see Figure 5.6-3), the project applicant shall consult with a geologist or paleontologist to confirm whether the grading would occur at depths that could encounter highly sensitive sediments for paleontological resources. If confirmed that underlying sediments may have high sensitivity, 19 The Cultural and Paleontological Resources Identification Memorandum (Attachment C) was prepared in part to fulfill the requirements of GPU PEIR MM GEO-2.
