Vista Charter Public Schools District Office and Outdoor Space Project CEQA Exemption 15183 expansive in accordance with the 2022 California Building Code, Section 1803.5.3.14,15 As such, no impacts related to unstable or expansive soils would occur. In compliance with RR G-3, construction and operation of the proposed project would not involve the use of septic tanks or alternative wastewater disposal systems. As such, compliance with existing regulatory requirements would ensure no impact related to the use of such systems would occur. With regards to paleontological resources, the project site is disturbed and built out in nature; however, sediments in the project site are considered to have paleontological sensitivity increasing with depth. Specifically, the project site is underlain by silty sand of alluvial fan deposits (Qyfsa) which contain "low -to -high" paleontological sensitivity; refer to GPU EIR Figure 5.6-3, Paleontological Sensitivity. As such, in the event of paleontological resource discovery, the proposed project would comply with GPU EIR Mitigation Measure GEO-3, which requires construction work to halt within a 50-foot radius of a find. With adherence to the City's existing requirements for paleontological resources, less than significant impacts related to paleontological resources would occur. 4.7.3 Conclusion Overall, the project is consistent with the General Plan Update. With implementation of RR G-1 and G-2 and Mitigation Measure GEO-3 identified in the GPU EIR, the proposed project would not have any specific effects which are peculiar to the project or the site. There are no project - specific impacts or potentially significant off -site or cumulative impacts the GPU EIR failed to analyze, and there are no new significant or substantially more severe impacts to geology and soils than anticipated by the GPU EIR. Applicable GPU EIR 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. 14International Code Council, 2022 California Building Code, Title 24, Part 2, https://codes.iccsafe.org/content/CABC2022P1/chapter-18-soils-and-foundations, accessed July 26, 2023. 15 U.S. Department of Agriculture, Natural Resources Conservation Service, Web Soil Survey, https://websoilsurvey.nres.usda.gov/app/WebSoilSurvey.aspx, accessed July 26, 2023.
