4.7 GEOLOGY AND SOILS According to Appendix G of the CEQA Guidelines, a project would normally have a significant effect on the environment if the project would: GEO-1 Directly or indirectly cause potential substantial adverse effects, including the risk of loss, injury, or death involving: i. Rupture of a known earthquake fault, as delineated on the most recent Alquist-Priolo Earthquake Fault Zoning Map, issued by the State Geologist for the area or based on other substantial evidence of a known fault? Refer to Division of Mines and Geology Special Publication 42? ii. Strong seismic ground shaking? iii. Seismic -related ground failure including liquefaction? iv. Landslides GEO-2 Result in substantial soil erosion or the loss of topsoil? GEO-3 Be located on a geologic unit or soil that is unstable, or that would become unstable as a result of the project, and potentially result in on- or off -site landslide, lateral spreading, subsidence, liquefaction or collapse? GEO-4 Be located on expansive soil, as defined in Table 1 S-1-B of dze Uniform Building Code (1994), creating substantial direct or indirect risks to life or property? GEO-5 Have soils incapable of adequately supporting the use of septic tanks or alternative waste water disposal systems where sewers are not available for the disposal of waste water? GEO-6 Directly or indirectly destroy a unique paleontological resource or site or unique geologic feature? Summary of Impacts in the GP EIR As discussed in Section 5.6, Geology and Soils, the city's location and underlying geology make it likely to experience seismic hazards, including strong seismic ground shaking, and secondary hazards, like liquefaction. No active surface faults exist within the plan area. The city is subject to seismic ground shaking; however, future developments adherence to California Building Code and implementation of RR G-1 would reduce impacts to less than significant. Similarly, impacts from seismic -related ground failure which include liquefaction, lateral spreading, seismically induced landslides, and ground lurching would also be reduced to less than significant with adherence to the California Building Code (CBC), RR G-1, RR GH-2, and GP policies. Future development would comply with existing regulations, which includes preparation and submittal of a Stormwater Pollution Prevention Plan and a soil engineering evaluation and would reduce impacts to a less than significant level regarding soil erosion (GP EIR p 5.6-21). The city contains alluvial materials that have the potential for expansive soils and settlement and collapse of soils throughout the city, posing a hazard to Resolution No. 2024-072 Page 39 of 67
