Impact Discussion: a) The geology of San Joaquin County is composed of high organic alluvium, which is susceptible to earthquake movement. The project will have to comply with the California Building Code (CBC)which includes provisions for soils reports for grading and foundations as well as design criteria for seismic loading and other geologic hazards based on fault and seismic hazard mapping. All recommendations from a soils report must be incorporated into the construction plans. Therefore, impacts to seismic-related (or other) landslide hazards will be less than significant. b) The project will not result in substantial soil erosion or the loss of topsoil because the project will require a grading permit and the grading will be done under permit and inspection by the San Joaquin County Community Development Department's Building Division. As a result, impacts to soil erosion or loss of topsoil will be less than significant. c-d) The project site is relatively flat terrain where landslides have not historically been an issue.A soils report will be required PA-1800106 (RAA, UP)—Initial Study 13
