nonirrigated. Hicksville loam's permeability is moderately slow and water capacity is high. This unit is suited to irrigated row, field, and vineyard crops. Hicksville loam has a storie index rating of 58 and a land capability of llw irrigated and IVw nonirrigated. San Joaquin loam, 2 to 8 percent slopes, eroded's permeability is very slow and water capacity is low. This unit is suited to irrigated vineyard crops. San Joaquin loam, 2 to 8 percent slopes, eroded, has a storie index rating of 20 and a land capability of Ne irrigated and nonirrigated. San Joaquin loam thick surface, 0 to 2 percent slopes's permeability is very slow and water capacity is moderate. This unit is suited to irrigated pasture. San Joaquin loam, thick surface, 0 to 2 percent slopes, has a storie index rating of 32 and a land capability of Ills irrigated and IVs nonirrigated. San Joaquin complex's permeability is very slow and water capacity is low. This unit is suited to irrigated pasture. San Joaquin complex has a storie index rating of 28 and a land capability of IVs irrigated and nonirrigated. 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. The project will not result in substantial soil erosion or the loss of topsoil because the project includes the conversion of existing structures, and no additional development. Any required improvements will be subject to grading and/or building permits. As a result, impacts to soil erosion or loss of topsoil will be less than significant. The project site is relatively flat terrain where landslides have not historically been an issue. A soils report will be required for grading and foundations and all recommendations from a soils report must be incorporated into the construction plans. Therefore, any risks resulting from being located on an unstable unit will be reduced to less than significant. The project will be served by an onsite septic tank or alternative waste water disposal system for the disposal of waste water. The Environmental Health Department is requiring a soil suitability/nitrate loading study to determine the appropriate system and design prior to issuance of building permit(s). The sewage disposal system shall comply with the onsite wastewater treatment systems standards of San Joaquin County prior to approval. A percolation test that meets absorption rates of the manual of septic tank practice or E.P.A. Design Manual for onsite wastewater treatment and disposal system is required for each parcel. With these standards in place, only soils capable of adequately supporting the use of septic tanks will be approved for the septic system. The San Joaquin County General Plan 2035 indicates that the county will protect significant archeological and historical resources by requiring an archeological report prepared by a qualified cultural resource specialist prior to the issuance of any discretionary permit or approval in areas determined to contain significant historic or prehistoric archeological artifacts that could be disturbed by project construction. In this way, the County can minimize damage to unique paleontological resources or sites or geologic features. PA-1900129 (UP)— Initial Study 14
