► Policy S-P-5: The City shall ensure that all public facilities, such as buildings,water tanks, and reservoirs, are structurally sound and able to withstand seismic shaking and the effects of seismically induced ground failure. The Safety Element of the City general plan further states that all new development shall comply with the current CBC requirements and with California Health and Safety Code Section 19100 et seq. (Earthquake Protection Law). Soils and Erosion Control The Resource Conservation Element of the City general plan contains the following policy related to the project: ► Policy RC-P-10: Minimize soil erosion and loss of topsoil from land development activities,wind, and water flow. The Resource Conservation Element of the City general plan further states that all new development shall comply with the current CBC requirements for construction standards for specific soil types, and with CBC Chapter 70 regulating grading activities including drainage and erosion control. The City requires site-specific land management and development practices for proposed development projects, including appropriate mitigation measures to avoid or reduce erosion. Grading Permits In the City of Manteca, grading and construction are regulated through grading permits in compliance with the requirements of the most current version of the California Building Standards Code. 4.7.2 ENVIRONMENTAL IMPACTS ANALYSIS METHODOLOGY Evaluation of potential geologic and soil impacts was based on a review of documents pertaining to the project area, including the San Joaquin County General Plan 2010(San Joaquin County 1992),the City of Manteca General Plan 2023 (2003b), geotechnical reports prepared by Kleinfelder, field review of the proposed project site,geologic and soils maps, and published and unpublished geologic literature. The San Joaquin County and City of Manteca general plans are available for review at the City of Manteca Community Development Department, and project-related geotechnical reports are available for review at the City of Manteca Public Works Department. Impacts related to geology and soils that would result from implementation of the proposed project were identified by comparing existing data and environmental documents. THRESHOLDS OF SIGNIFICANCE For the purpose of this analysis,the following applicable thresholds of significance have been used to determine whether implementing the proposed project would result in a significant impact. These thresholds of significance are based on the State CEQA Guidelines. A geology and soils impact is considered significant if implementation of the proposed project would do any of the following: ► expose people or structures to potential substantial adverse effects, including the risk of loss, injury or death involving: • 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; Manteca WQCF and Collection System Master Plans EIR EDAW City of Manteca 4-7.15 Geology,Soils,and Seismicity
