Saticoy & Wells Community Plan and Code EIRSection 4.6 Geological Hazardsinfrastructure facilities that are sensitive to slight changes in gradient, such as wells, sewers, andother underground utility lines.The Community Project Area is not located in an area threatened with subsidence orhydroconsolidation.4.6.2 Impact Analysisa. Methodology and Significance Thresholds. The Project would result in potentiallysignificant impacts if development would result in substantial adverse physical impactsassociated with any of the following conditions:• Expose people or structures to potential substantial adverse effects, including the riskof loss, injury, or death involving rupture of a known earthquake fault, strongseismic ground shaking, seismic-related ground failure, including liquefaction, orlandslides, or seismic-related inundation from tsunami or seiche• Be located on a geologic unit or soil that is unstable, or that would become unstableas a result of the project, and potentially result in on- or off-site landslide, lateralspreading, subsidence, liquefaction, or collapse• Be located on expansive soil, creating substantial risks to life or propertyDevelopment facilitated by the Project would not result in substantial soil erosion or the loss oftopsoil nor would it result in the loss of a unique geologic feature. The Initial Study does notidentify significant soil erosion impacts. No unique geologic features have been identified inthe Project Area as the Project Area is generally flat and consists of mostly suburban andagricultural uses. Therefore, these conditions were not addressed as potential effects resultingfrom implementation of the Project.b. Project Impacts and Mitigation Measures. A discussion of the project impacts andmitigation measures follows.The following 2005 General Plan policy and actions relate to geologic and seismic hazards.Policy 7BAction 7.6Action 7.7Minimize risks from geologic and flood hazards.Adopt updated editions of the California Construction Codes andInternational Codes as published by the State of California and theInternational Code Council respectively.Require project proponents to perform geotechnical evaluations andimplement mitigation prior to development of any site:• With slopes greater than 10% or that otherwise have potential forlandsliding• Along bluffs, dunes, beaches, or other coastal features• In an Alquist-Priolo earthquake fault zone or within 100 feet of anidentified active or potentially active fault4.6-8City of Ventura
