Saticoy & Wells Community Plan and Code EIRSection 4.6 Geological Hazards• In areas mapped as having moderate or high risk of liquefaction,subsidence, or expansive soils• In areas within 100-year flood zones, in conformance with all FederalEmergency Management Agency regulations.Action 7.8Action 7.9To the extent feasible, require new critical facilities (hospital, police, fire,and emergency service facilities, and utility “lifeline” facilities) to belocated outside of fault and tsunami hazard zones, and require criticalfacilities within hazard zones to incorporate construction principles thatresist damage and facilitate evacuation on short notice.Maintain and implement the Standardized Emergency ManagementSystem (SEMS) Multihazard Functional Response Plan.The following Community Plan standard relates to geologic and seismic hazards.Action 11.7.1Review the integrity of barranca structures to evaluate hazards adjoiningdevelopment from failing or disintegrating barranca walls.Impact GEO-1 Future seismic events could produce ground shakingthroughout the Project Area as well as surface rupture in someareas where future development could be accommodated.Ground shaking and surface rupture could damage structuresand/or create adverse safety effects. However, compliancewith City policies, in combination with the requirements ofthe CBC and the Alquist-Priolo legislation, would reduce therisk associated with ground shaking and surface rupture to aClass III, less than significant, level.Similar to most of southern California, the Saticoy & Wells Project Area is subject to severeground shaking from any of a number of faults in the region. As shown in Table 4.6-1, thelargest ground-shaking events in the Project Area would occur from a maximum earthquake onthe Arroyo Parida-More Ranch, Mid Channel, Santa Ynez (East), and Malibu Coast Faults. Theonly potentially active fault in the Project Area is the Country Club fault, which crosses portionsof the neighborhood center on Telephone Road. Surface rupture could potentially occur alongthis fault line.All new development within the Project Area would conform to the California Building Code(CBC) (as amended at the time of permit approval), as required by law. This addressespotential impacts relating to ground shaking. In addition, the 2005 General Plan containspolicies that address risks from fault rupture. Action 7.7 requires geotechnical evaluation andmitigation prior to development of any site within an Alquist-Priolo earthquake fault zone orwithin 100 feet of a potentially active fault. Action 7.8 requires new critical facilities (hospital,police, fire, and emergency service facilities, and utility “lifeline” facilities) to be located outsideof fault zones. Implementation of these 2005 General Plan policies, in combination with CBCrequirements, on all new development in the Project Area would reduce impacts to a less thansignificant level.4.6-9City of Ventura
