THECITY 0k rM�i l COMPREHENSIVE EMERGENCY MANAGEMENT PLAN In addition to the large group meetings, additional follow up occurred via telephone and email to solidify the mitigation plan and priorities. The Mitigation Plan was also put on the City of Pleasanton's website, and comments were invited to be sent to LPFD's Disaster Preparedness Coordinator. After FEMA approves the multi jurisdictional plan, Pleasanton will place on the City Council agenda a resolution adopting the plan and strategies. The mitigation strategies will become an annex to Pleasanton's Emergency Management Plan. Hazard and Risk Assessment The ABAG multi jurisdictional Local Hazard Mitigation Plan, to which this is an Annex, lists nine hazards that impact the Bay Area, five related to earthquakes (faulting, shaking, earthquake- induced landslides, liquefaction, and tsunamis) and four related to weather (flooding, landslides, wildfires and drought). These hazards also impact this community, with the exception of tsunamis Pleasanton does not border the Pacific Ocean or the Bay, so tsunamis are not a hazard in this area. The multi jurisdictional plan did not detail out hazardous materials or aviation hazards in the City of Pleasanton. This information, along with additional details on flooding in the area, is provided below from Pleasanton's All Hazard Vulnerability Analysis and Pleasanton's Safety Element to the General Plan. Information on disasters declared in Alameda County is at: http://quake.abao.ca.qov/mifigation/disaster-historv.html The City examined the hazard exposure of the City urban land based on the information at ABAG's website at http:/ /quake.abaq.ca .qov /mitigation /pickdbh2.html. Of the 10,076 urban acres in the City: Earthquake Faulting According to the CGS Alquist Priolo Earthquake Fault Zone information on the ABAG website, the Northern Calaveras fault runs through the City. 386 urban acres are within the CGS study zone. Earthquake Shaking —All 10,076 urban acres are in the moderate to high categories of shaking potential, due to the close proximity of the Calaveras Fault, Mt. Diablo Thrust Fault, Greenville Fault and Hayward Fault. Earthquake- Induced Landslides— The California Geological Survey has not completed mapping of this hazard in the City of Pleasanton. However, because few areas have been mapped as landslides, this hazard is viewed as similar to that posed by weather related landslides as shown below. Earthquake Liquefaction -6,533 urban acres are in areas of moderate, high or very high liquefaction susceptibility o Flooding -720 urban acres are in the 100 -year FEMA flood plain, while 2,261 urban acres are in the 500 year flood plain ANNEX G Local Hazard Mitigation Annex 4 Updated 11/12/0.5
