The <br />"2005 Existing Land Use with 2009 Mapping" file was used for this evaluation. <br />In general, the hazard exposure of the city of San Leandro is remaining steady over time as the <br />amount of urban land remains constant (San Leandro is an essentially built -out community). San <br />Leandro actually reduced the acres of urban land in the 100 year flood zone over the last 10 years <br />due to changes in the new FEMA flood maps. The following table described the exposure of <br />urban land within the unincorporated County to the various hazards. <br />Exposure (acres of urban land <br />Hazard <br />2000 <br />2010 <br />Change <br />Total Acres of Urban Land <br />9,815 <br />9,924 <br />109 <br />Earthquake Faulting (within CGS zone) <br />14 <br />46 <br />32 <br />Earthquake Shaking (within highest two shaking <br />categories)' <br />2,063 <br />2,541 <br />4,604 <br />Earthquake - Induced Landslides (within CGS <br />study zone) <br />93 <br />93 <br />0 <br />Liquefaction (within moderate, high, or very <br />high liquefaction susceptibility <br />7,775 <br />7,501 <br /><274> <br />Flooding (within 100 year floodplain) <br />2,099 <br />1 1,341 <br />1 <758> <br />' In large part because the Ha -,A -, ard, Greenville, and Calaveras fault systems run through the County. <br />2 The California Geological Survey continues to map Alameda County and added the Livermore - <br />Altamont area in late 2009.
