It is designed to support FEMA's Response and Recovery activities and flood insurance policy marketing initiatives. FLOODZN data exists for 54 of California's 58 counties. The counties for which data do not exist are Alpine, Butte, San Diego, and San Francisco. These data are pending. The original FEMA flood zone feature classes have been dissolved using a redefinition of just the flood related items. Items and linework pertaining to community extents, map panel boundaries, and other locator references found in the original data have been eliminated. More accurate data may be found by checking with individual County agencies.FLOODZN polygons represent FEMA Q3 Flood Data zones in California. It is intended for use in flood plain management, hazard analysis, and risk assessment activities. Individual County agencies may be able to supply more accurate Flood Zone data.Caltrans20010101floodznfloodznvector digital datahttp://www.dot.ca.gov/hq/tsip/gis/datalibrary/gisdatalibrary.htmlpublication date20010101-122.373728-121.46935837.90575237.454404-122.373728-121.46935837.45440437.905752ShapefileCaltrans, Federal Emergency Management Agency (FEMA) Caltrans TSI/GIS Data Branch Metadata Coordinator mailing and physical address Sacramento CA 95814
