Teale Data Center maintains and provides natural hazard area data but does not make determinations for specific properties. Order form 2. Images of county maps can be viewed on line. Digital data files are available for downloading. Available in zipped export file format via ftp transfer.
Files contain polygons of fire hazard areas only.
Updates have happened as the result of urban expansion or land ownership changes, resulting in changes occurring in every county. 25 counties contain Very High Fire Hazard Severity Zones, and 33 do not. These are lands covered wholly or in part by timber, brush, undergrowth or grass, whether of commercial value or not, which protect the soil from erosion, retard runoff of water or accelerated percolation, and lands used principally for range or forage purposes. SRA is detemined by a combination of land ownership and fire protection criteria. Basically SRA occurs on non-federal lands for which fire protection is provided by the State of California or the federal government.
