State legislation passed in 1992 directed he California Department of Forestry and Fire Protection (Cal Fire) to work with local governments to delineate Fire Hazard Severity Zones throughout California. Cal Fire updated and adopted new Fire Hazard Severity Zone maps for each county in 2007. The agency used various types of data to map out these zones, which are ranked either Very High, High, or Moderate Fire Hazard Severity. All of these adopted zones apply to "State Responsibility Areas," which include land under the jurisdiction of state agencies and counties. Soon after, Cal Fire recommended to "Local Responsibility Area" jurisdictions (cities, towns, etc.) maps of Very High Fire Hazard Severity Zones using the same methods. Areas that are designated as Very High or High Fire Hazard Severity Zones are the most likely to experience wildfire, and structures in these zones can be potentially impacted.We have created this online mapping tool so that you can search for your address to find out if your home or business is located in one of these zones. You will also find more information about the steps you should take if your structure is located in a Fire Hazard Severity Zone.
