This feature service represents Fire Hazard Severity Zones (FHSZ) in State Responsibility Area (SRA) as effective April 1, 2024. FHSZ that was adopted as SRA in 2007 and due to regulatory processes are no longer classified as SRA have become classified as LRA. This map combines these areas with FHSZ maps recommended in LRA from 2007-2011. This should be considered an interim combination dataset until new FHSZ is mapped in LRA. Original CAL FIRE data can be found here: https://calfire-forestry.maps.arcgis.com/home/item.html?id=ac8ed44d76ed4988bceb07d35d80f4cb#overview

Additionally, County of San Diego OES clipped the original CAL FIRE data to only San Diego County and added a hazard class field (HAZ_CLASS) to include the original hazard classification description, with an addition of "No Designation" for all areas not covered by SRA or LRA described above. This modified data is specifically for use in the Know Your Hazards Tool shared by the County: https://www.alertsandiego.org/en-us/preparedness/maps.html
