More than 800,000 acres of land across these SoCal counties have been classified under the highest fire hazard severity zone level.

Cal Fire said the maps are proactive, to be used in wildland-urban interface building standards for new construction and natural hazard real estate disclosures at the time of sale.

For the first time in over a decade, state officials will be updating fire maps for Southern California. This includes crucial information on the latest wildfire prone areas, fire risk zones and fire-building codes. The new maps will impact land-use decisions, building standards and wildfire mitigation strategies for local governments.
