The California Office of the State Fire Marshal has released its 2025 Fire Hazard Severity Zone maps for the state of California, including Irvine. These maps use the latest climate data, fire history, topography, and wildfire modeling to classify areas as Moderate, High, or Very High fire hazard zones.
The City of Irvine is required by law to adopt the map within 120 days after it is released by the State. It is also required to make the map available to the public and collect community input before it is adopted.
