Fire Hazard Severity Zones: WUI Update
2025 Fire Hazard Severity Zone (FHSZ) Maps
CAL FIRE has released the updated 2025 Fire Hazard Severity Zone (FHSZ) maps, identifying areas with moderate, high, and very high wildfire risk within Local Responsibility Areas (LRA). Check your property’s fire hazard classification and learn how these updates may impact you. Learn More
These maps are developed by **CAL FIRE under the direction of the State Fire Marshal.** Our local fire agency **does not control** the creation of the map but is required to ensure public review and feedback.
Why This Matters
California **Government Code Section 51179(a)** mandates that local agencies **"shall designate, by ordinance, moderate, high, and very high fire hazard severity zones within 120 days of receiving recommendations from the State Fire Marshal."** The Central Marin Fire Authority (CMFA) received these maps on **February 24, 2025**.
These maps provide critical data for **land use planning, building code enforcement, and wildfire risk mitigation strategies**. **Public input** helps validate data, identify concerns, and improve wildfire preparedness planning.
We encourage all residents to review the proposed maps, ask questions, and submit comments.

What Does It Mean If My Property Is in a Severity Zone?
The designation of a **Moderate, High, or Very High Severity Zone** may require **enhanced building requirements and re-sale inspections**.
For more information, visit the CAL FIRE informational page.
Is the Fire Severity Zone Map a Structure Loss Model?
No. These maps help local governments implement **wildfire mitigation strategies**, not predict individual structure losses.
