Very High Fire Hazard Severity Zones (AB337)

As a result of the Oakland Hills Fire (Tunnel Fire) of 1991, the Bates Bill (337) was passed in 1992 requiring CAL FIRE to work with local governments to identify high fire hazard severity zones within local responsibility areas throughout each county in the state. Over the years CAL FIRE has updated the maps and provided new recommendations to local governments.

Following the Bill, CAL FIRE periodically gathers new data and updates the mapping. This is a massive project requiring policy and procedure staff, prevention and planning staff, and the technical GIS skills of CAL FIRE’s Fire and Resource Assessment Program.

The current Fire Hazard Severity Zone mapping is available on the link provided here.
