With streaks of yellow, orange and red, Cal Fire’s new fire risk maps make plain the extent of fire danger in the Bay Area. The origin of the maps date back to one of the first major wildfires to burn into neighborhoods in the state: the 1980 Panorama Fire in San Bernardino County.

The new maps add 1.4 million acres of land statewide into higher fire severity categories, accompanied by stricter building and local planning code requirements for property owners.
