Local Risk Factors
1991 Fire Legacy
Despite rebuilding, many of the same conditions that caused the Tunnel Fire remain: dense vegetation, steep terrain, Diablo winds, and narrow roads.
Dense Urban-Wildland Interface
Tens of thousands of homes are built directly into fire-prone hillside vegetation with minimal defensible space.
Extreme Diablo Wind Exposure
The hills are the first terrain feature that hot, dry Diablo winds hit after crossing the Central Valley, creating extreme fire conditions.
Eucalyptus Forests
Extensive eucalyptus plantations produce massive ember showers and burn with extraordinary intensity.

Protecting Your East Bay Hills Home & Family
Living in a fire-prone area means being proactive. Here are the steps every East Bay Hills homeowner should take to protect their property and prepare for wildfire season.
Evacuation Planning
The 1991 Oakland Hills fire killed 25 people and destroyed 3,000+ homes in hours. East Bay Hills neighborhoods have narrow, winding streets that gridlock during evacuations. Know multiple exit routes, register for AC Alert (Alameda) or CWS (Contra Costa), and leave at the first warning.
Defensible Space
Eucalyptus, Monterey pine, and dried grass create extreme fire conditions in the East Bay Hills. Remove eucalyptus bark buildup around trees near structures. The Diablo Fire Safe Council offers cost-sharing programs and the East Bay Regional Park District conducts fuel reduction on adjacent parkland.
