CAL FIRE MAP MAKER FULL
Understanding the relationships between fire hazard, exposure, and vulnerability of households and communities is critical for developing and targeting response and adaptation strategies.įires cause a diverse set of social, economic, and environmental harms, and many questions remain about the full range of impacts and their geographic and temporal scales. The need for adaptation is especially acute in California, where 15 of the 20 most destructive fires on record have occurred since 2015, and climate change is projected to exacerbate wildfire risk.
Record-setting losses in recent years have triggered new urgency for households, businesses, and governments to adjust to increasing risk.

This relationship between income and fire experience may be a reflection of the impacts of repeated fires relative to mapped hazards or single fires, or it could point to a relationship between income and the success of fire prevention or suppression. Warming over the remainder of the century could add tens of thousands of homes to high-experience zones. Home values have grown more slowly in communities with high fire experience, translating to differences in total appreciation of $165M-$630M per year relative to communities with no fire experience.
High-hazard communities average higher incomes than low- and no-hazard communities conversely, communities with high fire experience average lower incomes than those with little to no experience. This analysis of three decades of fire footprints, hazard maps, and census and real estate data shows that communities with high fire experience differ substantially from communities with high fire hazard. Government hazard maps are often used to identify at-risk areas, but hazard zones and fire experience may have different implications for communities. Wildfires pose a large and growing threat to communities across California, and understanding fire vulnerability and impacts can enable more effective risk management.
