Limit development in high flood and high fire hazard areas

Understanding the climate hazard risks for communities across LA County is essential to keeping individuals safe and not facilitating development in risky settings. Current regulatory hazard maps and forward-looking climate hazard data allow us to identify the areas that are most at risk, including floodplains and the wildland-urban interface at the edge of developed areas.

Wildfire is an integral component of ecological processes in LA County, but it is also on the rise because of hotter temperatures, changing precipitation patterns, and wildland management practices. The numerous devastating wildfires across the region are a stark reminder of the risks posed to lives, homes, natural areas, and infrastructure. LA County is already seeing longer droughts punctuated by intense rain events, which not only increases fire risk, but leads to flood vulnerability. In planning for these climate-related hazards, it is important to support existing communities and better manage any future growth and development to reduce and avoid risks and impacts.
