Through community outreach and public education, we endeavor to make residents of the County aware of the risks of living within a Wildland Urban Interface and what they an do to protect their home and property from wildfire. Even urban parks such as Gateway National Recreation Area have wildland urban interface. The Fire Hazard Severity Zone (FHSZ) maps are developed using a science-based and field-tested model that assigns a hazard score based on the factors that influence fire likelihood and fire behavior. When possible, remove or thin the dead wood and the older trees beyond 100 feet from the house. The wildland-urban interface (WUI) is the area where urban development occurs in close proximity to wildland vegetation. A lock () or https:// means youve safely connected to the .gov website.

Many San Mateo County communities are located in areas that were historically prone to frequent natural wildfires. WUI maps for the conterminous U.S. were generated using building point locations, offering higher spatial resolution compared to previously developed WUI maps based on U.S. Census Bureau housing density data (Radeloff et al., 2017). Work will require extensive hiking in wildland urban interface, high desert, and riparian habitats. The data are provided in Arc/Info interchange formatted files which have been compressed (ZIP). Residents and businesses in the WUI - Wildland/Urban Interface - are subject to additional requirements and restrictions that help protect the community at large from conflagrations, and to reduce the impacts of wildfires that do occur. The Dept was required by SB 6109 to map the WUI in WA State for the purpose of county-based building code adoptions. Phone: (415) 820-7900 Fax: (415) 660-3500 info .
