A wildland-urban interface (WUI) code is specifically designed to mitigate the risks from wildfire to life and property. If a product does not qualify for listing but meets the standard of the Materials and Construction Methods for Exterior Wildfire Exposure, Chapter 7A of the California Building Code will be listed in theWUI Product Handbook. National Wildfire Coordinating Group (NWCG) . WUI GIS data were designed to provide a spatially . Local Agency Very-High Fire Hazard Severity Zone.New buildings located in any Local Agency Very-High Fire Hazard Severity Zone for which an application for a building permit is submitted on or after July 1, 2008, shall comply with all sections of this chapter. The following ignition-resistant standards are designed to prevent embers from igniting a building: The Office of the State Fire Marshal's (SFM) Building Materials Listing Program (BML) was originally created to mandate that all fire alarm systems and fire alarm devices be approved and listed by the State Fire Marshal prior to sale or marketing within the state. State Responsibility Area MapsCAL FIRE adopted Fire Hazard Severity Zone maps for State Responsibility Areas in November 2007.

Ecological Applications 15:799- 805. If you live in an urban-interface area, consider these additional steps: Create at least a 30-ft. safety zone around your home. The San Mateo County Board of Supervisors and the California Coastal Commission approved the San Mateo County Local Coastal Program (LCP) in 1981. Update, 11/2008:CAL FIRE has determined that this county has no Very High Fire Hazard Severity Zones in LRA. Secure .gov websites use HTTPS The term Wildland Urban Interface (WUI) is not a designation of potential wildfire severity, but rather a somewhat loosely defined description of an area where urban development meets undeveloped lands at risk of wildfires. Buildings are now required to be constructed so that they have less chance of catching fire from burning embers from wildfires. Maps of intermix and interface WUI were generated using a range of circular neighborhood sizes, based on radius distances from 100 ? Note . Materials not listed by the SFM may still qualify for use provided they met all the requirements under Chapter 7A. Before sharing sensitive information, make sure you're on a federal government site.

The wildland-urban interface (WUI) is defined as the area where houses and other structures are built within or close to wildland vegetation (USDA and USDI 2001).The term is used in the context of wildfire to identify settlements that are potentially at risk from fire (Caton et al.
