Description: Functional WUI represents a classification of the land near buildings into zones that generally describe wildfire exposure along with risk mitigation activities appropriate for each zone. This dataset helps identify areas where structures and populations are most exposed to wildfire hazards.The Primary Exposure zone identifies where structures are immediately nearby burnable land cover. Mitigation efforts to reduce fire intensity and ember production in this may be warranted. Buildings in this zone would benefit from hardening measures to resist ignition.The Secondary Exposure zone identifies land where structures by lofted embers or by home-to-home spread even though they are not immediately located with vegetation types classified as burnable. Buildings in this zone would benefit from hardening measures to resist ignition, but defensible space is usually not required due to the heavily developed nature of the zone.Sources of Ember Load to Buildings are areas of burnable land cover that produces embers capable of reaching nearby buildings. The Wildfire Transmission Zone is the unpopulated land within about 2.4 km of a group of structures. Fires that originate within or spread to the Wildfire Transmission Zone have an immediate threat of reaching the nearby structures; fuel treatments that slow fire spread in this zone can reduce risk to these structures.The Low-to-No Exposure zone identifies where structures are beyond 1500m from a large (500 ha) contiguous blocks of burnable land cover. These are generally highly developed, urban areas. Flames—even from home-to-home spread—and embers have a relatively low likelihood of reaching structures in this zone, but smoke and evacuations could still impact this area.Water is classified as Non-burnable Water (NB8) in the Surface Fuel Map.
