Large wild\x1dres are increasing in Idaho.The Wildland-Urban Interface (WUI), the area whereis always going to be a threat of destruction to structures and other human development meetproperty and consequently loss of life As demand or intermingle with developed wildland, is at thefor housing grows and development expands greatest risk of damage by wildre. The WUI rangesoutward from large cities, the WUI is often the only from urban areas adjoining wildlands to isolatedlocation with the space to expand. Very frequently, ranges and cabins; the number of these structuresthat edge will border wild\x1dre-prone vegetation. has nearly doubled since 1993. Figure 4 highlightsWhen considering the future of wild\x1dre risk in the the locations of the highest vulnerability based onWestern United States, it will likely expand to more WUI boundaries throughout the state. As seen on thehomes and result in the greater property losses than map, the southwestern portion of the state has thewe have seen in the past. 3highest risk; this includes Washington, Payette, Gem, Boise, Ada, Elmore, Camas, and Blaine Counties. TheFLOODINGstructures within the WUI are the most challengingFlooding is the partial or complete inundation of to protect and human-caused re ignitions are mostnormally dry land. Types of ooding experienced in common here.2 As stated in the CoreLogic 2019Idaho are numerous and include: riverine ooding, Wild\x1dre Risk Report: ash oods, alluvial fan ooding, ice/debris jam ooding, levee/dam/canal breaks, stormwater, sheet The primary driver of wild\x1dre-related damage andor areal ooding, and mudows (especially after a destruction is the geographic relationship betweenwildre). Flooding has produced the most damaging property development and existing high-riskand costly disasters in Idaho, and signicant events wild\x1dre fuels. When development and fuels intermixhave occurred regularly throughout the history or where they are adjacent to each other, thereof the state (see Figure 5).2Natural Hazards 99'
