This layer represents the Washington Wildland Urban Interface (WUI) as mapped for 2019 by WA State Dept. of Natural Resources - Wildfire & Forest Health Divisions under consultation from the USFS Rocky Mtn Research Station. The Dept was required by SB 6109 to map the WUI in WA State for the purpose of county-based building code adoptions. The WUI depicts areas of WA where structures and wildland overlap with specific structure densities.
