Description: At-risk communities are referenced in Part B of the HFRA Wildland Urban Interface (WUI) definition. Some at-risk communities have been digitized based on the Federal register list of At-Risk Communities, 2001. Other communities from wildfirerisk.org (from the Research Data Archive file named RDS 2020-0016 supplements) have also been included. Additionally, at-risk communities can be identified by states and/or counties lists. Local data stewards can also add at-risk communities. All at risk communities must met the definition of an at-risk community in Part B of HFRA: (B) in the case of any area for which a community wildfire protection plan is not in effect— (i) an area extending 1⁄2-mile from the boundary of an at-risk community; (ii) an area within 11⁄2 miles of the boundary of an at-risk community, including any land that— (I) has a sustained steep slope that creates the potential for wildfire behavior endangering the at-risk community; (II) has a geographic feature that aids in creating an effective fire break, such as a road or ridge top; or (III) is in condition class 3, as documented by the Secretary in the project-specific environmental analysis; Some data sources used to spatially locate these at-risk communities are point features, and therefore extent of the community must be estimated. To estimate the community extent, all at-risk communities that were found in the Census_Place EDW data set were used to find the median size of those at-risk communities. The median size has been rounded to a 1-mile buffer. That community extent can be adjusted by digitizing a more accurate community extent with local knowledge of the actual size of the community. The at-risk communities in this layer will be buffered using the buffer distance field which is defined as:Per the HFRA WUI definition, an at-risk community is buffered by 0.5 miles unless there are sustained steep slopes, a geographic feature that will aid in a creating a fuel break, or is in Very High Wildfire Hazard Potential. If the area between 0.5 miles and 1.5 miles from the community meet any of these criteria, then Buffer_Distance field should be changed to 1.5 miles. For estimated community extents, it is the estimated extent that will be buffered. There have been legal court decisions on the interpretation of HFRA WUI that only apply to regional areas, and because of this, direction may change between FS Regions. Verify the official Regional direction for using HFRA WUI. Outside of areas impacted by court rulings, HFRA_CWPP_WUI (PartA) can be used in conjunction with At-Risk Communities (Part B) and Evacuation Routes (Part B) that are stored separately. Each region is only responsible for populating data within their Region.The HFRA_AtRisk (communities) will be buffered and combined with HFRA_Evac (routes) and HFRA_CWPP_WUI boundaries to produce the HFRA_WUI data layer published in the Enterprise Data Warehouse (EDW). The HFRA_WUI layer is designed ONLY for use with HFRA Fuels Categorical Exclusions, where HFRA WUI is legally required, when following USFS direction, and fiscal decisions, specifically funds granted in the Inflation Reduction Act. Other WUI layers should be used outside of the purposes listed above, like the USFS & University of Wisconsin SILVAS WUI.
