For the HFRA_WUI feature class consolidates HFRA_CWPP, HFRA_AtRisk_Buffered, and HFRA_Evac_Buffered. The HFRA_CWPP feature class represents the WUI as described or mapped in the Part A definition of HFRA_WUI, 2003. The CWPP data is developed by counties, therefore the Forest Service is not the authoritative source for these boundaries. The CWPP areas are consolidated into the Forest Service system to facilitate legal and fiscal interpretations of WUI areas. These transactional HFRA_CWPP boundaries have been combined with Part B definition of buffered HFRA_AtRisk (communities) and buffered HFRA_Evac (routes) where legally appropriate. The EDW HFRA_WUI layer will be considered the authoritative data source and 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 (IRA). Examples of IRA funding that use HFRA WUI include priority landscapes and keystone partnerships. To filter comma delimited fields, such as source, use "contains" in the definition query or selection by attribute functions.

HFRA_CWPP, HFRA_AtRisk, HFRA_Evac have all been combined into one national layer to show the full extent of HFRA WUI. The first step to combine data is to dissovle HFRA_CWPP, HFRA_AtRisk, and HFRA_Evac independtly on the FS Region that submitted the data. Then in FME, and Area On Area Overlayer produces a union of all three of the layers. The field "Source" is populated with the name of every layer that occupied that spatial area in a comma separated list. For example, Source may look like "CWPP, At-Risk Community", or "CWPP", or "CWPP, At-Risk Community, Evacuation Route". Each FS Region is only responsible for populating data within their Region. Becuase of buffers there is potential for regional data to overlap into another region. Data stewards should review data that is spataily located in their region (field: "Region") when the field "RegionSubmitted" is a defferent region. FS Regions should not be adding data that is entirely outside of their region, and any data where the value for "RegionSubmitted" is not included in the value for "Region" will be excluded.

This is an interim layer until all data and sources can be moved to appropriate SDE locations, and at this time only represents HFRA WUI on FS lands. Other US Departments and Agencies that are subject to the Healthy Forest Restoration Act did not participate in collecting this data.
