The project aims to develop and deliver a database of wildfire-affected building footprints, classified by building type, attributed with structure separation distance (SSD), construction materials, and uncertainty categorized for this data. The database will cover significant spatiotemporal extents and include unique information from the National Fire Incident Reporting Systems and other databases. High-resolution pre-fire and post-fire-affected vegetation datasets will be derived at select fires. The project will assess the uncertainty in correlation studies, examine relationships between pre-fire and fire-affected vegetation, and evaluate WUI fire behavior models. • The project will focus on examining relationships between defensive actions and property treatments. • The project will assess the uncertainty in correlation studies. • The project will evaluate WUI fire behavior models. • The project will facilitate examining and enhancing current parcel and building-scale risk assessment approaches.
