Learn about the data sources used to determine community wildfire risk.

Community Risk measures the threat wildfire poses to a community relative to other communities throughout the U.S. along four categories: Infrastructure (including emergency services, utilities, and transportation), Social services, Residential properties, and Commercial properties. 

Wildfire Projections

The First Street Foundation Wildfire Model is used to determine burn probability and ember exposure to facilities and infrastructure in all four categories noted above. The Wildfire Model is a nationwide model that uses U.S. Federal Government open data as a basis, with additional data from a variety of sources to determine property-level wildfire risk assessments that account for changing environmental conditions  to allow individuals, communities, businesses, and governments to understand and prepare for their wildfire risk. Use Risk Factor to find community-level wildfire risk assessments.

Data sources used to determine Community Risk 

The data used to analyze the risk of infrastructures and roads come from a variety of public data sources. Property and land use data are supplied through a partnership with Lightbox. Road centerline data are sourced from the US Census Bureau’s TIGER data. Infrastructure facility data are from a variety of sources including the US Environmental Protection Agency.
