Post-fire debris-flow hazard assessments for recently burned areas in the western United States are provided free to any interested Federal, State, or Local Agency, or to any private organization, company or individual. These assessments rely upon field-validated estimates of soil burn severity in geospatial format. These data should be provided at the time of the request.

Due to limitations in the model, we may not be able to accommodate requests for assessments in certain burn areas, such as those with very low relief terrain, very small burn areas, or in areas that are outside of the western United States.

Please direct your requests, or any questions you may have regarding the assessment process, to:

Dennis Staley
dstaley@usgs.gov

or

Jason Kean
jwkean@usgs.gov

Response time is dependent upon the number of assessments that have previously been requested, though we strive to respond to any request within 3 business days.
