FHZ delineations can identify areas that are vulnerable to flooding and sedimentation that occur after a wildfire, thereby directing the deployment of resources after a fire into watersheds that have the most at-risk assets downstream. In wildfire susceptible areas, the FHZ mapping process can help direct stakeholders toward conservation and rehabilitation of areas critical for the storage of sediment and debris (e.g., areas upstream of vulnerable communities and/or water storage facilities).
