This guide contains resources for local governments to address increased flood risk and debris flows that can occur after large wildfires. This guide is a resource to communities affected by a wildfire that need to navigate the complex web of federal and state programs and agencies. While wildfires generate many hazards, this guide focuses on two topics: increased flood hazard, and increased debris flow hazard. This does not minimize other concerns after a fire, such as public safety on transportation and recreation, ecosystem restoration, and economic recovery. The main body of this guide is relatively short, with much more detail in the appendices. This guide first explains post-fire risks for flooding and debris flows, followed by general principles on how to address these risks. It explains agency roles and gives real examples using case studies. Appendix A has case studies about responses to post-fire threats. The case studies are from the Eagle Creek, Canyon Creek, Stouts Creek, and Carlton Complex Fires. Appendix B has agency summaries of the agencies that assist with post-fire flood risk. Appendix C lists the possible assistance for local governments, with eligibility information.
