A Community Wildfire Protection Plan (CWPP) is defined by the 2003 Healthy Forest Restoration Act (HFRA) as a plan for an at-risk community that: (1) is developed collaboratively, (2) identifies and prioritizes fuel reduction projects, and (3) recommends measures to reduce the ignitability of structures. The 2019 Mammoth Lakes CWPP was developed by the Mammoth Lakes Fire Protection District in collaboration with the Town of Mammoth Lakes, the United States Forest Service and the Mammoth Lakes Fire Safe Council. It includes a current analysis of the probability of a severe fire and its effects, and offers solutions and mitigation recommendations for residents, fire personnel and community planning officials. It also helps clarify priorities for the protection of life, property and critical infrastructure in the Wildland Urban Interface (WUI).
