To provide a comprehensive, scientifically-based analysis of wildfire related hazards and risks in the Wildland Urban Interface (WUI) areas of the Beaver Creek Resort community. 2. Using the results of the analysis, generate recommendations designed to prevent and/or reduce the damage associated with wildfire to WUI values in the Beaver Creek study area. 3. Create a Community Wildfire Protection Plan (CWPP) document for Beaver Creek which conforms to the standards for CWPPs established by the Healthy Forest Restoration Act (HFRA). INTRODUCTION The Beaver Creek CWPP is a result of a community-wide planning effort including
