Floodplain Hazards
Flooding in Crested Butte can occur year-round, particularly during spring snowmelt or when watercourses are blocked by debris or ice. Coal Creek is the primary flood risk area, with some risk also along the Slate River. Homes near these waterways are more vulnerable to flood damage.
In case of flooding or other disasters (e.g., wildfire), plan ahead for evacuation, visit Ready.Gov for more information.
Floodplain Insurance
The Flood Insurance Rate Map (FIRM) by FEMA designates high-risk flood areas and determines insurance requirements. The current map (2013) is used for Crested Butte. Properties in Special Flood Hazard Areas may be required to carry flood insurance, available through the National Flood Insurance Program (NFIP).
The Town is collaborating with the Colorado Water Conservation Board to update its FIRM map as of September 2022.
For more detailed flood information, see the 1992 RBD Engineering Report on Coal Creek: RBD Engineering Floodplain Report
Floodplain Development
If your property is in a Special Flood Hazard Area, you must apply for a Floodplain Development Permit before excavation or construction. This ensures your project doesn’t negatively impact the floodplain or neighboring properties.
Development within 20 feet of streams can disrupt floodplain functions like water retention, habitat, and wetland preservation.
