Technical data for the Bozeman Creek and Tributaries floodplain mapping project is available for download on the city's ftp server at the link provided below. Data including hydrologic analyses, flood profiles, floodway data tables, and HEC-RAS modeling files are available. Contact the City of Bozeman if you have trouble accessing the ftp.
Currently effective FIRMs for the City of Bozeman have an effective date of September 2, 2011. These Flood Insurance Rate Maps replaced the 1988 version of the maps and substantially revised the Special Flood Hazard Areas mapped for the East Gallatin River and portions of Bridger Creek. No change in the mapped SFHA was made for Bozeman Creek and its tributaries with the 2011 FIRMs.
Members of the public are encouraged to view the official maps to determine if their property is effected. Hard copies are available for viewing at the City of Bozeman Engineering Department, located in the Stiff Professional Building at 20 E. Olive Street. The 2011 FIRMs can be viewed and downloaded at the links below. The FIRMs are also officially maintained in an online web map format by FEMA.
The City of Bozeman does not maintain official floodplain maps for Gallatin County. For information concerning official FEMA flood maps for properties outside of City of Bozeman limits, please contact the Gallatin County Floodplain Administrator with the Gallatin County Planning Department by calling 406-582-3130.
All structures with federally secured mortgages located in a Special Flood Hazard Area (SFHA) are required by federal law to carry a flood insurance policy. Flood insurance is underwritten by the federal government and is made available through the National Flood Insurance Program (NFIP). A typical homeowner or business owner insurance policy does not cover flood damages. Flood policies may be purchased from qualified local insurance agents.
