DENVER – The flood insurance rate map update process for the West Gallatin River and Bozeman Creek and its tributaries is getting closer to completion. Updated flood insurance maps will provide more accurate flood risk information that can help local officials and residents make informed decisions about reducing flood risks and purchasing flood insurance.

The mapping update project is a cooperative project involving the City of Bozeman, Gallatin County, Montana Department of Natural Resources, and the Federal Emergency Management Agency (FEMA).  It is part of a nationwide effort led by FEMA to increase local knowledge of flood risks and support actions to address and reduce those risks.

Before new flood insurance rate maps become effective, there is a 90-day Appeal Period during which local residents and business owners can provide additional data for consideration before the maps are finalized. This appeal period starts on September 20, 2018.

“Most of the existing floodplain maps for these rivers were produced from studies conducted more than 30 years ago” explained Tiffany Lyden, DNRC Floodplain Outreach Specialist. “Updating the existing maps is a key step in providing accurate information to help keep families, homes, businesses, and infrastructure safe from future flood events.”

County and City officials encourage residents and business owners to review the proposed flood insurance rate maps to learn about local flood risks, potential future flood insurance requirements, and any concerns or questions about the information provided.  The proposed maps can be viewed online at or, or at the Gallatin County Planning Office or the Bozeman City Engineering Department.  

If you have technical and scientific information, such as detailed hydraulic or hydrologic data, you may be able to appeal the flood risk information on the preliminary flood insurance rate maps during the 90-day Appeal Period. For further details on this process, visit or or contact Sean O’Callaghan, Gallatin County Floodplain Administrator, at 406-582-3130 or Brian Heaston, City of Bozeman Floodplain Administrator, at 406-582-2280.
