Gallatin Mapping Updates
Gallatin County is currently working with the Federal Emergency Management Agency (FEMA) and Montana Department of Natural Resources and Conservation (DNRC) to update Flood Insurance Rate Maps for the West Gallatin River and Bozeman Creek and its tributaries. New Flood Insurance Rate Maps from this project are expected to be finalized in 2018 after a technical and public review process.
When finalized, the new maps could have effects on some property owners in mapped floodplains. If you are currently or will be mapped into a 100-Year Floodplain, see the 100-Year Floodplain link to understand what this means. Additionally, you can prepare for the adoption of new Flood Insurance Rate Maps by taking the steps below.

FEMA issued Preliminary Flood Insurance Rate Maps for this project in November 2016. The map viewers below have been updated with the preliminary map data. You can also view the Preliminary Flood Insurance Rate Map panels by visiting the Maps & Technical Reports page.
Note that any map information you see is in preliminary format—FEMA will open an official 90-Day Appeal and Comment Period (expected June 2017). In the meantime, the County Planning Department welcomes your questions.
