Gallatin Mapping Updates

Gallatin Website Banner


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 the Summer 2019 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 show 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 in Summer 2018). In the meantime, the County Planning Department welcomes your questions.

FEMA 90-Day Appeal and Comment Period


We expect for the official FEMA 90-Day Appeal and Comment period to start in Summer 2018 (exact dates TBD). At that time, you will have the opportunity to submit an official Appeal or Comment about the proposed Flood Insurance Rate Map changes with FEMA. Check back here for useful links and updated information on the exact dates of the 90-Day Appeal and Comment Period.
 
 


Public Meetings Held


Gallatin County, the City of Bozeman, Montana DNRC, and FEMA hosted two Public Open Houses in January 2017 to review the Preliminary Flood Insurance Rate Maps and talk with property owners one-on-one about the proposed floodplain map changes. Please check back for updates on future meetings.   

 


Join our email list to stay informed on project updates


The process of publicly reviewing and adopting new Flood Insurance Rate Maps will take a couple years. We will keep affected and concerned property owners informed as best we can during this process. If you would like to stay informed on the Flood Insurance Rate Map adoption process via email, please opt in to our email list on the right side of the page. 
 


Come back for more information


We will update this website with new, relevant information as the Gallatin County Flood Insurance Rate Map adoption process progresses. Also, visit the links on the right side of the page, including our Floodplain FAQs link, for more in-depth information.
 


Know your property's flood risk


Flood Insurance Rate Maps indicate areas of increased flood risk. Once this project is complete, Gallatin County Flood Insurance Rate Maps will provide more accurate, current, and detailed data and mapping of flood risk areas.
