Missoula Granite Floodplain Maps Updates
Missoula and Granite Counties are working with MT DNRC and FEMA to update and produce new Flood Insurance Rate Maps (FIRMS) for the Clark Fork River, Bitterroot River, Rock Creek, and Rock Creek Tributaries. Updated floodplain maps will depict the latest, most accurate flood risk data, and will eventually replace the existing floodplain maps which are based on data from the 1970s.

DNRC held project kickoff meetings on October 23rd with Missoula County and the City of Missoula. To view the slides that were presented click here.
