Mineral County Flood Maps Update

 Mineral County and the Town of Superior are working with the Federal Emergency Management Agency (FEMA) and Montana Department of Natural Resources and Conservation (DNRC) to update and produce new Flood Insurance Rate Maps for the Clark Fork River, the St. Regis River, and tributaries. Updated floodplain maps will depict the latest, most accurate flood risk data, and will eventually replace FEMA’s existing floodplain maps which are based on data from the 1970s.

New Flood Insurance Rate Maps from this project are not expected to be finalized for a while – the study information and maps need to go through a technical and public review process 

When finalized, the new maps could have effects on some property owners in mapped floodplains (see our FAQs page for more information).
