Richland County Flood Maps Update
Richland County is currently working with the Federal Emergency Management Agency (FEMA) and the Montana Department of Natural Resources and Conservation (DNRC) to update floodplain maps for the Yellowstone River. New 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 1978.
There will be insurance and development regulation implications for structures going into and coming out of the 100-Year Floodplain when the maps become effective (expected late 2018). Property owners can educate themselves about the adoption of the new floodplain maps by taking the steps below.
The Preliminary maps were released February 22, 2017. FEMA will open an official later this year (expected September 2017) 90-Day Comment and Appeal Period Fact Sheet click here for the Appeal & Comment form.
