Miles City’s new DFIRM maps took effect July 22, 2010. With this change, the floodplain encompasses a large part of Miles City with approximately 79% of structures currently being in the floodplain and approximately 5% of them within the floodway. This new change has caused a lot of citizens to purchase flood insurance or to have their property surveyed to see if they qualify for a Letter of Map Amendment (LOMA) which shows that their structure or property is outside of the floodplain. Many questions and concerns have been talked about and we would be more than happy to listen to your concerns or questions. Please use one of the contacts below.
