Flood Plain Map: Frequently Asked Questions

Preliminary Summary of Map Action (SOMA)

Representatives from the U.S. Department of Homeland Security’s Federal Emergency Management Agency (FEMA), in conjunction with Ohio Department of Natural Resources (ODNR) ask residents to review a recently completed preliminary Flood Insurance Study (FIS) and accompanying preliminary Flood Insurance Rate Maps (FIRMs).

The FIS and the FIRMs provide base flood information, delineate areas subject to significant flood hazards within the county, and offer information public officials may use when permitting development in the floodplain. The updated floodplain maps are limited to the portion of Montgomery county within the Little Miami River Watershed.

Once the maps become effective, they will be used by floodplain permit officials, builders and developers, lenders, realtors, insurance agents, and the general public to determine flood risk, develop mitigation measures, and encourage wise and responsible risk management decision-making.

Property owners, realtors, lenders and, insurance agents are urged to attend and take advantage of this opportunity to learn more about flood risk and hazard mitigation within their community.  

FEMA leads the nation in a risk-based, comprehensive emergency management system of preparedness, protection, response, recovery, and mitigation to reduce the loss of life and property and support a culture of readiness for all hazards, including natural disasters, acts of terrorism and other major incidents.
