City of Yankton - Floodplain

FEMA Floodplain AdoptionThe City of Yankton is an active participant in the National Flood Insurance Program (NFIP) administered by the Federal Emergency Management Agency (FEMA). Participation in the NFIP is voluntary and is based on an agreement between the community and the federal government. If a community adopts and enforces a floodplain management ordinance to reduce flood risks, the federal government in turn makes flood insurance available within the community as a financial protection against flood losses.

On July 6, 2010, as part of FEMA’s Map Modernization Program, the City of Yankton enacted FEMA’s July 6, 2010 Digital Flood Insurance Rate Map (DFIRM) and Study. *The July 6, 2010 Digital Flood Insurance Maps replace the 1980 Flood Insurance Maps and Study.

Below is a summary of the differences between the 1980 Flood Insurance Rate Maps and the adopted July 6, 2010 Insurance Rate Map and Study.
