The City of Yankton is 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 FEMA. 

If a community adopts and enforces a floodplain management ordinance to reduce flood risks, the NFIP in turn makes flood insurance available within the community as a financial protection against flood losses. 

The current Flood Insurance Rate Maps and Flood Insurance Study for the City of Yankton are dated July 6, 2010.  Copies may be obtained through the FEMA Map Service Center or to search by address use FEMA's National Flood Hazard Layer.

Development in the floodplain requires a Floodplain Development Permit.  Development means any man-made change to improved or unimproved real estate, including but not limited to buildings or other structures, mining, dredging, filling, grading, paving, excavation or drilling operations or storage of equipment or materials.  Some projects located in a special flood hazard area might still require a floodplain development permit even if exempt from a building permit 

The City of Yankton has issued General Floodplain Development Permit for some minor development and routine maintenance activities.  This includes only those projects and uses that have been determined to have minimal or no impact on flood hazards.  Please note that while some activities do not require an individual floodplain development permit, they may require notice.  If in doubt please contact the Community and Economic Development Department before you begin your project.
