Release Date Release Number
Release Date:
June 16, 2021

DENVER –Flood insurance rate map updates for Deuel County, South Dakota are nearing completion. The new maps will provide unincorporated Deuel County and the Cities of Clear lake and Gary with more accurate flood risk information that can help local officials and residents make informed decisions about reducing flood risks and purchasing flood insurance.

The mapping project is part of a nationwide effort led by FEMA to increase local knowledge of flood risks and support actions to address and reduce those risks.

Before new flood insurance rate maps become effective, there is a 90-day appeal period during which local residents and business owners can provide additional data for consideration before the maps are final. This appeal period starts on June 23, 2021 and ends September 21, 2021.

Officials encourage residents and business owners to review the proposed flood insurance rate maps to learn about flood risks, potential future flood insurance requirements, and any concerns or questions about the information provided.

Appeal packages may be submitted during the 90-day appeal period. The sole basis of the appeal must include the possession of knowledge or information indicating that the proposed flood hazard determinations are scientifically and/or technically incorrect.

Preliminary mapping may be viewed on FEMA’s Map Service Center by visiting For questions, please contact your local floodplain administrator.
