Floodplain Management

Douglas County is a participant in the National Flood Insurance Program (NFIP) administered by the Federal Emergency Management Agency (FEMA). This program provides subsidized flood insurance for all property owners, provided that the local government institutes adequate land use and development control measures for preventing and reducing property damage from flooding. In addition, Douglas County must ensure that projects within the floodplain comply with FEMA regulations and the Douglas County Zoning and Land Use Regulations.

Douglas County is in the process of obtaining new Floodplain maps from KDA-DWR/FEMA. We are expecting to receive these updates maps by mid-2023. Once Zoning and Codes has more information, we will be mailing property owners who we believe will be impacted. 

Understanding where floodplain exists is the first step for all property owners, developers, and prospective buyers to make informed decisions. Click any of the links below to discover where the floodplain exists in relation to your property:
