Floodplain Mapping Projects

Lower Kansas Custom Watershed

The Lower Kansas Custom Watershed Floodplain Mapping update project will produce Base Level Engineering (BLE) floodplains for the entire custom watershed. They are beginning to be produced and should be available in Fall 2020. Enhanced data development is anticipated to begin in 2021 or 2022 for the areas that will undergo a regulatory update. We anticipate regulatory updates for Douglas and Jackson Counties, but Discovery meetings will be held to discuss where regulatory updates are needed. Brown and Nemaha Counties are being updated through separate county-wide projects. This website will be updated with relevant content as the project moves forward.
