Floodplain Mapping Projects

Lower Republican Custom Watershed


The Lower Republican 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 Spring 2021. Enhanced data development is anticipated to begin in 2023 for the areas that will undergo a regulatory update. We anticipate regulatory updates for Republic County, but Discovery meetings will be held to discuss where regulatory updates are needed. This website will be updated with relevant content as the project moves forward.
