The Lower Middle Arkansas Custom Watershed Floodplain Mapping update project produced Base Level Engineering (BLE) floodplains for the entire custom watershed. Enhanced data development for regulatory updates began for Harvey, McPherson, and Sedgwick Counties in 2021, and it is anticipated to begin in 2022 and 2023 for Reno and Barton Counties, respectively. This website will be updated with relevant content as the project moves forward. The Kickoff Meeting was held virtually on October 27, 2020, and the Discovery Meetings were held January 12 & 13, 2021. The presentation slides are located below.
