The U.S. Army Corps of Engineers, Omaha District, in partnership with Union County, South Dakota, will host a public open house for the Lower Big Sioux River Flood Risk Management Feasibility Study on Thursday, Oct. 22, 2026, from 6-7 p.m. at the North Sioux City Community Hall, 205 Sodrac Drive, North Sioux City, South Dakota.
The feasibility study is in its early stages, and no construction project or flood risk management measure has been selected or approved. USACE and Union County are beginning the process of evaluating existing flood risks along the lower Big Sioux River and identifying potential opportunities to reduce those risks.
The open house is intended to introduce the study to the community, explain the feasibility study process, and provide an opportunity for the public to ask initial questions and speak directly with members of the study team.
