Union County signs agreement with U.S. Army Corps to join Lower Big Sioux River flood study; adds two structures to five‑year plan

Union County commissioners voted July 7 to join a U.S. Army Corps of Engineers study of flood risk on the Lower Big Sioux River and to amend the county's five‑year plan to include two structures so the county may apply for federal hazard‑mitigation funds.

Representatives from the City of North Sioux City and Dakota Dunes attended the discussion on the cost‑share agreement tied to the study. Commissioner Dailey moved to approve signing the agreement between the Department of the Army and Union County; Commissioner Kimmel seconded and the motion carried.

Separately, the board approved a resolution (motion by Dailey, seconded by Ustad) to add Structure #64-040-037 and Structure #64-049-179 to the county's 2027–2031 Five‑Year Plan, a step the minutes say is needed so Union County can apply for a local federal grant this fall. The additions were recorded as carried.

The actions formalize Union County's participation in the Corps-led study and position the county to seek grant support for mitigation or repairs tied to the identified structures. The minutes do not list specific dollar commitments by the county for cost share or project timelines.
