Despite another major flood in 1951, Congress did not agree to a flood control plan until 1962, when it authorized a project that included levees and a flood control dam on the Kickapoo River upstream of Soldiers Grove near La Farge, Wisconsin. Owing largely to environmental concerns, however, construction of the proposed dam was halted partway through construction in 1975 and never finished. In the meantime, a 1974 floodplain zoning ordinance had already taken effect in Soldiers Grove, prohibiting new construction and severely limiting maintenance options near the river and crippling the village's downtown area. Although a levee proposed by the U.S. Corps of Engineers in 1975 would have lessened the restrictions, the village rejected the plan because of costs. While the downtown property was worth approximately $1 million, a levee to protect it would have required $3.5 million to construct and an additional $10,000 a year afterward for annual maintenance.
