At the beginning of the 20th century, the U.S. Federal Flood Control Act was characterized by a low budget levee only policy and prioritized the economic development of river basins. However, the validity of levee only projects was denied at the time of the Great Mississippi River Flood in 1927, and the comprehensive river project was considered to play an important role in flood control. As the federal fiscal burden increased due to large-scale federal river improvements, there was a demand to raise local cost contribution in order to reduce inefficient public works. As a result, federal and local cost-sharing was influenced by political dealings, economic conditions, and the conflict over authority between government agencies. During the postwar period, a uniform cost-sharing bill was submitted to Congress in order to modify the inconsistent cost-sharing system. A fixed burden ratio came to be defined in the Water Resources Development Act of 1986.
