In Cincinnati, the Army Corps of Engineers plans to institute the Mill Creek Flood Control Project, channelizing a 17.4-mile stream in an effort that will cost at least $340 million and require upkeep costs of $800,000 a year. The original estimate was $32 million.

However, Mill Creek damage payments by the National Flood Insurance Program from 1978 through 1990 came to less than $300,000. In 1959, a storm caused $3 million in damage, much of which was caused by factors unrelated to flood, including landslides and high winds.
