Missouri River Levee Setbacks

After the 2011 Missouri river Flood event, the sponsors of Levee L-575 pursued the Nonstructural alternative (NSA) of a levee setback under the U.S. Army Corps of Engineers Disaster Operations Public Law 84-99 program. This setback relocated a segment of the levee from its current alignment to a location farther back from the banks. This reconnected part of the Missouri River to its floodplain and created habitat for fish and native vegetation. This setback also reduces erosion, increases flood conveyance, and increases resiliency of the levee system. This project reduces overall maintenance, repair, replacement and rehabilitation costs.
