Des Moines Metropolitan Area
This project is a proposal to raise portions of Des Moines I, II and III levee systems, and to raise and relocate portions of the Southeast Des Moines levee system, which is part of the Lake Red Rock Remedial Works. The proposed levee raises range from approximately 6 inches to 2.0 feet. The purpose of the proposed levee raise is to comply with FEMA’s levee certification requirements.
In May 2017, the city of Des Moines submitted an initial comprehensive plan that described all of the proposed levee modifications and associated mitigation actions the City is requesting Section 408 permission for. The Rock Island District reviewed this plan and approved it on July 20, 2018. The Rock Island District also entered into a cultural programmatic agreement with the City and the State Historical Preservation Office to ensure compliance with Section 106 of the National Historic Preservation Act.
Following the approval of this conceptual plan the city will submit detailed plans for each levee system for final review and approval. The city has identified eight phases (A-H) for submittal of detailed plans. Phase A and B 60% plans were submitted by the city for Corps review and were approved in 2019. Amphitheater portion of Phase A 95% plans were submitted by the city for Corps review in August 2019.
