Background/Discussion
The City of Council Bluffs owns or sponsors multiple levee segments which encompass the City Federal Levee System, providing flood protection from the Missouri River, Mosquito Creek, and Indian Creek. These levee systems are currently shown on FEMA floodplain maps as being accredited and are identified as providing protection from the 100-year flood or 1% annual chance flood event.
In order to maintain the level of protection identified on the FEMA Flood Insurance Rate Map, it is necessary to provide documentation to FEMA that complies with the requirements of 44 CFR 65.10. If the levees are not certified, they will be de-accredited and FEMA will begin the process of updating maps. Areas previously protected by the levees will be identified as flood-prone.
In order to meet the criteria for levee certification, improvements to each of the levee systems will be necessary. The purpose of the Geotechnical MR_3 and MR_4 projects are to resolve levee seepage and stability deficiencies. The project will construct large berms along the land side of the levee.
Public Works was successful is securing funding through the Economic Development Authority (EDA) Economic Adjustment Assistance disaster recovery program. The estimated cost for construction is $9,074,300. The EDA share is 80% of construction costs with a maximum contribution of $8,485,749. The City’s share will be funded by funds from the Iowa Flood Mitigation Program and Sales Tax Funds programmed for levee improvements.
