| | | | | | | | Description
Resolution approving the plans, specifications, form of contract, and cost estimate for the Levee Certification Project, Geotechnical MR_8. Project # PW22-06B |
|
| | | | | | | | 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_8 project is to resolve seepage deficiencies along the Missouri River. The project will construct large berms along the land side of the levee.
• This project was included in the FY22 CIP and has a revised estimate of $2,500,000 for construction. The project costs will be paid from levee improvement program funding including the Iowa Flood Mitigation Program and Local Option Sales Tax funds programmed for levee improvements.
