Resolution accepting the bid of Valley Corporation for Levee Certification Project, Geotechnical MR_6.  Project # PW23-06A

On July 25, 2024 bids were received through the City bidding software Ion Wave.  Attached is a summary of the bids.

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_6 project is to resolve seepage deficiencies along the Missouri River.  The project will construct large berms along the land side of the levee.

Both the Base Bid and Alternate Bid must be awarded in order to complete the entire project scope.  The bids were separated to facilitate tracking of unit price items associated with separate permit approvals.

This project was included in the FY23/FY24 CIP and construction costs will be paid with GO Bonds programmed for levee improvements and Iowa Flood Mitigation Program funds.  The original project budget was $16M.

Approval of this resolution to award the project to Valley Corporation.  This project will improve the levee system to meet the criteria necessary for certification.
