Resolution accepting the work of Neuvirth Construction, Inc. as complete and authorizing release of the retainage after 30 days if no claims are filed in connection with the Levee Certification Project, Geotechnical MR_2.  Project # PW16-06A.

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_2 project was to resolve seepage deficiencies along the Missouri River levee.  The project modified the existing relief well system with piping to lower the head of each well, improved a drainage channel, and provided a sump structure for ground water pumping.

The FY16 CIP included $1,695,000 funded by the Iowa Flood Mitigation Program and $3,305,000 in Sales Tax Funds programmed for levee improvements.  The budget for this project was $960,000.

Contractor did not complete the project on time and liquidated damages in the amount of $17,250 were assessed; the liquidated damages are currently subject to litigation pending in Pottawattamie County District Court.

Approval of this resolution.
