| | | | | | | | Description
Resolution authorizing the Mayor to execute an agreement with Barr Engineering Co. for engineering services in connection with Levee Certification Projects, Geotechnical MC_1, and MC_2. |
|
| | | | | | | | 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 MC_1 and MC_2 projects are to resolve levee seepage and stability deficiencies along Mosquito Creek. The scope may also incorporate the correction of any noted deficiencies in the project area from the latest USACE inspection.
The design engineer will be responsible for developing contract documents for construction that comply with USACE requirements while maintaining the existing level of flood protection. They will also assist with acquiring all necessary regulatory permits, and oversee bidding of the project. Construction engineering services may also be included during the construction phase.
The Engineer was selected based on their ability to provide the necessary services utilizing the selection criteria outlined in the Professional Services Policy. Statements of qualifications were solicited from eight engineering firms. One submittal was received and reviewed based on the team qualifications, past experience, project approach and understanding, and clarity, conciseness and organization of the proposal. Barr is a geotechnical expert with extensive expertise in levee design and USACE permitting, and an excellent fit for these projects.
This project was included in the FY24 CIP. 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. The use of bonds may also be investigated.
