The City is the local sponsor of the Council Bluffs Levee System, and as such, it is responsible for operation and maintenance. Performing regular inspections of the drainage structure pipes within the levee system is one of the responsibilities.
The most recent inspections of the drainage structures occurred in two phases. Most were completed in 2017, with a few on hold due to excessive debris in the pipes. Flooding in 2018 and 2019 caused further delays. The remaining inspections were completed in 2021.
To comply with USACE requirements, this project will undertake a system-wide inspection program that will result in an inspection report and overall rating for each levee drainage structure within the levee system.
The scope of the project includes over 21,000 linear feet of inspection and associated cleaning for gravity storm sewer pipes and boxes, and force main storm sewer pipes, with various diameters and lengths.
Additive bid items were included to inspect other structures within the levee right-of-way, which have not been previously assessed. It is recommended that Additive 3 be included when awarding this project. This adds the inspection of the IDNR outfall pipe to Lake Manawa which also crosses through the East Manawa property that the City recently acquired for development.
These inspections, with subsequent ratings, allow the Council Bluffs Levee System to remain active in the USACE PL84-99 levee program. By participating in the program, USACE will assist with flood fight efforts during a high water event, and provide restoration to the levee system if damages occur during the flood.
The project was added to the FY23 CIP and will be paid from levee improvement program funding. It is scheduled to be complete by December 2023.

| | | | | | | | Recommendation
Approval of this resolution. This project is necessary to meet the 5-year inspection requirements of the USACE PL84-99 program and supports the City’s levee accreditation efforts.
