Council Bluffs Levee Restoration Information

Background: The L-624 Missouri River Left Bank, Indian Creek Left Bank, and Mosquito Creek Right Bank, L-627 Missouri River Left Bank and Indian Creek Right Bank, and L-627-624-611-614 Mosquito Creek and Upper Pony Creek Levee Systems that provide flood risk management to the City of Council Bluffs IA were damaged during the 2019 Flood Event, leading to the Project Sponsor submitting a Public Law (PL) 84-99 Rehabilitation Assistance request to the US Army Corps of Engineers – Omaha District.

Current Action: Design funding has been received to begin work on the levee repair project, with initial damages eligible for rehabilitation assistance only being found on the L-627 levee system.  The purpose of this rehabilitation project is to repair the levee system to the authorized level of flood risk management.

Next Steps:

  1. Complete the Engineering and Design process.
  2. Advertise and award the levee repair construction contract.
  3. Repair the system to its authorized level of flood risk management.
  4. Conduct a follow-on damage assessment of the levee once the Missouri River water levels recede to determine if there is more damage to the levee system that is eligible for PL 84-99 Rehabilitation Assistance.
