Lake Wa Con-Da Levee Restoration Information

Background: The Lake Wa Con-Da – Missouri River Right Bank Levee System was damaged during the 2019 Flood Event, leading to the Levee 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 Lake Wa Con-da levee repair project. The purpose of this rehabilitation project is to repair the levee system to its 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 levee 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.
 

Status Update:

08 November 2019 - The AECOM/URS design team is scheduled to submit the 60% levee repair design to the USACE team for review in mid-November.

24 October 2019 - The AECOM/URS design team anticipates submitting the 60% levee repair design to the USACE team for review in early November.

13 October 2019 - The AECOM/URS team is continuing their site investigation, drilling and survey, efforts.  The design team is expected to submit the 60% design plans in November.  Note: there was an error in the last update, the 60% design is due to the USACE team for review in November not October.

27 September 2019 – The design Contractor will submit the 60% levee repair design plans to the USACE team for technical review next week.

13 September 2019 – Design contract to repair the Lake Wa Con-Da levee system was awarded to URS Group, Inc. of Omaha, NE in the amount of $459,086.62 on 05 SEP 2019.  This design is currently scheduled to be complete by the end of the calendar year.

06 September 2019 – The team is finalizing the design contract with URS/AECOM and anticipates an award by the end of next week.  Following this award the team will setup an initial kick-off meeting and site visit, as well as develop an overall schedule for the design effort.

29 August 2019 – The design contract for Lake Wa Con-Da levee system will be awarded within the next two weeks.

23 August 2019 – Team continues engineering and design work on repairs for the Lake Wa Con-Da levee system. Upon completion of design by the end of 2019, a construction contract will be advertised and awarded to repair the system.

05 August 2019 – Engineering and Design (E&D) work continues for rehabilitating the Lake Wa Con-Da levee system.  The team is still anticipating to be done with the E&D process by the end of the calendar year.

08 July 2019 – Engineering and Design (E&D) work is ongoing for rehabilitating the Ames Diking project. The team is anticipating to be done with the E&D process by the end of the calendar year.

15 June 2019 – An initial site damage assessment and economic analysis has been completed.  From this initial assessment the USACE team has determined that there are damages to the levee system that are eligible for PL 84-99 Rehabilitation Assistance.  It was also noted by the assessment team that parts of the levee system couldn’t be assessed due to high water levels, and a follow-on damage assessment would be needed in the future.
