L611-614 Levee Restoration Information

Background: The L-611-614 Missouri River Left Bank and Upper Pony Creek Ditch Levee System experienced significant damage during the 2019 Flood Event.  This led to three (3) breaches, along with substantial other damages, occurring throughout the Levee System.This construction contract was awarded on 26 Apr 2019. These initial repairs are directed at stopping the flow from the Missouri River into the area behind the levee system and providing an incremental level of flood risk management. Follow-on actions to further repair the levee system and provide additional flood risk management are being coordinated within the PL 84-99 program.
 
Current Action: The team is preparing for the final inspection of the inlet breach site on 03 September 2019. The scope of work for the outlet breach is still being determined.

Status Updates:

06 September 2019 – The final inspection for the initial breach repair efforts was conducted on 03 September 2019 and the contractor is now preparing to de-mobilize from the site.  Proposals have been received on the contract to complete follow-on interim repair efforts and it is anticipated that this contract will be awarded by early next week.  These efforts will focus on repairs other critical sections along the levee system as well as the outlet breach on the southern end of the levee system.

29 August 2019 – The final inspection is scheduled for 03 September 2019.  

23 August 2019 – All work is scheduled to be substantially complete by 23 August with minor work remaining the week of 26 August.  

13 August 2019 – Construction of the clay levee, including mod work to increase the height of the clay levee to match the existing adjacent levee height is  approximately 95% complete. A site walk was conducted on 09 August 2019 in order to review the scope of work with the contractors prior to opening the contract to bids.

31 July 2019 – The Contractor has completed sand berm construction. Clay levee construction commenced on 15 July 2019. The Government is in the process of modifying the contract to increase the design height of the clay levee to match the existing adjacent levee height. All work is scheduled to be complete by mid-August. The follow-on interim repair contract is currently awaiting the award of the R-616-613/R-613 Contract, so that it can be advertised to the contractor pool.

22 July 2019 – Statement of work is being finalized and then will await award of the R616-613 contract.

08 July 2019 The Contractor continues to widen the sand berm closure pad in preparation for the clay levee to be built on top of the sand berm pad. Clay levee construction will likely start later this week.

20 June 2019 – The Contractor continues to widen the sand berm closure pad in preparation for the clay levee to be built on top of the sand berm pad. Clay levee construction will likely start in late June or early July 2019.

12 June 2019 – The priority breach was initially closed on 12 June 2019.  This closure stops inflows through the breach and will allow for follow-on construction activities to further increase the level of flood risk management provided by the repaired levee section.

11 June 2019 – Super saturated conditions at the breach location directly west of the mouth of the Platte River required a redesign of the haul road. A significant portion of the initially constructed sand berm was inundated and eroded during the late May high water event. Since that event, the remaining sand berm has been raised to a higher elevation to better protect and ensure the stability of the repair. The contractor began extending the sand berm toward the southern tie-in point on 3 June 2019 and is anticipated to have the breach initially closed within the next week.
