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.

Current Action: A priority breach impacting the I-29 and Hwy 34 corridor has been identified for initial repairs.  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.

Next Steps:

  1. Increase the interim level of flood risk management at the initial breach repair location.
  2. Conduct physical damage assessment when water levels recede and the levees are accessible
  3. Design and construct levee rehabilitation to authorized level of flood risk management.

Status Updates:

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.
