L575 Levee Restoration Information - UPDATED 6/8/19

Background: The L-575 Benton-Washington-McKissock-Buchanan-Atchison-Hamburg Levee System experienced significant damage during the 2019 Flood Event. This led to seven (7) breaches, along with substantial other damages, occurring throughout the Levee System.
Current Action: Two priority breaches that are impacting the I-29 corridor have been identified for initial repairs. These two construction contracts were awarded on 14 and 19 Apr 2019. The OSRT is also working an overall plan for rehabilitating the levee system. 
Next Steps:
  1. Provide an interim level of flood risk reduction at both initial breach repair locations.
  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.
