MCM was required to commission a sonar survey to locate the debris and develop a corrective action plan for removal. Terracon Consulting Engineers & Scientists conducted the survey, and C.J. Mahan Construction Company, LLC was retained for the underwater excavation. The removal operation required barges, cranes, and divers, with oversight from the Corps. The corrective measures were completed on October 20, 2021, and the Corps confirmed the successful resolution on January 26, 2022.
