Description Description of Work: Savannah Harbor Dredge Material Containment Area (DMCA) 12A parallels the north edge of the Savannah River Back River in Jasper County, South Carolina. The containment area, which is roughly 1150 acres in size, is one of nine confined dredge material containment areas used for dredging the Savannah River channel. To safely contain these materials the storage capacity of DMCA 12A needs to be increased and improvements to the water control outlets need to be made. The scope of work for this project consists of raising the crest elevation of the perimeter dike by as much as six feet, clearing the interior, and adding a 2 foot thick sand cap to the existing bird island in the western portion of the DMCA. Also included are repairs and modifications to the five existing weir/water control structures along the western dike, clearing and grubbing of an area along the DMCA exterior, and replacing the main entrance gate.
