The Town of Mount Pleasant has engaged ATM to study the fate of dredge material placement on Crab Bank in Charleston Harbor. The relic spoil island, near the mouth of Shem Creek, has been eroding for decades to the point that only a small area of upland remains. As part of the deepening of Charleston Harbor, the US Army Corps of Engineers planned a beneficial use placement to dispose of more than 600,000 cubic yards of dredge material from the channel deepening to rebuild Crab Bank.

While everyone (agencies, Town and ATM) supports the recreation of seabird habitat, placement of such a large amount of dredge material warrants a study to determine the initial and long-term movement of the material once it is placed. There are potential impacts from the placement of this material to the Town’s natural resource of Shem Creek that should be evaluated. ATM will apply numerical modeling efforts to forecast material movement so that the Town can more fully understand the consequences of placement of the dredged material. Read full article.
