Beneficial use of dredged sediment
Savannah Estuary (Georgia)
In March 2014, the U.S. Army Corps of Engineers (USACE, Savannah District) created an eight acre bird island within the Savannah Harbor Dredged Material Containment Area (DMCA) as mitigation for routine operations and maintenance of the Savannah Harbor. The island was one part of a $5.3 million dike raising and improvement projects. Construction began in September 2012 and finished in October 2013. Around 160,000 yrds3 (122,328 m3) were used to create the bird island which was topped with an additional 36,000 yrds3 (27,523 m3) of coarse sand as a two-foot layer that provides better nesting habitat for shorebirds and slows the growth of plants that interfere with the shorebird nesting. On completion the island was surrounded with impounded with water pumped into the disposal area.
