PORTSMOUTH, Va. – Cranes at the Craney Island Dredged Material Management Area, or CIDMMA, here are removing fossil shell from a barge into a dump truck. Once the thousands of cubic yards of shell dredged from Tribell Shoal in the James River is sifted it will be stored here temporarily. On July 8, the site began storing the shell, which will be used for the construction of six oyster reefs for the Craney Island Eastward Expansion project. Construction of the $3.6 million environmental restoration project is set to begin in August of this year. Reefs will be built in Hoffler Creek, Baines Creek, Blows Creek, the Lafayette River and two in Gilligan’s Creek.
