What is Craney Island?
What is often referred to as “Craney Island” is the Craney Island Dredge Material Management Area (CIDMMA). CIDMMA is a man-made 2500-acre dredge material placement site in Portsmouth, Virginia located at the confluence of the Elizabeth and James Rivers. CIDMMA was authorized by the U.S. Congress in 1946. Construction of CIDMMA was completed in 1958. The site receives navigation related dredge material from private and public dredging projects bounded by the Hampton Roads Bridge Tunnel on the west, to the James River on the north, and the entire Elizabeth and Nanesmond Rivers. The United States Army Corps of Engineers (USACE) owns and operates the CIDMMA.
