As the eastward expansion of Craney Island surfaces from the murky Elizabeth River waters, contractors offload scoop after scoop of fossilized oyster shells from barges at the facility in Portsmouth, Va. The shell is part of the environmental mitigation for the facility's eastward expansion, which also includes wetland creation and sediment remediation. Anchor Intro: Finding quality substrate for an oyster reef is becoming rather difficult, but thanks to an agreement between the Commonwealth of Virginia and the U.S. Army Corps of Engineers, Norfolk District, one project has all the shell it needs. Patrick Bloodgood has the story. Soundbites include Keith Lockwood - Chief, Technical Services Section, USACE and Jack Travelstead - Commissioner, Virginia Marine Resources Commission.
