NORFOLK, Va. (June 17, 2014) – Keith Lockwood, Norfolk District’s Technical Support Section chief, marks a boundary stake of a new oyster reef being seeded with spat-on-shell to allow for easier monitoring of their survival rate. Last October, Corps contractor Precon Marine Inc. of Chesapeake, Va., began phase two of a 10-year, $70 million, and 411-acre environmental mitigation plan to offset ecological impacts associated with the Army Corps of Engineer’s Craney Island Eastward Expansion, or CIEE, project. Phase two involved the construction of six permanent sanctuary oyster reefs, totaling 16 acres. Through a special agreement with the Virginia Marine Resources Commission, Precon Marine Inc. used 39,000 cubic yards of fossil oyster shell dredged from the lower James River to build-up areas where historic reefs were once located. The layer of fossil shell will serve as the reef base throughout the proposed mitigation area. The reefs will incorporate knowledge and experience gained from other Corps oyster reef restoration and habitat projects in Virginia’s Great Wicomico, Rappahannock and Lynnhaven rivers, and Tangier and Pocomoke sounds. The project enters its final phase as the six oyster reefs are carefully hand-seeded with six million spat-on-shell oysters. The CIEE project, which is expanding Craney Island with dredged material fill that will serve as the base for a new port terminal, is expected to impact the bottom of the Elizabeth River. The project’s environmental mitigation plan uses a “landscape approach,” which allows all three-habitat elements – wetlands creation, oyster restoration and creation, and remediation of Elizabeth River bottom – to thrive and sustain each other. The Virginia Port Authority, partnering with the Corps, completed first phase of mitigation last November, with an 11-acre wetlands creation project at Paradise Creek Nature Park in Portsmouth, Va. The Elizabeth and Lafayette rivers benefit from the second ph
