NORFOLK, Va. - Norfolk District, U.S. Army Corps of Engineers’ contractors from Great Lakes Dredging and Dock Company use bulldozers to push sand dredged from the bottom of the Chesapeake Bay into place along Norfolk, Virginia’s Ocean View Beach. The sand is part of a $34.5 million project to reduce storm damage risk to infrastructure along a 7.3 mile stretch of waterfront, which is susceptible to damage during costal storms. Once complete, the beach will be 60 feet wide and slope up to 5 feet above mean low water.
