On Dec. 10, 2010 the Norfolk District entered into an interagency agreement with the National Park Service to perform work to repair and stabilize shoreline of the York River at the Colonial National Historic Park in Yorktown, Va.
Work includes performing topographic and hydrographic surveys, subsurface investigations consisting of collecting and analyzing subsurface soil samples, designing the project, gathering required environmental permits, performing cost estimates and using industry partners to perform the repair and stabilization work.
The project is using a combination of stabilization structures and marsh protection measures to protect portions of the Colonial Parkway and Yorktown Battlefield, the site of the final siege of the American Revolution, from the York River, which has severely eroded its shoreline in the area over the past 50 years
Construction crews are working on the first 800 linear feet this fiscal year. A second interagency agreement is in the works to complete the remaining four miles of protection.
