Arlington National Cemetery Millennium Expansion Plan

George Washington Memorial Parkway » Arlington National Cemetery Millennium Expansion Plan » Document List

As part of the project, the existing stream channels, which are currently severely degraded in some areas, would be restored and integrated into the overall project as a natural landscape amenity. Natural Channel Design (NCD) techniques would be utilized to restore the existing channels. By establishing stable channel geometry and reestablishing a floodplain connection, excessive bank and bed erosion can be arrested, in-stream habitat improved, and the downstream transport of pollutants reduced. Although ~890 trees would be removed, this impact was minimized during planning and an additional 600 trees and 500 shrubs will be planted to help
mitigate for this impact.
