Arlington National Cemetery Millennium Expansion Plan
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.
