The Turkey Run @ Truro Subdivision Stream Restoration project in Fairfax County, VA restored 3,850 linear feet of stream channel and tributaries. The project improved stream morphology, removed an existing pedestrian bridge and replaced it along with six others, removed an existing trail and part of a parking lot, added materials to stabilize the stream bed and banks, controlled invasive species, and added structures to reduce erosion and improve habitat. The project is estimated to reduce phosphorus and nitrogen pollution and sediment entering Accotink Creek and the Potomac River annually.

Description:
The Turkey Run @ Truro Subdivision Stream Restoration project was substantially completed within budget on October 19, 2017. This
project included restoring approximately 3,850 linear feet of stream channel and tributaries. The Tributary of Turkey Run which drains
directly to Accotink Creek in the Accotink Creek watershed is located in the center of Fairfax County, Virginia and drains southeast to
Accotink Bay, then Gunston Cove and finally to the Tidal Potomac River. Restoration of the stream was achieved through the use of
natural channel design principles.
Project Overview:
• Restoring stream morphology and connectivity to the adjacent floodplain and riparian zone
• Removing one pedestrian bridge and replacing the existing six pedestrian bridges with six new pedestrian bridges
• Removing and replacing the existing trail and used part of the parking lot
• Place Reinforced Bed Mix material to stabilize the stream bed and banks
• Control invasive species
• Reduce erosion using in-stream grade control structures including: Rock Sill, Boulder Toe Protection, Buried Rock Toe, Riffle with
Log Sill, Step Pools, Boulder Clusters and Modified Cross Vanes with woody debris
• Create overbank wetland areas and install surface and buried woody debris to support habitat improvement
• The project reduces total phosphorus by 772.96 pounds per year; reduces total nitrogen by 1,661.55 pounds per year; and
removes 265,770.63 pounds of sediment per year from this tributary leading to Potomac River
