The Dead Run at Dominican Retreat - Segment 1 Stream Restoration project restored approximately 2,000 linear feet of Dead Run in Fairfax County, Virginia. The project used natural channel design principles to restore stream morphology, replace bridges and culverts, control invasive species, and add in-stream structures to reduce erosion. It was completed ahead of schedule and on budget in June 2017. The restoration aims to improve water quality and habitat in the tributary of Dead Run that flows into the Potomac River.

Description:
The Dead Run at Dominican Retreat –Segment 1 Stream Restoration project was substantially completed on budget and ahead of
schedule on June 27, 2017. The project restored approximately 2000 linear feet of the Tributary of Dead Run which drains directly to
the Potomac River in Mclean, Virginia. 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
• Replace the three existing Pedestrian Bridges with two new Pedestrian Bridges and one Step Stone Crossing
• Replace the existing Yard Inlet with a new Manhole Structure with a base section 60” in diameter
• Replace the abandoned 24”RCP with new 105 feet of 24”x 38” elliptical RCP associated with well stabilized outfall channel
• Place Reinforced Bed Mix material to stabilize the stream bed and banks
• Control Invasive Species
• Replace the disturbed/damaged Trails with Wood Chip Trail to match pre-construction conditions
• 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
• Create overbank wetland areas and install surface and buried woody debris to support habitat improvement
• The project reduces total phosphorus by 141 pounds per year; reduces total nitrogen by 128 pounds per year; and removes 42
tons of sediment per year from this tributary leading to Potomac River
• Landscaping (to be accomplished in the fall 2017 planting season)
