Flag Run at Elgar Street Stream Restoration

Project Background

Present condition of the stream to be restored.
Present condition of the stream to be restored.

This project was identified in the Accotink Creek Watershed Management Plan for stream restoration and stabilization activities. It was placed in the county's Fiscal Year 2016 work plan as a result of severe erosion.

Project Description

The project will restore about 2,900 linear feet of natural stream channel. The stream channel exhibits severely eroded and over-widened banks, head-cuts and the potential for further bed and bank instability. This project is part of larger efforts to restore many of Fairfax County’s degraded streams while improving overall water quality and the condition of the Chesapeake Bay.
The primary goals of the restoration are: 

  • Stabilize the channel and prevent future erosion and degradation along the stream 
  • Improve water quality through the removal of nutrients (nitrogen and phosphorous) and sediment
  • Create a healthy ecosystem by restoring the channel and planting native trees and herbaceous plants 

Project Location

The project is located on public land east of Juliet Street, extending downstream through Flag Run Park to I-495.

Project Benefits

  • Improved water quality
  • Restoration of the ecological function of the stream corridor
  • Creation of in-stream and riparian habitat for wildlife

Project Phase

The project is under construction.

Project Timeline

The project design is complete. Construction started in summer 2019 and may extend through winter 2020. 

What to Expect

The project will require the use of heavy construction equipment. Dump trucks will deliver materials to the construction entrances at Elgar and Dunston Streets. Timber mat roads will be built through the stream valley to transport equipment and materials and protect tree roots. Some trees will be removed either because they are falling into the channel or to gain access for construction.

Project Cost and Funding Source

Stormwater projects are funded through the county Stormwater Service District.

Presentations to the Community

The project will restore about 2,900 linear feet of the channel to stabilize the banks and prevent future erosion. A healthy ecosystem will be created by installing native trees and herbaceous plants.
