The county is soliciting bids for this project. Construction is expected to begin in winter 2022.

Project Background

This project was identified in the Pohick Creek Watershed Management Plan for stream restoration and stabilization. It was placed in the county's Fiscal Year 2017 work plan as a result of maintenance issues related to Lake Royal.

Project Description

The project will restore more than 4,800 linear feet of natural channel and about 1,300 linear feet of outfall leading to it. The stream channel exhibits eroded and over-widened banks, head-cuts, and the potential for further bed and bank instability. Restoration objectives include stream stabilization, water quality improvement, aquatic and riparian habitat enhancement and reconnection of the channel to its floodplain. 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 
  • Reconnect the channel to its floodplain
  • Restore native trees and herbaceous planting to promote natural reforestation 
  • Develop a healthy ecosystem 
     

Project Location

The project in the Pohick Stream Valley Park, upstream of Lake Royal, on Fairfax County Park Authority property.

  • Creation of in-stream and riparian habitat for wildlife and development of a healthy ecosystem
  • Improvement of water quality through the removal of Nitrogen, Phosphorous and Total Suspended Solids

Project Timeline

Construction is expected to begin in FY 2022.

Project Cost and Funding Source

Stormwater projects are funded through the county Stormwater Service District.

Presentations to the Community

The goal of the stream restoration is to build an ecologically sound restoration that balances water quality benefits with riparian function and park user experience.
