The county is soliciting bids for this project. Construction is expected to begin in winter 2022.
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.
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
The project in the Pohick Stream Valley Park, upstream of Lake Royal, on Fairfax County Park Authority property.
Reduction of high sediment loads to Lake Royal
Restoration of the ecological function of the stream corridor
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
