Public Works and Environmental Services Alert:
This project was identified in the Difficult Run Watershed Management Plan for stream restoration and stabilization activities and was nominated by the Reston Association. It was placed in the county's Fiscal Year 2020 work plan due to severe erosion and exposed sanitary sewer lines.
The project will restore about 1,200 linear feet of natural stream channel. The stream channel exhibits severely eroded and over-widened banks, and there is the potential for further bed and bank instability. Two sanitary sewer lines have been exposed by the erosion. 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:
The project is located on Reston Association Property between Lamplighter Way and Woodbrook Lane and extends downstream to the Piney Run stream.
The project is in the design phase. The concept plan was submitted in November 2021. The county is working to obtain the necessary easements before moving forward with the next design phase.
