Design under review for Piney Run stream restoration in Reston

Fairfax County is making progress on a stream restoration project at Lamplighter Way in Reston after receiving the needed land rights to move ahead with designing the project.

The project was identified by the county’s management plan for the Difficult Run watershed and a nomination by Reston Association, which owns the land.

With the project, the county will restore about 1,200 linear feet of natural stream channel between Lamplighter Way and Woodbrook Lane, extending downstream to Piney Run.

The stream channels are severely eroded and over-widened bank, leading to further bed and bank instability, according to the Fairfax County Department of Public Works and Environmental Services.

“Two sanitary sewer lines have been exposed by the erosion,” the department says on its project page. “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 county will hold two public meetings on the project next month. A virtual meeting is set for Thursday, Jan 4 at 7 p.m. and an in-person meeting is scheduled for Saturday, Jan. 6 at 10 a.m. Participants should meet at the park trail entrance at Center Harbor Road.

The project design is 65% complete, and plans are under review. Once the review is completed, the final design phase will begin. Construction is expected to begin in the winter of 2024.

The project costs $464,000.
