Fairfax County Public Works and Environmental Services has started construction on a project to improve a watershed in Kings Park West near Burke by restoring eroded stream banks.

Part of a plan approved over a decade ago, the Shanes Creek restoration seeks to stabilize the channel and prevent future erosion and degradation along the stream. It will also reconnect the channel to its floodplain and restore native trees and herbaceous planting to promote natural reforestation and a healthy ecosystem, according to a project page.

“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 project page says, noting that construction work began on April 13.

The project requires closures of the trail network leading from nearby residential neighborhoods into Royal Lake Park, which is just to the south of the creek.

“The existing parkland trails within the project boundaries will be closed for the duration of the project to ensure public and worker safety,” the Fairfax County Park Authority said. “Active construction is anticipated to be completed by winter 2023.”

According to DPWES, work on the stream will start at Roberts Road, and crews have begun to set up fencing, “trail closed” signs, and other equipment. Trail closures will depend on where construction is underway.

“We are attempting to keep as many open as we can while construction is occurring, so there is not a clear map of what is open now [versus what] will be later,” DPWES spokesperson Sharon North said by email. “…We are working to install the fence and signs as we can.  The limits of disturbance will be well marked before construction of the stream starts.”

The Board of Supervisors approved a watershed management plan for the Pohick Creek watershed in 2010. The plan called for stream restoration efforts to re-establish those waterways that would help minimize erosion, including planting vegetation to stabilize and protect stream banks.
