Peyton Run at Longwood Knolls Stream Restoration Project (PC82-0006/PC9120/0327DP)

Project Update: May 25, 2021

The project is under construction with completion scheduled by summer 2022. The completion date is dependent upon the weather.

Project Background

The project includes a detention basin retrofit and stream restoration to Peyton Run. County staff identified the need for basin retrofit and channel restoration following public concerns about erosion. The project is also identified in the Pohick Creek Watershed Management Plan.

Project Description

Condition of the stream in March 2018.

The project is under construction with completion scheduled by summer 2022. The completion date is dependent upon the weather. The Peyton Run stream originates near the intersection of Stipp Street and Bestwicke Road and flows to detention basin 0327DP next to Lee Chapel Road. The project includes the restoration of a tributary that originates at Turnbuckle Drive and flows east until the channel joins the Peyton Run stream. One detention basin and approximately 2,841 feet of stream channel will be restored. This is a high priority project due to public safety concerns, the severity of erosion, the location in the headwaters of the Pohick Creek Watershed and the interest and support of the community.
