River Bend Stream & Outfall Restoration Project

News and Announcements

As work continues on the project, residents should be aware that from March 25 through Friday March 29, 2024, passersby may experience increased construction traffic along Algonkian Parkway as the contractor removes debris from the Riverbend Stream Restoration project site. Drivers should exercise increased awareness in this area and pay attention to traffic flaggers as needed. Additionally, pedestrians and bicyclers should follow the detour signs and cross Algonkian Parkway at the traffic intersections. 

Project Progress: February and March 2024

The stream, a Potomac River tributary, flows between River Bend Middle and Potomac Falls High schools through property owned by the CountrySide Proprietary. The restoration project area is on the north side of Algonkian Parkway.

Work continues on the River Bend Stream and Outfall Restoration Project with nearly 10 percent of the work completed and considerable progress made across the entire project site. Crews have cleared the project area, meaning work can continue through the Northern Long-Eared Bat roosting season. No trees will be cut during the typical roosting window of April 1 through November 14.

This photo shows the toe wood that has been installed. Toe wood incorporates native woody material into a submerged undercut bank to replicate natural streambanks. The toe wood comes from trees that were cleared as part of the project.

The photo illustrates the use of a riffle, which allows allow water to bubble to help oxygenate the stream and provide habitat. The black cloth at the end of the rocks (cobbles) is the log sill. This log is from a tree from the site and the log sill helps to stabilize the bed and channel as well as provide habitat for macroinvertebrates.


About the Project 

The stream restoration project in the CountrySide area of Loudoun County is intended to increase animal habitat, improve local water quality and reduce pollutants and sediments into the Chesapeake Bay watershed. The stream, a Potomac River tributary, flows between River Bend Middle and Potomac Falls High schools through property owned by the CountrySide Proprietary. The restoration project area is on the north side of Algonkian Parkway. 

Work began in October 2023. The two-year project will require the closure of the pedestrian path north of Algonkian Parkway between Rutherford Circle and Cedarhurst Drive. A detour will guide pedestrians to and from an alternate route on the south side of Algonkian Parkway.

Project Details

The work will restore 3,125 linear feet of the stream and reintroduce native species, resulting in the planting of approximately: 

  • 600 trees. 
  • 6,000 live stakes. Live stakes are stem cuttings inserted directly into the stream bank; the developing root networks help reduce soil loss. 
  • 5,000 sage and rush grass plugs.  

Riparian and upland seeding along and above the banks of the stream also will be included. 

The project supports state and federal requirements to reduce pollutants into the Chesapeake Bay from local streams and is estimated to:

  • Eliminate more than 200 pounds of phosphorus per year. 
  • Eliminate more than 500 pounds of nitrogen per year. 
  • Prevent more than 130,000 pounds of total suspended solids, such as sediment or particles that do not dissolve in water, from reaching the Potomac.
