Old Robin Combined Utility Rehab Project

A project starting in June will rehabilitate sanitary and stormwater infrastructure near the terminus of Old Robin Street (formerly Traveler Street) in the Mosby Woods neighborhood.

The project includes executing four rehabilitation tasks simultaneously:

1. The exposed sanitary sewer pipe crosses a tributary within Dale Lestina Park. The pipe will be encased in concrete to protect it from debris during storms.
2. Eroded streambanks near the encasement will be regraded.
3. Two stormwater outfall channels will be restored.
4. Revegetating the site with “super clumps” to enhance plant survival post-construction.

City staff and contractors will be active in the area from June 23 through the end of July. This operation may require short-term lane closures and parking restrictions in the Old Robin Street cul-de-sac.

The city council on May 13 awarded the $327K contract to Environmental Quality Resources, LLC, a firm that specializes in in-stream rehabilitation work. The outfall restorations received a Stormwater Local Assistance Fund grant to support TMDL crediting for the Chesapeake Bay.

Impacts on the forest and surrounding community will be minimized. Access to the site was carefully planned. Timber mats will be laid down to reduce the impact on vegetation. The project team collaborated with the city’s urban forester to preserve as many trees as possible.

If you experience any disturbances to sewer flow, please contact the Department of Public Works Wastewater Division at 703-385-7915.
