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.

It appears the outfall grant funding and sewage line encasement are being used for justifying the real intent: stream re-imagining and avoiding public debate after the Stafford Drive fiasco. This plan has an access point, a staging/laydown/stockpile location, removal of a bridge, and cutting down over 30 trees, etc.; none of which are necessary for an outfall or encasing the sewage line with concrete, which would need little more than a Bobcat-sized excavator. My opinion: There is no peril to persons or property. This is another expensive overreach project driven by staff that will probably cause more ecological damage than benefit. on Facebook Share Where does this project show up in the Fairfax City budgets?

    Thank you for your question. The Old Robin Combined Utility Rehab Project is comprised of multiple rehab projects occurring within the same limits of disturbance. The project is split between three sources of funding: two project accounts in the FY2025 adopted budget and Stormwater Local Assistance Fund (SLAF) Grants. The project accounts are listed below, and full descriptions are available in the budget document. 

    City of Fairfax, Virginia - Adopted Capital Improvement Program FY 2025 to 2029

    Name: Wastewater Stream Pipe Encasement Project

    Project #: 403-435120-580451

    This account includes the funding for the encasement and stream bank stabilization

     

    City of Fairfax, Virginia - Adopted Capital Improvement Program FY 2025 to 2029

    Name: TMDL Action Plans

    Project #: 555-438130-580520

    This account includes the funding for the two adjacent outfall restorations that also received SLAF funding. (This line item is present on page 296).

     

    All activities for this project are required maintenance to maintain our sanitary sewer and stormwater utility infrastructure. The stream bank stabilization required to support the sanitary sewer encasement does fall within the bounds of priority project #4; however, this is only a short section immediately adjacent to the encasement. This portion of bank stabilization is required to ensure the long-term structural integrity of the sewer encasement as it ties directly into the stream banks on either side. Constructing the sewer encasement without also stabilizing the adjacent stream banks would result in further erosion at the encasement site, further exposing the sanitary sewer pipe. 

    This project is very different from the Stafford drive stream restoration in size, scope, and purpose. The purpose of this project is to conduct maintenance on our sanitary sewer service line that provides wastewater service to 100 residences and to rehab two stormwater outfalls that provide drainage to nearly 13 acres of land and 60 private properties in the Mosby Woods community. This level of construction is necessary for the proper maintenance and rehab of our utility infrastructure. 

    We are making every possible effort to showcase sustainable construction practices, including special attention to tree removal and plantings, and we have worked with adjacent property owners to redirect access in order to save additional trees. We are completing a lot of work in a very small area. This project is a great example of how to organize rehab across publicly maintained infrastructure to limit environmental disturbances from multiple ingress/egress and leverage best practices for ensuring a sustainable environment for many years to come.
