Scotts Run at Old Meadow Stream Restoration Project SD-000031-184

Project Update: May 25, 2021

Construction began January 2021 and is expected to be completed winter of 2022.

Project Background

The Scotts Run at Old Meadow stream restoration project will restore 2,800 linear feet of Scotts Run and tributaries using Natural Channel Design in Tysons. The project is within Scotts Run Stream Valley Park owned by the Fairfax County Park Authority. Approximately 246 acres of highly urbanized development drain to the project site; 53 percent of which are impervious. The existing stream channel exhibits eroded and over-widened banks, head-cuts and the potential for further bed and bank instability. Restoration objectives include stream stabilization, water quality improvement, aquatic and riparian habitat enhancement and reconnection of the channel with its floodplain.

The project is being constructed in collaboration with Cityline Partners, LLC (Cityline). On April 9, 2013, Fairfax County approved Cityline’s rezoning application for the Scotts Run South Development (RZ 2011-PR-010) which requires Cityline to prepare a design and construct a stream restoration project in a portion of Scotts Run within the Scotts Run Stream Valley Park. Per the approved proffer, Cityline will prepare a preliminary plan for approximately 2,600 feet of stream restoration that identified two project phases. Cityline funded the design and construction of Phase 1 that includes approximately 700 feet of stream restoration just above Dolley Madison Boulevard. As part of the Stormwater Capital Improvement Program, Fairfax County finalized designs and is funding construction of Phase 2 that includes approximately 2,100 feet of Scotts Run that is upstream and contiguous with Cityline’s plan. The County and Cityline will implement construction of Phases 1 and 2 concurrently, for a total length of 2,800 linear feet of restored stream.

Combining the two stream restoration projects will allow the Cityline Phase 1 plan to be implemented well before it would otherwise be completed if Cityline were to perform this work independently per the schedule outline in the proffer. Consolidation of the projects will also lower construction costs and promote the protection and restoration of stream valleys, which is a priority of the adopted Comprehensive Plan and part of the Tysons Urban Design Guidelines. Additionally, stormwater improvement and stream restoration projects for Tysons are included in the adopted Scotts Run Watershed Management Plan and are part of the Fiscal Year 2020 Capital Improvement Program.

Project Description

The project includes restoration of approximately 2,800 linear feet of Scotts Run, its tributaries, stormwater outfalls and the floodplain within the stream valley between Old Meadow Road and Dolley Madison Boulevard.

Project Location

The project is located between Old Meadow Road and Dolley Madison Boulevard in Mclean.

ScottsRunStreamRestoration-Phase I&II


Construction is scheduled to be completed during the Winter of 2022. Final landscaping will depend on the weather and planting season.

What to expect

The project will require the use of heavy construction equipment. Dump trucks will deliver materials to the construction entrances off Old Meadow Road and Chain Bridge Road. Timber mats will line the access road through the stream valley to transport equipment and materials while minimizing soil compaction and protecting existing trees. Tree removal will occur for access and stream construction with an extensive native landscaping effort to follow.

Project cost and funding source

Construction of the Scotts Run at Old Meadow stream restoration project has been awarded bid for a total of $2,215,000. Cityline will fund their stream restoration construction costs of $706,000. The Highland District development adjacent to Scotts Run also has proffered stream restoration commitments. The developer will pay funds towards stream restoration efforts at both the site plan approval phase and prior to building occupancy.

Stormwater projects are funded through the county Stormwater Service District.
