Project Background

The project is in the Dogue Creek Watershed and on Greendale Golf Course in the Franconia District. Our efforts help the county meet water quality standards for its residents. When completed, the project will reduce soil bank erosion and sediment pollutants and reduce nitrogen and phosphorus levels in the Dogue Creek Watershed. The county will modernize its stormwater infrastructure to meet the needs of today’s climate. Most especially, the natural habitat on the course, and elsewhere in the watershed, will be revitalized by clearing invasive brush and dropping unwanted trees in the canopy on the course and reforesting 4 acres offsite at Huntley Meadows. The Huntley Meadows Reforestation Project will serve as a mitigation bank, generating credits for the golf course that enhances our green corridors in the Huntington community.

Project Description

The stream restoration project will restore 1,905 linear feet of stream channel and dredge a pond that serves a 200 plus acres drainage area. The existing channel is unstable as evidenced by tall, vertical, raw stream banks and the deep and widening stream channel. This instability erodes away property, undermines trees causing them to fall, and threatens storm sewer infrastructure throughout the corridor. Eroded sediment transported to the wet pond adversely impacts its effectiveness, risking flood events on the Greendale Golf Course. This project is part of larger efforts to restore many of Fairfax County’s degraded streams while improving overall water quality and the condition of the Chesapeake Bay.

Project Location

The project is located primarily on Greendale Golf Course, beginning upstream at culverts south of Treetop Lane and ending at a wet pond on the golf course east of McKenna Way. The project is in the Franconia Magisterial District. Construction entrances to the project will be at Horgan Court and Treetop Lane.

Project Phase

The final design was approved in June 2025. Since then, Stormwater Planning and Utility Design and Construction have been collaborating to secure construction and administration contractors. We anticipate Construction Notice-To-Proceed to be issues in the Fall 2025.

Project Timeline

• Construction begins Fall 2025
• Expected completion is Spring 2027

What to Expect

Flagging, survey markers, and tree tags are visible throughout the project area. Contractors will be onsite preparing the site for construction and staff will be onsite to validate field conditions and progress.

Staff and contractors will be wearing high-visibility clothing. Access and deliveries will enter the site from proposed access points at Horgan Court and Treetop Lane. The typical work week is Monday through Friday starting after 7 a.m. Note that at some periods during construction, work may occur on weekends. Construction activities on weekends would occur after 9 a.m. These start times are in accordance with the Fairfax County Noise Ordinance.

Project Cost and Funding Source

Construction of the Dogue Creek at Greendale Golf Course Stream Restoration and Pond Dredge is funded for $4,811,035. Construction funding is dependent upon future budget availability and allocations. Stormwater projects are funded through the county Stormwater Service District and the Stormwater Local Assistance Fund (SLAF) grant program.
