Project Background

This project was developed as a result of Long Branch Central being declared an impaired water by the Virginia Department of Environmental Quality (DEQ). DEQ issued a Total Maximum Daily Load (TMDL) requirement to reduce sediment for Accotink Creek Watershed in August 2017. Under the Accotink Creek TMDL, Fairfax County is assigned a waste load reduction requirement for the 3.7 square mile Long Branch Central watershed of 2,433 tons per year. Meeting these reduction targets is a requirement of the county's Municipal Separate Storm Sewer System (MS4) Permit. In addition, the Long Branch Central WMA project will reduce the sediment load going to Lake Accotink, thus protecting the county's investment in that facility. The Long Branch Central WMA project will improve water quality, meet the Long Branch Central sediment TMDL load reduction targets and improve habitat within the stream corridor.

Project Description

The Long Branch Central Watershed Management Area project is a collaborative effort of the Department of Public Works and Environmental Services, the Fairfax County Park Authority and the Northern Virginia Soil and Water Conservation District.

The primary goals of the project are:

• Meet the Long Branch Central TMDL waste load reduction requirements
• Improve water quality within the Long Branch Central watershed
• Improve habitat and environmental health (ecological lift)

To meet these goals, the county will restore about six and a half miles of stream and 75 stormwater outfalls.

Project Location

The project is in the Braddock Magisterial District between Little River Turnpike and Burke Station, Braddock and Wakefield Chapel Roads.

Project Phase

The project is in the design phase for the first three projects (Kristin Lane at Rutherford Park, Ilda Pool at Braeburn Drive, and Willow Woods Park South of Braeburn Drive).

What to Expect

There will be field studies, plan development and public meetings through the process. Construction will occur in phases and each phase will be outlined in the project implementation plan. The final construction schedule is dependent upon funding availability and project permitting. When construction occurs, there will be truck traffic to the project sites. Residents should expect periodic deliveries of material using dump trucks to the site throughout the week starting after 7 a.m. on weekdays. Note that at some periods during construction, work may occur on weekends. Deliveries on those days will be made after 9 a.m.

Project Cost and Funding Source

Construction costs for the Long Branch Central Watershed Management Area projects will be developed once projects are defined. Stormwater projects are funded through the county Stormwater Service District.
