The project will restore approximately 2,400 linear feet of stream channel. The existing channel is unstable as evidenced by tall, vertical, raw stream banks and the deep and widening stream channel. This instability erodes property, undermines trees causing them to fall, and threatens sanitary and storm sewer infrastructure throughout the corridor. 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.
The project is located on public land bounded on the upstream by Carrleigh Parkway and on the downstream by Greeley Boulevard. The project is in the Springfield magisterial district and in the Accotink Creek Watershed.
The most recent design plan was received on September 3, 2020 and is under review. After project-related land acquisitions are complete, the project will move to the next design phase. Due to the COVID-19 pandemic, there is not an in-person public meeting scheduled at this time.
The environmental benefits of the project are:
Decreased streambank erosion
Protection of public infrastructure including threatened sanitary and storm water pipes
Improved instream and riparian habitat for wildlife
Restored ecological function of the stream corridor
Improved water quality by reducing Nitrogen, Phosphorous and Total Suspended Solids
Design is anticipated to be complete in winter 2021/2022. Construction timing is dependent upon funding allocation, land acquisition and all necessary permit approvals. There will be a Pardon Our Dust meeting prior to the start of construction activity.
What to Expect
Flagging, survey markers, and tree tags are visible throughout the project area. At times, contractors and staff may be onsite to validate field conditions and proposed improvements. Staff will be wearing high-visibility clothing. Once construction begins, access and deliveries will enter the site from proposed access points at Carrleigh Parkway and Greeley Boulevard. The typical work week is Monday through Friday starting after 7:00 a.m. Note that at some periods during construction, work may occur on weekends. Construction activities on weekends would occur after 9:00 a.m. These start times are in accordance with the Fairfax County Noise Ordinance.
Project Cost and Funding Source
Design of the Accotink Creek Tributary at Carrleigh Parkway stream restoration project is funded for $530,000. Construction funding is dependent upon future budget availability and allocations. Stormwater projects are funded through the county Stormwater Service District.
Presentations to the Community
Typically, the Stormwater Planning design team shares the project design with the community at a public meeting. However, due to the COVID-19 pandemic, the project’s concept design and presentation will be shared below. Questions are encouraged and requests for additional information should be forwarded to the Project Manager.
