Accotink Creek Tributary at Carrleigh Parkway

(AC82-0015) Project Number: SD-000031-228

Project Update: January 11, 2024

Design is expected to be complete by Spring 2024.


Project Description

Picture - Accotink Creek Carrleigh Pky
Existing conditions

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 away 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.

Project Location

The project is located primarily on public land bounded on the upstream by Carrleigh Parkway and on the downstream by Greeley Boulevard. The project is in the Braddock magisterial district.

Project Phase

The latest design plan was received in July 2023. Since then, Stormwater Planning has been actively collaborating with private properties to secure project-related easements. We anticipate completing the design by Spring 2024, and construction is set to commence in Summer 2024. We plan to conduct a "Pardon Our Dust" meeting before the construction kicks off.

Project Benefits

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

Timeline

Design is anticipated to be complete in Spring 2024. 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

Picture - Accotink Creek CarrleighFlagging, 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 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

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

We will host a "Pardon Our Dust" meeting before the commencement of construction activity.
