Snakeden Branch at Lake Audubon Stream Restoration Project

 

Project Update

Construction began on October 10, 2019.

Project Background

snakeden-branch-1
Exposed utilities (including sanitary sewer) are a potential human and environmental health hazard.

Staff of the Stormwater Planning Division worked closely with neighbors and staff from the Reston Association to create a plan to restore this highly degraded stream with many exposed sewer pipes between South Lakes Drive, Wakerobin Lane, Cedar Cove Court and Lake Audubon.

Surveys were done to ensure that the endangered Small Whorled Pogonia (not found) and the Northern Long-Eared Bat (not found) would not be impacted by the project.

Surveys determined the condition of the stream channel, soils, tree cover and documented the plant species and the condition of the plant communities on site.

The design has avoided impacts to private property and tree canopy to the greatest extent possible.

Project Description

The project will restore 750 linear feet of the stream channel to prevent erosion, convey stormwater, protect infrastructure, improve soils and support native vegetation.

The primary goals of the restoration are:

  • Improve water quality by removing Nitrogen, Phosphorous and Total Suspended Solids
  • Protect the infrastructure associated with the sanitary sewer system
  • Remove invasive vegetation in the restoration site
  • Reforest the area with native vegetation after construction
  • Improve wildlife habitat

Project Location

The restoration is between South Lakes Drive, Wakerobin Lane, Cedar Cove Court and Lake Audubon.
