A $1 million project to restore 750 feet of Snakeden Branch at Lake Audubon is nearly complete.
In a recent Reston Association video, staff indicated that construction on the project — which is critical to prevent erosion and effectively channel stormwater — is expected to be completed sometime this week.
The restoration project, which was requested by RA members, will protect the area’s sanitary sewer system, improve water quality, and boost the wildlife habitat, according to Meghan Fellows, a project manager with the county’s stormwater planning division.
Major erosion caused the branch to become “white water rapids” in the event of rain, Fellows said.
The county, which already reforested part of the area in the spring, will provide more plantings in the fall. The restoration area is focused on the area between South Lakes Drive, Wakerbin Lane, Cedar Cove Court and Lake Audubon. Construction began in October 2019.
RA and county staff will continue to monitor the effectiveness of the stream restoration project in the coming months, according to William Peterson, RA’s watershed manager.
Fellows noted that the project is primarily intended to ensure the stream can handle stormwater and provide stability to the surrounding wildlife, given then nearly 48 percent of it is composed of impervious surface.
Prior to the project’s completion, eight sanitary lines were exposed.
