Wakerobin-Cedar Cove Stream Restoration

Wakerobin-Cedar Cove Stream Restoration

Overview

One of Reston’s  most eroded stream channels lies between Wakerobin Lane and Cedar Cove Cluster, just south of South Lakes Drive and downstream of South Lakes High School, Langston Hughes Middle School, and Whisperwood Cluster. The channel, which feeds into Lake Audubon, has been eroding continuously since the initial development on the watershed in the late 1970s and early 1980s. With approximately 50 percent of the 50-acre watershed now covered with impervious surfaces such as roadways, parking lots, rooftops and sidewalks, the stream is in need of stabilization and restoration to prevent further damage to the channel itself, public and private utilities, members’ properties and Lake Audubon.

Over the course of four dredging projects conducted on Lake Audubon, Reston Association has spent approximately $100,000 to remove around 2,000 cubic yards of sediment from the lake cove just below this channel.

Timeline

Jul. 2015: An exposed sanitary sewer pipe crossing the eroded channel was discovered to be draining into Lake Audubon. Fairfax County responded and repaired the pipe within five days, and after water-quality tests showed the lake to be safe, RA lifted recreational restrictions. Read more.

Oct. 20, 2015: The Fairfax County Board of Supervisors approved a Planned Residential Community (PRC) plan to expand South Lakes High School with a 40,000-square-foot addition and additional parking.

Oct. 22, 2015: Department of Public Works & Environmental Services staff, accompanied by representatives from RA, performed a stream assessment and confirmed the stream was highly degraded and public and private utilities were exposed. (Click the "DPWES Stream Assessment" link on the right.)

Dec. 17, 2015: The RA board passed four motions intended to facilitate a more collaborative process and ensure the proposed expansion of SLHS does not adversely impact stormwater management and soil erosion in the south Reston area. (Links to related letters on the right.)

Jan. 28, 2016: The RA Board of Directors hosted a community dialogue. At this meeting, the board directed staff to conduct an independent review of the stormwater management plan proposed for the SLHS expansion and explore additional options for mitigation. Read more.

Feb. 3, 2016: RA sent a letter to Sharon Bulova, Chairman of the Fairfax County Board of Supervisors, requesting that the Wakerobin/Cedar Cove stream restoration and sanitary sewer line stabilization/maintenance project be expedited for funding, design and construction in the county’s capital improvement program.
