Stream restoration efforts are underway at Colvin Run Stream Valley at Wiehle South.
The Reston Association released a video on Tuesday (Feb. 5) detailing the project’s progress, which is expected to be finished by the summer.
Construction crews are working on small sections of the stream at a time as they use track equipment and various sizes of rocks to raise the bottom of the stream, according to the video. The rock is meant to reconnect the stream with the flood plain.
The Reston Association is working with the Wetland Studies and Solutions Inc., a consulting group that has designed and restored streams for Reston before. The Northern Virginia Stream Restoration Bank is funding the project.
Once the project is finished, the area will be stabilized with erosion netting and native plant seeds will be planted sometime in the fall, according to the video.
Until then, caution signs mark the walkable paths around the work site, which will only be closed during construction hours.
Representatives from the Northern Virginia Stream Restoration Bank (NVSRB), which include wetland experts and staff from the Reston Association (RA), have issued updates over the past week, informing residents of the status of various local stream restoration projects, and warning of new projects set to begin in November.
Currently, restoration of the streams at Brown’s Chapel Park and Vantage Hill is underway, and RA staff said the areas will be under construction through the end of the year. Staff posted on the RA website last week reminding local residents that the areas are closed during working hours, and asked everyone not to cross the gates or safety fences.
Construction at Brown’s Chapel Park is expected to be completed in December, and at Vantage Hill in January.
In November, restoration of Lake Anne East, near Inlet Cluster, and Lake Anne West, near Waterview Cluster, is set to begin.
RA staff said they expect construction of all stream channels to be completed by fall of 2018.
RA staff said that they expect all wood acquired for the project will be used in the construction of thestreams themselves, but that any wood that is left over will be split into firewood and will be made available to Reston residents at Brown’s Chapel Park in the lot near the upper ball fields.
Once all restoration construction is complete, RA staff said hundreds of new trees will be planted along Reston’s streams. Read More
