Northern Virginia Stream Restoration Bank
The Northern Virginia Stream Restoration Bank (NVSRB) is a partnership between Wetland Studies and Solutions, Inc. (WSSI) and Reston Association (RA). Since 2008, NVSRB has restored almost 9 miles of degraded stream channels.
NVSRB has completed stream restoration in The Glade and Snakeden watersheds, as well as Forest Edge North and South in the Colvin Run watershed. More Colvin Run watershed work is happening now: Wiehle Avenue North and Hickory Cluster.
NVSRB started on the ground work in February 2008, after more than five years of data collection and planning. Since then Reston has gained more than 45,000 linear feet of stream channel improvements.
In the development of Reston, forested lands were converted to buildings, roads, and other impervious surfaces that bar the infiltration of stormwater into soils. That causes higher runoff volumes during rain events which, combined with higher peak flows from outdated management techniques, result in higher flow energy in Reston's streams. The streams have suffered severe erosion and significant downstream sediment deposition. That erosion threatens adjacent trees, trails, and sanitary sewers, and the sediment impacts Reston's lakes and other community waters. WSSI is restoring streams using Natural Channel Design techniques that help the streambeds and banks withstand the high urban flow rates.
We invite you to browse the NVSRB information here as well as the rest of the WSSI website. Our frequently asked questions section provides an overview of stream restoration and how it benefits Reston, as well as the finer details of the process. You can also ask us a question if you want more information.
