Rock Creek–Bingham Run Regenerative Stormwater Conveyance Design-Build

Rock Creek Park, a favorite spot among Washington, DC bikers, hikers, birders, runners and skaters, is a natural oasis amidst a highly urbanized landscape. Administered by the U.S. National Park Service, this popular park contains many degraded streams. Biohabitats is currently helping the District Department of the Environment (DDOE) restore one of them, Bingham Run, an ephemeral tributary to Rock Creek.

A regenerative stormwater conveyance (RSC) approach is being applied to this design-build restoration of 800 linear feet of incised stream channel. This involves raising the channel bed and reconnecting the stream with its floodplain and riparian wetlands to optimize the conversion of stormwater to groundwater and reduce its erosive energies. The aim of this project is to demonstrate this technology as an alternative to traditional approaches to stream and outfall erosion, such as piping, rip rap and hard structures. The RSC approach will improve water quality by stopping head-ward migration of the channel incision. It will also improve local hydrology by tempering the influence of stormwater runoff on the stream, converting “peaky” surface discharge into shallow seepage, reducing existing forested stream bank erosion and tree loss, and improving the quality and quantity of water delivered to downstream reaches.
