linear feet stabilized

The City of Fairfax, Virginia, turned to us to restore 11,800 linear feet (LF) and stabilize an additional 20,000 LF of Accotink Creek, a major tributary to the Chesapeake Bay. Our environmental professionals and design engineers worked within a highly constrained environment in this successful endeavor. The stream restoration design included changes to the horizontal and vertical geometry of the stream, addition of riffle-pool sequences to help with grade control and energy dissipation, installation of control structures such as cross vanes, and bioengineering techniques using native plants to enhance bank stabilization and riparian buffer diversity. Public outreach efforts with local citizen groups and associations were critical as many of the streams abutted city parks and residential properties.
