The Huntington Levee project in Fairfax County, Virginia is the recent recipient of the Envision Bronze award for sustainable infrastructure.
The Huntington Levee project consists of two main elements: a levee that runs parallel to Cameron Run that consists of an earthen embankment and a series of steel-reinforced concrete panels formed in the shape of an I, known as an I-wall, as well as a two-stage pumping station located at the east end of the levee. The levee itself is 2,800 feet long, beginning west of Fenwick Drive and running eastward. The earthen embankment portion of the levee is between 6 and 11 feet high, with a 4-foot high I-wall situated on the top. The top of the levee is 13 feet wide and includes an 8-foot wide asphalt recreational trail. The project also includes a collection drain system to control ground water seepage, new storm drains to connect the existing storm drains to the pumping station, and concrete channels and a vegetated swale to divert stormwater collected behind the levee to the pumping station. The whole system has been designed to protect the community from extreme 100-year flooding events—floods that have a one per cent chance of occurring in any given year.
Fairfax County’s Department of Public Works and Environmental Services delivered this award-winning sustainable project in close collaboration with lead engineer Arcadis U.S., Inc., whose team included Michael Baker International and William H. Gordon, Inc. Regulatory partners included FEMA and the Virginia Department of Environmental Quality. Archer Western was the construction contractor.
“This project is vital to ensuring the safety of the Huntington community from risks associated with flooding. Hundreds of people in the area can rest assured they are better protected as a result of this project,” said Melissa Peneycad, ISI’s Acting Managing Director. “ISI is pleased to award this project with Envision Bronze for sustainable infrastructure.”
