Underground Stormwater Detention System At Quantico National Cemetery
Oldcastle Precast provided Storm Capture as a solution for the underground stormwater detention system at the new administration building site at Quantico National Cemetery in Triangle, VA. The new administration building expansion, just inside the cemetery’s entrance gates on Joplin Road in Triangle, includes about 4,500 square feet of office and administrative space and a covered portico of about 2,500 square feet.
For civil designer AMEC Environment & Infrastructure, Kennesaw, Georgia, key concerns were to control runoff from newly constructed impervious surfaces preventing storm drain overloading, and other downstream issues such as flooding and erosion, and to achieve this with minimal footprint on the compact project site. AMEC specified Oldcastle Precast’s Storm Capture stormwater detention system to manage the post-construction stormwater runoff.
The precast concrete stormwater detention structure, supplied by Oldcastle Precast, included (16) sixteen, 7 ft. x15 ft. x7ft tall precast, detention modules, and an integrated outlet control structure. The underground, high-strength structural concrete storage modules, which were installed in the early fall of 2013, provided 12,336 cubic feet of underground detention, and the outlet control structure provided controlled discharge and overflow capabilities. The Storm Capture modules incorporated several inlet pipes, as well as four manway access points to allow maintenance access into the stormwater management system. An impermeable, polyethylene membrane was used to wrap the Storm Capture module assembly to provide a 100% watertight system.
WC Spratt, Fredericksburg, VA installed the Storm Capture system for general contractor Leebcor Services LLC, Williamsburg, VA, and the architect for the project was Matrix Settles of Arlington, Va.
Comprised of 725 acres, Quantico National Cemetery is a military cemetery for veterans of the United States Armed Forces and was established in 1983 adjacent to the Marine Corps Base Quantico.
The Storm Capture Total Stormwater Management System offers many solutions for stormwater management needs: detention, retention, treatment, and harvesting using a combination of many parts designed to solve specific requirements.
