In response to the 2005 Base Realignment and Closure (BRAC), the Army National Guard and the National Guard Bureau Joint Command relocated more than 1000 personnel from leased property to an existing facility in northern Virginia. This required the construction of a 193,000 square foot addition. The size of the building and its required security measures would have allowed little room on the site for outdoor space and would have run afoul of stormwater runoff requirements in the sensitive Chesapeake Bay watershed

LPDA worked as part of a multidisciplinary team to solve these problems with a 37,000 square foot intensive green roof atop the building’s ground floor. The green roof provides critical outdoor space for general personnel and ceremonial use. The project also included extensive site modifications, utility redesign, and underground stormwater systems. Because of the limited site, AT/FP force protection measures and hardening of portions of the facility were required.
