In an effort to provide a more unified, secure campus that brings together its executive leadership and operational management, the Department of Homeland Security (DHS) is consolidating its headquarters in the National Capital Region at the 176-acre St. Elizabeths Campus. Phase 1, the multi-award winning United States Coast Guard Headquarters, delivered in 2013 and its portion alone involved the largest excavation project in D.C. history, creating 1.6 million cubic yards of dirt. The design team developed an 11-level facility in which only the top two levels are above grade; the remaining nine levels are built into and extend out of the landscape, cascading down the hill. Despite its massive scale, the use of glass to provide natural light and eight planted interconnected courtyards unite this very site-specific building. Each greenroof and courtyard is both a literal and abstract expression of five local eco-regions, from the Piedmont uplands down to the coastal plain encompassing 200,000 plants, more than 300 native trees, and about 100 varieties of Sedum. Due to the variety of plants ranging from shrubs to grasses to Sedum mats from Sempergreen, there are four different soil blends on the project from rooflite®.
