The George Washington University (GW) wanted to convert Square 80, an underutilized space, into an urban, multi-functional, sustainable plaza. STUDIO39 Landscape Architecture, PC was chosen to design and transform the site into social gathering spaces. Square 80 now serves as an urban plaza with a central open space and an outdoor classroom for the university’s Landscape Design & Sustainable Landscapes programs. STUDIO39, a landscape architecture firm based in Alexandria, VA, was perfectly suited for this project because of the firm’s focus on sustainable and green roof design.

Completed in 2010, Square 80 presented a unique opportunity to combine multiple sustainable elements into one project. The design harvests 100% of on-site rainwater for irrigation, maintenance and other amenities. Other sustainable elements of the project include biofiltration planters, pervious paving, underground cisterns, rain barrel, native plants, rain gardens and a bioswale. Interpretive signage designed by STUDIO39, made of recycled content, will be installed this month to explain how these elements work together.

Square 80 fits GW’s Sustainable Vision: “The George Washington University envisions a future with resource systems that are healthy and thriving for all. In efforts to enhance our campus, our nation’s capital and the world at large, the GW community is building a greener campus, providing research and intellectual discourse on policies and pathways to sustainable systems, and equipping students with the skills and knowledge to contribute to a sustainable future.”
