The American Society of Landscape Architects (ASLA) is the national professional association representing landscape architects, with more than 17,000 members in 48 chapters, representing all 50 states, U.S. territories, and 42 countries around the world, plus 68 student chapters. The group was founded on January 4, 1899, to "establish landscape architecture as a recognized profession in North America," "develop educational studies in landscape architecture," and "provide a voice of authority in the 'New Profession'"
ASLA’s 3,000 square feet (280 m2) green roof will be honoured by GRHC in the ‘Institutional Intensive’ category, which honours innovative green roof design in the US, Canada and Mexico.
