Washington, D.C., November 5, 2009 — Today, the
Sustainable Sites Initiative released the nation’s
first rating system for the design, construction and 
maintenance of sustainable landscapes, with or without 
buildings. A partnership of the American Society of 
Landscape Architects (ASLA), the Lady Bird Johnson 
Wildflower Center and the U.S. Botanic Garden, the 
Initiative’s rating system represents four years of 
work by dozens of the country’s leading sustainability 
experts, scientists and design professionals, as well 
as public input from hundreds of individuals and dozens 
of organizations to create this essential missing link in 
green design. The announcement took place at the U.S. 
Botanic Garden in Washington. To learn more, click here.
