SSI is a comprehensive rating system to score the sustainability of the managed landscape.
The Sustainable Sites Initiative (SITES®) is a program based on the understanding that land is a crucial component of the built environment and can be planned, designed, developed, and maintained to protect and enhance the benefits we derive from healthy functioning landscapes. Sustainable landscapes create ecologically resilient communities better able to withstand and recover from episodic floods, droughts, wildfires, and other catastrophic events. They benefit the environment, property owners, and local and regional communities and economies.
The SITES program provides tools for those who influence land development and management practices and can address increasingly urgent global concerns such as climate change, loss of biodiversity, and resource depletion. They can be used by those who design, construct, operate, and maintain landscapes, including but not limited to planners, landscape architects, engineers, developers, builders, maintenance crews, horticulturists, governments, land stewards, and organizations offering building standards.
The material on which SITES is based was developed through a collaborative, interdisciplinary effort of the American Society of Landscape Architects Fund, the Lady Bird Johnson Wildflowr Center at The University of Texas at Austin. and the United States Botanic Garden.
