Apply Today for SITES Certification

The Sustainable Sites Initiative (SITES®) is the most comprehensive program and toolkit for developing sustainable landscapes. The SITES program is 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.

SITES draws on the experiences gained from a two-year pilot program involving more than 100 projects. Forty-six of these pilot projects have achieved certification, including landscape projects at corporate headquarters, national and city parks, academic campuses and private homes. Information and knowledge gained from participating pilot projects informed the development of SITES v2: Rating System for Sustainable Land Design and Development, a guide which provides best practices, performance benchmarks, and tolls for creating ecological resilient landscapes and rewards successful projects through certification.

SITES offers a systematic, comprehensive rating system designed to define sustainable sites, measure their performance, and ultimately evaluate the value of landscapes. Administered by the Green Business Certification Inc. (GBCI), the SITES rating system can apply to development projects located on sites with or without buildings, including open spaces, streetscapes and plazas, commercial, residential, education/institutional, infrastructure, government, military, and industrial.

The SITES rating system uses progressive industry standards for landscape design and incorporates additional recommendations from technical experts in the fields of social science, botany and horticulture, hydrology, materials, and human health and well-being.

SITES was developed through a collaborative, interdisciplinary effort of the American Society of Landscape Architects, The Lady Bird Johnson Wildflower Center at the University of Texas at Austin, and the United States Botanic Garden.
