Sustainable Sites Initiative (SITES)

The Sustainable Sites Initiative (SITES) is a program that provides standards to design, develop, and maintain outdoor spaces—like parks, gardens, and campuses—in an environmentally responsible way. It encourages practices that protect natural resources, improve biodiversity, reduce water and energy use, and promote climate resilience. By following SITES guidelines, designers and builders create outdoor environments that are beautiful, functional, and sustainable, supporting healthy ecosystems and communities while minimizing negative environmental impacts.
