SITES rating system

SITES provides a comprehensive framework for designing, developing and managing sustainable and resilient landscapes and other outdoor spaces. SITES is the ideal tool to support nature positive design. This track record has earned SITES certification an important place in the rapidly evolving ESG reporting world as a standard of leading commitment.

SITES can be applied worldwide to a variety of projects types (with or without buildings), including:

Open spaces

Local, state and national parks; botanic gardens; arboretums

Streetscapes and plazas

Municipal zones; transportation hubs


Retail and office areas; corporate campuses


Neighborhoods or community areas

Educational or institutional

Public and private university campuses; museums; hospitals

How SITES works

SITES-certified projects help reduce water demand, filter and reduce stormwater runoff, enhance biodiversity, provide pollinator and wildlife habitat, reduce energy consumption, improve air quality, improve human health, increase outdoor recreation opportunities and much more.

By providing performance measures rather than prescribing practices, SITES supports the unique conditions of each site, encouraging project teams to be flexible and creative as they develop beautiful, functional and regenerative landscapes. The SITES v2 Rating System is a 200-point system with four certification levels of achievement.


70-84 points


85-99 points


100-134 points


135+ points

Synergies between SITES and LEED

The SITES and LEED rating systems are complementary and can be used independently or in tandem. LEED applies to your project building and the site it is located on, and SITES applies to everything on your site, except your building (with a few exceptions). If you would like your project to benefit from certifying to both SITES and LEED, you can take advantage of the synergies between them.

Eligibility and fees

SITES applies to a diverse set of project types, contexts and stages of development.

  • Projects in the Planning Phase: SITES Precertification. is an optional review pathway focused on a project’s plan, including its intended design and construction strategies.
  • New Construction and Major Renovation of Existing Sites: Using SITES for new construction projects lays a very important and critical foundation for a healthy, sustainable and resilient project. The decisions made at every stage impact overall performance in future conditions. Ideally, a project should start with SITES when it is selecting a location for its development or during pre-design stages and continue to apply the rating system throughout design and construction. A project can only achieve certification once construction has been completed.
  • Existing, Built Landscapes: Projects can be evaluated by their sustainable site management and are encouraged to report their social, environmental, and economic benefits. This certification is currently in a pilot phase. Contact if you are interested in participating or learning more.

There is no maximum size for a SITES project, but the minimum is set at 2,000 square feet (or 185.8 square meters). For projects over 100 acres, please contact Additional fees will apply.
