Questions About Our Work

What is a greenbelt?

Greenbelt is a term used in land-use planning which refers to areas of largely undeveloped, wild, or farm and ranch land surrounding or neighboring urban areas. Cities around the world have intentionally protected their greenbelts to ensure a healthy environment and to give residents access to all of the benefits this land brings—including fresh food, recreation, carbon sequestration, etc. The Bay Area’s greenbelt is approximately 3.6 million acres of land outside of cities and towns in our nine counties. This map shows urban land (gray) and greenbelt land (green) in our region.

What does Greenbelt Alliance do?

We shape the rules that govern growth around the San Francisco Bay Area so that the right development happens in the right places.

How do you shape the rules that govern growth?

We shape the rules that govern growth by advocating for, providing expertise on, and building support behind public policy and planning which promote conservation and smart growth. Here is a snapshot of our work last year. Click to enlarge.


Does Greenbelt Alliance buy land?

No. We promote good land-use decisions by shaping the policies and plans of counties, cities, and towns. For information on donating land or selling conservation easements, contact your local land trust.

Do you offer support to groups outside of the Bay Area?

Greenbelt Alliance focuses on the San Francisco Bay Area. However, our experts speak on land-use issues at conferences around the country and many of our policy reports and organizing tools are used by groups nationwide. Check out our research page to find the latest resources for smart growth and conservation activists. Browse our staff directory for speakers on issues that are important to your organization.

Yes! We offer volunteer internship opportunities which we post here when available.
