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.
