Members and Supporters

The Open Space Council is a coalition of organizations - nonprofits as well as city, county, regional, state and federal public agencies - involved in conserving, stewarding, and promoting the use of parks, trails, and open spaces in the San Francisco Bay Area. 

Members are organizations and agencies who acquire, manage and provide resources to land. Supporters are nonprofit organizations who provide services to, connect people to, advocate for and otherwise support the protection of land.
