About Us

Our Mission and Vision

The Santa Clara Valley Open Space Authority conserves the natural environment, supports agriculture and connects people to nature, by protecting open spaces, natural areas and working farms and ranches for future generations. 

We envision the Santa Clara Valley and its surrounding hillsides as a beautiful place where a vibrant network of interconnected open spaces, trails, wildlife habitats and thriving agricultural lands enrich the region’s cities and make it an exceptional and healthy place to live, work, learn and play. 

To date, the Open Space Authority has protected approximately 30,000 acres–providing nature-friendly outdoor recreation and preserving the natural beauty and environmental health of the Santa Clara Valley. 

How We Work

The Open Space Authority is a public, independent special district created by the California state legislature in 1993 at the urging of community leaders who saw the importance of saving the irreplaceable natural landscapes of the region.

The agency is funded primarily through a $24 per year parcel tax (referred to as Measure T) and a $12 per year parcel benefit assessment (referred to as District 1). We leverage our modest ongoing funding 3:1 through public and private grants.

How We're Governed

The Open Space Authority is governed by an elected Board of Directors with a Citizens' Advisory Committee that serves as a community liaison. 

The Open Space Authority is in the business of forever.
