The Open Space Authority began in 1993 with a grassroots effort by citizen activists wanting to protect Santa Clara Valley’s important natural resources. We started as a small agency with an important role to play and have since grown into a diverse organization with greater capacity to make progress on our mission of conserving the natural environment, supporting agriculture, and connecting people to nature. Measure Q has provided further opportunity to fulfill our mission by enabling us to expand public access to nature in and around our urban communities, increase our environmental education programming, and help us maintain our open space preserves for public enjoyment.
In this 25th Anniversary Year, we want to celebrate the natural and working lands around us, and just as importantly, celebrate our constituents, who have been so supportive of our work all along the way. We invite you to take every opportunity to get outside and enjoy nature. Join us all year long with fun events and catch up on our past accomplishments in our monthly newsletter.
The accomplishments we've achieved together over the past 25 years are too numerous to mention, but just to list a few of our favorites...
Over 25,000 acres of land protected and 3 open space preserves available to the public year-round for hiking, mountain biking, and horseback riding
Permanent protection of habitat for 25 rare and endangered species of wildlife and plants
Providing over $10,000,000 to more than 30 Urban Open Space Projects throughout our jurisdiction, including awarding the first Measure Q grant to Bill’s Backyard: Bridge to Nature at the Children's Discovery Museum in San Jose
208 different types of free environmental education programs to more than 20,000 of members of the public in our preserves and urban parklands
700 currently active volunteers that participate in trail work, leading programs, and community outreach
