To date, the Open Space Authority has preserved approximately 30,000 acres of open space–protecting the health and well-being of the Santa Clara Valley and its residents. Additionally, this protected land connects over 1 million acres of habitat between the Santa Cruz Mountains and Diablo Range. The Open Space Authority also provides equitable access to nature through Urban Grants, with nearly $15 million invested to connect urban residents to the outdoors in their own neighborhoods.
