Sonoma County Ag + Open Space

Sonoma County Ag + Open Space permanently protects the diverse agricultural, natural resource and scenic open space lands of Sonoma County for future generations. The organization is responsible for the perpetual protection of over 124,000 acres of land throughout our region. These agricultural and open space lands are protected through a quarter-cent sales tax initially approved by voters in 1990 and reauthorized in 2006.
