Is Open Space Really Open?

Of the 63,665 acres of publicly owned and leased land:

  • 60% (38,325 acres) is open to the public
    • Some of that land has on-trail-only restrictions for agricultural operations (4,348 acres) and closures for sensitive wildlife or vegetation habitat
  • 31% (19,497 acres) is agricultural land and closed to the public
    • These lands are leased to local farmers and ranchers and are used to promote sustainable agriculture. When you add the 20,879 acres closed exclusively for agriculture operations and the 4,348 acres that have on-trail-only restrictions, there are over 25,000 acres of open space dedicated to agriculture. Learn more about Agriculture on Open Space.
  • 9% (5,843 acres) is closed for other reasons
    • These areas are closed for public safety, wildlife/vegetation concerns, contract requirements, or because it is still under evaluation for potential public use.
