Is Open Space Really Open?

Of the 64,375 acres of publicly owned and leased land:

  • 60.4% (38,860 acres) is open to the public
    • Some of that land has on-trail-only restrictions for agricultural operations (5,169 acres) and closures for sensitive wildlife or vegetation habitat
  • 30.6% (19,693 acres) is agricultural land that is closed to the public
    • These lands are leased to local farmers and ranchers and are used to promote sustainable agriculture. When you add the 19,498 acres and the 5,169 acres that have on-trail-only restrictions, there are approximately 25,000 acres of open space dedicated to agriculture. Learn more about Agriculture on Open Space.
  • 9% (5,822 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.
