  • Promote restoration of open space to provide visual, recreational, and habitat amenities.
  • Preserve vestiges of the natural desert landscape and provide opportunities for hiking, horseback riding, bicycling, and more passive recreation in a natural setting.
  • Contribute to the preservation of wildlife habitat, especially interconnected areas which foster the free movement of wildlife, within the city.
  • Promote a continued economic benefit to the region by protecting open space areas for the visual and recreational enjoyment of residents and visitors alike.
  • Provide a mechanism for recognizing and protecting public and private lands that have been designated for preservation by the property owner. Applicability.
