The SP-PO Parks and Open Space (Special Purpose) district is intended to help preserve and protect lands set aside for park and open space use. Such areas and facilities provide many benefits to City residents and visitors. They provide cultural and recreation opportunities; preserve natural and scenic areas; protect sensitive natural resource areas; and offer refuge from the built, urban environment. The SP-PO district is intended to be applied to public parks and open space lands under the jurisdiction of City, state or federal government agencies. The district may be applied to privately owned lands only with the private property owner's consent.
