The open space zone is specifically intended to include two (2) types of land use. The first is to encourage the preservation of a natural environment in an otherwise urban setting; to hold for future generations open space in which plants and animals can be protected and studied; to inhibit erection of unnecessary buildings on a floodplain, on areas of severe slope and areas of fault line and rockslides; to provide suitable areas for recreation and relaxation, and to alleviate stream pollution. The second is to designate and preserve as a land use public land that is predominately free of structures and has been landscaped, developed and set aside for the use and benefit of the public.

   D.   The accessway does not create a perceived zone boundary line by its physical appearance.

   E.   Area around the accessway is revegetated if past usage or new construction improvements have removed natural habitat.

   F.   Use of accessways is designed to prevent any environmental damage to the O-1 zone habitat.

   G.   When the accessway crosses public property:

      1.   It does not create physical restrictions of recreational usage of the O-1 zone; and

      2.   The applicant has established a legal right to cross such public property.
