A.   Intent: These zones are intended to overlay any other zoning districts and regulations comprising or pertaining to areas to which it is applicable, so as to prevent undue negative interaction between aviation activities associated with the airport and the surrounding community. It is intended to protect the lives and property of users of the airport and of occupants of land in its vicinity by restricting "places of public assembly" within these zones. These zones are intended to preserve the utility of the airport and the public investment therein.
   B.   Zones: Development zones are hereby established within the airport land use zones. Such areas and zones are shown in subsection 13-13-10C of this chapter, consisting of one sheet prepared by the airport board and dated January 2004, a copy of which is made a part hereof by reference. The various zones are defined and described as follows:
      1.   Airport Runway Protection Zones: Airport runway protection zones are hereby established as trapezoidal areas centered about the extended runway centerline. Where both an existing and future threshold are planned for a runway, the runway protection zone will consist of the area enclosed by trapezoids for each planned threshold plus the lines connecting corresponding outboard corners of the two (2) trapezoids. Runway protection zones are sized based on aircraft expected to be served and approach visibility minimums for the ultimate conditions.
         a.   Visual And Not Lower Than One Mile Approach Visibility Minimums (Approach Aircraft A And B Only): A runway protection zone is established at each end of the runways. Each runway shall have protection zones that have a width of five hundred feet (500') at a distance of two hundred feet (200') beyond the runway threshold, widening thereafter uniformly to a width of seven hundred feet (700') at a distance of one thousand two hundred feet (1,200') beyond the runway threshold, with its centerline being the continuation of the centerline of the runway, for all other than utility runways. (Runway 11-29 is planned to have a NPI approach with not lower than 1 mile approach visibility minimums. Runway 5-23 is planned to have a NPI approach with not lower than 1 mile approach visibility minimums.)
      2.   Municipal Airport Zone/Airport Property: The municipal airport zone is hereby established as the land area owned by Toole County and held as the Shelby airport, exclusive of the airport runway protection zones.
