§ 177.54  LAND USE SAFETY ZONING.
   (A)   Safety zone boundaries. In order to carry out the purpose of this subchapter, as set forth above and also, in order to restrict those uses which may be hazardous to the operational safety of aircraft operating to and from the Littlefork Municipal Airport, and furthermore to limit population and building density in the runway approach areas, thereby creating sufficient open space so as to protect life and property in case of an accident, there are hereby created and established the following land use safety zones.
      (1)   Safety Zone A: All land in that portion of the approach zones of a runway, as defined in § 177.53 (A) hereof, which extends outward from the end of the primary surface a distance equal to two-thirds of the planned length of the runway, which distance shall be:
         b.   2,400 Feet for the East-West runway.
      (2)   Safety Zone B: All land in that portion of the approach zones of a runway as defined in § 177.53 (A) hereof, which extends outward from Safety Zone A a distance equal to one-third of the planned length of the runway, which distance shall be:
         b.   1,200 Feet for the East-West runway.
      (3)   Safety Zone C: All that land which is enclosed within the perimeter of the horizontal zone, as defined in § 177.53 (A) hereof, and which is not included in Zone A or Zone B.
   (B)   Use restrictions.
      (1)   General.  Subject to all times to the height restrictions set forth in § 177.53(B), no use shall be made of any land in any of the safety zones defined in § 177.54(A) which creates or causes interference with the operations of radio or electronic facilities on the airport or with radio or electronic communications between airport and aircraft, makes it difficult for pilots to distinguish between airport lights and other lights, results in glare in the eyes of pilots using the airport, impairs visibility in the vicinity of the airport, or otherwise endangers the landing, taking off, or maneuvering of aircraft.
      (2)   Zone A.  Subject at all times to the height restrictions set forth in § 177.54(B) and to the general restrictions contained in § 177.54(B)(1), areas designated as Zone A shall contain no buildings, temporary structures, exposed transmission lines, or other similar above-ground land use structural hazards, and shall be restricted to those uses which will not create, attract or bring together an assembly of persons thereon.  Permitted uses may include, but are not limited to, such uses as agriculture (seasonal crops), horticulture, animal husbandry, raising of livestock, wildlife habitat, light outdoor recreation (nonspectator), cemeteries, and auto parking.
      (3)   Zone B.  Subject at all times to the height restriction set forth in § 177.54(B), and to the general restrictions contained in § 177.54(B)(1), areas designated as Zone B shall be restricted in use as follows:
         (a)   Each use shall be on a site whose area shall not be less than three acres.
         (b)   Each use shall not create, attract, or bring together a site population that would exceed 15 times that of the site acreage.
         (c)   Each site shall have no more than one building plot upon which any number of structures may be erected.
         (d)   A building plot shall be single, uniform and non-contrived area, whose shape is uncomplicated and whose area shall not exceed the following minimum ratios with respect to the total site area:
 
Site Area at least (Acres)
But Less Than (Acres)
Ratio of Site Area to Bldg. Plot Area
Building Plot Area (Sq. Ft.)
Max. Site Population (15 Persons/A)

         (e)   The following uses are specifically prohibited in Zone B: Churches, hospitals, schools, theaters, stadiums, hotels, and motels, trailer courts, camp grounds, and other places of frequent public or semi-public assembly.
      (4)   Zone C:  Zone C is subject only to height restrictions set forth in § 177.53 (B), and to the general restrictions contained in § 177.54 (B)(1).
   (C)   Boundary limitations.  The municipality may regulate the location, size and use of buildings and the density of population in that portion of an airport hazard area under the approach zones for a distance not to exceed two miles from the airport boundary and in other portions of an airport hazard area not to exceed one mile from the airport boundary.
