§ 156.17  LAND USE SAFETY ZONING.
   (A)   Safety Zone purposes.  Safety Zone shall be established for the following purposes:
      (1)   To carry out the purposes of this chapter;
      (2)   To restrict uses which may be hazardous to the operational safety operating to and from the airport.
      (3)   To limit population and building density in the runway approach areas, and thereby to create sufficient open space so as to protect life and property in case of accident.
   (B)   Safety Zone boundaries.  The following safety zones are hereby established:
      (1)   Safety Zone A.  All land in that portion of the approach zones of runway 11/29 and runway 17, as set forth in § 156.16(A) which extends outward from the end of the primary surface a distance equal to two-thirds of the planned length of the runway. These distances shall be:
         (a)   4,733 feet for runway 11/29.
         (b)   3,333 feet for runway 17.
         (c)   For runway 35, all land in the approach zones north of the south right-of-way of I-90.
      (2)   Safety Zone B.  All that land in that portion of the approach zones of runway 11/29 and runway 17, as set forth in § 156.16(A), which extends outward from Safety Zone A, a distance equal to one-third of the planned length of the runway. This distance shall be:
         (a)   2,367 feet for runway 11/29.
         (b)   1,667 feet for runway 17.
      (3)   Safety Zone C.  All that land which is enclosed within the perimeter of the horizontal zone,  as set forth in § 156.16(A), and which is not included in Zone A or Zone B.
   (C)   Use restrictions.
      (1)   General.  Subject at all times to the height restrictions set forth in § 156.16(B), no use shall be made of any land in any of the safety zones set forth in division (B) of this section, which:
         (a)   Creates or causes interference with the operations of radio or electronic facilities of the airport, or with radio or electronic communications between the airport and aircraft.
         (b)   Makes it difficult for pilots to distinguish between the airport lights and other lights.
         (c)   Results in glare in the eyes of pilots using the airport.
         (d)   Impairs visibility in the vicinity of the airport.
         (e)   Otherwise endangers the landing, taking off, or maneuvering of aircraft.
      (2)   Zone A.  Subject at all times to the height restrictions set forth in § 156.16(B), and to the general restrictions contained in this division (C), areas designated as Zone A areas shall contain no buildings or temporary structures, exposed transmission lines or other similar above-ground structural hazards. It 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: agriculture, light outdoor recreation (non-spectator), cemeteries and auto parking.
      (3)   Zone B.  Subject at all times to the height restrictions set forth in § 156.16(B), and to the general restrictions contained in this division (C), areas designated as Zone B shall be restricted in use as follows:
         (a)   Each use shall be on a site whose area shall be not 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 not more than one building plot upon which any number of structures may be erected.
         (d)   A building plot shall be a single, uniform and non-contrived area, whose area shall not exceed the following minimum ratios with respect to the total site area:
 
Site Area (Acres)
