10-20-6: AIRPORT ZONES AND DISTRICT REGULATIONS:
In order to carry out the provisions of this chapter, there are hereby created and established six (6) zones as shown on the airport zoning map, consisting of one sheet, attached to ordinance 2007-11, and made a part of this chapter by reference. For the purpose of this chapter, the lands and waters within three (3) statute miles from the boundaries of the airport are divided into six (6) districts defined as follows:
   A.   Zone 1 - Airport District: The "airport district" is defined as all those lands controlled by the airport, either by fee ownership or by an easement, and intended to be used for airport purposes. The airport district is created to encompass areas that, due to the operation of aircraft, could be exposed to excessive noise, are within the aircraft approach and departure areas, or are in areas which are exposed to a greater risk of aircraft crashes (crash hazard area). The airport district is established to protect the approaches to the airport from incompatible land uses, and to preserve the airport's ability to serve its present and future air transportation needs. Any new building, or expansion, alteration, or enlargement of any existing building, structure, or property within this zone must be approved by the department. Any construction, expansion, alteration, or enlargement must receive a favorable airspace review from FAA and the Wisconsin bureau of aeronautics. The boundaries of the airport district are shown on the airport zoning map.
      1.   Permitted Uses And Structures: Only uses and structures that are directly related to and necessary for the function and operation of the airport.

   B.   Zone 2 - Runway Approach And Departure District: The purpose of this district is to establish land use requirements in areas that are typically overflown by aircraft during takeoff and landing maneuvers, and hence could be subjected to excessive noise and greater risk of aircraft crashes.
      1.   Permitted Uses:

Any use that may be susceptible to being adversely affected by loud and extensive noise or would interfere with the safe operation of the airport.
Hospitals, churches, schools, theaters, amphitheaters, stadiums, athletic fields, and campgrounds, or other places of public assembly.
Landfills, garbage dumps, offal dump sites, and other similarly licensed or titled facilities used to process, bury, store, or otherwise dispose of waste, trash, refuse, or dredge material that would attract birds or rodents.

         c.   Lot Density: The maximum lot coverage allowed is fifty percent (50%) or as allowed by the underlying municipal jurisdiction, whichever is more restrictive.
   C.   Zone 2A - Modified Runway Approach And Departure District 2A: The purpose of this district is to establish land use requirements similar to, but less restrictive than zone 2, in areas that are overflown by aircraft during takeoff and landing maneuvers, and hence could be subjected to occasional excessive noise and risk of aircraft crashes.
      1.   Permitted Uses:
