(Ord., 9-5-2006; amd. Ord. 25-01, 2-18-2025)

   A.   It is hereby found that an airport hazard endangers the lives and property of users in the Brigham City airport and of occupants of land or to property in its vicinity. Such hazard also reduces the size of the area available for landing, taking off and maneuvering of aircraft, and it tends to destroy or impair the utility of the Brigham City municipal airport and the public investment therein.

   B.   Accordingly, it is declared that:

      1.   The creation or establishment of an airport hazard is a public nuisance and an injury to the region served by the Brigham City municipal airport;

      2.   It is necessary in the interest of public health, public safety and general welfare that the creation or establishment of an airport hazard be prevented; and

      3.   The prevention of those hazards should be accomplished, to the extent legally possible, by the exercise of the police power without compensation.

   C.   It is further declared that both the prevention of the creation or establishment of airport hazards and the elimination, removal, alteration, mitigation or marking and lighting of existing airport hazards are public purposes for which political subdivisions may raise and expend public funds and acquire lands or interests in land.

(Ord., 9-5-2006; amd. Ord. 25-01, 2-18-2025)

   A.   These regulations reinforce specific provisions in the Brigham City municipal airport master plan (May 2, 1996), as amended, and the Brigham City general plan (January 15, 1998), as amended.

   B.   The boundary of any officially recognized airport overlay zones shall be as it appears on a map and/or other documents approved by the town council.

   C.   Note that only two (2) overlay zones apply to the town, airport influence area (AIA) and traffic pattern zone (TPZ).
