In order to carry out the purpose of this code, the city of American Fork, Utah, is hereby divided into zones as follows:

(Ord. No. 5-81-2-3-1; Ord. No. 85-08-19; Ord. No. 88-12-13; Ord. No. 93-06-12; Ord. No. 05-05-18; Ord. No. 06-02-08; Ord. No. 07-01-04; Ord. No. 2010-12-25, § 1, 12-14-2010; Ord. No. 2011-04-10, 4-12-2011)

The location and boundaries of each of the zones are shown on the Official Zone Map of American Fork, Utah, and said map is hereby declared to be an official record and a part of this code and said official zone map and all notations, reference and other information shown thereon shall be as much a part of this code as if the matters and other information set forth by said map were fully described herein. Said official zone map shall be identified by the signature of the mayor of the city, attested to by the city recorder, and placed in the office of the city recorder. Whenever amendments or changes are made in zone boundaries, such amendments or changes shall be made by the zoning administrator on the official zone map promptly. No amendment or change shall become effective until after it has been properly noted and attested to on the official zone map. No changes of any nature shall be made in the official zone map except in conformity with the procedure set forth in this code. Any unauthorized change of whatever kind by any person or persons shall be considered a violation of this code and punishable as provided in this code. Regardless of the existence of purported copies of the official zone map which may from time to time be made or published, the official zone map which shall be located in the office of the city recorder shall be the final authority in determining current status.

Where uncertainty exists with respect to the boundaries of various zones, the following rules shall apply:

1. Where the indicated boundaries on the zone map are approximately street or alley lines, said street or alley shall be construed to be the zone boundaries.
2. Where the indicated boundaries are approximately lot lines, said lot lines shall be construed to be the zone boundaries unless otherwise indicated.
3. Where land has not been subdivided into lots and blocks the zone boundaries shall be determined by use of the scale of measurement shown on the map.
4. Where other uncertainty exists the board of adjustment shall interpret the map.

In establishing the zones, the boundaries thereof, and other regulations and restrictions applying within each of the zones, due and careful consideration was given, among other things, to the suitability of the land for particular uses, and to the character of the zone, with a view of conserving the value of buildings and encouraging the most appropriate use of land throughout the city.
