Where uncertainty exists as to the boundaries of any of the aforesaid districts on said map, the following rules shall apply. Where more than one of the rules are applicable in any given situation, the first enumerated rule shall prevail:

A. Where a district boundary line is shown by a specific dimension, such specific dimension shall control.

B. Where a district boundary line is located within or along a street, alley, right-of-way, or waterway, the district boundary line shall be deemed to be the center of such street, alley, right-of-way, or waterway, or extension therefrom.

C. Where a district boundary line is shown as approximately following platted lot lines, the district boundary line shall be deemed to coincide with such platted lot lines.

D. If none of the above rules is found to be sufficient to resolve the question, the zoning administrator:

1. Shall, using a scaled rule, measure a line drawn on the map, take note of the dimensions and record such dimensions on the map, thus establishing for future reference the location of said boundary in a manner to be consistent; or

2. May make a decision, based on his knowledge and understanding of this title, specifically determining the location of the boundary in question. Any such decision becomes fixed unless amended by the city council, and a reference shall be entered on the map showing the date such decision was made. The zoning administrator shall keep on permanent file any such decision which may be altered or amended by the city council. (Ord. 523 § 1(part), 1989)
