Where uncertainty exists as to the boundary of any zone, the following rules shall apply:
A. Wherever the zone boundary is indicated as being approximately upon the centerline of a street, alley or block, or along a property line, then unless otherwise definitely indicated on the map, the centerline of such street, alley, or block, or such property line, shall be construed to be the boundary of such zone.
B. Wherever such boundary line of such zone is indicated as being approximately at the line of any river, irrigation canal, or other waterway, or railroad right of way, or public park or other public land, or any section line, then in such case of the center of such stream, canal, or waterway or of such railroad right of way, or the boundary line of such public land or such section line shall be deemed to be the boundary of such zone.
C. Where such zone boundary lines cannot be determined by the above rules, their location may be found by the use of the scale appearing upon the map.
D. Where the application of the above rules does not clarify the zone boundary location, the board of zoning adjustment shall interpret the map.
