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

   A.   Where the intended boundaries on the official zone map are approximately street or alley lines, said street or alleys shall be construed to be the zone boundaries;

   B.   Where the indicated boundaries are approximately lot lines, said lot lines shall be construed to be the zone boundaries unless otherwise indicated;

   C.   Where land has not been subdivided into lots, the zone boundary shall be determined by the use of the scale of measurement shown on the official zone map;

   D.   Where other uncertainty exists, the board of adjustment shall interpret the official zone map.

(Prior code § 17.20.030)
