If a zone boundary as shown on the official zoning map divides a lot between two zones, the entire lot shall be deemed to be in the zone in which the greater area of the lot lies; provided that, this adjustment involves a distance not to exceed 20 feet from the mapped zone boundary. Except as otherwise described, zone boundaries follow property lines, street rights-of-way or city limit lines. (Ord. 80-2, passed 06/14/2010)
