20.06.050   District boundary determination.
   A.   Where indicated, district boundaries are approximately street, alley, or lot lines and said lines are determined to be the boundaries of the district. Otherwise, the boundaries shall be determined by the dimensions shown on the official zone map. In the absence of a dimension, the boundary shall be determined by use of the scale shown on the map.
   B.   A street, alley, railroad or railway right-of-way, watercourse, drainage channel, or body of water included on the zone map shall, unless otherwise indicated, be included within the zone of adjoining property on either side thereof; and where such street, alley, watercourse, drainage channel, or body of water serves as a boundary between two or more different zoning districts, the centerline of such right-of-way, watercourse, channel, or body of water shall be considered the boundary between zoning districts.
   C.   In the event that a vacated street, alley, right-of-way, or easement was the boundary between two districts, the new zoning district boundaries shall be at the new property line.
   D.   Where uncertainties exist, the commission shall, by written decision, determine the location of the district boundary.
