The text
When uncertainty exists as to the exact boundaries of a zone, the following shall apply: A.
A street, alley, railroad right-of-way, watercourse channel, or other right-of-way shall be included within the zone of the adjoining property.
B.
When the zone district boundary is or approximately follows a street, alley, railroad right-of-way, watercourse, or other right-of-way, the centerline of that right-of-way shall be considered as the boundary.
C.
When the zone boundaries approximately follow lot lines, section lines, or city limits, these lines shall be considered the boundaries.
D.
Where the boundary splits the lot or parcel, or uncertainty still exists, the exact boundary shall be determined by written decision of the planning commission.
E.
When the street, alley, or right-of-way that serves as a zone boundary is vacated, the new zone boundary shall be at the new property line. Where the vacation does not result in a new property line, the zone boundary shall be determined by written decision of the planning commission.
F.
Areas annexed to the city shall come into the city at their existing zone designation. if there is no prior designation, the planning commission shall determine the nearest comparable zone for the area. The zoning map shall then be amended to show the new city limits and zone.
