Where uncertainty exists as to the boundaries of any zone shown upon the Zoning Map, the following rules shall apply:
   .010   Following Existing Features.  Where the boundaries are indicated as approximately following street, alley or legal lot lines, such lines shall be construed to be the zone boundaries.  Any portion of a property that is used for a private street shall have the same zoning as the entire parcel.
   .020   Division of a Lot.  In the case of unsubdivided property and where a zone boundary divides a lot, the location of such boundaries, unless they are indicated by dimensions, shall be determined by use of the scale appearing on the Zoning Map.
   .030   Vacation of Street or Alley.  Where a public street or alley is officially vacated or abandoned, the area comprising the vacated street or alley shall acquire the classification of the property to which they revert.  If a vacation results in an independent lot, such lot shall acquire the zoning of the adjacent property.
   .040   Property Without Zoning.  If a property is not designated in any zone on the Zoning Map, it shall be deemed to be in the "T" (Transition) Zone described in Chapter 18.14 (Public and Special-Purpose Zones).  (Ord. 5920 § 1 (part); June 8, 2004.)
