A. Zone boundaries, unless otherwise indicated, are lot lines or the center line of streets and alleys as shown on the official Zoning Map. Where the street layout actually on the ground varies from that shown on the Zoning Map, the designations shown on the map shall be applied to the streets as actually laid out so as to carry out the intent and purposes of this title. Where the location of the zone boundaries are shown on the Zoning Map to be other than street, alley, or lot lines, the depth of the zone shall be the same as that measured by scale on the official Zoning Map.

B. If a boundary line cuts a property having a single ownership as of record at the time of the passage of the ordinance codified in this title, the property may be used in conformance with the zoning designations and boundaries as shown on the official Zoning Map. A property owner in this case may appeal to the Planning Agency for a determination as to which zone would appropriately apply to the entire property.
