Generally. The district boundary lines, unless shown otherwise, are intended generally to follow street center lines, railroad right-of-way boundary lines or their center lines, other similar right-of-way lines, or lot lines or boundaries of subdivisions, or Village boundary lines, all as shown on the Zoning Map. Where a district boundary line does not follow such a line but is shown parallel to such a line on the Zoning Map, the distance between the parallel lines shall be as dimensioned on the Zoning Map. Such dimensions shall be construed to read from the outside edge of all rights-of-way rather than from their center lines.

Inaccurate street layouts. Where the street layout actually on the ground varies from the street layout as shown on the Zoning Map, the designation shown on the mapped streets shall be applied in such a way as to carry out the purpose and intent of the Zoning Map for the particular area in question.

Scaling. When the location of a district boundary line cannot be otherwise determined, the determination thereof shall be made by scaling the distance on the Zoning Map from a line of known location to such district boundary line.

Boundary line division of lot. Where a district boundary line divides a lot in a single ownership at the effective date of this chapter or any subsequent amendment thereto, the Board of Appeals may permit the less restrictive use to extend to the entire lot, but not more than 30 feet beyond the boundary line of the district in which such use is authorized, pursuant to § 160-45.

Interpretation. If there is doubt as to the location of a district boundary line in a particular instance, the location of such district boundary line shall be determined by the Building Inspector. An appeal from such determination may be taken to the Board of Appeals pursuant to § 160-43.
