Streets and Similar References. Where a boundary line is shown as following a street, railroad, or utility transmission line, the boundary shall be the centerline thereof unless otherwise indicated. Where a boundary line is shown as following or parallel to a street, utility, property or other line, said other line shall be deemed to be located as it existed on the date of the establishment of the zoning boundary line which is referred to it, and any subsequent changes in said other line (as through a street widening, relocation or abandonment, or a change of property) shall not alter the location of the zoning boundary line in question.

Property Lines. Where a boundary line is shown approximately on the location of a property or lot line and the exact location of the boundary line is not indicated by means of a figure, dimension, or otherwise, then the property or lot line shall be the boundary line.

Parallel Lines. Where a boundary line is shown outside of the lines of a street or railroad and approximately parallel thereto, such boundary line shall be deemed parallel to the exterior line thereof; and where a figure is placed upon the map between such boundary line and the street or railroad, it indicates the distance in feet of such boundary line from such exterior line (measured at right angles thereto, unless otherwise indicated).

Other Cases. In any case not otherwise covered by the provisions of this Section 2.3.1, the location of a boundary line shall be determined by the distance in feet, if given, from the other lines on the map or, if distances are not given, by the scale of the map.

Uncertainty. Wherever any uncertainty exists as to the exact location of a boundary line, the location of such a line shall be as determined by the Inspector of Buildings, with the advice and assistance of the Town Engineer, who shall file a written report of his finding with the Town Clerk. Such finding shall be subject to the right of appeal in the manner hereinafter provided.
