All districts herein referred to are located and bounded as shown on a map entitled "Town of Norwood, Mass., Zoning Map Supplementary to and Changing Original Zoning Map dated November 1926 and showing alteration of district boundaries under Amendment to Section 17 of the Zoning Bylaws as adopted June 15, 1928," dated April 27, 1935, bearing the signatures of the Planning Board and filed in the office of the Town Clerk, together with any and all amendments thereto subsequently adopted by the Town. Said map, together with all explanatory matter thereon, and amendments thereto, shall be deemed to accompany and be part of these Bylaws.
2.3.1. 
Boundary Determination. The location of the boundary lines of the districts shown upon the Zoning Map shall be determined as follows:
1. 
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.
2. 
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.
3. 
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).
4. 
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.
5. 
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.
2.4.1. 
Lot Split by District Boundary Line. Where a district boundary line divides any lot existing at the time such boundary line is adopted, the lot shall be considered as if divided by that boundary into separate portions, with development of each portion of the lot to meet all requirements of the district in which it is located (including lot area, frontage, and yards) within that district. However, the lot shall be considered as a whole in the case of a use allowed in both districts, in which event the dimensional regulations of the district in which the majority of the lot frontage lies shall apply to the entire lot.
2.4.2. 
Lot Split by Town Line. When a lot in one ownership is situated in part in the Town of Norwood and in part in an adjacent municipality, the provisions of these Bylaws shall be applied to that portion of the lot lying in the Town of Norwood in the same manner as if the entire lot were situated therein.
