Where the boundary lines are shown upon said map within the street lines of public or private streets or ways, the center line of such streets or ways shall be the boundary lines.

Where the boundary lines are shown approximately upon the location of existing property or lot lines, and the exact location of boundary lines is not indicated by means of figures, distance or otherwise, then the property or lot lines shall be the boundary lines.

Boundary lines located outside of such street lines and shown approximately parallel thereto shall be regarded as parallel. Figures placed upon the map between the boundary lines and street lines are measured at right angles to the street line unless otherwise indicated.

Any lot, the frontage of which is bisected by any zone, as shown on the Zoning Bylaw Map, shall be deemed to be in the zone in which the majority of the lot lies. In the event that any lot so bisected should be equally divided, the lot shall be placed in the zone recommended by the Planning Board.

In all cases which are not covered by the provisions of this section, the location of boundary lines shall be determined by the distance in feet, if given, from other lines upon said map, by the use of identifications as shown on the map or, if none are given, then by the scale of the map.

Whenever any uncertainty exists as to the exact location of a boundary line, the location of such line shall be determined by the Inspector of Buildings; provided, however, that any person aggrieved by his decision may appeal to the Board of Appeals.
