The boundaries between districts are, unless otherwise indicated, either the centerlines of streets, watercourses, property lines, rights-of-way of power lines, railroads or other public utilities. The following rules shall apply where uncertainty exists as to the location of any boundary on the Zoning Map:
A.
Where a district boundary is indicated as approximately following the centerlines of a street, watercourse or rights-of-way of a utility, such centerline shall be construed to be such boundary.
B.
Where a district boundary is indicated as approximately following a lot or other property line, such lot or property line shall be construed to be such boundary.
C.
Where a district boundary divides a lot or runs through undivided property, the location of such boundary, unless otherwise specified by figures on the Zoning Map, shall be determined by the use of the scale appearing on the said map.
D.
Where figures are shown on the Zoning Map between a street and a district boundary, they shall indicate that the district boundary runs parallel to the street line at a given distance. Where scaled districts do not agree with such figures, the figures shall control.
