The boundaries between districts are, unless otherwise indicated, either the center lines of streets, lanes, watercourses, property lines and rights-of-way of power lines, railroads and other public utilities or such lines extended or lines parallel thereto. Where the boundaries of a single district are indicated as including directly opposite sides of a street, lane, lake or watercourse or right-of-way of a power line or other public utility or any portion of its length, the district so indicated shall be construed to apply to the entire bed of such street, lane, lake or watercourse or right-of-way of such power line, railroad or other public utility lying within such portion of its length. Where uncertainty exists as to the location of any said boundaries as shown on the Zoning Map, the following rules shall apply:
A. Where a district boundary is indicated as approximately following the center lines of a street, lane, lake or watercourse or right-of-way of a power line or other public utility, such center line 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 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 distance therefrom equivalent to the number of feet so indicated, unless otherwise specified. Where scaled distances do not agree with such figures, the figures shall control.
