Primary Districts. The boundaries between districts are, unless otherwise indicated, either the center line of streets, rights-of-way, or watercourses, 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, right-of-way, or watercourse, for any portion of its length, the district so indicated shall be construed to apply to the entire bed of such street, right-of-way, or watercourse, 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 line of a street, right-of-way, or watercourse, 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 as of the effective date of this chapter, 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 specified by figures on the Zoning Map, shall be determined by the use of the scale appearing on said map.
D.
Where dimensions 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. Where scaled distances do not agree with such figures, the dimensions shall control.
