In the case of the Flood Hazard Overlay District, rules for interpretation of district boundaries are contained in Article
XI, §
525-51. For all other districts, the boundaries between districts are, unless otherwise indicated, either the center lines of streets, alleys, watercourses, and rights-of-way of power lines, and other public utilities. 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 public utility, for any portion of its length, the district so indicated shall be construed to apply to the entire bed of such street, alley, 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-line of a street, lane, or watercourse, or right-of-way of a public utility, such center-line shall be construed to be such boundary.
B. Where a district boundary is indicated as approximately following a lot line or other property line, such lot line 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 equivalent to the number of feet so indicated. Where scaled distances do not agree with such figures, the figures shall control.
