Where uncertainty exists with respect to the boundaries of the
various Districts as shown on the Zoning Map, the following conditions
shall apply:
A. District boundaries are meant to and shall be considered to follow
street, alley or lot lines, or lines parallel or perpendicular thereto,
unless such boundaries are otherwise shown on the Zoning Maps.
B. Where a boundary line is shown within a street, alley or navigable
or nonnavigable stream, it shall be intended to follow the center
line of such street, alley or stream. Should the actual location of
such street, alley or stream vary from the location as shown on the
Zoning Map, then the actual natural location shall control.
C. Where a boundary line is shown as being located a specific distance
from a street line or other physical feature, then this distance shall
control.
D. In unsubdivided property, unless otherwise indicated, a District
boundary line on the Zoning Map shall be determined by the use of
the scale on the Zoning Map.
E. Wherever any road, alley or other public way is abandoned by official
action as provided by law, the Zoning Districts adjoining the side
of such public way shall be automatically extended, depending on the
side or sides to which such lands revert, to include the right-of-way
of the public way thus vacated, which shall thenceforth be subject
to all regulations of the extended District or Districts.
