The districts set forth above are shown on the
Official Zoning Map, which, together with all explanatory material
thereon, is hereby adopted by reference and declared to be part of
this chapter. The Official Zoning Map shall be identified by the signature
of the Chairperson of the Planning Board and attested by the Town
Clerk bearing the Seal of the town. The Official Zoning Map is included
as originally dated May 1963 and as most recently amended.
Where uncertainties exist as to the boundaries
of districts as shown on the Official Zoning Map, the following shall
apply:
A. Where the boundary lines are shown upon said map as
approximately following the street lines of public and private ways
or railways, the center lines of such ways shall be the boundary lines.
B. Where the boundary lines are shown approximately on
the location of property lot lines and the exact location of property,
lot or boundary lines is not indicated by means of dimensions shown
in figures, then the property or lot lines shall be the boundary lines.
C. Boundary lines located outside of street lines and
shown approximately parallel thereto shall be regarded as parallel
to such street lines, and dimensions shown in figures placed upon
said map between such boundary lines and street lines are the distance
in feet of such boundary lines from such street lines, such distances
being measured at right angles to such street lines unless otherwise
indicated.
D. In all cases which are not covered by other provisions
of this section, the location of boundary lines shall be determined
by the distance in feet, if given, from other lines upon said map,
by the use of identifications as shown on the map or by the scale
of the map.
E. Where the district boundary line follows a stream,
lake or other body of water, said boundary line shall be construed
to be at the thread or channel of the stream or at the limit of the
jurisdiction of the Town of Chelmsford, unless otherwise indicated.
F. Where a district boundary line divides any lot existing
at the time such line is adopted, the regulations of any district
in which the lot has frontage on a street may be extended by special
permit from the Board of Appeals not more than 30 feet into the other
district.
G. Where physical or cultural features existing on the
ground are at variance with those shown on the Official Map or in
other circumstances not covered by the above subsections, the Board
of Appeals shall interpret the district boundaries.
