B. 
The Zoning Map, together with all boundaries, notations and other data and explanatory matter shown thereon, is part of this Zoning Bylaw.
C. 
The Zoning Map, including any amendments and any future Zoning Maps which may be adopted from time to time, shall be kept on file in the office of the Town Clerk.
For purposes of interpreting the Zoning Map, the following rules apply:
A. 
Where a district boundary line appears to follow a street or railroad right-of-way, watercourse, or other body of water, the district boundary coincides with the center line thereof.
B. 
Where a district boundary line appears to run parallel to a street or railroad right-of-way, the district boundary runs parallel to the sideline of the right-of-way at such distance therefrom as indicated on the Zoning Map. Where a district boundary line appears to run parallel to a river, stream or other body of water, the district boundary runs parallel to the top of the bank or the shoreline at such distance therefrom as is indicated on the Zoning Map. If no numeric dimension is indicated on the Zoning Map, such distances shall be determined by using the scale shown on the Zoning Map.
C. 
Unless otherwise indicated by a specific notation on the Zoning Map, a district boundary that appears to follow a property line will coincide with that property line.
D. 
Where a district boundary line is indicated as a specific elevation, the elevation is the distance above mean sea level, based on Massachusetts Geodetic Datum of 1982 unless otherwise specified on the Zoning Map or elsewhere in this Zoning Bylaw.
E. 
In any case not covered by the other provisions of this section, the location of a district boundary line shall be determined by the distance in feet from other lines as specified on the Zoning Map or, if the distance is not specified, then by using the scale indicated on the Zoning Map.
F. 
When a base district boundary line divides a lot at the time such boundary line is adopted, the use regulations for either district may be extended up to 50 feet into the portion of the lot in the other district, provided the lot has frontage on a street in the less restrictive district. The Zoning Board of Appeals may, by special permit, allow such extension to be increased to a maximum of 200 feet.
