Except for the Floodplain Overlay District and Water Supply Protection District, the boundaries of these districts are located and bounded as shown on a map entitled "Town of Northfield, Massachusetts Zoning Map," as most recently amended by Town Meeting, on file in the office of the Town Clerk. Said map, with the boundaries of the districts and all explanatory matter thereon, is hereby made a part of this bylaw.[1]

The Floodplain Overlay District shall be located and bounded as shown on the map described in § 200-10.1 herein, which map is incorporated in and made a part of this Zoning Bylaw.

The Water Supply Protection District shall be located and bounded as shown on maps described in § 200-10.2 herein, which maps are incorporated in and made part of this Zoning Bylaw.

Where the boundary lines on the Zoning Map or the Water Supply Protection District Map are within the street lines of public or private ways, the center lines of such ways shall be the boundary lines.

Where the boundary lines are shown approximately on the location of property or 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.

Where the boundary lines are located outside of such street lines and shown approximately parallel thereto, they shall be regarded as parallel to such street lines, and dimensions shown in figures placed upon said map between such boundary lines and street sidelines are the distances in feet of such boundary lines from such street sidelines, such distances being measured at right angles to such street lines unless otherwise indicated.

Where the location of boundary lines is uncertain, it 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.

Where boundary lines are contour lines, they are at an indicated elevation above the datum which is mean sea level of the United States Geological Survey.
