The Town of North Andover is hereby divided into zoning districts designated as follows:

The zoning districts established by this bylaw are bounded as shown on a map dated May 12, 1972, as the same may be adopted by the Town, and as it may hereafter be amended. Said map accompanies and is hereby made a part of this bylaw. Any land area not designated upon said map as being within another zoning district shall be within the Residence 2 District. The Floodplain District is defined as all areas so designated on maps entitled "Flood Insurance Rate Maps" (FIRMs) and Flood Boundary and Floodway Map dated June 2, 1993, and as they may hereafter be amended, on file with the Town Clerk, incorporated by reference herein.

Where uncertainty exists as to the boundaries of any of the aforesaid districts as shown on the Zoning Map, the Building Inspector shall determine the location of such boundaries. In reaching any such determinations, the Building Inspector may properly rely upon the accuracy of the land area descriptions appearing in the Zoning Bylaw adopted by the Town in 1956, and as thereafter amended, insofar as any of them may be pertinent thereto.

Historic Districts established pursuant to the provisions of MGL Chapter 40C, as may be from time to time amended, shall be indicated on the Zoning Map by appropriate symbol.
