Inasmuch as the character and type of development throughout the Town is predominantly rural residential, supplemented by a limited amount of business and service establishments for the convenience of local residents, and based upon the rugged nature of the Town's topography, and the policies expressed in the adopted Town Plan of Development, the Town of Weston is hereby divided into the following districts:
A. 
R-2A, Two-Acre Residential and Farming District.
B. 
NSC, Neighborhood Shopping Center District.
The boundaries between districts are hereby established as shown on the map entitled "Zoning Map, dated November 19, 1970" which accompanies these regulations and is on file in the office of the Town Clerk. Said map and all explanatory matter thereon are hereby adopted and made a part of these regulations.
District boundary lines are intended to follow roads, rights-of-way, watercourses, or lot lines, or be parallel or perpendicular thereto, unless such boundary lines are fixed by dimensions, as shown on the Zoning Map.
Where a district boundary line divides a parcel of land under single ownership of record, the regulations specified herein for each district shall apply only to those portions of the parcel within such district.
