Where appropriate and unless otherwise indicated, zoning district boundaries shown on the Zoning Map are the center lines of streets, power line rights-of-way, the middle of the channel of waterways or other bodies of water or the Town boundary line. Where a boundary is so indicated that it parallels the center line of a street, such boundary shall be considered to be parallel thereto at the distance therefrom shown on the Zoning Map. Any boundary within 10 feet of a property line shall be considered to coincide with such property line. Where no distance is stated on the Zoning Map, the distance shall be determined by the use of the scale on the map. In any instance where there is doubt as to the location of a zoning district boundary, the Zoning Administrator shall determine the location of such boundary, consistent with the intent of this chapter and the Zoning Map. Boundaries defined by the overlay Wetland District are excluded from this section.
