Said "districts" are bounded and defined as shown on a map entitled the "Town of Pound Ridge, New York, Zoning Map"[1] which, with all explanatory matter thereon, is adopted and made a part of this chapter, and on such supplementary Zoning Maps as may be adopted by the Town Board and made a part of this chapter by express reference.
[1]
Editor's Note: Said map is included in the pocket at the end of this volume.
Where "districts" are referred to as "more restrictive" or "less restrictive," the designation shall refer to the order in which the "districts" are named above, the first named being the most restrictive.
Where uncertainty exists as to the locations of any boundaries shown on the Zoning Map, the following rules shall apply:
A. 
"District" boundary lines are intended to follow "streets," rights-of-way, watercourses or "lot lines" or to be parallel or perpendicular thereto, unless such "district" boundary lines are fixed by dimensions, as shown on the Zoning Map.
B. 
Where "district" boundaries are indicated as approximately following "streets," rights-of-way or watercourses, the center lines thereof shall be construed to be such boundaries.
C. 
Where "district" boundaries are so indicated that they approximately follow the edge of lakes, ponds, reservoirs or other bodies of water, the mean high water lines thereof shall be construed to be the district boundaries, except that the regulations of the most restrictive district on the edge of such a body of water shall apply to the area within the mean high water line and the body of water thereof.
D. 
Where "district" boundaries are so indicated that they approximately follow "lot lines," such "lot lines" shall be construed to be such boundaries.
E. 
In unsubdivided property or where a "district" boundary divides a "lot," the location of any such boundary, unless the same is indicated by dimensions shown on said map, shall be determined by the "use" of the map scale shown thereon.
F. 
If the "district" classification of any land is in question, it shall be deemed to be in the most restrictive adjoining "district."
G. 
In the Planned Business A Zoning "District," the location of the boundaries of "building areas" is shown on the supplementary Zoning Map entitled "Planned Business A Zoning District, showing Building Areas and Parking Areas," 1966, as amended. The distances shown on this map shall fix the boundaries of the "building area" in relation to the "lot lines" of the affected property as they existed on the date of the adoption of the "Planned Business A Zoning "District."
Where a "lot" lies in two or more zoning "districts," any "building" or land "uses" established thereon shall comply with the regulations of the "district" in which said "building" or "use" is located. "Uses" permitted in one "district" may not extend into another "district" where they would not otherwise be permitted. Dimensional requirements shall be measured from "lot lines" and not zoning "district" lines.
