All land in the City of Oswego shall fall within one of the established land use control districts as shown on the City of Oswego Zoning Map, hereinafter "Zoning Map," which accompanies this chapter. The zoning districts are shown, defined and bounded on the Zoning Map. The Zoning Map is hereby made a part of this chapter and shall be on file in the office of the City Clerk.
Where uncertainty exists with respect to the boundaries of any of the districts as shown on the Zoning Map, the following rules shall apply:
A. 
Where district boundaries are indicated as approximately following the center lines of streets or highways, street lines or highway right-of-way lines, such lines shall be construed to be coincident with said boundaries.
B. 
Where district boundaries are so indicated that they are approximately parallel to center lines or right-of-way lines of streets or highways, such district boundaries shall be construed as being parallel thereto and at such distance therefrom as is indicated on the Zoning Map. If no such distance is given, such dimension shall be determined by the use of the scale shown on said Zoning Map.
C. 
Where district boundaries are so indicated that they follow the lot lines approximately, said district boundaries shall be construed to be coincident with such lot lines.
D. 
Where the boundary of a district follows a railroad line, such boundary shall be construed to be located midway between the main tracks of said railroad line.
E. 
Where the boundary of a district follows the Oswego River or a stream, such boundary shall be construed to be at the midpoint, or coincident with the center line, of the river or of such stream.
F. 
Where the boundary of a zoning district follows the Lake Ontario shoreline, the district boundary shall be construed to be such shoreline coincident with the limits of the City of Oswego; but if in the future water areas are filled and the shoreline advanced or if docks, piers and such other structures attached directly to the shoreline, or not directly attached but forming part of the physical facilities located on the shore, are constructed, such zoning district shall include these areas and facilities.
G. 
In all other cases, where dimensions are not shown on the Zoning Map, the location of the boundaries shown on said map shall be determined by use of the scale appearing thereon.
If a lot is divided by a zoning district boundary, the respective district regulations shall apply to each portion of the lot, except that:
A. 
The regulations of the more restrictive district may be applied to the entire lot.
B. 
The Board of Appeals may establish requirements within the intent of this chapter which represent a compromise between the requirements of the districts involved and which are approximately proportional to the area of the lot that lies within each different district. In no case shall such requirements be less restrictive than the regulations in the least restrictive district.
