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 centerline or street line of streets, the centerline or alley line of alleys, or the centerline or right of way line of highways, such lines shall be construed to be such district boundaries.
B. Where district boundaries are so indicated that they are approximately parallel to the centerline of street lines of streets, the centerlines or alley lines of alleys, or the centerlines or right of way lines of highways, such district boundaries shall be construed as being parallel thereto and such distance therefrom as indicated on the zoning map. If no distance is given, such dimension shall be determined by the use of the scale shown on the zoning map.
C. Where district boundaries are indicated as approximately following lot lines, such lot lines shall be construed to be said boundaries.
D. Where the boundary of a district follows a railroad line, such boundary shall be deemed to be located midway between the main tracks of said railroad line.
E. Where the boundary of a district follows a stream, lake or other body of water, said boundary line shall be construed to be at the limit of the jurisdiction of the city, unless otherwise indicated.
F. All areas within the corporate limits which are underwater and are not shown as included within any district shall be subject to all of the regulations of the district which immediately adjoins the water area. If the water area adjoins two (2) or more districts, the boundaries of each district shall be construed to extend into the water area in a straight line until they meet the other district.
G. Any areas shown on the zoning map as a park, playground, school, cemetery, water, street or right of way, shall be subject to the zoning regulations of the district in which they are located. In case of doubt, the zoning regulations of the most restricted adjoining district shall govern.
H. In every case where property has not been specifically included within a district, or where territory has become a part of the city by annexation, the same shall automatically be classed as lying and being in the A residential district until such classifications have been changed by an amendment to this title as provided by law.
I. Whenever any street, alley or other public way is vacated in the manner authorized by law, the zoning district adjoining each side of such street, alley or public way shall be automatically extended to the center of such vacation and all area included in the vacation shall then be subject to all regulations of the extended districts.
