§ 3. Rules where map designation uncertain.

Where uncertainty exists with respect to the boundaries of the various zoning districts as shown on the zoning district map, the following rules shall apply:

A.

The district boundaries are either streets or alleys, highway rights-of-way, railroad rights-of-way, waterways, lot lines, property lines, quarter section lines, half section lines, or full section lines, unless otherwise shown. Where the designation on the zoning district map indicates the various districts are approximately bounded by street or alley lines, the street or alley shall be constructed to be the boundary of the district.

B.

Where the zoning district boundaries are not otherwise indicated and where the property is divided into blocks and lots, the district boundaries shall be lot lines. Where the designation on the zoning district map indicates that the various districts are approximately bounded by lot lines, the lot lines shall be the boundary of such district unless the boundaries are otherwise indicated on the map.

C.

In unsubdivided property, the zoning district boundary line on the zoning district map may be determined by use of the scale contained on the map.

D.

Whenever any street, alley, highway, or other public right-of-way shall extend to the center of such vacation of all area included in the vacation shall they be subject to all regulations of the extended districts.
