When uncertainty exists with respect to the location of boundaries of any zoning district as shown on the zoning map of the city, the following rules shall apply:

(1)

Unless otherwise specifically indicated, where district boundaries are indicated on the zoning map as approximately following the centerline of a street, highway, railroad, right-of-way line, stream bed or riverbed, or such centerline extended, then such centerlines shall be construed to be such boundaries.

(2)

Where district boundary lines are indicated on the zoning map as approximately following the corporate limits line of the city, then such corporate limits line shall be construed to be such district boundaries.

(3)

Where district boundaries are indicated on the zoning map as approximately following lot lines or such lot lines extended, then such lot lines or such lot lines extended shall be construed to be such district boundaries.

(4)

Where a district boundary divides a lot, the requirements for the district in which the greater portion of the lot lies shall be extended to the balance of the lot; provided, however, that such extension shall not include any part of such lot which lies more than 50 feet beyond the district boundary, and provided, further, that this provision shall not apply to a through lot. In the case of a through lot, the restrictions of the district applying to adjoining lots which front on the same street as the lot frontage in question shall apply.
