When uncertainty exists with respect to the boundaries of the various districts as shown on the zoning map, the following rules shall apply:
A. District boundary lines are either the centerline of railroads, highways, streets, alleys or easements, or the boundary lines of sections, quarter sections, divisions of sections, tracts of lots of such lines extended otherwise as indicated.
B. In areas not subdivided into lots and blocks, wherever a district is indicated as a strip adjacent to and paralleling a street or highway, the depth of such strips shall be in accordance with the dimensions shown on the maps measured at right angles from the centerlines of the street or highway, and the length of frontage shall be in accordance with dimensions shown on the map from sections, quarter section or division lines, or centerlines of streets, highways or railroad rights of way unless otherwise indicated.
C. Where a lot held in one ownership and of record on the effective date hereof is divided by a district boundary line, the entire lot shall be construed to be within the more restricted district. (Ord. 2010-04-07, 4-1-2010)
