Wherever any uncertainty exists as to the boundary of a zone as shown on the zoning maps, the following regulations shall control:
A. Where a boundary line is indicated as following a street or road, it shall be construed as following the centerline of such street or road.
B. Where a boundary line follows or approximately coincides with a lot or property ownership line, it shall be construed as following such line.
C. Where a boundary line is not indicated as following or approximately coinciding with a street, road, lot line or property ownership line, the boundary line shall be determined by the use of the scale designated on the zoning maps.
D. Where the boundary line of a zone divides a lot in single ownership, the boundary line shall be considered as the lot line for purposes of computing area and setback for uses that are permitted in the less restrictive zone. For uses that are permitted in the more restrictive zone, the ownership lines may be used in applying the area and setback requirements. (Ord. 86, 12-7-1993)
