The boundaries of each zoning district are shown on a map entitled Official Zoning Map, Mauldin, South Carolina, which is hereby adopted and declared to be a part of this Ordinance.

2:1.1 Amendments.

Amendments to the Official Zoning Map shall be made as necessary so that the map at all times portrays the current status of the zoning districts or zoning district boundaries.

2:1.2 Custodian of Map.

Copies of the Official Zoning Map shall be kept on file in the office of the City Clerk and copies shall be available at all times for inspection by the public.

When uncertainty exists with respect to the boundaries of districts as shown on the Official Zoning Map, the following rules shall apply.

2:2.1 Delineation.

District boundary lines are intended to follow the center lines of streets, highways, alleys, easements, and other rights-of-way; the center lines of streams or other water channels; and platted lot or other property lines. In the absence of visual district boundaries or specified distances on the Official Zoning Map, dimensions or distances shall be determined by scaling the distance on the Official Zoning Map.

2:2.2 Interpretation.

When the physical or cultural features existing on the ground are at variance with those shown on the Official Zoning Map, the Board of Appeals shall interpret the district boundaries.

2:2.3 Divided Lot.

Where a district boundary divides a lot which was in single ownership at the time of passage of this Ordinance, the Board of Appeals may permit, as a special exception, the extension of the regulations for either portion of the lot not to exceed fifty (50) feet beyond the district line into the remaining portion of the lot.
