If the proposed amendment intends to rezone or redistrict ten or less parcels of land, as listed on the tax duplicate, written notice of the hearing shall be mailed by the Clerk of Council, by first class mail, at least ten (10) days before the day of the public hearing to all owners of property within, contiguous to and directly across the street from the area proposed to be rezoned or redistricted to the address of the owners appearing on the County Auditor's current tax list or the Treasurer's mailing list and to such other list or lists that may be specified by Council. If the proposed amendment intends to rezone or redistrict more than ten parcels of land, notice of the hearing shall be provided only by newspaper as indicated in Section 1113.10.
