Before any ordinance, measure or regulations amending or changing the number, shape, area or regulations of/or within any zone or district may be passed, the Council shall hold a public hearing hereon. It shall post notice of such hearing in two (2) locations within the village for the entire thirty (30) days before the hearing, adequately describing the nature of the pending legislation. If the ordinance, measure or regulation intends to rezone, or redistrict fewer than ten (10) or more parcels of land, as listed on the tax duplicate, written notice of the hearing shall be sent by the Village Clerk, by first class mail at least twenty (20) days before the date of the public hearing, to the owners of property contiguous to and directly across the street from each parcel or parcels to the addresses of such owners appearing on the county Auditor’s current tax list or lists or the Treasurer’s mailing list and to such other list or lists that may be specified by Council. The failure of delivery of such notice shall not invalidate any such ordinance, measure or regulation. During such thirty (30) days the text of such ordinance, measure, regulations or proposed change, together with the map, or plans, or copies thereof forming part of or referred to in such ordinance, measure, regulation or proposed change, and the maps, plans and reports submitted by the Planning Commission shall be kept on file for public examination in the office of the Zoning Inspector or in such other office as may be designated by Council.
