SECTION 4.13   PUBLIC HEARING ON ZONING ORDINANCE OR RESOLUTION.
   The President of Council shall set a date for a public hearing on each ordinance or resolution establishing, amending, revising, changing or repealing zoning classifications, districts, uses, or regulations, which hearing shall be after the thirty-day period provided in Sec. 4.12 within which the Planning Commission is required to return its written recommendations to the Clerk of Council. The Clerk of Council shall cause a notice of such public hearing to be published one time in a newspaper determined by the Council to be of circulation within the City at least fifteen days prior to the date of such public hearing, which notice shall contain the title of such ordinance or resolution and a brief description of any property to be zoned or rezoned. When such amendment, revision, change, or repeal involves 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 fifteen days before the date of the public hearing, to the owners of property within and contiguous to and directly across the street from such parcel or parcels to the addresses of such owners appearing on the County Auditor's current tax list or the Treasurer's mailing list and to such other lists as may be required by the Council. Such written notice shall contain the title of such ordinance or resolution and a brief description of any property to be zoned or rezoned. The failure of delivery of such notice shall not invalidate any such ordinance or resolution.
