(a) Ordinances or resolutions establishing, amending, revising, changing, or repealing zoning classifications, districts, uses, or regulations shall be initiated by a member of Council. Immediately after the first reading of the ordinance or resolution, the Presiding Officer of Council shall set a date for a public hearing before a joint meeting of Council and the Planning Commission, but not earlier than 13 days after the first reading. The Clerk of Council shall cause a notice of the public hearing to be published once in a newspaper of general circulation within the municipality at least seven days prior to the date of the public hearing. When the 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 certified mail with return receipt at least seven days before the date of the public hearing to the owners of the property within, contiguous to, and directly across the street from the affected parcel or parcels. Such notices shall be sent to the addresses of owners appearing on the County Auditor's current tax list and to other lists as may be required by Council. The failure of delivery of the notice shall not invalidate any ordinance or resolution.
(b) Immediately after the public hearing referred to in subsection (a) hereof, a copy of each ordinance or resolution establishing, amending, revising, changing, or repealing zoning classifications, districts, uses, or regulation shall be referred to the Planning commission. Within 15 days after receipt of referral, the planning Commission shall return to the Clerk of Council the written recommendations of a majority of the members of the Commission. The ordinance or resolution shall be given its second reading at the next regular meeting of Council, unless an earlier special meeting is called for that purpose.
(c) A concurring vote of at least two-thirds of the membership of Council shall be necessary to pass any zoning ordinance or resolution which differs from the written recommendations of the Planning Commission, but in no event shall an ordinance or resolution be considered as having passed unless it receives at least a majority vote of the members of Council.
