Before voting on the enactment of an amendment, the governing body shall hold a public hearing thereon, pursuant to public notice. In the case of an amendment other than that prepared by the Planning Commission, the governing body shall submit each such amendment to the Planning Commission at least 30 days prior to the hearing on such proposed amendment to provide the Planning Commission an opportunity to submit recommendations. If, after any public hearing held upon an amendment, the proposed amendment is revised, or further revised, to include land previously not affected by it, the governing body shall hold another public hearing, pursuant to public notice, before proceeding to vote on the amendment. Where a County Planning Commission exists, amendments shall be submitted 30 days prior to the scheduled public hearing.

Public notices of the proposed amendment shall include either the full text thereof or a brief summary setting forth with the principal provisions in reasonable detail and a reference to a place within the municipality where copies of the proposed amendment may be examined, in addition to the time and place of hearing.

After enactment, the advertisement of the amendment may consist solely of a reference to the place or places within the municipality where copies of such amendment shall be obtainable for a charge not greater than the cost thereof and available for examination without charge. The amendment may be incorporated into the Official Ordinance Book by reference with the same force and effect as if duly recorded therein.
