The Board of Commissioners may from time to time amend, supplement or repeal any of the regulations and provisions of this chapter. The procedure for the preparation of a proposed zoning ordinance as set forth in § 607 of the Pennsylvania Municipalities Planning Code, 53 P.S. § 10607, is hereby declared optional.

Before voting on the enactment of an amendment, the Board of Commissioners shall hold a public hearing thereon, pursuant to public notice. In addition, if the proposed amendment involves a zoning map change, notice of said public hearing shall be conspicuously posted by the Township at points deemed sufficient by the Township along the perimeter of the tract to notify potentially interested citizens. The affected tract or area shall be posted at least one week prior to the date of the hearing.

In the case of an amendment other than that prepared by the Planning Committee the Board of Commissioners shall submit each such amendment to the Planning Committee at least 30 days prior to the hearing on such proposed amendment to provide the Planning Committee an opportunity to submit recommendations.

If, after any public hearing held upon an amendment, the proposed amendment is changed substantially, or is revised to include land previously not affected by it, the Board of Commissioners shall hold another public hearing, pursuant to public notice, before proceeding to vote on the amendment.

At least 30 days prior to the public hearing on the amendment by the Board of Commissioners, the Township shall submit the proposed amendment to the County planning agency for recommendations.

Within 30 days after enactment, a copy of the amendment to this chapter shall be forwarded to the County Planning Agency.
