Upon receipt of a petition or resolution of intention to amend the provisions of this chapter the Commission shall set a date for a public hearing thereon. Such date shall not be later than 45 days after the receipt of such petition or resolution unless CEQA needs to be considered.

Notice of the public hearing required by the provisions of Section 9-3.2402 of this article shall be given as required by law. Additional notice of the time and place of such hearing and the purpose thereof shall be given by posting at least three notices thereof not less than 10 days prior to such hearing along the streets upon which the property proposed to be affected abuts.

Each such notice shall consist of the words "Notice of Proposed Zoning Change" in letters not less than one inch in height and a statement in small letters setting forth a general description of the property proposed to be affected, the time and place of the public hearing thereon, and such other information as the Commission deems necessary.

At the conclusion of the public hearing required by the provisions of Section 9-3.2402 of this article, or continuations thereof, the Commission shall make a report of its findings and recommendations with respect to the proposed zoning amendment. The Commission report shall include a list of the persons who testified at the hearing, a summary of the facts adduced at the hearing, the findings of the Commission, and copies of any maps or other data and/or documentary evidence submitted in connection with the proposed zoning amendments. A copy of such report and recommendation shall be transmitted to the Council within 90 days after the first notice of such hearing; provided, however, such time may be extended with the consent of the Council or the petitioner for such amendment. In the event the Commission fails to report to the Council within such 90 day period of time or within the agreed extension of time, the zoning amendment shall be deemed approved by the Commission.

Upon the receipt of the recommendation of the Commission, or following the expiration of the 90 day period of time or agreed upon extension of time, the Council shall hold a public hearing on the petition or resolution of intention to amend the provisions of this chapter. Notice of such hearing shall be given as provided by law.
