All proposed amendments, supplements, changes or modifications shall not become effective, except by a favorable vote by a majority of all the City Council members. If a proposed amendment is not acted upon finally by the City Council within 90 days after the conclusion of the public hearing by the City Council, such proposed amendment shall be deemed to have been defeated and denied, unless the applicant of such amendment shall have consented to an extension of such period of time. Whenever a proposed amendment is defeated, either by vote of the City Council or by reason of the operation of this section, such amendment shall not thereafter be passed without a further public hearing and notice thereof as provided in § 11-904 of this article.
