Council may, from time to time and on its own motion or on petition, after report by the Planning Commission (“the Commission”) and after hearing and public notice of such hearing given by one publication in the official newspaper at least 30 days before the time of hearing, amend, supplement or change the regulations and districts herein or subsequently established. Whenever the owners of all the property proposed to be changed shall present to Council a petition, duly signed and acknowledged by them, requesting any such amendment, supplement or change of the regulations prescribed for such district or part thereof, Council shall act upon such petition within ninety days after the filing thereof. In case, however, the proposed amendment, supplement or change is disapproved by the Commission or a protest against a change is presented, duly signed by the owners of twenty percent (20%) or more, either of the area of the lots included in such proposed change, or of those immediately adjacent in the rear thereof, extending 200 feet therefrom, or of those directly opposite thereto extending 200 feet from the street frontage of such opposite lots, the amendment shall not become effective except by a favorable vote of three-fourths of all members of Council.
