No amendment, change, supplement, modification or repeal of this chapter shall become effective unless the ordinance proposing same shall first have been referred to the Planning Board for approval, disapproval or suggestions. The Planning Board shall make and transmit to the Borough Council, within thirty-five (35) days of referral, a report, including recommendations concerning the proposed amendment, change, supplement, modification or repeal. The Borough Council shall review the report, including recommendations concerning the proposed amendment, change, supplement, modification or repeal, and may disapprove or change any recommendation only by a vote of a majority of its full authorized membership and shall record in its minutes the reasons for not following such recommendations. Failure of the Planning Board to transmit its report within the thirty-five-day period provided herein shall relieve the Borough Council from the requirements of this section.
