In case of disapproval the commission shall communicate its reasons to the council, and the council, by vote of not less than two-thirds of its entire membership, may overrule the disapproval and, upon the overruling, the council or the appropriate board or officer may proceed, except that if the public facility or utility is one the authorization or financing of which does not fall within the province of the council, then the submission to the planning commission shall be by the board having jurisdiction, and the planning commission's disapproval may be overruled by that board by a vote of not less than two-thirds of its entire membership. The acceptance, widening, removal, extension, relocation, narrowing, vacation, abandonment, change of use, acquisition of land for, sale or lease of any street or other public facility is subject to similar submission and approval, and the failure to approve may be similarly overruled.
