2. Corresponds with a street shown on the official master plan or with a street on a subdivision plat approved by the commission or with a street on a street plat made by and adopted by the commission. However, the council may accept any street not shown on or not corresponding with a street on the official master plan or on an approved subdivision plat or an approved street plat, provided the ordinance or other measure accepting such street be first submitted to the city planning commission for its approval, and, if approved by the commission, be enacted or passed by not less than a majority of all the members of the council. If the ordinance or other measure accepting such street is disapproved by the commission, the ordinance or measure may be enacted or passed by not less than two-thirds of all the members of the council.
