The location and widths of proposed streets shall be such as to reasonably fit in with any existing street development in adjoining allotments, so as to provide reasonable continuity of location and width, or with any plan of street development adopted by the Planning Commission or any other public authority. Where the land for a proposed allotment adjoins unallotted property capable of being allotted, the streets in such proposed allotment need only be carried to the boundaries thereof.
