In order that proposed streets may be as nearly co-terminous as possible with existing streets in adjoining allotments, due provision shall be made for the direct continuation of all existing streets which extend to the boundaries of a proposed allotment. In case of adjacent allotments separated by existing thoroughfares, due provision shall be made for continuing in a practical manner such of the existing streets through the proposed allotment as may be necessary for public requirements, subject to the approval of Council.
