(A) The width of major and secondary streets shall conform to the widths designated on the official maps relative to streets or to such widths as the City Planning Commission may determine to be necessary to carry out the intended function of the Trafficways Plan.
(B) The minimum width of streets whose ultimate length is in excess of 500 feet shall be 60 feet and shall not be less than 50 feet in any case. In cases where physical conditions appear to make the required minimum width of street impractical, the City Planning Commission may modify this requirement.
(C) Streets designed to have one end permanently closed (cul-de-sac) shall be not less than 50 feet in width and shall have a turning circle at the closed end with a radius of not less than 55 feet and a pavement width of not less than 22 feet. Such streets shall not extend for more than 450 feet from the centerline of the nearest intersecting street. Where conformance to this provision results in lots of greater depth than 150 feet at the end of such cul-de-sac, the maximum length of such streets may be increased to 500 feet. In cases where physical conditions make this maximum length of cul-de-sac impractical, the City Planning Commission may modify this requirement in any proposal for subdividing lands where a street cannot be extended in any practical manner to intersect the cul-de-sac within 450 feet of its terminus because of the existing adjacent development. The property line at the intersection of the turning circle and the straight portion of the street shall be rounded with a radius of not less than 20 feet.
(D) Where a subdivision abuts or contains an existing or proposed street or major trafficway, the City Planning Commission may require marginal access streets adjacent to such major trafficway where such lots front on such major street.
(E) Whenever a subdivision is adjacent to a railroad right-of-way, there shall be a street which is parallel to the railroad so as to restrict the number of grade crossings. The intersection of the centerline of the parallel street with that of any street that crosses the railroad shall not be less than 150 feet from the line of the railroad right-of-way.
(F) Access and right-of-way to all proposed streets across railroad rights-of-way, watercourses, or ditches shall be provided by the subdivider at his or her expense in a standard manner approved by the City Engineer.
