The following shall be the minimum requirements for right-of-way of streets in any new subdivision within the city or within contiguous territory which is not more than one and one-half miles beyond the corporate limits of the city:
(A) The minimum widths of rights-of-way for streets shall be as follows:
(1) Collector streets, being those streets used primarily for through traffic, including those shown and designated on the official plan of the city as collector streets, shall have a minimum width of right-of-way of 64 feet.
(2) All other streets, including those designated and shown on the official plan of the city as local streets, shall have a minimum width of right-of-way of 52 feet.
(B) Whenever a street in a new subdivision is a continuation of an existing street in an adjoining subdivision, and the right-of-way of the existing street is less than the applicable width prescribed in (A) above, the right-of- way for the street in the new subdivision shall be as required in (A) above and a width transition for the proposed street pavement shall be provided.
(C) Whenever a street in a new subdivision is a permanent dead-end streetand is not and cannot be continued to another street, the street shall be provided with a permanent turn-around, the right-of-way for which shall be not less than 100 feet in diameter.
(D) In each instance in which the subdivider owns the land on both sides of a proposed street, the entire right-of-way for the street shall be dedicated by the subdivider.
(E) When a new subdivision adjoins a dedicated half street in an existing subdivision, the subdivider shall dedicate the remainder of the street.
(F) In those instances in which the owner or owners of a new subdivision own the land on only one side of an existing street, the right-of-way of which is narrower than that required by (A) above, the subdivider shall dedicate additional right-of-way of sufficient width to make that portion of the right-of-way lying between the centerline of the existing right-of-way and the outside edge of the additional right-of-way at least equal to one-half of the required right-of- way width.
(G) Collector streets may be designed with gradual curves having a radius of at least 500 feet except where a lesser radius is deemed safe and adequate to serve the public need. All other streets may be designed with gradual curves having a radius of at least 250 feet, except where a lesser radius is deemed safe and adequate to serve the public need.
(H) Cul-de-sacs should have a maximum length of 300 feet measured from the center line of the intersecting street to the center of the turnaround. However, cul-de-sacs which are furnished with an adequate crossing or exit at the extremities of the turnarounds, can have additional length so that such cul-de-sacs do not exceed a maximum length of 900 feet, measured from the center line of the intersecting street to the center of the turnaround. Such emergency crossing or exit must be connected with another thoroughfare and be adequate to support and allow passage of all emergency vehicles; and such crossings and exits shall be dedicated to the public use, with a width of at least 20 feet.
(I) Street intersection centerline offsets of more than one foot and less than 125 feet between adjacent intersections shall be prohibited.
(J) No private streets will be permitted.
