§ 152.35 STREETS.
   (A)   Streets shall conform to all minimum requirements of the general specifications and typical cross-section as set forth. When a tract to be subdivided embraces any part of a proposed street, such part of the proposed public bay shall be platted by the subdivider in the location and width proposed.
   (B)   (1)   The proposed subdivision shall conform to the various elements of the master plan and shall be considered in relation to the existing and planned major thoroughfares and collector streets, and such part shall be platted in the location and the width indicated on such plan.
      (2)   The street layout shall include minor streets so laid out that their use by through traffic shall be discouraged.
      (3)   For a proposed major thoroughfare, the Commission may require marginal access streets, reverse frontage, or such other treatment as may be necessary for adequate protection of residential properties and to afford separation and reduction of traffic hazards.
      (4)   Should a proposed subdivision border on or contain a railroad, expressway, or other limited access highway right-of-way, the Commission may require the location of a street approximately parallel to and on each side of a right-of-way at a distance suitable for the development of an appropriate use of the intervening land such as for parks in residential district. The distances shall be determined with due consideration of the minimum distances required for approach grades to future grade separation.
   (C)   Street right-of-way widths shall conform to at least the following minimum requirements:
   Street Type   Right-of-Way Widths
   Local streets   60 feet
   Marginal access streets   50 feet
   Turn-around (loop) streets   110 feet diameter
   Cul-de-sac streets — turn around   100 feet diameter
   (D)   Maximum length for residential cul-de-sac streets shall generally be 600 feet. Maximum length for industrial and other cul-de-sac streets may exceed 600 feet by approval of the Commission.
   (E)   For adequate drainage, the minimum street grade shall not be less than 0.5%. The maximum street grade shall be 6%.
   (F)   Minimum radii of curvature on the center lines, where a deflection in the alignment of a street occurs, a curve shall be introduced, provided for:
      (1)   Major streets of 100 feet.
      (2)   Other streets, a minimum radius of 100 feet, should be much greater wherever possible.
   (G)   Tangents between reverse curves there shall not be less than a minimum tangent for:
      (1)   Major streets of 100 feet.
      (2)   Other streets of 50 feet.
   (H)   (1)   At street intersections, property line corners and also street pavement shall be grounded by an arc at least 20 feet in radius.
      (2)   No street shall intersect a major street at an angle of less than 70 degrees.
