1244.02   STREET CONSTRUCTION.
   (a)   The minimum width of any proposed street shall be sixty feet. At the intersection of streets, the rounding of corners is required, with minimum radii of twenty feet, unless otherwise permitted at angular intersections.
   (b)   Council, upon recommendation of the Planning Commission, may require wider streets than sixty feet, whenever, in its judgment, provision for public travel makes the wider streets desirable, or whenever any general plan for street development adopted by the Planning Commission requires, or Council requests, the establishment of streets of greater width.
   (c)   No so-called dead-end streets will be approved for dedication except where conditions make the extension of such streets impracticable. In such cases, a dead-end street may be approved, provided that adequate turning space for vehicles is placed at the dead-end.
   (d)   Turning space shall be of sufficient size to provide for a paved circular roadway at least twenty feet in width, the inside radius of which shall be at least 35 feet.
   (e)   Dead-end streets in developments shall be extended:
      (1)   Through the development to a point within 300 feet of its furthest extremity; or
      (2)   Where a topographical irregularity exists, to a point which shall be no less than 300 feet, measured from the center of the turn-around to the topographical irregularity.
   (f)   Intersecting streets shall be provided so that no block will be longer than 1,500 feet.
