The following requirements shall apply to highway details on the preliminary plan:
(a) Plan.
(1) The plan of street improvements in the subdivision shall show the stations and angles to all intersecting streets and turn-arounds. All intersecting streets shall have a minimum curb radius of twenty-five feet. Where new streets intersect existing arterial streets, the edge of the pavement or the back of the curb shall have a minimum radius of thirty-five feet.
(2) Where a proposed street ends in a cul-de-sac, a tee or ball-shape turn-around will be acceptable. If a ball-shape turn-around is proposed, the minimum curb radius shall be forty-four feet.
(3) The limits of the proposed pavement shall be clearly indicated and all side streets shall be paved within the limits of the subdivision.
(b) Roadway Section. All concrete pavements shall have an overall minimum width of twenty-eight feet (back to back of curb) and a minimum thickness of eight inches. The concrete pavement shall be placed on a granular stone base of not less than four inches of thickness. The integral rolling curb shall have a depth of four inches. The entire right-of-way of all streets, including side streets, shall be graded the full width between property lines.
(c) Sidewalks and Handicapped Ramps. One-course four inch thick [six inches thick at driveways] concrete sidewalks shall be constructed on walkways, at intersections, on the long side of corner lots and along both sides of street connections, and at such other locations in the subdivision as approved by the Planning Commission, by and at the expense of the subdivision developer. Sidewalks shall be constructed in front of new buildings by the builder of the building. Handicapped ramps shall be constructed by the developer at each intersection, of a design that meets State Code requirements.
(d) Connections to Existing Pavements. Details of connections to existing pavements shall be shown with particular care as to elevation to maintain proper grade and proposed grades. Proposed grades shall be at the proper elevation to maintain grading with the existing pavement.
