The following requirements shall apply to special types of streets.
(A) Cul-de-sac streets. Cul-de-sac streets shall not exceed 200 feet in length. The closed end shall be a paved turnaround having a minimum radius of 40 feet to the outward pavement edge, and a radius of 50 feet to the right-of-way line. The minimum frontage or lot width shall be measured at the required building setback line on any cul-de-sac.
(B) Dead-end streets. Permanent dead-end streets shall not be permitted. Temporary dead-end streets shall be permitted only as part of a continuing street plan, and only if a temporary turn-around satisfactory to the Commission in design, maintenance and removal is provided, and the temporary street has a surfaced turning area equal in diameter to two times the width of said street at its termination. Dead-end streets longer than 200 feet shall be permitted only after approval by the Commission.
(C) Dedication of half-streets. Dedication of half-streets shall not be permitted. Where a dedicated half-street exists adjacent to the tract being subdivided, both halves shall be platted.
(D) Access streets. Where a subdivision adjoins a major thoroughfare, a marginal access street shall be designed to control access to the thoroughfare from lots fronting on it. Access is controlled in the interest of public safety and to maintain the design capacity of the street system. Points of access to the thoroughfare shall be spaced at a minimum interval of 1,320 feet. A planting strip having a minimum width of 20 feet shall be provided between the pavement of the thoroughfare and the pavement of the marginal access street. The minimum width of the marginal access right-of-way shall be 28 feet.
(E) State highways. Before any subdivision plat is approved affecting any land within 300 feet of the centerline of a proposed new highway or a highway for which changes are proposed, as described in the certification to local officials by the State Transportation Director, or any land within a radius of 500 feet from the point of intersection of said centerline with any public road or highway, the Planning Commission shall give notice, by registered or certified mail, to the Transportation Director. The Planning Commission shall not give final approval of the subdivision plat for 120 days from the date the notice is received by the Transportation Director. If the Transportation Director notifies the Planning Commission that he or she shall proceed to acquire the land needed, then the Planning Commission shall refuse to approve the subdivision plat. If the Transportation Director notifies the Planning Commission that acquisition at this time is not in the public interest or upon the expiration of the 120-day period or any extension thereof agreed upon by the Highway Director and the property owner, the Planning Commission may if the application is in conformance with all provisions of this regulation, approve the subdivision plat.
