(a) Dead-end public streets shall be prohibited except as temporary stubs to permit future street extension into adjoining tracts, or when designed as permanent cul-de- sacs.
(b) Any dead-end street which is constructed for future access to an adjoining property, or because of authorized staged development, and which is open to traffic, shall not exceed five hundred (500) feet in length and shall be provided with a temporary, all-weather turnaround. The turnaround shall be completely within the boundaries of the subdivision and the use of such turnaround shall be guaranteed to the public until such time as the street is extended.
(c) Streets planned to be permanently closed at one end shall not exceed five hundred (500) feet in length as measured between the centerline of the turnaround at the closed end and the centerline of the intersecting street at the other end, and shall terminate at the closed end in a permanent circular cul-de-sac. Cul-de-sacs shall have a right-of-way diameter of at least one hundred (100) feet and a paved cartway diameter of at least eighty (80) feet. Such cul-de-sacs shall be constructed in the same manner as the street cartway and shall meet all applicable provisions of these Regulations.
