The following requirements shall apply to special street types:
(a) Permanent dead-end streets shall not be permitted. Temporary dead-end streets shall be permitted for up to 24 months only as part of a continuing street plan, and only if a temporary turnaround satisfactory in design to the Commission is provided, and provisions for maintenance and removal are advanced. Temporary dead-end streets longer than 200 feet shall not be permitted.
(b) Dedication of new half-streets shall not be permitted. Where a dedicated or platted half-street exists adjacent to the tract being subdivided, the other half shall be platted.
(c) Where a subdivision adjoins an arterial street, a marginal access street shall be designed, if the subdivision design is such that residential lots would require direct vehicular access onto the arterial highway. Points of access to the arterial street shall be spaced at a minimum width of 1,320 feet. A planting strip having a minimum of 20 feet shall be provided between the pavement of the marginal access street and of the arterial street. The minimum width of the marginal access right-of-way shall be 50 feet.
(d) Alleys may be required in commercial and industrial districts if other provisions cannot be made for adequate service access. The minimum widths for alleys shall be 20 feet for the right-of-way and 18 feet for the pavement width.
