The following requirements shall apply to special street types:
(a) One Way Streets. One-way streets are permitted in new subdivisions if the Planning Commission determines that such streets are properly integrated with the existing and proposed street system in the area.
(b) Permanent dead-end streets shall not be permitted. Temporary dead-end streets shall be permitted only as a segment of a continuing street plan subject to extension into undeveloped acreage. Temporary dead-end streets shall extend to the boundary of such undeveloped acreage and shall be provided with an interim turnaround satisfactory to the City Engineer and Planning Commission in design. The Planning Commission shall reserve the right to limit the length of such a dead-end street based on principles of proper planning, and the Planning Commission may require a street along the boundary between a proposed subdivision and the undeveloped acreage to provide for future development.
(c) Cul-de-sac streets shall not exceed a length of one thousand (1,000) feet measured to the center of the radius of the turnaround. The terminus shall be circular with a minimum right-of-way radius of fifty (50) feet measured from a point on the street centerline.
(d) The dedication of new half-streets shall not be permitted. If a parcel to be subdivided exists adjacent to a dedicated or platted and recorded half-width street or alley, the other half-width of such street or alley falling within the proposed subdivision shall be platted, provided that in the opinion of the Planning Commission such right-of-way is necessary for the proper development of the area.
(e) Where a subdivision adjoins an arterial street, a marginal access street shall be designed to control access from lots fronting on it. Points of access to the arterial street shall be spaced at a minimum of thirteen hundred twenty (1320) feet. A planting strip having a minimum width of twenty (20) feet shall be provided between the pavement of the marginal access street. The minimum width of the marginal access right-of-way shall be fifty (50) feet. In addition, the Planning Commission may also require the provision of buffer planting strips, the platting of loop streets or cul de-sacs connected to such parallel streets, or any combination thereof.
(f) Easements or reserve strips controlling access to streets shall be prohibited except where deemed necessary by the Planning Commission and where their control is definitely placed with the County.
(g) In subdividing land along existing streets or roads and within a proposed subdivision, provisions for the dedication of land for one or more access streets to undeveloped land not fronting on an existing street or road shall be incorporated. Said access streets shall be spaced not less than eight hundred (800) feet, nor more than one thousand four hundred (1,400) feet apart.
(h) Alleys may be approved in residential subdivisions when justified by subdivision street design, to provide vehicular access to parking areas. Alleys may be approved in commercial and industrial subdivisions if no other provisions can be made for adequate service access. The minimum pavement widths for alleys shall be twenty (20) feet and they shall be dedicated to the public. Alley intersections, sharp changes in alignment, and dead-ends shall not be permitted.
