All proposed plats submitted for Commission approval under the provisions of this chapter shall allocate adequate areas for streets. They shall be in conformity with the Comprehensive Plan and Thoroughfare Plan. They shall designate and label all such streets thereon according to the following definitions, specifications and requirements regarding platted width, right-of-way and control of access thereto.
(A) Expressway. Any street designated and labeled as an “expressway” shall be a divided arterial street designed, planned and intended for through vehicular traffic in conformance with the Comprehensive Plan and Thoroughfare Plan, with full and/or partial control of access thereto. Minimum width of right-of-way for an expressway shall be 120 feet where full control of access is contemplated or exercised. Minimum width shall be 165 feet where partial control of access is contemplated or exercised to permit access connections only at street intersections.
(B) Primary thoroughfare. Any street designated and labeled as a “primary thoroughfare” shall be an arterial street designed, planned and intended for through vehicular traffic in conformance with the Comprehensive Plan and Thoroughfare Plan with partial control of access thereto. As a general principle, primary thoroughfares shall be located at approximately one-mile intervals in a north-south, east-west grid pattern, except in congested areas where they may be located at more frequent intervals. Minimum width of right-of-way for primary thoroughfare shall be 90 feet. Partial control of access to a primary thoroughfare shall be exercised to permit access to each lot abutting thereon.
(C) Secondary thoroughfare. Any street designated and labeled as a “secondary thoroughfare” shall be designed, planned and intended to serve as a collector and distributor of through vehicular traffic. This shall be done in conformance with the Comprehensive Plan and Thoroughfare Plan from sections of land within the town to expressways, parkways and primary thoroughfares and vice versa, with partial control of access thereto. Minimum width of right-of-way for a secondary thoroughfare shall be 90 feet. Partial control of access to a primary thoroughfare shall be exercised to permit access to each lot abutting thereon. (Refer to “construction standards”.)
(D) Collector street. Any street designated and labeled as a “collector street” shall be designed, planned and intended to serve as a collector and distributor of vehicular traffic in conformance with the Comprehensive Plan. Collector streets shall carry vehicular traffic to and from expressways, parkways, primary thoroughfares and secondary thoroughfares, with partial control of access thereto. Such streets shall include, but not be limited to, entrance streets of residential subdivisions. Minimum width of right-of-way for a collector street shall be 70 feet. Partial control of access to collector streets shall be exercised to permit access to each lot abutting thereon. (Refer to “construction standards”.)
(E) Local street. Any street designated and labeled as a “local street” shall be designed, planned and intended to provide access to other streets from individual properties, in conformance with the Comprehensive Plan, primarily to provide access to lots abutting thereon, with partial control of access thereto. Minimum width of right-of-way for a local street shall be 50 feet in subdivisions designed for five dwelling units or less per acre of ground within the boundaries of the plat. Minimum width of right-of-way for a local street shall be 60 feet in subdivisions designed for more than five dwelling units per acre of ground within the boundaries of the plat or for commercial, industrial or other non-residential land uses. Partial control of access to local street shall be exercised to permit access to each lot abutting thereon. (Refer to “construction standards”.)
(F) Cul-de-sac. Any street designated and labeled as a “cul-de-sac” shall be designed, planned and constructed with one end open to vehicular traffic from an expressway, parkway, primary thoroughfare, secondary thoroughfare, collector street or local street. The closed end thereof shall be permanently terminated by a vehicular turnaround, in conformance with the Comprehensive Plan, with partial control of access thereto. Minimum width of right-of-way for a cul-de-sac shall be 90 feet in subdivisions designed for five dwelling units or less per acre of ground within the boundaries of the plat. Minimum width or right-of-way for a cul-de-sac shall be 110 feet in subdivisions designed for more than five dwelling units per acre of ground within the boundaries of the plat. Minimum width of right-of-way for a cul-de-sac in a commercial, industrial or other non-residential subdivision shall be 90 feet.
