(a) Arrangement. The arrangement, character, extent, width and location of all streets shall conform to the Comprehensive Development Plan. The design of proposed streets shall provide for both the continuation of existing streets and access to adjacent unplatted lands so that the entire area can be served with a coordinated street system.
(b) Street Classifications.
(1) Major arterial thoroughfares shall be planned for continuation of movement of fast traffic between points of heavy traffic generation and from one section of the community to another. They shall contain as few intersections with local streets as possible and shall minimize or prohibit direct access from adjacent properties. Such thoroughfares shall traverse the community and shall be spaced approximately one mile apart.
(2) Collector streets shall provide a traffic route from local streets to major arterial thoroughfares. These streets shall be spaced approximately one- fourth mile apart.
(3) Local streets shall provide direct and full access to each lot and shall be laid out so that their use by through traffic will be discouraged. The street system shall be so designed that all proposed streets shall be in general conformity with a plan for the most advantageous development of the entire neighborhood. The streets shall be extended to the boundaries of the tract to be recorded unless prevented by topography or other physical conditions or unless such extension is not necessary or desirable for the coordination of the layout of the subdivision with the development of adjacent tracts. Dead-end streets or cul-de-sacs shall be approved only when necessitated by topography or other physical conditions or where, in the opinion of the Planning Commission, they are appropriate for the type of development contemplated.
(4) Parallel streets may be required along an existing or proposed major arterial thoroughfare to provide access to lots along such thoroughfares.
(c) Street Right-of-Way Widths and Grades.
Minimum Grades Right-of-Way by Percent Classification Width in Feet Maximum Minimum Major arterial thoroughfare 80 5 * Collector, commercial and industrial streets 80 8 * Local streets Urban single-family 60 with curbs 8 * Urban multi-family 60 with curbs 8 * Light industrial 60 without curbs 8 * Parallel streets 40 with curbs 8 * |
*Minimum grade should be adequately constructed to accommodate proper drainage according to drainage system requirements as provided in Section 1111.04.
(d) Half Streets. Half streets shall be prohibited except where there is an existing half street adjacent to the subdivision in which case the remaining half of the street shall be platted.
(e) Cul-de-Sacs and Dead-End Streets. Streets designed to be a permanent cul-de-sac shall not be longer than 600 feet and shall be provided at the closed end with a turn-around having an outside pavement diameter of at least seventy-five feet and a street property line diameter of at least 100 feet. If such a street is of a temporary nature and a further extension into adjacent land is anticipated, then the turning circle beyond the normal street width shall be in the nature of an easement over the premises included in the turning circle, but beyond the boundaries of the street proper. Such easements shall be automatically vacated to abutting property owners when the dead-end street legally extends into adjacent land. If such dead-end street extends only one lot depth past a street intersection, no turn-around shall be required. The sub-divider shall be required to reserve to the Village a strip of land two feet in width at the end of all dead-end streets. This strip will become a dedicated highway only upon extension of a dedicated street. The developer will be required to rough grade all stub streets not required to be constructed.
(f) Corner Radii. Property lines at street intersections shall be rounded with a radius of not less than thirty feet for major arterial thoroughfares, collector and industrial streets, and twenty feet for local streets. Chords or cut-offs may be permitted in place of rounded corners.
(g) Horizontal and Vertical Curves. Angles in the alignment of street lines shall be connected by a curve with a radius on the center line of not less than 150 feet for local streets, 300 feet for collector and industrial streets and 500 feet for major arterial thoroughfares. Between reverse curves there shall be a tangent at least 100 feet long on major arterial thoroughfares. Every change in street grade shall be made with a vertical curve to provide sight distance suited to the location which in no case shall be less than 300 sight feet from a height of four and one-half feet.
(h) Intersections. Streets shall be laid out to intersect as nearly as possible at right angles and no street shall intersect any other street at an angle of less than sixty degrees. Multiple intersections involving junctions of more than two streets shall be prohibited.
(i) Street Jogs. Street jogs with center line offsets of less than 160 feet shall be prohibited. If deemed necessary by the Planning Commission, the minimum distance between center line offsets may be increased or adjusted.
