(A) The arrangement of streets in a subdivision shall either:
(1) Provide for the continuation or appropriate projection of existing principal streets in surrounding areas; or
(2) Conform to a plan for the neighborhood approved or adopted by the Planning Commission to meet a particular situation where topographical or other conditions make continuance or conformance to existing streets impracticable.
(B) Collector streets shall be so laid out that their use by through traffic will be discouraged.
(C) Street jogs with centerline offsets of less than 125 feet shall not be allowed.
(D) A tangent of at least 100 feet long shall be introduced between reverse curves on arterial and collector streets.
(E) When connecting street lines deflect from each other at any one point by more than ten degrees, they shall be connected by a curve with a radius adequate to ensure a sight distance of not less than 100 feet for minor and collector streets, and of such greater radii as the Planning Commission shall determine for special cases.
(F) Streets shall be laid out so as to intersect as nearly as possible at right angles, and no street shall intersect any other street at less than 75 degrees.
(G) Street right-of-way widths shall be not less than as follows or as otherwise approved by the Planning Commission.
Street Type | Right-of-Way |
Arterial | 80 feet |
Collector | 70 feet |
Minor | 60 feet |
(H) Half streets shall be prohibited, except where essential to the reasonable development of the subdivision in conformity with the other requirements of these regulations; and where the Planning Commission finds it will be practicable to require the dedication of the other half when the adjoining property is subdivided, the other half of the street shall be plated within such tract.
(I) Cul-de-sacs, designed to be so permanently, shall not be longer than 600 feet and shall be provided at the closed end with a turn-around having an outside roadway diameter of at least 90 feet, and a street property line diameter of at least 120 feet. Dead-end streets will not be accepted.
(J) No street names shall be used which will duplicate or be confused with the names of existing streets. Street names shall be subject to the approval of the Common Council.
(K) Street grades shall not exceed the following, with a variance allowable of a maximum of a 2% rise where strict application would render an unreasonable hardship.
Street Type | Percent |
Arterial | 6% |
Collector | 8% |
Minor | 10% |
(L) No street grade shall be less than 0.4%.
