(A) Refer to the town’s adopted Access Control Ordinance (Chapter 155) and adopted Street Standards. In the event of a conflict, the Planning Director may determine the most appropriate standard given the context of the subdivision. All dedicated and designated rights-of-way shall conform to the following minimum dimensions:
Street Right-of-Way | Minimum Dimensions |
Major arterial | See Thoroughfare Plan |
Minor arterial | See Thoroughfare Plan |
Collector | See Thoroughfare Plan |
Local (Appendix AB) | See Thoroughfare Plan |
Cul-de-sacs, when utilized | 50 feet in radius |
Utility easements | 15 feet |
(B) No more than two streets shall intersect at any one point unless specifically approved by the Commission. Generally, intersections of major streets should be at least 800 feet apart and any street jogs with centerline offsets of less than 150 feet should be avoided, as shown in Appendix L. Proposed new intersections along one side of an existing street shall, wherever practicable, coincide with any existing intersection on the opposite side of the street.
(C) Generally, streets shall intersect at 90 degrees whenever possible with a minimum distance of 100 feet; and shall generally not intersect at less than 80 degrees onto arterial or collector streets, as shown in Appendix M.
(D) To ensure adequate site distance, when the street centerline deflects more than 10 degrees, connections shall be made by horizontal curves. Generally, the minimum centerline radius for local residential streets shall be 150 feet and for all other streets shall be 400 feet, as shown in Appendix N.
(E) Generally, a tangent of at least 100 feet shall be introduced between reversed curves on local and collector streets, as shown in Appendix O.
(F) Proper sight visibility shall be maintained at all intersections.
(G) The maximum vertical grade for all streets shall not exceed 5%. The minimum vertical grade of all streets shall be 0.4%.
(H) When utilized, the maximum length cul-de-sac street shall be 1,300 feet measured along the center line from the intersection at origin through the center of the circle to the end of the right-of-way. The origin of a cul-de-sac shall be defined as the centerline of the first street intersected by the cul-de-sac. Each cul-de-sac shall have a terminus of nearly circular shape with a minimum right-of-way diameter of 100 feet.
