2023 Docket Enabling Ordinance December 19, 2023 <br />Page 94 <br /> <br /> <br />approach slope requirements shall be met to the maximum extent feasible. If it is <br />impossible to meet the requirement, the justification must be well documented and shall <br />be subject to approval by the County Engineer. <br />G. Corner Radii. At road intersections, the following typical minimum curb line radii for curb <br />returns shall be as follows: <br /> 1. Local Access Road-Local Access Road Intersection 25 feet <br />2. Local Access Road – Collector Intersection 30 feet <br />3. Collector-Collector Intersection 35 feet <br />4. Arterial-Arterial or Arterial-Collector Intersections 55 feet. <br />5. Private Roads 25 feet <br />Corner radii greater than the above ranges shall be used if the anticipated composition <br />of traffic warrants such a need. Curb radii shall be subject to approval by the County <br />Engineer. <br />H. The right-of-way or easement for roadways shall be rounded at intersections by an arc, <br />the minimum radius of which shall be no less than 35 feet. Additionally, corner lots shall <br />have no length dimension less than 90 feet. <br />I. When a new or reconstructed road is designed to intersect with another public road, an <br />intersection plan shall be submitted. The intersection plan must be clearly detailed to <br />show flow line grades and how surface drainage will be controlled at the intersection. <br />Curb return data shall be shown on the road construction plans. <br />J. At the intersection of roads with different classifications, the centerline slope and typical <br />cross section of the higher classified road should be carried through the intersection with <br />the lower classified road matching in a manner which will not interfere with the smooth <br />movement of traffic in the travel lanes of the higher classified road. <br />K. Where two roads of the same classification intersect, the centerline grade shall be <br />matched at the center of the intersection with cross slopes varying through the <br />intersection to allow drainage. All classes of local access roads shall be treated as the <br />same classification for purposes of this subsection.
