A. Angle: Streets shall intersect at ninety degree (90°) angles or as close thereto as possible, and, in no case, shall streets intersect at less than seventy degrees (70°).
B. Number Of Streets Crossing At Intersection: No more than two (2) streets shall cross at any single intersection 1 .
C. Arterial Or Collector Streets: Intersections of arterial or collector streets shall be located on a relatively flat (2 percent or less) grade with appropriate drainage slope. The flat section shall extend a minimum of seventy five feet (75') measured from the edge of the street right of way, or beginning thirty feet (30') from the center of the intersection, whichever distance is greater.
D. Residential Streets Or Private Roads: Intersections of residential streets or private A, B or C roads or streets shall be located on a relatively flat (2 percent or less) grade with appropriate drainage slope. The flat section shall extend a minimum of fifty feet (50') measured from the edge of the street right of way, or beginning thirty feet (30') from the center of the intersection, whichever distance is greater.
E. Vertical Transition Curves: Vertical transition curves from roadway or street centerline grades to the flat approach sections of intersections shall be located outside the required, flat, approach sections.
F. Approach Gradients: Roads and streets shall approach all intersections at gradients of two percent (2%) or less. For each additional one percent (1%) of centerline road or street gradient, the flat approach section to the intersection shall be increased by an additional ten feet (10'); provided, that no such road or street centerline gradient shall exceed the maximum allowable gradient of the road or street according to table 2, section 7-6-7 of this chapter.
G. Clear Sight Distance: Minimum clear sight distance at all intersections shall permit vehicles to be mutually visible when each is a minimum of one hundred feet (100') from the center of the intersection.
H. Visibility Of Intersection: Intersections shall be clearly visible for a minimum of two hundred feet (200') from the center of the intersection from all roadways or streets. (Ord. 382, 10-25-2006)
