A. Angle of intersection. Street shall be laid out to intersect at right angles and may be curved, if necessary, in order to make this possible. In no event shall a street intersect any other street at any angle of less than seventy-five (75) degrees.
B. Radius of residential streets. Street corners on local residential streets shall have a minimum radius of twenty (20) feet at the curb line or its equivalent.
C. Radius of commercial and industrial streets. Street corners on commercial and industrial streets shall have a minimum radius of twenty-five (25) feet at the curb line or its equivalent.
D. Radius of major streets. Street intersections involving major streets shall have a minimum street corner radius of thirty (30) feet at the curb line or its equivalent.
E. Area of clear vision. A twenty-five (25) foot area of clear vision at street intersections in subdivisions shall be provided. This area shall be kept clear of all structures and vegetation exceeding a height of three (3) feet above the established municipal street elevation. Where any street intersection will involve earth banks or existing vegetation inside any lot corner that would create a traffic hazard by limiting visibility, the developer shall cut such ground or vegetation, including trees, in connection with the grading of the public right-of-way to the extent deemed necessary to provide an adequate sight distance.
F. Grade. Intersections shall be designed with a flat grade wherever practical. In hilly or rolling areas, at the approach to an intersection, a leveling area shall be provided having not greater than a two percent (2%) rate at a distance of sixty (60) feet, measured from the nearest right-of-way line of the intersecting street.
