§ 74-98. Vision clearance triangles.

(a)

A vision clearance triangle is a triangular area at the intersection of two streets, a street and an alley or a street and a railroad, two sides of which are curb lines or edge of pavement lines measured from the corner intersection of the curb lines or edge of pavement lines to a distance specified in this chapter. The third side of a triangle is a line across the corner joining the ends of the two sides. Where the curb lines or edge of pavement lines at an intersection have rounded corners, the lines will be extended in a straight line to a point of intersection.

(b)

The vision clearance areas shall contain no plantings, walls, structures or temporary or permanent obstructions exceeding 3½ feet in height measured from the top of the curb. Where trees exist they shall be kept trimmed seven feet high from the lowest branches to the top of the curb to permit adequate visibility of traffic signs and signals, and oncoming traffic. Any existing condition shall be maintained in such a manner that it will not block the view of oncoming traffic or create a traffic hazard.

(c)

Vision clearance areas shall be a minimum distance of 50 feet at street intersections or 25 feet at intersections involving an alley as represented in the following diagram:
