On every corner lot within the triangle formed by the street lines of such lot and a line drawn between points on such lines which are 30 feet from the intersection thereof, there shall be no structure or planting of such nature and dimension as to obstruct lateral vision other than a post, column, or trunk of a tree (but no branches or foliage) which is of greater than one foot in cross-section or diameter. Such lateral vision shall be maintained between two horizontal planes, one of which is two and one-half feet, and the other which is 10 feet above the centerline grade of existing streets.
Since the purpose of this provision is to promote public safety by preserving reasonable sight distance for vehicular traffic at street intersections, the superintendent of public works may vary the specific requirements in those circumstances where structures of plantings between the two horizontal planes do not in fact interfere with sight distances.
