[1969 Code § 88-11; Ord. No. 1978-6]
In all districts where front yards are required on corner lots, all walls, fences, ornamental structures, hedges, shrubbery or other plantings, other fixtures and structures, and ground elevation located within a triangular area having two twenty-five-foot sides measured along the front lot line and side street line from the intersection point of such lines shall be limited in height so as to prevent the impairment of vision at street intersections. Such height shall not be in excess of three feet above the established curb elevation of the nearest curb, except that retaining walls shall be permitted where changes in street grade, width, or alignment have made such structures necessary. In the case of trees within this triangular area, all branches shall be trimmed away to a height of nine feet above the curb level, where vision is measurably impaired or obstructed.
