Section 6.16. Sight Lines. No fence, wall, hedge, or shrub planting which obstructs sight lines at elevations between two (2) and six (6) feet above the roadways shall be placed or permitted to remain on any corner Lot within the triangular area formed by the street property lines and a line connecting them at a point twenty-five (25) feet from the intersection of the street lines, or in the case of a rounded property corner, from the intersection of the street lines extended past the corner. The same sight line restrictions shall apply to any Lot within ten (10) feet from the intersection of a street property line with the edge of a driveway or alley pavement. No tree shall be permitted to remain within such distances of such intersections unless the foliage line is maintained at a sufficient height to avoid obstruction of such sight lines.
