No structure, wall, fence, shrubbery or tree shall be erected, maintained or planted on any lot which will obstruct the view of the driver of a vehicle approaching an intersection, except that shrubbery and low retaining walls not exceeding two and one-half feet in height above the curb level and shade trees where all branches are not less than eight feet above the street level will be permitted. For residential corner lots, this unobstructed area shall be a triangular section of land formed by the two street right-of-way lines and a line connecting them at points thirty feet from the intersection of said right of way, or, in the case of a rounded corner, the unobstructed area shall be construed to be the triangular area formed by the intersection of the street right-of-way lines extended and a line connecting them at points thirty feet from the intersection of said right-of-way lines (e.g. said area being a "football" shape with two arcs facing each other, connected at such curb line).
