Trees may be planted in sight visibility triangles provided that:
7.1 The trunk caliper, at maturity, does not exceed 12 inches in diameter;
7.2 The lowest branch of any tree is at least six feet above the
of the street or driveway, whichever is the determining factor in the sight visibility triangle; and
7.3 Trees are not planted in a line that could result in a solid wall effect when viewed at an angle.
