(a) Front Yard. Solid walls, fences, hedges or screening materials which are sight obscuring may be built to a maximum of three (3) feet in height in any required front yard perimeter. Such walls, fences, hedges or screening materials may slope upward to connect with a higher side yard fence. The length of a sloped fence section shall not exceed one (1) section or a maximum of ten (10) feet. Walls, fences, hedges or screening materials which are not sight obscuring (at least fifty percent (50%) open) may be built to a maximum of six (6) feet in height in a front yard.
