Fences shall be so located and of sufficient height to completely screen the junk yard from ordinary view from any highway within the prescribed distances. Although the minimum height of any fence is stated to be six feet, it must be emphasized that height must be sufficient to accomplish the complete screening from ordinary view. All fences shall be well constructed and maintained. Only sound undamaged material, uniform in appearance, and erected in a workmanlike manner will be acceptable.
