Wire backed silt fence
Wire backed silt fence should be used in high load or sensitive areas. The minimum wire size should be 14.5 gauge with a maximum opening of 6”x6”. Stake spacing should not exceed 6 feet on center. Wood stakes are preferred. The wire should be in contact with the ground but it is not necessary to bury the wire. The ground itself will provide lateral support without the buried wire.
