TxDOT note: Silt fence posts must be driven minimum 12" into the ground. Fabric must be trenched in 6" at the base. Wire-backed (pre-assembled) fence is required when flow concentrations exceed standard ratings.
Calculate gabion basket quantity and rock fill volume for walls, bank armoring, or slope protection. Standard basket: 3 ft × 3 ft × 1 ft.
