Fiber roll installation details show straw wattle sediment rolls secured with three-quarter-inch by three-quarter-inch wood stakes at maximum four-foot spacing. Entrenchment details for slope areas require embedding the fiber roll twelve inches minimum into the soil with a maximum four-inch above-grade height, while flat areas rest on finished grade. Inlet protection details illustrate straw fiber rolls tightly wrapped around a drain grate with a sediment trap trench, including plan view and section views showing a two-point-five to one slope and a one-foot-wide by six-deep sediment trap trench around the drop inlet.
