Caltrans now requires the use of burlap wrapped straw wattles on many jobs. Since burlap is biodegradable, there is no clean-up required as opposed to the standard plastic netting. Why burlap wrapped (biodegradable) straw wattles? They can protect the environment for up to two years because the straw eventually mulches down and the plastic netting photodegrades. Since straw wattles have a low profile, they easily blend into the environment. They have been proven to keep our fresh water system free of pollution. Straw wattles are designed to stabilize slopes and prevent erosion by slowing the creep of loose soil and helping to break up the formation of rills and gullies. After decomposition, they become part of the landscaping. When left in place, they help prevent slope erosion. Each straw wattle contains natural straw. They capture sediment and spread water rather than concentrating the flow and volume, as drainage sewers do. Each fiber roll is nine inches in diameter and 25 feet long, weighing approximately 60 pounds. They are tubular and straw-filled, held together by photodegradable plastic or biodegradable burlap netting. Straw wattles are erosion, sediment, and storm water runoff control devices.
