Description
Straw wattles are erosion, sediment, and storm water runoff control devices. They are tubular and straw-filled, held together by biodegradable burlap netting. They capture sediment and spread water rather than concentrating the flow and volume, as drainage sewers do. Each straw wattle contains natural straw. When left in place, they help prevent slope erosion. After decomposition, they become part of the landscaping.
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. They have been proven to keep our fresh water system free of pollution. Since straw wattles have a low profile, they easily blend into the environment. They can protect the environment for up to two years because the straw eventually mulches down and the plastic netting photodegrades.
Since burlap is biodegradable, there is no clean-up required as opposed to the standard plastic netting. Caltrans now requires the use of burlap wrapped straw wattles on many jobs.
