Fiber rolls (or straw wattles) are very effective for sediment control. They reduce the rate of water flow, simultaneously absorbing water and filtering sediment. When used for temporary sediment retention, fiber rolls can reduce off-site sedimentation by:

• Providing storm drain inlet protectionDirecting runoff water to retention and detention devicesReducing water velocities in areas of concentrated flow, such as waterways and swales, when installed as check structuresFunctioning as an alternative to silt fence for perimeter sediment control

Advantages to fiber rolls:

• Install more easily, particularly in shallow soils and rocky materialAre more adaptable to slope applications and contour installationsBlend in with the landscape and are less obtrusiveDo not obstruct hydraulic mulch and seed applicationsMay be removed or left in place following establishment of vegetation
