US Patent 7029208 Biodegradable sediment barrier

The present application relates to systems and methods for making and using sediment barrier. More specifically the present application relates to systems and methods for using sediment barriers to reduce pollution of rivers and streams from sediment resulting from soil erosion at, for example, a construction site or other area of potential soil erosion. The sediment barrier typically includes at least one apron that serves to provide filtering, water velocity reduction and/or anchoring. The sediment barrier further includes a body portion that provides substantial filtering of sediment from water passing therethrough. The apron and/or body portions of the barrier are preferably composed of biodegradable material.
