Abstract
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.

A biodegradable sediment barrier adapted to filter sediment from water that passes through the barrier, comprising:
- A. a body defining a longitudinal axis, an upstream surface facing an upstream direction, and a downstream surface facing a downstream direction, and comprising;
- i. a biodegradable fiber core;
- ii. a biodegradable body netting surrounding most of the fiber core, and
- B. an apron connected to the body that:
- i. comprises a biodegradable apron netting,
- ii. extends in at least the upstream direction to define an upstream apron portion, and
- iii. is attached to the body at a plurality of attachment points that define a first path
- along the body and a second path along the body that is spaced apart from the first path, and
- in which the first path and the second path are substantially parallel to the longitudinal axis.
A method of making a biodegradable sediment barrier, comprising the steps of:
- A. bundling a plurality of biodegradable fibers into a cylindrical body that defines a longitudinal direction;
- B. attaching a first edge of a biodegradable netting to the body along a first path that extends in the longitudinal direction on the surface of the body;
- C. wrapping the netting around the cylindrical body so that a first attachment portion of the netting spaced apart from the first edge contacts the first edge;
- D. attaching the first attachment portion to the body along the first path;
- E. attaching a second attachment portion of the netting that is located farther away from the first edge than the first attachment portion to the body along a second path that is spaced apart from the first path.
