This technique is appropriate for slopes up to a 2:1 grade (horizontal distance:vertical distance) and on level surfaces and should only be used in areas that have sheet flow drainage patterns (not areas that receive concentrated flows).
The filter sock technology is appropriate for areas outlined above as well as areas of high sheet erosion, around inlets, and in other disturbed areas of construction sites requiring sediment control. Unlike filter berms, the filter sock technology may be used in areas that have concentrated flow drainage patterns, up to 10 gallons per minute per linear foot of filter sock.
