AASHTO MP 10-03 (2005)

This specification covers compost produced from various organic by-products for use as a surface mulch for erosion/sediment control on sloped areas. This technique may be used for both temporary and permanent erosion/sediment control applications.

This technique is appropriate for slopes up to a 2:1 grade (horizontal distance:vertical distance) and should only be used in areas that have sheet flow drainage patterns (not areas that receive concentrated flows). This technique may also be used on up to 1:1 slopes with proper consideration to length of slope and compost application rates (depth).
