Erosion is often the symptom and not the disease. Ongoing erosion (erosion in the same location) is often the symptom of a flaw in the watershed system surrounding the project area. This issue can often be reduced, and even eliminated, by adjusting the areas surrounding the aggregate surface. Divert water where possible using culverts, berms, and drains. If you do experience erosion damage, first look at ways to get the water away or slow the water down that’s causing the damage. Second, replace the lost aggregate with new blended aggregate material following the guidelines found in the Maintenance Page link below
