“Treat soil as a resource not a pollutant,” said Mike Harding of Geosyntec Consultants. It takes 10,000 years for nature to make an inch of topsoil. Harding explained, “Vegetation is the skin of the earth, and when vegetation is removed, the earth bleeds. That’s what we call erosion.” Behind population growth, the World Bank has recognized that conserving topsoil is the second biggest global challenge.
Harding urged anyone disturbing soils to:
- Control water, beginning at the top of the slope
- Prevent erosion by limiting the amount of area disturbed
- Minimize erosion on all slopes
- Do more than just install silt fence at slope bottoms
Silt fences and other sediment control devices do not prevent erosion. When property installed and maintained, they contain runoff and sedimentation before it can move offsite or pollute waterways.
