Bare ground leaves with the first hard rain
Every cleared slope, pad and ditch sheds soil the first time it storms. Soil that leaves the site clogs culverts, muddies streams and ends up in a neighbor's yard, and it is the first thing regulators and neighbors notice.
Erosion control keeps the soil in place. Sediment control catches whatever moves anyway. You need both, because one without the other fails on the first big storm.
