Perimeter Controls, Pump and Sump

Using the asphalt berm and silt fence as the project perimeter-left is project, right is not- note that all sediment and water are contained within the project. Turbid water and sediment are directed to a sump and pump to be conveyed to an onsite stormwater treatment system (chitosan-enhanced sand filtration) before discharge to a local creek. There is no need to cover bare soil since the project is contained within the perimeter best management practices. Also, no vehicles can exit here so there is no possibility of sediment being tracked onto the highway.
