Description: Various techniques to divert runoff from paved surfaces where a vegetated diversion is not feasible. The purpose is to direct stormwater runoff (sheet flow or concentrated) away from a direct discharge point and divert it to an approved BMP or naturally vegetated area capable of removing nutrients through detention, filtration, or infiltration. This may be accomplished through the use of the following: curb cuts, trench drains, raised concrete, or asphalt areas in parking lots, earthen berms, or check dams.
