Concentrated stormwater runoff means any stormwater runoff which flows through a drainage pipe, ditch, diversion or other discrete conveyance channel.
Sample 1Sample 2Sample 3
Concentrated stormwater runoff means surface runoff which converges and flows primarily through water conveyance features such as swales, gullies, waterways, channels or storm sewers and which exceeds the maximum specified flow rates of filters or perimeter controls intended to control sheet flow.
