(A) Land Development and the associated increases in Impervious Cover can increase the quantity and nature of Pollutants carried by Stormwater runoff, increase Stormwater runoff rates and volumes, aggravate Stream Channel Erosion and Sediment transport, alter the hydrologic response of Watersheds, and degrade the ecological function of downstream Water Bodies.

(B) Stormwater Treatment Facilities and requirements can minimize those impacts by reducing Pollutant levels carried in Stormwater runoff, removing or reducing the concentrations of those Pollutants that are carried, reducing Stream bank Erosion, and by restoring Stormwater runoff rates and volumes to levels closer to the pre-Development hydrologic regimes.
