Urbanization that takes place in any growing city can increase the amount of runoff during heavy rains and reduce downstream water quality. Minimizing these impacts requires careful storm water management.
The EPA now considers stormwater pollution to be one of the most significant sources of contamination in our nation's waters. Stormwater from developed areas erodes stream banks and smothers stream beds with sediment.
Accumulated chemicals and bacteria flush off the land and into streams. Poor stormwater management can destroy stream life, pollute drinking water, increase flooding, and damage property.
