As more land is developed in the watershed, the amount of impermeable surface increases.   This creates more runoff that enters Huron Creek through surface channels and drains, carrying sand and soil with it.  In addition, the water that flows over roads and parking lots picks up contaminants.   These contaminants include salts, oils, antifreeze, and small amounts of metals such as zinc.  On well designed sites, there are detention or retention ponds that slow the flow of water and reduce the concentration of sand and contaminants.  Managing storm water is an important part of any watershed managment plan.
