Urbanized areas are associated with activities that contribute pollutants to stormwater runoff, such as application of anti/deicing compounds, vehicle fueling, spills, landscaping and lawn maintenance, and application of pesticides and fertilizers. Additionally, urbanized areas are characterized by large amounts of impervious surfaces, such as streets, driveways, roof tops, parking lots and sidewalks. Stormwater runoff from impervious surfaces travels faster and in larger quantities, which results in damage to rivers, streams and wetlands; destruction of aquatic habitats; and elevated pollutant levels reaching surface waters. Impervious surfaces also inhibit infiltration and subsequent groundwater recharge. Local public entities that own or operate a municipal separate storm sewer system (MS4) in urbanized areas play a key role in preventing or reducing the negative impacts stormwater runoff may have on Minnesota’s valuable water resources. Thus, the City of Rochester is required by law to manage stormwater runoff in order to restore and protect surface waters.
