What is Stormwater Management and why is it important?

Stormwater Mangement is the effort to reduce runoff of rainwater or melted snow into streets, lawns, and other sites and the improvement of water quality. In developed areas surfaces such as roofs, pavements, and roads prevent precipitation from naturally soaking into the ground. Instead water runs rapidly into the storm drains, sewer systems and drainage ditches, which can cause:

Flooding

Stream bank erosion

Increased turbidity (muddiness created by stirred up sediment) from erosion                                       

Habitat destruction

Combined storm sewer and sanitary system overflows

Infrastructure damage

This water also often carries debris, chemicals, bacteria, eroded soil and other pollutants to our creeks, streams, lakes, rivers, and wetlands. Detaining stormwater and removing pollutants is the primary purpose of stormwater management.
