About Stormwater Management
Stormwater management is important for maintaining clean water and preserving streams, rivers, and lakes. The City of Kalispell's Storm Water Management Ordinance 1600 went into effect May 2, 2007, as mandated under the Federal Clean Water Act (CWA) and the Montana Pollution Discharge Elimination (MPDES) regulation. These regulations are designed to protect water quality in water bodies by reducing pollutants in stormwater that is carried into the storm conveyance systems and then into streams, rivers, and lakes.
Often construction begins with removal of vegetation and grading of the site. The lack of ground cover makes these sites especially vulnerable to soil erosion. Sediment-laden water can be washed off-site and into lakes and streams. The sediment reduces the amount of sunlight reaching aquatic plants and smothers bottom dwelling-insects and fish.
