What are Stormwater BMP (Best Management Practice) Facilities?
Stormwater BMP facilities are engineered facilities that are designed to convey storm runoff, remove pollutants and to control flow rates. These facilities include pipes, ditches, swales, filters, ponds, underground tanks and vaults. These systems are specifically designed to capture, treat, store and then slowly release stormwater runoff downstream or into the ground. • Why is Stormwater Runoff a Problem? As we cut woodlands, clear land, pave roads and parking lots, and construct houses and buildings, we change the permeability of the ground. Falling rain has fewer places to soak in gradually. Runoff on hard surfaces occurs faster and in greater volumes. Increased stormwater runoff can worsen flooding, erosion, and water pollution and destroy stream habitat. • What are the Benefits of Stormwater BMP Facilities? In addition to helping prevent flooding and erosion, Stormwater BMP facilities help to protect water quality by incorporating features that filter or remove sediments, excess n
