The management of stormwater runoff is at once a simple concept and a complex problem. Precipitation runs off impervious surfaces rather than infiltrating into the soil. The cumulative impact resulting from the increased frequency, volume, and flow rate of stormwater runoff can lead to destabilization of downstream channels and can also result in increased pollutant loading to waterways.
The Stormwater Management Program provides regulatory oversight and technical assistance to ensure proper design and construction of stormwater treatment and control practices as well as construction-related erosion prevention and sediment control practices, necessary to minimize the adverse impacts of stormwater runoff to surface waters throughout Vermont.
