Twin Oaks Stormwater Pond
Problem
When the Twin Oaks neighborhood was first built it included a central drainage channel that directed stormwater runoff to a detention pond. Within a year of construction, the berm around the original pond had failed and the drainage channel was beginning to erode. The system was no longer providing treatment of stormwater runoff.
Description
In 2009, residents of the Twin Oaks neighborhood worked with the South Burlington Stormwater Utility to upgrade their stormwater treatment system. The central channel was reconstructed and stone check dams were installed to prevent erosion. The detention pond was reconstructed so that it provides treatment of stormwater runoff and detention of increased volumes of runoff originating in the neighborhood.
Benefit
Sediment and other pollutants are removed from stormwater runoff leaving the Twin Oaks neighborhood. In addition, the stormwater runoff is detained and slowly released to prevent erosion of streambanks and reduce the risk of downstream flooding.
