Twin Oaks Stormwater Pond


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.

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 detains stormwater runoff originating in the neighborhood.

Central drainage channel regraded
During reconstruction, the central drainage channel was regraded. Stone check dams were added to reduce erosion in the channel.


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 stream banks and reduce the risk of downstream flooding.
