Location
Shelburne Road and Bartlett Bay Road, behind Shearer Chevrolet.
Problem
Uncontrolled stormwater runoff was causing erosion and high levels of phosphorous, nitrogen and bacteria pollution in Bartlett Brook, an impaired waterway.
Description
On a piece of un-buildable commercial land with a degraded stream in a culvert, a state-of-the-art stormwater treatment facility was built, transforming the land into a vegetated, restored stream corridor and constructed wetland that is keeping pollution out of Bartlett Brook and Lake Champlain. The Bartlett Brook Stormwater Treatment System demonstrates how a constructed wetland can be designed and sited for effective use in urban stormwater treatment situations.
Benefit
This project is showing excellent environmental results, with phosphorous, nitrogen and bacterial removal well above Vermont standards for stormwater systems. It also reduces flood hazards to a neighborhood downstream.
