Problem
The Laurel Hill South neighborhood was constructed before the State had requirements for stormwater treatment. As a result, all stormwater runoff generated within the development flows untreated, via a pipe drainage system, to Bartlett Brook. The original drainage network was constructed using corrugated metal pipe and had reached the end of its useful life. In addition, the pipe network was undersized and resulted in flooding of streets, backyards, and basements during large rain storms.
Description
The City worked with residents to replace the neighborhood’s existing drainage pipes with new pipes that are sized to meet current standards. In addition, a stormwater detention system was installed between Sebring Road and Sandalwood Road.
Benefit
The new stormwater drainage system is sized to improve conveyance of runoff and reduce the chances of neighborhood flooding. The stormwater detention system also provides benefits for the enivornment. This system detains water during large storm events so that flow at the discharge point is reduced. This will prevent streambank erosion in downstream Bartlett Brook.
Best Management Practices
Stormwater detention and pipe replacement.
Timeline
Construction was completed in 2016.
Total Project Value
$745,429
Funding Sources
The Lake Champlain Watershed Environmental Assistance Program managed by the U.S. Army Corp of Engineers and the South Burlington Stormwater Utility.
