Laurel Hill South Stormwater Project

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 pipe network was constructed using corrugated metal pipe and is reaching the end of its useful life. In addition, the pipe network is undersized and results in flooding of streets, backyards, and basements during large rain storms.

Description

The City is working with neighborhood residents to improve the neighborhood’s drainage network and install stormwater detention and treatment.

Benefit

The new stormwater drainage system will be sized to improve conveyance of runoff and reduce the chances of neighborhood flooding events. The new system will also contain stormwater detention and treatment practices that will remove pollutants from stormwater runoff and detain excess volumes of water to prevent erosion of streambanks downstream of the neighborhood.

Best Management Practices

Stormwater detention and pipe replacement.

Timeline

Project evaluation and engineering work began in 2010. Construction is scheduled for Spring 2016.

Funding Sources

The Lake Champlain Watershed Environmental Assistance Program managed by the U.S. Army Corp of Engineers and the South Burlington Stormwater Utility.
