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 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 will be sized to improve conveyance of runoff and reduce the chances of neighborhood flooding. The stormwater detention system will also provide benefits for the enivornment. This system will detain water during large storm events so that flow at the discharge point is reduced. This will prevent streambank erosion in downstream Bartlett Brook.
