As the first suburban development in South Burlington, the historic Mayfair Park 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 Potash Brook. The original drainage pipe network was constructed on private property using corrugated metal pipe and was reaching the end of its useful life. Sediment buildup and corrosion of the drainage system, along with ongoing high groundwater problems, has resulted in flooding of basements in the
The City worked with neighborhood residents to move parts of the neighborhood’s drainage network into the City’s right-of-way by installing new perforated pipe and a Hydrodynamic swirl separator to provide treatment to stormwater runoff.
The new stormwater drainage system will allow for easier maintenance of the stormwater drainage system and reduce the chances of neighborhood flooding events. The new system will also contain a Hydrodynamic swirl separator that will remove sediment and other pollutants prior to discharge to Potash Brook.
