Description
There are a series of seven stormwater ponds that manage runoff generated by Kennedy Drive. The City worked with an engineer to design improvements to these ponds, so that they can treat additional runoff.
Problem
Pond 5 previously managed a portion of Kennedy Drive impervious area and was originally designed to meet the WQv and overbank protection design standards. However, the pond was only designed to treat the additional impervious acreage associated with the Kennedy Drive road expansion and not maximized to treat the maximum drainage area feasible.
Kennedy Drive Pond 5 is known to have a high infiltration capacity due to sandy soils and is therefore capable of treating additional runoff. The City identified a project to expand the drainage area flowing to this system, including the runoff that originally went to Kennedy Drive Pond 6.
Benefit
This project was identified as part of the Potash Brook Flow Restoration Plan (FRP), prepared by the City of South Burlington, in an effort to reduce flows to the impaired Potash Brook and improve water quality in the Lake Champlain drainage area.
Funding
This project was funded by an agreement LC00A00394 awarded by the Environmental Protection Agency to the New England Interstate Water Pollution Control Commission in partnership with the Lake Champlain Basin Program. NEIWPCC manages LCBP’s personnel, contract, grant, and budget tasks and provides input on the program’s activities through a partnership with the LCBP Steering Committee.
Timeline
The project was constructed in the Fall of 2019.
