The City of South Burlington retained Hoyle Tanner to evaluate the seven existing Kennedy Drive ponds and adjacent drainage areas to identify which pond retrofit and rerouting opportunities should be advanced to engineering design.
The City is a regulated Municipal Separate Storm Sewer System (MS4) Operator with the majority of impervious surfaces (85%) in the Potash Brook watershed. Kennedy Drive is a major roadway located within the Potash Brook watershed that connects I-189 to US Route 2 (Williston Road) and was reconstructed in 2007 by VTrans. As part of the Kennedy Drive reconstruction project, a series of seven stormwater treatment ponds were constructed to treat runoff from the upgraded roadway and some adjacent areas.
Concepts to enlarge the existing drainage area, direct new runoff to the existing treatment practices, expand and/or modify existing ponds were developed for each of the seven ponds. This successful study has led to the design and construction of ponds #3 and #5/6, with pond #2 currently under design by Hoyle Tanner with VTrans MA funding assistance.
