The project is currently undergoing engineering design. Construction is anticipated for Fall 2022 / Spring May 2023. Work is currently scheduled to begin on August 29th, to include test pits to locate sewer services. The contractor will then be off-site until October, when the dry detention basin will be constructed. If weather permits, the storm drain will be constructed in the road this fall. Otherwise the storm drain will be constructed in the road next spring. This project will include a complete shut down of the bike path at the end of Lindenwood drive. We apologize for any inconvenience. 


The City of South Burlington Stormwater Utility received a grant from the Vermont Agency of Transportation to install a stormwater detention basin at the end of Lindenwood Drive. The project includes the design and construction of a stormwater detention basin within a City owned parcel and drainage infrastructure which would allow for the treatment of stormwater runoff form 2.2 acres of impervious surfaces.


Currently, untreated stormwater runoff generated from a 10.5 acre drainage area, including 2.2 acres of impervious surface from Lindenwood Drive and Brewer Parkway, discharges directly to the stormwater impaired Potash Brook at the end of Lindenwood Drive. This project was identified in the Potash Brook Flow Restoration Plan (FRP) and will help reduce peak flows in the stream that cause erosion and impairment of the stream. The project will also remove phosphorus (via the detention basin and a reduction of in-stream erosion), which benefits Lake Champlain.

Funding Sources

This project has received funding support from the Municipal Highway Stormwater Mitigation Program administered by VTrans. The grant is anticipated to pay for 80% of the deign and construction costs. The remaining project costs will be paid using stormwater utility capital project funding.
