Bartlett Bay Stormwater Treatment System Expansion

Location

Shelburne Road and Bartlett Bay Road, behind Shearer Chevrolet.

Planting the Bartlett Bay Stormwater Treatment System During Initial Construction

Description

The City of South Burlington Stormwater Utility received a grant from the Vermont Agency of Transportation (VTrans) to expand an existing stormwater pond in order to provide treatment to an expanded drainage area. The project includes the design and construction of the expansion of the Bartlett Bay Stormwater Treatment System (BBSTS) and drainage infrastructure which would allow for the treatment of stormwater runoff form an additional 9.34 acres of impervious surfaces.

Problem

Currently untreated stormwater runoff generated from a 9.34 acres  of impervious surface, discharges directly to the impaired Bartlett Brook near the intersection of Harbor View Road and Shelburne Road. This project was identified as part of the Bartlett Brook Flow Restoration Plan (FRP), prepared by the City of South Burlington, in an effort to reduce flows to the impaired Bartlett Brook and improve water quality in the Lake Champlain drainage area.

Benefit

This expansion project can provide Water Quality and Channel Protection treatment for an additional 9.34 acres of impervious surfaces that currently discharge untreated to Bartlett Brook. This type of expansion project has the added benefit of a minimal amount of additional maintenance for a significant increase in stormwater treatment.
