When the South Burlington City Offices property was constructed the site plan did not contain significant measures to manage stormwater runoff. As a result, runoff from this property flows untreated to Potash Brook. The property also has an expired State of Vermont stormwater permit. Future permit requirements will likely require installation of stormwater treatment practices.
The City worked with an engineer to create an improved plan for stormwater management on the City Offices property. The project included pipe and drainage structure replacement, construction of new drainage swales, construction of a bioretention area, and construction of a large underground infiltration area.
Stormwater runoff generated at the City Offices site is directed to one of the new stormwater treatment practices. The treatment system removes sediment and other pollutants before they leave the site. In addition, these stormwater treatment practices infiltrate excess volumes of stormwater runoff thereby recharging groundwater supplies. Infiltrating stormwater runoff reduces the volume of water reaching streams during a storm, prevents erosion of stream banks, and reduces the risk of downstream flooding.
