Projects - Rain Gardens Water Quality Project
Locations
Dorset Farms (red circle); Mayfair Park (yellow circle); Airport Parkway (blue
circle); Queen City Park (pink circle).
Problem
Runoff from single-family homes, driveways and lawns is a
pollution source.
Description
Rain gardens were installed on sites in four South
Burlington neighborhoods to demonstrate how this control
method can supplement traditional structural treatment
practices to reduce hydrologic impacts and sediment and
nutrient wash-off from typical single-family home
development in the Champlain Valley.
Benefit
By diverting roughly one-quarter of the stormwater runoff
from the impervious surfaces on each of the demonstration
sites through a rain garden, this project demonstrates how
homeowners can use landscaping to reduce their homes'
impacts on Lake Champlain. A major goal of this project is
to provide photo and monitoring documentation of the
benefits associated with diverting even a portion of the
stormwater runoff from single-family home sites, since on a
watershed-wide basis, these have a tremendous, although
un-concentrated, impact.
