What happens to rain water along Stewart Street in Sandy Hill is being taken very seriously. The city has installed new rain gardens along the street, from Friel Street to King Edward Avenue, in an effort to improve water quality and reduce storm water runoff.
The greening involved extending the existing boulevards and installing rain gardens. Rain gardens are planted areas that improve water quality and reduce storm water runoff using a combination of soil, plants and mulch.
