The front lawn at Habitat for Humanity in Thunder Bay, Ont., is smaller thanks to the work of some volunteers, to build a new rain garden. The garden, measuring about four metres by three metres, will help absorb water running off of the roof of the group's office and ReStore in the city. The rain garden was created with the work of volunteers on Wednesday morning. "It's one of many different techniques that you can use in an urban watershed to manage storm water runoff," said Julia Prinselaar, a program coordinator with EcoSuperior.
