Improving stormwater in urban and rural areas helps to protect the health of rivers, streams and lakes. Improvements made to an existing building or parking lot are known as a retrofit. The Ecology Action Centre is currently considering sites within the city of Halifax for a potential stormwater retrofit project. Learning from retrofit projects in other cities is helpful for developping options for a site in Halifax.
The short video below demonstrates two types of retrofits: a bioretention pond that captures and treats runoff from a large parking lot and rainwater harvested off a roof that is used for irrigating a sportsfield.
