Low Impact Development (LID)
Low Impact Development (LID) is an innovative stormwater management approach that treats, infiltrates, filters and retains runoff at the source. LID is rapidly becoming the new norm in Ontario.
Why do we need LID in our watershed?
Urbanization and traditional development practices bring with them more hard or impervious surfaces that water cannot soak through, such as rooftops, parking lots, roads and driveways. This increase in hard surfaces changes the flow of water from urban lands during storms and snow melt events. The result is more water running off land faster and more frequently, causing erosion and increasing the risk of flooding. As well, when water flows down city streets, it picks up chemicals, trash and bacteria, and carries those pollutants into the storm drain system, where they are carried directly out to our creeks, the Thames River and, eventually, to Lake Erie.
