Performance Comparison of Surface and Underground Stormwater Infiltration Practices


The Kortright Centre parking lot showcases green building features and materials that make it more environmentally friendly than a typical one. As a demonstration of green parking design the original asphalt lot is being renovated to feature permeable pavements, rain gardens and infiltration trenches to manage rainwater and snowmelt in a cleaner, more natural way.

Initiated in 2013, this two year study evaluates the side-by-side performance of two common Low Impact Development stormwater management practices, bioretention cell and infiltration trench, subjected to the same local contexts and climate. This side-by-side design allows for the two practices to be compared with respect to their capacity to reduce runoff volumes and contaminant loads, as well as various functional attributes.
