2024 Track 1 Day 2: Mouaket Patel


City of Toronto Crawford Lane LID Pilot


A few years ago, City of Toronto wanted to explore new technologies for mitigating flooding in the storm sewers during storm peaks. Two technologies were identified: Porous Interlocking Concrete Pavers (PICP) and Cupolex – a concrete arcade under the pavement where storm surface water could be stored.

In order to test the two technologies, City of Toronto joined hands with the suppliers and Toronto Metropolitan University to design, build, monitor surface water flow into the storm sewer, and evaluate performance of the sections being built. A laneway that has come up for rehabilitation was chosen.

Three sections were built: one section uses PICP, another section built with Cupolex and the third section was built using conventional design for comparison purposes.

Four and a half years later, City has received the monitoring report with promising results. The conceptual design of the experiment was presented in an earlier Latornell Conference and, at the time, the attendees requested us to report back on the monitoring results when we have them.
