Business Case for Permeable Pavement in Cold Climates: “Insurance doesn’t cover overland flooding,” says University of Toronto Professor Jennifer Drake


Function and Benefits of Permeable Interlocking Concrete Pavement

At a recent Construct Canada seminar held in Toronto, a university professor (Jennifer Drake) and an industry association representative (Robert Bowers) made the environmental and business case for the greater use of permeable pavement.

“Our drainage infrastructure is undersized to provide the desired level of safety for our communities,” said Jennifer Drake.

Then there are the safety and public damage risks. “Insurance doesn’t cover overland flooding which means they (homeowners) can’t get coverage,” said Drake, noting that while disaster relief funds can be made available, ultimately that relief “is paid for by the taxpayer.”

Her comments were a lead into an overview of the function and benefits of permeable interlocking concrete pavement.

Her research interests are directed towards Low Impact Development (LID) stormwater systems, watershed planning and stormwater management, and the impact of LID technologies on aquatic environments, urban water security and wet weather policy.  She is Co-Researcher, Hydrology at the Green Roof Innovation Testing Laboratory in the John H. Daniels Faculty of Architecture, Landscape, and Design.

Robert-Bowers_trimmed_120pPICP, which is the acronym for permeable interlocking concrete pavement “cleans, detains and reduces the amount of stormwater which has to be handled by infrastructure systems,” said Robert Bowers, Director of Engineering for the Interlocking Concrete Pavement Institute.

In projects where it’s in place, the stormwater drainage infrastructure can be much smaller and less land is required to accommodate that infrastructure, he added.
