Keynote Speech Abstract

THE CITY OF TORONTO’S CLIMATE CHANGE ADAPTATION STRATEGY TO MITIGATE URBAN FLOODING

Toronto, Canada’s largest city, is home to a diverse population of 2.8 million people living and working along the shores of Lake Ontario. Throughout history, Toronto has focused on the safety and security of its water services, but now safety and security increasingly means ensuring that the City’s water systems have the adaptive capacity to respond to the changing climate and extreme weather events. To that end, in 2003, a comprehensive watershed based “Wet Weather Flow Management Master Plan” was adopted by City Council to address the water quantity and water quality impacts of wet weather flows. Subsequent to the adoption of the Plan, an extreme rainfall event in 2005 profoundly influenced the implementation of the Plan, placing a focus on basement flooding protection. Through the City’s Basement Flooding Protection Program, upgrades are being made to storm drainage and sewer systems to meet new design standards, established to mitigate the impacts from extreme storms.

This climate change adaptation strategy has resulted in the investment of almost $250 million CAD (as of the end of 2016) on infrastructure and storm drainage improvements, with planned spending in the amount of $1.5 billion CAD over the next 10 years. Chief Engineer Michael D’Andrea will present details about Toronto’s Basement Flooding Protection Program, focusing on the adaptive management philosophy, infrastructure enhancements, and policy considerations of the Program.
