Walking the 100-Year Floodline: Waterloo

Waterloo Region’s urban cores have “100-year” peak floodlines, affecting thousands. In today’s climate emergency, major 100-year floods are more frequent. We can adapt. But who will be affected, and how? Green-building architect Graham Whiting’s 90- to 120-minute walk along Waterloo's floodline will trace it in sidewalk chalk, and discuss implications, opportunities and fears of water moving in our cities.
