Find info on basement flooding risks and extreme weather at www.cityfloodmap.com. We maintain maps of Toronto flooding during historical extreme rain events (May 12, 2000, August 19, 2005, July 8, 2013). Reported flood locations are mapped at a local street level showing flood risk before sewer improvements - data can guide insurance coverage needs and identify private protection measures by owners, buyers and developers to limit flood damages and claims. Enjoy. R.J. Muir, Toronto, ON.
