Hurricane Hazel in 1954 killed 1,000 people in Haiti and the Dominican Republic. It progressed up through the United States with predictions that it would die out, but it kept going clear to Canada. Forecasts for Toronto were for rain. Just before midnight people in Toronto were surprised to see streams and creeks overflow their banks. More than 80 people were killed. Toronto city planners used Hazel's high-water lines as a benchmark for zoning. Land below the water line is zoned as parkland; no one is allowed to build homes or live there. Their flood zone is now one of the largest interconnected park and wildlife sanctuary systems in the world. Can New Orleans learn anything from Hurricane Hazel? Can Utah, with its constant flooding?
