Protecting DVP from floods would be costly

TORONTO -- The city will have to address frequent flooding on one of it’s busiest arteries into downtown but it won’t be cheap, Deputy Mayor Norm Kelly said Thursday.

While providing an update to media after Wednesday night’s torrential downpour, Kelly acknowledged the city may have to lean on the provincial and federal governments for help to find long-term solutions to the flooding problems on the Don Valley Pkwy. While he couldn’t say which improvements were needed, or how much they would cost, he said the flooding is becoming more frequent.

The sudden storm Wednesday caused the closure of the highway after water levels swelled by a metre in an hour, spilling over onto the road.

“You’re talking large numbers,” Kelly said. “Any review of the strategic responses has to be very thorough. The costs will have to be looked at very, very, very carefully.”

Steve Buckley, Toronto’s general manager of transportation services, said the city has been examining a number of options since last summer’s flooding. Among them putting check valves on the highway to block water or even changing the entire profile of the road, in effect, raising it above the floodplain.

“Changing the profile of a major freeway can be disruptive and we want to make sure if it does cost a significant amount of money that it is indeed going to reduce the risk of events.”
