 Another storm rolled through Edmonton on July 30, 2016, flooding Whitemud Drive and stranding motorists. City of Edmonton officials are releasing details of a suggested $2.6-billion flood mitigation plan to protect neighbourhoods against a one in 100 year cloud burst. These are storms that typically hit only parts of Edmonton at a time – about a five square kilometre area at a time – but they quickly overwhelm sewer lines in older areas, flooding basements and floating cars. Storms like this caused 4,000 basements to flood in Mill Woods in 2004, and 1,200 basements in the central southwest and Mill Woods in 2012. New maps pinpoint storm water ponds and deep sewer upgrades across the city as Edmonton seeks to protect residential basements and city infrastructure in 160 older neighbourhoods. More information on the suggested $2.6-billion plan is expected at a news conference early Monday afternoon, but the new report lays out several options for council. A cheaper $2.2-billion option would protect neighbourhoods only against a one in 50 year storm (a storm that has a 2 per cent chance of happening every year). Scaling up, council could also opt for a $4.7-billion list of projects to protect against a much larger storm covering up to 20 square kilometres. But Edmonton has never seen a storm like that before. Officials recommend the $2.6 billion option. Those projects could be built within 45 years if Edmonton spends $60 million a year. Spending $120 million a year would get all neighbourhoods projected within 22 years. It's unclear exactly what that means for utility rates. This report is heading to Friday's utility committee meeting for debate, where councillors will also look at protecting patches of Whitemud Drive and Yellowhead Trail from flooding. If council agrees with city officials, Epcor will decide which projects should go first after it takes over Edmonton drainage. The city-owned company will report back to council with that prioritized list of projects in 2018. estolte@postmedia.com twitter.com/estolte Check out the drainage projects proposed under the $2.6-billion plan on the map below.
