Fort McMurray plans to build up flood defences

Fort McMurray is in the early stages of a flood prevention plan that could see much of the town site surrounded by a fortress of flood walls.

'We have been studying this issue for quite some time,' says project manager

In 2013, a flood inundated downtown Fort McMurray. The city is now in the pre-design phase of a new flood mitigation plan.

Fort McMurray is in the early stages of a flood prevention plan that could see much of the town site surrounded by a fortress of flood walls.

Downtown Fort McMurray sits at the point where the Athabasca and Clearwater rivers meet and has a history of flooding.

City engineers presented their flood mitigation plan at Tuesday's municipal council meeting.

In 1977, an ice jam inundated the city with floodwater,and in 2013, a flood washed out streetsdowntownand in the subdivision of Waterways.

Waterwayswas also one of the hardest hit communities during the 2016 wildfire, with the flames wiping out 239structures.

As a condition forreceiving future provincial flood relief funding, the subdivision needs to comply with new development codes for communitiesthat sitonfloodplains.

"We have been studying this issue for quite some time," Wood Buffalo municipal project manager Maureen Nakonechny said. "As many of you know, the lower downtown site has flooded many times."

'The ice will do what the ice wants to do'

The proposal the Wood Buffalo municipality's engineering department presented to council would see a 10-kilometre stretch of flood mitigation walls and berms constructed along the edge of the downtown core to the Waterways neighbourhood.

Nakonechny estimates it could take 3-5 years to complete the project at a cost of $153 million.The project manager warnedthose costs could change.

The municipality intends to conduct public consultations before proceeding with the plan.

Coun. Phil Meagher expressed doubts aboutwhether the project wouldwork, given thepower of river ice breakups.

"All I can say is the ice will do what the ice wants to do," Meagher said.

Nakonechnyreplied to the councillor's comment saying no flood wall or berm will completely eliminate the risk of flooding, but it would certainly minimize the risk.
