Widespread destruction of Fort McMurray homes largely preventable, report says
'Homeowners do need to take more responsibility,' says report author
A new report concludes the widespread destruction of homes in the Fort McMurray wildfire was largely preventable.
"The total number of homes lost at Fort McMurray would have been far fewer if there had been more widespread adoption of FireSmart risk-reduction practices by homeowners," according tothe reportby the Institute for Catastrophic Loss Reduction.
FireSmart Canada is a national program that promotes measures to reduce wildfire risk.
The Fort McMurray wildfire in early Mayburned more than 2,400 structures and nearly 600,000 hectares of forest.
AlanWesthaver,awildfire management specialistand author of the report,investigated thehard-hit neighbourhoods ofBeacon Hill,Abasand, Thickwood and Timberlea.
In his report,Westhaversaid he "discounted" direct contact from flames or radiant heat of the forest fire as being "significant sources" of home ignition. Instead, he found that most homes were likelyignited bywind-driven embers in areas of the citywhere the fire made its "transition from forest into urban neighbourhoods."
"Once established, the fire would have spread from structure to structure as an urban conflagration, accounting for the majority of home losses," according to an abstract of the reportWesthaverwrote.
Report points to FireSmart safeguards
During his field work in the cityfromMay19 to 28, hecompared homes that burned to those that did not, and saidin 90 per cent of the cases homes that survived had adoptedFireSmart principles, unlike those that ignited.
Those solutions, he said, include selecting less flammable vegetation and breaking up pathways fire can follow bypruning lower branches, moving firewood piles and recycling away from the home and using topsoil instead of wood chips.
"Homeowners do need to take more responsibility," said Westhaver. "Most of these things can be accomplished by homeowners with a rake, a pair of pruning shears, and a simple understanding of how fire spreads."
Westhaver's report also notes that overall, the buffer zone between neighbourhoods and the forest was sufficient.
"We all recognize that this is an unbelievable tragedy for the residents of FortMcMurray," Westhaver said."Anything that we can do to learn lessons from their tragedy and prevent it in the future is very, very important that we do that."
