Borough officials say crews will be checking the sewers in the Victoria Avenue underpass in Côte-des-Neiges after a woman had to be rescued from her submerged car in a flash flood last Saturday.
The vehicle was stopped beneath the railway overpass while waiting for the traffic light to change on Jean-Talon Street West, and in the time it took for the light to turn green, the car was submerged in close to two metre of water.
The trapped driver only escaped after a police officer dove into the water, smashed the car's window and pulled her from the vehicle.
Two people who witnessed the rescue said the rookie officer who saved the woman is a hero.
City Coun. Marvin Rotrand says he's asked the borough administration and public works department to look into the problem.
"It may be an isolated incident, but we will do our work to make sure that it was an isolated incident and that there was nothing that could have been humanly done to change this situation."
Rotrand says the Victoria Avenue underpass was rebuilt 10 years ago, and the sewage system beneath it should be in good condition.
He says the borough cleans the sewers beneath the underpass annually and is unaware of any such previous incidents.
