The Director of Watershed Management for the Essex Region Conservation Authority suggests residents living along Cotterie Park Road in Leamington should move out of the area.
Tim Byrne tells CTV Windsor he is concerned about the risks from flooding and shoreline erosion.
"I don't mean to sound heartless on the situation but the fact of the issue at hand is they are threatened," says Byrne. "They are threatened regularly. The threat is imminent."
Byrne says it is a dangerous situation that residents and the municipality should not take lightly.
"Should it reach any type of measurable storm intensity, there will be damage, destruction and potential loss of life," says Byrne. "It is not a what if scenario, it is reality."
The area was hit with flooding Monday night, prompting ERCA to issue Flood Warning that has been extended until Thursday.
