Could Southwest Michigan see flooding on the scale of Montpelier, Vermont?
Images of people kayaking through Montpelier's downtown have raised questions about the flood risk elsewhere.
It’s a reasonable thing to worry about, said Western Michigan University emeritus geology professor Duane Hampton. Hampton said the frequency and severity of floods will increase in coming years due to climate change.
“What used to be 100-year flood is now more like a 50-year flood. The odds are increasing of extreme events,” Hampton said. “As temperatures go up, there's more water in the atmosphere, which means rainfall event — severe rainfall events are more frequent.”
However, Hampton said the difference in terrain between mountainous Vermont and not-so-mountainous Southwest Michigan would make a flood event on the scale of Montpelier unlikely here.
Although we may not see a Vermont-style flood, Cass County Drain Commissioner Jeff VanBelle said the increasing frequency of high-intensity rain events has led to an increased emphasis on flood prevention infrastructure.
“We're having to increase the size of pipes, we're having to increase stability of structures, because if they become inundated, they can get swept away,” VanBelle said.
“I'm not aware of any drain commissioner in this state that when they're doing a project isn't saying, hey, maybe we better oversize this a little bit.”
When it comes to Cass County’s ability to meet this increasing risk, VanBelle said that while he believes that while a prolonged severe rainfall would pose a problem, the county is prepared for most flooding events.
