Sudbury's Flour Mill area seeks flooding solution

People who live with chronic flooding are calling for action from the city, but containing water within the Junction Creek system and the large Ponderosa marsh could cost Greater Sudbury taxpayers millions of dollars.

People in flood-prone parts of Sudbury are calling on the city to find a better way to contain the waters of Junction Creek.

Claude Charbonneau said he and his Flour Mill neighbours are tired of worrying about water every spring.

He said his part of the neighbourhood serves as a kind of holding tank for floodwaters, as the storm sewers under homes fill up when the creek swells.

Charbonneau wants the city to find a way to contain the waters in the nearby Ponderosa marsh or further up stream.

"In this day and age, they have the smarts and they know how to retain this water someplace else," Charbonneau said. "So, we're looking for them to come to our help."

He and other Flour Mill residents have formed a citizens committee, under the leadership of their city councillor Joscelyne Landry-Altmann.

She says the flooding this spring was the last straw. She said it's time to find some short-term and long-term solutions, even if the bill to taxpayers runs into the millions of dollars.

"It will be expensive," said Landry-Altmann. "But you know, it's always good to spread the wealth in other parts of the city."

The city does have about $3 million earmarked for Junction Creek flood-proofing, including monies set aside in past and futureu budgets.

However, general manager of infrastructure services Tony Cecutti, said much of that money will be spent studying the problem.

Notre Dame Avenue in Sudbury, Ont. has been plagued by flooding this week. But while this spring was particularly bad, the area is usually wet at this time of year. That's because the businesses on the east side of Notre Dame are built in the Junction Creek flood plain - what's often called the Ponderosa. (Erik White/CBC)

"I wouldn't believe that would be able to solve all of the problems related to Junction Creek and flooding," Cecutti said at a recent city council meeting. 

He expects a report outlining some of the flood-proofing possibilities to be back before city council in about a year.

City engineers have already proposed a flood-proofing plan for a different part of the Flour Mill neighbourhood.

Mountain Street residents have complained that the hilltop Sunrise Ridge development above them has lead to wet basements and flooded streets in recent years.

In response, city engineers proposed a multi-million dollar plan including a flood wall and a drainage channel which would funnel water away from Mountain Street and into the Ponderosa swamp.

Hydrologist Sig Kirchhefer, who has studied water flow in the area, warned against that plan.

"You're dumping it into the Ponderosa area and you're flooding somebody else," he said. 
"So, you have to take care of your own problems, rather than pass it on the next person down stream."

Kirchhefer said there is no evidence that the flood-proofing measures the city has put in place are actually reducing flows in Junction Creek. He said in general, the growth of the city has lead to more water than ever running through the waters
