A BENDIGO business owner says a recent redevelopment of Mitchell Street caused his shop to flood. 

Shane Robertson, who owns the PepperPot in Bath Lane, said the front of his store was inundated with water following the deluge in Bendigo on Friday. 

He said flash flooding had caused damage to his floating floorboards and stock, with the total cost of repair in the thousands. He said to repair the damage he would lose two days of business.

"It's a lot of work to fix. It really causes a headache," Mr Robertson said.

"We are going to have to rip up all the floor which means moving the stock. It's frustrating."

Mr Robertson said a section of Bath Lane at the Mitchell Street end had been lowered on the right side during the redevelopment last year. 

He said a gutter outside of his store had also been lowered. 

Mr Robertson said the gutter had to deal with water from Bath Lane as well as water from Mitchell Street.

"They lowered the road and the gutter can't cope with the Mitchell Street water and Bath Lane," he said.

"It's like a giant sink hole. The gutter just couldn't deal with the influx of water."

Mr Robertson said the store had been operating for 35 years and had never flooded, not even during the floods in January of 2011. 

"It's the only thing that has changed. They have made things worse," he said.

Mr Robertson said the shops on either side of his, Days of Leisure and PH Property, had also been inundated with water. 

The redevelopment of Mitchell Street cost about $3.8 million and was aimed at improving one of Bendigo's busiest thoroughfares.

City of Greater Bendigo Mayor Peter Cox said Mr Robertson's concerns in relation to the Mitchell Street works probably needed to be looked at.

"I'm very happy to look at it with him," he said.

"We probably need to look at design there."

Mr Cox said he was committed to addressing any issues that had arisen as a result of Friday's floods.

"I have called for people that have had their backyards or carports or gardens damaged to come forwards and I'm making a list of those," he said.

"I really want to hear from everybody, particularly if water's got into their building, whether it’s a home or a business. 

"If council's going to address all these issues we need the list because if we don't know about it we can't address it."
