An Italian festival that’s been a staple of the Bloomfield area in Pittsburgh is coming to Butler next year, after council unanimously approved a contract with the group Little Italy Days on Monday.

The four-day event will be held over Labor Day weekend in 2017, and will include vendors and food merchants.

According to the contract, festival organizers have agreed to pay a portion of the overtime costs associated with public safety and street sweeping services during the event. Another portion of the cost will likely be paid for through a grant, council members said. The city will probably end up footing the bill for about half of the public service overtime costs associated with the festival, said Mayor Tom Donaldson.

“This is going to cost the taxpayers some money on overtime for the services we render,” he said.

The majority of those costs would likely be incurred through police overtime, said council member Kathy Kline. An estimate of the full overtime costs associated with the festival wasn’t immediately available Monday.

Sal Richetti, who is one of the festival’s producers, said that anywhere from 80 to 180 vendors could set up shop in the city during that four-day span next year. The festival would close down Main Street each day, and still needs to receive PennDOT approval because of that aspect of the event. But Richetti and another organizer of the festival told council members earlier this year that they would begin seeking sponsors for the event and working to promote it as soon as they had a signed contact with the city.

“This is for the locals and for the businesses,” Richetti said. “And we want them to enjoy this type of celebration and make it a family fun, festive atmosphere.”

Mayor Tom Donaldson said he wants businesses in the city to consider opening their shops during the festival hours, which Richetti said would likely be 5 to 9 p.m. that Friday, noon to 9 p.m. Saturday and Sunday, and noon to 6 p.m. Monday.

According to the contact approved Monday, the festival vendors would be required to tear down and set up their booths each day, so Main Street would reopen following the event each day.

Richetti also said he hopes the city’s businesses support and take advantage of the event, which organizers have said could draw as many as 30,000 people to Butler.

“We would want the businesses of Butler to participate and capitalize on the people that are going to be coming into town,’ he said.
