WASHINGTON -- In between the shouts and cheers, there were cops and clean up crews.

For more than five hours, the District shut down bridges and streets to let the parade and crowd march along Constitution Avenue to the Capitals' rally.

Championship events can cost a lot of money - just ask George Washington University Sports Management and Tourism professor Lisa Delpy Neirotti.

"The biggest cost is the manpower, the police, the emergency crews and it really depends on how many streets you block off,"' she said.

District officials say the Caps' parade likely ran between $380,000 and $400,000, but that's just the preliminary estimate.

"DC Government was proud to support public safety and clean-up efforts the Stanley Cup championship parade, which were a tremendous success because of the fans, the players and the workers," said John Falcicchio, Chief of Staff to Mayor Muriel Bowser in a statement.

"Our partners at Events DC stepped up with $250,000, which covers most of the preliminary cost estimate for the parade. This past week has been a fantastic experience for the Sports Capital, and we look forward to doing it again next year. #Back2Back"

Delpy Neirotti says the early numbers are actually pretty low.

"Well, it ranges from a half million to up to three million -- that's typically what the final cost is" she said.

When it comes to Stanley Cup parades, cash flows from a variety of places: The city, the team, sometimes private companies.

Events D.C., an event venue and planning company funded in part by hotel and restaurant taxes, contributed $250,000 toward this parade bill.

The city of Chicago told us they spent around $800,000 to celebrate the Blackhawks Stanley Cup in 2013 and that's with sponsorships covered part of the cost.

The city of Pittsburgh said they don't know what the Penguins' parades cost in 2009, 2016 and 2017, but estimated amusement taxes funded a lot of it.

"The city usually obviously just assigns the necessary manpower, and then sends a bill to the team," Delpy Neirotti said.

She pointed out other championship teams have balked at the final price.

Take the Golden State Warriors, for example. Their championship parade sparked a debate with the city about who would pay what.

Months later, the Golden State Warriors agreed to pay almost $800,000 even though, they said that was "more than double the $300,000 estimate..." the City of Oakland provided.

Delpy Neirotti said the bottom line is events like this raise spirits and good feelings help raise revenue.

Monumental Sports and Entertainment told WUSA9 they are not releasing how much they expect to spend on the event.
