A preliminary study estimated that the Labor Day weekend music fest generated $10 million for the city.
Nutter also announced that the event did not cost taxpayers a dime.
That's because festival promoters, including rap star Jay-Z, paid more than $500,000 to cover all municipal costs.
The music festival featured more than two dozen acts performing across three stages, including Pearl Jam, Run DMC, Odd Future, and Dirty Projectors.
