Super Bowl XLIX is in the books and the dust is settling in Glendale, Arizona, but the event's economic impact on the city is still being determined.

Fans gather outside of University of Phoenix Stadium prior to Super Bowl XLIX between the Seattle Seahawks and the New England Patriots on February 1, 2015 in Glendale, Arizona.

The Arizona Super Bowl Host Committee estimates the event had an economic impact of more than $500 million in Glendale, David Rousseau, its chairman, said. The committee bases its projection on a study conducted by Arizona State University examining the economic impact from Super Bowl XLII in 2008, also held in Glendale.
