Shinedown plays on the Bangor waterfront last summer. [YouTube][/caption]Waterfront Concerts has attracted more and 200,000 people and $30 million to the city of Bangor since the venue's opening in 2010, according to a new study.

People who attended the concerts spent $18.6 million locally with another $11.8 million in indirect spending, according to the study by Todd Gabe, a University of Maine economics professor.

People have spent more each year of the concert series. Gabe estimated the direct economic infusion was almost $3 million in 2010, $5.8 million in 2011 and $9.8 million in 2012.

“The number of shows has increased since 2010, and people seem to be coming from greater distances,” Gabe said in a news release. “This explains the large increase in economic impact.”

Gabe studied the zip codes of ticket buyers and found that 25 percent -- an estimated 50,000 people — lived within 30 minutes of the waterfront. About 15 percent  traveled more than three hours to attend a concert.

The study was presented to the Bangor City Council on Monday.
