Highland Park has long grumbled that its resident treasure, the Ravinia Festival, has a downside that costs the city money for things like road and parking lot maintenance–complaints that the Festival seemed to meet with a deaf ear. But when city officials recently threatened to resort to an amusement tax on Ravinia tickets, the message came through loud and clear. Under a 10-year agreement signed last week, Highland Park will receive a “municipal admissions fee” of five percent of the Festival’s gross ticket sales. Based on last year’s gate of nearly $15 million, that could mean about $750,000 for the city in 2009. Expect to see the fee affect pop concert prices disproportionately, since there will be no increase in prices for Chicago Symphony Orchestra events–lawn admission for the CSO will remain $10. It’s curtains, however, for the YEA! Highland Park concert, an annual end-of-the-season benefit that raised $254,000 last year for local youth, art, and education activities. Instead, the festival will donate 300 tickets for a tented YEA fundraiser at one of its scheduled concerts. The city’s also promising to donate an unspecified portion of its new bounty to YEA.
