The Boise Parks Department issued the permit in May and the city will collect 12 percent of alcohol sales over $2,000. Alcohol will only be sold from noon-10 p.m.
For years people have been able to consume their own alcohol in certain parts of the park.
The easy access at the 4th of July event has made some, like Heather Johnson of Meridian, hesitant to go.
"Because coming from a non-drinking family it's kind of intimidating to me just that experience," said Johnson.
Other residents we talked with like the idea of being able to buy beer during the event and think people can be responsible enough.
"Yeah I would probably buy it here if I knew it was being served because dragging around a cooler isn't always fun you know," said Tanner Pfeil of Boise.
No alcohol will be allowed within 250 feet of the Boise River. There are signs every few feet reminding people of where you can't drink.
Boise Police said they will be out in force making sure people are following the law, and not getting out of control.
