Thousands of people will hit the streets of Isla Vista for the unsanctioned party called Deltopia in just four days.
"Deltopia here we come," said Brandon Peterson, a UCSB student.
In 2013, 15,000 to 18,000 people packed the small college town.
"Last year there were more than 20 people arrested, more than 40 people transported to the hospital. We had a beautiful young woman from Cal Poly fall off a cliff and die the night before and we had a balcony collapse and several people were injured. So this definitely can be a dangerous event," said Kelly Hoover with the Santa Barbara County Sheriff's Office.
Emilie Beck and Erika Van Sickel have been at UCSB for four years. They said they try to stay away from the masses of people.
"I'm looking forward to it but what we typically do is hide out in our friends houses and just don't really get involved in the madness around here," said Beck.
This year more than 100 law enforcement officers, including some from Lompoc, Santa Maria and Cal State Channel Islands, will try to keep things under control.
"As long as they aren't too strict, I think it's good. They are usually pretty nice. I feel like they are out to help us," said Van Sickel.
For DJs and bands hoping to set up on Del Playa to play to the crowd, a permit is required.
"That's all anyone can talk about right now. It's just how are we going to go around the rule," said Peterson.
"We will be enforcing a festival ordinance which would make that a misdemeanor offense," said Hoover.
It's not known exactly how many people will show up Saturday, but more than 10,000 people on Facebook said they will be there.
"I mean it's a little crazy. The streets are completely packed but it's kind of tradition," said Van Sickel.
