SAN BERNARDINO >> A city that was threatening legal action against Insomniac less than two years ago and saw the promoter’s rave-style events leave the city will welcome them back for a two-day festival starting Friday, but with precautions.

There are no hurt feelings, Insomniac spokeswoman Jennifer Forkish said, and the expectation is that fans will have the experience they used to enjoy, but residents won’t have the complaints about noise and other issues that strained relations earlier.

“Our fans really love the Orange Show as a venue — it offers a great mix of indoor and outdoor,” Forkish said. “We haven’t had a festival there in a while, and I think some of that was to allow us to re-evaluate the things we need to do to be a good neighbor.”

That includes an email address and phone number that will both be checked throughout the show to monitor noise complaints: info@insomniac.com and 909-888-6788, Ext. 421.

New technology will allow frequent and precise adjustments to the sound level as comments from the community come in, she said.

Some people are still skeptical, though, including Councilman John Valdivia, whose ward includes the Orange Show Events Center and the homes that surround it.

“We’re poking a sleeping bear,” Valdivia said. “Residents in my ward have suggested very vocally that raves present two problems. The first being the large noise issues. The second being the magnet problem, that we attract these folks to our community.”

The large crowds, Valdivia fears, will increase crimes as well as car accidents and crashes.

This summer, City Attorney Gary Saenz and the attorney for the National Orange Show Events Center came to an agreement to lessen problems from large outdoor music events. The five-year agreement would have imposed five pages of requirements, including limits on hours and sound levels. One security officer would be required per 100 attendees, in addition to whatever measures the San Bernardino Police Department deemed necessary, which the Orange Show would require promoters to reimburse.

When it came to the City Council for a vote, Valdivia, who said it was negotiated behind his back, moved to table it. The vote to table was unanimous.

For years, Insomniac has put on electric dance shows like Escape from Wonderland, as this event was previously known — with stages featuring well-known disc jockeys and thumping music, as well as mazes and other Halloween attractions — in the San Bernardino area.

In 2010, that brought more than $3 million in economic development to the area, according to an estimate from Beacon Economics LLC, a Los Angeles-based economic analysis firm. In 2011, that jumped to $11.9 million and roughly $840,000 in state and local tax revenues, with more than 85 percent of attendees traveling from outside the San Bernardino area, Beacon concluded.

Organizers say there are no analyses of the next two years, including in 2013, when it was held at San Manuel Amphitheater in Devore.

Valdivia contends that holding it in Devore gives the city the same economic benefit but without the cost.

“I’ve talked to several restaurateurs, and they’ve told me they’re staying in our (hotel) beds, so we’re still getting the revenue booked, and at the same time they’re shuttling — many have exclusive agreements with bus companies out to Devore,” he said. “Bartenders I’ve talked to say they aren’t here to party in our bars, they’re here to sleep, eat, shave and get rested so they can go out to Devore.”

The 2011 estimate pegs the spending by Escape attendees at $2.7 million for food, nearly $1.2 million for retail, and more than $1.9 million on accommodations, among other categories. Entertainment totaled $1.9 million, based on 6,031 surveys of attendees. Beacon did not include the cost of tickets to the event in that number, reasoning that much of that money will likely leave town.

Questions were asked about San Bernardino County, not the city specifically.

The announcement that Insomniac was leaving Devore came before they reached any agreement in San Bernardino. CEO Pasquale Rotella said at the time San Manuel was a beautiful location but couldn’t handle larger events.

About 40,000 people are expected to attend, according to Forkish.

Dan Jimenez, National Orange Show CEO and general manager, said the Orange Show venue is favored among concertgoers because the sound stages are so close together, and parking is on pavement and relatively close.

“Also there is not a 3.5-hour wait to leave like there has been at Glen Helen,” he said. “The city should welcome this. It brings in a lot of business.”

Even the construction phase is benefiting restaurants near the NOS, he said.

Area hotels have been virtually sold out for about two weeks, he said.
