SLIPPERY ROCK TWP — With Slippery Rock University’s academic year — and the summer party season — under way township officials, state police and property managers say they believe new regulations meant to curb raucous parties are working.

State police in Butler, who are responsible for providing police coverage to the township, say underage drinking, disorderly conduct and public intoxication calls are key issues they deal with during the university’s academic year. Lt. Steve Russo said troopers also have responded to aggravated assaults and, last year, incidents where weapons were displayed. So far this year, Russo said, troopers haven’t had any trouble involving SRU students.

“We haven’t really had any issues to deal with up there,” he said, “and I’m hoping it stays that way.”

That wasn’t the case in 2015, when emergency responders and law enforcement made appearances at multiple parties in the township.

In April 2015 four people were hurt during “Pig Roast 2K15” at The Heights apartment complex on Route 173, including two women hit by an unoccupied runaway car, according to state police.

On Aug. 22 two university students ended up in separate hospitals with head injuries after an altercation broke out at The Grove apartment complex, during an “Epic Pool Party.” A third SRU student also was taken to Grove City Medical Center that night after suffering “suspected alcohol intoxication,” according to authorities.

Days later, on Sept. 3, emergency responders took 14 students and five visitors to the hospital with alcohol-related symptoms, called in by state police as “alcohol poisoning,” after they were called to an annual block party held at the University Village apartment complex.

The spate of incidents prompted township supervisors to amend the municipality’s zoning ordinance to require a permit for outdoor sound systems and entertainment, and also passed a stand-alone ordinance imposing penalties for so-called “nuisance gatherings.”

Richard Grossman, a community planning consultant for the township, said that so far neither of the restrictions has been tested.

“Since the enactment of it we’ve never prosecuted under it. That’s the story so far,” Grossman said of the nuisance gathering ordinance.

He said the township has issued between 9 and 12 permits for outdoor amplified entertainment since the zoning amendments were approved late last year, and has thus far not denied a permit application.

Those permits include parties at University Village, which hosts seasonal events in April and September; and The Grove, which hosts annual pool parties marking the beginning and end of each academic year.

The Grove held its latest event, a kickoff pool party, last weekend. Meagan Reed, the complex’s property manager, said she’s had no issues with the new rules and regulations and believes they place responsibility for students’ conduct where it belongs — with them.

“I think it’s really nice and will help regulate a lot of the issues that have been happening at the off-campus residences,” Reed said. “It kind of cleared the air.”

Luv Desai, property manager at University Village, did not return messages left seeking comment. The complex held a pool party last week, according to its Twitter account, and a Bloc Party Thursday, from 6 to 10 p.m.

Grossman said he believes the new rules have helped keep the events from getting out-of-hand or sparking issues with nearby residents. He said township officials hadn’t received any complaints about parties or noise since the new regulations were put in place.

“Compared to past years they’ve been much more orderly,” he said. “It’s allowed us to work closer with property owners and managers to ensure that large events don’t have spillover effects like late night noise, littering and traffic tie-ups.”

Still, despite the quiet summer Russo said he believes it’s too early to say for sure whether the ordinances have made a lasting impact.

“It’s kind of early to say whether things have changed or improved at this point,” he said.
