Toga! Toga! Toga!

The days of the “double OC” (outta control) off-campus house party may become a thing of the past in Berkeley.

City leaders are proposing new rules to reduce the fallout from large and rowdy drinking parties in everything from mini-dorms to fraternity and sorority houses that house 10 or more students around the UC Berkeley campus.

The Group Living Accommodation ordinance seeks some common-sense limits, like capping house parties at 200 people and barring Darwinian acts like climbing on rooftops. But the measure, which seems to treat young adults as if they’re children, also is a bit over the top and will be tough to enforce.

Parties where alcohol is served would have end times of 10 p.m. Sunday through Thursday and 1 a.m. on weekends. And the city would require a “responsible resident” — the equivalent of a dorm mother — to maintain the group-living property, keep neighbors informed of upcoming events, and keep underage residents and guests away from the booze.

Unless city officials are going to take a head count at the door, I don’t see how they’ll control gatherings in a campus community of 37,000 students. And if there are underage students at a party — and there most certainly will be — they’re going to get a drink if they want one.

If measures are not observed, it’s the landlords of the troubled properties who will hear about it. The city plans to cite property owners with nuisance abatement orders and — if the troubles continue — penalize them by eliminating an available bedroom for every offense.

Student government officials are up in arms over the proposal and rented a bus to bring students from campus to a September workshop on the plan. A spokesman for the Associated Students of University of California last week called the city’s proposals “draconian.”

If the city’s measures sound drastic, it’s in response to a drastic situation.

“There have been student deaths, sexual assaults and injuries,” said Matthai Chakko, a city spokesman. “These are serious problems and problem properties that lead to a significant drain of city resources.”

The city’s Fire Department was called 267 times between January 2013 and August 2015 — with most of these calls to student housing, including fraternities and dorms, the staff report says.

The report says that over the past year two people suffered “alcohol-related deaths” at UC Berkeley — one at a fraternity and one at an apartment — and that there have been numerous reported sexual assaults on and around campus.

The city’s plan is a reflection of concerns from more than a dozen stakeholders, including neighborhood associations, representatives from UC Berkeley’s athletic and administrative departments, Alta Bates Hospital, and Bay Area Women Against Rape.

Berkeley is certainly changing, or changed, because this suggests far greater control on individual behavior than most places, let alone the birthplace of the Free Speech Movement, would prescribe.

My biggest problem with the city’s plan is that virtually all of the behaviors identified in the proposed ordinance are already against the law.

Sexual assault is a serious felony crime, and there are laws on the books about serving alcohol to a minor.

The policy is still a long way from a hearing before the Berkeley City Council, and I believe the city is asking for the world in the hopes of reaching a reasonable compromise with the student community.

But instead of casting such a wide net and ensnaring the everyday student who may share a beer at home with friends occasionally, the city should focus its efforts on the dozen, or two dozen, off-campus and frat houses that are ruining the party for everyone else.
