In Federal Hill, the bars are growing — expanding into adjacent buildings and drawing more rowdy crowds than ever — but so are the complaints from the neighborhood.

A group of Federal Hill residents say the bars have gone too far, and they have sought to shut four of them down this month alone.

"It's mayhem down here," said Beth Hawks, who has run the Federal Hill boutique Zelda Zen for the past nine years. "The bars have become mega bars. … It was never like this."

Both camps say they have the upscale neighborhood's best interests at heart. The neighbors long for more family-friendly businesses and upscale restaurants, while the tavern owners say their establishments have been key to Federal Hill's success.

"Living in the city is not a quiet thing," said bar operator Marc McFaul. "That's city life. … If you didn't have the bars and restaurants, you wouldn't have any shops."

The city's liquor board commonly hears complaints about violence and noise surrounding bars, but this time the neighborhood association has gone further, also citing more obscure infractions like improper building permits and unpaid taxes. The next hearings will be held Thursday.

Stephan Fogleman, liquor board chairman, says he can't remember the last time a neighborhood challenged this many bars in a year.

Fogleman said the neighborhood protesters are "effectively asking for the death penalty" for a bar. "More times than not, the commissioners aren't going to exercise the death penalty on a license without some clear and convincing evidence that a bar is causing great harm to the community," he said.

Unfazed by the protests, some bar owners want to continue to rev up the neighborhood's nightlife, which they say will make Federal Hill more prosperous.

Last month, the Cross Street bar Stalking Horse introduced a two-story addition called 30 East, with high ceilings and lipstick red trim, which ups its total size by about 25 percent. It's run by McFaul and his family, who also oversee the sprawling Ropewalk Tavern and, farther south on Charles Street, the Irish bar Delia Foley's. McFaul and his brother, who took over the Ropewalk Tavern in 1995, say the neighborhood has considerably improved since then — largely because of the new bars and restaurants.

While this might be the neighborhood's most vigorous protest to date, it's not the first. In the past, the neighborhood association has gone to court over a live entertainment license and has unsuccessfully tried to pass legislation that would ban drinking games.

The catalyst for this latest round of protests was a St. Patrick's Day pub crawl last month at several Federal Hill bars, which brought in dozens of rowdy revelers, according to Paul Robinson, president of the Federal Hill Neighborhood Association. Robinson, who has lived in the neighborhood for 25 years, said he signed a petition seeking to pull the Stalking Horse's liquor license.

"How can I, as president of the neighborhood association, stand by and watch this happen?" he said.

While it's rare for city bars to lose their licenses — typically, a license is revoked only after multiple violent or drug-related incidents — that hasn't stopped some Federal Hill residents from trying, according to Fogleman.

The Federal Hill residents sought to have the restaurant and bar Ryleigh's Oyster shut down because of back taxes and fees, but withdrew the petition the day of the hearing. "I don't believe we've ever had a protest on that before," Fogleman said.

Federal Hill's offenses pale in comparison to neighborhoods such as Mount Vernon, where the now-closed Suite Ultralounge was linked to armed robberies, stabbings and a shooting, and downtown, where two men were killed — one of them a plainclothes police officer — in a parking lot outside Select Lounge. In Federal Hill, nuisance crimes, such as tipped-over flower pots and public urination, are far more common.

After a Ravens game in December, an argument outside the Stalking Horse led one man to throw a piece of metal railing at another man, striking him in the chest, McFaul said. The police classified it as a stabbing, and it became the first violent incident associated with Stalking Horse, he said.

"I don't know what else we could have done," he said.

The capacity of bars in Federal Hill continues to increase. The owners of MaGerk's are planning to merge two bars on the south side of Cross Street Market into one large restaurant/bar. And in late 2008, Dave Rather opened Mother's on the Alley, an expansion that nearly doubled the size of his restaurant/bar, Mother's Grille. Rather said it's a natural progression for the neighborhood.
