The mayor and the fire commissioner Thursday raised the specter of layoffs among the Bravest and the shuttering of firehouses as the city tries to plug a gaping budget hole.

Mayor Bloomberg's demand for a $1.4 billion all-agency budget slash for the next fiscal year imposes a $95 million hit on the FDNY.

"I'm hoping we don't have layoffs, but $95 million is a huge additional budget cut, so everything will have to be on the table and we'll see," Fire Commissioner Nicholas Scoppetta said.

Bloomberg warned of possibly closing more firehouses as he dukes it out with the City Council over his call Tuesday for an additional 7% cut in next year's budget.

He and the Council are also sparring over the mayor's refusal to mail long-overdue $400 property-tax rebates.

"There's no magical pot of money," the mayor said Thursday. "The next cut is firehouses. There's just no other place to do it."

He noted that the FDNY already has axed next month's academy class of 110 new trainees, shut a firehouse on Governors Island and reduced night staffing at four firehouses.

During the city's 2003 budget crisis, Bloomberg sparked a prolonged furor when he closed six fire companies.

Asked later about possible firehouse closings, Scoppetta commented, "When he [the mayor] says that might happen, that might happen."

Scoppetta warned that drastic actions will be unavoidable in all agencies if the Council doesn't agree to withhold the rebate, worth $256 million, and end the 7% property tax relief, worth $576 million.

But there was no sign of give Thursday by Council Speaker Christine Quinn, at least on the rebate issue.

She said the rebate is a legal obligation and the Council won't renege, although she conceded the checks can't go out in time for Christmas at this point.

Several Council members have sued the city to force payment, but at a hearing Thursday, state Supreme Court Justice Philip Minardo granted city lawyers a one-week adjournment.

He urged the two sides to resolve their dispute soon, or "the court will decide."

Controller William Thompson said Thursday that the city will lose 5,000 more private-sector jobs than his prior estimate of 165,000 from this July through December 2010.

He also said Wall Street bonuses this year will decline to a level not seen since 2002, the year after 9/11.
