Oakland Mayor Ron Dellums told the city council Tuesday the projected deficit for the next fiscal year is now up to $50 million.
Dellums sent the news in a letter preparing the council for budget workshops next month.
The city is already dealing with a $37.5 million shortfall this year, so even deeper cuts are expected.
"We are looking at longer term projects and services we might not be in the business of doing any longer; those are some of the drastic things," Dellums' Chief of Staff David Chai said.
Chai declined to say just what those cuts could be, but did say many short-term measures are already being implemented.
Oakland city offices, for example, are now closed through January 5, 2009.
Only emergency services will be available.
