NEW YORK (

TheStreet

) -- New York City Mayor Michael Bloomberg unveiled his nearly $66 billion revised budget plan on Friday that doesn't raise taxes but will include layoffs of thousands of city workers.

A few of the city funding cuts announced Friday would include 15% for parks and recreation, nearly 12% for libraries and 9% for the children's services agency.

New York Mayor Michael Bloomberg unveiled what he called a "budget full of difficult decisions" in the Blue Room of New York's City Hall on Friday.

One aspect of the proposal that has already encountered heavy criticism is the portion that includes the elimination of more than 6,000 teaching positions.

The mayor blamed New York Gov. Andrew Cuomo and the legislature for the severe cuts.

"We are not immune to the realities in Albany and Washington. And the reality is, both places are keeping more of our tax dollars to close their own budget deficits," Bloomberg said. "I am sympathetic to their need for budget cuts, but actions taken to close their deficits came without changing the burdens they impose on city taxpayers."

The plan would cut 6,166 public school teachers from the largest school system in the U.S., which has 75,000 teachers.

He also noted that the state budget reduced education funding to the city by $1.2 billion in 2012, representing the largest single year reduction in funding for city education.

"The state continues to disinvest in education in New York City," the mayor said.

The budget plan would also decrease funding for the fire department by about 2%, the police department would lose about 1%.

Bloomberg said that while the proposal for the full year of 2012 "presents a balanced budget," the city will "still face budget gaps of approximately $4.8 billion in fiscal year 2013, $5.1 billion in fiscal year 2014 and $5.3 billion fiscal year 2015."

Bloomberg, a political independent, now faces the challenge of negotiating a balanced budget with the City Council that will pass by June.
