Mayor Edward Koch made public a revised financial plan today that, despite new job cuts, projects a $1.17 billion fiscal 1982 deficit.

The city has pledged to produce a balanced budget by fiscal 1982, but the gap projected in the revised fouryear plan Koch submitted to the financial control board is $63 million larger than the estimate made a year ago.

Budget Director James Brigham said that the gap -- which the city is pledged to close by cutting its payroll and other expenses -- begins to level off after 1982.

Koch and other New York officials were criticized in a White House memorandum made public last week for not making larger budget cuts last year. Federal officials have been telling the city that heavy cutbacks must be made soon to give New York a realistic chance of closing the projected budget gap.

Felix Regaty, who for more than three years was at the center of efforts to keep the city from bankruptcy, stepped down as chairman of the Municipal Assistance Corp. 10 days ago with a similar warning.

Rohatyn said that New York is in for a budget siege and that if cuts are not made soon there will be a need for "really terrifying surgery" in fiscal 1981.

Koch's plan to eliminate the projected $433 million budget gap for 1980 includes ending 6,033 jobs and increasing license and permit fees an average 10 percent.

These steps would save about $140 million. New York State has already pledged $200 million and the city is counting on Washinfton to supply the remaining $100 million.

If federal and state aid fall short of these totlas, Koch has a contingency plan that would double the 25-cent Staten Island ferry fare, abolish the city's human rights commission and eliminate an additional 800 policemen to balance the budget.

The police will lose 500 uniformed positions even without the contingency plan, but Koch said these will be replaced by the same number of civilians so that street patrols will not be reduced.

Brigham said that most of the job reductions will be made through attrition and switching workers to other jobs rather than by layoff. However, the cuts made public today do not include reductions in the semi-autonomous Health and Hostital corp.
