The D.C. City Council moved a step closer yesterday to approving three proposals that would allow the city to issue salary bonuses to more than 24,000 of its employes next month.

Meeting as a committee of the whole, the council placed the proposals on the agenda for its Dec. 4 meeting.

If the council approves the bonuses as expected, city officials said that they would be able to issue the one-time bonus checks by Dec. 18.

The salary bonuses, 3 percent or $500, whichever is greater, would total $11.1 million and would be financed by anticipated increases in revenue from deed recording, inheritance and deed transfer taxes that were not included in the original fiscal 1985 budget.

The bonuses would be distributed to three groups of employes.

The first group, 13,640 union employes, have negotiated a three-year agreement that must be ratified by the council. In addition to the bonus, which would total $5.5 million, the employes would receive a 3.5 percent pay increase in base salary in 1985, a 4 percent increase in base salary in 1986 and a 1.5 percent increase in base salary in 1987.

The second group is made up of 10,644 employes who are not covered by collective bargaining.

Their pay bonuses will total $5.6 million. The third group, 400 employes at the University of the District of Columbia, will receive $400,000 in bonuses.

Bernard Demczuk, the District legislative representative for the American Federation of Government Employees, said yesterday the unions are pleased that the council plans to approve the bonuses. The unions, however, plan to lobby to get the city to issue the checks before Dec. 18, he said.

Demczuk said that the council and the mayor's office could have completed action on the pay proposals sooner if there had not been initial confusion over how the bonuses would be funded.
