D.C. City Council panels recommended yesterday using fiscal 1986 budget funds to provide alternative programs for criminals, trash cans for 30,000 homes and new street signs.

All of the committee suggestions will be considered by the full council later this month.

The council's Committee on the Judiciary recommended that the city set aside $86,000 for the Department of Corrections to establish community-based programs that would serve as alternatives to prison. The money would be taken from funds now designated for payment of settlements and judgments against the city. But the money would not be spent until legislation proposing an alternative sentencing commission has been adopted and the commission has completed its work.

The judiciary committee recommended that the agencies it reviews, which include the fire department, police department and courts, receive a total budget of $535.6 million, $116,000 less than the mayor proposed.

Council member H.R. Crawford (D-Ward 7), a member of the judiciary committee, asked why the committee's budget report, prepared by chairwoman Wilhelmina J. Rolark (D-Ward 8), did not provide money for the study of new prison facilities. The District's jails are overcrowded and Crawford has introduced legislation that would establish a study commission to recommend possible prison sites.

Rolark, who introduced the alternative sentencing commission bill, said she will consider Crawford's request for money to fund a study commission.

Meanwhile, the council's Committee on Public Works approved a $241.3 million budget. The committee altered the budget to provide 30-gallon trash cans to all city homes that have trash-collection service but do not have the 85-gallon supercans. The cost would be $240,000 for 30,000 trash cans.

The public works committee also recommended that the city replace 1,846 street signs at a cost of $92,000 and spend $98,000 to hire six new employes to enforce residential parking regulations. Funds for all of the proposed changes would be transferred from the Office of Management Services and the Public Space Management Administration.

In other action, the Committee on Government Operations recommended that the $107,070 requested for three staff positions for the Office of the Inspector General be given instead to the D.C. auditor's office. William R. Spaulding (D-Ward 5) said the shift reflects expected council requests for audits of city programs.
