Mayor Marion Barry yesterday proposed revising the District's current-year spending plan to increase funding for such programs as public housing repairs, summer jobs, drug abuse prevention and a continuing battle against potholes.

Barry sent the D.C. City Council a midyear financial report that estimates the city will receive $41.3 million more than originally anticipated in revenues for fiscal 1985, which ends Sept. 30.

The city will get more than it expected in sales and income taxes, with some of that increase offset by money it had expected from AT&T but which it cannot get because of the telephone company's divestiture.

The revenue increase represents less than 2 percent of the city's budget.

But it enabled the mayor to submit to the council yesterday a revised fiscal 1985 budget that is balanced for the fifth year in a row, covers a number of increases in program costs and still promises a reduction of $20.1 million in the city's accumulated general fund as mandated by Congress.

The council must approve any revisions in the 1985 budget. Under the yesterday's proposal, the original budget total of $2.12 billion would be increased to $2.16 billion.

The proposed changes include increasing spending in some areas by $41.9 million, decreasing budget levels in some areas by $6.8 million and shifting $15.9 million in funding.

The decreases are primarily in contributions to the teachers' retirement system resulting from new estimates on how much will be needed in future years to cover mandated benefits, which will not be affected, and reduced interest costs. These changes will not affect any program levels, said D.C. Budget Director Betsy Reveal.

Under the proposals, funds would be shifted from the teacher, police and fire retirement funds and the Metro system to the public schools, fire department, public library, judges retirement, D.C. National Guard and public works. They will cover the cost of bonuses, overtime, uniform and equipment purchases, as well as pothole repairs.

Barry proposed increases in these program levels: $5 million for public housing repairs, $1 million for summer youth jobs, $1 million for pothole filling, $725,000 for drug prevention and treatment, $200,000 for job and health programs for Hispanics and $112,000 for senior citizen nutrition centers.
