The federal government will provide more money for summer youth jobs in the District, it was announced yesterday, but the aid may have come too late to help the city's program very much.

City officials announced yesterday that the Carter administration will provide federal funding for 1,067 more summer youth jobs, raising to 11,378 the total number of federally financed jobs for young people here. But the officials said that the District government has not yet succeeded in assigning youths to all the jobs that are already available.

The $867,634 in summer youth employment funds for the District is part of a new, $96 million federal jobs program for 31 cities across the country. The District's share total $4.3 million, which also includes money for some temporary and long-term jobs. The funds are designed to help counter the effects of the recession and to help ease social tensions resulting from high youth unemployment in urban areas.

The new federal funds will have no direct impact on the city's worsening budget crisis or its deficit. The funds may, however, allow city officials to go ahead with some work that might have been impossible during the budget crisis, such as rehabilitation of public housing.

The District's share of the money includes:

$2.3 million to repair and rehabilitate public housing projects. City officials said they have not yet identified which projects will be improved. This program is designed to create 191 jobs.

$1 million to fund unspecified public works projects. These funds will create 376 jobs, each lasting two months, for unemployed persons.

$55,000 to hire some 50 disadvantaged youths for the summer to maintain and repair buildings that house the U.S. Department of Health and Human Services. Much of this work will involve making these structures accessible to the handicapped.

Adolph Slaughter, spokesman for the city's Department of Employment Services, said he had no further details on the new federal funds. "I just got the outlines today," he said. "I don't know when we'll get the money."

Slaughter did say, however, that it would take "some time" to locate jobs that the federal funds can be used for -- especially in the summer jobs program. The federal youth employment funds can only be applied to jobs in the city or federal governments or with nonprofit organizations.

"Obviously, we don't have people going to work next Monday," Slaughter said."If we don't get jobs until Aug. 1 we'll put the kids to work then. At least they'll be able to get four weeks pay."

Information compiled by the Department of Employment Services indicates that as of yesterday, nearly 5,000 city youths had registered for summer jobs but were still waiting for work. More than 14,000 youths have already been placed in jobs, the figures indicate.

Slaughter said the city had already located enough jobs for all the 19,085 youths who have signed up for the program so far, and that the 5,000 youths who are still waiting would soon be at work. He said that the department intends to continue registerating youths for the program in the coming weeks with an eye to filling the latest batch of new jobs.
