Mayor Marion Barry's transition team, in its final report, has recommended a wide range of policy changes that would substantially strengthen the mayor's hand in dealing with the important and politically sensitive issues of spending for public education and economic development.

The document also adopts earlier task force recommendations for widespread cuts in welfare and other benefits, and calls for a virtually total revamping of city agencies and the mayor's executive office to create three deputy mayors and appoint a chief of staff. Such a staff structure would greatly diminish the role of the city administrator.

Meanwhile, as part of the changes under way in the transition to a second Barry term, more than a third of the city's 52 top officials who were asked by the mayor to submit their resignations after the Nov. 2 election will be reassigned or will leave government, according to District Building sources.

The transition report marks the completion of five weeks' work by nine task forces and a 28-member steering committee of city officials, businessmen and civic leaders headed by Ivanhoe Donaldson, Barry's top political adviser and the chief architect of his first term.

The document was sent to the mayor last week and he is considering which of the recommendations to adopt. Many of the proposals, which the report said could result in total savings of $250 million annually, significantly could affect the quality of services taxpayers receive. Some of the changes would require D.C. City Council approval.

"Although all of the recommendations may not be realistic, they are proposed actions that we felt compelled to make at this time," the report said.

The transition proposal calls for Barry, a frequent critic of the school board's spending policies, to appoint a new commission on educational programs and finance to help him develop a master plan for school spending for the remainder of the decade. Also, the D.C. Office of State Education Affairs would be transferred to the mayor's office from the Department of Human Services, to give him a more direct hand in monitoring education costs.

Both of those changes would give the mayor increased information and staff support on education issues, allowing him to take a more active role in proposing policy. Currently, the school board originates spending proposals for the coming year, which must the be approved by the mayor, the City Council and Congress. Once a new spending level is set, the school board determines how that money is to be spent.

The task force's public education recommendations include eliminating authority given the school board earlier this year to dispose of surplus school property; limiting the popular $5.7-million-a-year school transit subsidy, now available to all public school students, to handicapped and poor children, and doubling tuition charged students at the University of the District of Columbia.

"The mayor, as the chief elected official, should become involved in public education policy development and the coordination of general governmental programs with those in the public education system," the task force study stated.

The Rev. David Eaton, president of the school board, could not be reached yesterday to comment on the recommendations.

In urging that the mayor take a much stronger hand in creating jobs and boosting economic development, the report concluded that the District "suffers a poor image in the business community that must be counteracted immediately."

All city departments and agencies involved in planning, development, licensing, job training, business retention, conventions and tourism would be brought under the control of one of the new deputy mayors.

In providing a highly detailed blueprint for restructuring the administration, the report also provides several pointed criticisms of such city services as water billing and public housing management--areas in which Barry had claimed major improvements during his reelection campaign this year.

At the same time, it stressed that nonessential government services must be sharply curtailed in an era of diminished local and federal revenues and increased costs.

"Too many services and subsidies are routinely provided to individuals and families who are financially secure," the report said.

The report recommended that Barry appoint three new deputy mayors to assume direct-line responsibility for finance and revenue, government operations and economic development -- responsibilities that now rest primarily with City Administator Elijah B. Rogers.

Rogers is expected to leave the administration early next year, shortly after Barry is sworn in for his second two-year term in January. Although the city administrator's office was created by law to oversee the day-to-day operations of the government, Barry has the executive authority to downgrade the importance of that office.

Barry is expected to appoint City Comptroller Alphonse G. Hill deputy mayor for finance and revenue. Thomas M. Downs, director of the Department of Transportation, is under consideration for one of the other two deputy mayor positions.

Courtland V. Cox, now a special assistant to Barry and former executive director of the Minority Business Opportunity Commission, is expected to be named staff director of Barry's realigned executive offices.

Many of Barry's special assistants are expected to leave city government or take new assignments outside the mayor's office, including Kay C. McGrath, Patricia E. Miner, Lillian A. Sedgwick, Warren Graves and Mary Lampson, sources said.
