D.C. Mayor Marion Barry is giving some of his senior aides incentive bonuses totaling $42,500, including $10,000 for outgoing City Administrator Elijah B. Rogers.

Barry also has decided to give $5,000 awards to six other top officials: Police Chief Maurice T. Turner; former budget director Gladys W. Mack; former planning director James O. Gibson; personnel director Jose Gutierrez; transportation director Thomas M. Downs, and former controller Alphonse G. Hill, who recently was named deputy mayor for financial management.

David A. Splitt, director of documents, who served temporarily as executive director of the D.C. Board of Elections and Ethics during last November's balloting, is to receive $2,500.

Each of the officials is paid more than $56,000 in salaries.

In response to an inquiry about the unpublicized bonuses, Barry's press secretary Annette Samuels listed the officials who are to get them and said that the "incentive awards were given for 1982 to the people who served this community very well."

Samuels declined to comment further on the bonuses and Barry refused to be interviewed on the matter.

Samuels said that the funds will come from the budgets of the officials' agencies.

A top Barry aide said late yesterday that the officials are to be told formally of their bonuses at a breakfast meeting next Tuesday with Rogers.

Contacted last night, Splitt and Mack said that they were unaware of their selection for the bonuses. Both acknowledged being invited to the breakfast with Rogers, but said that they had not been told of its agenda.

Gibson, who no longer is employed by the city, said that Rogers told him about the award last week. Gibson said that it was the first time he had received an award under the city's incentive award program.

Hill, Gutierrez, Downs and Turner could not be reached for comment.

Under the incentive awards program, department heads are authorized to recommend to Barry which employes should receive bonuses for outstanding performances.

"I don't think the District does enough of this," said Gibson, who suggested that the awards improve employe morale and performance.

Rogers, whose annual salary was raised this month from $58,500 to $67,200, declined to discuss his award. "It would be inappropriate for me to discuss my own personnel matters," Rogers said.

Rogers long has complained that his salary was lower than that of other top municipal managers and has indicated it is one of the reasons he plans to leave the government in May. Until this year, Congress had rebuffed attempts by Barry to raise the cap on Rogers' salary.

Downs, who served as transportation director in Barry's first term, also has been appointed to a new post as director of public works that includes responsibility for the departments of environmental services and general services.

Mack, who was Barry's budget director, has been named director of policy and program evaluation, a new position in the office of the mayor.

Gibson has left the government for a position with the Eugene and Agnes Meyer Foundation.
