Mayor Marion Berry will appoint Joyce Blalock, a Pentagon lawyer and five-year resident of the District of Columbia, as the city's first inspector general, The Washington Post has learned.

The position was created by Barry in an executive order soon after he took office last January. The inspector general has broad powers to investigate allegations of wrongdoing or mismanagement in city agencies, and is expected to have direct access to the mayor.

Blalock's selection, which is subject to confirmation by the City Council, will be announced today, the first day of what Barry has proclaimed as Women in D.C. Government Week.

Florence Tate, Barry's press secretary, would not confirm or deny the appointment. The Post obtained independent confirmation from other sources.

Blalock, 49, is a native of Texas and a member of both the D.c. Coalition for Women and the D.C. branch of the National Organization for Women (NOW). She applied for the job, which pays $50,112 a year, when mayoral aides announced that they were seeking someone for it.

Blalock is branch manager of labor personnel law for the National Guard Bureau at the Pentagon. Previously she was a lawyer for the Food and Drug Administration and for the International Association of Chiefs of Police, which has its headquarters at Gaithersburg.

She also had been an assistant attorney general of New Mexico and had been in private practice with a major Boston law firm.

Blalock was graduated from the University of Texas and received her legal education at Columbia University and the University of Denver.

Divorced and a mother of three sons, she lives in Southwest Washington.

Until now, the job has been filled on an acting basis by David Legge, who had directed the municipal audits and inspection division under the old D.C. Budget Office.
