Alexandria’s top staff ranks, depleted by recent retirements and resignations, were refilled Friday when city manager Rashad Young announced the appointments of four city officials to new jobs.

Laura Triggs, deputy director of finance and chief financial officer, has been promoted to deputy city manager, taking the spot left vacant by Michele R. Evans, who retired Friday.

Triggs will be succeeded by Kendel Taylor, who works in the finance department, and who has been named acting director of finance.

Yon Lambert, deputy director of operations in the transportation department, has been named acting director of Transportation and Environmental Services. He will take over the department Sept. 1, filling the position vacated by Rich Baier, who is moving to another local government job in Florida.

Craig T. Fifer, who has been acting director of communications and public information since February, when Tony Castrilli left for a similar position in Fairfax County, has been appointed to director.

Karl Moritz was earlier appointed acting director of planning and zoning, taking the position left vacant when Faroll Hamer retired last month. The director of housing, Mildrilyn Davis, plans to retire at the end of the year.
