Seven weeks after beginning City Manager Alan Tandy's yearly performance evaluation, the Bakersfield City Council finished it in a 110-minute closed session during a rare special meeting Wednesday, finally reaffirming its support for the city's top official of 22 years. The council also unanimously approved 1.5 percent cost-of-living raises and the requirement of half-percent retirement contributions from the 64 members of Bakersfield's management unit, including department heads -- and Tandy.
