BANKING/FINANCE

Frank T. Harrison has become chairman of California City Bank in Orange and its parent company, California City Bancorp, succeeding Thomas Day in both positions.

Directors installed Harrison, a bank spokeswoman said, after Day decided not to run for reelection to the boards.

Harrison, 44, of Anaheim, owns about 1% of the parent company’s stock and has been a director on both boards for the last three years. He operates a Corona company involved in residential construction and sheet-metal manufacturing. He is also a nationally ranked water skier--11th in his division.

Day, 45, of Corona, who owns about 5% of California City Bancorp stock, cited time demands from his firm, Superior Construction in Ontario, as the reason for his decision to leave the boards after serving on them for five years. His positions were eliminated and the boards were reduced to eight members.
