Katrina Foley, who has sat on the Costa Mesa City Council and the Newport-Mesa school board for almost three weeks, officially resigned her council seat Thursday.
The resignation, which Foley e-mailed to City Manager Allan Roeder and City Atty. Kimberly Hall Barlow, will take effect Friday.
"I had some unfinished council business to attend to, including weighing in on the appointment of Tom Hatch as the new city manager," she wrote in an e-mail to the Daily Pilot. "I'm ready to move on in my new role as school board trustee."
Foley, 43, served on the council for six years before running for the seven-member Board of Education.
On Nov. 2, she defeated incumbent Michael Collier for the Trustee Area 2 seat, garnering nearly 55% of the vote.
In the days leading up to the election, some questioned if she could hold both seats. She contended she could, although ultimately she decided she would not and made that clear to the voters, although she didn't make her resignation official until Thursday morning.
