Orange County Manager Laura Blackmon is resigning at the end of June.
Blackmon will be moving to Tennessee, she said in a letter to employees.
"I know the timing of this announcement is not good, but my employment agreement with the county requires I give 90 day notice and I was running out of time," she wrote. "By the end of June I will have been here over 2 1/2 years. This is not as long as I had originally thought I would stay, but life isn’t always as we plan it."
Blackmon will remain through the current budget cycle. The county anticipates an $8.7 million revenue shortfall, and Blackmon has told staff to anticipate 10 percent cuts in their department budgets. The county began reviewing possible program cuts last week.
