When reached by phone at her home Monday afternoon, Lloyd said she had nothing to say "at this time."
Lloyd, who was perhaps most publicly visible after the September 2009 floods, joined the county in July 2003 as manager of the EMA.
At that time, her name was Lanita Wakefield. She later married Mickey Lloyd, who until last year was the county's director of public safety.
She was promoted to deputy director of the Cobb agency in 2004, the same year she earned her state certification in emergency management, according to a biography on the county's website.
Before joining the county, she worked for the state of Georgia for nearly two decades, including a stint in the state's homeland security department.
According to the county's website, under Lanita Lloyd's direction, Cobb County's CERT program - an acronym for Community Emergency Response Team - has grown to become a model program for the state of Georgia and beyond.
Mickey Lloyd resigned as director of the county's public safety department last July 30, amid allegations he embellished his service in the Navy and lied about medals earned during the Vietnam War.
Mickey Lloyd was hired in January 2003, after serving two years as deputy commissioner of Georgia's homeland security agency. He had previously spent 29 years with the Atlanta Police Department, where he retired as deputy chief.
