Columbia County's director of community and emergency services resigned Tuesday amid a proposed restructuring of his department.
Rusty Wade's last day on the job will be Thursday, according to County Administrator Steve Szablewski.
Mr. Wade did not return phone calls to his office, pager and home Tuesday.
Mr. Wade had worked for Columbia County since February 1992, and was the head of its largest department, which encompassed recreation, Emergency Management Agency, libraries, health department, family and children services and animal control.
County officials are considering separating the emergency and community branches, and hiring directors for each.
"We are planning to reorganize that department and he was invited to apply for those positions and I think he feels he wants to do other things right now," Mr. Szablewski said.
In the meantime, Scott Sherman will serve as the acting EMA director.
An acting community services director will be named later this week, Mr. Szablewski said.
County commissioners will vote on both appointments next week.
County officials hope to begin advertising to fill both of the positions permanently beginning Jan. 10.
Following a month of ads, Mr. Szablewski said, it would take one to three months to fill the vacant jobs.
