William E. Martin, the county's emergency management coordinator for the past 3 1/2 years, retired Wednesday.
He began in July 2003 as a contractual employee, then was hired by the county in January 2004.
The position at that time was a liaison to the Carroll County Volunteer Emergency Services Association, later evolving into the emergency management coordinator, Martin said.
The job's main function is emergency operations planning and handling of Homeland Security grant funds through the Office of Public Safety Support Services.
"Basically, our role is to help prepare the jurisdiction to deal with an emergency, whether natural or man-made," Martin said.
The 59-year-old Finksburg resident wants to travel but also plans to make his services available to the county, he said.
Before his Carroll job, Martin was a firefighter, administrator and fire marshal with Baltimore's fire department for 32 years.
William R. Hall Jr. of Sykesville replaces Martin as coordinator, said Scott Campbell, director of the Office of Public Safety Support Services.
Hall, who was the county's emergency management planner and is a retired Baltimore firefighter, will assume all the coordinator's duties, including working with the volunteer association, assisting with staffing the Emergency Operations Center during emergencies, and supporting field efforts, Campbell said.
The emergency management planner position will be advertised, Campbell said. It deals with all planning aspects of emergency initiatives and works with other regional jurisdictions.
