The Gwinnett County Office of Emergency Management is a unit of the Gwinnett County Police Department that handles a variety of tasks involving planning for emergencies and disasters, responding to incidents as a coordinating agency, directing mitigation against hazards, and assisting Gwinnett County Government and its residents in recovery after an incident.

The Office of Emergency Management works very closely with all Gwinnett County departments and private/nonprofit partners to accomplish these goals.

To administer a community wide comprehensive emergency management program in partnership with all departments, agencies, operating units, administration and neighboring jurisdictions to save lives, protect property and safeguard the environment.

The Gwinnett County Emergency Operations Center (EOC) is managed and maintained by the Gwinnett County Office of Emergency Management. An EOC is a central location from which local governments can provide interagency coordination and executive decision making in support of incident response and recovery operations. The purpose of the EOC is to provide a centralized location where public safety, emergency response, and support agencies coordinate planning, preparedness, and response activities.

The EOC does not command or control on-scene response efforts, but does carry out the coordination functions through:

1. Collecting, evaluating, and disseminating incident information
2. Analyzing jurisdictional impacts and setting priority actions
3. Managing requests, procurement, and use of resources 

The decisions made through the EOC are designed to be broad in scope and offer general guidance on priorities. Information is disseminated through the EOC manager and tactical decisions are coordinated from field response personnel.
