Emergency Management

The purpose of this section is to inform Greenfield residents about procedures that are followed when there is an emergency that affects the entire community. Emergency Management is the city agency responsible for all aspects of local emergencies, including preparing, response, recovery, and mitigation.

Phases of Emergency Management

The process of emergency management involves 4 phases: mitigation, preparedness, response, and recovery.


Mitigation efforts attempt to prevent hazards from developing into disasters altogether, or to reduce the effects of disasters when they occur. The mitigation phase differs from the other phases because it focuses on long-term measures for reducing or eliminating risk.


In the preparedness phase, emergency managers develop plans of action for when the disaster strikes. Common preparedness measures include:
  • Communication plans with easily understandable terminology and methods
  • Proper maintenance and training of emergency services, including mass human resources such as community emergency response teams
  • Development and exercise of emergency population warning methods combined with emergency shelters and evacuation plans
  • Stockpiling, inventory, and maintain disaster supplies and equipment
  • Developing organizations of trained volunteers among civilian populations


The response phase includes the mobilization of the necessary emergency services and first responders in the disaster area. This is likely to include a first wave of core emergency services, such as firefighters, police and ambulance crews.


The aim of the recovery phase is to restore the affected area to its previous state. It differs from the response phase in its focus. Recovery efforts are concerned with issues and decisions that must be made after immediate needs are addressed and are primarily concerned with actions that involve rebuilding destroyed property, re-employment, and the repair of other essential infrastructure.

Implementation of Emergency Management

In the event of a local disaster or emergency, Greenfield Emergency Management will work collaboratively with Milwaukee County Emergency Management. The city may also need to coordinate with Wisconsin Emergency Management and the Federal Emergency Management Agency.
