Emergency Operations Center

A central component of the Emergency Services Division is the County's Emergency Operations Center (EOC). The EOC becomes the seat of county government and the single coordinating and warning point for any large-scale emergency in Washtenaw County. The EOC is normally staffed during business hours, but it remains staffed for approaching severe weather and it can quickly be activated with numerous government officials for any emergency twenty-four hours a day. The EOC can operate for an extended period, as needed.

Emergency Communications Center

The Emergency Communications Center (ECC) is the technology arm of the EOC. Without solid communications during a crisis, it would be impossible to provide assistance to local governments and incident managers in the field, and very difficult to provide the public with official information. The EOC also functions as a critical link with state and federal agencies during a catastrophic event.

The ECC and EOC are connected to an automatically switching 600 Kilowatt emergency generator and a 20 KVA UPS for surge protection and continuous operation.


Some of the systems available in the ECC are:

  • Advanced weather station including lightning detection
  • Amateur radios (multiple bands)
  • Commercial facility emergency plans and maps
  • Emergency Alert System encoder/decoder
  • Fax machines
  • Geographical Information Systems mapping and display
  • Group text messaging server
  • Hazardous materials response databases
  • Internet
  • National Weather Service NOAAport Doppler weather radar, infrared satellite imagery and teletype
  • Primary and backup telephone system
  • Quick-Call and community siren warning system
  • Radio communications consoles with capabilities on all public safety frequencies
  • Several modes of secure satellite communications
