Emergency Management


Many of the cities and townships in Ottawa County have recently updated their emergency siren system. New technology has enabled Ottawa County Central Dispatch (OCCD) to activate the sirens for a countywide warning as well as a warning just for the north or south sections of the county. The local communities still control their own sirens, which gives them the ability to sound them for local emergencies.

The communities in Ottawa County with sirens are:siren

  • Allendale Charter Township
  • Blendon Township
  • Chester Township
  • Coopersville City
  • Crockery Township
  • Ferrysburg City

  • Grand Haven City
  • Grand Haven Charter Township
  • Grand Valley State University
  • Holland City
  • Hudsonville City
  • Robinson Township
  • Spring Lake Village
  • Spring Lake Township
  • Zeeland City

Note: The sirens are tested at noon on the first Friday of each month from March through November.

The purpose of the sirens is to notify residents of any emergency situation. The sirens will sound for the following conditions:
