Our Mission Statement

The County Office of Emergency Services is committed to serving the public before, during and after times of emergency by promoting effective coordination between agencies, and encouraging preparedness of the public and organizations involved in emergency response.

On Tuesday and Wednesday October 14 and 15, 2014, the Early Warning System sirens located in the Diablo Canyon Emergency Planning Zone (EPZ) will undergo regularly scheduled quarterly low volume growl tests. Each of the 131 sirens throughout the EPZ will be tested individually for a period of a few seconds. This is only a test and no action is requested or required on the part of the public.  

 PG&E Diablo Canyon is continuing work on an Early Warning System siren upgrade project in coordination with the County of San Luis Obispo. The control system components of each siren within the Emergency Planning Zone are being upgraded. The siren system will remain operational throughout the project and backup route alerting will be established for any siren that is temporarily out of service. No full volume test of the siren system will occur during this project. However, short growl tests of each siren may be audible to the public. Visit our facebook page to see video of a siren growl test in action.
