The Community Warning System in Contra Costa County has been upgraded to support “Opt-in” alerts to cellular phones. You may now receive notification via your cell phone any time an alert is issued for a shelter-in-place, public health, hazardous material, or other emergency in your area. You may even choose a zip code for which you would like to receive an alert.
There is no charge from the County for this service. However, your cell phone service provider may charge you in accordance with your individual plan.
