CAS The Cupertino Alert System (CAS) allows the City to rapidly notify residents and businesses by telephone, e-mail, Short Message Service (SMS), and fax in the event of an emergency. Should an emergency occur, city personnel could notify residents in a matter of minutes. CAS can call all telephone numbers and e-mail addresses listed within the system.

In addition to the CAS notifications, the City Channel, Ch. 26 on Comcast Cable or Ch. 99 on AT&T, Radio Cupertino 1670 AM, FacebookTwitter and the City of Cupertino website, will have information regarding the situation.


Opt-In or Out

Opt-in or opt-out is the process of subscribing to or unsubscribing from information that is sent to residents through electronic means. When you opt-in for notification alerts, you are allowing the system to send urgent notifications to your listed contact information (e-mail addresses, home, work and cell numbers, fax, and SMS address).

When you opt-in, you are required to provide your name, address, city, state, zip code and at least one contact number. Your address is used to determine your geographic location within the city. If your location is within the specified area, CAS will contact you through the contact information you listed with that street address.

Opt-out is the process of unsubscribing from CAS which will result in no notifications from the system.
