Severe Weather Sirens

Warning Sirens

The Village of Chicago Ridge's Emergency Warning System (EWS) is an outdoor, all-hazards siren system that is used to warn the general population of a potential danger in a short amount of time and to notify them that the emergency has passed.

Chicago Ridge currently has 2 sirens located strategically at the Firehouse located at 10063 S. Virgina Avenue and 10658 S. Lombard to ensure total citywide coverage. The EWS may be activated by individual siren or village wide.

What Do the Sirens Mean?
The system uses three siren tones. When they are activated during an emergency, the sirens will be activated for 3 minutes.

Please note that the Village does perform a monthly siren test to ensure all sirens are functioning. The entire system is tested for aproximatly 2 minutes at 10:00am on the first Tuesday of every month. The EMA may also perfom a "growl" test perodically to test the siren operation throughout the year or during maintenance of the siren.
