Hi-Lo Audible Warning Sound

The Hi-Lo audible warning sound is an alternating high and low tone, which you may hear during an evacuation. Play the video below for a demonstration. If you hear Hi-Lo audible warning sound, it means there is a mandatory Evacuation Order. Voice instructions over the emergency vehicle’s loudspeaker will follow. In California, the Hi-Lo audible warning sound is reserved only for evacuations.

When you hear the Hi-Lo, it’s time to go!

Don’t Wait to Evacuate

You could be notified of an evacuation by a knock at your door by public safety officials – but only when time and resources allow.  

Because all emergencies are different, and because no method of notification is entirely fail-safe, be prepared to evacuate in response to any of the notification methods described above. Even if you have not yet received any notification to evacuate, LEAVE IMMEDIATELY if you feel it is unsafe to stay. Don't wait to evacuate!

Genasys Protect

The City of Fremont uses a software called Genasys Protect (formerly Zonehaven) to share real-time information during evacuations. This system provides shared awareness among public safety officials, supporting services, and the public.

Know Your Zone

Fremont is divided into more than 100 pre-planned evacuation zones. Find your zone on the map below.

During an evacuation, designated zone(s) will change color according to the Evacuation Statuses above. You can click the zone for more information about the evacuation.

Forgot your zone? That’s okay. When an Evacuation Order is issued, you can expect to be notified by one or more of the methods described under “Know When It’s Time to Go”.

Preparedness Tips for Everyone

During an Emergency:

• Leave the area immediately if there is an Evacuation Order.
• Don’t wait for an Evacuation Order if you feel unsafe. Leave early if you are unsure. Conditions can change quickly. Stay alert and keep calm.
• Carry your wallet, keys, and cell phone with you.
• Once you are safely out of the area under evacuation, check City of Fremont social for updates and tune in to KCBS 740 AM, KQED 88.5 FM, or other news sources.
• Stay with friends or relatives, or at other accommodations, if you can. The City may set up shelter for evacuees, but this may take several hours.
• The City may establish a Temporary Evacuation Point where evacuees can assemble and receive information. This provides a good place for information – and to remain temporarily until the Evacuation Order is lifted or additional temporary services become available. A Temporary Evacuation Point is typically a parking lot or other public facility, established shortly following the evacuation.

Before an Emergency:

• Gather emergency supplies and prepare a Go Kit. 
• Make a plan.
• Get connected. Sign up for AC Alert and Nixle.
