Public Safety agencies throughout San Mateo County use Genasys (formerly known as Zonehaven) to communicate areas that are being evacuated due to fire or other emergencies. Download the Genasys Protect app and identify your zone number and be familiar with how to access the mapping program within the app so you can track evacuation zones as evacuations are ordered. Genasys / Zonehaven isn’t an alert and warning system, rather it can be a source of additional information that can help provide direction in times of emergency.  One of its greatest uses is letting evacuated individuals know when it is safe to return.   The Genasys Protect app will notify users of changes to their current subscribed zone as well as the zone you are in at the time of any status change.
