Sign up for alerts

Genasys Protect (formerly Zonehaven)

Depending on the size and scale of a disaster, we may use Genasys Protect (formerly Zonehaven) to share evacuation and traffic information. We will use it to post location and zone specific information.

Genasys Protect is not an alert system – you need to check the website for status updates.

City of Piedmont website

During emergencies, we will keep the City of Piedmont’s website homepage up-to-date with important local information.

X (formerly Twitter)

Follow these accounts for updates during emergencies:


During emergencies we will post updates on the City of Piedmont’s Facebook page.

Watch out for misinformation

In a disaster, misinformation can spread quickly, especially on social media and online forums. Well-intentioned people can inadvertently share rumors that do more harm than good.

Before you share or act on information, check the official sources listed on this page to verify it.
