How It Works

If there is a safety hazard or concern in your area, you will get a notification on whichever phone number or email you entered when you signed up.

Once you confirm that you have received the message, the system will stop trying to reach you. If you don’t confirm, the system will continue to try to reach you using all the contact numbers and emails that you provided. 

You can update your information at any time. If you would like to stop receiving notifications, you can opt-out by removing your profile from the system.
