1. How does the system work?

Alert Southlake is powered by Everbridge®, a web-based application that uses mapping technology to provide notifications, and/or written text or email notifications to people in a precisely targeted geographic area. Trained emergency officials can essentially “draw” an area on a map, record an emergency message, and launch the alert to those in the affected area.

While the system is able to rapidly contact thousands of residents in one launch procedure, there may be limitations. It is always important to remember that technology can sometimes fail.  No single alert or tool will provide enough warning to all residents in all situations. This system is only one part of a comprehensive emergency warning program and should not be your sole means of emergency notifications.

2. Who receives notifications?

The City of Southlake annually updates mobile phone numbers that are billed to a Southlake address and publicly available landline phone numbers that include residential and business numbers, registered to a Southlake address. Landline phone numbers that are not publically available or mobile phone numbers that are not billed to a Southlake address must be manually added to our system. Preferences can be changed at any time by the user.

3. Why did you automatically add mobile phone numbers?

Due to the enormous resident feedback from the February 2021 winter storm, the City of Southlake worked with our vendor, Everbridge, to automatically add all mobile phone numbers billed to a Southlake address to our emergency notification system, Alert Southlake. 

The technology of mobile service (cell phones) has taken over the world and is highly relied upon as 64.9% of children and 55.2% of adults have wireless service only. With our opt-in campaigns, we were only reaching about 25-40% of our resident population. With this new resident connection update, we will be able to communicate emergency information effectively and efficiently with 60% or more of Southlake residents with the push of a button.

5. Will my contact information be shared with others?

No. The information that you provide will be used only for Alert Southlake notification purposes. We will not give or sell your contact or location information to any vendor or other organization.

6. I am hearing impaired and I have a TTY/TTD device. Can I use the system?

Yes. You can register the phone number associated with your TTY device via the online portal: https://member.everbridge.net/892807736726279/login.

7. Can I update notification preferences?

All Alert Southlake accounts can update preferences, such as quiet hours, to not receive notifications during specific times. Previously input user preferences will be saved from year to year. Before opting out of all notifications, it is recommended to modify the account to specific preferences. If we can reach you through an alert, we can notify you of important emergency information. 

You can update your account settings at any time by going to https://member.everbridge.net/892807736726279/login. After setting up an account or logging in, you can update your preferences for text messages, phone calls, and emails, as well as phone numbers and addresses, or simply opt out. If you do not remember your username or password, please contact the Office of Emergency Management at 817-748-8903.
