Brookhaven Mayor John Ernst will hold a town hall on Thursday, Sept. 20, that will include a presentation on the city’s new Brookhaven Alert system. The town hall will be at 6 p.m. at City Hall, 4362 Peachtree Road.

Brookhaven Alert, powered by Smart911, is a free service available to all residents. People can sign up to receive notifications sent from state and local authorities on weather, traffic and other emergencies.

Alerts can be received via email, text or voice message on their cell phones. To sign up, visit www.brookhavenga.gov/brookhavenalert or by downloading the Smart911 app in their mobile app store.

When residents sign up for Brookhaven Alert, they will also have the opportunity to input their information and notification preferences today on the secure Smart911 online system. Their information will immediately be available to 911 in the event of an emergency.
