COLUMBIA — The City of Columbia has completed installation and testing of a new citywide public safety siren system, marking the most significant upgrade to the city's emergency alert infrastructure in recent memory. The 12-siren network was successfully tested on Monday, May 11, and is now operational across the city.
The $420,000 project was funded entirely through a Community Development Block Grant (CDBG) Imminent Threat Program and completed in partnership with the South Central Tennessee Development District — meaning Columbia taxpayers did not foot the bill directly. The system includes three electric sirens capable of both audible tones and voice messaging, and nine mechanical sirens engineered to push strong, far-reaching warning signals across neighborhoods. Together, they form what city officials describe as a layered outdoor alerting network.
Mayor Chaz Molder said the investment reflects the city's ongoing commitment to resident safety. City Manager Tony Massey echoed that the modern, reliable system will strengthen the city's ability to deliver timely warnings during severe weather and other emergencies. The sirens are activated only when the National Weather Service issues a tornado warning — meaning a tornado has been sighted or confirmed by radar — and only for the specific portions of the city under threat.
Siren locations were chosen to maximize coverage across Columbia's geography, from fire stations on Trotwood Avenue and Nashville Highway to elevated positions at Reservoir Hill and Golston Hill. Additional units cover the East and West pump stations, Fairview and Ridley parks, and residential areas near Drone Way and East Burt Drive. Residents who live near those corridors may have heard the test Monday morning.
City officials are reminding residents that outdoor warning sirens are designed to alert people who are outside — they may not be heard indoors, especially during a storm when wind and rain can mask the sound. For that reason, Columbia urges everyone to use multiple alerting methods. The city's free Hyper-Reach emergency notification system sends alerts directly to mobile devices or landlines and is integrated with the National Weather Service and the federal IPAWS network.
Residents can sign up for Hyper-Reach by calling or texting "Alert" to 931-286-7771, or by registering online. Future siren test dates will be announced in advance on the city's website at ColumbiaTN.gov and on official city social media channels. Tornado season in Middle Tennessee is no time to be caught off guard — and now, Columbia is a little better prepared.
