The City of New Braunfels will conduct routine testing of its Outdoor Warning Siren System on Tuesday, August 5, 2025, at approximately 12pm.
New Braunfels City Council approved the purchase of the sirens in late 2010 and they were installed in early 2011. There are a total of eight sirens that sit atop 40-foot galvanized poles along the Comal River, Guadalupe River, and Dry Comal Creek. Those sirens are located at:
- River Acres Park (Fair Lane and River Acres)
- Gruene River Crossing (Ervendberg Avenue and Gruene Road)
- Fire Station 3 (Gruene Harley-Davidson Parking Lot)
- Torrey Park (East Torrey Street and Gruene Road)
- Prince Solms Park (Tube Chute)
- Boy Scout Hut (East Coll Street and South Market Avenue)
- HEB Soccer Complex (Live Oak Avenue)
- Camp Comal (End of Kuehler Avenue)
The sirens are strategically placed to alert those in flood-prone areas or areas that may be affected by rising river levels. That includes those who have homes in those areas as well as campgrounds, RV parks, and businesses. Each siren is loud enough to be heard at least a mile away, and four of the sirens are also equipped with voice-announcement capabilities that are audible within half a mile. In the case of potential flooding, the sirens are manually enacted by Fire, Police, and Emergency Management personnel based on river flow data and information from the National Weather Service.
The siren system, which can be used for a variety of emergencies beyond floods (like fires, tornadoes, or hazardous material spills) is part of a multi-tiered alert system that also includes door-to-door notifications by first responders, social media alerts, website alerts, as well as text and email alerts. Residents can also register their mobile phones to receive emergency notifications from the city’s Emergency Notification System (ENS), commonly referred to as Reverse 911. Residents are encouraged to register their mobile phones, which allows first responders to send targeted alerts by phone, text message, or email. To register, visit http://www.newbraunfels.gov/ENS.
The City of New Braunfels Outdoor Warning Siren System is routinely tested the first Tuesday of each month at approximately 12pm, and, again, the next scheduled test of that system is scheduled for approximately 12pm on Tuesday, August 5th, 2025.
