Colleyville, Texas City Hall
Outdoor Warning System
The Colleyville Outdoor Warning System consists of 8 sirens placed in a broad geographical cross-section of the city. The System provides alert coverage in densely populated residential, business and public institution areas, so as to alert the greatest number of citizens.  In fact, Colleyville’s Outdoor Warning System, together with neighboring cities' sirens, provides full coverage of the city.  All 8 sirens were installed on city-owned or maintained properties, rather than private property, to minimize impacts on neighborhood aesthetics.  The 8 sirens cost the city a total of $132, 769.

This outdoor warning system is a part of the city’s commitment to a comprehensive and coordinated effort to mitigate the effects of a hazard, prepare for necessary measures that will preserve life and minimize damage and respond to hazard or disaster events by providing the necessary assistance and emergency support functions.  In order for the Siren System to accomplish its goal, it is imperative that all citizens know what to do when the sirens sound.

Remember:  The emergency alert siren is for OUTDOOR NOTIFICATION.  Do not expect it to notify you of emergency conditions while you are indoors.
When the warning sirens are activated citizens should:

  • Go inside right away.
  • Turn on a radio or television to hear the latest weather or emergency information.
  • Take shelter in an inside room or basement if appropriate.
  • Keep in mind,
    • The sirens are not a signal to evacuate. Your area may not be affected by an emergency, or you may be asked simply to remain indoors for a period of time. You will be given specific instructions about whether to stay inside, leave the area or take other protective action.
    • Do NOT call 9-1-1 when you hear the siren.  The area media, National Weather Service, or Emergency Alert System will provide updated information.  Citizens should use their televisions or radios to get these updates.
