IS there a plan in place to place a warning siren in or near the Cobb Hill subdivison soon? After the last several violent storms where the sirens city wide went off (as I understand) we couldnt hear them at all and our neighbors all agree they didnt hear them either but just faintly when you stepped outside when it wasnt raining. For the safety of the residents in this large subdivison what steps can be taken to have a warning siren put up in or near our neighborhood?
Thank you

Mr. Grandell,
The outdoor warning sirens are designed to warn those citizens who are outside during a potentially hazardous condition including severe weather. When inside a home or business it is recommended to have a weather radio or tune to local TV or radio stations for updates and warnings. A NOAA all hazards radio (weather radio) may be purchased to receive announcements directly from the National Weather Service.

While being able to hear the sirens outdoors achieves the desired intent, we recognize that coverage could be better in some areas of Frisco. We are currently working with a consultant to update our Outdoor Warning Siren network and to review the planned siren placement that will provide coverage for what will become all of Frisco when fully developed. When that is completed, in the near future, sirens will be added to the currently developed areas of Frisco which may benefit from enhanced coverage. In reviewing your location and the current siren placement, I am sure sirens will be added that will enhance the coverage in your neighborhood.

To get more information on severe weather awareness, please visit the Frisco Fire Department website at

There was a piece on one of the local news stations recently about some cities experimenting with a system that makes phone calls to homes that are in the direct path of violent storms. Is Frisco looking at doing anything like this?

Mr. Fritchie,

Chief Siebert and others keep abreast of this type of technology. For the past few years, we have used a version of a “Reverse 911” system successfully to notify citizens of critical information that is important but does not have imminent implications.

About two years ago, during the summer, a water main break at the Lake Lavon delivery source created what could have been a devastating set of circumstances. Water levels would have become critical had the Region not been able dramatically reduce its water usage in a few hours. We were able to deliver this message by phone, using Frisco’s system, in about 3 hours to our entire city. Frisco actually delivered to greater numbers faster than any entity affected by that potential crisis.

More recently, our Police Department has used the system to alert neighborhoods of recommended actions for crime prevention based current trends. These, I believe, are examples of the best use of this type of system.

Over a year ago, vendors began to pursue sales of similar technology for warnings that were of an immediate nature. We believed that the capability of these systems would be limited in their ability to notify, in a timely enough fashion, our citizens due to the system’s inability to make thousands of calls very quickly. Recently there have also been news stories about people receiving phone calls over an hour after the tornado warning was over. I believe this is a direct result of these systems shortcomings.

Your interest, comments, and suggestions are welcome and appreciated at any time. We will continue to monitor technological advances that may improve upon our ability to provide enhanced warnings and hope you do likewise.
