The City of Richardson's public warning system is much more than a system of outdoor sirens. The sirens are important, but they are just one component of a much larger system. There is a great deal of communication and coordination taking place behind the scenes before the sirens are ever sounded. The City of Richardson's ability to provide warnings is a result of partnerships with the National Weather Service, local emergency response agencies and 9-1-1 Center staff as well volunteers who are trained as volunteer storm spotters and amateur radio operators
. These groups all work together to make up an integrated system of hazard detection, consequence prediction, and warning dissemination.
The City of Richardson takes an "all-hazards" approach to public warning. This means that we use the same decision-making structure and alerting methods, regardless of the threat. Severe weather is far and away our most common threat, but it is not the only one we face. A hazardous material release, for example, could cause a threat to public safety. An incident of this type may necessitate activation of any one of a number of components of the system, including outdoor warning sirens.
