This is an important message from the County of Orange. On Wednesday, October 19, the Community Alert Siren System for the San Onofre Nuclear Generating Station will be tested several times between 10am and noon. We are notifying residents in Ladera Ranch due to the proximity to one of the sirens. This is only a test, and no action is required. Please do not call 911 unless you have an actual emergency.

During an emergency, the sirens alert residents to turn on the television or radio and listen for important emergency information.
