City of San Diego Emergency Notification System
Background Information
During the 2007 Wildfires, the City of San Diego and the County of San Diego both employed emergency notification applications (Reverse 911® and Alert San Diego) to assist in the safe evacuation of over 515,000 residents.
To build upon this success and further improve public safety and welfare, the City of San Diego has added Alert San Diego to its own Emergency Notification System. Alert San Diego is a telephone based application similar in function to Reverse 911®, but with certain technical differences. Having both applications available for use during an emergency will provide the City with greater redundancy and notification capability.
The resulting Emergency Notification System allows the City to rapidly send telephone notifications to residents and businesses in an affected area in the event of an emergency. An operator using the system can identify the affected neighborhood or region of the city and record a message that describes the situation. The system will automatically call listed and unlisted telephone numbers within the affected area and deliver the recorded message. If phone lines are busy, the system will attempt to redial those telephone numbers to make contact. If an answering machine picks up the call, the emergency message will be left on the machine.
While every attempt will be made to contact residents in response to an emergency, there are factors that impact completion of calls. Those include loss of electrical power, call volume in the area reducing available lines, busy connections, hang ups, caller ID blocking, etc. Residents should not wait for an emergency call. If you are concerned about your safety and welfare, please leave the area and monitor local radio stations for further information (KOGO AM/600 and KLSD AM/1360).
