Los Angeles County officials have announced that an emergency mass notification system is in place to contact county residents and businesses via recorded phone messages, text messages or email messages in the event of critical situations.

The system called “Alert LA County” allows the county’s Emergency Operations Center to provide residents and businesses with necessary information during emergencies, such as evacuation alerts.

The system utilizes telephone companies’ 911 databases, contacting land-line telephonenumbers whether listed or unlisted. If the call is picked up by an answering machine, the system will leave a recorded message, If the number dialed is busy or does not answer, the system will redial the number in an attempt to deliver the message.

The Alert LA County system uses 911 databases, with land-line numbers automatically stored in the system.

To receive notifications for cellular, voice over IP numbers and email addresses, residents and businesses can register at: http://portal.lacounty.gov/wps/portal/alertla.

The alert system uses geo mapping where each telephone number and/or email address can only be associated with one street address in the system. Each telephone number and email address will be contacted when the street address it is associated with is impacted by a disaster or emergency.

Residents and businesses are also encouraged to monitor the Los Angeles County Department of Beaches and Harbors social media sites, Facebook and Twitter by accessingFacebook.com/LACDBH and Twitter.com/lacdbh for real-time updates along the county beaches and Marina del Rey.
