Emergency Notification Alerts

ArapAlert_button_RevisedArapahoe, Jefferson, and Douglas counties have launched state-of-the-art emergency notification systems to alert citizens about emergencies. The emergency notification system enables the county to provide essential information quickly in a variety of situations, such as fires, floods, evacuation of buildings or neighborhoods, and other emergencies.

How Emergency Alerts Work

When the county issues a message about a potential safety hazard or concern, messages will be sent to all standard voice and text communication devices (land line, mobile, email, instant messaging, text messaging, PDA, alpha or numeric pager, etc.) that you have registered in the system. The system will continue trying to contact you on these devices until it receives a confirmation from you that the message has been received.

Please note that this system will not be used for weather alerts because the timeliness or accuracy of such alerts cannot be guaranteed. There are a variety of other media outlets (TV and radio stations, and weather-related websites and alerts) that can provide this service in a more timely manner.

How to Sign Up for Emergency Alerts

Residents and businesses with land line phones are already listed in Arapahoe County's 9-1-1 database, and are therefore automatically included in the notification system. You may sign up to register additional mobile devices. Your information will be kept strictly confidential.
