Emergency Notification



Arapahoe, Jefferson, and Douglas, the three counties that serve the City of Littleton, utilize a state-of-the-art emergency notification system to alert citizens about emergencies. The emergency notification system enables the city 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 city 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 web sites 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. If you would like to register additional voice and text devices, please click on the appropriate link below to go to the signup page for your county. All information you provide will be kept strictly confidential.

Frequently Asked Questions

Will my information be sold or distributed?
No. All of the information you enter will feed directly into the Target Notification systems secure database. This information can only be accessed by system administrators and the data will never be sold or distributed to third parties.

When will I receive phone calls?
You will receive phone calls when the system is activated and your address is within the geographic area chosen to receive the notification message. The system will only be activated for emergency purposes.

What do I do if I move?
If you move after you have entered your information into the website you will need to go back into the website and re-enter your information with your new address.

Can I add my landline telephone number?
Yes. You can enter your landline phone number into the Opt-In website. If your landline phone number is already in the database, the data you enter into the site will NOT overwrite the existing information for your landline telephone number. If your landline phone number is not already in the database, then the new information will be entered into the database.

Will I be solicited in any way at the phone number that I enter?
No. You will only receive phone calls when the system is activated and your address is within the geographic notification area chosen. The system will only be activated for emergency purposes.

If I am in a location that is different than the address that I enter into the website for my wireless phone, will I still be contacted if an emergency affects the address entered?
Yes. No matter where you are physically located, you will only receive calls for emergencies that affect the address entered into the website. So if you are on vacation in a different state you will still receive a phone call if the address you entered is affected by an emergency.

Are there any fees associated with target notification?
There are no fees to create an account with target notification, regardless of the number of phones and VOIPs that you enter. However, the system’s calls to cell phones will be deducted from your cell phone plan's minutes, just as any other incoming call. The cost of the service is provided by fees paid to the different county authorities.

Is the target notification system able to assist individuals that are deaf or hard of hearing?
The notification system does have TTD capabilities to assist those individuals.

Can I select the types of emergency situations that I want to be include in the target notification and exclude others (i.e. wildland evacuations but not Amber Alerts)?
No. Numbers registered with target notification will receive all messages impacting their area.

If I have a "blocked" phone, will this impact target notification?
Yes. You will not receive the notification call with a blocked telephone line.

How to Stop Receiving Alerts
If you decide that you no longer wish to receive emergency alerts, you can opt out of the city's emergency notification system at any time. You must provide information on all communication devices that you originally registered into the system.

If you opt out, your home or business phone will not be contacted, as this information will be deleted from the system. However, every quarter, County 9-1-1 land line information is updated; therefore, the associated telephone numbers will be refreshed within the system. You will need to repeat the opt-out procedure for these numbers.
