To REMOVE  yourself from notification


Who should sign up? Anyone living within the City of Longmont limits who no longer have a land line in their home (a land line, main line or fixed-line is a telephone line which travels through a metal wire or optical fiber and does not require power for it to work). If you own additional communication devices i.e. cell phones, VoIP(voice over Internet protocol), email, etc. you will want to sign up for this service as it provides a number of additional ways in which emergency information can be disseminated quickly.

This is available in other BOULDER COUNTY cities/towns/unincorporated areas by going to your local municipal/town/county website and checking for the link on their website. If you cannot find it on their website, contact YOUR LOCAL GOVERNMENT OFFICE. You may also get the information statewide at

When will the emergency notification system be used? The system will be used to notify residents about imminent threats to health and safety such as the need to evacuate due to a wildfire, hazardous spills or other emergencies. It may also be used in situations where a child or adult is missing who is in need of medical attention. The alert will originate from  NOTE: Longmont Public Safety has added SMARTWeather Alerting system to our existing Everybridge Emergency Notification System. This leverages Weather Decision Technology (WDT) to provide location-specific severe weather alerts from the National Weather Service. As of today, 12/14/17, anyone signed up for Longmont's Everbridge system will receive notification AUTOMATICALLY for flash flood and tornado warnings. No action is required.

Is there a fee to use the service? No. The service is free to residents of Boulder County. Those who sign up to be notified via text messages and email will be responsible for any data charges or fees associated with receiving email or text messages charged by their cell phone service provider.

What if my phone number or emails address changes? If your cell phone, work phone or email address changes, you are responsible for accessing this website, logging back into your account that you created and updating the information.

Will my contact information be shared with others? No. The information that you provide will be used for emergency notification purposes only. It will not be provided to any vendor or organization or be used for any other purpose.

Will I be guaranteed to receive the notification? We cannot monitor the current or future accuracy of the information provided by participants in this program. It is the sole responsibility of participants to keep any information provided current and accurate. We do not assume legal responsibility for inaccurate information or technical difficulties that may result in notification failures.

Do I Need to Enter an Actual Address? Yes. The system is based on geographical boundaries and will not accept post office box addresses.

If I have a "blocked" phone will this impact receiving emergency messages? You will not receive the notification call with a blocked telephone line. Solicitor blocking services will also impact notification. You must add (303) 651-8501 to your "trusted numbers" list to receive messages.

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 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.

If you have further questions, please email or call (303)651-8566. If no one immediately answers this phone line, please leave a message and someone will return your call.
