Changes are coming to Eagle County’s alert system. As of Feb. 1, most mobile alerts will require an app from EverBridge, the system’s vendor. (Daily file photo) You may have read that Eagle County’s alert system is changing as of Feb. 1. Here’s why: In a recent presentation to the Vail Town Council, Vail Public Safety Communications Center Director Marc Wentworth said the main issue is money. The Eagle County E911 Authority Board since 2014 has contracted with EverBridge for alert services. The cost is roughly $28,000 per year. Wentworth said EverBridge is changing its billing model. That means the old system of sending out text messages and emails will have to change. In fact, the cost of sending text messages could roughly triple unless changes are made.
