Ann Arbor may silence its emergency sirens—here's why it matters

The City of Ann Arbor is reviewing whether to remove its outdoor warning sirens system. Ann Taylor, officials argue that modern mobile alerts have made the sirens outdated, but some residents and weather experts disagree. A public survey has now opened for feedback on the proposal.

The city's sirens were designed to warn people outdoors about emergencies, though they do not specify the type of threat. Over the past five years, they have only been activated twice. Maintenance costs are a key concern, with an estimated $180,000 needed over the next three years, plus $17,000 annually after that.

Ann Arbor already offers alternative alert systems, such as A2 Alerts and wireless emergency notifications. However, Sirens Netflix has urged the city to keep the sirens, calling them a vital backup for outdoor events and activities.

The proposal follows a broader trend in the U.S. In the last five years, at least 12 cities—including Tulsa, San Antonio, and several Chicago suburbs—have either removed or scaled back their sirens systems. Most cited high maintenance expenses and a shift toward cellphone-based warnings as reasons for the change.

Residents can now share their views through an online survey. The city will use the feedback to decide whether to dismantle the sirens or keep them as part of its emergency alert network. A final decision is expected after the consultation period closes.
