Museum Fire Flood Area Siren System Installed In Flagstaff And Will Be Tested Friday

A siren alert system has been installed, and will be tested at 2 p.m. Friday. The system will help warn residents of flooding that is imminent in neighborhoods downstream of the Museum Fire burn scar. Four elevated high power speaker arrays were installed throughout the Grandview Homes and Sunnyside neighborhoods throughout May. The sirens will emit alarm sounds and voice messages when rain thresholds are triggered within the Museum Fire burn scar. When residents receive the Emergency Notification Alert text message, or hear the sirens, they should immediately follow all safety instructions. To sign up to get alerts, log onto coconino.az.gov/ready.

The following specific protocol will be used during a rain event in the area:

Threshold 1

Activated by 0.25 inches of rainfall in 15 minutes as measured by rain gauges throughout the Museum Fire burn scar.

The Flood Director will alert the Emergency Operations Center, City and District officials and activate personnel to monitor drainages and water flows. No emergency notification alerts will be sent, and the siren alerting system will not be activated.

Threshold 2

Activated by 0.40 inches of rainfall in 15 minutes as measured by rain gauges throughout the Museum Fire burn scar.

An Emergency Notification Alert will be issued only for the Mt. Elden Estates neighborhood. A text message with the alert will be sent to cell phones registered to addresses in the area through the Emergency Notifications database. The siren alerting system will be activated, and the alert will also be posted to City and District social media channels.

Threshold 3

Activated by 0.75 inches of rainfall in 15 minutes as measured by rain gauges throughout the Museum Fire burn scar.

An Emergency Notification Alert will be issued for the Mt Elden Estates, Paradise, Grandview Homes and Sunnyside neighborhoods. A text message with the alert will be sent to cell phones registered to addresses in these areas through the Emergency Notifications database. The siren alerting system will be activated, and the alert will also be posted to City and District social media channels.
