Sierra Madre Issues a Yellow Flag Alert

The City of Sierra Madre has issued a Yellow Flag Alert today. The County of Los Angeles Public Works Department has issued a Phase 1 Mudflow Forecast. A Phase 1 indicates that small isolated debris and mudflows are possible at specific locations.

Streets may be flooded or blocked by debris. Woodland Drive, Skyland Drive, and other streets may be closed due to blockage. Should debris flows occur overnight, crews will begin clearing the following morning.

Parking restrictions are now in effect in the Upper and Lower Canyon during Yellow or Red Flag alerts. Vehicles parked on the streets may be towed at owner’s expense.

The affected streets are: Mount Wilson Trail, Churchill Rd., Skyland Dr., Fern Glen, Fern Dr., Idlehour Ln., Canyon Crest Dr., Orange Dr., Woodland Dr., Brookside Lane (upper, middle, and lower segments), Sunnyside Lane, Sturtevant Dr., and Yucca Trail. Overnight parking restrictions through the rest of the city are lifted during Yellow or Red Flag Alerts.

The City Public Works Department may determine that Upper Brookside Lane and the very northern portion of Woodland Drive will be closed and a temporary debris wall will be erected.

Residents in the affected areas are urged to be “set” to leave at a moment’s notice and may choose to voluntarily evacuate. In the event the City receives a Phase 2 or Phase 3 alert from the County, a Red Flag Alert will be issued that will most likely include mandatory evacuation orders. Evacuated residents will not be allowed to return into an evacuation area until the order is lifted.
