The alert affects roughly 25 homes along Mel Canyon Road between Brookridge and Fish Canyon roads. Parking restrictions will be in place along that stretch, as well as on Deerlane Drive between Mel Canyon Road and Greenbank Avenue.

Residents in the affected Duarte area were also instructed to remove all trash bins from the street, and place them on their driveways closer to their homes, where they will be picked up manually at the 25 homes in the alert area. On Friday morning, student dropoffs at Valley View Elementary School will take place on Deerlane Drive. No dropoffs will be permitted on Mel Canyon Road, officials said.

In the Topanga Canyon area, an evacuation warning was issued for roughly 20 homes along Santa Maria Road north of Topanga Canyon Boulevard.
