San Francisco crews prepare for downed trees as storm blows through

SAN FRANCISCO (KGO) -- Public works crews are standing by in San Francisco in case the latest round of wind and rain triggers mudslides and topples trees.

The crews are paying special attention to an unstable hillside next to Glen Canyon.

Next to Glen Canyon, O'Shaughnessy Boulevard was closed Wednesday once again while they prepared to stabilize the hill.

Cars were forced to turn around on as crews closed most of the road leading to a rock slide.

The Department of Public Works installed a concrete barrier to secure the hillside and was set to begin knocking loose rocks first thing Thursday morning.

Tom Podesta lives in the Glen Canyon neighborhood. "I was taking the bus down here, but I had to walk," Podesta said.

The Office of Emergency Management said conditions were unstable. "We had a lot of rain this past week, with more rain on top of already saturated soil it increases the risk of mudslides and landslides," Francis Zamora told ABC7 News.

Despite the rain and winds, the National Park Service was still doing scheduled maintenance, pruning trees to make sure they don't pose any danger of falling.

We're expecting winds of up to 45 miles an hour, so our trees area already weakened, so we can expect more falling tress. If you see see a downed tree, call 311. If you see a downed wire, call 911.
