SANTA ANA, Calif. (CNS) — Orange County supervisors have declared a state of emergency in response to the winter storms that have battered Southern California, on the same day that Gov. Gavin Newsom added the county to his list of those receiving a state declaration of emergency due to storm damage.

The Board of Supervisors took the action at Tuesday’s meeting in part to help families whose homes are in danger of sliding down a hillside in Newport Beach, Supervisor Katrina Foley told local media.

“We have homes that are teetering on falling down into the Back Bay off of the hillside,” Foley said.

“We have one family that has senior citizens, elderly people almost 90 years old, who had to be removed from the house because it was red tagged,” she added. “ ... They already have a lot of damage and they’re having trouble because insurance isn’t covering it. So, they’re having to go out of pocket to just save their homes.”

On Tuesday, Newsom added Orange, Alpine and Trinity counties to the 40 counties he previously proclaimed a state of emergency for since the start of severe winter storms in late February. The declaration authorizes federal assistance to support state and local storm response efforts.

Orange County was under a flood advisory until 4:40 a.m. Wednesday, after rain fell on the region for most of Tuesday. Late Tuesday, Caltrans announced that all lanes of Pacific Coast Highway were closed between Seapoint Street and Warner Avenue in Huntington Beach due to flooding.
