Flooding, Mudslides Close Roads Across Contra Costa County

CONTRA COSTA COUNTY, CA — Flooding and mudslides Monday closed roads from Martinez to Morgan Territory.

In Orinda, El Toyonal Road was closed Monday afternoon but Davis Road reopened.

Flooding closed Highland Road in southeastern Contra Costa County late Monday morning, between Carneal Road and Manning Road. Only local traffic was being allowed in. County public works officials said the best detour was Carneal Road to Manning Road in the eastbound direction. Then take Manning to Carneal in the westbound direction.

Near Martinez, the intersection of Arthur Road and Pacheco Boulevard was closed to all traffic due to flooding. Officials said to please avoid the area.

And Morgan Territory Road was closed between addresses 5477 to 5649, due to mudslides. Only residents were allowed in the area.

In Moraga, Mulholland Ridge Open Space is closed for safety due to the ongoing storms, town officials said Monday.

Flood Watch Continues

A National Weather Service flood watch remains in effect through Tuesday for all of the Bay Area. Residents should expect widespread flooding, mudslides and the rapid rise of creeks and rivers.

"A lot of our rivers and streams today are really at some of their limits," said Weather Service Meteorologist Brayden Murdock.

The risk of flooding was likely to peak Monday night in the region's most impacted areas as rains continue and run-off from higher elevations filter down to already swollen waterways, Murdock said.

The storms have had widespread impacts in practically every corner of the Bay Area, with flooded roadways and downed trees and powerlines creating hazardous driving conditions and power outages that affected 14,076 PG&E customers by late Monday morning.

The wet weather is expected to continue for at least the next week or so, with the largest rainfall amounts focused on the North Bay, Murdock said.

"The wet time is going to continue and our long-term outlook still shows wet conditions," he said.
