These California highways are most at risk of flooding during El Niño storms

San Francisco International Airport, the Bay Bridge, Highways 101, 1 and 37 and other critical California infrastructure are vulnerable to “exceptional” flooding and erosion this winter, according to a report published Monday by UC Davis.

The report highlights low-lying coasts of Central and Northern California at high risk of a combination of freshwater and seawater flooding during this year’s historic El Niño. Humboldt Bay, San Francisco Bay and Monterey Bay stand out as the most at risk to flooding.

Places listed include:

  • Pismo and Avila beaches in San Luis Obispo County
  • The Elkhorn Slough area, including Moss Landing, in Monterey County
  • The Santa Cruz shoreline, including San Lorenzo River

  • Stinson Beach
  • Highway 101 near Humboldt Bay
