Bay Area vulnerable to extreme winter flooding, UC Davis report warns

The Brief

  • A new report from the UC Davis Road Ecology Center warns that a combination of King Tides, a Kelvin Wave, and El Niño conditions could cause severe winter flooding across the Bay Area.
  • Low-lying shoreline areas, including Alviso in North San Jose, San Mateo and Alameda counties, San Francisco International Airport, and the eastern approach to the Bay Bridge, face significant risk.
  • Coastal areas further south, such as Santa Cruz Harbor and Moss Landing in the Monterey Bay area, are also listed as high-risk locations.
