US · Published Nov 14, 2026
• San Jose is mobilizing resources to address heightened flood risks this winter due to a powerful El Niño system.
• The city has declared a local emergency, enabling faster response to potential flooding along its 140 miles of waterways.

Impact & Risks

Low-lying areas like Alviso face significant flood risks, with potential inundation from rising San Francisco Bay waters and heavy rainfall. The Guadalupe River and Coyote Creek pose additional threats to nearby neighborhoods. While flood control measures have been implemented, including levees and pumping systems, residents remain concerned about the possibility of levee breaches or system failures. Homeless encampments near waterways are also at risk of displacement.
