San Jose Prepares for Potential Super El Niño Floods
By Drooid · · How we work
Anticipated Storms and City Preparations
Scientists at the National Oceanic and Atmospheric Administration project a 100 % chance that a strong El Niño will persist through March, with an 83 % probability it will rank among the most powerful on record since 1950. In response, San Jose city officials and the Santa Clara Valley Water District have accelerated creek-clearing, installed a new 11,000-square-foot Emergency Operations Center, and readied a bypass tunnel to drain reservoir water before heavy rains. The city also cleared and maintained 26 miles of waterway buffer zones, enforced encampment-free zones along nearly 30 miles of streams, and prepared contracts for rapid tree-removal.
2017 Flood Legacy
The 2017 floods along Coyote Creek inundated neighborhoods, damaged more than 500 homes, forced the evacuation of 14,000 residents, and caused roughly $100 million in losses. The disaster highlighted gaps in communication and infrastructure, prompting the construction of a new floodwall behind affected properties and the expansion of emergency command facilities.
Official Statements & Responses
Mayor Matt Mahan emphasized tighter coordination between city staff and Valley Water, noting the lack of a unified map of blockage hotspots. Assistant City Manager Lee Wilcox said the expanded operations center can be fully activated within an hour, drawing on cross-trained personnel from every department. Emergency Management Director Ray Riordan described partnerships with contractors and the Red Cross to warn residents and activate shelters. Rep. Sam Liccardo warned that reduced federal disaster resources—over 4,300 FEMA job cuts, $350 million removed from NOAA forecasting, and $885 million reclaimed from Congress—could leave localities on their own during a historic winter.
Community Concerns
Residents remain uneasy about the new floodwall’s manual gate and limited monitoring, and volunteer group Coyote Mudlarks reported nine major wood blockages along a three-quarter-mile stretch of Coyote Creek. Homeless advocate Gail Osmer criticized the scant attention given to unhoused individuals in flood-risk planning.
