After Ida's fury, infrastructure key in preventing misery

Deadly flooding delivered to the Northeast by the torrential rains of what remained of Hurricane Ida has brought a new urgency and a fresh look to how roads, sewers, bridges and other infrastructure must be improved to prevent such a catastrophe from happening again.

The world is changing and “our whole mindset, the playbook that we use,” must change too, New Jersey Gov. Phil Murphy said Thursday as he toured Mullica Hills, New Jersey, where a 150-mph (241 kph) tornado splintered homes. “We have got to leap forward and get out ahead of this.”

“I don’t think many people could have predicted the severity of the loss of life and damage done by the flash rains,” said Dr. Irwin Redlener, founding director of the National Center for Disaster Preparedness at Columbia University. “People drowning in their basement apartments, in cars and so on is not something we typically would ever see in New York.”

Hochul promised new answers to pressing questions, like whether...
