“This was a whole different reality,” Mr. de Blasio stated, in a morning look on MSNBC. “The lives weren’t lost in the coastal areas, which is where Sandy hit. Lives were lost in places far away from any seashore because of stunning amounts of water coming down so quickly, flooding basements and catching people unaware.”
At the identical time, the mayor appeared to acknowledge that extra aggressive techniques to safeguard lives — resembling journey bans and evacuations of basement flats — weren’t employed and may must be sooner or later.
“This was not part of any previous playbook, but we’ve got to literally change the whole way of thinking,” he stated. “Because as good as some of the projections are, they can’t always keep up with weather.”
Anger appeared notably palpable in Queens, the place 12 folks perished as water gushed into subterranean areas, leaving residents to drown in their very own properties. Many of these basement flats had been unlawful, in keeping with the town’s Department of Buildings.
“It is unacceptable that we did not prepare for Ida with the same rigor that we did for Henri, and that is a failure on the city’s part,” stated Francisco Moya, a metropolis councilman from Queens. “No one should have been driving, trying to escape the storm or stuck at work because of dangerous flooding, and no one should be at home getting flooded not knowing when the water will stop or what to do, and risk losing their life.”
The destruction and human toll within the New York area appeared particularly putting contemplating that Ida had already blown via the Gulf Coast, hitting New Orleans on Sunday with far stronger winds however with fewer deaths.
The metropolis issued official warnings early Wednesday morning, when the town’s Office of Emergency Management cautioned that the remnants of Ida might trigger flash flooding. The metropolis stated it additionally activated its flash flood emergency plan, which concerned cleansing out clogged catch basins. It put its downed-tree activity power on alert.
State transportation officers had been dispatched to clear culverts and different drainage techniques of particles, in keeping with the governor’s workplace, with inspections and patrols to evaluate rising waters. An array of apparatus — from chain saws at hand instruments — was deployed, in addition to pumps and mills.
By Wednesday night, the predictions had grown extra dire. New Yorkers had been warned of tornadoes and urged to maneuver to larger floor. Calls to the town’s 911 emergency system and 311 assist line started to surge round eight p.m., in keeping with metropolis officers.
For all that, the depth of the rains stunned forecasters.
Arthur DeGaetano, director of the Northeast Regional Climate Center at Cornell University, stated the flash floods of Wednesday evening resulted from not one storm however a number of small storms whose interactions with one another had been onerous to foresee. In the top, these storms ended up working over New York City, one after one other.
“It was just like New York City was on the train tracks, and the storms were a train going down those tracks and they persisted for hours,” he stated. “I would say that the forecast for this storm, or the remnants of this storm, of heavy rain over the city a day in advance were actually pretty darn good. I don’t think anybody at that point in time could have imagined six inches of rain in a six-hour period, essentially.”

Although nobody might have foreseen the fierceness of two climate occasions 10 days aside, metropolis officers in May launched a citywide evaluation of flooding attributable to rainfall.
The report sought to grapple with predictions that the town would expertise a rise in “extreme rainfall events” over the course of this century, together with a doable 25 % improve in annual rainfall and a considerable improve within the variety of days with greater than an inch of rain.
Part of that plan included a dedication by the town to replace its flash-flood response procedures. Among different issues, it stated that by 2023, the town ought to “predraft messaging regarding potential dangers for residents living in basement dwellings to be used for outreach and notification in advance of forecasted extreme rain events.”
The de Blasio administration has additionally put cash behind its effort to make the town extra resilient to water, together with a $2 billion dedication towards enhancing drainage in Southeast Queens. It was unclear how a lot of that has been spent.
But the storms that hit New York this week pre-empted long-term strategic planning by metropolis officers, inflicting a extra brutal real-world actuality.

Today, I’m asserting the N.Y.C. Climate Driven Rain Response. We must deal with this otherwise as a result of we’ve now been proven a completely totally different state of affairs. It is local weather pushed and that’s essential to place upfront. Because it’s not just like the rain we used to know. It’s simply not. It’s a distinct actuality of pace and depth that we now have to grasp will probably be regular. Wednesday night was the primary time the National Weather Service in historical past, decided that there wanted to be a flash flood emergency in New York City. Not the traditional warnings we get, however on the Wednesday evening, they stated that is a completely totally different factor. We have to reply that with using journey bans. Now, a journey ban isn’t one thing to do evenly. We’ve solely accomplished it a couple of instances beforehand, notably throughout huge snowstorms, blizzards. But sadly, what we discovered on Wednesday evening is a journey ban is the type of software we may have to make use of far more ceaselessly, which might imply, for instance, that that very same morning or that day earlier than, telling folks there’s a likelihood that a journey ban will probably be activated. And as soon as it’s activated, folks should go away the streets, get out of subways, et cetera, instantly. For people in basement flats and in another areas of the town as effectively, if we’re seeing this sort of rain, we now have to have an evacuation mechanism that may attain them. And once more, this can be a very forceful measure. It’s not simply saying to folks, it’s a must to get out of your house. It’s going door to door with our first responders, and different metropolis businesses to get folks out.

“I’m not questioning the needs of Manhattan in terms of resiliency. I’m questioning the sense of equity across the five boroughs,” Mr. Treyger stated.
Mr. Brannan is the sponsor of laws that might require the town to develop a plan to guard the town’s total 520 miles of shoreline. The laws had 38 sponsors however has not moved partly due to considerations over value from the de Blasio administration.
Mitch Schwartz, a spokesman for Mr. de Blasio, stated the administration supported the “intent” of the laws however stated that learning even one neighborhood for a plan of that dimension would value tens of millions of . The City Council could transfer to move the laws earlier than the mayor’s time period ends in January.
The resiliency of the town’s subways — which suffered change malfunctions, floods and systemwide shutdowns and slowdowns in the course of the storm — has additionally been a long-term concern.
Some service disruptions continued into Friday afternoon.
