When Superstorm Sandy made landfall on October 29, 2012, it pushed 13 ft of storm surge into New York Metropolis’s harbor, sweeping throughout the Brooklyn and Queens waterfronts and wiping total neighborhoods off the map in Staten Island. Flooding knocked out energy in Decrease Manhattan, plunging downtown into near-total darkness as water rushed by the streets. The storm induced $19 billion in damages within the metropolis alone, and it was clear that future storms might be even worse except one thing modified.
Lower than a yr later, the Obama administration unveiled an enormous federal initiative to make sure that the town not solely recovered from Sandy, however constructed again higher. The initiative, dubbed Rebuild by Design, promised to funnel cash towards long-term local weather adaptation measures within the hardest-hit areas, supplementing the standard barrage of catastrophe help with cash earmarked for forward-looking initiatives.
To say that officers aimed excessive can be an understatement. The Division of Housing and City Growth, or HUD, which managed the initiative, threw its weight behind an concept known as the “Huge U.” The plan, drafted by the agency of Danish celeb architect Bjarke Ingels, proposed to wrap the island of Manhattan, the monetary and cultural capital of the US, in miles of berms and synthetic shorelines, creating an enormous grassy defend that will each improve city inexperienced area and defend the town from storm surge. The feds doled out an eye-popping $335 million for the primary section of the Mission, which quickly captured the general public’s creativeness, partially because of iconic renderings from Bjarke Ingels Group (BIG) that confirmed a inexperienced paradise enfolding Manhattan. Ingels referred to it as “the love-child of Robert Moses and Jane Jacobs.”
In case you stand in Battery Park on the southern tip of Manhattan right now, 10 years after Sandy, it may be arduous to think about that the town is about to make the Huge U imaginative and prescient a actuality. Look somewhat nearer, although, and there are indicators of progress. A number of items of the borough’s flood barrier have damaged floor up to now yr, and nearly all the cash for the system has been secured, with just a few items left to fund. After years of planning, design, and debate, the bodily construction is beginning to take form.
“When you begin to see it in actual life, it feels completely completely different,” mentioned Amy Chester, the managing director of Rebuild by Design, which has gone on to assist different cities plan resilience initiatives. “I labored in metropolis authorities eternally, and I didn’t count on all these initiatives to occur, nevertheless it occurred.”
An early rendering of the Huge U berm construction on the Battery. The plan first emerged within the aftermath of Superstorm Sandy. Courtesy of Bjarke Ingels Group The Huge U was a check case for large-scale local weather adaptation. It wagered that cities may use a catastrophe like Sandy as a second to rethink their relationship with nature, somewhat than simply rebuild what had existed earlier than.
In some methods, the guess paid off. The Huge U mission did handle to safe funding, and it’s now being constructed, albeit years delayed and in modified kind. After nearly a decade of design work and public engagement, the town has confirmed that unconventional adaptation initiatives can work, and that cities can look past conventional flood partitions and levees.
In one other sense, although, the Huge U is a actuality verify for these large initiatives. The mission was kickstarted because of a rush of post-disaster cash from a presidential administration that prioritized adaptation, nevertheless it couldn’t have gotten up to now with out New York Metropolis’s unparalleled native sources. As Chester places it, New York is a “completely different monetary animal” than the remainder of the nation. Whereas different jurisdictions rely closely on the federal authorities to fund large infrastructure initiatives, the town may also command enormous quantities of municipal and state funding, which helps open the door for extra formidable and forward-looking initiatives. Absent a revamp of how the federal authorities funds local weather adaptation, such initiatives will proceed to stay out of attain for many cities.
“There are such a lot of communities throughout the shoreline together with different main cities like Houston, Los Angeles, Seattle, Boston, Miami, Tampa,” mentioned Linda Shi, an assistant professor of metropolis planning at Cornell College who research local weather adaptation. “Are they going to see such sums of cash? After which what about a lot smaller municipalities? They for certain usually are not going to see such ranges of funding. That’s an actual problem, to consider how our infrastructure spending goes to satisfy that hole.”
The primary activity within the Huge U mission was to interrupt Ingels’s dramatic imaginative and prescient into achievable chunks.
The $335 million that the town obtained from HUD went to fund an enormous section alongside the east facet of Manhattan, one of many metropolis’s hardest hit areas by the storm. For hundreds of years, this a part of the island consisted largely of wetlands, earlier than builders stuffed it in to make room for dense residential neighborhoods and public housing developments. When Sandy hit New York, its storm surge sought out these historic low-lying stretches, however the tidal channels and mudflats that had as soon as absorbed extra water have been lengthy gone, changed by concrete buildings and streets.
Ingels’s preliminary plan for the east facet known as for an enormous tiered berm that will slope up from the water at East River Park, however this imaginative and prescient quickly hit a roadblock: Officers in Mayor Invoice de Blasio’s administration decided that constructing the berm can be too disruptive for a close-by freeway — the busy FDR Drive — and a subsurface energy line owned by the utility ConEd. As an alternative they determined to raise the entire park on eight ft of synthetic fill. However the metropolis made just a few critical missteps in speaking with locals concerning the new plan, and a coalition of locals, artists, and activists quickly banded collectively to oppose it, arguing that it might take away bushes and cut back entry to a helpful neighborhood area.
Regardless of the general public relations nightmare, the town started building work on the east facet mission in earnest late final yr, and has since ripped up about half the park. Dozens of vehicles, cranes, and backhoes now fill the positioning, laying the groundwork for the fill that may increase it off the bottom. Town now expects the mission to be full in 2026.

Erik McGregor / LightRocket through Getty Pictures There’s the same mission within the works on the other shore of Manhattan, in an space known as Battery Park Metropolis. Constructed within the Seventies on synthetic land that extends out into the Hudson River, the neighborhood is ruled by a state authority that may challenge its personal bonds, permitting native leaders to fund an $800 million resilience scheme to assemble one other section of the Huge U. As in East River Park, the plan right here is to create a tiered collection of elevated lawns that may cease coastal flooding from pushing inland.
However similar to throughout city, this plan isn’t going over properly with some locals, who’ve objected to the truth that it’ll shut the park for a number of years. Earlier this summer time, the campaigners attracted the eye of Republican gubernatorial candidate Lee Zeldin, who urged the state to pause building till native considerations are heard.
“Residents have identified that Wagner Park didn’t expertise extreme flooding throughout Superstorm Sandy,” mentioned Zeldin in a press release to the press. “Others have raised considerations concerning the exorbitant price.” A bunch of locals is pushing an alternate design for the park, however crews are nonetheless anticipated to start building within the coming weeks.
The third and most troublesome section of the waterfront to guard is the two-mile stretch between these two different initiatives: the southern fringe of Manhattan, stretching from decrease Battery Park Metropolis previous Wall Road and up towards the East Facet. This stretch of shoreline is dwelling to the towering skyscrapers of the Monetary District, the offramps of the Brooklyn and Manhattan bridges, the packed historic neighborhood across the South Road Seaport, and one other dense cluster of high-rise housing developments, to not point out a thicket of vital transportation infrastructure, together with the elevated FDR Drive expressway and a subterranean automobile tunnel to Brooklyn.
As a result of the realm is so overbuilt, with just a few dozen ft of free area between the water’s edge and the closest avenue or constructing, the town doesn’t have the room to construct large flood partitions or berms like those it’s developing in East River Park. A lot of the waterfront territory within the neighborhood sits on concrete piles, which suggests it possible couldn’t help the two-story construction wanted to guard the low-lying Monetary District from an enormous storm occasion; the dense community of underground transportation and energy infrastructure solely additional complicates such an effort. Plus, most of the buildings within the Seaport district are designated historic landmarks, making it even tougher to construct one thing new of their midst.
Confronted with all these challenges, designers needed to get inventive. In a single a part of the issue space, close to the dense Two Bridges neighborhood, the town selected a novel technological answer from the unique Huge U plan: a $500 million array of deployable flood partitions that may flip up out of the bottom throughout storm surge occasions, creating a brief water barrier. Mayor Eric Adams broke floor on that mission this week, and additionally it is anticipated to complete in 2026. Additional down the shore, the town hopes to increase a synthetic shoreline out into the water, making a two-tiered berm with one section that soars fifteen ft into the air and one other that sweeps down towards the river.

A modified model of the mission is now underneath building in Decrease Manhattan. Courtesy of Bjarke Ingels Group Discovering the funds for this final piece could also be tough. A lot of the cash for the flip-up flood partitions arrived six years in the past thanks to a different Obama-era grant program that funded novel resilience methods, however the berm across the Seaport will price round $3.6 billion, in keeping with the town’s newest estimates, and can take greater than a decade to finish. Until the town is hit by one other Sandy, there possible gained’t be one other enormous pile of post-disaster federal cash for this mission, which raises questions on how the town pays for it. A latest federal grant to assist help the mission supplied solely $50 million, at most 1 % of the overall price of the mission.
Victor Papa, the president of the Two Bridges Neighborhood Council, which represents residents within the space, mentioned he’s optimistic the mission will come to fruition, and mentioned he wasn’t disturbed by the lengthy timeline.
“We’re feeling very assured,” he instructed Grist. “I’m of the thoughts that when a mission impacts hundreds of individuals, in hundreds of housing items, that isn’t an in a single day course of, that’s a course of that’s going to have a studying curve. I feel the town did job of their design and their implementation.”
Even with a lot of the funding locked down, the trajectory for ending the Huge U is troublesome to foretell. The development timeline for the remainder of the mission stretches to the tip of the last decade and past, and that’s assuming all the things goes properly. Future mayors could should cope with controversy over building impacts and price overruns. The lengthy timeline can also jeopardize the effectiveness of the mission: the flip-up flood gates, as an illustration, solely present safety towards the sea-level rise that may happen by 2050, which may make them insufficient as little as twenty years after they’re accomplished. There’s additionally the chance that one other Sandy may strike whereas the town remains to be constructing the Huge U, setting the timeline again even additional.
“I feel a number of the estimates on time that the town put out proper after Sandy have been absolutely the best-case state of affairs, and never all the things turned out to be finest case,” mentioned Daniel Zarrilli, a particular advisor on local weather and sustainability at Columbia College who served as a local weather coverage advisor to Mayors Michael Bloomberg and de Blasio. “These are large, billion-dollar infrastructure initiatives and issues do are likely to take time, which is unlucky, as a result of time isn’t on our facet.”

Christos Pathiakis / Getty Pictures The present framework can also be notable for what it leaves out — the town’s ambitions for the Huge U are smaller than the unique proposal from the Rebuild by Design days. The unique berm construction conceived by Ingels would have prolonged from forty second Road on the East Facet all the way in which across the island and up the West Facet to 57th Road, however the metropolis has lopped off sections on each side. Moderately than push the mission up the perimeters of the island, the town scaled again its ambitions to the barrier section it knew it may afford.
The accountability for shielding the remainder of Manhattan and New York Metropolis now lies with the U.S Military Corps of Engineers, the nation’s chief builder of flood initiatives. In most different cities, the Corps may need taken cost of storm surge adaptation from the start, drafting an infrastructure mission and securing cash for it from Congress, however that wasn’t the case in New York. The pot of cash the town obtained from HUD allowed it to pursue the nontraditional imaginative and prescient of the Huge U, and leaders later rejected the Corps’ controversial proposal to create a five-mile storm gate throughout New York Harbor.
Now, although, the Corps has returned to fill within the gaps: The company this month unveiled a $52 billion plan to construct a collection of storm gate buildings throughout the town and in New Jersey as properly. One construction would prolong deployable flood gates up the West Facet of Manhattan, approximating the extent of Ingels’s authentic scheme. If executed properly, the Corps plan would additionally assist bolster flood resilience in susceptible components of the town that didn’t obtain the identical jackpot of HUD cash that Decrease Manhattan did. There have been different formidable Rebuild by Design ventures for a few of these locations too, together with the Bronx and Staten Island, however none so formidable because the Huge U. By itself, a flood barrier round Decrease Manhattan wouldn’t assist these areas, and would possibly even push extra water towards them throughout storm surge occasions.
“There’s solely a lot cash that the town had, and the federal funding streams allowed us to do some work, however not all of it,” mentioned Zarrilli. For the remainder of it, he mentioned, “we want the Military Corps.”
Even this some-but-not-all achievement can be troublesome to duplicate in different cities that don’t have New York’s native sources or a pot of restoration cash from a pleasant presidential administration. Bond measures and federal resilience grants will help fund smaller-scale adaptation initiatives, however transformative inexperienced infrastructure on the size achieved in Manhattan will possible stay out of attain elsewhere in the US.
Moreover, Shi, from Cornell, cautions that new infrastructure can’t be the one means we adapt to local weather change. The Huge U could also be an admirable instance of how cities can rebuild for rising seas, nevertheless it gained’t work except accompanied by different measures that shift improvement away from flood zones and assist folks relocate from the riskiest locations.
“I feel there’s a sure type of hazard to the siren tune that the Huge U sings for us, as a result of it’s so visually interesting that we would suppose that it’s going to remedy the issue by itself,” she mentioned. “However that’s only one type of innovation. And that very same type of creativeness must be there in these … non-design areas to ensure that all of this to truly pencil out.”
