Partisan political discourse still pretends as if there’s a climate change “debate,” yet the government is already acting extensively to prevent crises from rising global temperatures. Across the country, local and federal agencies are working with architects and planners to protect communities and redevelop neighborhoods in the aftermath of climate-related natural disasters. But what happens to residents who are too poor to get out of the way of storms—and too poor to return—and why is anyone rushing to live in disaster zones?
Catastrophic natural disasters share a common feature with accelerated processes of economic development: at vastly different rates, both can result in large-scale displacement. An article by Brentin Mock on environmental news site Grist uses a pithy phrase for the disparate impact climate change can have on lower-income residents: it’s the “ultimate gentrifier,” he wrote, citing the exodus of more than 300,000 low-income residents from New Orleans after Hurricane Katrina.
The description may be provocative, but studies by environmental scientists at the EPA’s Climate Change Division partly support the notion. Within the 6,000-square-mile area at high risk of flooding by 2100 due to a mid-range two-foot sea-level rise, almost 750,000 residents belong to the most socially vulnerable groups. These are most likely to be disproportionately impacted by storms and least likely to have the resources to move.
But are rich people really are moving into areas where low-income residents are being displaced by storms? Sadly, in some cases, yes. A New York Times story on high-rise condo construction in Sheepshead Bay, Brooklyn, reports that, far from retreating from flooded areas, a building boom is driving up prices.
Currently, local and federal agencies only spottily provide the necessary infrastructure and policy frameworks to protect against climate-related catastrophes ranging from forest fires in Southern California, earthquakes along the Pacific Coast, tornados and flash flooding in the Midwest, and hurricanes in the Gulf of Mexico. Adequate planning, federal aid, and environmental regulations can and should prevent disparate impacts of climate-change related severe weather events on low-income residents. In practice, prioritizing where to improve infrastructure falls to local governments that have worse financial constraints and often carry an implicit economic bias toward the most financially important areas.
In Alaska, higher temperatures are increasing erosion and thawing the permafrost, causing homes to sink in the mud. More than a dozen Inuit towns have already voted to move, including Newtok, which has acquired a relocation site through an act of Congress, and the 650-person Bering Sea village of Shishmaref, which commissioned AECOM’s Anchorage office to study the feasibility of relocation sites. Yet the cost of these moves, estimated at $214 million for Shishmaref alone, is far beyond the means of the inhabitants; a UN report on climate change and displacement notes the lack of state and federal governance structures to support these moves.
Some low-lying neighborhoods in New Orleans are undergoing a similar policy of unofficial abandonment, swallowed up by nature through neglect. These places are not gentrifying—they’re simply disappearing.
The Federal Emergency Management Agency (FEMA), reorganized in 2003 under the Department of Homeland Security and reformed since 2009 by Obama administration appointee Craig Fulgate, now talks about what it calls a “whole community” approach, emphasizing participation and engagement of a wide range of stakeholders. It needs to do more.
“FEMA has changed its rhetoric,” said Deborah Gans, who has conducted planning studies for low-lying neighborhoods in New Orleans and Red Hook, Brooklyn, most of which flooded in 2012 during Hurricane Sandy. “They don’t really know how to do it yet, but at least they’re talking the talk.”
In 2008, Homeland Security established the Regional Catastrophic Preparedness Grant program to encourage collaborative emergency planning in America’s ten largest urban regions. In New York’s combined statistical area, which includes New York, New Jersey, Pennsylvania, and Connecticut, the Regional Catastrophic Planning Team coordinated a series of Participatory Urban Planning workshops that included city and state agencies, nonprofits, community groups, private sector representatives, and even local Occupy affiliates to streamline emergency preparedness, housing recovery plans, and recovery processes in five types of communities.
In the New York area, Hurricane Sandy has increased the sense of urgency. “In New York, about a third of our housing is within our six evacuation zones,” said Cynthia Barton, who participated in the workshops as manager of the Housing Recovery Program for the New York City Office of Emergency Management.
Barton leads the FEMA-supported initiative to prototype interim housing units, designed by James Garrison, which would substitute for the improvised mesh of hotels that sheltered displaced low-income residents in the aftermath of Sandy. The interim housing units, IKEA-like prefab condo boxes that stack up to three stories high in various configurations, facilitate an urban density allowing vulnerable residents to remain within their neighborhoods in the aftermath of severe storms.
“The basis for the project has always been that none of the federal temporary housing options would work in cities and that it’s very important to keep people close to home after a disaster,” Barton said. “In terms of economic stability for people and for neighborhoods, it’s important to keep people close to their jobs. It’s important for mental health reasons to keep people close to schools and close to their support networks.”
But on the federal level, long-term infrastructure improvements are not adequately funded. In New Orleans, landscape architect Susannah Drake of DLANDstudio is working on a gray and green streetscape program for 20 blocks of the St. Roch neighborhood. “The issue is that the base condition was low in terms of the infrastructure that existed,” Drake said. “We’re adding basic amenities for what would be a normal streetscape in New York, but we’re also dealing with the challenge of having very little infiltration and having a lot of water to manage…They’re not things the federal government is necessarily willing to pay for.”
Without federal insurance and public investment in infrastructure, wealthy homeowners don’t tend to move into flood zones. But storm protection, unevenly funded by federal grants, frequently has to be supported by local real-estate development tax revenues that provide lopsided advantages to upper-income residents.
“There’s a historical inequity environmentally in a lot of these neighborhoods in need, and it’s exacerbated by climate change,” said Gans, who led a Pratt Institute planning study on how to locate emergency housing in low-lying Red Hook, Brooklyn. “New York City Housing Authority projects were generally located on land that wasn’t that valuable, and guess what? It tended to be low-lying and out of the way.”
The problem centers on whether to save the threatened neighborhoods or rezone them to exclude residential use. Shoring up a city’s flood defenses can become an opportunity to improve a neighborhood’s environmental equity, but using the prevailing market-based model, focusing stormwater infrastructure in a waterfront community will only push more housing into vulnerable areas.
“As long as we keep allowing people to build market-rate waterfront property, there will be gentrification,” Gans said. “Any development that takes place on the water will be so expensive that it will necessarily gentrify the waterfront. There’s just no doubt about it.”
In Red Hook and Sunset Park, AECOM recently released a plan to place 30-50,000 units of new housing on the waterfront—25 percent of it affordable—as well as subsidize a new subway stop, and implement green and gray infrastructure for coastal protection and flood management. Arguing for the plan as a boost to Mayor de Blasio’s OneNYC ambition to build 200,000 affordable units by 2020, the proposal also runs counter to the idea of limiting exposure to areas of growing risk.
“Why would you build more housing in an area that’s underserved by transportation and that’s in a really dangerous zone, a flood area,” asked Drake, who designed the Sponge Park concept as a green infrastructure element for the Gowanus Canal. “I’m not an economist, but I’m very pragmatic and down on building in flood plains.”
Officially, there is no means testing of emergency planning or recovery aid. Eligibility for the National Flood Insurance Program and high insurance rates affect individual decision-makers. Not so for public housing, where residents’ lack of access to resources makes issues of planning that much more grave. Because of its 6,500 public housing residents, two-thirds of the Red Hook is below the poverty line. Economically, the light-manufacturing industries scattered among its low-rises generate relatively little revenue for the city to justify hundreds of millions in flood protection.
The conflict between access to revenues and local needs seems to underlie the rapidly advancing East Side and Lower Manhattan Coastal Resiliency projects, sections of Bjarke Ingels Group’s winning Rebuild by Design competition proposal for the protection of Lower Manhattan up to 59th Street. The projects essentially erect a wall adorned with parks as a bulwark against the sea. They implicitly prioritize the centrally important economic drivers of New York City.
“Ultimately there’s a cost-benefit analysis,” said Drake. “I’m not saying that lives are less valuable in other parts of the city, but when you do an economic cost-benefit analysis between Lower Manhattan and Red Hook, and you’re looking on purely financial terms, then Lower Manhattan wins because it’s an economic driver of the city.”
If it can really be done for that amount, the estimated cost for the Lower Manhattan projects is negligible in comparison to the economic benefit. The Office of Recovery and Resiliency and the Economic Development Corporation of New York have dedicated $100 million to an integrated flood protection system (IFPS) for Red Hook. City capital is supporting a $109 million Raise Shorelines Citywide project that would mitigate sea level rise in Old Howard Beach, Gowanus Canal, East River Esplanade, Mott Basin, Canarsie, Norton Basin, and the North Shore of Coney Island Creek.
“Emergency planning should really be about future planning,” Gans said. “The way you avert an emergency is by making sure you have integrative future plans that don’t put people in harm’s way and mitigate all of the bad decisions you made historically.”
In contrast to the oblivious political climate change “debate,” local governments have already learned from recent extreme weather events that they need to act to improve their planning capacity and infrastructure. Federal agencies are also acting, putting limited resources into protecting against climate change-related disasters. Highly engineered solutions are possible, but they’re unwise as a long-term strategy in the absence of a leveling off of global temperatures and will be cost-prohibitive for low-income communities. Unless the next Congress is prepared to fund a national infrastructure program, the best way to equitably protect low-income residents will be to downzone vulnerable areas and build new public housing on higher ground. Otherwise, we’ll need to accept the fact that our celebrated revitalized waterfront is mainly for the rich.
From the Everglades to the Rockaways, this Brooklyn firm works with communities to design for resiliency
Walter Meyer and Jennifer Bolstad, founders of and partners in Local Office Landscape and Urban Design (LOLA), are earning a reputation for their innovative resiliency projects at the edges of civilization—coastlines and islands. With a multipronged approach that they describe as part architecture, part environmental remediation, and part community organization, Meyer and Bolstad are battling the effects of environmental change on cities and their populations. Managing editor Olivia Martin talked with them about LOLA’s approach to resiliency and future-proofing the planet—from working on post-Hurricane Sandy conditions in the Rockaways to remediating coastal areas of Florida.
The Architect’s Newspaper (AN): You say that resiliency is the new sustainability. Why?
Walter Meyer: It’s a new buzzword, so people confuse it and interchange it with sustainability as though they are the same thing. But sustainability is a derivative of Frederic Clements’s climax theory, in which a field, for example, will change each decade, from soil to weeds to shrubs to trees and then climax as a hardwood forest—this is a snapshot of nature in 3-D.
What emerged after World War II was a new theory of the natural cycles of time. Rather than seeking an equilibrium theory of nature, there is a disequilibrium, where nature is trying to balance itself and adapt to change. Those who can anticipate and respond to change quicker are the ones who have the upper hand.
The big difference is that resiliency is dynamic and changing, while sustainability is static. In terms of scale, sustainability is holistic and more big-picture, and resiliency is more local. So I think of sustainability as an old model but still an important tool.
AN: Do you have examples of where sustainability failed us and why it should no longer be considered the gold standard, so to speak?
Jennifer Bolstad: Well, a few years ago, I consulted on One World Trade Center, which is a very sustainable building [LEED Gold]. But when the mechanical system drowned in Hurricane Sandy and couldn’t be used anymore, the firm in charge ultimately decided it was cheaper to abandon it and leave several floors uninhabited rather than fix it.
Meyer: Also during Hurricane Sandy, all of the buildings that ran on photovoltaics failed because the city grid was down. So, literally, every single building with solar was down. This is because there is a law that if the grid goes down, you can’t back charge the line with your solar panels, because you’ll zap the workers trying to fix the grid. Since then, they invented a hybrid inverter that “islands” the building into a microgrid, so it can function independently off of the grid. There needs to be a dynamic relationship with nature, and we should be creating multilayered systems.
AN: You have a lot of work in Florida right now that deals with water management. How does resiliency factor into those projects?
Meyer: All of the articles written about Miami focus on the ocean and city. It’s all about the ocean—and that makes for good headlines. But what’s missed is that Miami’s most vulnerable areas are in the Everglades, on the west side of the city, because they have freshwater, five feet higher than the ocean, that can’t become diluted with salt water or else Miami loses its water source.
The area near Everglades National Park is particularly at risk because the main flow of the water runs north–south, down from Lake Okeechobee to Florida Bay, and a secondary flow of water runs east–west—like a spine and ribs. Originally, the secondary water flow moved through transverse glades and occasionally wet bogs and sloughs. Since the channels weren’t actual rivers, the city filled them in, and now, when it rains, the houses on those streets along these former sloughs flood. The homes are considered Repetitive Loss properties and the owners cannot collect insurance for the damage anymore. The buildings’ foundations are cracking, due to the water infiltrating the alkaline bedrock, literally melting it. We are trying to open up more options to the people who are stuck in these houses but don’t want to leave their community.
Normally, there is a lot of discussion about design activists, but we are more like community organizers—we want to engage the residents themselves. It’s a lot of listening and then designing and showing them what legal options are available, or creating new ones. One option is a CLT, a community land trust—where everyone buys into this idea, and you work with a public–private partnership, such as a developer and the county. For this neighborhood, it’s about creating high density along the edge of the vulnerable corridor, along the slough of the transverse glades, and doing this three blocks at a time.
If you can organize just three blocks—the center of the slough, a transitional, and a bank—then this creates a housing swap, where the residents can continue their normal lives and not have their schedules disrupted. So, for example, you can move out of the home into a temporary housing unit; then the home will be demolished and turned into a flood storage park, and you will have the option of moving or the right of first refusal to a new high-density, 40-percent affordable housing unit nearby. This makes more sense than simply moving everyone to higher ground because, then, those who are already at higher ground could be dislocated due to rising real estate costs—already Florida developers are looking at luxury housing inland—and this creates new levels of climate refugees.
AN: So, resiliency aside, is relocating more responsible than fixing?
Meyer: Well, that is what leads to climate gentrification; the issue of scale is a major one. If you take a holistic approach and just get everyone out of harm’s way, then you aren’t paying attention to the social fabric. For example, Staten Island was a state buyout project; the government essentially said, “We’ll buy your house, and you can take the money and run.” The problem with that is then the people basically had to move out to Newark because the buyout price point doesn’t acknowledge the gentrification, and $200,000 or $300,000 won’t get you another house in the city. In the Edgemere Urban Renewal Area, in Rockaway, the Department of Housing Preservation and Development and the Office of Recovery and Resiliency offered more options than just a buyout—such as housing swaps and other solutions at the neighborhood scale.
Bolstad: We focus on the built environment in a way that looks at how cultural issues touch the ecological issues. In the Florida project, people very much want out of their houses that are constantly flooding, but they still want to stay within a five-mile radius so they can be near family and keep their routines. It’s not a one-size-fits-all approach, even if you believe in a long-term retreat from those areas. Otherwise, you end up with people who are not there by choice, like when Robert Moses dislocated people in the Bronx in the 1960s and moved them out to the beach. Economically vulnerable populations ended up in environmentally vulnerable areas.
And it’s not just the built environment. Even if we aren’t preserving the area for housing in the long term, then the environmental situation needs to remain. That barrier [the Rockaway peninsula] is the first line of defense in the city and Lower Manhattan, and, without active management of the environment of that place, it risks the rest of New York City.
Meyer: I like to quote my mentor and city planner Ronald Shiffman when we talk about these issues: “These disturbances don’t discriminate, but our reaction to them can.” We want to make the most just city we can.

One might not expect Iowa City, a midsize heartland town of 70,000, to be on the forefront of urban sustainability issues. But Iowa City has everything to lose if climate change isn’t addressed. In 2008, a massive flood caused an estimated $64 billion in damage to the state, roughly equivalent to that caused by Hurricane Sandy. That flood was preceded by 239 tornados, which hit the Midwest over a nine-day period.
Iowa City, a UNESCO City of Literature, has a strong, culturally active citizenry, and now it is working to channel that energy into securing its environmental future. After the flood waters subsided, and the tornado damage was clear (damage from both of those events is still evident eight years later), a group of Iowa City residents began to seriously think about how design could be used to achieve a more sustainable urban center. “Ecopolis Iowa City” was organized to brainstorm urban restoration, biodiversity, local food, inclusionary and urban designs, renewable energy, and transportation initiatives for the future of the city. Initially holding informal meetings, Ecopolis Iowa City eventually started to sponsor forums that would use storytelling, music, and conversation to identify and generate ideas. From 2014 to 2016, the events eventually turned into a movement.
The city’s 2015 fall election saw a progressive council majority win for the first time in nearly 50 years. In spring 2016, Mayor Jim Throgmorton issued a “Regenerative City” proclamation. The proclamation set goals to “replant native prairies and trees to store carbon in the soils; expand urban agriculture; to power our city and neighborhoods efficiently through green building designs and renewable energy; to expand citywide recycling and composting through a zero waste ordinance; to make low-carbon transportation choices; to grow green jobs and support companies actively greening their operations.” By summer, the ideas from the Ecopolis Forums were worked into a proposed Iowa City Climate Action Plan.
The plan aims to expand and guide the regenerative city initiatives. Iowa City is already investing $60 million into raising a major route into the city above the 100-year flood level, but the plan calls for many more actions at different scales. From establishing protected “ecodistricts” to enforcing new sustainable building requirements, the plan may greatly affect the city’s future fabric. The plan sets greenhouse gas emission and transit diversity goals through 2030, with an eye on changing the way average citizens understand their impact on the environment.
Though the Iowa City Action Plan has not been formally adopted by the city, Ecopolis points out that the six million sandbags Iowa City residents filled to try and save their city in 2008 is a sign they are ready and able to make major changes. And with Ecopolis founders now on the city council, the time is better than ever.
This article was part of our Oct. 12 issue which focused on how water is shaping today’s landscape architecture and urbanism. Communities face deluges and droughts—for some, the stakes can be survival itself, but others see opportunities for decadence. To explore these stories from around the U.S. and the world, click here.
HISTORYThe first topic of the day, History, was moderated by Reinhold Martin (Columbia GSAPP) and included presentations from Daniel A. Barber (University of Pennsylvania, Architecture), Deborah R. Coen (Barnard College, History), Gregg Mitman (University of Wisconsin, History), and Eyal Weizman (Goldsmiths, University of London, Visual Cultures). Addressing different moments in history, the speakers collectively unveiled how ecological understandings dictate societal development.
POLITICSThe second topic, Politics, was moderated by Laura Kurgan (Columbia GSAPP) and included talks from Michael B. Gerrard (Columbia University, Earth Institute and School of Law), Saskia Sassen (Columbia University, Sociology), Richard Seager (Columbia University, Lamont-Doherty Earth Observatory), and Christian Parenti (New York University, Liberal Studies). Each presentation addressed environmental failures, which Kurgan called “sobering,” and the related risks facing architects, planners, and builders. Before heading to COP21 to represent the Marshall Islands, Gerrard told the audience in Wood Auditorium, “Architects might be legally liable for failure to design for foreseeable climate change.”
UNCERTAINTYJesse M. Keenan (Columbia GSAPP and CURE) moderated Uncertainty, which included talks from Radley Horton (Columbia University, Earth Institute and NASA Goddard Institute for Space Studies), Adrian Lahoud (Royal College of Art, London, Architecture), and Kate Orff (Columbia GSAPP and SCAPE). The presentations unveiled each profession’s individual roles and how they overlap. Horton works with quantitative climate science; Lahoud uses the qualitative method of narrative; and Orff works in both realms. Keenan concluded, “Architects and planners are mediators. They are helping make that translation to define values and vulnerabilities and to weigh what that really means.”
VISUALIZATIONThe final section, Visualization, was moderated by Mark Wasiuta (Columbia GSAPP) and included presentations from Heather Davis (Pennsylvania State University, Institute for the Arts and Humanities), Laura Kurgan, Emily Eliza Scott (ETH Zurich, Architecture), and Neyran Turan (Rice University, Architecture). Again, the presentations covered a wide spectrum of curation, ranging from Davis’s discussion of subject-object relationships to Kurgan’s video visualization of climate change data, EXIT, currently on display at COP21. Wasiuta, said in the panel discussion, “Laura’s work produces a different type of knowing, or knowability. Fascinating, the idea of curating a dataset: curating as the construction of a political form.” The day’s presentations ended with keynote speaker Dipesh Chakrabarty (University of Chicago, History). Chakrabarty’s talk, “The Human Significance of the Anthropocene” was a fitting way to pull together the wide-ranging but interrelated disciplines contributing to the conference. Videos of the conference will appear on Columbia GSAPP’s YouTube channel in the coming weeks.
Students at RISD imagine how a climate change museum in New York City could reclaim a vulnerable site
It is by no means a simple problem to solve. Multiple licenses and approvals would be needed from a variety of agencies, including the city itself, the U.S. Environmental Protection Agency, and others. But there is great enthusiasm among experts for trying the experiment. Blue infrastructure is a key recommendation of the Detroit Future City visionary framework and has been much talked about in recent years, but nothing of this magnitude has been done so far in Detroit. So far, "blue infrastructure" in metro Detroit has meant the creation of porous parking lots and so-called "green alleys" that allow rain and snowmelt to filter down into the ground beneath instead of running off into sewers.Across the nation urbanists and landscape designers are embracing innovative stormwater capture and retention techniques as concerns over climate change, flooding and drought collide with a renewed interest in public spaces and site design.
