Miami’s flyaway cranes could damage high-rises during Irma
While Houston and other parts of Texas grapple with the fallout from Hurricane Harvey, another storm, Irma, has shaped up to be the third most powerful storm ever recorded in the Atlantic, with Category 5 winds measuring up to 185 miles per hour as of Wednesday evening.
Having watched Irma pummel through the Leeward Islands in the Caribbean, the City of Miami—which has long known of its innate susceptibility to flooding and erosion—prepares itself for what may well be an incredibly devastating blow this weekend.One of the more urgent concerns raised by the city is the damage that could be wrought by 20 to 25 construction cranes scattered throughout the city, which can withstand winds only up to 145 miles per hour and take two weeks to properly disassemble. Since the storm's potential path was only projected last Friday, there will not be enough time to take down the equipment.
Late yesterday, Miami-Dade County issued a mandatory evacuation order for its coastal cities, including Miami Beach, and the city is continuing its preparation efforts by clearing the downtown harbor, closing public parks, and supplying sandbags for flood protection efforts. For those living in affected areas, the Florida State Emergency Response Team has activated an Emergency Information Line at 1-800-342-3557.

Making No Small Plans
Optimism fuels Miami’s mega-developments, but a denser Miami isn’t a sure thing

New York or Los Angeles?
These are the two contrasting models of urbanism that Raymond Fort, designer at Miami-based architecture firm Arquitectonica, cites when asked about Miami’s future. In New York, numerous walkable neighborhoods—whose density, convenience, and character are major assets—are connected by a robust public transportation system. In Los Angeles, low density and car-oriented urbanism is the norm outside the downtown core (though transit-oriented development has begun to spread in recent years). Many developers working in Miami are clearly enthusiastic about the New York model. However, that future isn’t guaranteed: The potential for car-dominated sprawl and other hybrid models still exist.
Arquitectonica is behind Brickell City Centre, a 5.4-million-square-foot complex of offices, luxury condos, a hotel, and ample retail south of Downtown Miami. Developed by Swire Group, Brickell is one of the many large, mixed-use developments in Miami that signals movement toward density. Phase one opened late last year, and phase two will entail an 80-story mixed-use tower.
Just north of downtown, there’s Miami Worldcenter, a 17-million-square-foot, 27-acre complex. It’s a joint venture by multiple developers, with Boston-based Elkus Manfredi leading the master plan and designing the center’s phase one, which is anchored by a 1-million-square-foot retail podium. Phase two is a $750 million convention center and hotel.
Development isn’t only concentrated in the urban core. About two miles north of Downtown in the Wynwood neighborhood, developer Moishe Mana and Miami-based Zyscovich Architects are poised to build a 9.72-million-square-foot, 23.5-acre development that will feature as many as 3,482 residential units, a mix of retail, office, and cultural programming, as well as an extensive public “Mana Commons” that will cut through the complex’s cluster of medium-rise towers. Dubbed Mana Wynwood, it won approvals last September. More like it may be on the way: In Little Haiti, the Eastside Ridge development will replace 500 townhouses with 7.2 million square feet of mixed-use development, and another project dubbed “Magic City” (also located in Little Haiti) would see an innovation center, business incubator, housing, retail, and other art-entertainment facilities arise across a 15-acre campus.
What’s driving all of these major concentrations of development? In part, affluent young professionals across the U.S. are moving to cities seeking walkable, transit-connected neighborhoods, and developers are eager to meet that need. But there are factors unique to Miami. One is the city’s zoning: The Miami 21 code, implemented some six and half years ago, has significant parking requirements that incentivize large developments. For example, in dense high-rise areas, the code mandates 1.5 parking spaces per unit. Consequently, smaller projects struggle to meet the logistical and economic challenges of incorporating that much parking into their site. Bigger projects can more easily integrate a parking garage into their lower levels. Furthermore, if a development covers nine contiguous acres, it can qualify for a Special Area Plan, an arrangement that allows developers more flexibility in situating parking and negotiating the rules of Miami 21’s form-based code. This maximizes the development’s value. Brickell, Mana Wynwood, and the Worldcenter, as well as virtually all of Miami’s major developments, are (or have applied for) Special Area Plans.
Miami’s geography is also part of the equation. John Stuart, professor of architecture at Florida International University and executive director of its Miami Beach Urban Studios, explained how wealth from the Caribbean and Central and South America has historically flowed into Miami. “We have this gravitational pull from the south,” he said. Affluent people from Chile, Venezuela, and elsewhere come to Miami seeking “these kinds of urban experiences where they’re safe, their products are confirmed as authentic, but they’re close to their own countries….”
But the city’s geography turns from an asset to a risk when one considers the threat of extreme weather and sea-level rise. Miami Beach, which sits a mere four feet above sea level (compared to Miami’s six feet), is regularly inundated during king (high) tides and is spending nearly half a billion dollars to raise streets, install pumps, and push back the waters. Faced with such uncertainty, Stuart sees mega-developments as “just overflowing with optimism” and the belief that climate change will be remedied, ameliorated, or far enough away to not warrant significant concern in the near future.
In the shorter term, how Miami 21 and public transportation evolve may be deciding factors in shaping the city. In Wynwood, the City of Miami Planning Department is testing out a new zoning overlay that alleviates parking requirements for developments with smaller units. If Wynwood ceases to become the exception, then dense growth may not be restricted to Special Area Plan developments and the downtown urban core.
This leads to the issue of public transportation. “That’s at the core of much of what’s fragmenting the city, holding it back economically, socially, culturally,” said Stuart. “There’s very little opportunity for people who live in a neighborhood they can afford to access other neighborhoods for employment, artistic production, or other means.” Miami is in the process of funding and planning an expansion of the Metrorail, the city’s above ground heavy-rail rapid transit system. Eighty-two miles of new rail and six new lines—costing $3.6 billion—would connect the city’s burgeoning neighborhoods with each other and downtown. Complicating the situation are Uber and Lyft, whose low rates can be competitive with public transportation. Moreover, according to Fort, the prospect of driverless cars adds a new level of uncertainty to major public transportation investment.
A conversation about public transportation and mega-developments must also include the question of affordability. According to a 2016 study from the New York University Furman Center, in Miami “85 percent of recently available rental units were unaffordable to the typical renter household,” making the city the least affordable for renters among the country’s top 11 metro areas. But there are glimmers of hope: As development moves from the urban core and the waterfront to places like Wynwood, more non-luxury units may come online. Additionally, the city is already taking steps to increase affordable housing stock: A measure passed in late February would reward residential projects that feature affordable units with greater density and less required parking. However, while the downtown core and Wynwood don’t have large existing communities facing gentrification, that challenge may arise elsewhere. In other instances, density alone may deter development: Earlier this year, local opposition stopped a 1.2-million-square-foot Special Area Plan development east of Little Haiti.
For a firsthand experience, Fort recommends riding the Metrorail to survey the city—from there, you can see pockets of development (Coconut Grove, Little Havana, Brickell, Downtown) that he thinks could become medium-density nodes in a new polycentric city. He also cites neighborhoods like Edgewater, Wynwood, and the Design District that aren’t on the Metrorail but are still growing. “That’s what I think the next phase of development in Miami is,” he said, “where we look at neighborhoods and understand what’s missing” to make them mixed-use, denser, and affordable. Optimism for density, however, is just one of many factors—climate change, transportation technology, affordability, and zoning codes, to name a few—that will shape Miami in the years to come.
Turning the Tide
Facing rising sea levels and greater insurance risk, Southern Florida braces for relocations, new flood design standards, and more
This article appears in The Architect’s Newspaper’s April 2017 issue, which takes a deep dive into Florida to coincide with the upcoming AIA Conference on Architecture in Orlando (April 27 to 29).

The moon over South Florida looked like a swollen grapefruit in November, its reflection rippling off pools of ocean water that bubbled up through storm drains, crept over seawalls, and swallowed Miami streets. It was a “supermoon,” about 17,000 miles closer to Earth than usual, according to NASA, arriving just in time to supercharge the seasonal high waters known as king tides. The water made an island out of the lifeguards’ shack on Matheson Hammock Park, swept “No Wake” signs from marina harbors onto city streets, and marooned a live octopus in a parking garage along Biscayne Bay.
On days like these, it’s obvious that much of the region now home to about 7 million people began as a network of swampy canals meandering from the Everglades to the ocean. Sometimes nature conspires to remind the city of this fact, as it did in November 2016.
Lately those reminders have become more frequent. The rate of sea-level rise has tripled over the last decade, according to a recent study from the University of Miami, bringing with it more frequent coastal flooding. The U.S. Army Corps of Engineers projects that Miami-Dade County will see about 15 inches of sea-level rise by 2045. And because South Florida sits on porous limestone bedrock, saltwater is not just encroaching on coastal communities, but gurgling up from below.
Right now it’s a nuisance, but over the lifetime of a mortgage, flooding in South Florida could threaten tens of billions of dollars of real estate and upend development in the country’s 10th largest metropolitan area. Architects, planners, and developers are just beginning to overhaul the urban landscape, laying the groundwork for a sweeping transformation of building codes, municipal infrastructure, and design norms that could save the city from rising seas.
The crucial question is: Who will change that built environment? Will it be architects and city officials, safeguarding South Florida against the effects of climate change as the world’s living laboratory for so-called climate resiliency? Or is nature coming to reclaim Miami as a swampland?
South Florida’s development boom is so lucrative it seems inevitable that it will continue. Before the city was founded in 1896, however, it wasn’t clear that the mouth of the Miami River would ever be anything more than a mosquito-infested trading post—until the industrialist Henry Flagler dragged his railroad south from Palm Beach along the highest ground he could find: a coral ridge between 12 and 25 feet above sea level. The tracks reached Biscayne Bay on April 22, 1896. Three months later Miami was incorporated.
Today, Miami is a bustling, sprawling urban landscape that has been remade to suit cars, but some planners say that the same limestone ridge Flagler used could anchor climate-friendly development.
The Urban Land Institute is drafting a plan for the Arch Creek Basin, a mostly low-lying area straddling 2,800 acres and four municipalities, as well as unincorporated Dade County, around one stretch of the railroad. Primarily poor people of color, the residents of Arch Creek face a severe threat from sea-level rise—one that could eventually force them to abandon the area.
At a charette in November, designers Gustavo Sanchez-Hugalde, Max Zabala and University of Miami professor Sonia Chao presented their idea for a flood-resistant transportation hub at Northeast 125th Street. It would be transit-oriented development, dense with mixed-use buildings and affordable housing, but also with a health clinic, back-up generators and other resources that could come in handy during a disaster.
“Think of these as not just transit but resilience stations,” said Chao.
In the long run, South Florida’s scarcity of higher ground could also make its elevated areas more valuable as waters rise. That could exacerbate gentrification in minority neighborhoods with relatively high elevations like Liberty City and Little Havana.
“It’s a matter of time until investors will head for the higher land,” said James Murley, chief resilience officer for Miami-Dade County. But climate change isn’t forcing people out of their homes just yet. Asked if climate change is a driving force for gentrification in Miami, Murley is skeptical, but others are starting to look toward the future.
“Right now we’re experiencing more of the classic gentrification that comes with a growing real estate economy,” Murley said.
While the mainland mulls long-term plans to adapt to rising seas, the coastal barrier island of Miami Beach is busy building.
Planning for High Water
Over the next five years, the municipality of Miami Beach will spend $400 to $500 million on flood defenses, installing 80 new pumps, raising roads, and strengthening seawalls across the city. So far the city has funded about $200 million of that project by more than doubling stormwater fees.
A law passed last year requires the owners of buildings larger than 7,000 square feet to pay a fee if they don’t get certified as at least LEED Gold. The builders of properties that don’t get LEED certified at all get slapped with a fee equal to 5 percent of their construction costs. That could help raise money for future infrastructure investments.
Miami Beach also requires new buildings to be at least one foot above the base flood elevation of six feet above sea level. As an additional incentive for developers, the city won’t count the raised elevation of a flood-proofed site toward the project’s height limit or floor-to-area ratio.
Miami Beach environment and sustainability director Elizabeth Wheaton said the new requirements wouldn’t stunt development.
“Developers want to build here,” Wheaton said. “They’re going to do what’s required.”
The first building completed under the new elevation requirements is Jean Nouvel’s Monad Terrace, a 59-unit luxury residential tower on the waterfront in South Beach. Nouvel built Monad Terrace’s ground floor more than 11 feet above sea level, elevating all of the building’s interior spaces and its entrance high enough to ward off flooding.
Building high is an increasingly popular choice for private residences, too. The local architect Rene Gonzalez, known for his high-end modernist houses, is building four new homes in the area that are modeled on mangroves—propped up with stilts and columns for an additional layer of privacy that also affords the owner some long-term insurance against flooding. Gonzalez designed his own home on Belle Isle the same way.
“It’s a responsibility that every architect should take on,” said Gonzalez. “Building a house up is not a luxury. It’s a necessity in our current environmental climate.”
For now, however, most of that work is clustered in tony Miami Beach. In Miami-Dade County at large, where nearly half of all residents live in poverty, there are fewer options.
Because saltwater rises up through South Florida’s porous limestone bedrock, it’s not just coastal communities that are at risk. Many of the most threatened areas lie miles inland, in suburban and often low-income areas of Miami-Dade and Broward Counties that can’t afford to elevate all their homes and streets.
“It’s unavoidable that there will be relocations,” said Anthony Abbate, an architect based in Fort Lauderdale in Broward County, just to the north of Miami-Dade. “It’s a difficult conversation but I think we’re on the verge of having it. This has to be a conversation with the people, with the public.”
Miami-Dade is in the middle of a vulnerability analysis for major infrastructure, from its airport to its water system, identifying “adaptation action areas” where city planners might best focus their efforts.
“There’s a lot of work that needs to be done and it needs to be done in short order,” said Abbate.
Some of that work is already underway. The newest addition to the county’s hospital system will pioneer a flood-friendly approach in the recently incorporated town of Doral, just west of Miami International Airport. Designed by Perkins + Will, Jackson West hospital will devote most of its 27 acres to green space and a retention pond to store runoff not just from the built-up part of the site that will house the hospital, but from the developments surrounding the site. Construction is set to begin later this year and the hospital could open in 2020.
Risk and Reward
Perhaps before it faces up to the force of nature, however, South Florida may have to reckon with its runaway real estate market. Wayne Pathman, a land-use attorney and chair of Miami’s Sea Level Rise Committee, said the face of Miami’s climate crisis might not be a natural disaster, but a collapse of the insurance market.
“Flood insurance is going to be the tip of the spear,” Pathman said. “Unlike hurricanes, which are a single event that may not happen for years at a time, sea-level rise is a constant. Once it’s here, it’s here, and it’s never going to get better.”
Pathman said some of his clients with property in Miami Beach and North Beach are already seeing a 500 percent increase in their flood insurance premiums. For now, that’s manageable, he said, because they were probably underpriced in the first place.
“When that jumps as high as $50,000 over the next 10 years, which it will, that’s alarming,” he said.
Areas that today flood two or three times each year could see water in the streets every week, and banks may stop offering mortgages there. That could have ripple effects across the region, Pathman said, jeopardizing tourism dollars and property-tax revenue that Miami-Dade and Broward counties will need to fund new climate-resilient infrastructure.
“Those are our only two industries here in South Florida,” Pathman said. “If we don’t start dealing with the insurance risk, all the ideas we come up with for future infrastructure will be cost-prohibitive because we won’t have any money.”
Reinaldo Borges, an architect who sits on the sea-level rise committee with Pathman, said the luxury houses and museums already built to deal with higher seas show climate-resilient design can provide a return on investment.
“If you design correctly,” he said, “you shouldn’t be worried about insurance risk.”
Borges has a checklist for clients who are looking to invest in the future of Miami real estate—not just flip property for a profit. It includes elevating building mechanical systems, installing hurricane-proof windows, and planning for severe floods.
“For a building like that, all you have to do before a storm is bring your pool chairs inside,” he said.
Climate-proofing one building may be a straightforward design problem. Saving a metro region of 7 million is something else.
Borges came to Miami when he was six years old, brought from Cuba by parents who sought a better life for their children. Today he has two daughters, ages 23 and 29, and he has the same hope for them.
“When you’ve got political leadership in denial, these are challenges I’m concerned about,” said Borges. “This is a world-class city, but people are starting to ask if this is the place they really want to invest.”
In terms of cities and climate change, Miami Beach is the biggest canary in the coal mine. At approximately four feet above sea level, this 19-square-mile strip of artificial and natural islands faces frequent flooding during storms and high tides. (Last September’s king tide—a colloquial term for high tide—reached 2.2 feet.)
The city is aggressively fighting the watery onslaught: Over the next five years, Miami Beach will spend $400 to $500 million in anti-flooding defenses that include pumps, raised roads, and seawalls.
This is money well spent. The Miami area sits on limestone that absorbs floodwaters and can force the deluge back to the surface, making flood control a special challenge. Still, environmental concerns aren’t stopping new developments across Miami. The economic timeframe for developers (and the residents buying and renting) remains relatively short compared to the long-term threat.
In addition to flooding, another, more insidious threat looms: Miami maintains its Biscayne Aquifer by channeling freshwater from Lake Okeechobee to push back against saltwater intrusion, which means the region may have to choose between flooding or drinking salt water. By 2060, some estimates place sea-level rise at three feet. Further down the line, questions of how federal and private insurers will provide flood coverage —and how eager banks will be to issue mortgages—may also arise.
21 But Sure Not Done
Eight years in, how has Miami’s form-based code primed the city for unprecedented growth?
Over the past 15 to 20 years, Miami has become a city of condo dwellers, a shift that transformed the cityscape’s pattern of suburban sprawl and single family houses under palm trees to coastline-following mountain ranges of luxury towers that reach for the sky. In the 1980s, the Golden Girls lived in a house, but when the Kardashians came to town, they chose a condo in South Beach.
As more people flooded into Miami’s urban areas, the city took action to help new buildings and infrastructure adapt to the urban shift. In 2008, Miami approved Miami 21, the first New Urbanist zoning code to be applied to a large, preexisting city. The form-based code was applied to a citywide rezoning and was a huge test for an urban planning movement that is more common in small towns like Seaside, Florida, the famous Truman Show locale. The code, enacted as the growing city was quickly running out of land, has led to a reassessment of how Miami works, and has prompted a more logical regeneration of the city’s urban core.
New and old Miamians are moving into towers in areas around Downtown, like Edgewater, Brickell, and Midtown. Buildings are being built for people, not cars. Street frontages are activated. Parking garages are hidden.
Traffic, however, is getting worse. Mobility suffers with inadequate mass transit, yet people keep coming as international appeal remains as high as ever. As Miami’s density increases, the city needs more effective mass transit. Miami’s growth is reaching a breaking point that infrastructure, backed by new policy, is designed to address.
MiamiCentral, a massive new train station and mixed-use mega project, is being built in the center of Downtown Miami where an older train station, demolished half a century ago, once stood. The new station, with residential, commercial, and retail space, started as a terminal for an intra-metropolitan area high-speed rail line that in a few years will take passengers to Orlando in about three hours. MiamiCentral will also be the terminus for a new spur of Greater Miami’s commuter rail system, Tri-Rail, which will bring commuter rail into downtown for the first time.
Other new transit improvements are being considered across the city and the greater metropolitan area, including an expanded trolley bus system, a westward rail connection, a northeast light-rail corridor, and a light-rail line connecting to Miami Beach across Biscayne Bay.
Although one of Miami’s newer claims to fame, or at least notoriety, is high-design parking garages, excessive parking requirements meant for a world where everyone has a car are outdated. Parking is a persistent issue with Miami 21, as standard parking minimums are unchanged from the previous auto-oriented zoning code. The requirement to build 1.5 parking spaces per unit means that infill construction on Miami’s standard-sized 50-foot lots is unnecessarily costly and physically impractical, if not downright impossible, once driveways are considered.
Last October, the city passed a new rule that allows up to 50 percent parking reductions in transit-accessible areas with a 100 percent reduction for buildings under 10,000 square feet. The changes aim to encourage the small-scale infill urbanism that so often forms the basic building blocks of successful older cities. The main advocate behind the reduction, developer Andrew Frey, is building a small infill development without parking in Little Havana that he hopes will inspire others.
As new neighborhoods grow, special zoning districts are being created to suit them. In Wynwood, Miami’s famed mural district, the existing industrial zoning became increasingly unsuitable for a creative neighborhood where people live, work, and go out. A requirement for live-work housing created large and expensive units, not the smaller, more affordable housing that locals desired. Street conditions were basic and not conducive to the pedestrian-driven neighborhood. Last year, the Wynwood Business Improvement District commissioned a master plan that became the Wynwood Neighborhood Revitalization District zoning overlay in July 2015. The code’s standards weren’t adequate for the evolving neighborhood, but a provision allows for these kinds of overlays.
Since the implementation of Miami 21, neighborhood groups and developers have created overlays like the Wynwood Neighborhood Revitalization Districts and Special Area Plans (a similar tool developers use when creating a large assemblage) to create neighborhood-appropriate zoning. Miami 21’s revisions at the neighborhood scale demonstrate both its flexibility and imperfections, but it clearly creates a nuanced framework for the city that’s simultaneously logical citywide and hyperlocal to the human scale.
