Central Park is not only the major recreational facility of Manhattan but also the record of its progress: a taxidermic preservation of nature that exhibits forever the drama of culture outdistancing nature. Like the [Manhattan] Grid, it is a colossal leap of faith; the contrast it describes – between the built and the unbuilt – hardly exists at the time of its creation.

– Rem Koolhaas, Delirious New York1

.

Koolhaas presents one of the challenges core to Central Park’s construction: the tension between natural and manmade, urban and rural. What sets this park apart from most other parks is its yearning to seemingly become something that it clearly is not: natural. Many other pocket parks in this city incorporate existing topography and trees into their design – yet they are smaller. And from the confines of their interior, the sights and sounds of the city are hard to escape. Central Park succeeds in permitting its visitor to make-believe, at least momentarily, that they have left the city and are immersed in the countryside. The original park contained, for instance, a sheep pasture and barn, a nature preserve called “The Ramble,” and a dairy for urban mothers to buy fresh milk.

The scale of Central Park and the engineering that went into its creation is not unprecedented – architects and engineers have completed far larger infrastructure projects. The New York City watershed, for instance, catches all the rainfall within a 2,000 square mile area, stores this water in 19 reservoirs, and then transports this water up to 150 miles in underground pipes that serve nine million people.2 Central Park, by comparison, was built by some of the same engineers but is a mere three-square-miles of “improved” wilderness. However, what is surprising is the degree to which Central Park’s landscape features seem natural, as if land speculators and developers had chanced upon the park and left it as untouched as they had found it, except framed on four sides by the city grid (figure 5). So successful is this intervention that there is often the popular misconception that it is natural. This Huffington Post article, for instance: “I know that it may come as a shock to some, but New York’s Central Park is not an act of God. It might seem that way, especially in the woodlands, which appear so authentically, well, natural.”3

In the 1857 text entitled “The Plan for the Park,” the project’s landscape architect, Frederick Law Olmsted (b.1822-d.1903), writes that it “seems desirable to interfere with its easy, undulating outlines, and picturesque, rocky scenery as little as possible, and, on the other hand, to endeavor rapidly and by every legitimate means, to increase and judiciously develop these particularly individual and characteristic sources of landscape effects.”4 Olmsted’s claim is a good place to start because it expresses a paradox central to the design. Olmsted’s project “interferes” with the landscape “as little as possible” simultaneously with large-scale efforts to move soil, blast rock, and plant trees that employed – at the height of work – some 4,000 men.5 Around five million cubic feet of rock and soil were blasted and removed from the park. Rem Koolhaas interprets this quote from Olmsted as follows: “If Central Park can be read as an operation of preservation, it is, even more, a series of manipulations and transformations performed on the nature ‘saved’ by its designers.”6

How can we reconcile these two seemingly opposed tendencies in Central Park – natural vs. manmade – when almost all manmade features are disguised as natural? I propose that we can better understand the park by dispensing with the pretense that it is in any way natural.

Central Park presents an unusually refined interpretation of nature. Of the approximately 20,000 trees of 175 species, solidly 60% are non-native to New York.7 Of the seven lakes contained within the park, none are natural to the terrain and are mostly the result of damning existing streams. Of the paths, trails, and roads winding through the park – with curves to match the contours of hills and valleys – none are original, nor do they correspond to pre-development dirt roads and Lenape Indian trails.8

Before work began in 1857, the pre-development topography was insufficient for use as a public park. The Manhattan grid – comprising some 2,000 plus city blocks each measuring exactly 200 feet wide – implies a flat terrain and originally made no accommodations for interfering rivers, hills, or marshes. Looking at a street map of the island, one might be surprised to learn that the terrain rises and falls the length of the island from zero feet at sea level to ~250 feet at its highest peak (figures 4 and 16).9 The name “Manhattan” is a Lenape Indian word that means “Island of Many Hills.”10 Yet, despite the variety of sites planners could have chosen from, the park’s rectangular boundaries were not determined by the availability of topographic features appropriate for a park.

.

Figure 4. British Headquarters Map of Manhattan Island from c.1789. Only the shaded pink section at top of island is developed at city-level density. The rest consists of rolling hills, forest, and farmland that inspired Henry Hudson, the first European who “discovered” the island in 1609, to remark that: “The land is the finest for cultivation that I ever in my life set foot upon.”11

.

Instead of topography, three main factors determined the location: First, planners needed to choose a site close to the expanding city yet far enough away that the land could be acquired cheaply and without displacing large numbers of residents. Second, the city’s population had grown 160% in the twenty years from 1840 to 1860,12 and the city’s existing Croton reservoir (then located in the exact center of the proposed park) was insufficient. The city needed an expanded reservoir; the most convenient location on Manhattan Island for this reservoir was next to the existing one. The otherwise purely practical infrastructure of water supply could thus become a landscape feature.13 Third, the city planned to offset the approximately five-million-dollar price tag of land acquisition and construction through corresponding increases in the taxable property values of land adjacent the park. The architects also went so far as to suggest “a toll of three cents on visitors coming on foot, and six cents for all others” collected on visitors to fund park maintenance and offset construction costs. (This was never implemented.)14 Olmsted also writes:

.

Land immediately about the Park, the frontage on it being seven miles in length, instead of taking the course anticipated by those opposed to the policy of the Commission, has advanced in value at the rate of two hundred per cent per annum. […] It is universally admitted, however, that the cost, including that of the original off-hand common sense blunders, has been long since much more than compensated by the additional capital drawn to the city through the influence of the Park.15

.

The park’s location might be strengthened by the simple fact that a linear or smaller park along the waterfront would have fewer miles of frontage of taxable properties adjacent to the park. For instance, locating just one side Central Park along the Hudson and East River (instead of the island’s center) would result in 2.5 miles fewer of abutting properties. Within the following decades, the properties in the Upper East and Upper West Side that overlook the park became (and remain) among the most expensive in the city. This method of development – sacrificing a fraction of the land for park use so as to increase the monetary value of the adjoining lands – was common in New York City (e.g., Gramercy Park) and particularly in London’s fashionable West End and Hyde Park neighborhoods.16 What makes Central Park different, though, is the unprecedented scale of this investment to boost civic pride and to increase property taxes.

The incongruity between the park’s outline and the topography is also illustrated by the fact that the park’s northern boundary (originally at 106th street) would require blasting through a one hundred foot high solid-rock mountain to make way for the perimeter street.

.

Given these priorities – real estate and infrastructure interests over aesthetics – the choice of location was not ideal (figure 5). The rough terrain was mostly barren of trees and was a mosquito-laden wetland. (More readily converted and forested terrain was originally proposed along the East River in the vicinity of Roosevelt University.) Before beginning the architect’s work of planting trees and building scenic garden features, the first major task was to prepare the land and make it suitable for public use. To that effect, Olmsted contracted the engineer (and later military coronel) George E. Waring to drain the swamp. Waring directed 400 men to construct some 105,000 linear feet (32 kilometers) of drainpipes over two years (figure 8).17 His military-style approach toward clearing the park followed him into later life when he became New York City’s sanitation commissioner. As commissioner, he required all his street cleaners to wear white pith helmets (identical to those worn by European colonists in Africa) and then declared the war on filth. Given his interest in sanitation and dislike of dirt, his answer to the park commissioners’ question is revealing:

.

Commission’s Question: “To what degree shall the park be drained?”
Waring’s Answer: “Totally.”
Q: “By what form of drains?”
A: “Earthenware, of varying calibers.”
Q: “At what depth?”
A: “Three feet in open glades, four feet in forested areas.”
Q: “For best economy, by contract or days’ work?”
A: By days’ work because of the endlessly varied conditions requiring uncommon on-site super vision.”18

All the land visible here is now buried beneath the reservoir.

.

Another requirement asked of the planners was to incorporate a new reservoir into the park (figures 6-7 show terrain now flooded beneath reservoir). The existing stone reservoir and Croton Aqueduct, completed 1842, were no longer sufficient19 despite Walt Whitman’s claim that: “Ages after ages these Croton works will last, for they are most substantial than the old Roman aqueducts.”20 To augment the Croton’s capacity, the new reservoirs combined covered approximately 20% of the park’s surface area over terrain that otherwise would have become parkland. Before Olmsted had even submitted his plan in 1857, the engineer Egbert L. Viele, who had been surveying the parkland since 1853,21 had decided on placing this reservoir on a natural depression in the land, to be augmented by an earthen embankment around the perimeter. Olmsted’s final proposal follows the contours of Viele’s proposed reservoir exactly – illustrating the degree to which engineering needs dictated the landscape architect’s choices.

On the left is 59th Street, 5th Avenue is at bottom, and 8th Avenue (i.e. Central Park West) is at top. This map only illustrates the paths of future carriage roads within the park – that is, the thick white lines that wind through the landscape. Red lines indicate the buried clay pipes that drain water from the marshy soil – and many continue to do so today. Shaded gray areas correspond to areas to be raised with dirt fill. The shaded blotches are for preserved boulders protruding above ground. The slightly off-kilter rectangle in center is for the area drained to create the Central Park Mall – the only geometrically symmetrical part of the park.

.

Although the park was extensively surveyed and re-landscaped there was, nonetheless, an attempt to appear rustic and unkempt. The architect, Calvert Vaux, blanketed the park in little pavilions and bridges made from unpolished and rustic wood with bark still on the beams – a nineteenth-century re-reading of the primitive hut.22 The passage from the southern to the northern reaches of the park was also a parable in the march of civilization and progress. By this time, the city was advancing northward up the island from its historic center in Lower Manhattan (figure 9). Within forty years, the island would be completely built-up. With this recognition of urban sprawl, Olmsted possibly named the park’s 16 original entrances to reflect the city’s movement and types of people living in New York. In order from south to north, the names are as follows: Artisan’s Gate, Merchant’s Gate, Scholar’s Gate, Woman’s Gate, Inventor’s Gate, Miner’s Gate, Mariner’s Gate, Engineer’s Gate, Gate of All Saints, Woodman’s Gate, Boy’s Gate, Girl’s Gate, Stranger’s Gate, Warrior’s Gate, Farmer’s Gate and Pioneer’s Gate. This list almost reads as a list of social classes in increasing order of proximity to raw nature.23 The design features also evolve over distance. The southern reaches (also the busiest section due to the proximity to the city center) was built first and included more pruned botanic features, rectangular parterres of trees, and the proposed flower garden. Olmsted thought it appropriate to leave the northern reaches of the park as wooded as possible with a c.1812 fortress left standing atop a mountain as a picturesque ruin in the style of English garden follies. The northern reaches (also surrounded mostly by farmland at this time) were intentionally more heavily forested, had fewer of the park’s signature bridges, retained the park’s largest rock escarpment, and for the first few decades of its life contained no statues, monuments, or plaques commemorating important people. By contrast, about two dozen monuments to Western Civilization’s great cultural and political leaders (all male) were concentrated in the south: William Shakespeare (installed 1872), Thomas Moore (1879), Alexander Hamilton (1880), Beethoven (1884), Columbus (1894), etc.24 Paradoxically, while the south may appear more refined and cultivated than the north, the pre- development terrains in both sections were equally crafted and manipulated. There is, here, the illusion of moving north toward nature, instead of the reality.

At this stage, we might arrive at a better understanding by shifting the descriptive language. Perhaps we should describe the park not in terms of nature or landscape – given that considerations of the natural were not foremost in the design. We might do better to describe the park in terms of infrastructure, engineering, movement, and social class. Indeed, one of the strengths of Olmsted’s proposal – and one of the reasons he won out of the 33 designs submitted – was his decision to separate the park by four different social classes and speeds of movement (figures 10 and 11), each of which corresponded to a width of road and minimum permitted vehicle turning radius (color-coded in figure 12).25 This detailed plan for road separation and drainage were finished before the architects had even begun working on planting diagrams or selecting which species of trees would make for the most varied landscape composition. There were four classes of segregated roads. First, because of the park’s length, size, and location, there would be many vehicles passing through the park, not for leisure, but simply to pass from one side of the park to the other as fast as possible. For these vehicles, the engineers planned four buried transverse roads with entirely separate right-of-way. These straight and wide roads at no point intersected other types of traffic and were entirely below grade level. Second, there were carriage roads for slightly slower carriage traffic within the park. While the relatively straight transverse roads were for practical through-traffic, these carriage roads were for leisure. Third, the next highest speed consisted of a narrower and more curving path than the carriage roads, gravel paths for horseback riders. Horseback riding was a popular leisure and sporting activity – these roads are now largely used for joggers who move faster than pedestrians but slower than vehicles. Fourth, the most ubiquitous road type of all consisted of unpaved footpaths for pedestrians on foot only. With the help of bridges and tunnels (figure 11), at no point did these four systems of conveyance intersect, leading Olmsted to claim: “By this means it was made possible, even for the most timid and nervous, to go on foot to any district of the Park designed to be visited, without crossing a line of wheels on the same level, and consequently, without occasion for anxiety and hesitation.”26

Incidentally, these separate and unequal paths also corresponded to different social classes. The wealthiest individuals – those who could afford a carriage, horse, and driver – would implicitly have exclusive use of the carriage roads, while horseback riders had their separate right of way, and service vehicles were segregated below grade. The rest of the public and working classes were restricted to the footpaths, where security guards patrolled the park and prohibited them from loitering, picking flowers, picnicking, or forming large groups. Elizabeth Blackmar and Roy Rozenzweig write: “In the decade after the opening, more than half of those visiting the park arrived in carriages (which less than 5 percent of the city’s population could afford to own, and each day there were elaborate carriage parades in the late afternoon.”27 Yet, disproportionate design considerations and park surface area seems to be given to this minority of users on carriages. We should return here to the fact that city leaders intended this park to boost property values and taxes on the wealthy residents who lived adjacent to the park. It is only natural, then, that the park design should reflect their interests and preferences.

The blue road corresponds to the horseback trail, now jogging path. After starting at the 59th Street entrance and passing through manmade forests, valleys, and tunnels, horseback riders’ visual experience culminated as they circled this manmade reservoir.

.

These maps of the park – color coded by road type – can help us begin to unravel the degree to which the current landscape is manmade. At first glance, the smooth passage of roads and their organic contours may seem effortless, as if they were laid out along existing roads with regards to existing topography. By separating the different grades of traffic by color (figure 14) and upon closer examination, there is a complex and extensive hidden infrastructure beneath these natural appearances (figure 13).

.

Figure 16. 1811 Commissioners’ Plan

.

These maps also reveal a park that is not separate from or opposite to the city, but instead a continuation of the city. A glance at a map of Manhattan reveals two seemingly different philosophies of urbanism, as imprinted through the laying of road networks. Most of the island is covered in the orthogonal 1811 grid (figure 16). This grid gives no consideration to topography, nature, or aesthetics. And then, there is the three square mile area of Central Park with winding and seemingly organic roads. The absence of symmetry and straight lines might lead one to conclude that the park reflects an attempt to harmonize with nature. Existing popular literature commonly situates this park as a reaction to the grid’s perceived faults and excesses. Upon closer examination, this park’s near obsessive attention to detail, its concern with segregated movement, and its reliance on complex (but hidden) infrastructure reveal the park to be a continuation of the 1811 grid’s interest in real estate, property values, and engineering, more than it is a prosaic and romantic reaction to excessive urban growth. This infrastructure is also wrapped up in a coded message about the progress of civilization. The passage from cultivated south to rugged north can read as a condensed representation of the passage from the center of civilization to its undeveloped edges. One should also keep in mind that simultaneous to the construction of Central Park, engineers and developers were at work on the other side of the country clearing the American West for development. Within the following decades, the extent of farmed land would creep westwards on former Indian soil, generally following the paths of railroads toward California. Does the design of Central Park mirror 1860s American society’s belief in the civilizing power of science and technology to tame the wilderness? Alternatively, is Central Park’s design just a matter-of-fact effort to boost the city’s tax revenues, with no moral agenda intentionally encoded in the park design? Such questions might be impossible to answer, given the lack of conclusive evidence.

Now is the time to return to the question we started with: How can we reconcile these two seemingly opposed tendencies – natural vs. manmade? I posit that by describing Central Park in the language of infrastructure and real estate – instead of nature and aesthetics – we can arrive at a more accurate assessment of the park’s origins, objectives, and construction process. Seemingly, the only way to adapt this ill-suited site into a park that fulfilled the nineteenth-century definition of the picturesque was through public works that, upon their completion, effaced almost all traces of the people, trees, and landscape that existed before. The engineering here succeeds insofar as it is invisible and functions as if no manmade intervention had ever occurred. While at work, Olmsted made this prediction on the future of Manhattan Island:

.

The time will come when New York will be built up, when all the grading and filling will be done, and when the picturesquely-varied rock formations of the Island will have been converted into formations for rows of monotonous straight streets, and piles of erect buildings. There will be no suggestion left of its present varied surface, with the single exception of the few acres contained in the Park.28

.

The park is an architectural contradiction. On the one hand, its rock formations, hills, and valleys look to a pre-developed and rugged Manhattan in the public imagination, a landscape more fictive than real. On the other hand, the park’s very presence is a testament to the power of real estate interests, engineers, and the water supply board in shaping the city. This tension underlies the landscape features now almost universally praised for their vision, beauty, and harmony.

However, Olmsted describes in writing how the terrain should evolve from smooth to rough during the passage north; it follows for naming conventions to reflect this shift.

Architecture of Exclusion in Manhattan Chinatown

Canal & Mott Streets

In 1882, the Chinese Exclusion Act restricted Chinese immigration to the US, prohibited Chinese females from immigrating on grounds of prostitution, and revoked the citizenship of any US citizen who married a Chinese male. The consequences of this xenophobic legislation led Chinese immigrants to flee racial violence in the American West and to settle in Manhattan’s Chinatown. With a population now of around 50 thousand (2010 US Census), this remains the largest ethnically Chinese enclave in the Western Hemisphere.

Doyers Street – Barbershop Row

Thanks to New York’s geographic location as a port city with high industrial employment and easy connections to the American interior, this city became the primary point of entry for waves of immigrant groups in the nineteenth-century: Irish, Germans, Italians, and Eastern Europeans. What makes the Chinese different, though, is the survival and resilience of the immigrant community they created. Other immigrant groups – namely the Germans and Irish – converged around large neighborhoods and surrounded themselves with familiar language and businesses. Of these enclaves, all have since disappeared as the children of these first-generation immigrants successfully assimilated into American society, earned higher incomes than their parents, and therefore chose to disperse to non-immigrant neighborhoods with better housing stock and schools. Yet, the Chinese remained.

The resilience of this community results from a confluence of factors: cultural, geographic, and (most of all) racial. Of innumerable immigrant groups to the US, the Chinese were among the only to have the most restrictive laws placed on their immigration. This stigma drove them toward three types of low-skilled manual labor – with which white Americans still deeply associate with the Chinese – laundries, restaurants, and garment manufacturing. Like the Chinese, other groups – particularly Irish-immigrant females – began working in these professions, but they soon climbed the social ladder.

Mosco & Mulberry All

As an architectural historian, I am fascinated about how this political and racial agenda of exclusion is imprinted in the built environment of Chinatown. To present this neighborhood’s geography: For most of its history, Chinatown was bordered to the north by Canal Street, to the east by Bowery, and to the South and West by the city’s federal courthouse and jail. The center of this community lies on the low wetland above a filled-in and polluted lake, called the Collect Pond. Historically, this area contained the city’s worst housing stock, was home to the city’s first tenement building (65 Mott Street), and was the epicenter for waterborne cholera during the epidemics of 1832 (~3,000 deaths) and again in 1866 (1,137 deaths). The city’s first slum clearance project was also in Chinatown, to create what is now present-day Columbus Park.

Race-based policies of exclusion can take different forms in the built-environment. The quality of street cleaning and the frequency of street closures are a place to start. Some of the city’s dirtiest sidewalks and streets are consistently located within Chinatown – as well as some of the most crowded with street vendors (particularly Mulberry and Mott Street). Yet, as these streets continue northward above Canal Street, their character markedly changes. The sections of Mulberry Street in Chinatown are unkempt and always open to traffic and truck deliveries.

The street sections immediately north (in the enclave of Little Italy) are frequently cleaned and closed for traffic most of the year to create a car -free pedestrian mall bordered by Italian restaurants. These policies continue when examining the proximity of Chinatown to centers of political power and criminal justice. Since 1838, the city’s central prison (named the Tombs because of its foreboding appearance and damp interior) is located just adjacent to Chinatown. The Fifth Police Precinct is also located at the center of this community at 19 Elizabeth Street.

Bayard & Mulberry Grocery

Yet, although this neighborhood was ranked 58th safest out of the city’s 69 patrol areas and has a below-average crime rate, the incarceration rate of 449 per 100,000 people is slightly higher than the city average of 443 per 100,000 and significantly higher than neighborhoods immediately adjacent – like SoHo – that have a rate well below 100 per 100,000. NYC Open Data also reveals this neighborhood to be targeted for certain – perhaps race-specific and generally non-violent crimes – like gambling and forgery. Or, the only financial institution to face criminal charges after the 2008 financial crisis was NYC Chinatown’s family-owned Abacus Federal Savings Bank – on allegations of mortgage fraud later found false in court by a 12-0 jury decision in favor of Abacus.

When it comes to tourism, Americans seem to have a paradoxical relationship with Chinatown’s “oriental” culture and cuisine. On the hand, there is a proclaimed love of Chinese cuisine and art, as evidenced by the profusion of Chinese-themed restaurants for tourists in Chinatown, or as evidenced by the phenomenon in art history for western artists (and particularly French Impressionists) to incorporate decorative motifs from East Asian woodcuts and ceramics into their work. There is simultaneously exclusion of the people – from the society who created this food and art – from political power and social mobility. Still today, Americans seem to want competitively priced Chinese products without suffering the presence of the foreigners who produced these products.

Forsyth & Delancey Grocery

Let us clarify one thing: the division in Chinatown is by no means “apartheid.” It is perhaps a division more subtle and difficult to notice. It expresses the kind of unequal treatment – antiquated housing, crowded conditions, and municipal apathy – that face many immigrant groups in the US. What we see in Chinatown is something altogether more complicated – as this neighborhood is also active in the process of gentrification with rising rents pushing out older Chinese businesses. If and when Chinese immigrants become fully integrated into American society, to what extent should the architectural fabric of this Chinese enclave be preserved, considering that its very existence is possibly a marker of race-based exclusion and the century-long challenge of the Chinese in America?

Geography of Incarceration

 

.

Between 1 January 2013 and 31 December 2017, the New York Police Department (NYPD) made 102,992 arrests for the possession, sale, and/or use of marijuana. 1 While only 25.5% of New Yorkers are Black, 67.5% of marijuana arrests are of Blacks. Similarly, 18 out of 20 marijuana arrests are of male individuals, even though only 13 out of 20 marijuana users are male. 2 Males more than females and Blacks more than others are arrested for marijuana. While these two aspects of the “War on Drugs” are widely known, less discussed is the clustering of marijuana arrests in specific hotspots.

These arrests are disproportionately of Black males between the ages of 18-44 from low-income communities, even though this demographic represents less than 10% of the city’s population. Why should this matter? Arresting individuals for using a relatively harmless and non-addictive drug is expensive for the taxpayer. According to the Drug Policy Alliance, the city spent $75 million on marijuana arrests and prosecution per year 4 – money that could have been put to more effective use on education, awareness, etc. This policy also unfairly targets the individuals to whom the consequences of arrest, incarceration, and bail are highest.
The common argument, and the grounds on which marijuana was initially made illegal, is that marijuana is a “gateway drug.” Marijuana supposedly introduces and later encourages individuals to experiment with more dangerous and addictive substances. Whether or not this is true, the arrest and punishment of individuals for marijuana may incur the equal risk of serving as a “gateway crime” to the legal system.

Below are three maps of neighborhood “hotspots” for marijuana arrests. The income of every block is indicated on a red to green color scale from low to high. Population of Latinos and Blacks per square mile is also indicated; unsurprisingly, these groups cluster in low-income neighborhoods. On this base map is the geo-referenced address of every arrest for marijuana possession or sale from 2013 to 2017. Of particular note is the tendency for marijuana arrests to occur in low-income neighborhoods. For instance, Manhattan’s 96th Street represents an income divide between the wealthy Upper East Side and the comparatively poorer Harlem. Drawing a “thin blue line” down 96th, we also identify an unspoken policing boundary. Marijuana arrests are significantly less likely to happen in the majority white neighborhood south of 96th than in the majority black neighborhood north, even though both neighborhoods are of comparable population density. According to the UCLA: “Despite roughly equal usage rates, Blacks are 3.73 times more likely than whites to be arrested for marijuana.” 5 Similarly, the wealthy and majority white neighborhood of Riverdale in the Bronx has few arrests in comparison to the poorer and majority black West Bronx, even though these two neighborhoods are less than mile apart.

Research Methodology and Sources

.

Note that on the above map, there are numerous low-income neighborhoods without any drug arrests. This is largely because these areas have little to no population, such as Central Park or La Guardia Airport.

This project was assembled entirely publicly-available data. I began by downloading anonymized microdata on the race, crime, gender, and age of every individual arrested by NYPD, as well as the address where this individual was arrested. Of the approximately 1.7 million arrests in this spreadsheet, I filtered out the marijuana crimes. The colored basemap indicating per capita income and race by city block is extracted from Tableau Public, the mapping software I use. The infographics presented above can be explored or downloaded at this link. Arrest data is from NYC Open Data at this link.

Introduction

.

There is an ongoing debate between in New York City between developers seeking to rebuild the city in the image of global capitalism and preservationists seeking to slow the rate of change and protect the appearance of the city’s many and distinct neighborhoods. This debate plays out every year in the hundreds of buildings  and structures that are added to (or rejected from) the Landmarks Preservation Commission’s running list of landmarks (LPC). Once added, landmarked buildings cannot be modified without first seeking approval from the city. To date, there is no process for de-listing a landmark once added – unless (sometimes intentional) decay by neglect requires demolition. This aspect of preservation is particularly contentious for developers because the legal barriers of preservation law are permanent, binding, and affect all current occupants and future owners.

Historic preservationists are the arbiters of taste. The sites they preserve will become the aesthetic lens through which future generations will appreciate the city’s past. The sites they do not preserve or neglect to protect from demolition will be lost to history – no longer a living testimony to vanished builders, architects, and immigrants. On the individual scale, preservation is about protecting structures of value. On the larger scale, preservation is part of a larger historical debate: Which aspects of the past are worth preserving? And what kinds of narratives can historians tell about cities, based on the material evidence that survives?

In this debate, there are many factors driving preservation: fear of losing heritage, fear of change, well-intentioned activists in the spirit of Jane Jacobs and NIMBYism, or concerned scholars and public servants who see something unique in the sites they add. The objective of this paper is to assess arguments made in favor of or against historic preservation through an analysis of publicly-available landmark records from the New York City Open Data website. We identified two datasets, both containing ~130,000 spreadsheet entries for every single LPC listing. The first dataset is entitled “Individual Landmarks” 1 and describes the date entered in the LPC database, the address, lot-size, the geographical coordinates of every single structure, etc. The second dataset is entitled “LPC Individual Landmark and Historic District Building Database” 2  and includes the construction date, original use, style, and address of all structures. We downloaded these two datasets as .csv files, imported them into mapping software called Tableau Public, merged them into a single file, and then conducted a data analysis – the results of which inform all the statistics presented here and drive the conclusions drawn in the following pages.

From this research methodology, we identify heretofore hidden trends in historic preservation. Firstly, we identify contextual preservation and historic districts as a means to protect the human scale of neighborhoods. Secondly, we identify a marked and potentially unjustifiable preference of preservationists for protecting pre-1945 structures. And thirdly, our data hints at the strength of market forces and developers in shaping the scope of preservation.

Case Study One:

Distribution of Landmarks over the Five Boroughs

.

Above is a tree map of the distribution of the 128,594 landmarks across the five boroughs. This includes both buildings and non-buildings, like street lamps, parks, statues, etc. The size of each rectangle corresponds to the number landmarks within one historic district. Or, in the case of the largest rectangle for each borough, the box represents the number of individual landmarks outside historic districts for that borough. The size of the box reflects the number of buildings within each district – the larger the box, the more buildings within that category. Each historic district is color-coded by borough and grouped alongside all the other districts within that borough. Manhattan. Brooklyn. Queens. Bronx. Staten Island.

.

125,594 records above

.

At first glance, we notice several trends. The densities and locations of preserved districts do not correspond to the most densely populated areas. For instance, Manhattan, with population only 19.3% of the citywide total, 3 has 30.46% of the landmarks. By comparison, Staten Island, with only 5.55% of the population, has 16.24% of landmarks – the greatest per capita number for all five boroughs. Or, the Bronx with 17.06% of people has only 5.36% – the lowest per capita. Given that the land area of Bronx (42.47 mi²) is comparable to Staten Island (58.69 mi²), and given that their histories are equally rich, then does the Bronx objectively have fewer landmarks worth preserving? Or, do preservation trends follow patterns of economics and race – with economically advantaged neighborhoods having stronger legal and political leverage to maintain and restore the appearance of their architectural heritage?

.

Manhattan Brooklyn Queens Bronx Staten Island
% of NYC population in this borough 19.30% 30.72 27.36 17.06 5.55
% of NYC landmarks in this borough 30.46% 25.65 21.98 5.36 16.24

.

Historic preservation does not operate off of a tabula rasa with objective standards and processes for listing, despite appearances to the contrary. There is an undeniably spatial pattern to urban growth and income inequality with a city segregated into districts by age of construction, race, and income. Historic preservation may operate on this unequal economic fabric.

Case Study Two:

Contextual preservation?

.

One of the most common criticisms of the preservation movement is that it limits economic development by preventing the demolition of older structures and their replacement with larger and more desirable new ones. Additionally, historic preservation is linked to a lengthy (and expensive) approvals process that developers must pass through. A committee of historians reviews each application and suggests revisions to ensure that new development is either a) “contextually” respectful of its neighbors if involving construction on vacant land or b) preserved the existing fabric if involving rehabilitation of an already landmarked building. 4

Developers often claim that historic preservation discourages development and reduces the potential of land to be profitably developed. To support this, developers will acknowledge that there doubtless are structures worth preserving, but that the same legal protections extended to genuinely historic structures are also extended to their less-significant neighbors. This criticism of preservation applies to vacant parcels within historic districts or more modern buildings that are surrounded by historic ones. Our data does not support this claim.

Within the city’s unequal fabric with pockets of concentrated, wealth, poverty, and history, we identify three general categories of protected buildings. First, there are individual landmarks, such as bridges, large railroad stations, statues, or street furniture. While aesthetically and historically important, these individual sites are rarely adjacent to other landmarks. Also, new development can occur adjacent with few restrictions on zoning. No approval from the LPC is necessary – only construction permits and variances as needed. The case for preserving these structures is strong, as application for each was individually made and individually approved on a case-by-case basis by city government and often with approval from the landowner at time of designation. Grand Central Station and Saint Patrick’s Cathedral are two examples. These structures, on account of their height, size, or appearance are genuine landmarks and place-makers in defining neighborhood identity.

Second, there are historic districts, comprising continuous stretches of smaller buildings. This includes structures of various age, use, function, and size. Preservation here is justified on the grounds that 1) the individual structures are historically unique or “significant” and 2) the relationships between these structures and the human-level streetscape they form are worth preserving. Here zoning and use restrictions may be restrictive as the majority of historic districts fall within mostly residential neighborhoods. Height limits are also stricter with the frequent stipulation that new additions must be setback from the main façade line and under one story. From the text of the 2018 city-wide zoning ordinance, zoning aims: “to protect the character of certain designated areas of historic and architectural interest, where the scale of building development is important, by limitations on the height of buildings.” 5

.

.

Third, there are contributing and vacant parcels within these historic districts. The protections applied to category two buildings are extended to category three on the grounds that development on these less important sites will affect the quality and aesthetics of adjacent structures. The best example of this kind of contextual preservation comes in the form of a series of structures. Most may retain their original appearance, but a few interspersed between post-date the neighborhood’s age, are built in a different style, or suffered from demolition before the area was preserved. Above are two examples of these kinds of contributing structures.

If ever a case is made against historic preservation, the flaws seem greatest with this form of contextual preservation because these structures are preserved and their modification legally obstructed solely on grounds of their location. Additionally, there are numerous vacant lots within historic districts, where the argument could be made that the legalities of preservation disincentive the kind high-density development that is preferable to developers. However, an analysis of our dataset reveals that non-designated structures comprise less than 15% of all items within historic districts. The data is broken down on the table below, by borough and for the city as a whole:

.

Borough totals 38,881 30,920 28,260 20,887 6,885

.

This yields 128,594 6 protected buildings (designated and non-designated). According to NYC’s public database, there are 857,271 structures total in the city. 7 Meaning that protected buildings comprise slightly less than 14% of all structures in the city. In addition, the non-designated and vacant parcels within historic districts comprise less than 2.16% of the city’s fabric. These values stand in contrast to comparable world cities like Paris and London, which are millennia older and have protected a greater percentage of their historic fabric. Below, for instance, are two comparative maps of the conservation areas (green) in the Westminster area of London 8 versus those in Lower Manhattan and Brooklyn (purple). 9

.

.

Case Study Three: Keeping up to pace?

.

When the first batch of 2,312 historic structures was landmarked in 1965, their average year of construction was 1882 – representing an 83-year gap during which these structures were not protected. In 2018, the average construction year of newly landmarked structures is 1908, representing a 110-year gap. Thus in the 53 year life of the landmarks movement from1965 to 2018, the average age of a building when landmarked has increased by 37 years.

The more recent inclusion of modernist skyscrapers, like the Lever House (1982) and Seagram Building (1989), may give the impression that the criteria for what qualifies as aesthetically important and worth preserving has expanded. Our data does not support this conclusion, because while recent years have seen newer landmarks granted legal status, the rate of designation has not kept up with the rate of construction and, in fact, has fallen behind.

The graph below illustrates the date a structure was registered on the horizontal axis measured against its construction date on the vertical axis. Every single protected structure is plotted on this graph by color. Individual dots represent individual sites. The black trend line indicates the only moderate increase in the numbers of modern structures receiving protection.

.

5,451 records above

.

Is historic preservation falling behind, even though the rate of construction and population has increased? Or, is the city no longer building the kinds of structures deemed worthy of preservation? This 16-year gap could be a fluke, or it could be indicative of larger trends.

To qualify for landmark status in NYC, a building must be older than 30 years or older than 50 if added to the National Register. From a publication by the The Trust for Architectural Easements: “LPC property must be at least 30 years old – no exceptions – whereas a National Register property must be at least 50 years old, unless it is found to be of exceptional significance, in which case there is no age limit at all.”  10 When the LPC was formed in 1965, none of the buildings from 1935 to 1965 would have qualified for designation. Today, as of 2018, any building from before 1988 could qualify. However, less than 5% of all listed structures date from the 43 years from 1945 to 1988 – a significant time in this metropolis’ history as it transitioned from an industrial economy to the world’s financial center and a major hub for tourism.

The graph below illustrates the age range of all landmarks and the distribution of landmarks by year. The horizontal axis corresponds to years, and the vertical axis represents the number of landmarks built in that year that are now included in LPC listings. Clearly, the vast majority falls within the 90-year span of 1850 to 1940, with few landmarks falling outside this range. The peak is in 1895 with 13,275 records from this year alone – a surprising anomaly. The rise and falls on this graph may also correspond to roughly 20-year periods of boom and bust recessions, along with corresponding halts to new construction. The shortage of pre-1850 sites is easily explained by the vagaries of time and the relatively smaller size of the city before 1850. However, the chronic shortage post-1940 may hint at a broader historical oversight or change in the way new buildings are designed and age.

.

93,691 records above

.

The LPC was created partially in response to the demolition of New York Penn Station in 1963. The LPC was an attempt to prevent further destruction of aesthetically significant buildings, many of which had already been lost to progress and urban renewal. By the 1960s, urban renewal was winding down and New York was entering the prolonged recession of the 1970s and 80s, during which the rate of urban renewal and highway construction ground to a halt. In this light, the LPC originated as a post-facto response to demolition that had been going on for decades.

Despite the history of the LPC, must land marking occur after destruction has begun? There are doubtless hundreds of post-war buildings of significance – that have not yet been identified or deemed worthy. The question is not: Should we list these buildings? Rather, the question should be: Why are we not listing these buildings before they are threatened? And why should LPC status be limited to buildings older than 30 years? The demolition of the city’s American Folk Art Museum by MoMA in 2014 is one example. 11 The Temple of Dendur and its custom-built exhibit hall is another instance of an interior landmark completed pre-1988 and potentially eligible for LPC status.

.

Case Study Four:

How might the preservation movement reflect economic patterns?

.

As land values increase, and as it becomes increasingly unsustainable to develop land with single-family residential structures and townhomes, newer buildings are more likely to be commercial, mixed-use, and multi-family. However, the historic preservation movement exhibits a preference toward land-marking residential structures. The table below illustrates the types of buildings preserved, their quantity, and the percentage of the total number of preserved buildings this quantity represents. The buildings are listed below by their original functions. So, a building designed as a factory but more recently converted to residential is still listed as “industrial.”

.

Type of Building Quantity Percent of Total
Residential 35,575 27.66%
Civic 16,920 13.16%
Street Furniture 13,943 10.84%
Commercial 4,574 3.56%
Infrastructure 2,490 1.94%
Transportation 2,145 1.67%
Institutional 2,026 1.58%
Religious 1,509 1.17%
Mixed Use 1,324 1.03%
Vacant 1,178 0.92%
Military 759 0.59%
Industrial 436 0.34%
Outbuildings 12 32,391 25.19%
All other uses 14,970 11.64%
Totals 128,594 100%

.

The most salient figure in the above table is the disproportionate representation of residential and civic buildings that are preserved. For instance, as of 2018, Manhattan has 39,172 landmarked items. Of these landmarks, 35% (= 13,816) are residential use, 9% (= 3,443) are commercial, and 1.5% (= 650) are mixed-use. Mixed use, in this case, is defined by commercial on the lower level and offices or residential on upper floors. However, there are more commercial and mixed-use buildings in Manhattan than there are residential buildings. 13 So, the percentages of landmarked buildings are not representative of the percentage of residential versus commercial and mixed-use buildings that exist. In short, our data supports the conclusion that residential buildings seem more likely to receive landmarked status than commercial structures.

The numbers of landmarked civic structures strengthens the above conclusion. New York City owns 14,000 properties 14 across five boroughs. This MAS estimate does not include public monuments, statues, civic buildings built by the city and later sold, or civic buildings originally built for private use but acquired by the city. Yet, there are 16,920 landmarks designated as serving “civic” functions, including 11,726 landmarked items relating to hospitals and 571 related to armories. In fact, among all the 440 types of landmarks in this city, civic-related structures have the highest rates of landmark status and the rate of preservation closest to 100%.

What explains these inequalities? One explanation could be that civic sites, particularly those built in the early 20th century tend to be high quality, well built, and designed to articulate the civic values of democracy and government through the beauty of the neoclassical style. Therefore, these buildings are more likely to be deemed worthy of preservation. Yet, this interpretation is doubtful because there is little factual basis to assume that civic structures are “better than” commercial and mixed-use.

A more believable explanation could be that civic and residential structures are easier to landmark than commercial. The maintenance and upkeep of civic structures is managed by government and elected officials, who are responsible to voter complaints and community pressure. The public can threaten to vote out of office any leaders who neglect historic, city-owned properties. Additionally, there are few reasons for developers or residents to object to land-marking civic sites, as legally protecting these structures adds more red tape, not to city residents, but to the future bureaucrats who restore these sites. Again, this is speculation.

Still yet, there is a stronger factor influencing preservation. Civic structures are not subject to market pressures, and city-owned buildings do not have to help their occupants make a profit. For instance, the cost of rehabbing a historic public school building might more expensive than just demolishing and rebuilding it new, but the city is under less pressure to demolish the structure because, fortunately, city government is not run like a profit-driven corporation. Historically valuable but functionally outdated city buildings may be more likely to be landmarked and restored than demolished, as illustrated by the unequal distribution of building types in our data.

By contrast, commercial and residential structures are subject to strong market pressures favoring demolition. An old factory that has outlived its designed lifespan and is no long suitable for modern-day production line assembly will be abandoned or demolished if it cannot be converted. Still, the process of conversion may require completely gutting the structure, environmental remediation, and a lengthy approvals process. If the cost of renovation is more expensive than the income the renovated structure can bring in, then there will be greater pressure to demolish than to preserve the fated structure. City-owned libraries and hospitals face less of this kind of pressure.

Our data also reveals a spatial concentration of residential buildings in historic districts. For instance, most of Manhattan’s residential landmarks are concentrated within historic districts in the Upper West, Upper East, and skyscraper valley between Midtown and Downtown. Residential sites are more likely to be collectively landmarked as part of districts. As illustrated in the table below, 94.93% of residential landmarks citywide fall within historic districts, and only 5.07% are outside these districts:

.

Residential All Other Types
Within historic districts 35,029 = 94.93% 61,124 = 66.66%
Individual landmarks outside historic districts 1,872 = 5.07% 30,569 = 33.34%
Total Number 36,901 = 100% 91,693 = 100%

.

What explains the disproportionate protection of residential structures? One possible motivating factor could be income-levels in historic neighborhoods and associated protectionism. The map on the following page overlays the locations of historic districts over 2018 block-level census data for income levels and length of residence. Our analysis reveals a spatial overlap between historic districts and areas with higher incomes and longer-term residents. For instance, the average length of residence for residents in the Brooklyn Heights historic district is between 17.1 and 48 years and incomes range between $51,500 and $289,000, while the rest of Brooklyn averages between 10.3 and 12.8 years and under $51,500 income. Similar patterns play out in the Greenwich Village and the Upper West Side. In short, residents in historic neighborhoods seem more likely to stay-put, and length of residency may be a proxy for measuring the degree to which residents are invested in maintaining the physical appearance and improving their community. From this data, we posit that the relationship between historic preservation and length of residency is too strong and too consistent across the five boroughs to be correlation. There may be causative factors at play between income, emotional investment in one’s community, and preservation, yet this remains to be conclusively confirmed by future data.

Individual landmarks in red outside historic districts in brown tend to be commercial structures.
There is no immediately identifiable relationship between the siting of commercial landmarks,
and the income levels of their adjacent community.

The spatial relationship illustrated above is surprising for another reason: gentrification. Normally, gentrification in the past 20 years is associated with rising income levels and the displacement of existing residents. The physical appearance of historic neighborhoods should also make them more desirable for gentrification. However, the average length of residency is longer in historic than in non-historic districts, even though income (and presumably rent, too) are higher in historic districts. That is, neighborhoods with historic preservation more often have high and rising incomes with long length of residency. This seems contradictory because high-income areas should be more likely to push out longer-term tenants from the pre-gentrification era.

By contrast, neighborhoods without the benefit of historic preservation more often have high incomes and lower length of residency, meaning a high turnover rate. The Williamsburg neighborhood is one example with incomes over $51,500 (similar to Brooklyn Heights) but length of residency under 10.3 years. Additional research should examine if rent-stabilized apartments are more likely to be concentrated in historic districts. There is the possibility that the legal barriers of preservation make it more difficult for developers to push out existing residents, gut an old building, and then rebuild it to charge higher rent. Unfortunately, New York City Open Data has no information on the spread or geographical clustering of rent stabilized apartments.

These possible relationships between historic preservation and gentrification need to be confirmed by further analysis.

Conclusion: The Future of Historic Preservation

.

There are limits to our data – these statistics cannot reveal the intricacy of historic sites, the unique identity of each, or the reasons why each justify (or do not justify) protection. This data can, still, reveal big picture trends in preservation, its biases, and some of its problems. While these trends are not visible from walking the street or looking at individual sites, they become visible through the lens of data. This data may also reveal causative relationships between income, length of residency, and the political strength of preservationists.

From this data-driven analysis, we can make deduct several conclusions:

  1. Historic preservationists prefer to landmark and protect pre-WWII buildings, even though numerous post-war examples may qualify. As a result, there are a disproportionately high number of pre-war buildings with landmark status, and comparably few post-war landmarks – less than 5%. Similarly, the rate at which landmarks are designated has not kept up with the pace of new construction.
  2. The market pressures to demolish civic structures are weaker than the market pressures to demolish commercial and residential. As a result, a disproportionately high percentage of city-owned or institutional buildings are preserved, and a disproportionately low percentage of commercial and industrial.
  3. Tangent to the previous point, a disproportionately high percentage of landmarks are for residential use and fall within residential districts. This may indicate that landmarks preservation is a strategy for neighborhood protectionism – that is, an effort by residents to ensure that the appearance of their community is not changed due to new development. Neighborhoods of lower-density old buildings, like the West Village, retain their popularity, charm, and high property values thanks to strong legal barriers against change that could lead property values to depreciate. While these barriers may discourage and prevent developers from reaping larger profits by building higher and larger, they also ensure that existing residents’ investment in their condos or homes will remain more stable.
  4. The, economic success of New York on a global scale and its continuing construction boom has led to the demolition of many non-residential commercial landmarks that might have otherwise qualified for landmark status had New York not been as successful. In the words of Professor Kenneth Jackson: 15

History is for losers. By that I mean, cities which have chosen to preserve all their historical monuments and locations usually do so because no one else wants the land to develop. Modern progress has passed them by. New York’s history doesn’t litter the streets visually, it can be hard to find sometimes, but that is because the city is an economic winner on a global scale.

.

New York is indeed a winner “on a global scale,” with Wall Street as a symbol of America’s economic power, the United Nations as a symbol of political power, and the city’s over three million foreign born as representative of power of immigration and globalization to shape a city. Nonetheless, this progress comes at a historic and aesthetic cost – the consequences of which are reflected in the dark and sterile skyscraper canyons of Midtown, the worsening congestion in cars and subways, and (more pressingly) this city’s fragility when faced with ecological pressures, such as flooding, hurricanes, and climate change. At the level of historic preservation, this progress comes at the cost of losing New York’s distinctive architectural heritage to the force of globalized change. The Gilded Age mansions on Fifth Avenue and the built-to-last-forever Penn Station are gone, as are the picturesque skylines and distinctive ethnic neighborhoods of Berenice Abbott’s 1930s photographs. The New York of today is different – whether it is architecturally poorer for progress can only be judged in retrospect. Historians prefer not to speak of what-ifs when writing about history, but would it have been possible to accept the benefits of progress without sacrificing history? This, however, is a question beyond the limits of data to contemplate.

New York: City of Immigrants

The Viaduct

Golden Rectangles SuperimposedAs northbound Broadway dips down to the valley of 125th Street, the subway soars above. A jumble of steel slicing through the orthogonal city grid. A massive arch, 250 feet from end to end. Two hundred tons of mass channeled into four concrete pylons, resting on the solid bedrock of Mannahatta.[1] It is the intersection where the underground and aboveground worlds of New York converge.

The subway, the alphabet lines that snake their way beneath the city and above the boulevards. Take the  to Brighton Beach, the to Jamaica, the to Forest Hills. From the towers of Midtown, to the factories of Flatbush, to the shouts of Shea Stadium, the subway is a panoply of color, motion, and people. For the price of $2.75, the world is within reach. Chinatown, Little Poland, Russia, Greece, India, and Italy, all neighborhoods joined by the umbilical cord of the subway. New York is a world unto herself, knit together by the bands of black asphalt and steel subway track.

Voice of the City - Joseph Stella, 1922

Voice of the City by Joseph Stella, 1922.

Once wooded island of the Lenape Indians, now home to a peculiar race of people. Every day, New Yorkers step to the tune of the stoplight. Every day, they ride in sardine can subways. Like smoked ham on the butcher’s hook, they hang from subway straps. At their respective stops, they scramble on to work, home, and family. All New York is a stage, and all the men and women merely players. They have their entrances as subway doors slide open, and they time their exits to the familiar recording of “Stand Clear of the Closing Doors Please.” [2]

 

New York, New York, home of the Lenape, town of the knickerbockers, and city of immigrants and refugees. The Irish fleeing famine in 1845, the Germans fleeing Revolution in ‘48, the Italians in ’71, and now waves of Dominicans and Mexicans, Chinese and Czechs. As the metropolis pulsates in motion, the spirit of the city evolves with each wave of newcomers who ride her subways, inhabit her humid tenements, and dream of home, family, and future.

In 1856, Walt Whitman published “Crossing Brooklyn Ferry.”[3] He writes of immigrants and bourgeois businessmen alike, all part of “the simple, compact, well-join’d scheme, myself disintegrated, every one disintegrated yet part of the scheme.” The scheme of the city. The cogs of capitalism. The human machinery of the metropolis. To each immigrant her place, to each worker his seat, and to each vagabond a place in the breadline. Together they form the metropolis.

 

Whitman also writes:

Others will enter the gates of the ferry and cross from shore to shore,

Others will watch the run of the flood-tide,

Others will see the shipping of Manhattan north and west, and the heights of Brooklyn to the south and east,

Others will see the islands large and small;

Fifty years hence, others will see them as they cross, the sun half an hour high,

A hundred years hence, or ever so many hundred years hence, others will see them,

Will enjoy the sunset, the pouring-in of the flood-tide, the falling-back to the sea of the ebb-tide.

 

Rome is nicknamed the “Eternal City” for its ancient architecture and generations of development. New York, too, is an “Eternal City” of sorts. Its skyscrapers may rise and fall with changing tastes and a growing economy. In the face of all change to the built environment, people remain the “eternal” constant that marks life in this city: a city with over three million foreign born from all corners of the world; a city whose functioning depends on the legions of immigrant window washers, janitors, and taxi drivers without whom this urban machine would screech to a halt. In 1856, Whitman wrote of a fluid and dynamic city of people not unlike the New York of today.

New York, you have not the tree-lined boulevards of Paris, the pomp of London, the antiquity of Rome, the parks of Peking, or the beauty of Budapest. But in your diversity of people, cuisine, and culture, you are something far greater. You are home to a city of strangers, a city of neighborhoods, a city of sound. A city of subways, taxis, and buses flowing from the canyons of Midtown to the quiet bedrooms of Westchester and Park Slope, like rivulets of water. Flow on city, flow with the tide, and glide through the eras. Flow on Isle of Mannahatta for “a hundred years hence.” A ship anchored on bedrock between the two proud rivers of the Hudson and East.

 

 

But, New York, you too are home to the injustices and inequalities urban life nurtures. Hart Island, New York’s pauper’s cemetery, is the final resting place of over a million mostly unknown corpses, the tired, the poor, and the huddled masses of immigrant New York. Over a quarter million infants are buried here, each one in an unmarked coffin hewn of pine, the size of a shoebox. Mass graves three coffins deep and 25 long. Nearby Riker’s Island, America’s largest jail, imprisons 10,000 a night awaiting trial in the city’s many courthouses. The South Bronx, per capita income $12,500, is a mere mile away from the Upper East Side, per capita income $85,000+. The glassy condos of Manhattan are priced at a million plus per piece, but these homes are only made possible by the immigrant workers and janitors paid $10 an hour to sweep the hallways of dust and wipe the windows of grit. Every night, these laborers, too, return to their homes in the gritty outer boroughs. They, too, ride the subway that burrows underground, as generations have before them.

In the 1880s, social reformer Jacob Riis was working on How the Other Half Lives. [4] Through photography, he captured the squalor, darkness, and misery of New York’s impoverished immigrant community. He showed children at work in sweatshops, vagabonds at work collecting the refuse of those more fortunate. He exposed the darkness of another world a few steps from Wall Street and a few miles from the opulent mansions and department stores of Fifth Avenue and Ladies’ Mile. That very same year, on March 26th 1883, the Vanderbilt Family of railroad fortune hosted the largest and most expensive costume ball in New York history, costing six million in today’s currency. While the idle rich came dressed as the “Count of Monte Cristo” and “Otho the Barbarian,” the poor slept in squalor a carriage ride away in the Lower East Side. As the New York Sun reported three days later, “[This] festivity represents nothing but the accumulation of immense masses of money by the few out of the labor of the many.” [5]

 

 

Though a century has passed since Riis, New York still is a city of social contrasts and economic disparity. Ironically, Jacob Riis’ Lower East Side is now a fashionable community for the upper middle class. All the same, the eternal New York City of immigrants endures in the outer boroughs of Flushing, Queens, Jackson Heights, South Bronx, and Bed Stuy. In many regards, their social condition is not too different from Riis’ era. His images of New York testify both to how much and to how little New York has changed. America’s Eternal City still is a place of great inequity and injustice.

New York aggregates and accents both the dynamism and the dangers of urban life. New York, a place of wealth and of anonymity. New York, a place for the powerful and for the disempowered. To appreciate the beauty of this environment, one must realize that this city, too, like Chicago, Paris, and London “has been [and still is] one of the dark places of the earth.” [6] New York, like any living individual, has both beauty and darkness. This product of human labor and ingenuity is only as perfect as its imperfect Creator.

George Tooker depicts the alienation of urban life in his 1950 painting "Subway."

Subway by George Tooker, 1950.

As E.B. White wrote in 1949: “The city is like poetry: it compresses all life, all races and breeds, into a small island and adds music and the accompaniment of internal engines. The island of Manhattan is without any doubt the greatest human concentrate on earth, the poem whose magic is comprehensible to millions of permanent residents but whose full meaning will always remain illusive.” [7] Over 400 years since New York’s founding in 1609 by the Dutch, these words remain true as each generation of Men and Women creates the City in their own image. [8]

Love and Longing in New York

 

Walking is my form of enlightenment.

I live in Newark.  My city is generally ten degrees hotter than its neighboring environment.  The airport.  The port.  The downtown.  All are blanketed in asphalt that turns my city into a hot desert.

Tens of thousands of cars, and one of the largest garbage incinerators in the country, spew their fumes into my city.  Returning home, the smell of burning garbage often greets me.  As a child, I had asthma.

At night, I am alone.  Nobody my age lives in my neighborhood. From my front window, I see a parking lot for corporate commuters. From my back window, I see a vast parking lot for university students.  Both are desolate after dusk. As an infant, my first words were “demolition” and “truck.”  As a child, I never had play dates; my suburban “friends” feared my city.  As an adult, I hope to see my city’s vacant lots developed.  I keep on dreaming.

The streets of my city are not made for walking.  They are made for driving.  I walk.  I stop.  I wait.  Speeding traffic and interminable stoplights hinder my progress.

But I love walking in New York City.

When I walk, I am free to choose.  Each street guides me forward.  Each intersection is a choice.  Each destination is irrelevant.  When I walk, I sometimes choose a random order of directions, left, right, left, right, right, left, left, straight.  I see where they lead me.  I know not where.

When I walk, I am free to move.  I love walking on the High Line.  I float above the cars that prevent the city from realizing itself as a community.  I see the crowded streets twenty feet below.  I see the gardens on either side of me.  I let the verdantly landscaped path channel me forward.

When I walk, I am no longer alone.  I walk in the footsteps of the millions who passed before me.  I am one among millions, all of us on our separate voyages.  Lawyers.  Butchers.  Tourists.  Homeless.  We all walk alone.  Yet, we are together in walking alone.

When I walk, I see the world.  In Spanish Harlem, street fairs sell traditional Mexican foods.  In college town Columbia, well-dressed university students amble on their way to class.  In the Upper West Side, the shabby chic push their grocery prams.  In Times Square, tourists lug their large shopping bags from theater to theater, store to store.  Finally, after many neighborhoods, I reach the ceaseless bustle of Wall Street.  Tired after many miles of walking, I descend the subway steps.

When I walk, I achieve tranquility. I am happy.

One of my recent projects is painting New York City, neighborhood by neighborhood.  Each day, I choose a new district to stroll through.  Then, equipped with my miniature watercolor palette and notepad, I walk and paint.  I discover the city block by block.  I aim to capture a fragment of what I see through painting.

Like a pianist who memorizes music by heart, the flâneur (or urban pedestrian) embraces the street symphony with his soul and feet.  People’s voices and buildings serve different, but equally important, clefs in the symphony.  As le Corbusier wrote, “… first to look, and then to observe, and finally to discover.”  My countless urban walks enhance my passion for cities, their architecture, their history, and their planning.

Living in Newark inspires me to dream.  Walking in New York City enlightens me to walk.  I am ready to walk my next journey.
