Interviewer: And what makes Casa de Oro different? What distinguishes it?

Informant: Well the name of course.

 

I. In October 2020 I tried to walk around the edge of the Tijuana-San Diego metropolitan area. I say tried because on the ninth day of the walk around Tijuana I was interrupted by men with arms and radios inducing me to flee the city. Later in San Diego, injuries forced me to twice take public transport for small stretches along the coast. Aside from these imperfections, I walked continuously as well as I could where city meets countryside, advancing between 20 and 30 kilometers a day, staying in hotels on the periphery, taking photos, falling into conversations, eating whatever was at hand and taking in the urban landscape.

But before discussing this experience I would like to clarify what I mean by the edge of a city and why I find it interesting

                        Sorry for trespassing: A layman’s defense of walking urban edges

For my purposes the edge of a city is the shortest route passing through at least 100 meters of open country around a given city. If there is building more than 100 meters out it is, as far as this definition is concerned, outside the city. Open fields enveloped by the city are, according to this definition, inside the city. Though this definition is arbitrary it is roughly applicable to the definition of urban agglomeration used by the UN, namely a kind of contiguous settlement.

In the field 100 meters is a distance, which is easy for most people to estimate and walk. It also allows for the spatial comparison of urban infrastructures, such as highways entering the city, according to a fixed measure. As an algorithm this definition generates a spatially precise edge for any settlement. Applying this criterion, I have at the time of writing walked around the Greater Mexico City Area, Kigali in Rwanda, Tijuana, and San Diego.

The edges of cities are like their fingerprints. When you walk along the edge of a city you are constantly running into the city’s strategic infrastructure. High-tension lines, highways, nurseries for plants, garbage dumps, recycling plants, prisons, military bases, airports, junkyards, cemeteries, universities, suburbs, and gated communities are all phenomena which I associate with the edge of cities and which repeat themselves over the landscapes of different cities, almost forming a vocabulary.

Just like the pyramids tell us about their builders, we can examine the material culture of the edges of our growing cities to better understand what drives us. In the end this project is a kind of archeology of the anthropocene, observing that space where we are materially expanding and trying to understand the builders.

II. The Tijuana-San Diego Borderplex is a rare example of an urban agglomeration split between Global North and Global South.

According to the UN, San Diego had a population of 3.2 million in 2018 and will grow to 3.5 million by 2030. Meanwhile, Tijuana had a population of 2.2. million in 2018 and is expected to grow to 2.5 million in 2030. The two cities are connected at the border crossings of San Ysidro in the west and Otay Mesa in the east, from where a spidery web of residential neighborhoods and factories connect to Chula Vista, Eastlake, and greater San Diego.

According to US government data, 70,000 cars and 20,000 pedestrians cross from Tijuana every day at the world’s fourth largest border crossing in San Ysidro. Many of the maquilas in Tijuana export their finished products directly north. Many have administrative and operational offices in San Diego and in fact San Diego itself has very little manufacturing capacity, as if its manufacturing has been outsourced to Tijuana. Tijuana is isolated from the Mexican energy grid and connects to San Diego. The money, arms, and even the ideology fueling Tijuana’s bloodshed come from the north.

Significantly, Tijuana lies very far from other large Mexican cities in a remote corner of the urban system.  People in Tijuana measure relative to San Diego, whereas in many other parts of Mexico being successful implies being successful relative to Mexico City. I imagine most people in Tijuana would feel more culturally comfortable in San Diego than in most of Mexico.  

Instead of two different cities I tried to imagine Tijuana as a district in a larger urban constellation, as if it were a strange peripheral neighborhood of one big city. In that sense I hoped that perhaps the asymmetries between Global North and Global South would be visible as metropolitan problems. I decided to try to forget about the United States and Mexico and to think about the Tijuana District of San Diego Center.

In Tijuana District, daily water consumption per capita is 204 liters per day[1]. In San Diego Center it is 492 liters per day[2], despite the fact that they share the same hydrological basin. Credit is much easier to get in San Diego Center and the average citizen has a debt of $75,000 USD[3], 77% of which is to pay for mortgages on houses.  In Tijuana District less than 5% of all credit is for mortgages and the average citizen has a debt of $1,300 USD[4] of mostly consumer debt.

In Tijuana District the average income per household was approximately $3,000 USD per year in 2018[5] while in San Diego it was $68,000 USD[6] per year. Understandably, movement between Tijuana District and San Diego Center is restricted and only 3%[7] of the district’s population is allowed to cross to San Diego Center.

It is much easier for people to get to Tijuana District than to San Diego Center. Thousands of migrants are constantly seeking housing in Tijuana District in the hope of getting to San Diego Center. The district administration takes care of this growth by letting people build dwellings themselves and grudgingly bringing in services – or leaving the whole problem to developers.  

The district administration is historically notorious for corruption. The police are badly paid, badly trained, and easily infiltrated.  Alcohol was legal during the prohibition era and the district has been influenced by organized criminals from San Diego. Just as it is easier to bring people to Tijuana District than to San Diego Center, it is also easier to bring illegal substances there. These illegal substances are then transported to San Diego Center where they are redirected and sold on the black market. As San Diego Center cannot seem to stop the crossing of these illegal substances in its own territory, part of the money from this illegal trade accumulates in Tijuana District.

Competition in this lucrative illegal business is fierce, the stakes are high, and the market is fragmented. The actors are criminals. The chances of being caught for murder are much lower in Tijuana District. And so a wave of mutual killing breaks out. Because the different actors fear for their lives, they create strongholds within Tijuana District where it is difficult to approach them. They arm, organize and evolve.

While San Diego Center has the largest concentration of military assets on earth[8], its Tijuana district was the second most violent city in the world in 2020[9].

III. The edge of Tijuana sprawls over arid, eroded landscapes, full of ravines and steep hills. Car tires are everywhere, holding up fragile slopes bare of vegetation. The sun beats down on crumbling, pale earth, pretending to be rock but falling apart when you grab it.  Tenuous streams of untreated water can be found at the bottom of little ravines where abruptly an almost tropical vegetation of banana and palm trees sprouts up surrounded by jerry-rigged houses of wood and concrete. The country edge is mostly rock and dirt, with the occasional cottontail hare bounding over through the low brush, a vulture soaring above. The sky is intensely blue and the light is startlingly clear.   

Compared to the edge of the Greater Mexico City Area, the edge of Tijuana is uncomfortable to walk. There is less commerce, fewer hotels, and places to eat are harder to find. The landscape is harsh, hot, and dry and the scenery is vivid and post-apocalyptic.

Aside from a flat stretch eastwards along the border from the airport to the Otay Mesa full of lots for trailers and boxy maquilas and the small beachfront area, the edge of Tijuana is all hilly. Particularly to the southwest, Tijuana is dispersed over ridges and valleys where flat land is hard to find. In some ways the urban structure in that part, with its many social housing units, resembles San Diego, with parkway like avenues lined by sloping embankments connecting fragmented housing projects.

But a lot of the walking is also in the countryside, beyond the freeways ringing the city. There are slopes on the hills in and around Tijuana, which seem completely devoid of life, all rocks and gravel.

Tijuana’s edge is mostly composed of either self-built housing in various stages of consolidation, social housing units with tiny accommodations in various stages of decay, or maquilas and their logistical support. Compared to the edge of Mexico City, housing is shoddy. The social housing units are smaller and seem to be falling apart even faster. The self-built housing teeters more ominously and seems more crooked. The dogs are more ferocious.

The dynamic of self-produced housing in Tijuana marks an important difference with San Diego. Many Mexicans cannot access a mortgage and therefore cannot buy a ready-built house. So instead of paying interest they pay to build up a house on land they have somehow acquired. This process can typically take from 10 to 30 years, but then many Mexicans do have a house, which might be in some ways a better value than houses bought with a mortgage when they are finally paid off and starting to fall apart.

The self-built housing in Tijuana uses more wood and plywood than in central Mexico. This seems to be inspired by the houses of San Diego, which are often made of sheets of plywood over wooden frames covered with stucco.

Social housing seems to function as a reservoir for formal workers who can pay mortgages by receiving maquila salaries. Houses are often tiny and many are visibly decaying. Buses bringing the workers back and forth to the clean generic maquila factories in their grey boxes complete the circuit through the ragged city.

In any case many Tijuanenses hope the border will be a temporary stop on the road to San Diego, and do not seem to want to get overly invested in real estate.

IV. Walking the edge of San Diego is like shuffling behind the scenes on a film set. The scenery floats by but cannot be touched. Then you realize it was all made to be seen from cars or, at best, from homes. From the parkways the suburbs are an oasis. But there are no benches, bathrooms, shops, or fountains. In fact there are few parks in the suburbs. Barely anybody is on foot. Pedestrians are either exercising, walking their dog, or, usually, homeless.  I was clearly not exercising or walking my dog and during those 12 days most people assumed I was one of the multitudes of homeless or unhoused people shuffling around the city’s streets.

To be without wheels in San Diego is to have hit rock bottom. The homeless San Diegan first loses his house, but it is the loss of the car that spells true disaster. After that you are reduced to a bicycle, a skateboard, a shopping cart and then perhaps finally a wheel chair.

I learned that San Diego is the skate board capital of the world.  To have no wheels is to have your wings plucked off. Significantly, local low-rider culture holds up beautifully remodeled cars for almost mystical veneration, perhaps in the end the greatest art the region produces.  

The edge of San Diego is hard to find and practically impossible to walk, yet in some ways it is more extreme than Tijuana’s. Steep hills reach out over a narrow coastal plain down to the ocean. Trees shoot up like flowers. In San Diego, the edge of the city can roughly be sub-divided into the coast, the residential suburbs sprawling over hills to the North, South and East interspersed with older towns such as El Cajon, Poway, and Santee, and an industrial corridor between the San Ysidro and Otay Mesa border crossings.

An uncanny visual culture permeates the city. On the beach an almost theatrical mania for appearance is present, not so much for sexual attractiveness but rather as a form of expression of identity, the proof of discipline and hard work etched on one’s muscles. Inland in the suburbs, all the houses are some shade of beige. People move to the heights for the views. Ridges seem to the taste of luxury developers, who line both sides with houses with views looking down on the ocean, unspoiled nature, and a gardenlike city where buildings blend in with the landscape.

Getting from inside the city to outside the city means jumping over fences and then picking one’s way through the brush, like an animal. 

With a talent for appearance also comes a knack for disappearance. One day an unmarked white van pulled up across the road as I was walking. A uniformed border patrol agent stepped out, walking toward me with the characteristic hands-on-hips, pigeon-toed, gunslinger walk of United States police officers. A concerned citizen had called and I was on foot and suspicious. It was all sorted out quickly with a business card and a passport. But if it hadn’t been, I would have ended up in the far-away south east corner of San Diego in Otay Mesa, where eight judicial facilities lie hidden in a dusty quadrant of the desert just beyond the city’s edge.  

San Diego speaks the language of invisibility.

V. Being on foot means you see many things that are not on maps. Among the most interesting to me is public art.

On this walk, the edge of Tijuana presented itself as a morality play: the mother separated from her children, the criminal become a preacher, the successful migrant deported and homeless, the student become an assassin. In this sense Tijuana is quite transparent and its public art reflects an awareness of such moral voyages. What you see is what you get.

Tijuana’s arts scene is justly acclaimed. Artistically the Tijuana side of the border wall is spectacular, a raucous collage of murals and interventions, practically all done on the artists’ own initiative amid the disorder of the city. Many of the works seem rebellious, expressing one way or another, moral indignation or defiance. 

Fittingly in Tijuana the representation of the Virgin of Guadalupe is a regular motif, a role reserved for the flag of the United States in San Diego.

The Stars and Stripes is everywhere north of the border: on towels, bathing trunks, trucks, car washes, random walls, and even painted on rocks. In fact, many advertisements and shop fronts are red, white, and blue. In general, public art in San Diego seems to be about making people feel good about themselves, where they are, and what they are a part of. Naturalistic bronze statues with idealized animals, people, and situations abound.

In San Diego, public art on the edge of the city can be divided into two geographies, that of the coast and inland.

The beach culture in, for example, Pacific and Mission beaches is spectacular and I found much of the public art there to be colorful and somehow quizzical or whimsical. Often the imagery is related to surfing. The works themselves are decorative but well executed and don’t generally raise social issues, nature, and the ocean being common themes.

The public art changes inland. Here the public art (if there is any at all) is related to a romantic interpretation of local history or it is purely decorative. Murals are often childishly executed, unambitious, and cartoon-like.  Notably, this art in some parts is used to cover things which might be considered ugly such as fuse boxes. Rather than art, or even attempt at art, they are camouflage.

Whereas Tijuana’s public art expresses its psyche, San Diego’s seems to hide it. Grief, pride, and anger are easily seen in public art in Tijuana. Looking at public artwork in Tijuana very clearly reveals what is going on there. But public art in San Diego tells one very little about the issues at play in the city. The general message it sends is that everything was, is, and will be fine. And who would doubt it while coasting along parkways lined with trees and flowers, in the best commute the United States has to offer?[10]

San Diego is more discrete than Tijuana. Only in hidden spaces, under bridges and along culverts, a powerful and dark San Diegan expressionism, reveal themselves in often striking graffitis.

VI. The physical differences between the edge of San Diego and the edge of Tijuana seem to hinge on water and credit.

San Diego received $33 billion USD in military spending in 2020[11], which in the end is financed by the United States budget deficit. Meanwhile, residential development is financed by mortgages. This is not to say that San Diego’s lively economy will not make good its return on investment, just that in San Diego things are built or done in advance and paid for later through the intermediation of the financial sector. Tijuana does not have such credit facilities and everything must be paid for on the spot, which is why it looks as if it is being built up incrementally over time as money becomes available.

San Diego’s landscaping uses a great deal of water. Enormous green lawns stretch out over the few public parks. Trees reach to the sky. The sputtering rhythm of sprinklers is common sound, signs amid the plants stating that the water is not potable, probably more a reminder for the homeless to stay away than an apology for excess water use.

The edge of Tijuana runs largely over eroded desert. The city’s surroundings are an ecological disaster area and the landscape is incredibly barren. Thirst is an issue in Tijuana and I have met people who simply didn’t have water.

San Diego has its own vulnerabilities. The sprinkler systems and lavish landscaping that push up land values in the semi-arid desert of San Diego do not seem to be resilient in the face of severe drought, should that come. Rain, finance, and government spending can be fickle things.

San Diego is already facing a major homelessness crisis. The number of homeless people on the city’s streets itself shows a lack of resilience in the urban fabric, an incapacity to naturally reabsorb marginalized individuals.

As long as the status quo is robust, San Diego will do fine. But as I walked the streets of San Diego I would occasionally see a look of almost panicked terror in people’s eyes as I approached. Many people in San Diego are frightened, even if at first sight they do not have much reason to be so. Maybe they see something we cannot.
