Madrid’s mayor is determined to clean up its air – by pedestrianising its biggest shopping street

This month, a fairly innocuous A-road in south London breached a 2017 pollution limit just five days into the year. On the same day, Madrid’s left-wing mayor pledged to ban cars from a massive six-lane highway through the heart of the Spanish capital. If Manuela Carmena gets her way, Gran Vía, one of Madrid’s busiest roads but also a major shopping hub like Oxford Street, will be almost completely pedestrianised by 2019.

Her plans are part of a bold green vision that includes banning cars from the city centre, and even stretches to installing gardens on top of buses and bus shelters. They also represent the latest skirmish between the city and the private vehicle in the battle to make major metropolises somewhere it’s actually safe to live.

The proposals, which were tested out over the Christmas period, transform nearly half the road into pedestrianised zones, allowing shoppers to spill safely off narrow pavements while the rest of the street is left to public transport and the odd resident’s car. Importantly, other major roads in the area also face stringent traffic limits, making it devilishly difficult to dodge the restrictions with rat-runs through the centre. Officials are now analysing the temporary experiment ahead of implementing a permanent ban – but Carmena has confirmed she has every intention of carrying it out before her term ends in 2019.

Carmena, who leads the Ahora Madrid coalition backed by left-wing populists Podemos, appears to be moved by aesthetic as well as environmental concerns. Outlining her plans in a 4 January interview with Spanish radio station Cadena SER, she described the model for Gran Vía’s car ban – the street of the same name in Bilbao 0 as “deliciously pedestrianised”. Other city officials have also been quoted saying the broad aim is to make the place “well, just nicer”.

But the green case is uncontroversial and urgent. Campaigners estimate traffic fumes in Madrid kill as many as 2,000 people each year – something attributable to a toxic cocktail of over-reliance on the car and a natural atmospheric phenomenon that traps pollution in the city. Madrid has one car for every two of its 3.2m inhabitants, and its position on a plateau means that, in winter months, smog often grips the city literally in a choke-hold. Locals call it La Boina, or “The Beret”, because of the way the fumes sit like a hat above the city centre.

Environmental activist Simon Birkett, who runs the Clean Air in London campaign group, believes Madrid’s efforts demonstrate a “wonderful competition”, driving attempts from city mayors across Europe to out-do each other. The Spanish capital’s measures, he says, send a message to London to “get on with pedestrianising Oxford Street”.

However, he urges caution over implementation. “It’s similar in a way to the Oxford Street issue,” he says. “The risk is that you shut off that road and you get people driving around the side streets. What I would say is you have to combine this with the halving of traffic in the whole area.”

His warning is not wide of the mark. When Gran Vía’s temporary car ban was put in place over Christmas, it initially led to bottlenecks at key junctions while motorists came to terms with the restrictions.


But Madrid is also behind a greater assault on the private vehicle. On 29 December, half of all cars were banned from the centre on the (fairly arbitrary) basis of their number plates. It was an unprecedented response to spiking NO2 levels, and seemed like a radical statement of intent in the battle to make the city more liveable.

Other policies take a more softly, softly approach – such as the polite messages on the Metro that thank passengers for choosing public transport on particularly polluted days. What’s more, city transport bosses are trying to get their own house in order by completely replacing dirty, inefficient diesel buses with a 2,000-strong fleet of greener electric vehicles by 2025. In the meantime, officials want to plant gardens on top of buses and bus stops in an effort to soak up CO2 emissions, with shrubs being dug into turf aboard the vehicles at a cost of €2,500 a pop.

When Gran Vía was built at the beginning of the 20th century, it was considered an axe blow through the heart of Madrid. The bold project to effectively construct a Spanish Broadway – part arterial traffic link, part entertainment hub lined with theatres, restaurants and bars – led to disruption and meant the demolition of dozens of buildings.

Some one hundred years on, the theatres have been replaced by shops, and the street is again the focal point of an inevitably disruptive plan. But now, as then, the bold steps are necessary if Madrid wants to remain a modern and bustling yet liveable city. The current administration, it seems, is willing to drive the change. 

 
 
 
 

Urgently needed: Timely, more detailed standardized data on US evictions

Last week the Eviction Lab, a team of eviction and housing policy researchers at Princeton University, released a new dashboard that provides timely, city-level US eviction data for use in monitoring eviction spikes and other trends as Covid restrictions ease. 

In 2018, Eviction Lab released the first national database of evictions in the US. The nationwide data are granular, going down to the level of a few city blocks in some places, but lagged by several years, so their use is more geared toward understanding the scope of the problem across the US, rather than making timely decisions to help city residents now. 

Eviction Lab’s new Eviction Tracking System, however, provides weekly updates on evictions by city and compares them to baseline data from past years. The researchers hope that the timeliness of this new data will allow for quicker action in the event that the US begins to see a wave of evictions once Covid eviction moratoriums are phased out.

But, due to a lack of standardization in eviction filings across the US, the Eviction Tracking System is currently available for only 11 cities, leaving many more places facing a high risk of eviction spikes out of the loop.

Each city included in the Eviction Tracking System shows rolling weekly and monthly eviction filing counts. A percent change is calculated by comparing current eviction filings to baseline eviction filings for a quick look at whether a city might be experiencing an uptick.

The tracking system also provides a more detailed report on each city’s Covid eviction moratorium efforts and more granular geographic and demographic information on the city’s evictions.

As part of their Covid Resource, the Eviction Lab together with Columbia Law School professor Emily Benfer also compiled a scorecard for each US state that ranks Covid-related tenant protection measures. A total of 15 of the 50 US states plus Washington DC received a score of zero because those states provided little if any protections.

CityMetric talked with Peter Hepburn, an assistant professor at Rutgers who just finished a two-year postdoc at the Eviction Lab, and Jeff Reichman, principal at the data science research firm January Advisors, about the struggles involved in collecting and analysing eviction data across the US.

Perhaps the most notable hurdle both researchers addressed is that there’s no standardized reporting of evictions across jurisdictions. Most evictions are reported to county-level governments, however what “reporting” means differs among and even within each county. 

In Texas, evictions go through the Justice of the Peace Courts. In Virginia they’re processed by General District Courts. Judges in Milwaukee are sealing more eviction case documents that come through their courtroom. In Austin, Pittsburgh and Richmond, eviction addresses aren’t available online but ZIP codes are. In Denver you have to pay about $7 to access a single eviction filing. In Alabama*, it’s $10 per eviction filing. 

Once the filings are acquired, the next barrier is normalizing them. While some jurisdictions share reporting systems, many have different fields and formats. Some are digital, but many are images of text or handwritten documents that require optical character recognition programs and natural language processors in order to translate them into data. That, or the filings would have to be processed by hand. 

“There's not enough interns in the world to do that work,” says Hepburn.


Aggregating data from all of these sources and normalizing them requires knowledge of the nuances in each jurisdiction. “It would be nice if, for every region, we were looking for the exact same things,” says Reichman. “Instead, depending on the vendor that they use, and depending on how the data is made available, it's a puzzle for each one.”

In December of 2019, US Senators Michael Bennet of Colorado and Rob Portman of Ohio introduced a bill that would set up state and local grants aimed at reducing low-income evictions. Included in the bill is a measure to enhance data collection. Hepburn is hopeful that the bill could one day mean an easier job for those trying to analyse eviction data.

That said, Hepburn and Reichman caution against the public release of granular eviction data. 

“In a lot of cases, what this gets used for is for tenant screening services,” says Hepburn. “There are companies that go and collect these data and make them available to landlords to try to check and see if their potential tenants have been previously evicted, or even just filed against for eviction, without any sort of judgement.”

According to research by Eviction Lab principal Matthew Desmond and Tracey Shollenberger, who is now vice president of science at Harvard’s Center for Policing Equity, residents who have been evicted or even just filed against for eviction often have a much harder time finding equal-quality housing in the future. That coupled with evidence that evictions affect minority populations at disproportionate rates can lead to widening racial and economic gaps in neighborhoods.

While opening up raw data on evictions to the public would not be the best option, making timely, granular data available to researchers and government officials can improve the system’s ability to respond to potential eviction crises.

Data on current and historical evictions can help city officials spot trends in who is getting evicted and who is doing the evicting. It can help inform new housing policy and reform old housing policies that may put more vulnerable citizens at undue risk.

Hepburn says that the Eviction Lab is currently working, in part with the ACLU, on research that shows the extent to which Black renters are disproportionately affected by the eviction crisis.

More broadly, says Hepburn, better data can help provide some oversight for a system which is largely unregulated.

“It's the Wild West, right? There's no right to representation. Defendants have no right to counsel. They're on their own here,” says Hepburn. “I mean, this is people losing their homes, and they're being processed in bulk very quickly by the system that has very little oversight, and that we know very little about.”

A 2018 report by the Philadelphia Mayor’s Taskforce on Eviction Prevention and Response found that of Philadelphia’s 22,500 eviction cases in 2016, tenants had legal representation in only 9% of them.

Included in Hepburn’s eviction data wishlist is an additional ask, something that is rarely included in any of the filings that the Eviction Lab and January Advisors have been poring over for years. He wants to know the relationship between money owed and monthly rent.

“At the individual level, if you were found to owe $1,500, was that on an apartment that's $1,500 a month? Or was it an apartment that's $500 a month? Because that makes a big difference in the story you're telling about the nature of the crisis, right? If you're letting somebody get three months behind that's different than evicting them immediately once they fall behind,” Hepburn says.

Now that the Eviction Tracking System has been out for a week, Hepburn says one of the next steps is to start reaching out to state and local governments to see if they can garner interest in the project. While he’s not ready to name any names just yet, he says that they’re already involved in talks with some interested parties.

*Correction: This story initially misidentified a jurisdiction that charges $10 to access an eviction filing. It is the state of Alabama, not the city of Atlanta. Also, at the time of publication, Peter Hepburn was an assistant professor at Rutgers, not an associate professor.
