99% Invisible - 545- Shade Redux

Episode Date: July 18, 2023

This past May, the city of Los Angeles rolled out a brand new, state-of-the art feature for bus shelters. It’s called La Sombrita. La Sombrita is a metal screen that’s intended to provide shade for the thousands of people who ride the bus every day. The shade screen is about two feet wide, ten feet tall, and it kinda looks like a curved teal metal surfboard filled with tiny holes. Right away, Angelinos were not happy. This heated conversation got us thinking about our interview with Sam Bloch about inequality and shade and we asked Sam back to get thoughts about La Sombrita, and whether the controversial shade sail could actually be a good thing for shade-starved Angelinos. Shade Redux

This is 99% invisible. I'm Roman Mars. This past May, the city of Los Angeles rolled out a brand new state-of-the-art feature for bus shelters. It's called Los Numbrita. Los Numbrita is a metal screen that's intended to provide shade for the thousands of people who ride the bus every day. The shade screen is about 2 feet wide, 10 feet tall, and it kind of looks like a curved,

teal, metal surfboard filled with tiny little holes. Right away, Angelina knows we're not happy. I was wondering why it was here because I was like, well, what's the point? Criticism has been swift online with people comparing this to a cheese grater. Many of the online complaints cited Lawson Brita's size. While the designers say Law Sambrida can provide shade for two or three people, critics say it doesn't look big enough for even a single person. And many people are furious about the cost. The La Sambrida prototype cost around $10,000.

Clearly, La Sambrida isn't perfect, but in Los Angeles, a little shade goes a long way. The controversy around Los Enbrita got me thinking about a conversation we had in 2020 with the journalist Sam Block. Sam is working on a book about the politics of shade and how shade, coverage, and LA has become one of the city's biggest hot-button issues. Today, we'll get Sam's thoughts about Los Amrita and whether the controversial shade fixture could actually be a good thing for shade starved Angelinos. But first, my conversation with Sam Block from 2020.

What did you notice about Los Angeles when you started walking around the city? What did I notice? I noticed that there was no one around. I noticed that the people who were around would have to position themselves in such a way to protect themselves from the sunlight. What do you mean? I noticed people waiting for the buses behind telephone poles.

I noticed people waiting behind the people, waiting behind telephone poles because there's only that small sliver of shade that people were protected from the sunlight. Why is shade so important? Los Angeles, like most every city in the world is heating up. There are some scientists who I speak to

who have found that in hot, dry, arid environments like Los Angeles, but also phoenix, that shade is the most important factor when it comes to human comfort, more than air temperature, more than humidity, more than wind speed. And there's a close relationship between human thermal comfort and mortality and illness and heat stroke.

If you don't have shade, if you're not protected from the sun, you can become dizzy, you can become disoriented, you can become confused, authorgic, dehydrated. If you are obese or elderly or pregnant that can tip into more dangerous things like heart attack or organ failure. And so what is the magnitude of the problem in LA? There are a few different ways of thinking about it. We can talk about shade in terms of tree canopy, which is a very serious problem. Los Angeles has terribly unequal tree canopy.

And by tree canopy, I just mean coverage. Let's say you're in outer space looking down on LA. You'll see parts of the city that are covered in green. And you'll see parts of the city that are not. They're baking an asphalt. And those two aty follow lines of wealth. It's a problem with tree canopy. It's a problem in terms of the built urban form.

Los Angeles is notoriously anti-density. Los Angeles has this image of itself as not being New York City, in fact being the anti-New York City. So sunlight and open space is a part of the culture. That's not necessarily a problem, but it becomes a problem when you can't escape it. So there are no tall buildings to provide, some measure of shade. I wouldn't go as far as to say there are no tall buildings. However, there are a few tall buildings. And there's space pretty far apart. Correct.

They're located in certain height districts downtown being one of them. And even some areas that city planners have designated to be taller neighborhoods, even today they're still fought and contested by neighborhood activists. So I've seen all pictures and I get a sense that Los Angeles used to be greener. Like there was a lot of shade So tell me how the city was designed and how it Developed into this. So time was Los Angeles was a prairie if you look at photos of LA from 150 years ago It's all grasslands and when it was settled by the Spanish downtown

Which was the original settlement was laid out according to law of the Indies. The city would roughly conform to a 45 degree angle, so you could have sunlight in the winter and shade and shadow in the summer. So explain the law of the Indies, what does this mean? The law of the Indies means build your cities at 45 degrees, basically. Really? Completely unlike the way we think of most American cities, which have this sort of north-south, east-west, very rich grid. So you have these original settlements that are laid out in such a way as to be able

to create shadow when you need it and also to bestow sunlight, also when you need it. Spanish architecture tends to have a very strong sense of natural comfort. So you'll see a lot of these kinds of missions and adobeies that have these internal court yards that are shaded. You'll have covered walkways, paseos, and even today you'll see a lot of this and Spanish revival architecture or outdoor malls that have goofy Spanish-ish names. Los Angeles was also in a way sort of a dusty,

old west town. So you think about these covered boardwalks, you think about large canvas awnings that are cooling people who are living outside and also cooling indoors, which at the time didn't have air conditioning. And another way that Los Angeles tried to stay cool was through rich, beautiful, kind of flamboyant,

not just tree canopy, but a syncretic, overwhelming variety of exotic, florent phantom. So during this period, there was a recognition of the environment and how to be comfortable inside of it. And when did that go wrong? Funny that you put it that way. Things started to go wrong after cheap electricity came down to Los Angeles with the completion of what's now called the Hoover Dam.

So you start to see the city rebuild itself and the new development becomes like we see today. You have controlled air conditioning, you have the automobile, which comes to dominate the city in the 30s and the 40s. And with the automobile, you just have a whole new way of seeing the city. The names of the streets are household words

translated into magic. Fabila stacks of freeways, tremendous turnwights. The city started to think about how to market itself and how to make itself see more attractive to outsiders And this is where you get palm trees Palm trees one essay is said were about as useful for shade as a telephone pole She hated them, but the city was enamored of them and interestingly you have different philanthropists and celebrities starting to think about And interestingly, you have different philanthropists and celebrities starting to think about trees as being a public good, but the palm tree in particular being one that doesn't just message L.A. as a kind of semi-tropical paradise, but also as Mary Pickford said, it's very good

for window shopping from the CD or car, because the tree trunks aren't that robust. So if you're driving down Symbolovard, you can see all the great stuff, because the palm tree is so narrow. So Los Angeles was also re-zoned in the 1930s to become a single family city. Los Angeles in order to sort of not pacify, not suck up, but to sort of remake itself from the image of the FHA decided that all new single family

homes had to come with a front and a side yard. So you start to create a lot of space around them. Los Angeles really starts to hate the idea of density. And so when you have this type of sprawling, not very density, how is the shade distributed? Unevenly. Shade is distributed to people who can afford it. If you go into these neighborhoods that were laid out to be wealthy residential enclaves, you have very wide sidewalks, and the strip of grass where you can tree plant, which is called the parkway, becomes four or five, maybe even ten feet wide. And when you have these wider parkways, you have a greater space to plant a bigger, thicker, leafier tree.

Okay, so the parkway is the area between the sidewalk and the road. Correct. And there's going to be pretty wide, and therefore, have trees with them. Correct. In other neighborhoods that have been redlined, that were designed as sort of worker housing, that were meant to sort of jam people in together, you don't have these kinds of wide residential sidewalks instead of what you have are very narrow sidewalks because these neighborhoods are designed to facilitate automobile passage. So if you have a narrow sidewalk, you don't really have the space to plan to thickly retrieve. Furthermore, it's been incumbent upon property

owners and renters to maintain this sort of semi-public space of the parkway. You would think that in a city, whatever is on the sidewalk, whatever is outside of the property line would be managed by the city. That has not historically been the case in Los Angeles. It's been incumbent upon property owners to water trees to maturity and to maintain them. If there's a tree there, it's because someone has taken it upon themselves to water it to maturity and to care for it.

So each part of that process, the design of where the sidewalk is relative to the street, the fact that a person of wealth could plant and maintain a tree, all these things cause more uneven distribution of shade trees. That's right. And I would also add that in some neighborhoods, I'm thinking about a neighborhood called Hancock Park, which is a flat neighborhood landlocked in the center of the city. There is nothing about it that naturally lends itself over to being a lush, verdant, tree-fistuned paradise.

But the neighborhood was developed as an exclusive wealthy residential enclave. And when that happened, the power lines were undergrounded. There is nothing in the way it is designed specifically to allow for tree growth. This is not the case in most of Los Angeles. So because of this lack of shade trees, there have been efforts to build in shade, especially around bus shelters, but it's been incredibly hard, according to your reporting. So like in your article, you talk about one bus shelter at Glastonal Park. Could you tell me about that and why it was so hard to put shade there?

It was hard because shade is a tripwire. In the instance of the Glacill Park Transit Island, you had a concern neighborhood resident and a neighborhood activist, maybe you'll call them a homeowner, who wanted to throw just a simple bus shelter over a space where she saw people naturally congregating. She ended up talking to an architect who said, let's not do a regular bus shelter. Let's throw some big shade sales in here. When that happens, you have to start thinking about how are we going to fix these shade sales to the ground. And when that happens, you have to start thinking

about what's underneath the ground. And you have water mains, you have underground utilities in order to upgrade a sidewalk or a transit island. You then have to start honoring newer regulations like the Americans with disabilities act, so then you have to start making curb cuts to make it wheelchair accessible. So you have to take care of all these other things before you can decide to do this very lightweight sort of low res fix. Right. The sort of the enemies of shade are not always bad guys in this case. ADA compliance is not a bad guy. No. Yeah, like curb cuts, not a bad guy. In this case, ADA compliance is not a bad guy.

No. Yeah, like, curbats, not a bad guy. Like, all these things are not bad. You know, it's not just sort of around sidewalks. LA doesn't have a lot of shaden at city parks either. So why is that? Why was this never considered valuable? It wouldn't go as so far as to say,

it was never considered valuable. Because I'm thinking about a park downtown called Purshing Square that up until the 1950s was a tropical paradise. It was incredibly shady. It was meant for people to kind of hang out and shoot the breeze. And after a while the business elite in the neighborhood decided, first of all, to install underground parking, which gets rid of the whole root system. So you can no longer plant thicker, denser tree canopy.

And part of the reason why Pershing Square was redeveloped in Shornhub its tree canopy is because Los Angeles is a city where residents are worried about crime, a city where residents are worried about homelessness. As I was working on this story, I came across multiple instances where LAPD had installed pull cameras in parks or in public housing projects. And I've been told about something called crime prevention through environmental design, which is this idea that we need to have increased visibility in public spaces. And you can go on Google Street View and go back five, six,

seven years. And you can see over time, when a pole camera goes up, a mature street tree goes down. So there's just all these selective pressures where other things are just more important. You know, like it, whether it's, I would call it somewhat the illusion of crime prevention. Correct. No one told me that it actually prevents crime. You know, like it, whether it's, I would call it somewhat the illusion of crime prevention.

Correct. No one told me that it actually prevents crime. What this detective told me was that it helps the police catch and prosecute criminals, not that it stops them. And then this preference for this underground parking, which makes shallow ground, which therefore you can only have trees that have ball root systems like palm trees. Correct. It just seems like everything is working against it, especially in this city. And so how do you think about how to balance these different factors and their value in an urban setting? Great question. There are a few ways to think about this. I mentioned that in Los Angeles,

it's homeowners and residents who are responsible for the maintenance and cultivation of street trees. Why does it have to be that way? Why doesn't the city decide that a public urban forest? Why isn't that a value? You might also think about the question of density. I spoke to an architect and what he told me is that maximizing floor space is the name of the game, which means if you only have so much space to work with, which developer is going to say, let's actually carve out some of our floor space to make an arcade or a portico. That's a tough sell. Right. So why doesn't the city properly incentivize developers to create these sort of semi-public shaded

environments behind the property line that are continuous with the sidewalk? And what about just plainland trees? I mean what is LA doing about just adding to the canopy in general? The city is trying to plant more trees. The city has a goal of planting 90,000 trees in the next few years. I am not sufficiently convinced that the city recognizes the infrastructural challenge to planting 90,000 trees. Because as we've been talking about the space in which you can plant a tree is limited. When you have things like an aeroside walk, or overhead power lines, or even regulations that limit or prohibit the planting of a street tree within 45 feet of a driveway, which, let's be real, that's practically all of Los Angeles.

That makes me think that the city is not understanding the complete wholesale reimagining of the street that's needed in order to plant 90,000 trees. So we've talked a lot about informal urbanism in the show, in sort of interventions. People could install umbrellas and canopies without permission to fix this kind of problem, just in their own neighborhood. Did you find evidence of people doing this and what is the reaction when this happened? People do it all the time. Particularly, I will add, in Latino neighborhoods. There's an urbanist named James Rohas,

who writes about Latino urbanism, and he has a pretty compelling theory that Latino residents of Los Angeles know how to use the shade, and he leads these wonderful walking tours world. He'll point out shade sales that have been connected between two garages and an alleyway for kids to play in,

because it's more comfortable under the shade. He'll point out these elaborate front yards where you have blue polytops, been connected between two garages and an alleyway for kids to play in because it's more comfortable under the shade. Or he'll point out these elaborate front yards where you have blue polytarp, just strong across a space, or maybe exotic trees that are sort of overflowing into the street. Well, that sounds great to me, but I get the impression that the city doesn't always see things the same way. What I did find is that in the private realm, those things are tolerated. When they step into the public and when they step onto the sidewalk, things become more

complicated. I write about a grassroots shade shelter on Figueroa and Avenue 26 in the Cyprus Park neighborhood near the LA River. And a barber named Tony Cornelho would not admit that it was he who made this really great fantastic shade shelter made out of like an Ibeam and a great tarp and a couple bus benches, but he told me that he recognized the need for people when they're waiting for the bus just to have some protection. Tony or someone had to take down this grassroots bus shelter because it was an obstruction in the public right of way. this grassroots bus shelter because it was an obstruction in the public right of way. The city processes 16,000 obstructions in the public right of way every year. If property owners,

if residents did not fear that the city would come after them, threatening them with fines, perhaps we would see more grassroots urbanism. I think it's pretty surprising to think of shade as a political inequity issue. I think it surprises a lot to think of shade as a political inequity issue. I think it surprises a lot of people. Tell me about your awakening of this and convincing people of it and just make your best case for what it is that you want people to think about when they think about shade in the city. Shade in a city is, to me, respect for people who can't afford to duck into an air-conditioned cafe or a lift when it gets too hot. Shade is to me an understanding that the world is changing and we want to protect citizens, the most vulnerable citizens, who can't

protect themselves. And it's also just nicer to be in the shade, it's cooler in the shade. I always walk on the shady side of the street. It's easier to see in the shade. I spoke to a scientist who said that direct sunlight is the kind of light that you have when you perform oral surgery.

That's not pleasant. No, dappled light is more like reading a book. Yeah. So I want my city to help me read a book. I don't want to perform a moral surgery. Thanks for coming in. I appreciate it. Yeah, thanks for having me, Roman.

When we come back, Sandblock talks about Lawson Brita and the future of Sh shade in Los Angeles. [♪ Music playing in background, in seems like a perfect solution to the problems Sam Locke mentioned in our interview. It's easy to install, and the city believes it could help thousands of people stay cool. The city says the shades structure is designed to help with gender equity, since most of L.A.'s transit riders are women. But for the most part, Angelino's aren't thrilled with La Sambrida, largely because of the underwhelming design. La Sambrida is a metal grate that shaped like a surfboard

and pock marks with tiny holes. Could it say it's too thin to provide any meaningful shade at all? After a social media backlash, La Sambrida became a national news story earlier this summer, and not for good reasons. A plan to provide more sun protection and safety for LA bus riders seems like a no-brainer right, but the new shades have left some shaking their heads. A Sam, welcome back and tell me, why are people so angry about La Sabrita? The frustrations with La Sabrita are, they emerge from a few causes, let's say. Los Angeles public officials have been telling bus riders and constituents and other Angelenos

for years that they want to create more shade. One example of this is with bus shelters. There are, I think, around well over 600,000 boardings on buses every day in Los Angeles. And only about a quarter of those bus stops have any kind of shelter from the sun. And as temperatures rise and heatwaves become more common. And as I would say rhetoric ramps up about the importance of taking public transit instead of driving for ecological and emissions related purposes. Many angelinos are finding that the street conditions just aren't conducive. They're not comfortable.

They don't entice people. People would so much rather be in the comfort of their own car instead of taking the bus because they're made to wait in the elements. So, Lawson Brita, when it arrived, was also couched in the rhetoric of gender equity. Now, I want to back up for a second on this because this is an important point. The Los Angeles Department of Transportation, one of the many agencies that controls, well, transportation, but also just various ways of getting around the city and various, let's just say, right of way jurisdictions has for a few years now been working with a design group to try to figure out how to better serve

its female bus riders. Ridership on buses and L.A. excuse female, women the way they ride the bus tends to be different from men, you know. The system is set up essentially to make sure that commuters can get to work from 9 to 5. But there are a lot of people in L.A. who maybe take the bus in the middle of the day. Maybe they're chaining more trips together because they are trying to run more errands, let's say, or they're picking up their kids from school. It's not really designed for them.

So gender equity is an attempt to address those problems. The reason that Lawson Brita caused this uproar, this Twitter revolt, is because the high-minded language of gender equity, the magnitude of the problem, let's say, of gender equity, not matched by this minuscule 24-inch screen bolted on the side of the road to this bus pole bike, to say that you're solving gender equity with this, is a little bit insulting. So, what are some of the good things about Lawson Breed? There must be some good things. Lawson Breedum makes shade, and any shade is better than none at all. I like to talk to a heat scientist at Arizona State University, her name is Arianna Medell.

She uses this heat index called the mean radiant temperature, which is basically, how much heat is crashing into your body from the sun, from the air, from all the reflected surfaces. And I called her after this thing blew up and I asked her about it. And she said, you know, what is wrong with all you people? Why are you all dumping on this? You know, what this does is it blocks direct solar radiation from hitting you. And direct solar radiation is the number one input in mean radiant temperature. So it helps.

It does create some cooling. Yeah. Yeah. I mean, we talked about this a few years ago. It's like people will line up behind a pole just to get a little bit of relief and a pole, you know, like something that's too intraswide. Someone describe that to me as the game we all play when you ride the bus in Los Angeles.

You queue up behind telephone poles or utility poles, you queue up behind someone else. I don't think it's very dignified having to sort of hide from the sun in these accidental shady spaces on the street, but people do it because it works, because you're getting the sun off your skin and there are a number of psychological

and physiological things that happen when you do that. Okay, so we're getting into the crux of this because this is exactly why I thought of you when I saw this thing. And to me, the shape of this thing is exactly the negative space created by the various regulations and bureaucracies of everything else surrounding it. There are many things stopping shade structures from being built. And some of those things are not necessarily bad things

in and of themselves. They're ADA compliance. There's a reason why a shade structure has holes because it's, you know, it needs to not collect garbage on it and water and things like that. So could you describe Lawson Breta in terms of the design constraints as you understand them. Sure.

Let's talk about the shape of La Sambrita, this skateboard popsicle, kind of oval shape. It couldn't be fatter, let's say. It couldn't be truly circular, like a parasol or octagonal like a stop sign because if it was too wide, this structure, which is again bolted to a bus pole, would blow over in the wind. So it had to be aerodynamic, let's say, for this specific purpose. It had to be perforated also for wind permeability,

right, so you don't want like a sail for the whole thing to just sort of get picked up and blown away. But the reason this screen is bolted to a bus pole instead of a fix to the ground where people are in the first place has to do with the tough knot of regulations around how the public right of way is used and allocated and controlled in Los Angeles, and almost none of it has to do with making shade.

ADA clearance is important. We want accessible sidewalks. For that reason, a narrow sidewalk, which UCLA researchers have found tend to be more common in POC neighborhoods in LA than white neighborhoods. Narrow sidewalks that were designed before modern ideas of accessibility are pretty much gobbled up by this need for ADA clearance, which again is a good thing. The solution to me seems to be, well, if you need more space, you can expand the sidewalk. You can work with the transit agencies to build into the road, to take some space away from cars and give it to pedestrians and bus riders, which, again, city leadership in Los Angeles says they want to encourage that kind of behavior.

Or the other thing you can do, which some transit agencies have done in San Antonio, is to get an easement on private property, and to take some of the private property that's next the sidewalk and give it to the public. The other reason why this shade structure is so spatially constrained is because there is this tendency amongst the many agencies in Los Angeles that control the public right of way, excuse me, not to work well together. And if you speak to people in the streets department, or somewhere else in public works, they all have their good reasons for wanting to work within their own agencies. They have not been properly directed to collaborate and coordinate on projects that holistically serve their constituents,

which are the public who, to be honest, don't really care who's jurisdiction sidewalk is. They just want an accessible place where they're not going to pass out waiting for the bus. So if you're only working, let's say, with the transportation agency, which has a very limited real estate that they had permitted in the sidewalk, you're only going to be able to work on that bus pole. If you want to work with the streets department, you have to get permitting, you have to go through another process. And then if you work with them,

you find that there are all these other obstructions that don't have to do with ADA, but have to do with say, the vision triangle and clearance, if there's a driveway, you can't be six to 10 feet with them that driveway, so drivers can see what's happening, so they don't run over pedestrian.

There's guy wire, holding up a overhead power line, you can't be building a bus shelter or planting a tree near there. All these other infrastructures that we know are important for cities. They all come well before anyone ever gets to say, I want to put a tree there. I want to put a bus shelter there. So it comes last or in some cases, not at all. I think part of the problem was that this was announced with this triumphant tone of achievement. When, as other people have since suggested to me, what if the press conference could have instead been,

look at what we're allowed to do because of the way we govern public space in Los Angeles. Look at this minor incursion that we are only allowed to do here. What if we could do something bigger? I mean, to me, it's pretty interesting because I think Las Ubrida is exactly the size of our desire to fix the problem. If you're criticizing its size, you should be criticizing the fact that this is all you get.

And that should be the story. Well said. Sam, this has been great. It's been great reconnecting with you. that this is all you get and that should be the story. Well said. Sam, this has been great. It's been great reconnecting with you. It's nice to see you again. Thanks so much. Yeah, thanks for having me.
