00:00I'm Alexandros Washburn, former Chief Urban Designer of New York City, and I'm here to answer your questions from the internet.
00:06This is City Planning Support.
00:08City Planning Support
00:13At UrbanistOrg asks,
00:15How can cities make bike lanes safer?
00:18The answer might surprise you.
00:19You know what we found out in New York?
00:20The best way to make a bike lane safer on, say, 6th Avenue?
00:24Park cars next to it.
00:26We moved the parking lane away from the curb and put the bike lane on the sidewalk side of the cars.
00:32Now those parked cars act like a buffer.
00:35ERWNN asks,
00:37Is the New York City subway really that bad compared to other world city metro systems?
00:42Short answer is yes.
00:44It's a great system in the way it's been laid out and how many miles it is.
00:49It's one of the world's largest systems.
00:50It hasn't been maintained very well.
00:52And one of the reasons is that the city that never sleeps, we never shut down the subways at night to fix them.
00:57The cumulative effects of lack of maintenance or sleep for our subways have really caught up with us.
01:02And things are not good right now.
01:04It's also interesting if you go to another city with a major metro system, say like Moscow,
01:08you will be amazed at how fast the trains run and how fast the escalators go.
01:13There's just kind of a sense of pace that we seem to have lost.
01:17We have neglected our subways and we have a long way to go to make them halfway as good as many cities around the world.
01:24At DeepYearning asks,
01:26Guys, can anyone help me understand something?
01:28Is rent control bad or good?
01:30Like what are the pros and cons of it?
01:32Rent control is a tool to make cities more affordable.
01:36It should be a good thing.
01:37Some places in the world where rent control is actually a national policy,
01:41say Germany, has a pretty stable, solid housing market.
01:45It seems to work.
01:46But then again, rent control in other places has different effects.
01:51Sometimes people don't want to build a building if they know it's going to be rent controlled in the future.
01:56Sometimes banks don't want to give a loan on a building that will be rent controlled in the future
02:00because nobody knows what the future will bring and development starts drying up.
02:05Why can rent control be workable in one place and then have a chilling effect on another?
02:11And you know, I think the answer is actually societal.
02:14You know, places where it works best are relatively homogeneous societies.
02:18It becomes a policy tool, not a discrimination tool.
02:21Keep rent control in your toolkit.
02:24But there are other tools like rent support vouchers or simply increase your supply.
02:30At InfoSecTaylor,
02:32Okay Boston folk, you win.
02:34This is the worst city I have driven in.
02:36You get the gold medal.
02:37Why would you let your city planners do this to you?
02:40As we all know, Boston was planned by cows.
02:43Essentially the streets of Boston follow 17th century cow paths that crisscrossed it.
02:49It's as simple as that.
02:50Sometimes even the planners aren't at fault.
02:52At PKCG5 asks,
02:56Why so green Singapore?
02:58Singapore, one of my favorite cities.
03:00A green city because it made a decision at its very start to be a city in a park.
03:05Everything about it is geared towards bringing the nature into the city and using nature like infrastructure.
03:11Part of their main issues is of course the very hot climate.
03:15So nature becomes a way of creating a microclimate.
03:18So the plants have a cooling effect on the city.
03:20In fact, they're little solar panels.
03:22They take solar energy and they turn it into biomass.
03:24And that biomass pulls the energy out of the microclimate system.
03:29And beyond that turns it into shade which then protects the pavement itself from getting over hot.
03:35And it creates oxygen to boot.
03:37It's a win-win-win.
03:38Singaporeans are pretty smart.
03:40Ah, Damon Prince of Corn.
03:42What airports are perfect, close to perfect, or otherwise great?
03:47So Singapore is the best because anytime they have to figure out how many square feet do we need for say security,
03:53they double it, triple it, quadruple it.
03:55They know that everything is growing.
03:58So they look ahead.
03:59Then they ask, are people bored in between flights?
04:03The answer was yes.
04:04So they built the most incredible nature park inside of an airport with hundreds foot tall waterfall,
04:11incredible jungle trails you can take, shopping, dining.
04:15It becomes a place.
04:17It would be good for us in the United States to start thinking about it that way.
04:21Let's make an airport you actually will be delighted to visit.
04:24All right.
04:25EnergyPer250MLServe asks,
04:29Are there any cities that are really doing everything or almost everything right in regards to urban planning?
04:35The answer is yes.
04:37And that city is Paris.
04:39They do everything right.
04:41And it's very annoying.
04:42Bikeshare.
04:43They did it first.
04:44New York.
04:45We love our city bikes, but we stole the idea.
04:47The High Line.
04:48They did it first.
04:49It was called the Promenade Plantée.
04:51We stole it.
04:52The next one that I'd like to steal from them is that they've made a network of streets that are meant to get to schools.
04:58So they're like super safe streets.
04:59Streets where you'd be happy for your kids to walk on their own or bike on their own to school.
05:04What a great idea.
05:05Let's steal that one too.
05:07AtEndava asks,
05:09What makes a smart city smart?
05:11A smart city is a city that makes the right decisions.
05:14Now the best cities right now for smart are the ones that have great databases because the data helps you make the right decision.
05:20An example of data a smart city would use are traffic flows.
05:24Where are all the cars right now?
05:26Where are they going to be?
05:27What are the impediments?
05:28How do we open up?
05:29How do we change the patterns?
05:31It's the ability to respond in real time that makes a really good smart city really smart.
05:37Reddit sub admin,
05:38What is the biggest reason America is so car dependent?
05:41The one thing that says it all is a phrase from the 1950s.
05:45What's good for General Motors is good for America.
05:48The United States, right at the beginning of its largest growth spurt, decided that cars were the answer.
05:56Everything in American city planning was dimensioned to a car.
06:00How far it turns, how many parking spaces you have to have, how wide the streets are, etc.
06:05Once you make those decisions, you can't change them.
06:07It's called path dependency.
06:09To change that requires a lot of ingenuity.
06:12We talked earlier about how you put bike lanes and parking lanes together.
06:15But it's going to require thinking outside the box, thinking outside the car.
06:21Lianen salary say,
06:23Not sure why they aren't turning the current empty office blocks into small apartments.
06:28Don't we need housing more than offices?
06:30Indeed we do.
06:31And it's totally doable except that we stand in our own way.
06:35We've created an incredible framework of rules that a building has a specific use and only one use.
06:42What are some of these rules that stand in the way?
06:45There's light and air.
06:46It's the first one.
06:47If you're an apartment, you need to be able to open the window.
06:49And for some reason, somebody in the 60s or 70s came up with this idea that if you're an office, you don't need to open a window.
06:55Now, that's not the way it is in Germany.
06:57But in America, it's that way.
06:59So you've got all these hermetically sealed buildings.
07:01And now we've got to get past that.
07:02Open the window.
07:04And then people say, well, you're going to be too far away from a window if you fill an office building with apartments.
07:09You don't have to have the apartment go all the way back to the elevator.
07:13What if it stops 30 feet back?
07:15Which is the current rule for how far away you can be from an open window.
07:19And after that, why not make some space where we can perhaps have some vertical farming?
07:23Sure, you can put storage or bill of storage.
07:25But why not grow some vegetables?
07:27Okay, Stata6738 asks, what do you think are the current and future challenges that affect urban planning?
07:34It's declining population.
07:36We're not there yet.
07:37Certainly not in America.
07:39Certain places are, like Bulgaria, for instance, where there are a million more apartments than there are people.
07:45The movement from the countryside to cities is starting to slow down.
07:51And we've been in this frenzy of city building.
07:53And we haven't done a very good job with it.
07:55The biggest challenge for urban planning, looking into the 50-year future, I'm not talking about next year,
08:00is what are we going to do when population starts to plateau and then decline?
08:06And then all the pressure on building more and new and better is not there.
08:12And we have to deal with what we have.
08:14At Aaron Rose Glass, what if public libraries were open late every night?
08:20And we could engage in public life there instead of having to choose between drinking at the bar and domestic isolation?
08:26Great suggestion, but I wouldn't limit it just to public libraries.
08:29Every city has got to have public space.
08:31If you don't exclude people, everyone comes together.
08:34Whether it's your library or your park or in the ideal world,
08:38every street that you can walk down should be a place where you can respectfully interact with your fellow citizens.
08:44And that interaction is what builds up sociability.
08:47At Wildflower Milk, whoever made tolls a thing, I just want to talk.
08:52Like, why do I have to pay to drive around the city I live in?
08:56What the ****?
08:57Who pays?
08:58Who pays for the roadbed?
09:00Who pays for maintaining the streets?
09:02Can you pay a toll?
09:04Can you pay the full cost of driving around your city?
09:07Well, we've never done that in America.
09:09We've always hidden the true cost of driving in other budgets and not passed them on to cars.
09:14There's always been one toll in America, and that is the highway gas tax.
09:19But that is an absurdly small percentage of every gallon of gas you buy.
09:24Congestion pricing, tolling cars in certain areas of the city,
09:28that's a way to try to recover some of the costs of maintaining a road network in the city
09:34and pass them on to the people who actually are using them, the drivers,
09:39and not to bury them into the municipal tax budget, which otherwise could go to schools or daycare.
09:46At Eddie345 asks,
09:53Someone who has been in 51 degrees Celsius summer heat in Dubai, I know what you're feeling.
09:57The three things you've got to do.
09:59Number one, you can adjust your clothing.
10:01There are certain standards of kind of international dress, you know, suits and shoes and stuff like that.
10:06Forget about those in the 51 degrees.
10:09Open-toed shoes are fine.
10:11Two, adapt your hours.
10:12Don't go out in the middle of the day.
10:15Dubai at nighttime can also be pretty hot and humid.
10:18So that gets me to the third one, and that is humidity control.
10:21You know, we've been so focused on air conditioning and bringing the temperature down,
10:25but you'll find that a lot of what makes you comfortable is a certain level of humidity relative to a certain temperature.
10:30Dehumidification takes less energy than air conditioning.
10:33And guess what it makes?
10:35It makes water.
10:36And who needs water?
10:37Oh, the Gulf states need water.
10:39As you pull that humidity out of the atmosphere, you make yourself more comfortable,
10:43and you create for yourself some potable water.
10:46C. Sosa asks,
10:50My answer is, maybe you don't.
10:52L.A. is a much more progressive city than we understand from urban planning tours because it is what's called a polycentric city.
11:00Yes, L.A. has huge traffic problems.
11:03But over time, different neighborhoods have started growing into places.
11:07Now L.A. is becoming a city of cities.
11:10Once you do that, you can start not needing a car as much.
11:14L.A., everybody loves to hate it for the traffic, but it may have a thing on the future
11:19where if it succeeds in connecting its nodes through things other than cars, then it's going to thrive.
11:24And we might be looking to L.A. in the future as an example, not a punchline.
11:28That's it. That's all the questions.
11:30Hope you learned something.
11:31Till next time.
