This week friend of the pod Aaron Lubeck joins to interview me about the origins of this podcast, and in particular my piece: Toward a New School of City Builders. Thanks for listening! Seth Zeren: Hello and welcome to The New School for City Builders. I’m your host, Seth Zeren, a recovering city planner turned neighborhood developer in Providence, Rhode Island. Joining me today is Aaron Lubeck, an incremental developer and designer in Durham, North Carolina. Aaron has taught historic rehabilitation and sustainable design at Duke University and with the Incremental Development Alliance. He created the podcast for the National Town Builders Association, and he’s probably more responsible than anyone else for pushing me to start this podcast. In today’s conversation, Aaron will also turn the tables and interview me about the origin of this podcast and the need for a new school for city builders. Aaron, welcome. Aaron: It’s great to be here. Thanks for doing this, for having me on, and for getting this thing rolling. It’s exciting to see this idea progress through all its iterations. Seth: It’s so great to have you here. Out of that introduction, I should say I blame you most for this podcast — my wife too, probably. How did you talk me into doing this? Aaron: In fairness, it’s been a few years. I remember sitting with you in the airport in Cincinnati, both of us getting excited about this idea — the need for a new school, something more than a weekend workshop or a day class. There needs to be a place to send 18-year-olds who really want to build cities, and there just isn’t one yet. Some places get close, but there’s no single place. So many kids want to do this in some form — work on cities, build cities, solve problems — and there’s nowhere to go. There’s so much cool stuff happening, from what’s going on in Florida to the City Makers Collective and beyond, but there clearly needs to be a bigger vision. I think it percolated long enough, and you finally said, “I need to get these ideas out.” And here we are. Seth: That was sort of two thoughts. One — this is a good advertisement for coming to the Congress for the New Urbanism, because the most important ideas usually come from sitting in an airport at the end of a trip, or taking a long walk after lunch with a friend. That’s where the real ideas percolate. For anyone coming to CNU, I’ll be there in Arkansas in a couple of weeks. I think part of what drew me to this was a gap. I’m part of these one-off conversations with people about building new institutions, changing how we teach, creating new programs — but there wasn’t a forum bringing those conversations together. On the other hand, I keep meeting young people — 18, 22, 25 years old — who’ve discovered they’re interested in city building somewhere along the way. We don’t teach any of this in high school, so people stumble into it: watching YouTube videos, reading a book, going on vacation. There’s some inciting incident. I keep meeting people who got radicalized watching Not Just Bikes, then went to architecture school, then realized architecture school wasn’t doing anything like what they expected. So there’s a real need for a forum where young people can learn how to make the most of their education and what to look for in a program. Aaron: Wholeheartedly agree. And to reiterate — I’m so glad you started this podcast, because it’s narrow and specific. The ones that make a difference are usually on a narrow topic, and there’s nobody in this space. There are plenty of podcasts on urbanism, walkability, design, affordability — but nothing like this. This could evolve into a space people come to when they’re frustrated with the pedagogy — professors, students, families with kids interested in this stuff. So much has happened since Cincinnati, going on two or three years ago now. Brett Jones’s work in Florida, Nathan Norris’s community college program — which hits some of the gold standard we’ll discuss today — Will McCollum’s summer program in Charleston, which sounds incredible, and Ruben Hanson, who has a great podcast and is getting into teaching in Europe. I see all of these as green shoots. Before you answer — I know we’re doing a bit of an experiment here. Given my background hosting the Town Builders Podcast for the National Town Builders Association, a good way to plant the flag for this podcast and your website is for me to interview you, so you can lay out your thesis: what’s the point of dissatisfaction, and what do we do about it? So — Seth, why do you think we need a new school for city builders? Seth: Thanks, Aaron. A lot of this comes from my own experience. Like I said, we all have our breakthrough moment. For me — I’d studied climate science, was a geology major in undergrad, was thinking about grad school and PhDs. I’d also picked up a bug for sustainable design and green building. So I took an early online course — this was around 2006 or 2007 — through the Harvard Extension Program, on the history of the American city. Great course. I read Jane Jacobs for the first time, studied the history of American cities. Aaron: It’s her birthday today, incidentally. Seth: It is her birthday today. Happy birthday, Jane Jacobs — or as we like to call it, Urban Renewal Remembrance Day, when we remind ourselves of the dangers of hubris. Go put a wreath on a highway overpass somewhere. Say sorry. So that course got me excited about city building, but I was intimidated — I didn’t know how to draw, had no portfolio, didn’t think I could go to architecture or planning school. I was a scientist. So I went to a graduate program at Yale where I was technically enrolled in the environmental school but spent half my time secretly taking classes in architecture, law, and business. I got really interested in zoning and land use regulation, and ended up taking a job as a city planner for the City of Newton, Massachusetts — writing zoning amendments, reviewing projects. While on city staff, I started to see the whole city-builder ecosystem: on the city side, planners, engineers, police and fire, DPW; on the private side, civil engineers, architects, developers. Watching all these pieces interact, I was struck by the fact that we don’t understand each other. We don’t even speak the same language — different jargon, different goals. Aaron: There’s a stunning lack of curiosity sometimes. The silo-ization keeps it that way — “I don’t understand them, but it’s not my job to.” Seth: Right. Some people think their job is regulatory compliance — just follow the rules, whatever they are. Some developers just want to make as much money as possible and don’t care about long-term implications. Not everyone’s like that, but I’ll tell a story — we were working on improving a neighborhood village center, trying to improve walkability and pedestrian safety, and we kept hitting a wall with the city engineer. Every time we tried to change something, it was “this doesn’t comply with the regs” or “we don’t have the warrants for a stop sign here.” And we’d say, well, we’re trying to improve safety — what would you suggest? “Nothing, because none of these things meet my book.” And we’re left thinking, what are we all doing here? Aaron: Right — “the rule book says this.” There’s a reputation in every city for which profession is the most rigid and unbending about doing reasonable things, and engineers often get that label. There’s an understanding of the broader vision, but “that’s not my job, and the rule book says something different.” There are interesting proposals to fix this — calls for some kind of benevolent overseer who could cut through it — but really, it’s the silo issue you write about so eloquently in the piece we’re discussing today. Seth: Part of the problem is that cities are genuinely complex and do require specialized expertise. I don’t know how to make sure sewers drain correctly — someone needs that skill, and it’s a specialized job. There are a lot of these specialized roles. But look at how we train specialists: architects are in the school of arts and architecture, planners are in the government school, civil engineers are in the engineering college, developers are in the business school, activists are in sociology. Nobody talks to anybody, nobody shares the same goals. You can get an engineering degree without learning anything about urbanism. You can get an architecture degree without learning anything about development. You can get a development degree knowing nothing about design. These silos start early in people’s technical training, and they persist — you get your first job, and on some paths you pursue licensure, which requires apprenticing at an existing firm or having an accredited degree. Part of the reason the civil engineering curriculum has nothing about how a city works is that it’s not in the accreditation standards — there’s no room for it. You take four semesters of calculus but zero semesters on the purpose of a city. That’s driven by accreditation, so it’s very hard to change at the ground level. People arrive in specialized jobs with no sense of the whole team. It’s like a football team where everyone does their own thing with no shared playbook, language, or goals. Some specialization is fine and necessary, but without a shared framework, you get chaos — which is exactly what we have. Our cities aren’t functioning in a coordinated fashion. Aaron: This is getting a bit ahead of the horse, but two of your proposed solutions are a common core curriculum — giving people a shared liberal-arts foundation in what a city is and why it matters — and leadership training. At the end of the day, teamwork requires leadership. On a football team that’s obvious, but I don’t kno
