"If you have a property in the city, you should not leave it empty."
03/17/21 • 31 min
New York City is at a crossroads.
So say Carlo Ratti and Saskia Sassen in a recent Bloomberg CityLab article, “The Case for a Duty to the City.” Many wealthy residents are fleeing New York City for the suburbs. Perhaps a third of the small businesses that closed down last year won’t be returning. And, according to a recent survey, executives report plans to reduce office space by 30%. Ratti, the director of the Senseable City Lab at the Massachusetts Institute of Technology, and Sassen, a Professor of Sociology at Columbia University, say New York has a choice right now:
If we do not act, we might end up with a metropolis of zombie neighborhoods, engulfed in a downward spiral of struggling businesses catering to increasingly empty offices. However, if we implement the right policies and foster a quick restructuring of real estate assets, the looming disruption may give us an opportunity—to test out urban policies we have never had the will or the necessity to imagine, much less implement. With familiar options destabilized, the times are inviting us to be innovators.
To revitalize the city they suggest policy changes like vacancy taxes, more flexible zoning regulations, and working with governments and nonprofits to provisionally repurpose properties. They make the case that owners and tenants have a “duty” to the city: If you have a property in the city, you should not leave it empty. Why a duty? Because a city “is not just an agglomeration of real estate assets; it is primarily a repository of human vitality, without which those assets would be worthless.”
Ratti and Sassen’s article is the topic of this week’s episode of Upzoned, with host Abby Kinney, an urban planner in Kansas City, and regular cohost Chuck Marohn, the founder and president of Strong Towns. Abby and Chuck talk about the challenge of transitioning the financial and regulatory environments in a place like New York, the pros and cons of a vacancy tax, and the systems that encourage land speculation. They also talk about the powerful rhetoric of “duty,” and how it might help towns and cities—including, but certainly not limited to, New York City—get unstuck and start building real prosperity.
Then in the Downzone, Chuck recommends Uprooted, the new book by Grace Olmstead. (Olmstead was our guest on Monday’s Strong Towns podcast.) And Abby talks about an upcoming vacation.

How a Small California Town is Charting Its Own Course to Energy Resilience
Recent winter storms in Texas and elsewhere around the United States are just the latest example of how vulnerable cities and residents are to sudden shocks to their electrical grids. Last summer, about half-a-million homes in Californians experienced rolling blackouts. Wildfire concerns last year also prompted Pacific Gas & Electric—or PG&E, which provides electricity and gas to 16 million Californians—to make “preemptive power shutoffs.” This was in response to lessons learned from the 2018 Camp Fire, which was ignited by PG&E power lines, and which killed at least 86 people.
Big utility companies like PG&E have a near-monopoly in their respective regions. What alternatives do cities have—if any—to providing safe, reliable electricity to residents and businesses? The farming town of Gonzales, California (pop. 9,000) is finding a way. As described in a recent story on KCRW, Gonzales is creating California’s largest multi-customer microgrid. Microgrids are local power grids that can be either separate from, or connected to, the larger grid. “In California,” says KCRW contributor Joe Mathews, “[microgrids] are seen as tools to make electricity service more resilient and to better integrate renewable energy sources, like solar and wind. But efforts to establish microgrids face complex obstacles, including scarce financing, regulatory barriers, and utility opposition.” He continues:
What distinguishes Gonzales is how the town is bringing together different entities—a technologically advanced microgrid developer, agricultural businesses, and a municipal energy authority—to surmount those obstacles. If the microgrid launches successfully next year, Gonzales could provide a model for other communities, especially those in outlying areas poorly served by the existing grid.
In this episode of the Upzoned podcast, host Abby Kinney, an urban planner in Kansas City, and regular cohost Chuck Marohn, the founder and president of Strong Towns, talk about why cities and residents are looking for resilient alternatives to the big utility companies. They discuss the history of how electric power went from something managed locally to the more centralized systems we have today. And they talk about the disconnect between the producers of electricity and the users of electricity, whether more cities should pursue the course being charted by Gonzales, and the role individual producers—for example, folks with their own solar panels—play in energy resilience.
Then in the Downzone, Chuck describes a book he’s reading by a former insider at the Federal Reserve. And Abby talks about binge-watching a show considered to be one of TV’s best ever.

How People-Centered Is Toronto's "People-Centered" Vision?
Are you a Strong Towns member? If so, don’t miss the announcement inside the podcast for a fun, free event with games, a live recording of Upzoned, and, apparently, chocolate milk and Diet Mountain Dew.
Last May, we devoted an episode of the Upzoned podcast to talk about the decision of Sidewalk Labs (a subsidiary of Google’s parent company, Alphabet) to pull out of Toronto’s Quayside development. The project, first announced in 2017, had intended to transform 12 acres of industrial land on Toronto’s waterfront into a “high-tech utopia,” complete with “mass timber housing, heated and illuminated sidewalks, public Wi-Fi, and, of course, a host of cameras and other sensors to monitor traffic and street life.” The project was controversial from the start—not least because of privacy concerns. Then last spring the CEO of Sidewalk Labs announced the company was no longer pursuing the Quayside project due to “unprecedented economic uncertainty.”
Earlier this month, the City of Toronto released a new RFP for the 12-acre site. The new vision is not for a neighborhood reimagined “from the internet up”, but rather, according to a recent article in The Guardian, a “people-centred vision” in which “affordability, sustainability and environmentally friendly design are prioritized over the trappings of new and often untested technologies.”
Upzoned host Abby Kinney, an urban planner in Kansas City, and regular co-host Chuck Marohn, the president of Strong Towns, return to talk about Toronto’s new plans for Quayside. How “people-centered” is the new vision? In fact, how different is the vision, really? The wooden skyscrapers and heated sidewalks may be gone, but what remains—the underlying chassis—appears the same: building all at once and to a finished state. Abby and Chuck talk about why Toronto seems stuck in the big planning mindset and what happens when mega-projects get new marketing brochures. They also discuss a truly people-centered approach: a city shaped by many hands, and projects that can be adapted, re-used, and are good for more than just one thing.
Then in the Downzone, Chuck talks about an audiobook he’s listening to on the story of human language. And Abby recommends the podcast miniseries Nice White Parents.
