Are Sponge Cities the Flood Control Fix We Need?

Are Sponge Cities the Flood Control Fix We Need?

Author: Strong Towns August 27, 2025 Duration: 40:12
Join Abby and guest John Pattison as they dive into the benefits and drawbacks of "sponge cities," cities that incorporate natural features like wetlands into their stormwater management infrastructure. Is this method more resilient in the long term? Do the benefits outweigh the massive cost? How does this relate to the incremental, bottom-up approach? They’ll cover all this and more in today’s episode of Upzoned. ADDITIONAL SHOW NOTES “‘Sponge City’: Copenhagen Adapts to a Wetter Future” by Paul Hockenos, Yale Environment 360 (July 2025).

Each week, Upzoned takes a single, pressing story from the world of urban development, municipal policy, and community economics and holds it up to the light. Hosts Abby Kinney and Chuck Marohn of Strong Towns, sometimes joined by a guest, don't just skim the headlines. They dig into the nuances of a specific zoning decision, a new infrastructure project, or a shifting demographic trend, asking what it reveals about how we actually build our cities, towns, and neighborhoods. The conversation is grounded in the practical, bottom-up philosophy of the Strong Towns movement, making complex topics accessible and immediately relevant. This isn't a broad news recap; it's a focused, thoughtful dissection for anyone curious about why their community looks and functions the way it does. You'll hear informed debate, critical analysis, and a persistent questioning of conventional wisdom, all aimed at understanding how we can create places that are financially resilient and genuinely enriching for the people who live in them. Tune in for a deeper, more substantive take on the stories that shape our shared spaces.
