The following image is a geographic representation of Lafayette, Louisiana’s finances. It is from this excellent article by Charles Marohn.

What this 3D map shows is the city’s revenues and expenses by land parcel. The green areas are where the city is making a profit (revenues exceed expenses) and the red areas are where the city is operating at a loss (expenses exceed revenues). The height of each extrusion indicates just how much profit is being made and how much loss is being incurred.
The glaring takeaway from this study is this: not only are post-war land use patterns environmentally unsustainable, but they are also fiscally unsustainable. The tax base is simply not there to pay for the infrastructure that gets built alongside it.
They – the authors of this study – estimate that the infrastructure revenue gap for the median home in Lafayette is about $8,000 per year (median household income is $41,000). And yet despite this shortfall, it is common to look at infrastructure spending as a desirable economic stimulus.
The following paragraph really brings this point home:
“All of the programs and incentives put in place by the federal and state governments to induce higher levels of growth by building more infrastructure has made the city of Lafayette functionally insolvent. Lafayette has collectively made more promises than [it can] keep and it’s not even close. If they operated on accrual accounting – where you account for your long term liabilities – instead of a cash basis – where you don’t – they would have been bankrupt decades ago. This is a pattern we see in every city we’ve examined. It is a byproduct of the American pattern of development we adopted everywhere after World War II.”
Thank you Daniel for sharing this article with me.
If you only read one other thing today (besides my blog), I recommend you read Charles’ article. It’s called: The real reason your city has no money.
There is so much interest in cities right now and I think that is absolutely wonderful. Earlier today my friend Derek shared a video with me on Twitter called, The Future of Cities. It’s by YouTuber Oscar Boyson, who I recognize from some of Casey Neistat’s videos, but whose own videos I have never watched before.
I highly recommend you watch this video. It’s just over 18 minutes. If you can’t see the video below, click here.

It’s well-executed, a joy to watch, and packed full of information and ideas. There are soundbites from lots of well known urbanists (both living and dead). And I also love how Oscar crowdsourced ideas and content from cities all around the world.
The title of this blog post will make sense once you’ve watched the video.

We talk a lot about the greenbelt here in Toronto. Some argue that it’s squeezing the housing market and driving up prices.
But what about the yellowbelt? (Credit to Gil Meslin for the term.)
Here is a land use map of Toronto:

But what about the yellowbelt? (Credit to Gil Meslin for the term.)
Here is a land use map of Toronto:

The yellow areas are “neighborhoods.” They, along with parks, ravines, watercourses, and valleys, make up ¾ of the city’s land area. The Official Plan describes these areas as being “stable” – meaning they will see little physical change. Supply cannot adjust to demand.
I get why this is the way it is and I understand how difficult it would be change something like this. But let’s not ignore the impact that this land use constraint has and will continue to have on the housing market.
It’s the yellowbelt. Thank you Gil for letting me to steal the name.
