Housing Collapse – An Aerial View

Posted in Economics, General Architecture by michaelwalch on 22 September, 2010

Firstly, to be my friend or read my blog you must listen to NPR’s Planet Money.  Last week, the Planet Money team was tracing the origins of Toxie, the ‘toxic asset’ (mortgage-backed security) that they bought a while back in order to experience first-hand the major story of the economic downturn.  Toxie is essentially a bundle of home mortgages, so while perhaps no other investor has thought to do this, the NPR team has been looking for the actual houses associated with their complex financial instrument – which brought them to Florida, where they discovered not only the houses they were looking for, but entire neighborhoods from a previous housing bubble in Florida.  Read the blog post and listen to the podcast, then compare the maps below:


Lehigh Acres, FL

This is the area mentioned in the podcast.  You can find out lots more about it at the website of Spikowski Planning Associates, who have done extensive planning for reusing the abandoned lots.  “[Lehigh Acres] was subdivided into about 135,000 lots, over 121,500 of which remain vacant.” – from Spikowski, W. M. and Stroubd, H. B. “Planning in the Wake of Florida Land Scams” available as a PDF on their website.

Salton City, CA

This was posted in the comments on the blog page, and looks to be a similar story to the Florida example.

These neighborhoods were built as land investments (from around the 1970s) so streets were built (and named) but not houses.  The land was cleared but was never built upon, and in most areas has grown back.  This is in sharp contrast to neighborhoods of foreclosed homes, where houses were built but then abandoned (or, as the podcast reports, no one ever moved in in the first place).  The question of what to do with this land is huge in every dimension – the sheer amount of vacant space within (albeit suburban/rural) cities, their value not only to the local owners and/or municipalities but to the world economy through the various financial instruments that caused their associated booms in the first place, and their environmental impact (one point emphasized in the podcast was the array of animals who had moved in to the abandoned houses).


I’m working on a comparable map insert for the more recent foreclosure crisis.  This is largely a more subtle, on-the-street issue where you see unmaintained yards and homes – it’s more abstract in an aerial view.  One place to start is the HotPads Foreclosure search map.
