Jacobs was one of the first people to question the modernist orthodoxy of functional segregation in modern cities, and the attendant destruction of community and neighbourhood. Jacobs was especially sensitive to the value of a busy street as crowded, safe, egalitarian and prosperous. She understood that aggregation and diversity were the two drivers of urban dynamism…

Her book, The Death and Life of American Cities (1961) became the playbook for urban activists across the US.

The film also describes the unhappy example of the Pruitt-Igoe projects development in St Louis…

There is a lot of material about Pruitt-Igoe.

The development became derelict and was eventually pulled down…nowadays, the whole thing is viewed as an indictment of modernist renewal…

The destruction of Pruitt-Igoe provides a dramatic sequence in the documentary film, Koyaanisqatsi (1982). Philip Glass wrote the soundtrack.

Elsewhere, the dereliction of Detroit is also well documented. See, for example, Requiem for Detroit (2010).
