The Evolution of Urban Planning in 10 Diagrams

A new exhibit from the San Francisco Planning and Urban Research Association showcases the simple visualizations of complex ideas that have changed how we live.

Le Corbusier’s plan may not have had such power if he hadn’t put it on paper. The French modernist architect wanted to reform the polluted industrial city by building “towers in a park” where workers might live high above the streets, surrounded by green space and far from their factories. His idea was radical for the 1930s, and it was his diagrams of it that really captured the imagination.

"It swept everyone along," says Benjamin Grant, the public realm and urban design program manager for the San Francisco Planning and Urban Research Association. "They were such compelling drawings of such a compelling idea."
