Places Journal published Hippie Modernism: How Bay Area design radicals tried to save the planet, by Greg Castillo.
On a related note back in 2014 I started a thread over at Archinect, asking for reading suggestion for –
“books/essays which explore links between participatory-design/performance and political and ecological engagement in architecture and urbanism

Closest i could seem to find was some works by Simon Sadler out of UC Davis…”
