I love a bit of design history. Whilst in the Mission yesterday I picked up this gem from 1970 at Farnsworth Mercantile on Valencia. It's part of an urban planning study that was carried out by the city in the late 60s and early 70s, eventually being adopted in 1972. There were 8 reports and this is Preliminary Report No. 5 Urban Design Principles for San Francisco (July 1970) by Thomas R. Aidala. When I saw it I couldn't resist it. Square format, that beautiful big 5 on the cover and most of all it's about design principles.
It looks like it belonged to one of the consulting or committee architects; Henrik Bull of BSA Architects as there is a newsletter from 1999 tucked inside address to him containing an article on the study.
Here's a few spreads from the report. I love the spiral binding (although it's a little tight) and the heavier paper section divides.
It's chocked full of these great drawings and diagrams explaining problems and approaches to improving the city, based on the principles.
The design principles are pretty cool too. Even the simple explanation to what 'design principles' are is pretty good. Here's a pic of them (will transcribe when I have more time).
Here's the article about the project from the August 1999 SPUR newsletter (sorry about the low quality).
