Zoning for diversity As production becomes increasingly clean and knowledge-based, as our urban economies tip dramatically to service industries, as racism and ethnic animosities ebb, and as the model of mixed use becomes more and more persuasive and visible, cities are in a position to dramatically rethink zoning as a medium for leveraging and usefully complicating difference, rather than simply isolating it.

The greatest flaw in city zoning Raskin, in his essay on variety, suggested that the greatest flaw in city zoning is that it permits monotony. I think this is correct. Perhaps the next greatest flaw is that it ignores scale of use, where this is an important consideration, or confuses it with kind of use.

The air doesn't know about zoning boundaries Work uses suggest another bugaboo: reeking smokestacks and flying ash. Of course reeking smokestacks and flying ash are harmful, but it does not follow that intensive city manufacturing (most of which produces no such nasty by-products) or other work uses must be segregated from dwellings. Indeed, the notion that reek or fumes are to be combated by zoning and land-sorting classifications at all is ridiculous. The air doesn’t know about zoning boundaries. Regulations specifically aimed at the smoke or the reek itself are to the point. Jane Jacobs, The Death and Life of Great American Cities zoningregulationsseparation
Wonder Plots Working from first principles, and working in a highly organized way seem to come naturally to him, but his personal design process is much less structured than the results might suggest. Although he can tightly organize his team and run a complex racing organisation, his personal ways of designing are relatively unstructured, based on annotated, thumb-nail sketches. ‘I don't sit down and say, OK, now I've had the idea, let's see, this is a solution, these are the different ways to go, if I do this, and do that; I do lots of scribbles just to save it, before I forget.’ Gordon’s design process is based on starting with a quick sketch of a whole idea, which is then developed through many different refinements. ‘I do a quick sketch of the whole idea, and then if there's one bit that looks good, instead of rubbing other bits out, I'd put that bit to one side; I'd do it again and expand on the good bit, and drop out the bad bit, and keep doing it, doing it; and end up with all these sketches, and eventually you end up throwing ninety percent of these away.’ He also talks to himself - or rather, writes notes to himself on the sketches; notes such as ‘rubbish’, ‘too heavy’ or ‘move it this way 30mm.’ Eventually he gets to the stage of more formal, orthographic drawings, but still drawing annotated plans, elevations and sections all together, ‘Until at the end of the day the guys at Brabham used to call them “Wonder Plots”, because they used to say “It's a wonder anybody could see what was on them”!’ Nigel Cross & Anita Clayburn Cross, Winning by Design: The Methods of Gordon Murray The Design Squiggle
