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
A passive beauty of right structure The human maker, working in unself-conscious matter, receives no worship from his creatures, since their will is no part of his material; he can only receive the response of their nature, and he is alone in fault if that response is not forthcoming. If he tortures his material, if the stone looks unhappy when he has wrought it into a pattern alien to its own nature, if his writing is an abuse of language, his music a succession of unmeaning intervals, the helpless discomfort of his material universe is a reproach to him alone; similarly, if he respects and interprets the integrity of his material, the seemliness of the ordered work proclaims his praise, and his only, without will, but in a passive beauty of right structure.
