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
Forces of conflict A pattern which prevents us from resolving our conflicting forces leaves us almost perpetually in a state of tension. For, if we live in a world where work is separated from family life, or where courtyards turn us away, or where windows are merely holes in the wall, we experience the stress of these inner and conflicting forces constantly. We can never come to rest. We are living then, in a world so made, so patterned, that we cannot, by any stratagem, defeat the tension, solve the problem, or resolve the conflict. In this kind of world the conflicts do not go away. They stay within us, nagging, tense…The build-up of stress, however minor, stays within us. We live in a state of heightened alertness, higher stress, more adrenaline, all the time. Christopher Alexander, The Timeless Way of Building Fucking up the world
