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
The garden is a riot In conventional agriculture, vegetation is kept at the weed or herb level using energy to keep it cut, weeded, tilled, fetilised, and even burnt; that is, we are constantly setting the system back and incurring work and energy-costs when we stop natural succession from occurring. Instead of fighting this process, we can direct and accelerate it to build our own climax species in a shorter time. There is no attempt to form the garden into strict neat rows; it is a riot of shrubs, vines, garden beds, flowers, herbs, a few small trees, and even a small pond. Paths are sinuous, and garden beds might be round, key-holed, raised, spiraled, or sunken. Bill Mollison, Introduction to Permaculture 172. Garden Growing WildChef's Table: Jeong Kwan gardens
