ch.13

Part 3 of the book” the death and life of great American cities” is about forces of decline and regeneration. It covers chapter 13 to 16. In these chapters, Jane Jacob mentions several problems that can influence the diversity of cities but they possess the 4 necessary conditions. The first chapter of part 3 is”the self- destruction of diversity”. The self destruction happens in outstanding and successful places whatever streets or whole district. “Diversity grows in a city area because of economic opportunity and economic attraction.” Now competition destroys the economic and social mutual support. People don’t find the high economic return. They want to shrift to other places and find the new economic opportunities. Author thinks that this situation is not a failure but a process for any successful places. And she encourages the combination of zoning for diversity, staunchness of public buildings and competitive diversion in the new diversion. In this chapter, there are examples to support author’s thought and explanation of the ideas.
