I read chapter 2 in Health and Community Design: the Impact of the Built Environment on Physical Activity. Chapter two covered urban design periods and concluded that various urban design movements had been mainly motivated by public health. A zoning law case, Euclid v. Ambler Realty, (1926), in the Supreme Court in the USA was discussed. Here the court ignored the rights of the poor. Also neighbourhoods as basic planning units was discussed in this chapter near the end. Planning started to be focused around the automobile which meant that inactivity was being designed in to development. More and more the garden town and the idea that nature equals health drove the intellectuals and the real estate market.
