To many, livability is a suspect term because it defies universal definition. It is a portmanteau for all the positive things that contribute to a desired and achievable lifestyle, all that we hold valuable and worthwhile in our lives. This chapter presents a particular investigation of how a consensus on livability has shaped a city. As with human physiology, good health is the sum total of every aspect of the city: physical, mental, and its other intangible qualities. Urban health encompasses the civic, social, and fiscal well-being of the city, as well as the physical health and well-being of its citizens. Portland is a healthy city in the sense that a balance has been achieved between man and nature. The Pearl District is developed to relatively high densities and supports a mix of jobs, homes for all income levels, as well as services and entertainment. It has become a magnet to those of all ages who value metropolitan lifestyles.
