ELEMENTS OF A GOOD PUBLIC SPACE - A successful public space must include the four main elements of sociability, uses and activities, access and linkages, and comfort and image. A harmonic balance among these four elements will ensure many desired visitors. People utilize parks for different purposes. Some go to parks to walk their dog and others go to parks to play basketball. Therefore, there is no "wrong thing" to put in a park because there will always be something there for somebody. As much as 75% of Americans believe that parks play a large role in combating obesity. It is up to the cities and private donors to provide parks for the community.
