City planners are the people who guide the development of cities and towns. They might advise local governments on ways to improve communities, or they might design entirely new communities. In South Florida, for example, city planners are working to improve existing communities. The population of the area is expected to increase from 5.5 million to 7.5 million by 2020. The growth is headed to the west, where there is still open land. But western growth creates a costly need for new roads and is a threat to the ecological system of the Florida Everglades(沼泽地)。 City planners are trying to lure people back into the older, developed eastern section of the region by concentrating growth in that direction and away from the western section.
City planners also plan and develop new communities. These communities, called new cities or new towns, include both places to live and places to work. New cities, such as Brazil's capital Brasilia, a community founded in 1900, can be constructed far from existing cities. Such cities are designed with enough facilities and job opportunities for all residents. Building completely new cities is very costly, however, Brasilia and Canberra, Australia, are two examples of the few new cities that have ever been completed
New towns are different from new cities in that they are built within commuting distance of large cities. They may also be planned communities within a city. New towns provide jobs for many of their residents, but they also rely on neighboring cities for jobs. Two of the first new towns built in the United States were Columbia, Maryland, and Reston, Virginia. At the end of the 20th century an estimated 100 new towns were planned or under construction in the United States.
