These are some of the features of the Experimental City, now being planned in all its details at the University of Minnesota. But representatives from business and industry, scholars, and the federal Departments of Housing and Urban Development, Health, Education, and Welfare, and Commerce are not resting with a mere paper program. They are organizing and financing just such a city from scratch. So reports committee member Athelstan Spilhaus of the Franklin Institute in Philadelphia. (Science, Feb. 16, 1968.)
The members of the Minnesota group believe that, in the most basic sense, "the prime pollutant on earth is too many people." If the 200 million people now living in this country were grouped in 800 cities-with a population of 250,000 each, spaced evenly across the country-then the water and air pollution, the traffic congestion, and many of the other ills that plague our cities now would be ended.
The Experimental City will be a densely populated center, surrounded by open land and separated by at least 100 miles from any other major city. Industries that want to operate in the Experimental City will have to abide by the city's extraordinary building regulations and waste-disposal methods. Spilhaus believes they will be willing- because of the tremendous advantages of the city's central waste-processing facilities, smoke sewers, and other underground-disposal facilities. As for people, they will come to the city because it will offer the benefits of urban life without the burdens of conventional cities. The makeup of the population can be balanced by carefully selecting the type of industry invited to join the city, since the industry will influence the work force that comes to live there. The city could he managed, Spilhaus suggests, by a city corporation with professional management.
An Experimental City of this size, the planners calculate, might cost about $4 billion to build. With an average family group of 2.5 people, the 250,000 residents will need 100,000 housing units. These units will cost $20,000 each, and the resulting estimate of $2 billion has been doubled to provide for the substructure this city will have. These costs are not impossibly high.
A strong case can be made for building an entire Experimental City rather than trying out one or more of its elements separately. Everything that happens in a city has an impact on everything else. For example, in a city that is clean and quiet and where factories do not cause pollution, separate industrial and residential zoning is not necessary. When factories, schools, and houses are built in the same neighborhood, there is less need for transportation; when transportation is reduced, air pollution is further diminished. In a city with little pollution, disease is reduced and health-care programs are affected.
The planners of the Experimental City believe that other approaches to ameliorating big-city life are bound to be unsuccessful. Urban renewal in cities already too large, and the building of special communities like Reston, Va. (which can only become dormitories for their big-city neighbors), have not grappled with the main problems. The solution for our polluted cities, then, is ti) get rid of them; to harness modern technology to build a radically different kind of city for the future.
