To describe them all in detail would greatly exceed the limits assigned to this paper.....These other times and places, some of which have had incidental mention in the foregoing paragraphs, include: a) When a conflagration rages which scientific city planning might have prevented.
b) When the prevailing winds blow and prove that certain housing and factory districts ought to have been transposed.
c) When ordinary traffic highways are laid out where parkways ought to have been planned.
d) In the selection of sites for future schools.
e) In the layout of mill villages and other industrial housing enterprises.
f) In the activities, good and bad, of real-estate subdividers.
g) In the city's transit system.
h) In the new movement for architectural control.
This social objective in the case of zoning has been admirably stated by Alfred Bettman,as being "always positive and constructive and not merelynega-tive and preventive." And I want to supplement my own earlier definitions by describing intelligent city planning as the application of imagination, skill and justice to the layout and public control of the development of urban areas; and intelligent housing as the application of these same factors to the design and building of structures fit for human habitation. ..... May we not anticipate, for example, a friendly rivalry among the wealthy and public-spirited citizens of each of the forty-eight states in the building of the best-planned town for the motor age, and similar rivalry in all large cities in the development of low-cost garden homes for wage earners? The result would be a stimulus to city planning and housing progress whose benefits in human welfare and happiness would last as long as the world shall endure.
