summary |
Thirty-eight countries, from all continents except Antarctica, have formal environmental impact review procedures. These impact procedures typically require distinctions between "significant impacts" and "non-significant" impacts. For some issues, such as visual quality, distinguishing the major from the trivial impacts is especially difficult. This paper outlines a theory of visual impacts, shows how the theory can be implemented, and illustrates the theory with three cases histories and a survey of research on the effects of various planning policies. The case histories are examples of statutory and discretionary design review in California and include specifying bay windows on houses, specifying contextual fit, and a before and after study of decisions of a review board. The talk concludes with a discussion of the ranges over which the theory will or will not be applicable and of the opportunities for future cooperative international research. |
