ENVIRONMENTAL CONSIDERATIONS IN HIGHWAY PLANNING BY THE CALIFORNIA DEPARTMENT OF TRANSPORTATION

Consideration of environmental factors in the highway planning process of the California Department of Transportation's District Four was measured. In addition, how this consideration is influenced by the District's organizational design, attitudes of planners and engineers, procedures regarding external coordination, and the timing of environmental activities relative to key decision-making points in a planning study were examined. The District Four research was undertaken primarily as an exploratory study to determine if factors that affect the influence of environmental considerations in water resources planning also affect the influence of environmental considerations in highway planning. It was considered more worthwhile to examine in detail a small number of case studies and to develop an in-depth understanding of the highway planning process than to sample an extensive number of highway projects without the benefit of this fundamental understanding. Insights provided during interviews with District Four planners and engineers were used together with the statistical analysis to interpret research results. The principal findings of the research are summarized for each of three dependent variables, namely, factors affecting the influence of environmental considerations in the formulation of alternatives, in the ranking of alternatives, and in the modification of a tentatively selected plan.
