A Trail Across Time: American Environmental Planning From City Beautiful to Sustainability

Problem: It would be useful to identify and connect the major ideas of American environmental planning from the late 19th century up to today, to show its evolution over time and anticipate its potential future direction. Purpose: I aim to tie together the major ideas of American environmental planning, showing how they have evolved, and suggest what additional changes will be required to progress further toward sustainability. Methods: I review the literature, defining five time periods that are useful for understanding and analyzing environmental planning successes and shortcomings. Results and conclusions: Environmental planning has its roots in the physical design of cities and the tension between conserving natural resources for human use and protecting wilderness. In the 1920s, regional environmental planning emerged. Federal environmental impact statements were first required in the 1970s, along with efforts to clean up and prevent pollution. A backlash against government command and control began in the 1980s, leading governments to use incentives to address environmental problems. The current era makes sustainability the goal, tying together the ideas and practices of the previous eras and blending regulation and financial incentives to address national and global environmental problems, such as climate change. To reduce carbon footprints and increase water and energy conservation in the face of significant population growth in the United States will require making environmental planning a political priority, with the goals of curbing sprawling land development, and changing lifestyles and business practices. Takeaway for practice: Environmental planning ideas have been around for the past century and underlie the currently popular concept of planning for sustainability. However, environmental planning has been only modestly effective at influencing business practices and lifestyles. To change this, federal and local governments will have to lead by example, pursuing environmental sustainability as seriously as they pursue economic growth. Research support: None.
