The intent was to identify variation in approaches to scoping in DOTs across the U.S. and to identify the outcomes of scoping on later steps in the environmental review process, through the use of an online survey methodology. In addition, the study asked state DOTs to evaluate their own approaches to scoping. To supplement the national review of scoping practices, four case studies of recent scoping processes conducted by the Minnesota Department of Transportation (Mn/DOT) were completed. The key findings of the study provide insights into the range of approaches used for scoping in state departments of tren-USNational Environmental Policy Act (NEPA)Environmental impact statement (EIS)Environmental reviewState departments of transportation (DOTs)Report
