This report presents guidance on selecting the most appropriate compensatory strategies to mitigate the effects of transportation projects on wetland habitats. Based on a comprehensive review of mitigation practices in the United States, the report discusses the advantages and disadvantages of various approaches and presents guidelines that an agency can use to select mitigation options that will have the greatest chance of success. Case studies are used to illustrate the process used by a number of state departments of transportation (DOTs) to mitigate unavoidable wetland losses. This report will be particularly helpful to transportation planners in state DOTs who have the responsibility of selecting or creating wetland mitigation options on a project-specific or statewide basis. In particular, this report outlines the steps necessary to develop a wetland banking program and provides examples of banking agreements used across the nation.
