This research draws from methodology used by Blanton and Marcus in Yakima County, Washington to measure the floodplain along transportation infrastructure and illustrate the lateral disconnections it creates. By conducting research in my own study area, the results of their research may become more generalizable. It also examines the research done by Harris in Delaware County as a basis for comparison. The study area of Broome County, New York was chosen as much of its transportation infrastructure is built along the Susquehanna and Chenango rivers, the population is similar to that in Yakima County, and there is currently ongoing construction for one of the major highways in the immediate area. In order to create a meaningful comparison, a number of methods will be used including calculation of the total floodplain area, separation of floodplain both inside and outside of transportation boundary lines to determine how much of it is disconnected, statistical analysis to compare between study areas, groundtruthing, and interviews with residents. The results will be displayed using maps, tables, figures, and written analyses. Using these mixed methods, this research aims to build on the work that has already been done and add to the potential national inventory of floodplain fragmentation proposed by Blanton and Marcus.
