A GIS model for environmentally sensitive areas in Delaware County, Indiana
This study has created a GIS model and comprehensive analysis of environmentally sensitive areas in Delaware County, Indiana. Values were assigned to environmentally sensitive areas for four categories, including woodlands, wetlands, floodplains, and threatened and endangered species. There was an inverse relationship between the size of an area and the environmental sensitivity of the area. These areas occupy twenty-three percent of the total county area. The distribution of these areas is almost equal throughout the county; however, a large portion is located along the banks of the White River and other water bodies. Forty two soil types were identified within environmentally sensitive areas. Poorly drained soils are slightly more represented in the environmentally sensitive areas, and somewhat poorly drained soils are under-represented compared with soils in other drainage classes.
