From the Document: "Situated in the Mississippi Alluvial Plain of the Gulf Coast Prairie Landscape Conservation Cooperative (GCP LCC), the Chitimacha Tribe is one of four federally recognized tribes in Louisiana. [...] For this project, USGS [U.S. Geological Survey] researchers asked how Chitimacha Tribal Lands might be impacted by future sea level rise scenario projections. These models illustrate some flooding within the northernmost boundary of Chitimacha Tribal Lands. [...] This map of the Chitimacha Tribal Lands and surrounding area illustrates the magnitude of potential flooding resulting from future sea level rise at 2 feet, 4 feet, and 6 feet above current sea level."
