Erosion is changing the shape of the coastline in southern Louisiana, and 31 place names are set to be removed from the map as a result. "In the course of changing the shoreline, we found a lot of place names that were no longer attached to any features," said Meredith Westington, chief geographer of the National Oceanic and Atmospheric Administration's Office of Coast Survey, which started remapping the area in 2011. The state has developed a $50 billion plan to manage erosion over a 50-year period.
