To elaborate, the "German Coast" is a description of an area once known as Côte des Allemands along the west bank of the Mississippi River in St. Charles, St. John the Baptist, and St. James parishes. It was never an official area, although that name was used briefly (2 years) as the name of a county that is now part of St John Parish.
