About this map

Grand Isle serves as the focal point of this coastal survey, positioned at the edge of the Gulf of Mexico where the waters of Bayou Rigaud meet the marshy barrier landscape. The map captures the residential grid and shorefront streets of the town, including Jefferson Ave, Orleans Ave, and a series of smaller residential ways like Oak Ln and Elm Ln. These streets reflect the compact development necessitated by the island's narrow geography between the open gulf and the Barataria Bay Waterway.

For those researching local heritage, the Grand Isle Cem is a prominent landmark situated within the town's central corridor. The map clearly delineates the boundary between Jefferson Parish and Plaquemines Parish, which extends out into the gulf waters. This 2018 record shows the island's infrastructure and land-use patterns just prior to several major hurricane events that would later reshape this vulnerable coastline.
