2015 Map of Grand Isle

About this map

Grand Isle occupies a narrow sliver of land between the Gulf of Mexico and Bayou Rigaud, serving as a vital barrier against the open sea. This 2015 survey illustrates a densely developed residential corridor at the island's northeastern end, where a tight grid of streets like Orleans Ave, Loma Linda Ave, and several family-named lanes meet Highway One. The map captures the delicate geography of this coastal community, defined by the parish line between Jefferson Parish and Plaquemines Parish which runs through the surrounding waters. For local historians, the Grand Isle Cem stands as a significant landmark at the heart of the settlement, while the Barataria Bay Waterway to the north indicates the region's continued reliance on maritime navigation and commerce.
