2015 Map of North Islands

About this map

The shifting barrier islands of St. Bernard Parish define this coastal landscape, situated between the open waters of the Gulf of Mexico and the relatively sheltered Chandeleur Sound. This survey captures a highly dynamic environment where thin strips of land are constantly reshaped by tidal forces and seasonal storms. The map serves as a precise record of the shoreline morphology for the northern section of the Chandeleur Islands chain as it existed in the mid-2010s. Lacking any permanent human settlements or infrastructure, the area is characterized by these narrow, fragmented landmasses that provide critical habitats and natural storm protection for the Louisiana coast. The boundary line for St. Bernard Parish is clearly marked as it runs through the waters of the Gulf, illustrating the maritime jurisdictional reach of the parish.
