2020 Map of Mandeville

About this map

Mandeville and the adjacent settlement of Lewisburg sit along the northern shore of Lake Pontchartrain, where the iconic Lake Pontchartrain Causeway makes landfall. This 2020 survey illustrates the town's grid reaching toward the water, bounded by natural waterways such as Bayou Chinchuba to the west and Bayou Castine to the east. The map provides clear detail for local historians, showing the location of the Mandeville Cem and the complex network of residential streets that have filled in the area between the shore and the inland marshes. Further east, the landscape transitions to the wetlands around Little Bayou Castine and Cane Bayou, leading toward the distinct coastal feature at Green Point.
