2018 Map of Mandeville

About this map

Mandeville and the adjacent settlement of Lewisburg occupy the northern shore of Lake Pontchartrain on this 2018 survey. The landscape is defined by the extensive wetland network where numerous waterways, including Bayou Chinchuba, Bayou Castine, and Cane Bayou, drain into the lake. A significant engineering landmark, the Lake Pontchartrain Causeway, originates here, extending southward across the water. The town grid reflects its long-standing development, with historical burial grounds at Mandeville Cem and a dense network of streets like Orleans St and Lafayette St that follow the shoreline. East of the main settlement, the terrain transitions into more preserved marshlands near Green Point and the winding reaches of Little Bayou Castine, illustrating the persistent coastal geography of St. Tammany Parish.
