About this map

The Mississippi River defines the landscape of St Charles Parish, where the land is carved into the traditional long-lot survey system characteristic of French colonial influence. This 1930s survey captures the riverfront settlements of Hahnville, Killona, and Goodhope during an era of significant infrastructure expansion. The northern portion of the sheet is dominated by the Bonnet Carre Floodway, a massive engineering project designed to protect downstream communities from river surges.

Inland from the river, the terrain transitions into a dense network of drainage channels such as the Eighty Arpent Canal and Hymel Canal, which supported both agriculture and transportation through the cypress swamps. Local genealogy is anchored by sites like Mt Airy Church and the railroad-oriented communities of Boutte and Paradis. The presence of the Texas and Pacific Railroad and the Southern Pacific Railroad highlights the vital role of rail in connecting these bayou-adjacent settlements to the broader economy.
