About this map

The Mississippi River meanders through this portion of St. John the Baptist Parish, shaping a landscape defined by its proximity to the massive Bonnet Carre Floodway. This engineered flood control system dominates the geography between Montz and Norco, serving as a critical relief valve for the river. The residential expansion of LaPlace is evident in the dense street grids of neighborhoods like Riverland Heights and Carrollwood, while the community of Lucy sits on the opposite bank.

Historically significant landmarks include the Saint John the Baptist Parish East Bank Courthouse Annex and the Providence Rest Haven Cem. To the north, the terrain transitions into the wetlands bordering Lake Pontchartrain, where the small settlement of Frenier remains connected by Old US Hwy 51. The presence of features like the Bonnet Carre Crevasse and Hymelia Crevasse highlights the region's long-standing relationship with river management and alluvial changes.
