About this map

The Bonnet Carre Floodway dominates this Mississippi River landscape, engineered to divert floodwaters between the river and Lake Pontchartrain. Along the riverbanks, historic settlements like Lucy and Gypsy sit opposite the growing industrial corridors of Norco and Laplace. The map documents a complex landscape of heavy industry and natural hazards, notably marking the site of the Hymelia Crevasse (1912) and the extensive Norco Oil and Gas Field.

Transportation and community infrastructure follow the high ground of the natural levees, with the Illinois Central Gulf RR and Old Hammond Road providing critical links. Local history is preserved in sites like the Montz Cem and numerous parochial institutions including the St Charles High Sch and Accession of Our Lord Sch. The shoreline near Frenier and Frenier Beach illustrates the low-lying marshy transition into the lake at the edge of St John the Baptist Parish.
