River to Forty Arpent

The Lower Ninth Ward and Chalmette belong to the same basin. Both districts slope from the river down to the Forty Arpent Zone, where a backbone canal and wetland basins provide stormwater storage during heavy rainfall. The Forty Arpent Zone is also the region’s entry point to the Central Wetlands Unit, a levee-protected urban wetland a mere ten-minute drive from the French Quarter.
