Jefferson Parish

Jefferson Parish is an administrative district in Louisiana that spreads along both banks of the Mississippi River between Lake Pontchartrain and the Gulf of Mexico. The area includes several cities and towns, with neighborhoods ranging from urban centers to suburban developments and large expanses of wetlands.

The district was created by the Louisiana Legislature in February 1825 and named after President Thomas Jefferson, with Gretna serving as the seat. Development took place mainly along the Mississippi and later toward Lake Pontchartrain, shaping the spread of the area today.

The parish population of 440,781 residents represents a mix of communities across cities like Metairie, Kenner, and Gretna, each maintaining local traditions.

The area is connected by several main highways and bridges crossing the Mississippi River, making it easier to move between different communities. Many parts are close to water, so visitors should be prepared for flooding during heavy rain periods and plan accordingly.

The area has an unusual balance between land and water, with water covering more of the total territory than land does. This characteristic has influenced how communities developed, with many settlements built along raised natural levees and man-made embankments.
