Mandeville, LA

675 Lafitte St, Mandeville, LA

Last updated 8/27/2026

Mandeville sits on the north shore of Lake Pontchartrain, connected to New Orleans on the lake's southern shore by the Lake Pontchartrain Causeway, which at nearly 24 miles is recognized by Guinness World Records as the longest bridge over a continuous body of water anywhere on Earth. That causeway connection has made Mandeville and the broader north shore area an increasingly popular alternative for New Orleans commuters seeking a quieter, more suburban lakefront community while still maintaining a manageable drive into the city for work, a pattern that's accelerated substantially since Hurricane Katrina. The city's lakefront promenade along Lake Pontchartrain and the Tammany Trace, a paved rail-trail built on a former railroad corridor running through several north shore communities, have given Mandeville an extensive network of walking and biking paths distinct from the more car-dependent development found in parts of the broader New Orleans suburban area. Mandeville's combination of its connection via the world's longest over-water bridge, a growing role as a north shore alternative for New Orleans commuters, and extensive lakefront and rail-trail recreation has made it one of the more distinctively positioned and increasingly popular suburbs anywhere in the greater New Orleans metropolitan area.

Metairie, LA
Metairie sits directly adjacent to New Orleans along the higher, more flood-resistant ridge of land that gives the area its name — "metairie" derives from a French term for a sharecropping arrangement once common on the plantations that occupied the land before suburban development took over in the 20th century. The community saw a substantial population influx after Hurricane Katrina in 2005, as many New Orleans residents whose homes had flooded relocated to Metairie's comparatively higher ground, accelerating growth trends that had already been building in the unincorporated Jefferson Parish suburb for decades. Lakeside Shopping Center, one of the larger regional malls in the greater New Orleans area, anchors a substantial commercial corridor along Veterans Memorial Boulevard that's made Metairie a significant retail destination for the entire metro area, not just its own residents. Metairie's combination of higher, less flood-prone ground relative to much of New Orleans proper, a substantial post-Katrina population influx, and significant regional retail development has made it the largest and most consistently populous suburb anywhere in the greater New Orleans metropolitan area.
Kenner, LA
Kenner is home to Louis Armstrong New Orleans International Airport, the primary commercial airport serving the entire New Orleans metro area, a location that's made the city a natural hub for airport-adjacent hotels, logistics companies, and businesses catering to air travelers passing through the region. The city sits along the Mississippi River and Lake Pontchartrain's southern shore, and its Rivertown historic district has preserved a cluster of small museums and 19th-century buildings along the river, giving Kenner a genuine historic core distinct from its more modern airport-driven commercial identity. Like much of the greater New Orleans area, Kenner sits on low-lying land protected by an extensive levee system, and the city's flood-control and pumping infrastructure has been a subject of continued regional investment and public attention in the decades since Hurricane Katrina exposed serious vulnerabilities across the broader metro area's flood defenses. Kenner's combination of hosting the region's primary international airport, a preserved historic Rivertown district along the Mississippi, and its position within the broader New Orleans area's flood-management system has made it one of the more distinctively positioned suburbs anywhere in the metro area.
Covington, LA
Covington sits on the north shore of Lake Pontchartrain a few miles from Mandeville, and its historic downtown, built around a well-preserved grid of 19th-century buildings, has developed a genuine arts-town identity, with a concentration of galleries, working artist studios, and the St. Tammany Art Association drawing visitors specifically for its creative community. The city has become a haven for writers and musicians over the decades, and Covington's relatively small scale and historic character have made it a popular alternative for New Orleans-area residents seeking a quieter, more walkable small-town setting without leaving the broader metro region entirely. The Tammany Trace rail-trail, the same paved path running through Mandeville, extends through Covington as well, giving the city direct biking and walking access to neighboring north shore communities along a former railroad corridor. Covington's combination of a well-preserved historic downtown, a genuine concentration of working artists and writers, and direct rail-trail connections to neighboring communities has made it one of the more culturally distinctive small towns anywhere on Lake Pontchartrain's north shore.
Slidell, LA
Slidell sits at the eastern end of Lake Pontchartrain's north shore, close to the Mississippi state line, and its position along Interstate 10 and Interstate 12 has made it a significant transportation crossroads for traffic moving between New Orleans, the Gulf Coast, and points further east. The city's Olde Towne Slidell historic district has preserved a walkable cluster of early-20th-century commercial buildings along Erlanger Street, giving the city a small-town downtown core distinct from its newer highway-corridor commercial development. Slidell was significantly impacted by Hurricane Katrina's storm surge in 2005, with substantial flooding across parts of the city, and its recovery and subsequent growth in the years since have made it one of the more closely watched examples of north shore rebuilding and continued suburban expansion in the broader New Orleans metro area. Slidell's combination of its position as a major interstate transportation crossroads, a preserved small-town historic downtown in Olde Towne, and its post-Katrina recovery and growth has made it one of the larger and more strategically positioned suburbs anywhere on Lake Pontchartrain's north shore.
Chalmette, LA
Chalmette is the site of the Battle of New Orleans, fought on January 8, 1815, in which General Andrew Jackson's forces decisively defeated a larger British army in the final major battle of the War of 1812 — a victory that, due to the slow transatlantic communication of the era, actually took place after a peace treaty had already been signed, though word hadn't yet reached either army. Chalmette National Battlefield, part of the Jean Lafitte National Historical Park and Preserve, preserves the battlefield grounds and a national cemetery on the site, giving the small St. Bernard Parish community direct stewardship of one of the most significant battle sites in American military history. The community was devastated by Hurricane Katrina's storm surge in 2005, with St. Bernard Parish suffering some of the most severe and near-total flooding of the entire New Orleans metro area, and Chalmette's subsequent rebuilding has made it a frequently cited case study in Gulf Coast disaster recovery. Chalmette's combination of hosting one of the most historically significant battlefields in American history and its severe Katrina flooding and subsequent rebuilding has made it one of the most historically and recently consequential suburbs anywhere in the greater New Orleans metropolitan area.
