The average elevation of the city is currently between 1 and 2 feet (0.30 and 0.61 m) below sea level, with some portions of the city as high as 20 feet (6 m) at the base of the river levee in Uptown and others as low as 7 feet (2 m) below sea level in the farthest reaches of Eastern New Orleans.
This is a list of places on land below mean sea level. Places artificially created such as tunnels, mines, basements, and dug holes, or places under water, or existing temporarily as a result of ebbing of sea tide etc., are not included. Places where seawater and rainwater is pumped away are included.
Today, a large portion of New Orleans is at or below local mean sea level and evidence suggests that portions of the city may be dropping in elevation due to subsidence. A 2007 study by Tulane and Xavier University suggested that "51% of the contiguous urbanized portions of Orleans, Jefferson, and St. Bernard parishes lie at or above sea level ...
Gert Town is one of the points of lowest elevation in New Orleans, currently ranging from 0 to −4 meters below sea level. [11] According to geographer Richard Campanella, "vertical migration" patterns, based on topographical elevation, appeared to have a specific effect from 1920 to 2000 in New Orleans. There is no evidence suggesting that ...
A forensic engineering team from the Louisiana State University, using sonar, showed that at one point near the 17th Street Canal breach, the piling extends just 10 feet (3.0 m) below sea level, 7 feet (2.1 m) shallower than the Corps of Engineers had maintained. "The Corps keeps saying the piles were 17 feet, but their own drawings show them ...

French explorers, fur trappers and traders arrived in the area by the 1690s, some making settlements amid the Native American village of thatched huts along the Bayou.By the end of the decade, the French made an encampment called "Port Bayou St. Jean" near the head of the bayou; this would later be known as the Faubourg St. John neighborhood.
New Orleans is at or below sea level, resulting in a high water table in the soil. If a body or coffin is placed in an in-ground tomb in New Orleans, there is risk of it being water-logged or even displaced from the ground.
