New Orleans at about 0 ft
New Orleans reads sea level at the station, and some neighborhoods famously sit below it — but the bands start at zero and treat the whole first thousand feet the same, so your tested times are exactly the printed ones.
Adjustments come in bands, not curves: everything in the 0–1,000 ft band shares one answer — the recipe exactly as tested. A hill on one side of New Orleans or a valley on the other changes nothing here.
As for the number itself: New Orleans's elevation was checked against the USGS elevation service, starting from the NOAA weather-station inventory (NEW ORLEANS INTL AP). Elevation shifts block to block in any town, but the bands are wide on purpose — a station a few miles out almost never changes the row.

Frequently asked questions
Do I need to adjust canning recipes in New Orleans?
No. At about 0 ft, New Orleans sits inside the 0–1,000 ft band — the elevation range every tested recipe was written for. The minutes printed on the recipe card are your minutes, exactly as they stand.
What pressure does a canner run at in New Orleans?
The tested base settings: 10 lb on a weighted gauge, 11 lb on a dial gauge. No altitude correction applies until a kitchen climbs out of the 0–1,000 ft band, and New Orleans is comfortably inside it.
What if I can somewhere higher — a cabin, a family place in the hills?
Then the bands take over: above the 0–1,000 ft band, a water bath owes extra minutes and pressure settings climb. Look the town up before you pack the jars — the numbers follow the ground, not the kitchen the recipe was written in.
Why do recipes talk about altitude at all if New Orleans needs no changes?
Because water boils cooler as elevation rises, and a cooler bath needs more time to deliver the tested heat. At about 0 ft, the boiling point is close enough to the tested conditions that no correction is needed — that's exactly what the 0–1,000 ft band means.
