Birmingham at about 620 ft
Steel country's ridges look dramatic, but at about 620 ft Birmingham cans in the 0–1,000 ft band with room to spare — from Avondale to Homewood, your tested recipe times apply as written.
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 Birmingham or a valley on the other changes nothing here.
As for the number itself: Birmingham's elevation was checked against the USGS elevation service, starting from the NOAA weather-station inventory (BIRMINGHAM 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 Birmingham?
No. At about 620 ft, Birmingham 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 Birmingham?
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 Birmingham 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 Birmingham needs no changes?
Because water boils cooler as elevation rises, and a cooler bath needs more time to deliver the tested heat. At about 620 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.
