Underground conduit stub up

[Isaiah]

Is there any place in the code that says the 90 degree elbow has to to be fully below grade before the stub up comes out of the ground?

No, but once it becomes subject to physical damage it must be Sched 80, if using PVC. Exactly when it becomes subject changed here in the last few years. AHJs are wanting Sched 80 PVC 90s now. WAG it comes from Table 300.5 Minimum Cover Requirements.

Only consideration I can think of would be that if part of the curvature or top of the 90EL is exposed the implication might be depth of the burried conduit is inadequate. A 1/2 inch EL with such exposure would definitely be red flag for depth being inadequate, where a 3 or 4 inch EL with similar exposure less likely a depth concern. All depending upon circumstances of installation.
So if your minimum depth (per Table 300.5) can be maintained for the conduit up to the elbow it is possible for a portion of the elbow to be exposed and code compliant.

Don't know if it's applicable here, but I have used two 45s to get around the edge of a footing.
