Class 2 circuit underground beneath parking lot

[nhee2]

Are there any exceptions/provisions that reduce the required cover on underground installation of a Class 2 or Class 3 circuit that is installed beneath a parking lot? I have looked through 725, and as best I can tell - the provisions of Table 300.5 still apply, and any Class 2 or 3, in conduit or direct-buried, needs to be 24" below grade.

Is there another section or exception that I am missing that would reduce this depth?

See section 90.3
Do the rules in Article 725 reference burial depth?

As stated in the original post - i've looked through 725 and did not see anything. But was posting to see if there might be some provision that wasn't obvious to me.

No depth specified. I always go with Chapter 1 requirements though to protect against possible damage.
