how much fill required over footer?

I have a frost footing around my garage. I am relocating some things to the back wall of garage ( HVAC, pool pump and adding pool heater in future) I want them as low as possible. I plan to level an area, put landscape fabric and then have them put AC condensing units on the plastic bases. Then I will add 2-3 inches of gravel. Is it OK to dig a few inches below the footing so that when I add the gravel it is just covering the top of the footing, or should I have dirt covering the footing completely and if so, how much? I live in Baltimore area and I believe the footing is at least 30in deep.

you will need to keep the dirt high enough so that there is natural drainage away from the footing. it should slope at least 3" in 10' away from this footing other than that digging down is not a problem.
