"At grade" is a general expression (in architecture and construction) that means above ground, .....i.e. specifically on or at ground level.
Regardless of whether its sloping or flat.
At the most basic level it just means "at ground level"
So the corresponding expressions would be '
Below grade' (underground,...like a parkade or basement) and '
Above grade' (above ground level but not AT ground level,...i.e. higher).
For sloping sites, the convention is that the side of the building where your entrance is, is what is considered 'Grade level'.
Interestingly enough, in Civil engineering, when a road or rail track goes through a mountain that has been tunneled through or blasted through to create the path, then that section of the road is considered 'Below grade',...even though it may be several hundred feet above sea level and any nearby ground.
