Is it just the angle of the pictures, or is that sitting in a
hole? The drainage angles are scary in the photos. =:0

Might be the angle, because it is pretty close to flat. I think there
was something like 2 foot of drop across the entire site when I
started. For reference, it is 40 ft deep x 48 ft wide x 16 ft height.

I ran 4" perf pipe all the way around the footing and off to a nearby
tileline to keep any water that would collect headed away from the
buidling.
