What about for a patio adjoining a house? 1/8" per foot is the

a patio adjoining a house have a 1/4" per foot slope for the first ten
feet away from the house?

No. The slope of a permeable soil surface requires a greater slope.
An impermeable patio surface does not.

....and unless I've missed something, we still don't know what the
surface of the patio. I know the OP said he had concrete in his hips.
