Hmm. How much of a step down are you talking about? If I bring this one
down
more than a couple of inches, the outer edge of the slab will be well
below
the ground; I'd need some sort of "curb" surrounding the slab.

What I'm looking at right now would put the top of the slab just below
(1/2
inch or so) the bottom of the door threshold. Sounds like you're saying
that's too close, and that wind-driven rain could still come in under the
door.

I guess it may be a reasonf or concern, but how much rain and snow do you
get? If the water level builds up that much you probably have other
problems to dealw ith. As longs as the slab is pitched, it should not be a
problem. Just like the curb cuts for wheelchar access at the curb. Water
still stays in the street because the sidewalk is still higher than the
street regardless of the sloped access it now has.
