You have no plans to plant anything even remotely edible on our near the
treated area in the future, right?

If I use Roundup (will this endanger bordering hedges and shrubs?),
should I add new topsoil directly on the dead grass, or first till?


I wouldn't leave it all winter without planting something, and that
something may as well be grass. You risk erosion if you leave it bare
and I
can't think of any positive things that will come from a bare lawn. No
matter what you do, you will end up with some weeds. I'm not sure you
need
to go down 8 inches, but its your lawn. I would kill off the grass with
Roundup, correct the grade, cultivate the surface slightly, seed, cover,
and
keep moist. Fall is a good time in most areas, so you can start the
prep in
late summer. Next spring, be sure to apply some pre-emergent herbicide
because there will be weed seeds that will germinate otherwise.
