Re: Will grass grow in 2" of soil??
If you have access to a rototiller or have a strong back (or have a shiftless, teenage son you can put to work), mix the fill soil into the sand. That may give you better results. Even if you don't do that it should work, but you may need to water more heavily in that area as it will drain much faster than the rest of the lawn.
The title of your post reminded me of the septic tank at my parent's house, which wasn't buried very deeply (about 2" below the surface). Every summer, the lawn would brown-out there, first. Contrary to Erma Bombeck's assertion, the grass was NOT greener over the septic tank.
