I looked up a soil classification for an area as "SM" Indianola Sandy Load. The talbes I can find say the bearing capacity is 2000 lbs, but I had another engineer say that the Foundation Analysis and Design book by Bowles states 3000 lbs. Does anyone have a copy they can look up and verify. Don't want to assume the wrong capacity.

At 150 pcf for the concrete, 1' X 2' X 6 X 150pcf = 1800psf, well below the minimum of 2000 psf. There should be no bearing problem here, except if you are adding overturning pressures, much of which, could be dissipated with a wall batter of 1:6 or so.
