GENERAL NOTES: 1. Foundation recommendations are based on 3500 lbs./ft.^2 allowable
soil bearing capacity.
2. Foundation recommendations are based on a minimum compressive
strength of 3000 PSI at 28 days.
3. The foundation site must be free of vegetation and debris and
well drained.
4. The foundation should be level within 1/4" overall and within
± 1/8" in any 10 ft. length along the anchor bolt circle.
