A long strip footing 3.5 ft wide is to be used to support a masonry bearing wall for a building. The subsurface investigation indicates that the soil at the site is a clay with a unit weight of 110 pcf and a cohesion, c, of 1,200 psf. The angle of internal friction is zero. The clay has a rigidity index of 10. The foundation is constructed 3 ft below the ground surface, and the soil backfill is well compacted. Using a factor of safety of 3, what maximum load should the foundation be designed to support per foot of wall length?
