We understand that the proposed residence is a two -story single - family home with framed slab -on -grade garage floors and some concrete slab on grade floors on the lower level living space. The excavations mostly exposed medium stiff to stiff, native, clayey silt. The observed subgrade is adequate for spread foundation support to a maximum allowable bearing pressure of 1,500 psf. Footings should remain outside of a 1 H:1 V plane from vertical cuts. GeoPacific should review the final backfilled configuration and perform density tests as necessary on the backfill No deck footing, patio, or other appurtenant structure subgrades were observed Our work scope pertains to a geotechnical engineer's foundation excavation review only and the conditions existing and exposed at the time of our site visit.
