For this type of construction, we estimate that typical wall loads <br />wi'I be on the order of 3 to 4 kips per Iineai foot and the column loads less <br />than 50 kips. <br />Discussion_ <br />The borings indicate the surficial soils are fairly weak and variable. The <br />fill and soil classified as may be fill are quite loose. in our opinion, these <br />soils should not be relied upon for foundation support. <br />The underlying alluvial <br />soils generally are quite loose or have a medium con- <br />sistency. While these soils are fairly weak, in our opinion they will provide <br />adequate support for spread footing foundations. Since the cohesive and <br />granular soils show differen'. settlement characteristics, we recommend that <br />the foundations be supported on controlled fill rather than be extended to <br />the underlying natural soil. This will allow placement of all footings at <br />the normal footing elevation and will also minimize differential settlement. <br />Foundation Recommendations <br />It is our opinion that the proposed structure can be supported on spread <br />footing foundations. We recommend excavating all existing fill and topsoil <br />from the footing arras. We then recommendlacin <br />P g a controlled fill to the <br />normal footing elevation. The excavation and compacted fill should extend <br />soK exPLoRc-*Cn <br />CC...►w <br />
