Project No.: 2157-S 1433 Cypress Ave, Santa Ana CITY OF SANTA ANA Planr#qq,png Building Agency Approved FOR PERMIT ISSUANCE Field exploration for the subject site consists of two test borings drilled to depth okf 10 ao1.51 feet aster by means of a hollow stem and hand auger. The approximate test boring locatio �)@f@;indicated on the Site Plan and Boring Location, Plate 2. The exploration was logged by our field PnC.Ionppr and undisturbed ring samples and disturbed SPT samples were obtained for laboratory testing and inspection. Logs of the test borings are enclosed in the Appendix. 5.1 Soil Conditions The subsurface soils disclosed at the test boring consist generally of alternate layers of stiff, silty clay to dense, fine, slightly silty to clean sand to the depth explored of 51 feet. 5.2 Groundwater Groundwater was encountered in one of the test borings at the depth of 14 feet below the existing grade. The historically highest groundwater table at the site is approximately 14 feet deep below grade published by the State of California, Department of Conservation, Division of Mines and Geology, Open -File Report 98-10, Seismic Hazard Evaluation of the Tustin Quadrangle. 6. LABORATORY TESTING Laboratory testing was programmed following a review of the field investigation, and after considering the probable foundation system to be evaluated. Selected soil samples were tested for the following properties: • Field Moisture and Unit Weight (ASTM D-2216) • Shear Resistance (ASTM D-3080) • Consolidation Characteristics (ASTM D-2435) • Grain Size Distribution (ASTM D-422 & ASTM D-1140 • Atterberg Limits (ASTM D-4318) The test results of moisture content and unit weight are tabulated in the Log of Boring, and shearing resistance and consolidation characteristics are plotted on Direct Shear, and Consolidation, respectively, in the Appendix.
