<br /> <br />ASSOCIATED SOILS ENGINEERING, INC. Project No.: 7160.23 <br />2860 Walnut Avenue, Signal Hill CA 90755 January 23, 2024 <br />Tel: (562) 426 -7990 * Fax: (562) 426 -1842 Page 30 <br />APPENDIX A <br />The following Appendices contain the substantiating data and laboratory test results to complement the <br />engineering evaluations and recommendations contained in the report. <br />Site Exploration <br />On December 1, 2023, field explorations were performed by drilling two (2) test and two (2) percolation <br />borings at the approximate locations indicated on the attached Boring and Percolation Test Location Plan, <br />Plate A. The exploratory borings were drilled by Alroy Drilling Services utilizing a truck mounted CME75, <br />rotary drilling rig equipped with 8-inch diameter continuous flight, hollow-stem rotary augers. The borings <br />extended to depths ranging from 5 feet 1 inches to 26 feet from the existing grades. <br /> <br />Continuous observations of the materials encountered in the borings were recorded in the field. The soils <br />were classified in the field by visual and textural examination and these classifications were supplemented <br />by obtaining bulk soil samples for future examination in the laboratory. Relatively undisturbed samples of <br />soils were extracted in a Modified California barrel sampler lined with 2.416-inch diameter by one-inch high <br />rings and tipped with tapered cutting shoe. All samples were secured in moisture-resistant bags <br />immediately after retrieval from exploratory boring to minimize the loss of field moisture, followed by <br />timely transportation to ASE’s laboratory for ensuing testing. Upon completion of exploration, the borings <br />were backfilled with excavated materials and compacted by tamping. <br /> <br />Description of the soils encountered, depth of samples, field density and moisture content of tested <br />samples, respective laboratory tests performed, as well as Modified California barrel sampler blow counts <br />are presented in the attached Field Logs of Borings / Field Logs of Percolation Boring ("B" Plates). <br /> <br />The subsurface soils descriptions presented in the Field Logs of Boring / Field Logs of Percolation Boring <br />have been interpreted from conditions exposed during the field investigation and/or information inferred <br />from the reviewed geologic literature. As such, it is likely that not all of the subsurface conditions at the Site <br />could be captured or represented. It is therefore essential that the Geotechnical Consultant’s engineer or <br />geologist be on site during grading and foundation construction such that information/recommendations <br />deciphered during preliminary geotechnical investigation phase could be verified and, if necessary, <br />amended as appropriate. <br /> <br />Plate A Boring Location Plan <br />Plates B-1 and B-2 Field Logs of Boring <br />Plates B-P1 and B-P2 Field Logs of Percolation Boring
