In accordance with the requirements of the City of Santa Ana this soils report has been <br />prepared for the proposed project. <br />Follow is a summary of our findings, conclusions and recommendations. <br /> <br />Site Description and Proposed Development <br />The subject property is located on the easterly side of Hickory St, south of Occidental St, north <br />of Saint Andrew Place, east of Main Street, west of Standard Avenue, south of Edinger Avenue <br />and north of Warner Avenue. <br />A one-story house exists at the site. <br />Based on the Site Plan prepared by the designer, we understand that the proposed ADU will be <br />located in the front yard area. Note: The front yard area where the proposed ADU will be <br />located is currently covered with minor grass and concrete slab. <br />Note to the geotechnical report reviewer: Please see the full-scale plans prepared by the <br />architect/designer/civil engineer which are separately submitted to the City for review, for <br />clarifications/details of the proposed development, as needed. <br />The site is relatively flat; and we understand that minimal raw cut/fill is expected for the site. <br />Geotechincal conditions <br />Based on the published geologic map prepared by the California Division of Mines and Geology <br />(CDMG), the site is located within a broad flat alluvium and colluvium area. <br />One test hole has been drilled using a small diameter auger hand-operated drilling tool down to <br />5 ft deep. The approximate location of our test hole is depicted on the attached Site Plan. The <br />geotechnical log of the test hole is included in Appendix B. <br />Expansion index and atterberg limits test were performed, and the laboratory test results are <br />also included in Appendix B. <br />Based on our filed observation and testing, the near-ground surface soils at the site generally <br />consisted of silty fine sand, damp to moist and have a very low expansion potential. <br />It is noted that the subject site is a previously graded lot which was previously approved by the <br />City of construction of the existing house; and the subject approved lot is also surrounded by <br />previously approved lots where houses exist. Distress to the on-site and off-site existing houses <br />due to deep-seated settlement of the underlying earth materials was not observed and or <br />reported. Thefore, deep-seated settlement is not anticipated to be a problem for the proposed <br />new structures. Therefore, drilling deeper test hole(s) substantial sampling and consolidation <br />1927 & 1929 S <br />Hickory St2/12/2025
