Page 2 <br /> <br />The site is relatively flat; and we understand that additional raw cut/raw fill is not <br />proposed for the site. <br /> <br />Geotechnical Conditions <br /> <br />Based on the published Based on the published geologic map prepared by the California <br />Division of Mines and Geology (CDMG), the site is located within a broad flat alluvium <br />and colluvium area. <br /> <br />One 50 ft. deep test hole has been drilled for liquefaction study. The approximate location <br />of our test hole is depicted on the attached Site Plan/Geotechnical Map. The geotechnical <br />log of the test hole is included in Appendix B. The laboratory test results are included in <br />Appendix C. <br /> <br />Based on the data of our boring, the near-ground surface soils at the site generally <br />consisted of silty fine sand, damp, and have an expansion index of 14 and a sulfate <br />content of 130 ppm. <br /> <br />Groundwater <br /> <br />Free standing groundwater was encountered at 8 ft. deep in our test hole. <br /> <br />Free standing ground water was not reported to be an issue at the site and in the vicinity. <br /> <br />Deep footings/excavations are not proposed for the site; therefore adverse effects due to <br />groundwater are not anticipated for the proposed development. <br /> <br />Note: it is not anticipated; however, if wet soils are encountered, removal of the wet soils <br />and replacement with drier soils/cement slurry can be performed. In addition, if needed, <br />crushed rock and or geogrids for bridging, etc. can also be used. This will be determined <br />by the geotechnical consultant based on the exposed conditions during the excavations at <br />the site. <br /> <br />Seismicity <br /> <br />The subject site is located in Southern California, which is a major earthquake-prone <br />zone. Therefore, the owner(s) of this property should be aware of the seismic risks <br />associated with being located in this zone. <br /> <br />The Soil Site Class D Default can be used for the soils underlying the subject site. <br /> <br />The Seismic Design Category D can be used for the site. <br /> <br />The following seismic parameters obtained from the computer program https:// <br />seismicmaps.org prepared by SEAOC [Structural Engineers Association Of
