testing for verification of potential deep-seated settlement are not considered necessary and not performed for this project. The lowest bearing capacity of 1,500 psf. Is recommended to be used for the proposed new structures. Therefore, direct shear testing is not considered necessary and not performed for this project. For conservative purposes, Type V cement with concrete strength of 4,500 psi is recommended to be used for concrete in contact with the on-site soils. Therefore, sulfate content testing is not considered necessary and not performed for this proposed project. Problems of the underlying soils, if any have been previously properly treated and judged to be adequate for structural support, and approved by the City prior to construction of the existing house. In addition, for conservative purposes, remedial removal/ over-excavation and recompaction of the existing soils underlying the proposed new structure is recommended for this project. Therefore, conventional laboratory tests such as moisture content & in-situ density, grain-size analysis, etc. are not considered necessary and not performed for this project. Groundwater Free standing groundwater was not encountered in our 5 ft deep test hole. Free standing ground water was not reported to be an issue at the site and in the vicinity deep footing/excavation are not proposed for the site; therefore adverse effects due to groundwater are not anticipated for the proposed development. Historic groundwater levels have been recorded approximately 20’ to 25’ below ground surface. Note: it is not anticipated; however, if wet soils are encountered, removal of the wet soil and replacement with drier soils/cement slurry can be performed. In addition, if need crushed rock and or geogrid for bridging, etc. can also be used. This will be determine by the geotechnical consultant based on the exposed conditions during the excavations the site Seismicity The subject site is located in Southern California, which is a major earthquake-pr zone. Therefore, the owner(s) of this property should be aware of the seismic r associated with being located in this zone. The Soil Site Class D Default can be used for the soils underlying the subject site. The Seismic Design Category D can be used for the site. The following seismic parameters obtained from the computer program seismicmaps.org prepared by SEAOC [Structural Engineers Association California] in 1927 & 1929 S Hickory St2/12/2025
