Page 3 <br /> <br />Groundwater <br /> <br />Free standing groundwater was not encountered in our test hole. <br /> <br />Note: based on the Historically Highest Ground Water Contours and Boring Log Data <br />Locations, Anaheim 7.5-Quadrangle, Plate1.2, Open-file Report 97-08, CDMG, the <br />highest groundwater level at the subject property is about 5-6 ft. deep. <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 <br />California] in conjunction with California’s Office of Statewide Health Planning and <br />Development [OSHPD] ) in accordance with ASCE7-16 can be used for the site. <br /> <br />· Fa = 1.2 <br />· Fv = null* <br /> <br />· Mapped Spectral Accelerations Values: <br /> <br />Ss = 1.331 (for the short period of 0.2 second) <br />S1 = 0.473 (for the 1-second period) <br /> <br />· Maximum Considered Earthquake Spectral Response Accelerations: <br /> <br />SMs = FaSs = 1.597 (for the short period of 0.2 second) <br />SM1 = FvS1 = null* (for the 1-second period)
