Project No. D-3885-06 <br />Christ Our Savior Catholic Parish <br />Induced Flooding: The site lies far and/or high enough lrom the coast or any large inland <br />body of water to preclude the hazards of tsunami or seiche waves or inundation from the <br />rupture of an up-gradient reservoir. <br />Induced Subsidence: The unconsolidated alluvial sequence beneath the site is <br />susceptible to some dynamic compression. The degree of differential subsidence across <br />the site is anticipated to be negligible. However, differential settlement may occur due to <br />liquefaction. <br />Field Investigation <br />A. Hollow Stem Auger Borings <br />Field explorations consisted of seven test holes (B- l through B-7) drilled by means of an <br />8" diameter hollow stem auger drill rig and five Cone Penetrometer Tests (CPT-l through <br />CPT-5), at the locations shown on Plot Plan with Boring / CPT Locations Map (Plate B- <br />2). A record of the materials encountered during drilling was made by our field <br />representative and is presented in Appendix B. <br />The lines designating the interface between soil strata on the log of Test Holes represent <br />approximate boundaries. The transition between strata may be gradual. Each test hole was <br />examined and logged in the field. Representative samples were obtained to classi] the <br />soils. In addition, relatively undisturbed samples were obtained for laboratory testing. The <br />relative sampler penetration resistance exhibited by the soils types encountered is <br />tabulated in the blows per foot column of the Log of Test Holes. <br />The attached logs tabulate data based on laboratory classification tests and visual <br />observation by the field geologist at the site. <br />Standard Penetration Resistance <br />Subsurlace conditions are considered to be susceptible to liquefaction during a strong <br />8 <br />I <br />T <br />I <br />I <br />E <br />I <br />T <br />I <br />I <br />T <br />I <br />T <br />I <br />I <br />I <br />I <br />E <br />I <br />E
