Repon of Soils Investigation <br />2215 South Standard Ave., Proposed Addition <br />Page 2 of 27 <br />Job No. 40-061 3 <br />I <br />I <br />-'l <br />I <br />I <br />alifomia t9 <br />The possibility of liquefaction occurring during a seismic event within the underlying <br />supporting material is high due to the physical grain-size distribution ofthe deposits, in- <br />place density characteristics, and depth to groundwater. <br />2.0 INTRODUCTION <br />This repon presents the results of our preliminary soils investigation performed to <br />provide planning and design criteria for the proposed development. Contained within are <br />recommendations for site grading and design of structural foundations, selection of floor <br />slab support, and design for structural pavement sections for the proposed building and <br />surrounding area. The investigation for this report included field exploration, laboratory <br />testing, geologic evaluation, and engineering analysis. <br />3.0 SCOPE OF SERVICE <br />The scope of services followed for this investigation included: <br />3.1 Review of available geotechnical, geologic and seismic reports and maps <br />pertinent to the project area. <br />3.2 Geologic hazard evaluation of the site including development of seismic loading <br />parameters. <br />3.3 Subsurface exploration including excavation and field logging of 4 exploratory <br />borings to depths that may be influenced by the proposed structure. <br />3.4 Laboratory testing of representative samples obtained during the field <br />investigation for material properties. <br />l
