The actual transition may be gradual. No warranty is provided as <br /> to the continuity of soil strata between borings. Logs represent the soil section observed at the boring location on the date of drilling only. <br /> References to plasticity of cohesive soil are based on qualitative field observations and not on quantitative field or laboratory tests. Qualitative <br /> soil plasticity is noted solely to aid in stratigraphic correlation and is not intended for geotechnical characterization of soils. <br /> BORING LOG LEGEND PLATE <br /> k" K L E I N F E L D E R CANLIS BUILDING /� <br /> SAN JOAQUIN COUNTY A— 1 <br /> PROJECT NO. 24-220191-A00 STOCKTON, CALIFORNIA <br />
