During the development of <br /> critical areas at the Granite Tracy Pit site, such as adjacent roads, petroleum pipelines, the <br /> California Aqueduct, etc., a geotechnical engineer should periodically evaluate, for example every <br /> 20 to 25 feet of excavation, whether different or unusual soil condition exist in the slope such as <br /> clean sands, seepage, or perched groundwater. During these visits it may be appropriate that <br /> samples be carved out of the exposed slope and be tested for strength properties. <br /> i <br /> Observations should be summarized in report form and be provided to the necessary agencies <br /> periodically. <br /> We recommend that the portions of the excavated slopes in residual soils alluvial deposits be <br /> protected from erosion as soon as possible after construction. In addition, the flow of surface <br /> water over the slopes should be minimized by constructing channels to divert the flow away from <br /> the slopes. <br /> f F <br /> VI. LIMITATIONS <br /> This completes report the scope of services requested. Conclusions of this report are based on soil <br /> p <br /> conditions derived from five borings drilled for this study and review of borings drilled by Granite <br /> Construction Company. It is possible that soil conditions could change between the points of <br /> exploration. If changes are discovered-during construction', Kleinfelder is available to assist as <br /> needed. This report was prepared in accordance with generally accepted standard of practice <br /> which existed in San Joaquin County at the time the report was written.. No warranty, express or <br /> implied, is made. We note that Granite Construction Company is responsible for the safety of <br /> 20-1 108-1812018RO96. Page 6 of 7 j <br />
