2.3 Construction <br /> 2.3.1 Borrow Soil Source <br /> The County will use soil from an existing soil stockpile located at the North County Recycling <br /> Center and Sanitary Landfill (NCRCSL). <br /> Geotechnical investigations on the geologic and hydrogeologic conditions at the NCRCSL <br /> indicate that stockpile soils are predominately fine-grained soils with approximately 30 to 60 <br /> percent passing through a No. 200 sieve. <br /> 2.3.2 Soil Placement <br /> Soil for regrading will be placed on areas designated for repair in lifts of no more than six (6) <br /> inches in loose depth. Prior to compacting, each lift will be moistened(or aerated)to achieve the <br /> proper moisture content. <br /> The County will achieve compaction using standard earthmoving equipment (i.e., compactors, <br /> dozers, etc.) suitable for accomplishing the work described. <br /> 2.3.3 Construction Quality Assurance <br /> County staff will be onsite at all times to provide CQA for this project. County staff duties will <br /> include the inspections of: <br /> • Lift heights <br /> • Moisture content of soil lifts <br /> • Compaction <br /> The County will require the contractor to use portable survey equipment to confirm final grades. <br /> 2.4 Post-Construction Activities <br /> 2.4.1 Final Survey <br /> To document that all areas of the final cover are in compliance with the approved grading plan, <br /> the County will survey the entire Harney Lane Sanitary Landfill property. The survey will be <br /> either aerial or ground as needed to accurately determine final grades. <br /> The topographic survey will also be submitted as the five-year iso-settlement map as described in <br /> Title 27, Section 21090(e)(2), and indicated in the Harney Lane Sanitary Landfill Final <br /> Documentation Report, dated January 1995. <br /> Final Cover Regrading Workplan County of San Joaquin <br /> Harney Lane Sanitary Landfill Public Works Dept. <br /> April 25,2002 2-2 Solid Waste Division <br />
