Hazelton Avenue <br /> Stockton, CA 95205 <br /> Via Email: sshih sjgov.orq <br /> Subject: Limited Phase II Site Assessment <br /> Navarra - Blackhawk LLC <br /> 7500, 7590, and 7600 West 11th Street, Tracy, California <br /> Dear Mr. Shih: <br /> AdvancedGeo, Inc. (AGI) has prepared this Limited Phase 11 Site Assessment for the <br /> properties located at 7500, 7590, and 7600 West 11 th Street, Tracy, California (site or <br /> subject property). The scope of work includes advancing ten (10) soil borings for the <br /> collection of soil and grab groundwater samples. <br /> This work plan has been prepared as required by the San Joaquin County Environmental <br /> Health Department (EHD) application for a boring/well permit. The site and surrounding <br /> area are illustrated in Figure 1 . On-site structures and proposed soil boring locations are <br /> illustrated in Figure 2. <br /> 1.0. INTRODUCTION AND BACKGROUND <br /> It is our understanding that a portion of the site was operated at a fueling station from at <br /> least 1930 until 1998. At least eight (8) former underground storage tanks (USTs), three <br /> pump islands and a truck scale were located on the property. Significant investigation of <br /> soil and groundwater were completed between approximately 2000 and 2012 soil or <br /> groundwater have occurred. The site received "closure" for the UST investigation in 2013. <br /> In addition to the former fueling station, the property is serviced by a septic system. <br /> Historically, automobile/truck repairs may have been performed at the site. Industrial <br /> wastes from historical site operations may have been discharged into the septic system. <br /> Based upon the historical site use, AGI recommends an investigation to determine <br /> remaining impacts at the property and verify the previous site closure certification. AGI is <br /> proposing the advancement and sampling of ten (10) shallow soil borings at the site. Each <br /> soil boring will be advanced to depth of approximately 10 to 12 feet bsg.
