Advanced <br /> GeoEnvironmental, Inc. <br /> 01 November 2011 <br /> AGE-NC Project No. 11-2006 <br /> Ms. Lori Duncan <br /> San Joaquin County Environmental Health Department <br /> 600 East Main Street <br /> Stockton, CA 95202 <br /> Subject: Phase II Site Assessment Work Plan <br /> WARNER PROPERTY <br /> 520 North EI Dorado Street, Stockton, California <br /> Dear Ms. Duncan: <br /> At the request of Dr. P. Babu Sagireddy, Advanced GeoEnvironmental, Inc. (AGE) has <br /> prepared this Phase 11 Site Assessment Work Plan for the property located at 520 North <br /> EI Dorado Street, Stockton, California (the site). The location and plan of the site are <br /> illustrated on Figure 1. <br /> This work plan is prepared as required by the San Joaquin County Environmental Health <br /> Department (SJCEHD) for procurement of a soil boring permit. A Well and Boring Permit <br /> Application, Master File Record(MFR) and associated fees are attached. Upon SJCEHD <br /> approval of the permit package, AGE will schedule field work. AGE will provide SJCEHD <br /> with a minimum of 72-hours prior notice for a grout inspection. <br /> INTRODUCTION <br /> Historical occupancy research of the property identified the site as the former location of <br /> a gasoline station and, prior to the 1950s, a tannery. No records were identified that <br /> indicated any investigation had been performed at the site; either for the gasoline station <br /> or the tannery. Based upon the historical usage of the property, AGE proposes the <br /> following scope of work. <br /> SCOPE OF WORK <br /> AGE proposes to advance a total of six soil borings at the site. Three soil borings will be <br /> advanced along the eastern property boundary to a depth of 20 feet below surface grade <br /> (bsg) and three soil borings will be advanced in the parking lot in the southwestern portion <br /> of the property to a depth of 25 feet bsg. Boring locations may be modified in the field <br /> 837 Shaw Road• Stockton, CA 95215 <br /> Telephone(209)467-1006 • Fax(209)467-1118 <br />
