WORK PLAN <br /> SUNBORO DEVELOPMENT CORPORATION <br /> SUBSURFACE INVESTIGATION <br /> CORRAL HOLLOW AND BYRON ROADS <br /> TRACY, CALIFORNIA <br /> July, 1988 <br /> INTRODUCTION: <br /> The Sunboro Development Corporation's attorneys, Adleson, Hess, Christensen <br /> and Kelly, Attorney' s at Law, 110 North Third Street, San Jose, California, <br /> 95112, have engaged Terrestrial Technology, Inc. , to perform the following <br /> field work and report writing that will identify and describe the <br /> subsurface soil condition along a line approximately 125 feet south of <br /> Byron Road in Tracy, California (see map, Exhibit A). <br /> This line, or an adjusted alignment, will be established to delineate <br /> between a contaminated soil mass along the Southern Pacific Railroad <br /> right-of-way and a noncontaminated soil mass south of Byron Road, a portion <br /> of which is proposed for subdivision development. Following are <br /> descriptions of the proposed work and reporltto be provided by Terrestrial <br /> Technology, Inc. , to the law firm of Adleson, Hess, Christensen and Kelly. <br /> Task Descriptions: <br /> 1. A surveyed line will be established approximately 125 feet south <br /> of the south right-of-way boundary of Byron Road. The line will <br /> start at Corral Hollow Road and run northwest parallel to Byron Road <br /> for a distance of approximately 2,000 feet to the west . boundary of <br /> the Sunboro Development Company's propelrty. Starting at Corral Hollow <br /> Road points on the above line will be established at approximately <br /> 200 feet intervals. These points will be identified by using <br /> engineering stationing, with offsets, if necessary. <br /> 2. Soil borings to depths of 25 feet will be made at the 200± foot <br /> intervals using a 6 or 8 inch hollow stem auger. The augers will <br /> be steam cleaned after each hole is bred. The driller, with a C-57 <br /> California Contractor's License, will be a person of extensive <br /> experience in making soils borings and soil sampling. The truck <br /> mounted boring machine will be equipped with a split spoon sampler <br /> suitable for taking continuous core sam�les. <br /> 3. Terrestrial Technology, Inc. will be on site when the field work <br /> is proceeding. A licensed California Civil Engineer and a soils <br /> engineer or geologist will be on site to take continuous soil cores <br /> and establish the soil profile of each boring as it is made. Standard <br /> soil identification methods and nomenclature will be used. Soil <br /> profiles will be shown on T.T. I. soil profile forms. <br /> 4. If appropriate, soil samples will be taken from each rbl.©1. <br /> , som ' <br /> of which will be analyzed b a California Certified 1'�boraory for <br /> Y Y 2 <' I 1- <br /> ENV1ROMENTAL HEALTfd <br /> F ERWHT/SERVICES <br />
