The approximate exploration locations are shown on Figure 1, the Site and Exploration Plan. Exploration locations were determined by measuring distances from existing site features with a tape relative to an undated Draft Grading and Drainage Plan prepared by PacLand. As such, the exploration locations should be considered accurate to the degree implied by the measurement method. The following sections describe our procedures associated with the exploration. Descriptive logs of the explorations are enclosedin this appendix. Soil Boring Procedures Our exploratory borings were advanced using track- and truck-mounted drill rigs operated by an independent drilling firm working under subcontract to our firm. The borings were completed utilizing hollow-stem auger and mud rotary drilling methods. An experienced geotechnical engineer from our firm continuously observed the borings logged the subsurface conditions encountered, and obtained representative soil samples. All samples were stored in moisture-tight containers and transported to our laboratory for further visual classification and testing. After each boring was completed, the borehole was backfilled with soil cuttings and bentonite clay. Throughout the drilling operation, soil samples were obtained at 2.5- to 5-foot depth intervalsby means of the Standard Penetration Test (ASTM: D-1586). This testing and sampling procedure consists of driving a standard 2-inch outside diameter steel split spoon sampler 18 inches into the soil with a 140-pound hammer free falling 30 inches. The number of blows required to drive the sampler through each 6-inch interval is recorded, and the total number of blows struck during the final 12 inches is recorded as the Standard Penetration Resistance, or blow count"(N value). If a total of 50 blows is struck within any 6-inch interval, the driving is stopped and the blow count is recorded as 50 blows for the actual penetration distance. The resulting Standard Penetration Resistance values indicate the relative density of granular soils and the relative consistency of cohesive soils. Undisturbed samples were obtained by pushing a 3-inch outside diameter, seamless steel Shelbytube into the soil using the hydraulic system on the drill rig in accordance with ASTM:D- 1587. Since the thin wall tube is pushed rather than driven, the sample obtained is considered to be relatively undisturbed. The samples were classified in the field by examining the ends of the tube prior to sealing with plastic caps. The samples were then transported to our laboratory where they were extruded for further classificationand laboratorytesting. The enclosed boring logs describe the vertical sequence of soils and materials encountered in each boring, based primarily upon our field classifications and supported by our subsequent laboratory examination and testing. Where a soil contact was observed to be gradational, our logs indicate the average contact depth. Where a soil type changed between sample intervals, we inferred the contact depth. Our logs also graphically indicate the blow count, sample type, sample number, and approximate depth of each soil sample obtained from the boring, as well as any laboratory tests performed on these soil samples.If any groundwater was encountered in a borehole, the approximate groundwater depth, and date of observation, is DocuSign Envelope ID: 6314EAD5-0BEB-42DD-88C0-371F2EBC8E65 FIELD EXPLORATION PROCEDURES AND LOGS J-1470 Our field exploration program for this project included 43 borings advanced between October September 19, 2002 and October 10, 2002.

Our logs also graphically indicate the blow count, sample type, sample number, and approximate depth of each soil sample obtained from the boring, as well as any laboratory tests performed on these soil samples.If any groundwater was encountered in a borehole, the approximate groundwater depth, and date of observation, is DocuSign Envelope ID: 6314EAD5-0BEB-42DD-88C0-371F2EBC8E65 depicted on the log.Groundwater depth estimates are typically based on the moisture content of soil samples, the wetted portion of the drilling rods, the water level measured in the borehole after the auger has been extracted. The boring logs presented in this appendix are based upon the drilling action,observation of the samples secured,laboratory test results, and field logs. The various types of soils are indicated as well as the depth where the soils or characteristics of the soils changed. It should be noted that these changes may have been gradual, and if the changes occurred between samples intervals, they were inferred. Electric Cone Penetrometer Probes A local exploration company under subcontract to our firm performed three electric cone penetrometer probes for this project on September 26, 2002. The descriptive soil interpretations presented on the cone penetrometer probe logs have been developed by using this classification chart as a guideline.It consists of a steel cone that is hydraulically pushed into the ground at up to 40,000 pounds of pressure. Sensors on the tip of the cone collect data.Standard cone penetrometers collect information to classify soil type by using sensors that measure cone-tip pressure and friction. The detailed interpretive logs of the static cone penetrometer probes accomplished for this study are presented subsequently.
