FIELD EXPLORATION PROCEDURES AND LOGS
J-1470
Our field exploration program for this project included 43 borings and 3 cone
penetrometer probes advanced between September 19, 2002 and October 10, 2002. 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
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.
