RE: Report of Geotechnical Observation and Testing of Rough Grading
Operations - Proposed Palomar Point Development (Buildings A, B and
C) - Located at 1930 Palomar Point Way, in the City of Carlsbad,
California
Dear Mr. Jett:
Pursuant to your request, this firm has provided this geotechnical report to summarize
the observation and testing performed during rough grading operations at the above
referenced project. The geotechnical aspects of the grading were conducted in
accordance with our report titled "Geotechnical Engineering Investigation", dated
November 5, 2001, Project Number 9623-01. Our geotechnical services pertaining to
the grading of the project development are summarized in the subsequent sections of
• this report.
Site Grading
The purpose of the grading operations was for the placement of fill to provide structural
support of the proposed development. All vegetation and demolition debris was stripped
and removed from the fill area prior to the placement of any fill soils. The upper low
density surface soils were removed to competent native soils or bedrock material, the
exposed surface scarified, moisture conditioned and then recompacted to a minimum of
f 90% relative compaction.

Keyways were excavated into competent bedrock material at four locations on the site.
The approximate locations of the keyways are shown on the attached plan.
In addition, foundation areas for Building A were overexcavated in order to permit the
placement of a one foot thick compacted fill blanket beneath foundations. Foundation
areas for Buildings B and C were overexcavated in order to permit the placement of a
three feet thick compacted fill blanket beneath the foundations. In the opinion of this
firm, the native soils are suitable to support the placement of fill material. Grading
extended a minimum of five horizontal feet or to the depth of fill placed whichever is
greater, beyond the edge of the proposed foundations.
Fill soils placed were compacted to a minimum 90% of the laboratory standard in lifts
not in excess of eight inches in thickness. The maximum depth of fill soils placed was
approximately 13 feet. The upper one foot of the building pads were compacted to a
minimum of 95% of the laboratory standard. Conventional earthmoving equipment was
utilized for compaction control. A water truck provided moisture control. Our services
did not include any surveying of excavation bottoms, building corners, or subgrade
elevations during grading operations.
Grading operations were not completed for the slope area adjacent to the north property
line. A crib wall is currently under construction in this area. The slope area will be
graded after construction and backfill of the crib wall is completed.
The proposed street area (Palomar Point Way) was rough graded and left
approximately 1 to 11/2 feet below grade. Grading in this area will be completed at a
later date.

Laboratory/Field Testing
The relative compaction was determined by Sand Cone Method (ASTM: D1556-00) and
by the Drive Tube Method (ASTM: D2937-00). The maximum density of the fill soils was
obtained by the laboratory standard (ASTM: D1557-00) and results are shown on Table
.1. Tests were performed a minimum of every 500 cubic yards placed and every two feet
in depth of fill placed. A summary of the compaction tests of the rough grading
operations are described in Appendix B with locations shown on the accompanying plan.
Additional laboratory tests were performed on representative bulk bag samples of the
near surface soils at the completion of precise grading operations. The tests consisted
of the following:
Expansion index tests in accordance with the Uniform Building Code Standard No.
0 18-2 were performed on remolded samples of the upper soils to determine the
expansive characteristics and to provide any necessary recommendations for
reinforcement of the slabs-on-grade and the foundations. Results of these tests are
provided on Table II in Appendix A.
Soluble sulfate tests in accordance with California Test Method 417 were performed
on representative soils samples to estimate the potential for corrosion of concrete in
contact with the on-site soils. Results are provided on Table Ill in Appendix A.
Foundation Design
All foundations may be designed utilizing the following allowable soil bearing capacities
for an embedded depth of 24 inches, into approved fill materials with the corresponding
widths:.
Allowable Soil Bearing Capacity (psf)
Continuous Isolated
Width (ft) Foundation Foundation
1.5 2000 2500
2.0 2075 2575
4.0 2375 2875

.'
The bearing value may be increased by 500 psf for each additional foot of depth in
excess of the 24 inch minimum depth, up to a maximum of 4,000 psf. A one-third
increase may be used when considering short term loading and seismic forces. Any
foundations located along the property lines or where lateral overexcavations is not
possible may utilize a soil bearing capacity of 1,500 psf. A representative of this firm
shall inspect all foundation excavations prior to pouring concrete. All foundations shall
be reinforced with a minimum of one No. 5 bar, top and bottom.
Slab Design
All concrete slabs-on-grade shall be at least five inches in thickness and placed on
approved subgrade soils compacted to a minimum of 95% relative compaction in the
upper one foot. Reinforcement requirements and an increase in thickness of the slabs-
on-grade may be necessary based upon proposed loading conditions in the structures.
A vapor barrier overlain by a two-inch thick sand layer should be utilized in areas which
would be sensitive to the infiltration of moisture. All concrete slab areas to receive floor
coverings should be moisture tested to meet all manufacturer requirements prior to
placement. All slabs-on-grade shall be reinforced with a minimum of No. 3 bars at 18
inches on-center in both directions positioned in the center of the slab. The upper 18
inches of the subgrade soils shall be moistured to 130% of the optimum moisture
content prior to pouring concrete.
All concrete slabs to be utilized for pavement shall be a minimum of six inches in
thickness and placed on approved subgrade soils.
Corrosion Design Criteria
Representative samples of the surficial soils revealed negligible sulfate concentrations.
Therefore, all concrete in contact with on site soils shall be designed in accordance with
i Table 19A-A-4 of the 1997 Uniform Building Code. Sulfate test results may be found on
the attached Table Ill.
