1.0 SITE DESCRIPTION
The subject site, identified as Lot 17 within the Carlsbad Oaks N01th Business Park, is located on
the north side ofWhiptail Loop in Carlsbad, California (Figure 1). The improvement area consists
of a previously graded and currently undeveloped building pad. Initial grading of the subject site
and surrounding lots took place in 2007 under the observation of others (as described in reference
Geocon, 2016), and consisted of placement of an approximately minimum five-foot thick cap of
compacted fill materials over native granitic rock. The site is bounded by developed lots to the west
and south (Lots 18 and 13, respectively), residential homes to the east, and open land to the north.
Recent project work summarized herein consisted of excavation and compaction of subgrade
materials for a proposed building pad, pavement areas, and associated improvement areas, and the
construction of a Mechanically Stabilized Earth (MSE) wall.
2.0 FILL PLACEMENT
Existing subgrade materials were overexcavated in general conformance with the project
geotechnical documents and plans. Previous grading, performed under the observation of others,
generally resulted in a building pad where at least two feet of compacted fill underlies bottoms of
proposed footings. Localized overexcavation to accommodate deeper footings (e.g., loading dock
footings) was performed as part of the recent grading described in this report, along with surficial
grading to achieve finished pad grade. Overexcavation bottoms were confirmed as firm and
competent by a CTE representative, and then scarified and moisture conditioned prior to placement
of new fill materials, under periodic observation by a CTE representative.

Fill materials were moisture conditioned, placed, and compacted in lifts at above optimum moisture
content. Based on the field results, compaction in the tested areas was performed to a minimum 90
percent relative density (95 percent in pavement areas), as determined by ASTM D1557. Grading
was performed using standard heavy-duty construction equipment.
3.0 TESTING
Field-testing, as scheduled by the contractor, was performed to supplement the noted field
observations. Testing of compacted fill addressed by this report was conducted between April, 2017
and July, 2018. Field-testing of the compacted fill soil was conducted in accordance with ASTM D-
6938-08a (nuclear method). Results of the field-testing indicate that fill materials were compacted
to a minimum relative compaction of 90 percent (95 percent in pavement areas) of the laboratory
maximum dry density and at above the optimum moisture content as determined by test method
ASTM D-1557.
Tabulated results of the field compaction testing are provided in the attached Table I. Laboratory
determination of the reference compaction values for the fill materials are provided in Table II,
"Laboratory Test Results." Approximate field compaction test locations for the building pad are
shown on Figure 2.
4.0 ADDITIONAL CONSTRUCTION OBSERVATION
Any additional grading and backfilling should be observed and tested by CTE. However, prior to
any future development of the site, an appropriate updated geotechnical report should be completed.

5 .0 CONCLUSIONS AND RECOMMENDATIONS
CTE concludes that the geotechnical aspects of the grading covered by this report are in general
conformance with the approved geotechnical report (Geocon, 2016) and the grading and
improvement plans (Project No. SDP16-04, Drawing No. 497-3A), additional geotechnical
documents provided during grading, and this final as-graded geotechnical report. Therefore, the
recommendations provided in the referenced report remain suitable for project design and
construction.
6.0 LIMITATIONS
The field evaluation, laboratory testing, and geotechnical analysis presented in this report have been
conducted according to current engineering practice and the standard of care exercised by reputable
geotechnical consultants performing similar tasks in this area. No other warranty, expressed or
implied, is made regarding the conclusions, recommendations and opinions expressed in this rep01i.
Variations may exist and conditions not observed or described herein may be encountered during
construction.
Even with the design and construction precautions provided, some post-construction soil movement
and associated distress should be anticipated. CTE's conclusions and recommendations are based on
an analysis of the observed conditions. If conditions different from those described in this repoti are
encountered, our office should be notified and additional recommendations, if required, will be
provided.
