1.0 SITE DESCRIPTION
The project site is located at 1044 Carlsbad Village Drive in Carlsbad, California (Figure 1). The
site is bounded by Grand Avenue to the north, an existing Motel 6 facility to the west, Carlsbad
Village Drive to the south and the Interstate 5 offramp to the east. Recent project work summarized
herein consisted of excavation and compaction of shallow subgrade materials for the southeastern
portion of the proposed building pad and the construction of surrounding pavements, flatwork,
utilities, and landscaping.
2.0 FILL PLACEMENT
Existing subgrade materials were overexcavated in general conformance with the project
geotechnical documents and plans, and such that at least 18-inches of recently compacted fill
underlies the building pad and parking lot areas. Overexcavation bottoms were confirmed as firm
and competent by an CTE representative, and then scarified and moisture conditioned prior to
recompaction and placement of compacted fill materials, under observation and testing by a CTE
representative.
Fill materials were moisture conditioned, placed, and compacted in lifts at above optimum moisture
content. Based on CTE’s testing, compaction was performed to a minimum 90 percent relative
density, as determined by ASTM D1557. Grading was performed using standard heavy-duty
construction equipment. Figure 2 presents approximate building pad compaction tests.

3.0 TESTING
Testing was performed to supplement field observations. Testing of compacted fill addressed by this
report was conducted between September 2019 and June 2021 as indicated in the report attachments.
Field-testing of the compacted fill soil was conducted in accordance with ASTM D-6938-17a
(nuclear method). Results of the field-testing indicate that fill materials were compacted to a
minimum relative compaction of 90 percent of the laboratory maximum dry density and at generally
above optimum moisture content as determined by test method ASTM D-1557.
A Site Index Map is provided as Figure 1. Approximate building pad compaction tests are shown on
Figure 2. 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.”
4.0 ADDITIONAL CONSTRUCTION OBSERVATION
All 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
as necessary or required.
5.0 CONCLUSIONS AND RECOMMENDATIONS
CTE concludes that the soil engineering and engineering geologic aspects of the grading covered by
this report are in substantial conformance with the approved geotechnical report (CTE, 2019) and the
grading and improvement plans, 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 report.
Variations may exist and conditions not observed or described in this report may be encountered
during construction.
The geotechnical recommendations herein are intended to minimize the potential for post
construction movement of soils. However, 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 report are encountered, our office should be notified
and additional recommendations, if required, will be provided.
