Attention: Mr. Tim Stripe
Subject: As-Graded Geotechnical Report of Rough and Fine Grading, Hotel #2 and a
Portion of the Lot 15 Parking Area, Grand Pacific Carlsbad, Carlsbad, California.
i Introduction
In accordance with your request and authorization, Leighton and Associates, Inc. (Leighton) has
I . provided geotechnical observation and testing services during the rough and fine grading
operations for Hotel #2 and a portion of the Lot 15 parking area at the Grand Pacific Carlsbad
resort, boated in Carlsbad, California. This report summarizes our geotechnical observations,
I field and laboratory test results, and the geotechnical conditions encountered during the rough
and fine grading operations of the site.
I The conclusions and recommendations made during the rough grading (Leighton 2006b and
2006d), as well as those presented in the Geotechnical Investigation report (Leighton, 2005a) are
still considered pertinent and applicable to the development of the project and should be followed
I during the post-grading and construction phases of site development. As of the date of this report,
the rough and fine grading operations are essentially complete.
Summary of Rough and Fine Grading Operations
The rough and fine grading operations for the project were performed by Mountain Movers
between October and December 2006. The grading operations were observed and tested by a
representative of Leighton in accordance with the project geotechnical recommendations

I (Appendix A), recommendations made during the course of grading, and the requirements of the
City of Carlsbad.
I The primary grading activity consisted of the overexcavation of the entire Hotel #2 basement
area and the removal of highly expansive clay (considered unsuitable for the support of the Hotel
I building foundation). The removal depth extended at least 10 feet below the subgrade elevation
of the Hotel basement and extended laterally to a minimum -distance of 10 feet beyond the
building limits. The depth of the removals was observed by a representative of Leighton. The
I approximate limit of the removal area is shown on the As-Graded Geotechnical Map for Hotel #2
(Figure 1).
The highly expansive clays were placed at depth in a portion of the Lot 15 parking area (i.e. the
limits presented on Figure 2). As recommended by Leighton (Leighton, 2006d), the clays were
placed at least 5 feet below the parking area subgrade elevation at a moisture content of at least
6-percent over the optimum moisture content. The approximate location of the clay placement
area is presented on Figure 2.
To replace the expansive soils removed from the Hotel #2 basement area, sandy soils (i.e. terrace
deposit) were selectively excavated from above-grade areas elsewhere on the resort site and
I placed in the Hotel #2 basement removal area. Fill placement at the Hotel #2 site also included
the construction of a 1:1 slope along the northern side of the hotel basement. The sandy fill soils
on the Hotel #2 pad, as well as, the fill soils within the upper 5 feet of the parking area were
I compacted to a minimum 90 percent relative compaction at near optimum moisture contents (in
accordance with ASTM Test Method D1557). The very high expansive clays that were buried in
a portion of the Lot 15 parking area were placed at moisture contents of at least 6 percent above
- the optimum moisture content and compacted to a minimum of 85 percent relative compaction.
The results of the field density tests are summarized in Appendix B. The approximate locations
I of the density tests are presented on Figures 1 and 2. Compaction of the fill soils was achieved by
use of heavy-duty construction equipment. Areas of fill in which field density tests indicated
compactions less than the recommended relative compaction or where the soils exhibited
nonuniformity or had field moisture contents less than the minimum moisture content were
reworked. The reworked areas were recompacted and re-tested until the recommended minimum 90
percent relative compaction and minimum moisture content was achieved. Laboratory maximum
dry density tests of representative on-site soils were performed in general accordance with ASTM
Test Method D1557. The test results are presented in Appendix C.
Conclusions
The geotechnical conditions encountered during the rough and fine grading operations for Hotel #2
a portion of the Lot 15 parking area of the proposed Grand Pacific Resort project were generally as
anticipated.. It is our professional opinion that the site is suitable for the intended use provided the
I -2-
Leighton

I recommendations in the project geotechnical reports (Appendix A) and presented herein are
incorporated into the post-grading and construction phases of the project. The following is a
summary of our conclusions concerning the rough and fine grading operations:
I
. Site preparation was geotechnically observed.
Very highly expansive clays were removed to a depth of at least 10 feet below and to a distance
of 10 feet outside the limits of the Hotel #2 basement. Theses soils were placed at least 5 feet
I below the subgrade elevation of the Lot 15 parking area.
The sandy fill soils within 10 feet of the Hotel #2 finish grade surface were moisture I conditioned to -obtain near optimum moisture content and compacted to a minimum 90 percent
relative compaction (in accordance with ASTM Test Method D1557). The expansive clays
were placed at least 6 percent above optimum moisture content and compacted to a minimum I 85 percent relative compaction.
I Recommendations
I Recommendations concerning the post-grading and construction phases of site development for the
project have previously been presented in the project preliminary geotechnical report (Leighton,
2005a). The recommendations presented in the project geotechnical report are still considered
I applicable to the planned development and, should be followed during the future post grading and
construction phases of site development.
I Limitations
1 : The presence of our field representative at the site was intended to provide the owner with
professional advice, opinions, and recommendations based on observations Of the contractor's
work. Although the observations did not reveal obvious deficiencies or deviations from project
I specifications, we do not guarantee the contractor's work, nor do our services relieve the contractor
or his subcontractor's work, nor do our services relieve the contractor or his subcontractors of their
responsibility, if defects are 'subsequently discovered in their work. Our responsibilities did not
I include any supervision or direction of the actual work procedures of the contractor, his personnel,
or subcontractors. The conclusions in this report are based on test results and observations of the
grading and earthwork procedures used and represent our engineering opinion as to the compliance
of the results with the project specifications.
