Dear Mr. Arriaga:
In accordance with your request, Southern California Soil and Testing, Inc. (SCST) prepared this
report to present the results of field observations and tests performed during the grading for the
planned subdivision.
1. PROJECT DESCRIPTION AND SUMMARY
The project is located north of the intersection of La Costa Avenue and Camino De Las Coches in the
City of Carlsbad, California. Mass grading for the project included the construction of a residential
subdivision, open space area, commercial retail space and office space. This report presents the
earthwork observations and compaction tests performed for office development. In general, the
grading operations consisted of the over-excavation of undocumented fill, alluvium and weathered
rock beneath and the replacement of this or other processed fill material to reach the planned final
pad grade elevations. SCSI performed our services between December 1, 2012 and December 18,
2013. TNT Grading of San Marcos, California performed the grading. TNT Grading provided SCST
with spot elevations, as requested, using their in-field GPS mapping system to assist in determining
Terramar Retail Centers November 13, 2015
La Costa Towne Square —Office Development SCST No. 1211179-70
Carlsbad, California Page 2
the locations and elevations of our field density tests. Since grading, we visited the site in November I 2015 to observe the field conditions
1.1. PRIMARY EQUIPMENT I The primary equipment used for the site mass grading operations included:
John Deere 824 Loader • Water truck
Caterpillar D6 Dozer • Caterpillar 350 Excavator
Caterpillar D8 Dozer • Caterpillar 651 Scraper
. Caterpillar D9 Dozer • Terex 24 Scraper
John Deere 800 Excavator
1.2. CLEARING AND GRUBBING ' Site preparation began with the demolition of the existing improvements and the clearing and
grubbing of the existing vegetation and organic matter at the proposed development area.
The material generated from these operations was exported from the residential site.
1.3. SITE GRADING
In general, the grading operations consisted of the over-excavation of undocumented fill,
alluvium and weathered rock beneath and the replacement of this or other processed fill
material to reach the planned final pad grade elevations. The bottoms of the excavated areas
typically exposed Tertiary-age Del Mar Formation or metavolcanic rock. The grading
contractor scarified, moisture conditioned, and compacted the surface exposed at the bottom
of the excavations.
Fill was placed in 6 to 8-inch lifts, moisture conditioned to near optimum moisture content and
compacted until field density tests indicated a minimum of 90% relative compaction. Figure 1
presents the approximate locations of these tests. All references to optimum moisture and
relative compaction in this report are based on the ASTM D 1557 laboratory test method.
Compaction was achieved by means of a John Deere 824 rubber tire loader and other heavy
construction equipment. This process continued until planned elevations were reached.
Mining excavation occurred at a location on the east end of the site, as shown in Figure 1.
Removals from the excavation were transported off site. Rock was used to backfill the
excavation area. Two foot minus rock was used to backfill the excavation area up to a depth of
approximately 5 feet below finished grade. Six inch minus rock was used for backfill up to a
depth of approximately 18-inches below finished grade. Three inch minus rock was used for ' backfill up to finished grade.
The fill slope, located along the north side of the retaining wall, was built during the
commercial retail space phase of construction as part of field observation and testing services

1.4. SUBDRAINS
Canyon subdrains were installed at the bottom of removals wherever fill depths exceed 10 feet
and where groundwater seepage was observed during grading. Canyon subdrains were
constructed using perforated pipe (SDR 35 or equivalent), surrounded by at least 6 cubic feet
per lineal foot of crushed rock wrapped in filter fabric (Mirafi 140N or equivalent). Figure 1
presents the locations of the installed canyon subdrains. The locations of the canyon
subdrains were surveyed by others.
I 2. AS-BUILT GEOLOGY
An SCSI geologist observed the geologic conditions exposed during grading. The geologic conditions
encountered during grading generally were as anticipated and as presented in the referenced project
I geotechnical report. Figures 1 and 2 present approximate geologic contacts.In our professional
opinion and to the best of our knowledge, no significantly adverse geologic conditions were observed
I and the site appears to be geologically suitable for the proposed construction.
3. SITE IMPROVEMENTS
1 3.1. ANCHOR® WALL BACKFILL
The approximate locations for the Anchor® wall backfill tests are listed on Figures 4 through 7.
The Anchor® wall backfill in-place density tests have been labeled "WB". The contractor
placed manufactured fill material produced by screening and crushing operations on-site for
I the wall backfill. The backfill material was compacted in thin lifts until field density tests
indicated a minimum of 90% relative compaction. Compaction was achieved primarily by
means of a four to six ton riding vibratory roller or hand tamper. The reinforcing grid placement
was also observed.
Backdrains were placed behind each Anchor® wall. The backdrains consisted of 4-inch
1 diameter perforated pipe (SDR 35) surrounded by a minimum of one cubic feet per lineal foot
of crushed rock, which was then wrapped in filter fabric material. As of the date of this report,
I and to our knowledge, these subdrains have not been connected to an approved outlet. It is
recommended that the outlets for the subdrains be kept free of debris and be allowed to freely
I
flow at all times.
Special inspection requirements verified in accordance with ESR-21 13 or Section 4.3 of the ' California Building Code include:
1. Soil conditions were substantially in conformance with those described in the
referenced project geotechnical investigation report.

Carlsbad, California Page 4
The base of the Anchor® wall was founded in a layer of crushed rock that, in turn,
was founded in compacted fill or formational materials. In our opinion, these soils are
suitable for the support of the proposed wall.
The Anchor® wall, including geogrid type, length and placement, was constructed
substantially in accordance with the plans.
The angle of the face of the wall was in substantial conformance with the wall
section on the applicable plans.
The Anchor® wall was constructed with a backdrain at the base of the wall,
immediately behind the block. The backdrains were surrounded by a minimum of one
cubic foot of 3h-inch crushed rock per linear foot. The rock was wrapped with filter
fabric. The backdrain outlets should be connected to storm drains or outlets onto
paved areas, in a timely manner. These outlets should be kept free of debris and be
allowed to freely flow at all times. The outlets have not been tied in to date.
We observed the construction of the Anchor® wall under our purview, and performed
laboratory and field in-situ density /moisture content testing. The results of our tests and
observations are the basis for our opinion that the wall was constructed in substantial
conformance with geotechnical recommendations, the City of Carlsbad Special Inspection
Ordinances concerning Anchor® walls and the California Building Code.
4. FIELD OBSERVATIONS AND LABORATORY TESTS
A representative of SCST performed periodic field observations and density tests during the grading
operations at the locations shown on Figure 1. The density tests were performed according to ASTM
I D 6938 (nuclear gauge) procedures. The results of these tests are shown on Figures 3 through 7. The
accuracy of the in-situ density test locations and elevations is a function of the accuracy of the survey
control provided by others than SCST representatives. Unless otherwise noted, their locations and
I elevations were determined by pacing and hand level methods and should be considered accurate
only to the degree implied by the method used.
I As used herein, the term "observation" implies only that we observed the progress of work we were
involved with, and performed field density tests which, in conjunction with our observations, were the
I
base for our opinion as to whether the work was performed in substantial conformance with the
geotechnical recommendations and the requirements of the applicable agencies.
Maximum dry density determinations were performed on representative samples of the soils used in
the compacted fills according to ASTM D 1557. The results of these tests, presented on Figure 8,
were used in conjunction with the field density tests to determine the degree of relative compaction of
the compacted fill.
Rock corrections were applied to the soil samples having not more than 40 percent by weight retained
on the #4 sieve or not more than 30 percent by weight retained on the %-inch sieve according to
Terramar Retail Centers November 13, 2015
La Costa Towne Square —Office Development SCST No. 1211179-70
Carlsbad, California Page 5
ASTM D 4718. The results of these tests, as presented on Figure 8, were used in conjunction with the
field density tests to determine the degree of relative compaction of the compacted fill.
5. REMAINING WORK
The following operations remain to be completed. It is recommended that field observations and
relative compaction tests be performed during these operations to verify that these operations are
being performed in accordance with job requirements and local grading ordinances.
. Connection of all wall subd rains to approved outlets
The grading contractor sheet graded the pad to the planned final pad grade elevation. We anticipate
additional grading will be required once final development plans are available. The main geotechnical
consideration existing at the site consists of:
. A cut/fill transition across the site
Highly expansive soil
Hard rock that can require blasting or specialized rock breaking techniques to
excavate
SCSI should be contacted to provide specific geotechnical recommendations once the final
development plans are available.
CONCLUSIONS
Based on our field observations and the in-place density test results, it is the opinion of SCSI that the
geotechnical engineering and engineering geology aspects of the grading are in compliance with the
approved referenced geotechnical report, the City of Carlsbad Grading Ordinance, and the
Grading/Improvement Plan Drawing for Project Number C.T. 08-07. Minimum recommendations for
the design of the foundations, as presented in the referenced report(s), remain applicable.
LIMITATIONS
This report covers only the services performed between December 1, 2012 and December 18, 2013.
Our opinions are based on our observations and the relative compaction test results and are limited by
the scope of the work that we agreed to perform.
Our work was performed in accordance with the currently accepted standard of practice and in such a
manner as to provide a reasonable measure of the compliance of the grading and backfill operations
with the project requirements. No warranty, express or implied, is made or intended with respect to the
work that we have performed, and neither the performance of this work nor the submittal of this report
should be construed as relieving the contractor of its responsibility to conform with the project
requirements.
