Project No. 06442-32-32 - 2 - November 25, 2020
GENERAL
The general contractor for the project was Whiting Turner. The grading contractor was Naton
Engineering. The project grading plans were prepared by Excel Engineering, entitled Precise Grading
Plan For Carlsbad Oaks North Lot 2, Carlsbad, California, Sheets 1 through 10, undated.
Recommendations for the grading were provided in Reference No. 1. Pavement recommendations
were presented in Reference No. 2.
The exhibit used as a base map to present the as-graded geologic information and density test locations
(Figure 1) is a reproducible copy of a compilation of digital information provided by Excel
Engineering. The map depicts the parking lot footprint, and existing and proposed improvements. We
added the approximate locations of the geologic contacts and field density tests performed during
grading and improvement construction.
References to elevations and locations herein are based on as-graded survey information obtained from
grade checkers’ stakes in the field. Geocon Incorporated does not provide surveying services and,
therefore, has no opinion regarding the accuracy of the as-graded elevations or surface geometry with
respect to the approved grading plans or proper surface drainage.
GRADING
Grading consisted of excavating the previously-placed compacted fill and upper portions of the
Santiago formation and Point Loma Formation to generally achieve finish grades. Minor fill soils
derived from on-site excavations were placed and compacted in layers until the design elevations were
attained. Grading generally consisted of cuts and fills of approximately 1 to 3 feet, respectively. Prior
to placing fill or in cut areas, the ground surface was scarified, moisture conditioned, and compacted.
A stormwater basin was removed and replaced with two bioretention basins.
Fill Materials and Placement Procedures
The on-site fill materials generally consisted of clayey sand, silty clay and sandy silt derived from the
Santiago formation and Point Loma formation. The fills were placed in lifts no thicker than would
allow for adequate bonding and compaction. The soil was moisture conditioned as necessary and
mixed during placement.
Field In-Place Density and Laboratory Testing
During the grading operation, compaction procedures were observed and in-place density tests were
performed to evaluate the relative compaction of the fill material. The in-place density tests were
performed in general conformance with ASTM D 6938 (nuclear). Results of the field density tests and
moisture content tests performed during grading and improvement construction are summarized on
Project No. 06442-32-32 - 3 - November 25, 2020
Table I. The approximate locations of the field density tests are shown on the As-Graded Geologic
Map, Figure 1. In general, the in-place density test results indicate that the fill at the locations tested
has a relative compaction of at least 90 percent and near or slightly above optimum moisture content.
Laboratory tests were performed on samples of material used for fill to evaluate moisture-density
relationships, optimum moisture content and maximum dry density, and R-Value characteristics. The
results of the laboratory tests are summarized on Tables II and III.
Finish-Grade Soil Conditions
Observations and laboratory test results indicate that the prevailing soils exposed at parking lot subgrade
have an Expansion Index of less than 90 and classified as having a “medium” expansion potential as
defined by the 2019 California Building Code Section 1803.5.3. However, highly expansive clays were
also observed on-site. The laboratory test results indicate R-values ranging between 3 and 35 with an
average value of 9. A design R-value of 5 was used to compute the flexible pavement section.
SOIL AND GEOLOGIC CONDITIONS
The soil and geologic conditions encountered during grading were found to be generally similar to
those described in the referenced project geotechnical report. The geologic conditions observed during
grading are presented on the As-Graded Geologic Map. No geologic conditions were observed during
grading that precluded the continued development of the property as planned.
IMPROVEMENTS
We have provided testing and observation services during backfill operations for underground
improvements, including electrical, fire service, storm drain and sewer, and during preparation for
sidewalk, curb and gutter, and parking lot subgrade, aggregate base, and asphalt concrete placement
and compaction. Our services were provided on an “on-call” basis between October 13, 2020 and
November 11, 2020.
In-place density tests were performed using a nuclear gauge in accordance with ASTM Test Procedure
D 6938. Laboratory compaction tests were performed on soil samples in accordance with ASTM Test
Procedure D 1557. Laboratory R-value testing was performed in accordance with ASTM D 2844. We
also performed laboratory tests on asphalt concrete samples in accordance with ASTM D 2726
(Hveem density), D 2041 (theoretical maximum density), D 1560 (asphalt concrete stability), D 6307
(asphalt content), and C 136 (sieve analysis for asphalt). The results of the field tests are summarized
on Table I and the results of laboratory tests are summarized in Tables II through VI.
Project No. 06442-32-32 - 4 - November 25, 2020
In-place density test results for underground improvements and curb and gutter and sidewalk subgrade
indicates a dry density of at least 90 percent of the laboratory maximum dry density at the locations
tested. In-place density test results for roadway, parking lot subgrade and aggregate base materials
indicates a dry density of at least 95 percent of the laboratory maximum dry density at the locations
tested. In-place density test results for the asphalt concrete indicates a density of at least 95 percent of the
laboratory Hveem density.
Laboratory tests were performed on representative samples of the asphalt concrete to confirm
Greenbook specifications. Samples AC-1 and AC-3 did not meet the stability specification. However,
the following day, additional samples were collected from the same plant (AC-2 and AC-4) and met
Greenbook specifications. Sample AC-6 was placed as a cap in El Fuerte Street and also did not meet
the stability specification. The field and laboratory test results were provided to Whiting Turner. The
test results for AC-2, AC-4 and AC-5 indicated that the asphalt concrete materials met Greenbook
Specifications. Samples AC-1 and AC-3 were replaced with Samples AC-2 and AC-4. Deviations
from the specifications were bolded in Tables IV through VI.
FOUNDATION OBSERVATIONS
A representative of Geocon Incorporated observed the conventional continuous footings for the
perimeter screen wall. Our observations indicated that the soils encountered in the excavations were
similar to those anticipated in the above-referenced report. In addition, the excavations were observed
to extend to the appropriate bearing strata and to the minimum depth recommended in the geotechnical
report or approved foundation plans.
Specific issues relating to foundation observations, made during each site visit, were indicated on a
copy of our Foundation Observation Report provided to Whiting Turner, the general contractor.
It is the opinion of Geocon Incorporated that from a geotechnical engineering standpoint the wall
foundations have been excavated in substantial conformance with the geotechnical recommendations
presented in the referenced report.
CONCLUSIONS AND RECOMMENDATIONS
1.0 General
1.1 Based on observations and test results, it is the opinion of Geocon Incorporated that the grading
and improvement construction has been performed in substantial conformance with the
recommendations of the referenced project geotechnical report. Soil and geologic conditions
encountered during grading which differ from those anticipated by the project geotechnical
report are not uncommon. Where such conditions required a significant modification to the
recommendations of the project geotechnical reports, they have been described herein.
Project No. 06442-32-32 - 5 - November 25, 2020
1.2 It is our opinion, from a geotechnical engineering standpoint, that the foundations observed
were excavated in substantial conformance with the recommendations of the referenced
report.
2.0 Future Grading and Improvements
2.1 Any additional grading or planned improvements performed at the site should be
accomplished in conjunction with our geotechnical services. Plans for any future
improvements should be reviewed by Geocon Incorporated prior to finalizing. Any
additional trench backfill in excess of 1-foot-thick should be compacted to at least
90 percent relative compaction. This office should be notified at least 48 hours prior to
commencing additional grading or backfill operations.
3.0 Slope Maintenance
3.1 Slopes that are steeper than 3:1 (horizontal:vertical), under conditions which are both
difficult to prevent and predict, may be susceptible to near surface slope instability. The
instability is typically limited to the outer three feet of a portion of the slope and does not
directly impact the improvements on the pad areas above or below the slope. The
occurrence of surficial instability is more prevalent on fill slopes and is usually preceded by
a period of heavy rainfall, excessive irrigation, or the migration of subsurface seepage. The
disturbance and/or loosening of the surficial soils, as might result from root growth, soil
expansion, or excavation for irrigation lines and slope planting, may also be a significant
contributing factor for surficial instability. It is, therefore, recommended that, to the
maximum extent practical: (a) disturbed/loosened surficial soils be either removed or
properly recompacted, (b) irrigation systems be periodically inspected and maintained to
eliminate leaks and excessive irrigation, and (c) surface drains on and adjacent to slopes be
periodically maintained to preclude ponding or erosion. It should be noted that although the
incorporation of the above recommendations should reduce the potential for surficial slope
instability, it will not eliminate the possibility, and, therefore, it may be necessary to rebuild
or repair a portion of the project's slopes in the future.
LIMITATIONS
The conclusions and recommendations contained herein apply only to our work with respect to
grading, improvements, and foundation excavation observations, and represent conditions at the date
of our final observation on November 11, 2020. Changes in the conditions of a property can occur
with the passage of time due to natural processes or the works of man on this or adjacent properties. In
addition, changes in applicable or appropriate standards may occur, resulting from legislation or the
broadening of knowledge in the fields of geotechnical engineering or geology. Accordingly, the
findings of this report may be invalidated wholly or partially by changes outside our control.
Project No. 06442-32-32 - 6 - November 25, 2020
Therefore, this report is subject to review and should not be relied upon after a period of three years.
Any subsequent grading should be done in conjunction with our observation and testing services.
As used herein, the term "observation" implies only that we observed the progress of the work with which
we agreed to be involved. Our services did not include the evaluation or identification of the potential
presence of hazardous or corrosive materials. Our conclusions and opinions as to whether the work
essentially complies with the job specifications are based on our observations, experience and test results.
Due to the inaccuracies inherent in most field and laboratory soil tests, and the necessary assumption that
the relatively small soil sample tested is representative of a significantly larger volume of soil, future tests
of the same soil, location or condition should not be expected to duplicate specific individual test results
of this report. Subsurface conditions, and the accuracy of tests used to measure such conditions, can vary
greatly at any time. We make no warranty, express or implied, except that our services were performed in
accordance with engineering principles generally accepted at this time and location.
We will accept no responsibility for any subsequent changes made to the site by others, by the
uncontrolled action of water, or by the failure of others to properly repair damages caused by the
uncontrolled action of water. It is the responsibility of the Meridian Properties to ensure that the
information and recommendations contained herein are brought to the attention of the architect and
civil engineer for the project, and are incorporated into the plans, and that the necessary steps are taken
to see that the contractor and subcontractors carry out such recommendations in the field.
Recommendations that pertain to the future maintenance and care for the property should be brought
to the attention of the facilities department or entity responsible for future maintenance.
If you have any questions regarding this report, or if we may be of further service, please contact the
undersigned at your convenience.
Very truly yours,
