for Lots 1 through 5, Tract 30990, Habitat for Humanity Development, SWC of Pujol Street and
First Street in the City of Temecula, Riverside County, California, Project No. 104629-35, dated
December 11, 2007
In accordance with your request, LGC hiland, Inc. (LGC) has performed geotechnical observation and testing of
utility trenches and retaining walls backfill and street improvements. The utility trenches in this report included
storm drain and joint utility.The sewer and water trench backfill observation and testing were previously reported in
the referenced LGC, 2007 report.
The storm drain trench backfill commenced and was essentially finished in May of 2007. The joint utility trench
backfill commenced in June of 2007 and was essentially finished in July of 2007. Sidewalk grading commenced in
and was essentially finished in September of 2007. The retaining walls backfill commenced and was essentially
finished in September of 2007. Grading of curb and gutter subgrade commenced in June of 2007 and was essentially
finished in September of 2007. Grading of street subgrade commenced in September of 2007 and was essentially
finished in April of 2008. Placement of aggregate base commenced in September of 2007 and was essentially
finished in April of 2008.
SUMMARY OF OBSERVATIONS AND TESTING
Storm Drain and Joint Utility Trench Backtil!
Stone drain and joint utility trenches were backfilled with onsite soils.Backfill materials were watered or air-dried
as necessary to achieve optimum or slightly above optimum moisture conditions prior to and/or during placement,
and then compacted in 18t-inch thick lifts by either a compacting wheel connected to a backhoe or by wheel-rolling
with a front-end loader with a full bucket to a minimum relative compaction of 90 percent ASTM D 1557.The depth
of shading materials (sand)placed above pipes in the trenches varied from approximately 8 to 12 inches and was
jetted prior to placing the backfill materials.
Maximum trench depths were on the order of 2 to 18.5f feet at the time of our geotechnical testing and observation.

Retaining Warr
The proposed retaining walls(with a maximum height of approximately 4 feet) at the subject site were backfilled
with onsite soils. The backfill soils were compacted to a minimum of 90 percent relative compaction in accordance
with ASTM D1557 using either steel-wheeled vibratory rollers or pneumatic-tired rollers.
Street Improvements
Subgrade soils immediately below the curb and gutter, driveway, and street right-of-way were compacted to a
minimum of 90 percent relative compaction in accordance with ASTM D1557 to a minimum depth of 12 inches
using either steel-wheeled vibratory rollers or pneumatic-tired rollers. The aggregate base(AB)was compacted to a
minimum of 95 percent relative compaction ASTM D 1557 using either steel-wheeled vibratory rollers or pneumatic-
fired rollers.
Field Testing
Field density tests were performed using the nuclear gauge test methods(ASTM D2922 and D3017).Test results are
shown on the attached Table II (attached).
The compacted backfills or subgrade areas were tested at the time of placement/preparation to ascertain that the
specified moisture content and relative compaction were achieved. Field density tests were taken at vertical intervals
of approximately I to 2 feet in the trench backfill, where applicable.
When field density tests indicated a relative compaction of less than 90 percent(95 percent for aggregate base),the
approximate limits of the substandard backfill and/or street improvements were established.The substandard area
was reworked, moisture-conditioned and recompacted as necessary or, the substandard materials were removed,
moisture-conditioned and replaced as properly compacted fill, all under the observations of our engineering
technician. In-situ soil density testing is intended to verify the effectiveness of the earthmoving operation in general
and is performed on a spot-check basis;as such,some variations in relative compaction should be expected from the
results documented herein.
Visual classification of earth materials in the field was the basis for determining which maximum density value
summarized in the following Laboratory Testing Section was applicable for a given density test.
Laboratory Testing
The laboratory maximum dry density and optimum moisture content for each major soil type encountered during
backfilling were determined in accordance with test Method ASTM D 1557. Table I below presents the pertinent test
values.

CONCLUSIONS
Based on the results of our part-time observation and selective testing, it is our opinion that the subject utility
trenches and retaining walls backfill has been placed, and the subgrade and aggregate base has been compacted in
accordance and conformance with the recommendations of the geotechnical consultant and the geotechnical
requirements of the City of Temecula.
Limitations
The presence of our field representative at the site was intended to provide the owner with professional advice,
opinions,and recommendations of the contractor's work.Although observations did not reveal obvious deficiencies
or deviations from project 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 include any
supervision or direction of actual work procedures of the contractor, his personnel, or his subcontractors. The
conclusions in this report are based upon test results and observations of the earthwork procedures used and
represent our engineering opinion as to the compliance of the results with the project specifications.

Subject: Geotechnical Addendum Letter for Habitat for Humanity,Lots I and 2 of Parcel Map (PM)34524,
Located on Habitat Way, in the City of Temecula, California
Reference: LGC Inland, Inc., (LGC) 2004, Preliminary Geotechnical Investigation for the Proposed "Habitat
for Humanity" Development, Tract 30990, Pujol Street and First Street in the City of Temecula,
California, Project Number. I04629-10, dated October 20.
2006, Geotechnical Report of Rough Grading for the "Habitat for Humanity"
Development, Tract 30990, Southwest Corner of Pujol Street and First Street in the City of
Temecula, Riverside County, California.
Introduction
LGC Inland, Inc. (LGC) has prepared this addendum letter to present the applicability of previously presented
geotechnical recommendations for the adjacent Tract 30990 to Lots 1 and 2 of Parcel Map (PM) 34524, Located on
Habitat Way, in the City of Temecula, California. The preliminary geotechnical recommendations were
previously presented in the referenced LGC, 2004 report for the adjacent Tract 30990, Lots 1 through 5. LGC also
performed grading observation and testing for this tract and presented the result s and recommendations in the
referenced LGC, 2006 report. The subject site and Tract 30990, Lots 1 through 5 are shown on the attached
Geotechnical Map— Figure 1. During the rough grading of Tract 30990 removal depths generally varied from 3 to
12 feet.
Conclusion and Recommendations
Based on our referenced reports (LGC, 2004 and LGC, 2006) it is our professional opinion that the previously
presented recommendations in the referenced LGC 2004 and LGC, 2006 reports are generally applicable and
valid to the subject site. The anticipated removal depths are shown on the attached Figure 1.
The interpolated subsurface conditions should be checked in the field during construction by a representative of
LGC. Construction observation and testing should also be performed by the geotechnical consultant during
future grading, excavations, backfill of utility trenches, preparation of pavement subgrade and placement of
aggregate base, foundation or retaining wall construction or when an unusual soil condition is encountered at
the site. Grading plans, foundation plans, and final project drawings should be reviewed by this office prior to
construction. Plans should be forwarded to the project geotechnical engineer and/or engineering geologist for
review and comments, as deemed necessary.

Limitations
Our services were performed using the degree of care and skill ordinarily exercised, under similar
circumstances, by reputable engineers and geologists practicing in this or similar localities. No other warranty,
expressed or implied, is made as to the conclusions and professional advice included in this report. The samples
taken and submitted for laboratory testing, the observations made and the in-situ field testing performed are
believed representative of the entire project; however, soil and geologic conditions revealed by excavation may
be different than our preliminary findings. If this occurs, the changed conditions must be evaluated by the
project soils engineer and geologist and design(s)adjusted as required or alternate design(s)recommended.
In addition, changes in applicable or appropriate standards may occur, whether they result from legislation or
the broadening of knowledge. Accordingly, the findings of this report may be invalidated wholly or partially by
changes outside our control.
Closure
We appreciate the opportunity to be of service. Should you have any questions concerning this letter, or should
you require additional information, please do not hesitate to contact this office at your earliest convenience.
Respectfully yours,
