Dear Mr. Sam:
INTRODUCTION
In accordance with your authorization, we have prepared this Report of Rough Grading presenting the
results of our observation and testing during rough gading of the subject site. All compaction test
results are included in this report in Appendig B Tabie I.
The 20-scale grading plan prepared by HLC civil engineering, of Temecula, California was utilized
during grading and to locate our field density tests and was utilized as a base map for our test locations
presented as Figure 2.

Prolect Description
The subject site had been previously mass graded to establish existing grades. We have reviewed the
report of mass grading prepared by Soil Tech, Inc. (1991) and the preliminary geotechnical �
investigation performed by GEE, (1997). We utilized the recommendations contained in the
referenced report; GEE, (1997). A maximum of 4.0 feet of fill was required to bring the building pad
to design grade and localized areas around the site required fill to achieve finish grade. The project site
is located north of Winchester Road and east of Ynez Road in the City of Temecula, Riverside County,
California. A site map, depicting site boundaries and geographic relationships of the site, is presented
as Figure 1 of this report.
Grading included clearing and � minar cuts, placement and compaction of fill material to
prepare the site. Maximum fill depth was approximately 4 feet along the northeasterly boundary in the
existing drainage ditch within the building pad, including the bacl�illing of the overexcavation for
removal of minor looses soils in the bottom of the ditch.
Site I)escription
The site consists of one generally rectangular-shaped parcel of land. Parcel5 of Parcel Map No. 23335
is bounded to the north by the recently constructed Santa Gertrudis Channel, on the west by recently
graded site then an existing medical center, on the south by Winchester Road, and on the east by
vacant land and a RCWD well site in the southeast corner of the site.
Topographically, the building pad site, prior to the subject grading, consisted of a relatively leve]
graded site at approximately elevation 1060±. Overall relief at the site, prior to the subject gading, was
approximately 3± fe�t.
GRADING PROCEDURES
Site Preparatioa
All though the soils report did not require overexcavation, due to the location of the drainage ditch in
the northe�sterly portion of the site within the building pad, overexcavation was performed to remove
the existing drainage d.itch and loose materials. The area was overexcavaied to expose competent fill
soils. The overeaccavation was performed to a minimum of ten feet wide, centered on the northeasterly
foundation line of the building. The upper one foot of the exposed bottom was ripped, moisture
conditioned and angled dozed to achieve uniform, near optimum moisture. The material was leveled
and tracked in with the Cat D-8 dozer then trackrolled to achieve a minimum compaction of 90%.

Fill Placement
Fill was placed in thin loose lifts approximately 6 to 8 inches thick, brought to near optimum moisture
content and compacted to at least 90% relative compaction (AST'M D1557-78}. Compaction was
achieved by rolling with a Caterpillar track dozer. The maximum laboratory dry density, as
deternuned by ASTM D1557-91, Test Method A(Appendix �, Table �, was utilized as the standard
for field compaction control.
Fill Soils ,
Soils utilized for compacted fill typically consisted of on-site silty sands. Test results are presented in
Appendu �.
C�n�i19 "T�-aeasetions
Rough grading at the site included compaction, and minor temporary fill slope construction. The
subject site was previously mass graded as a fill pad. No transitions from cut to fill e�cist on site. The
entire site as graded consists of fill.
Slope Construction
No permanent slopes were constructed at the site. A temporary slope was constructed near the
perimeter of the site along the northeasterly boundary of the subject site at a maximum slope ratio of
2:1 (horizontal:vertical) to a maximum slope height of approximately 2 feet. There were no cut slopes
on this project.
TESTING PROCEDURES
Field Densitv TesNng
Field density testing was perFormed in accordance with ASTM Test Method D1556-82 (sand-cone
method) and ASTM Test Method D2922-91 (nuclear gauge). Areas failing to meet the minimum
compaction requirements were reworked and retested until the specified degree of compaction was
achieved. The elevations and the results of the field density tests are presented in Appendia C, Results
of Compaction Tests Table I. The approximate location of the tests are shown on the Density Test
Location Maps, Figure 2.
Maximum Densitv Determinations
Maximum Density/Optimum Moisture deternunations were performed in the laboratory on
repre.sentative samples of on-site soils used in the fill operations. The tests were performed in
accordance with ASTM D1557-91, Test Methods A and C. The test res�ilts, which were utilized in
detennining the degree of compaction achieved during fill placement, are presented in Appendia B,
Table I.

RECOMENDA�'IONS
Utilitv 'Y'rench Backfdl
Utility trench bacl�ill should be compacted to a minimum of 90% of the maximum dry density, as
determined by the ASTM 1557 test method. It is our opinion, that utility trench backfill consisting of
on-site or approved sandy soils can best be placed by mechanical compaction to a minimum of 90% of
the maximum dry density. All trench excavations should be conducted in accordance with Cal-OSHA
standards, as a minimum.
Retaanin� Walfls
If restrained walls are to be used, the appropriate active pressures should be derived during the gra�ing
plan review when wall heights and restraint conditions are known.
Walls subject to surcharge loads should be designed for an additional uniform lateral pressure equal to
U3 of the indicated active pressure for unrestrained walls. The wall backfill should be well-drained to
relieve possible hydrostatic pressures on the wall.
Wall footings should be designed in accordance with current Uniform Building Code criteria. Backfill
behind retaining walls should be compacted to a minimum of 90 percent of the maximum dry density.
Surface 1)raina�e
Surface dr aina� e should be directed away frorn foundations of buildings or appurtenant struciures. All
drainage should be directeri toward streets or approved permanent drainage devices. Where
landscaping and planters are proposed adjacent to foundations, subsurface drains should be provided to
prevent ponding or saturation of foundations by landscape water.
Structural Section
Based on R-Value testing of the material at grade at the completion of rough grading, considering a
minimum R-Value of 38 (Appendiz A, Figure 2), we recommend the following st�uctural sections
over 95% compacted subgrade materials.
Light Dutv TT(5.0)
• 0.25 feet Asphaltic Concrete over 0.35 feet of Class 2 aggregate base.
Heaw DutvTi(8.0)
• 0.38 feet Asphaltic Concre�te over 0.75 feet of Class 2 aggregate base.
Concrete Drives and Cross Gutters
• 0.5 feet Portland Cement Concrete over 0.5 feet of Class 2 aggregate base or
0.625 feet of Portland Cemerit Concrete over one foot of 95% compacted
native subgrade, minimum reinforcement should consist of 6X6-10/10 welded
wire mesh, placed at mid heiglrt of the slab,.

Fill Placement
On-site soils are expected to be suitable for use as structural fill with the understanding that the material
has a medium expansion potential. Imported soils, if utilized, should be evaluated by Geotechnical &
Environmental Engineers, Inc. for suitability as structural fill when specific borrow locations are
identified.
Approved fill material should be placed in 6 to 8-inch lifts, brought to near optimum moisture content
and compacted to a minimum of 90% of the maximum laboratory dry density, as determined by the
ASTM 1557 test method. No rocks larger than 6-inches in diameter should be used as fill material.
Rocks larger than 6-inches should either be hauled off-site or crushed to a suitable dimension and used
as fill material.
�'oundation Plan I2eview
Geotechnical & Environmental Engineers, Inc.(GEE) should review the final foundation plans, to
verify conformance with the intentions of these recommendations and those in the referenced reports.
Some additional field or laboratory work may be necessary, at this time.
Construction Monitorin�
Continuous observation and testing, by GEE, Inc. is essential to verify compfiance with
recommendations and to confirm thax the geotechnical conditions encountered are consistent with the
recommendations of this report. Construction monitoring should be conducted by Protech
Environmental & Testing, at the following stages of construction:
• During site grading;
• During construction and bacl�ill of retaining walls;
• During placement and compaction of fill material;
• During excavation of footings for foundations;
• During utility trench bacl�ill operations;
• Durin� subgrade and base compaction for curb, gutter, and paving;
• When any unusual conditions are encountered during gading.
A final geotechnical report, summarizing conditions encountered during improvemerts, accompanied
by an "As-Graded Geotechnical Map", should be submitted upon completion of site improvemerns.
