Attention: Mr. Steve Alford
Subject: Geotechnical Report of Rough Grading, Deer Hollow Way
(Stations 10+00 through 44+50), Primrose Street (Stations 10+00
through 26+42), Peach Tree Street (Stations 10+00 through 16+50)
and Pechanga Road Debris Basin, Tract 23065, Temecula Area,
Riverside County, California
This report presents a summary of the observation and testing services provided by
Petra Geotechnical, Inc. (Petra) during rough-grading operations to complete the
construction of the road embankment of Deer Hollow Way (Stations 10+00 through
44+50), Primrose Street (Stations 10+00 through 26+42) and Peach Tree Street
(Stations 10+00 through 16+50) within Tract 23065 located in the Temecula area of
Riverside County, California. In addition to the aforementioned road embankments,
a debris basin was constructed along the south side of Pechanga Road, east of the
intersection with Pala Road. This report also documents the overexcavation and
recompaction of the proposed storm-drain alignment, located adjacent to the east side
of Pal a Road (Stations 149+92 through 158+90) and Pechanga Road (Stations 10+00
through 27+50). This remedial grading was done to facilitate the construction of cast-
in-place pipe. Conclusions and recommendations pertaining to the suitability of the
grading for the proposed construction are provided herein.
Preliminary rough-grading within the golf-course/tract interface was performed within
the subject tract in 1989 and 1990, under the purview of Petra; however, a final rough-
grading report of the interface grading was not prepared at that time. Therefore,

documentation of the previous relevant grading is included with this report. The
balance of rough-grading to complete construction, as well as adjacent slopes and
access streets, was performed during January to July 2002.
REGULATORY COMPLIANCE
Cuts, removal and recompaction of unsuitable low-density surface soils and placement
of compacted fill under the purview of this report have been completed under the
observation of and with selective testing by Petra. The earthwork was perfonned in
accordance with the recommendations presented in previous geotechnical reports by
Petra (see References) and the Grading Code of the County of Riverside.
The completed earthwork has been reviewed and is considered adequate for the
construction now planned. On the basis of our observations, as well as field and
laboratory testing, the recommendations presented in this repOli were prepared in
conformance with generally accepted professional engineering practices and no further
warranty is implied nor made.
SUMMARY OF AS-GRADED SOIL AND GEOLOGIC CONDITIONS
As-Graded Conditions
Remedial grading during the 1989 interface grading generally involved the removal
and recompaction of low-density surficial soils that included alluvial and colluvial
soils subject to hydro collapse or excessive consolidation, as well as near-surface
weathered bedrock materials. As it pertains to the grading addressed in this report, the
removal and recompaction associated with the interface grading was limited to the
northern end of Deer Hollow Way. Remedial grading during the recent phase of rough
grading included Deer Hollow Way, Primrose Street, Peach Tree Street, and the

remedial grading for the debris basin and cast-in-place storm-drain construction along
Pechanga Road and Pala Road. The compacted fills range in depth from approximately
3 to 20 feet. A general description of the soil and bedrock materials underlying the
subject tract is provided below.
. Compacted Engineered Fill (map symbol afc) - The compacted-fill soils placed
in 1989 generally consisted of silty sand and sandy silt with variable amount of
clay. The compacted-fill soils placed in 2002 are comprised of onsite-derived soil
and bedrock materials and generally consist of fine- to coarse-grained sand, silty
sand and clayey sand.
. Alluvium (map symbol Oan - The alluvial deposits left in-place below the
compacted fills in local areas of the tract consist of medium dense to dense, fine-
to coarse-grained sand and silty sand with some gravel.
. Pauba Formation Bedrock (Ops) - The Pauba Formation consists of dense, fine-
to coarse-grained sandstone and silty sandstone with occasional gravel and hard
siltstone beds. Bedding within the Pauba Formation is generally massive with
gradational and indistinct contacts.
SUMMARY OF EARTHWORK
OBSERVATIONS AND DENSITY TESTING
Clearing and Grubbing
At the time of grading, a majority of the tract was covered with a light growth of
grasses and weeds. This light vegetation was removed during overexcavation of
existing grades and mixed with the excavated soils in an acceptable manner (i.e., the
resultant blend contained less than 1 percent organic materials). Heavy vegetation that
existed in local areas, as well as some construction debris, were removed from the site.
Ground Preparation
. Road Embankments -- Deer Hollow Way, Primrose Street and Peach Tree Street
removals were initiated approximately 16 feet outside the right-of-way projecting
outward to the bottom of the removal at a 1: 1 (horizontal:vertical [h:v]). An 8-foot

minimum thickness fill blanket underlies Deer Hollow Way, Primrose Street and
Peach Tree Street. The south-western corner of Primrose Street and Peach Tree
Street have removals of15 to 20 feet deep at a 1: 1 (h:v) projection from the right-
of-way for the slopes which descend to the storm basin.
. Debris Basin -- The removals for the berm and access road for the debris basin on
the south side of Pechanga Road were approximately 3 to 6 feet below original
grade. The bottom of the debris basin and associated cuts are entirely in alluvial
deposits.
. Pala Road/Pechanga Road Storm Drain -- Removals along the east side of Pala
Road and the north side ofPechanga Road were made in order to accommodate the
cast-in-place storm-drain line. The removals varied between 11 and 20 feet in
depth. The bottom of the removals were 30 feet wide with the temporary
excavation slopes cut at approximately 1:1 (h:v).
Prior to placing fill, exposed bottom surfaces in all removal areas were first observed
and approved by our geologist or senior soil teclmician. Following this approval, the
exposed bottom surfaces were scarified to depths of approximately 6 to 8 inches,
watered or air-dried as necessary to achieve a moisture content equal to or slightly
above or below optimum moisture content and then recompacted in-place to a
minimum relative compaction of90 percent.
Fill Placement and Testing
All fill soils were placed in lifts restricted to approximately 6 to 8 inches in maximum
thickness, watered or air-dried as necessary to achieve near-optimum moisture
conditions and then compacted in-place to a minimum relative compaction of 90
percent based on ASTM Test Method D1557. Compaction was achieved by whee1-
rolling with an 824 rubber-tired dozer and loaded scrapers. The maximum vertical
depth of fill placed within the subject site is approximately 20 feet.
Field density and moisture content tests were performed in accordance with nuclear-
gauge test methods ASTM Test Methods D2922 and D3017. Occasional field density

tests were also performed in accordance with the sandcone method ASTM Test
Method D1556. Field density test results are presented on the attached Tables I and
II and approximate test locations are shown on the enclosed Field Density Test
Location/Geotechnical Maps (Plates 1 through 5). Table I presents the results of the
field density tests taken in 1989 and 1990. Table II presents the results of the field
density tests taken in 2002.
Field density tests were taken at vertical intervals of approximately I to 2 feet and the
compacted fills were tested at the time of placement to verify that the specified
moisture content and minimum required relative compaction of90 percent had been
achieved. At least one in-place density test was taken for each 1,000 cubic yards of fill
placed and/or for each 2 feet in vertical height of compacted fill. The actual number
of tests taken per day varied with the project conditions, such as the number of earth-
movers (scrapers) and availability of support equipment. When field density tests
produced results less than the required minimum relative compaction of 90 percent or
if the soils were found to be excessively above or below optimum moisture content,
the approximate limits of the substandard fill were established. The substandard area
was then either removed or reworked in-place.
Visual classification of earth materials in tl1e field was the basis for determining which
maximum dry density value was applicable for a given density test. Single-point
checks were performed to supplement visual classification.
Fill Slopes
No fill slopes were constructed for the road embankments in excess of approximately
3 feet in height.

Cut Slopes
No permanent cut slopes were constructed during grading for the road embankments.
FilI-Over-Cut Slopes
A fill-over-cut slope was constructed within the Pechanga Road debris basin at a
gradient of 4:1 (h:v). This slope attains a maximum height of approximately 14 feet.
LABORATORY TESTING
Maximum Dry Density
Maximum dry density and optimum moisture content for each change in soil type
observed during grading were determined in our laboratory in accordance with ASTM
Test Method D1557. Pertinent test values are summarized in Table III.
RECOMMENDATIONS
Utility Trenches
All utility-trench backfill within the street right-of-ways, utility easements and under
sidewalks, as well as within or in proximity to slopes should be compacted to a
minimum relative density of 90 percent. Where onsite soils are utilized as backfill,
mechanical compaction will be required. Density testing, along with probing, should
be performed by the project soils engineer or his representative, to verify proper
compaction.
For deep trenches with vertical walls, backfill should be placed in approximately 1- to
2-foot thick maximum lifts and then mechanically compacted with a hydra-hammer,
pneumatic tampers or similar equipment. For deep trenches with sloped-walls, backfill

materials should be placed in approximately 8- to 12-inch thick maximum lifts and
then compacted by rolling with a sheepsfoot tamper or similar equipment.
As an alternative for shallow trenches where pipe may be damaged by mechanical
compaction equipment imported clean sand having a sand equivalent value of 30 or
greater may be utilized and jetted or flooded into place. No specific relative
compaction will be required; however, observation, probing and, if deemed necessary,
testing should be performed.
To avoid point-loads and subsequent distress to clay, cement or plastic pipe, imported
sand bedding should be placed at least I foot above all pipe in areas where excavated
trench materials contain significant cobbles. Sand-bedding materials should be
thoroughly jetted prior to placement of backfill.
Pavement Design
It is Petra's understanding that the design of the pavement sections will be provided
by the County of Riverside.
Pavement Construction
As with the pavement design, we understand that observation and testing for the
preparation ofthe pavement sub grade and placement of aggregate base and asphaltic
concrete will be provided by the County of Riverside.
