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 report 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 and 1990 interface grading generally involved the
removal and recompaction of low-density surficial soils that included alluvial and
colluvial soils subject to hydrocollapse or excessive consolidation, as well as near -
surface weathered bedrock materials. Remedial grading of the site at that time
consisted of removal and recompaction of all low-density surficial material, removal
of haul roads and loose end -dumped fill piles. Remedial grading during the recent
phase of rough grading included similar removals plus surficial overexcavation and
recompaction, on the order of up to 2 to 4 feet. Remedial grading also included
overexcavation of the cut portions of cut/fill transition lots. The compacted fills range
in depth from approximately 3 to 58 feet. A lot -by -lot summary of the compacted -fill
depths and a summary of soil conditions is presented in the attached Table I. 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 through 1998 generally consist of silty sand and sandy silt with variable
clay. The compacted -fill soils placed in 2002 are also comprised of onsite -derived

soil and bedrock materials and generally consist of fine- to coarse-grained sand,
silty sand and clayey sand.
Pauba Formation Bedrock (Ons) — The Pauba Formation consists of dense, fine-
grained and well -graded sandstones, clayey sandstone and clay beds with
occasional gravel and cobble beds. A cross -bedded, well -graded sand unit is
contained within the Pauba Formation.
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 to
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
1988 - 1990 - During the interface grading perforated in 1989 and 1990, unsuitable
soils were removed and replaced with compacted fill. Removal of unsuitable soils
was performed to facilitate future grading by eliminating the need to encroach into
the completed golf -course fairways during final rough grading of the subject tract.
Removal of unsuitable soils extended laterally into the subject tract at a I:1
(horizontal: vertical [h:vl) projection from the proposed toe -of -slopes to the bottom
of the overexcavation in order to provide sufficient lateral support for the
embankment fills. As a result of the removals, the alluvial soils anticipated to be
subject to hydrocollapse or excessive consolidation that existed within the broader
valley areas were removed. In areas to receive compacted fill, all deposits of
existing low-density surficial soils (slopewash and alluvium) were removed to
competent bedrock. In general, removal of unsuitable surficial materials varied
from approximately 3 to 10 feet below the original ground surface. All removals
were also extended into adjacent street areas to receive compacted fill.
• 2002 -Prior to placing structural fill, existing low-density surficial soils were first
removed to competent unweathered bedrock, or previously placed compacted -fill

materials. Removals throughout the lots varied from approximately 3 to 8 feet.
Previously compacted -fill materials exposed in removal areas exhibited an in-place
minimum relative compaction of 90 percent.
'
Prior to placing fill, exposed bottom surfaces in all removal areas were first observed
'
and approved by our project geologist or senior soil technician. 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 optimum moisture content and then recompacted in-place to a minimum
'
relative compaction of 90 percent or 95 percent where fill thickness exceeds 50 feet.

Lot Overexcavations
To mitigate distress to residential structures related to the potential adverse effects of
excessive differential settlement, the cut portion of cut/fill transition lots were
overexcavated to a minimum depth of 3 feet below finish grade and replaced with
compacted fill. Cut lots on which expansive clay beds were exposed at grade were
also overexcavated on the order of 8 feet to minimize the effect of expansive soils.
Canyon Subdrains
Canyon subdrains were placed in areas where the depth of structural fill exceeded 15
feet. Subdrains consisted of 6- to 8 -inch diameter PVC pipe with perforations placed
down. The pipe was surrounded by 0.75 inch gravel and wrapped in filter fabric
(Mirafi 140 or equivalent). Subdrain locations are provided on Plates 1 and 2.
The subdrains are outletted to the golf course at the toe -of -slope near Lots 57, 83 and
109.

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 wheel -
rolling with an 824 rubber -tired dozer and loaded scrapers. The maximum vertical
depth of fill placed within the subject lots is approximately 58 feet on Lot 92.
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 for 1989 and 2002 are presented on the
attached Tables Il and 111, respectively, and approximate test locations are shown on
the enclosed Geotechnical Map with Density Test Locations (Plates 1 and 2).
Field density tests were taken at vertical intervals of approximately 1 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 of 90 percent had been
achieved or 95 percent relative compaction where fill thickness exceeds 50 feet. 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 earthmovers
(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 the 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
All fill slopes were constructed at a maximum ratio of 2:1 (h:v) and to a maximum
height of approximately 40 feet. All fill slopes were overfilled an average of 4 to 5
feet during construction and then trimmed back to the compacted core. The fill slopes
are considered grossly and surficially stable to the heights and inclinations at which
they are constructed.
Fill keys were constructed along the toe -of -slope at the tract/golf-course interface
within Lots 64 through 66 and 74 through 77. The keys were 15 to 25 feet wide and
were 5 feet deep.
Cut Slopes
All cut slopes expose competent Pauba Formation bedrock and were constructed at a
maximum ration of 2:1 (h:v) and to a maximum height of 22 feet (Lot 73). The cut
slopes are considered grossly and surficially stable to the heights and inclinations at
which they are constructed.
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 for each phase of grading (1989 and 2002)
are summarized in Appendix A.

at or near finish grade within the subject lots. These tests were performed in
accordance with California Test Method No. 417. Test results are summarized in
Appendix A.
Chloride, Resistivity and pH Analyses
Water-soluble chloride concentration, resistivity and pH were determined for selected
samples in accordance with California Test Method Nos. 422 (chloride) and 643
(resistivity and pH). The results of these analyses are summarized in Appendix A.

Allowable Soil -Bearing Capacities
ities
An allowable soil -bearing capacity of 1,500 pounds per square foot (psf) may be used
for 24 -inch square pad footings and 12 -inch wide continuous footings founded at a
minimum depth of 12 inches below the lowest adjacent final grade. This value may
be increased by 20 percent for each additional foot of width or depth, to a maximum
value of 2,500 psf. Recommended allowable soil -bearing values include both dead
and live loads and may be increased by one-third when designing for short -duration
wind and seismic forces.
Anticipated Settlement
Based on the general settlement characteristics of the compacted fill soils, as well as
the anticipated loading, it has been estimated that the maximum total settlement of
building footings will be less than approximately 0.75 inch. Maximum differential
settlement over a horizontal distance of 30 feet is expected to be about one-half the
total settlement. The maximum anticipated differential settlement of 0.38 inch in 30
feet may be expressed as an angular distortion of 1:960.
Lateral Resistance
A passive earth pressure of 250 psf per foot of depth to a maximum value of 2,500 psf
may be used to determine lateral -bearing resistance for building footings. Where
structures such as masonry block walls and retaining walls are planned on or near
descending slopes, the passive earth pressure should be reduced to 150 psf per foot of
depth to a maximum value of 1,500 psf. In addition a coefficient of friction of 0.40
times the dead -load forces may also be used between concrete and the supporting soils
to determine lateral -sliding resistance. An increase of one-third of the above values
may also be used when designing for short -duration wind and seismic forces.

The above values are based on footings placed directly against compacted fill. In the
case where footing sides are formed, all backfill against the footings should be
compacted to a minimum of 90 percent of maximum dry density. For foundations
founded in cut areas of Pauba Formation, the coefficient of friction should be 0.30.
Footing Observations
All footing trenches should be observed by a representative of Petra to verify that they
have been excavated into competent -bearing soils and to the minimum embedments
recommended herein. The foundation excavations should be observed prior to the
placement of forms, reinforcement or concrete. The excavations should be trimmed
neat, level and square. All loose, sloughed or moisture -softened soil and any
construction debris should be removed prior to placing concrete.
Excavated soils derived from footing and utility -trench excavations should not be
placed in slab -on -ground areas unless the soils are compacted to a minimum of 90
percent of maximum dry density.
Expansive Soil Considerations
Results of laboratory tests indicate onsite soil and bedrock materials exhibit VERY
LOW, LOW and MEDIUM expansion potentials as classified in accordance with
1997 Uniform Building Code (UBC) Table 18 -I -B. A lot -by -lot breakdown for the
different levels of expansion is provided below.
• Very Low Expansion Potential - Lots 39 through 41, 44 through 61, 67, 68, 74

Design and construction details for the various levels of expansion potential are
provided in the following sections.
Very Low Expansion Potential (Expansion Index of 20 or less)
The following recommendations pertain to as -graded lots where the foundation soils
exhibit a VERY LOW expansion potential as classified in accordance with 1997 UBC
Table 18 -I -B. For soils exhibiting expansion indices of less than 20, the design of
slab -on -ground foundations is exempt from the procedures outlined in 1997 UBC
Section 1815. Based on this soil condition, it is recommended that footings and floors
be constructed and reinforced in accordance with the following minimum criteria.
However, additional slab thickness, footing sizes and/or reinforcement should be
provided as required by the project architect or structural engineer.
• Footines
Exterior continuous footings may be founded at the minimum depths indicated
in 1997 UBC Table 18-1-C (i.e., 12 -inch minimum depth for one-story and I8 -
inch minimum depth for two-story construction). Interior continuous footings
for both one- and two-story construction may be founded at a minimum depth
of 12 inches below the lowest adjacent grade. All continuous footings should
have a minimum width of 12 and 15 inches, for one- and two-story buildings,
respectively and should be reinforced with two No. 4 bars, one top and one
bottom.
Exterior pad footings intended for the support of roof overhangs, such as
second -story decks, patio covers and similar construction, should be a minimum
of 24 inches square and founded at a minimum depth of 18 inches below the
lowest adjacent final grade. No special reinforcement of the pad footings will
be required.
• Floor Slabs
- Living -area concrete -floor slabs should be 4 inches thick and reinforced with
either 6 -inch by 6 -inch, No. 6 by No. 6 welded -wire fabric (6x6-W2.9xW2.9
WWF) or with No.3 bars spaced a maximum of 24 inches on center, both ways.

' All slab reinforcement should be supported on concrete chairs or bricks to
ensure the desired placement near mid -depth.
Living -area concrete -floor slabs should be underlain with a moisture -vapor
barrier consisting of a polyvinyl chloride membrane, such as 6 -mil Visqueen or
equivalent. All laps within the membrane should be sealed and at least 2 inches
' of clean sand be placed over the membrane to promote uniform curing of the
concrete.
' Garage -floor slabs should be 4 inches thick and should be reinforced in a similar
manner as living -area floor slabs. Garage -floor slabs should also be placed
separately from adjacent wall footings with a positive separation maintained
1 with 3/8 -inch minimum, felt expansion joint materials and quartered with
weakened -plane joints. A 12 -inch wide grade beam founded at the same depth
as adjacent footings should be provided across garage entrances. The grade
' beam should be reinforced with a minimum of two No. 4 bars, one top and one
bottom.
' - Prior to placing concrete, the subgrade soils below all concrete slab -on -ground
should be prewatered to promote uniform curing of the concrete and minimize
' the development of shrinkage cracks.
' Low Expansion Potential (Expansion Index of 21 to 50)
The following recommendations pertain to as -graded lots where the foundation soils
' exhibit a LOW expansion potential as classified in accordance with 1997 UBC
Table 18-1-B. The 1997 UBC specifies that slab -on -ground foundations (floor slabs)
resting on soils with an expansion index greater than 20 require special design
considerations in accordance with 1997 UBC Section 1815. The design procedures
' outlined in 1997 UBC Section 1815 are based on the thickness and plasticity index of
each different soil type existing within the upper 15 feet of the building site. For final
design purposes we have assumed an effective plasticity index of 12 in accordance
with 1997 UBC Section 1815.4.2.

The design and construction recommendations that follow are based on the above soil
conditions and may be considered for minimizing the effects of slightly (LOW)
expansive soils. These recommendations have been based on the previous experience
of Petra on projects with similar soil conditions. Although construction performed in
accordance with these recommendations has been found to minimize post -construction
movement and/or cracking, they generally do not positively mitigate all potential
effects of expansive soil action. The owner, architect, design civil engineer, structural
engineer and contractors must be made aware of the expansive -soil conditions which
exist at the site. Furthermore, it is recommended that additional slab thicknesses,
footing sizes and/or reinforcement more stringent than recommended below be
provided as required or specified by the project architect or structural engineer.
• Footines
- Exterior continuous footings may be founded at the minimum depths indicated
in 1997 UBC Table 18 -I -C (i.e., 12 -inch minimum depth for one-story and 18 -
inch minimum depth for two-story construction). Interior continuous footings
for both one- and two-story construction may be founded at a minimum depth
of 12 inches below the lowest adjacent grade. All continuous footings should
have a minimum width of 12 and 15 inches, for one- and two-story buildings,
respectively and should be reinforced with two No. 4 bars, one top and one
bottom.
- Exterior pad footings intended for the support of roof overhangs, such as
second -story decks, patio covers and similar construction, should be a minimum
of 24 inches square and founded at a minimum depth of 18 inches below the
lowest adjacent final grade. The pad footings should be reinforced with No. 4
bars spaced a maximum of 18 inches on centers, both ways, near the bottom -
third of the footings.
• Floor Slabs
- The project architect or structural engineer should evaluate minimum floor -slab
thickness and reinforcement in accordance with 1997 UBC Section 1815 based
on an effective plasticity index of 12. Unless a more stringent design is
recommended by the architect or the structural engineer, we recommend a

' beam founded at the same depth as adjacent footings should be provided across
garage entrances. The grade beam should be reinforced with a minimum of two

Prior to placing concrete, the subgrade soils below all living -area and garage -
floor slabs should be pre -watered to achieve a moisture content that is at least
equal to or slightly greater than optimum -moisture content. This moisture
content should penetrate to a minimum depth of 12 inches into the subgrade
soils.
Medium Expansion Potential (Expansion Index of 51 to 901
The following recommendations pertain to as -graded lots which exhibit a MEDIUM
expansion potential as classified in accordance with 1997 UBC Table 18 -I -B. The
1997 UBC specifies that slab -on -ground foundations (floor slabs) on soils with an
expansion index greater than 20 require special design considerations in accordance
with 1997 UBC Section 1815. The design procedures outlined in 1997 UBC
' Section 1815 are based on a plasticity index of the different soil layers existing within
the upper 15 feet of the building site. Based on subsurface stratigraphy and distribution
tof the different soil types, we have assumed an effective plasticity index of 17 in
accordance with 1997 UBC Section 1815.4.2.

post -tensioned slabs may be used. The actual design of post -tensioned slabs is referred
to the project structural engineer who is qualified in post -tensioned slab design, using
sound engineering practices. The post -tensioned slab -on -ground should be designed
in general conformance with the design specification os 1997 UBC Section 1816.
Alternate designs are allowed per 1997 UBC Section 1806.2 that addresses the effects
of expansive soils when present. However, to assist the structural engineer in his
design, the following parameters are recommended.

SOIL CHEMISTRY
Laboratory test results indicate onsite soils contain negligible soluble -sulfate contents.
As such, concrete in contact with soil may utilize Type I or II Portland cement. The
laboratory test data for chloride concentration, resistivity and pH indicate onsite soils
may be moderately corrosive to buried steel in direct contact with onsite soils.
RETAINING WALLS
Footing Embedments
The base of retaining -wall footings constructed on level ground may be founded at a
minimum depth of 12 inches below the lowest adjacent final grade. Where retaining
walls are proposed on or within 15 feet from the top of any adjacent descending fill
slope, the footings should be deepened such that a minimum horizontal setback of H/3
(one-third the slope height) is maintained between the outside bottom edges of the
footings and the slope face; however, the minimum footing setback should be 5 feet.
The above -recommended minimum footing setbacks are preliminary and may require
revision based on site-specific soil and/or bedrock conditions. All footing trenches

should be observed by the project geotechnical consultant to verify that the footing
trenches have been excavated into competent -bearing soils and/or bedrock and to the
minimum embedments recommended above. These observations should be performed
prior to placing forms or reinforcing steel.
Active and At -Rest Earth Pressures
An active lateral -earth pressure equivalent to a fluid having a density of 40 pounds per
cubic foot (pcf) be used for design of cantilevered walls retaining a drained, level
backfill. Where the wall backfill slopes upward at 2:1 (h:v), the above value should
be increased to 63 pcf. All retaining walls should be designed to resist any surcharge
loads imposed by other nearby walls or structures in addition to the above active earth
pressures.
For design of retaining walls that are restrained at the top, an at -rest earth pressure
equivalent to a fluid having density of 60 pcf should tentatively be used for walls
supporting a level backfill. This value should be increased to 95 pcf for an ascending
2:1 (h:v) backfill.
Drainage
A perforated pipe -and -gravel subdrain should be installed behind all retaining walls
to prevent entrapment of water in the backfill. Perforated pipe should consist of 4 -inch
minimum diameter PVC Schedule 40 or ABS SDR -35, with the perforations laid
down. The pipe should be embedded in 1.5 cubic feet per foot of 0.75- to 1.5 -inch
open -graded gravel wrapped in filter fabric. Filter fabric may consist of Mirafi 140N
or equivalent.
In lieu of a pipe and gravel subdrain, weepholes or open vertical masonry joints may
be considered for retaining walls not exceeding a height of approximately 3 feet.

Weepholes, if used, should be 3 inches minimum diameter and provided at minimum
intervals of 6 feet along the wall. Open vertical masonry joints, if used, should be
provided at 32 -inch minimum intervals. A continuous gravel fill, 12 inches by 12
inches, should be placed behind the weepholes or open masonry joints. The gravel
should be wrapped in filter fabric to prevent infiltration of fines and subsequent
clogging of the gravel. Filter fabric may consist of Mirafi 140N or equivalent.
The backfilled portions of retaining walls should be coated with an approved
waterproofing compound to inhibit infiltration of moisture through the walls.
Temporary Excavations
To facilitate retaining -wall construction, the lower 5 feet of temporary slopes may be
cut vertical and the upper portions exceeding a height of 5 feet should then be cut back
at a maximum gradient of l :1 (h:v) for the duration of construction. However, all
temporary slopes should be observed by the project geotechnical consultant for any
evidence of potential instability. Depending on the results of these observations, flatter
temporary slopes may be necessary. The potential effects of various parameters, such
as weather, heavy equipment travel, storage near the tops of the temporary excavations
and construction scheduling should also be considered in the stability of temporary
slopes.
Wall Backfill
All retaining -wall backfill should be placed in 6- to 8 -inch maximum lifts, watered or
air-dried as necessary to achieve near -optimum -moisture conditions and compacted in
place to a minimum relative compaction of 90 percent.

Construction on or Near the Tops of Descending Slopes
Continuous footings for masonry block walls proposed on or within 7 feet from the top
of any descending slope should be deepened such that a minimum horizontal clearance
of 5 feet is maintained between the outside bottom edge of the footing and the slope
face. The footings should be reinforced with a minimum of two No. 4 bars, one top
and one bottom. Plans for any top -of -slope block walls proposing pier and grade -beam
footings should be reviewed by Petra prior to construction.
Construction on Level Ground
Where masonry block walls are proposed on level ground and at least 5 feet from the
tops of descending slopes, the footings for these walls may be founded at a minimum
depth of 12 inches below the lowest adjacent final grade. These footings should also
be reinforced with a minimum of two No. 4 bars, one top and one bottom.
Construction Joints
In order to mitigate the potential for unsightly cracking related to the effects of
differential settlement, positive separations (construction joints) should be provided
in the walls at horizontal intervals of approximately 25 feet and at each comer. The
separations should be provided in the blocks only and not extend through the footings.
The footings should be placed monolithically with continuous rebars to serve as
effective "grade beams" along the full lengths of the walls.

CONCRETE FLATWORK
Thickness and Joint Spacing
To reduce the potential of unsightly cracking, concrete sidewalks and patio -type slabs
should be at least 3.5 inches thick. Concrete -driveway slabs should be at least 4 inches
thick.
Subgrade Preparation
As a further measure to minimize cracking of concrete flatwork, the subgrade soils
below concrete-flatwork areas should first be compacted to a minimum relative density
of 90 percent and then thoroughly wetted to achieve a moisture content that is at least
equal to or slightly greater than optimum moisture content. This moisture should
extend to a depth of 12 inches below subgrade and maintained in the soils during
placement of concrete. Pre -watering of the soils will promote uniform curing of the
concrete and minimize the development of shrinkage cracks. A representative of the
project soils engineer should observe and verify the density and moisture content of the
soils and the depth of moisture penetration prior to placing concrete.
PLANTERS
Area drains should be extended into all planters that are located within 5 feet of
building walls, foundations, retaining walls and masonry block garden walls to
minimize excessive infiltration of water into the adjacent foundation soils. The surface
of the ground in these areas should also be sloped at a minimum gradient of 2 percent
away from the walls and foundations. Drip -irrigation systems are also recommended
to prevent overwatering and subsequent saturation of the adjacent foundation soils.

UTILITY TRENCHES
All utility -trench backfill within street right-of-ways, utility easements, under
sidewalks, driveways and building -floor slabs, 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 l- 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, such as under building -floor slabs, 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 1 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.
Where utility trenches are proposed parallel to any building footing (interior and/or
exterior trenches), the bottom of the trench should not be located within a t :1 (h:v)
plane projected downward from the outside bottom edge of the adjacent footing.

SLOPE LANDSCAPING AND MAINTENANCE
The engineered slopes within the subject tract are considered grossly and surficially
stable and are expected to remain so under normal conditions provided the slopes are
landscaped and maintained thereafter in accordance with the following minimum
recommendations.
• Compacted -earth berms should be constructed along the tops of the engineered fill
slopes to prevent water from flowing directly onto the slope surfaces.
' Provided the above recommendations are followed with respect to slope drainage,
maintenance and landscaping, the potential for deep saturation of slope soils is
considered very low.
1
�5
• The slopes should be landscaped as soon as practical when irrigation water is
available. The landscaping should consist of deep-rooted, drought -tolerant and
maintenance -free plant species. A landscape architect should be consulted to
'
determine the most suitable groundcover. If landscaping cannot be provided within
a reasonable period of time, jute matting (or equivalent) or a spray -on product
designed to seal slope surfaces should be considered as a temporary measure to
'
inhibit surface erosion until such time permanent landscape plants have become
well-established.
'
• Irrigation systems should be installed on the engineered slopes and a watering
program then implemented which maintains a uniform, near -optimum moisture
condition in the soils. Overwatering and subsequent saturation of the slope soils
should be avoided. On the other hand, allowing the soils to dry -out is also
detrimental to slope performance.
t•
Irrigation systems should be constructed at the surface only. Construction of
sprinkler lines in trenches is not recommended.
'
• During construction of any terrace drains, downdrains or earth berms, care must be
taken to avoid placement of loose soil on the slope surfaces.
• A permanent slope -maintenance program should be initiated for major slopes not
maintained by individual homeowners. Proper slope maintenance must include the
'
care of drainage and erosion -control provisions, rodent control and repair of leaking
or damaged irrigation systems.
' Provided the above recommendations are followed with respect to slope drainage,
maintenance and landscaping, the potential for deep saturation of slope soils is
considered very low.

• Property owners should be advised of the potential problems that can develop when
drainage on the building pads and adjacent slopes is altered in any way. Drainage
can be altered due to the placement of fill and construction of garden walls,
retaining walls, walkways, patios, swimming pool, spas and planters.

APPENDIX A
LABORATORY TEST CRITERIA
' Laboratory Maximum Dry Density
' Maximum dry density and optimum moisture content were determined for selected samples of soil and bedrock
materials in accordance with ASTM Test Method D1557. Pertinent test values are given on Plates A-) and A-2.
' Expansion Potential
' Expansion index tests were performed on selected samples of soil and bedrock materials in accordance with ASTM
Test Method D4829. Expansion potential classifications were determined from 1997 UBC Table 18-1-B on the basis
of the expansion index values. Test results and expansion potentials are presented on Plates A-3 and A-4.
Soil Chemistry
' Chemical analyses were performed on selected samples of onsite soil to determine concentrations of soluble sulfate
and chloride, as well as pH and resistivity. These tests were performed in accordance with California Test Method
Nos. 417 (sulfate), 422 (chloride) and 643 (pH and resistivity). Test results are presented on Plate A-5.
' Atterbere Limits
' Atterberg limit tests (Liquid Limit and Plastic Index) were performed on selected samples to verify visual
classifications. These tests were performed in accordance with ASTM Test Method D4318. Test results are presented
on Plate A-6.

CAUTION: The digitized data
points used
to model faults are
'
limited in number and
have
been digitized
from small
scale maps (e.g., 1:750,000
scale).
Consequently,
'
the estimated fault
-site -distances
may be
in error b
y
several kilometers.
Therefore,
it
is important that
'
the distances be carefully
checked
for accuracy
and
' adjusted as needed,
before
they are
used in
design.
