1.0 SCOPE OF WORK
The scope of work performed for this investigation included a review of the readily available
geologic literature pertaining to the site, obtaining representative soil samples and logging soil
materials encountered in the exploratory borings, laboratory testing of the collected samples,
conducting Cone Penetration Tests (CPT), engineering analysis of the field and laboratory data
and preparation of this foundation report.
The purpose of this report is to evaluate the general soil conditions at the project site, to evaluate
their engineering properties, and to provide foundation design recommendations for the proposed
project. The approximate location of the site is shown on the Site Map (Plate I-1) in Appendix I of
the report.
Due to limitations inherent in geotechnical investigations, it is neither uncommon to encounter
unforeseen variations in the soil conditions during construction nor is it practical to determine all
such variations during an acceptable program of drilling and sampling for a project of this scope.
Such variations, when encountered, generally require additional engineering services to attain a
properly constructed project. We, therefore, recommend that a contingency fund be provided to
accommodate any additional charges resulting from technical services that may be required during
construction.
The geotechnical recommendations presented in this report are intended for design input and are
not intended to be used as specifications. These recommendations should not be used directly for
bidding purposes or for construction cost estimates.
2.0 PROJECT DESCRIPTION
The City of Tracy proposes to replace the existing 11th
Street East Tracy Overhead, which crosses
Union Pacific Railroad (UPRR) tracks and North MacArthur Drive in the City of Tracy,
California. The existing overhead is a 34-span structure and was originally built in 1936. The
existing structure consists of reinforced concrete T-beams and steel girders, and the superstructure
is founded on timber piles, but the foundation detail is not available. The bridge was widened in
1960, and the widened portion is supported on steel piles (10BP42).
The project will replace the existing overhead structure with a shorter structure of about 291 feet
long (along centerline) in combination with retaining walls and embankment fill at the approaches.
The replacement structure will provide for a typical section that is about 89 feet wide in order to
accommodate two 12-foot wide through traffic lanes in each direction, 8-foot wide shoulders
which will serve as Class II bicycle lanes, and 8-foot wide separated sidewalks on each side that
are protected with traffic side barriers. Triangular overlook areas are planned on both sides of the

structure, and this is resulting from skewing the girders relative to the centerline of the roadway. It
is planned to use large diameter Cast-In-Drilled-Hole (CIDH) piles for foundation support.
A temporary on-site detour will be constructed south of the existing alignment to allow the existing
structure to be removed and the new overhead to be constructed in one stage on the same
horizontal alignment as the existing structure. The temporary detour structure will be about 230
feet long and 30 feet wide. It is also planned to use CIDH piles for foundation support.
Most of the permanent embankment will be supported by two-tiered Mechanically Stabilized
Embankment (MSE) walls with design height up to about 40 feet. Caltrans standard MSE wall
design will be adopted. A short cantilever retaining wall (Caltrans Standard Type 5) is planned
along the northeastern side of the new embankment.
3.0 EXCEPTIONS TO POLICY
Normal procedures were assumed for construction of the bridge structure throughout our analysis
and represent one of the bases of recommendations presented herein. The investigation and design
for the proposed foundations have followed Caltrans policy. Exception to policy is not needed.
4.0 FIELD INVESTIGATION AND TESTING PROGRAM
Three Cone Penetration Tests (CPT) were performed in November 2007 in order to help the
designer to establish the design strategy for the proposed project. During PS&E design phase, four
more borings were drilled in August and September 2010 (up to a maximum depth of 121.5 feet
below the existing ground surface), and three more CPTs were performed in September 2012 with
depths ranging from 50 to 122 feet.
The test borings were advanced with a truck-mounted drill rig. Borings R-10-005 and R-10-007
were advanced by using hollow stem augers above groundwater then switched to rotary wash
drilling method when groundwater was encountered. Borings R-10-004 and R-10-009 were
advanced primarily by rotary wash drilling method.
Selected samples were obtained from 2.5-inch I.D. Modified California (MC) sampler and
1.4-inch I.D. Standard Penetration Test (SPT) sampler at various depths. The samplers were
driven into subsurface soils under the impact of a 140-pound hammer having a free fall of 30
inches. The blow counts are presented on the Log of Test Boring (LOTB) in Appendix II. When
correlating standard penetration data, the blow counts for the MC Sampler may be converted to
equivalent SPT blow counts by multiplying a conversion factor of 0.65. The samples were sealed
and transported to our laboratory for further evaluation and testing. The field investigation was
conducted under the supervision of our field engineer who logged the test borings and prepared the
samples for subsequent laboratory testing and evaluation.

The CPTs were performed by Gregg Drilling & In Situ, Inc. of Martinez, CA. The CPTs were
conducted by using a 20-Ton capacity cone with a 60-degree cone attached to a 1.7-inch diameter
(tip area of 55 cm2) rod. The soil resistance exerted to the tip and side of the cone were recorded
and correlated to “Soil Behavior Type”, classification and strength characteristics.
The bore logs presented in Appendix II were prepared from the field logs which were edited after
visual re-examination of the soil samples in the laboratory and results of classification tests on
selected soil samples as indicated on the logs. The abrupt stratum changes shown on these logs
may be gradual and relatively minor changes in soil types within a stratum may not be noted on the
logs due to field limitations.
5.0 LABORATORY TESTING PROGRAM
Laboratory tests were performed on selected samples in the laboratory to evaluate the physical and
engineering properties of the subsoils. The tests performed for the study include the following:
Laboratory determination of Moisture (California Test Method 226), Unit Weight (California Test
Method 212), Atterberg Limits (California Test Method 204), Grain Size Analysis (California Test
Method 202), Unconfined Compression Test (California Test Method 221), Resistivity and pH
Test (California Test Method 643), Sulfate Content (California Test Method 417), Chloride
Content (California Test Method 422) and Consolidation Test (California Test Method 219). The
laboratory test results are attached in Appendix IV.
6.0 SITE GEOLOGY AND SUBSURFACE CONDITIONS
Site Geology 6.1
General geologic features pertaining to the site were evaluated by reference to the Geologic
Map of the San Francisco – San Jose Quadrangle, by D. L. Wagner, E. J. Bortugno and R. D.
McJunkin (CDMG, Map No. 5A, 1990). Based on the publication, the project site subsoils
generally consist of alluvium fan deposits (Qf).
Subsurface Conditions 6.2
We have reviewed the as-built LOTB (Caltrans 1963) of the existing East Tracy Overhead (Br.
No. 29-0005). Additional four borings and six CPTs were conducted under our scope of work.
The subsoils generally consist of interbedded medium stiff to stiff clayey silt and loose to
slightly compact silty sand. Two major sand layers were encountered at about 20- to 25-foot
and 60- to 75-foot depths, and the sand layers are more prominent on the west side of the
proposed overhead structure. Other sporadic, relatively thin sand lenses were encountered at
various depths. The CPTs also show predominantly fine grained materials at the site with
interbedded layers of sands with varying thicknesses of 2 to 10 feet. Boring R-10-007

encountered very dense silty gravel at the bottom of the boring at about Elev. -70 feet.
CPT-12-001 was also terminated at the same depth due to practical refusal.
Groundwater 6.3
Based on the as-built boring data, groundwater was encountered at Elev. 35 to 37 feet
(approximately 13 to 15 feet below the grade) during field exploration in 1956. Per Pore
Pressure Dissipation Test results conducted in November 2007, groundwater was measured
between 9.3 feet and 12.5 feet below existing grade. According to the explorations conducted
during the PS&E design phase, groundwater was encountered at about 18 and 14 feet below
existing grade in Borings R-10-005 and R-10-007, respectively, and groundwater was
measured at about 12.4 feet and 15.8 feet below existing grade from the Pore Pressure
Dissipation Test results conducted in September 2012
The groundwater encountered/measured in the boring and CPT data are relatively consistent.
However, please note that groundwater may vary with the passage of time due to seasonal
groundwater fluctuation, surface and subsurface flows, ground surface run-off, and other
factors that may not be present at the time of investigation. We have assumed groundwater at
10 feet below existing grade for design purpose.
7.0 SCOUR EVALUATION
The subject was considered and was determined to be not applicable for the project.
8.0 CORROSION EVALUATION
The corrosion investigation for this project was performed on selected samples in general
accordance with the provisions of California Test Methods 643, 417 and 422. A summary of the
corrosion test results is presented in the following table.

9.0 SEISMIC RECOMMENDATIONS
Seismic Sources 9.1
The project site is located in a seismically active part of northern California. Many faults
existing in northern California are capable of producing earthquakes and may cause strong
ground shaking at the site.
Maximum moment magnitudes (MMax) of some of the closest faults in the area are based on
2007 Caltrans Deterministic PGA Map and ARS Online Report. These maximum moment
magnitudes represent the largest earthquake a fault is capable of generating and is related to the
seismic moment. The earthquake data of the active faults in the project vicinity are
summarized below.
TABLE 2 – EARTHQUAKE DATA

(25) 6.7 Reverse Approx. 4.75 miles
Greenville fault zone
(350, 352) 6.6
Right-Lateral-Strike-Slip
(RLSS) Approx. 14 miles
Seismic Hazards 9.2
Potential seismic hazards may arise from three sources: surface fault rupture, ground shaking
and liquefaction. Since no active faults pass through the site, the potential for fault rupture is
relatively low. As shown on the Fault Map (Plate V-1), the closest active fault is located at
about 4.75 miles from the site. Based on available geological and seismic data, the possibility
of the site to experience strong ground shaking may be considered medium to high.
Liquefaction Potential 9.3
Potential seismic hazards may arise from three sources: surface fault rupture, ground shaking
and liquefaction. Since no active faults pass through the site, the potential for fault rupture is
relatively low. As shown on the Fault Map (Plate V-1), the closest active fault is located at
about 4.75 miles from the site. Based on available geological and seismic data, the possibility
of the site to experience strong ground shaking may be considered medium to high.
For liquefaction analyses, we have adopted Peak Ground Acceleration (PGA) of 0.465g for the
permanent structure and 0.227g for the temporary detour structure (see Section 9.4 for more
discussions). The liquefaction potential was evaluated in accordance with the methods
proposed by Youd, et al. (2001), primarily using the boring data that were performed in August
and September 2010. As indicated by recent advances in soil liquefaction engineering (Bray,
Drake Haglan & Associates
Job No. 2005-151-PSE (11th
Street OH)
March 25th
, 2014
Page 6
2006), for soils with sufficient fines content so as to separate the coarser particles and control
behavior, liquefaction appears to occur in soils where these fines are either non-plastic or are
low plasticity silts and/or silty clays (PI<12%, and LL<37%), and with high water content
relative to their liquid limit (w> 0.85LL).
In general, liquefaction hazards are most severe in the upper 50 feet of the surface as mentioned in
Special Publication 117A (CGS, 2008). In our opinion, the impact due to the potential liquefiable
soils below 50 feet is considered insignificant, especially when the layer is relatively thin and
discontinuous. Therefore, liquefaction potential for soils below 50 feet was not evaluated.
Based on the boring data, some of the fine-grained materials encountered have relatively low
plasticity and high natural moisture contents. According to the criteria suggested by Bray (2006),
these materials are expected to have “sand-like” behavior. Therefore, the liquefaction potential at
the project site was evaluated primarily based on the boring data. Based on the analysis results,
these soils may experience temporary loss of strength due to 100% development of pore pressure
with the higher level of design earthquake for the permanent structure (PGA of 0.465g). The soil
layers that may be subject to liquefaction are summarized in the following table. Based on the
analysis results, we have assumed a layer of liquefiable soils between Elev. 12.5 and 25 feet when
evaluating pile capacity and embankment stability.

5 to 7(*)
~1.0
* Note: The Atterberg limits were referred to the test results from R-10-007 at the similar depths.
For the temporary detour structure, the factor of safety (FS) against liquefaction is generally
greater than 1.0. The samples with FS less than 1.0 appear to be sporadic and not continuous.
Therefore, the overall impact due to liquefaction is considered negligible, especially when the
service life of the temporary structure is anticipated to be about 24 months. Liquefaction was not
considered for foundation design for the temporary structure.
Seismic Design Criteria 9.4
The recommended acceleration response spectrum (ARS) curves were developed during 35%
design phase based on the 2007 Caltrans Deterministic PGA Map and the Caltrans ARS Online
Drake Haglan & Associates
Job No. 2005-151-PSE (11th
Street OH)
March 25th
, 2014
Page 7
(Ver. 1.0.4). The ARS curves were presented in our Preliminary Foundation Report (dated
April 28th
, 2011), and the type of structure and foundation was selected in June 2011.
The development of the design ARS curve is based on several input parameters, including site
location (longitude/latitude), average shear wave velocity for the top 30 m/100 feet (VS30m),
and other site parameters, such as fault characteristics, site-to-fault distances. The design
methods incorporate both deterministic and probabilistic seismic hazards to produce the
Design Response Spectrum. According to the design manual, we have also compared with the
probabilistic response spectrum from 2008 USGS Deaggregation Hazard (beta) web site for
the 5% in 50 years probability of exceedance (or 975 year return period).
The average shear wave velocity (Vs) for the top 30m (100 feet) at the site was estimated by
using established correlations and the procedure provided in the Design Manual (Ver. 1.0,
August 2009). Shear wave velocity was also calculated based on the measurement from the
Seismic Cone Penetrometer Testing (SCPTu) where Vs was measured in 5-foot interval
through 100 feet.
As discussed in the previous section, some of the submerged, low-plastic soils encountered in
the borings may be subject to liquefaction during strong seismic event. When estimating the
VS30m, we have modeled the potential liquefiable soils as soft clay with residual shear strengths
per Kramer and Wang (2007) as cited in Caltrans guideline. For developing the ARS curve, we
have considered both profiles: (1) liquefaction case; and (2) non-liquefaction case. Based on
our calculation, we have estimated VS30m of 185 m/s and 230 m/s for liquefaction case and
non-liquefaction case, respectively. According to the analysis results, the recommended ARS
curve for the permanent overhead structure is governed by the data from 2008 USGS
Deaggregation Hazard (beta) with VS30m of 185 m/s.
For the temporary detour structure, the service life of the structure will only be during
construction and is expected to be about 24 months. Therefore, the seismic design was
determined based on 10% in 10 years probability of exceedance per Caltrans
Memo-To-Designer 20-12 (MTD, February 2003). We have utilized the USGS Deaggregation
Hazard (beta) website to generate the design ARS curve. The “10% in 10 years probability of
exceedance” is not available from the website. Consequently, we have assumed 50% in 75
years probability of exceedance with a mean return period of 108 years, which is on the similar
order of 10% in 10 years probability of exceedance (return period of 95 years), for generating
the design spectrum. We have conservatively adopted the same average VS30m of 185 m/s as
the permanent structure.

10.0 AS-BUILT FOUNDATION DATA
The existing bridge is a 34-span structure and was originally built in 1936, and the structure is
founded on timber piles. There is no as-built information available for the original structure, and
the foundation detail is unknown. The structure was widened in 1960, and the associated as-built
plans (Widening East Tracy Overhead, Br. No. 29-05, Caltrans, 1958) were provided by the
designer.
According to the as-built plans, the widened portion of the structure is supported on H piles
(10BP42) with design load of 45 tons. The specified pile tip elevation is at Elev. -10 feet and the
estimated tip elevation is at Elev. -30 feet. The pile driving records shown on the as-built LOTB
indicate that the piles were driven to an average tip elevation between Elev. -27 to -30 feet.
11.0 FOUNDATION RECOMMENDATIONS
General 11.1
This report was prepared specifically for the proposed project as described earlier. Normal
procedures were assumed for construction of the bridge structure throughout our analysis and
represent one of the bases of recommendations presented herein. Our design criteria have been
based upon the materials encountered at the site. Therefore, we should be notified in the event
that these conditions are changed, so as to modify or amend our recommendations. In addition,
bridge plans should be reviewed by our office prior to finalizing the plans to see that the intent
of our recommendations is included in the plans.
Foundation 11.2
Based on the subsurface condition, the subsoils at the project site consist of predominantly
fine-grained materials with some sand layers, and groundwater level appears relatively
shallow. Liquefiable soils have been identified within the project limit, which was considered
for foundation design that is associated with seismic loading. Per discussion with the designer,
Drake Haglan & Associates
Job No. 2005-151-PSE (11th
Street OH)
March 25th
, 2014
Page 9
96-inch diameter CIDH piles will be used for foundation support for the permanent structure,
and 42-inch diameter CIDH piles will be used for the temporary detour structure.
Caltrans typically uses Load and Resistant Factor Design (LRFD) for the bents and Working
Stress Design (WSD) for the abutments. However, for this project, the abutments were
specifically designed with pile columns instead of a tall abutment wall. The primary purpose is
to minimize the lateral earth pressure acting on the abutments so that the construction cost can
be reduced. Per our discussion with the designer, the abutments are expected to behave more
like bents, and pipe keys will be used to connect the substructure to the superstructure.
Consequently, the abutments will be designed per LRFD as bent foundations. Based on
information provided by the designer, the cut-off elevations of the CIDH piles at the abutments
are at Elev. 50 feet for both the permanent overhead and the detour structures.
The strength parameters used for foundation design are presented in Appendix V. We have
reviewed the available boring and CPT data and primarily focused on CPT-12-001,
CPT-07-002 and R-10-007 to develop the strength parameters for designing the proposed
CIDH piles. The pile capacity of the CIDH piles was estimated based on the procedures shown
in AASHTO LRFD Bridge Design Specification, i.e. Reese and O’Neil (1999). The pile
capacity of the CIDH pile will be derived primarily from frictional resistance along the pile
shafts, and end bearing capacity was not included when estimating the pile capacity. We have
utilized computer program “Shaft” (ENSOFT, v6.0) for calculation purpose.
For the proposed pile type, the recommended minimum pile spacing is three times the pile
diameter (3D, center-to-center) to minimize the group effect for vertical pile capacities. When
estimating the vertical pile capacity for extreme limit state, the contribution within the
potential liquefiable soil layers was neglected, and down drag load was considered.
The foundation design information provided by the designer and foundation recommendations
are presented in the following tables. Based on the load demand and subsoil information, the
recommended specified pile tip elevations are also shown in the Pile Data Table per Caltrans
MTD 3-1.

The lateral pile analyses were performed by the structure engineer and the design tip elevations
were provided to us. The pile group settlement was evaluated per AASHTO LRFD Bridge
Design Specifications. Based on the subsurface condition and the recommended waiting
period of the new embankment, it is our opinion that pile group settlement should not be a
design concern. The analysis results indicate that the induced settlement due to the pile group
is within the tolerable limits, and the pile group settlement does not govern the pile design.
According to our analysis, the estimated pile length of the 96-inch diameter CIDH piles will be
120 feet, and the 42-inch diameter CIDH will be 85 feet. For such long piles, temporary casing
is recommended to minimize the construction difficulty due to potential raveling or caving. In
our opinion, the use of casing oscillator/rotator techniques for CIDH construction may be
considered to facilitate the pile construction. This method has been successfully adopted in
various projects throughout California. More discussions regarding construction
considerations of the proposed CIDH piles are presented in Section 14.2.
Lateral Pile Capacity 11.3
The lateral pile analyses were performed by the structure engineer based on the geotechnical
parameters recommended in this section. It is our understanding that the lateral design does
not govern the length of the piles.
Potentially liquefiable soils were identified within the project limit, which may lose their shear
strength during a strong seismic event. Based on the slope stability analysis (see Section
11.5.2), permanent ground deformation of the embankment and MSE walls, i.e. lateral
spreading, is expected due to the presence of the liquefiable soils.
Caltrans published “Guidelines on Foundation Loading and Deformation Due to Liquefaction
Induced Lateral Spreading” in February 2011 and was updated in January 2012. The
publication provides a step-by-step procedure to calculate lateral spreading induced foundation
loads under seismic loading. The guideline is limited in its application to traditional seated
abutments and bents. However, the proposed overhead structure is highly skewed, and the
abutments are designed as free standing piers. Thus, our lateral pile design is in general
accordance of this Caltrans guideline except where the guideline is not applicable to the
specifics of the project design.
Based on the subsurface condition, lateral load analyses were performed for the proposed
CIDH piles at Abutment 1 and Abutment 2 by using the LPILE program (ENSOFT, v6.0). The
recommended geotechnical parameters are presented in the following tables. The
recommended strength parameters have been revised from the values presented in our
Preliminary Foundation Report (PFR), dated April 2011, after further reviewing the additional
Drake Haglan & Associates
Job No. 2005-151-PSE (11th
Street OH)

Page 13
CPTs conducted in 2012. We have primarily focused on CPT-12-001, CPT-07-002 and
R-10-007 to develop the strength parameters for the pile design. The strength parameters
provided in the previous PFR appear to be more conservative.
The factors were estimated based on (1) a pile spacing of three times the pile diameter
(center-to-center), and (2) liquefiable soils at 25 to 37.5 feet below the pile head. Residual
shear strengths (Sr) of the liquefiable soils were estimated per Kramer and Wang (2007) as
cited in Caltrans guideline for seismic and post-liquefaction condition. The p-multipliers were
modified per Caltrans guideline to account for the weakening effect the liquefied soil exerts on
overlying and underlying non-liquefied strata.

Since the abutments are supported on 96-inch diameter CIDH piles with column extension,
single pile with tributary area approach (instead of the super pile approach) was considered for
the analysis as it is deemed more appropriate for the proposed abutment design. Per our
discussion with the designer, the abutments will be connected to the superstructure by pipe
keys.
Based on the procedure outlined in Caltrans lateral spreading guideline (Section 3.5),
displacement compatibility plots were prepared for both longitudinal and transverse directions
of the structure. The crustal displacement was estimated per Bray and Travasarou model
(2007) as cited in the Caltrans guideline, which is a function of yield coefficient (ky), PGA and
fault magnitude. The yield coefficients were obtained from slope stability analysis based on a
range of possible foundation restoring forces.
It is our understanding that this connection will equally distribute the inertial loads to the CIDH
piles. When estimating the foundation resistive forces, we used 50% of the inertial loads
provided by the structural engineer in combination with 100% of the kinematic loads as
recommended in the Caltrans guideline for our LPILE analysis, with various crustal
displacements. Passive soil resistance behind the abutments was considered for the analysis in
the longitudinal direction.
According to our evaluation, the estimated ground displacement under design seismic event is
approximately 2.6 inches along longitudinal direction and 2.5 inches along transverse
direction. To account for the uncertainties due to the highly-skewed design of the structure, a
ground displacement of 3.5 inches is recommended for design in both directions.
The results of the lateral spreading analyses are shown in the Appendix V of the report. It is
recommended that the structural engineer verify the displacement compatibility plots for more
accurate results.
Embankments and MSE Walls 11.4
MSE walls are planned to support the approach embankment and to accommodate
right-of-way and geometric constraints. Such wall system is generally considered more
economical particularly in fill situations, and it is popular for its high-load capacity, speedy
installation, durability, relatively low maintenance, and cost efficiency.
Based on the information provided by the designer, the embankments will be supported by
two-tiered MSE walls. We have conducted engineering analyses to provide recommendations
for bearing capacity, settlement and waiting period, and slope stability for global aspects of the
Drake Haglan & Associates
Job No. 2005-151-PSE (11th
Street OH)
March 25th
, 2014
Page 15
embankment and walls. The details of internal wall design, such as the length of the
reinforcement, will be performed by the designer.
11.4.1 Bearing Capacity of MSE Walls
MSE walls are more flexible and can accommodate much greater settlement than typical
cantilever concrete retaining walls. Therefore, for cohesive soils, bearing capacity will be
based on the effective strength parameters. The adequacy of the bearing capacity of the
foundation soils immediately upon completion of construction was evaluated based on the
overall stability of the MSE walls.
Based on the boring data, the subgrade materials consist of primarily lean clay. Drained
strength parameters, ϕ’ of 28 and c’ of 200 psf, were assumed for design purpose. Since
the base width of the wall varies and can be up to 30 feet, we have conservatively assumed
high groundwater level below the bottom of the MSE walls and adopted a uniform buoyant
unit weight of 65 pcf for design.
The bearing capacity is mainly a function of the base width. We have calculated the
nominal (ultimate) bearing capacities per equation 4‐ 22 of “Design and Construction of
MSE Walls and RSS” (FHWA‐NHI‐ 10‐ 024, November 2009) with various design base
widths (B). The results are presented in Appendix V.
As discussed, the bearing capacity is generally not a governing factor since the ground is
allowed to settlement under drained condition. The global slope stability immediately after
construction (short-term undrained condition) can be more critical. Detail analysis and
discussions are presented in Section 11.5.3 “Embankment Stability”.
11.4.2 Settlement Under Embankments and MSE Walls
Consolidation settlement is anticipated due to the proposed approach embankment and the
MSE walls. Consolidation tests were conducted on selected samples obtained from the
borings. We have reviewed and adopted correlations from various references with revision
to the site-specific laboratory test results for estimating the indexes for settlement
calculation. The estimation of pre-consolidation pressure is based Su/p per Skempton
(1957) and NAVFAC D.M. 7.1. The modified compression index (Cc/(1+e0)) and the
recompression index (Cr/(1+e0)) were estimated based on the laboratory test results and
were also compared to the correlation with natural moisture content based on Lambe and
Whitman (1969).

Page 16
Based on the subsurface condition, the site is underlain by predominantly fine-grained
materials. According to the proposed wall/embankment configuration, the estimated
ground settlements under the approach embankment may be on the order of 15 inches.
The analysis results indicate that majority of the anticipated settlements are in the
over-consolidated (OC) range and should occur relatively fast. However, a portion of the
consolidation settlement from the upper clay layer will be within the normal-consolidated
range. Consequently, a longer waiting period may be required. Based on our analysis, a
waiting period is recommended after the embankments have been built prior to pile
construction at abutments of the structures and the construction of the pavement. This is
intended to prevent the abutment piles from simultaneously experiencing both the down
drag load from the consolidation settlement and the structure loads. Settlement monitoring
is recommended and should be performed as per Caltrans Standard Test Method 112.
The analysis results are summarized in the following table.

Estimated
Settlement
Recommended
Waiting Period
Permanent Embankment
& MSE Walls 42± feet 15± inches 150 days
Temporary Detour
Embankment & MSE Walls 28± feet 9± inches 90 days
The settlement magnitude appears tolerable for Caltrans standard MSE walls. In Caltrans
District 4, we have seen previous MSE wall settlement data (Route 87, between Hedding
Street and I-880 in Santa Clara County, CA) on the order of 2 to 3 feet.
Wick Drain. The estimated time for the primary consolidation settlement to take place is
relatively long. Therefore, vertical wick drains may be considered to reduce the waiting
period. We have evaluated the use of wick drain installed at different spacing to expedite
primary consolidation settlement for cost-comparison purpose. References were made to
Terzaghi, Peck and Mesri (1996, Soil Mechanics in Engineering Practice, 3rd
edition) in
calculating the time factor, degree of consolidation, and settlement rate for the wick drain
system.
Based on our analysis, the recommended waiting period may be reduced to 30 days with
wick drains for the 40-foot-high embankment for the permanent structure prior to pile
construction based on the following assumptions:

1. Wick Drain Layout: Triangular pattern;
2. Wick Drain Spacing: 4 feet on centers;
3. Wick Drain Length: approx. 40 feet long below existing grade.
Ground Settlement at UPRR Tracks. The proposed abutments are located relatively close to
the existing railroad tracks. Consequently, the tracks may experience ground settlement
after the construction of the embankment. Based on our analysis, the ground settlement
induced by the embankment of the permanent structure may be on the order of 2 inches.
This settlement at the UPRR tracks is expected to be within the over-consolidation range,
which may take place during the construction of embankment. In our opinion, settlement
monitoring along the track should be implemented during construction. Therefore, the
tracks should be checked and may have to be re-leveled after the construction of the
embankment and the MSE walls.
11.4.3 Embankment Stability
The global stability of the proposed embankment and MSE walls was evaluated based on
the lateral spreading guideline by Caltrans. The stability of the MSE walls and the
embankments were evaluated under three conditions: (1) static condition (immediately after
construction), (2) seismic condition (pseudo-static with a seismic coefficient (k) and
residual shear strength for liquefaction condition), and (3) post-liquefaction condition (with
residual shear strength of liquefiable soils).
For determining the horizontal seismic coefficient for pseudo-static analysis, we have
referred to the “Guidelines for Structures Foundation Reports manual” (Ver. 2.0, 2006,
updated December 2009), which recommends that the seismic factor equal to one third of
the horizontal peak acceleration and not exceeding 0.2g.
Per Duncan and Wright (2005), short-term, undrained shear strength (non-liquefied)
parameters are recommended for analysis under seismic condition since liquefaction
generally is not expected to occur in conjunction with the peak ground acceleration.
However, according to the latest Caltrans guideline of lateral spreading, we have conducted
the pseudo-static analysis with the residual shear strengths (Sr) for the liquefiable soils. The
residual soil strengths (Sr) of the liquefiable soils were estimated per Kramer and Wang
(2007) as cited in Caltrans guideline.
Considering liquefaction is generally not expected to occur in conjunction with peak
ground acceleration. This approach (pseudo-static analysis coupled with residual shear
strengths) appears relatively conservative. Therefore, for seismic condition, the strengths of
Drake Haglan & Associates
Job No. 2005-151-PSE (11th
Street OH)
March 25th
, 2014
Page 18
the fine-grained materials were increased by 30% in the analysis due to dynamic loading
condition (per Ishihara, 1985), and strength increase because of the effect of consolidation
was also considered.
The stability analysis was performed by computer program “SLOPE/W” by GEO-SLOPE
International. The evaluation results are attached in Appendix V, and the results are
summarized in the following table.
TABLE 9: FACTOR OF SAFETIES FROM STABILITY ANALYSES
Location Factor of Safety (Longitudinal/Transverse)
Static Condition(1)
Seismic Condition Post-Liquefaction
Permanent 1.26/1.34 <1.0/<1.0 1.01/1.96
Temporary Detour 1.59/1.49 1.29/1.09 - (2)
Notes:
(1) Immediately after construction.
(2) The service period of the temporary detour is expected to be relatively short (about 24 months).
Therefore, seismic design should not be a design issue, and the factors of safety under seismic
condition appear satisfactory.
A ground displacement of 3.5 inches is recommended for design in both transverse and
longitudinal directions to account for the uncertainties due to the highly-skewed design of
the structure. Therefore, it is our opinion that the distance between the permanent structure
and the embankment/MSE wall be at least 7 inches (with a factor of 2). Lateral spreading
effect on piles is discussed in more detail in the previous section (section 11.3).
Traditional Retaining Wall - Retaining Wall No. 5 (Caltrans Standard Type 5) 11.5
Retaining Wall No. 5 will be located approximately 60 feet east of the northeastern edge of the
planned eastern abutment. It will extend eastward about 455 feet. It is planned to use Caltrans
Type 5 wall to support the proposed widening. The maximum wall height will be about 8 feet and
the approximate footing will be at about Elevation 43 feet.
Based on CPT-12-002, CPT-12-003 and R-10-007 conducted in the vicinity of the proposed wall,
the foundation subgrade soils consist of medium stiff to stiff lean clay with sand. Groundwater
was encountered between Elev. 36 feet to 39.6 feet during field exploration. The layer of soft to
medium stiff clay was encountered down to about Elev. 40 feet, which is close to the proposed
footing elevations. Therefore, it is recommended that the subgrade be over-excavated 3 feet
below the footing and replaced with compacted AB. This pad is expected to serve as a “load
distribution bridge” for reducing footing pressure and differential settlement. The boring data
indicate that the groundwater level is relatively close to the proposed footing elevation.
Consequently, should groundwater be encountered during excavation, Lean Concrete Base
(LCB) may be used instead of compacted AB for the backfill below the footing.
Drake Haglan & Associates
Job No. 2005-151-PSE (11th

Page 19
It is expected that ground settlement will be induced due to the construction of the MSE wall and
the embankment, which is about 16 feet away from the proposed Retaining Wall No. 5.
Therefore, it is recommended that the MSE wall and embankment be constructed first prior to the
construction of the retaining wall. The same waiting period as recommended in Section 11.4.2
should be applied.
With the recommended subgrade improvement, the recommended ultimate bearing capacity at
the bottom of the footing is 8 ksf under extreme limit state, and a bearing capacity of 3.6 ksf is
recommended under strength limit state. The estimated settlement under the effective width and
the footing pressure under service condition is on the order of 1.5 inches. In our opinion, Caltrans
standard Type 5 retaining wall is considered feasible.
12.0 STRUCTURAL PAVEMENT DESIGN
Based on the roadway profile provided by the designer, 11th
Street is an elevated roadway,
crossing over the existing UPRR tracks, and approach embankments are planned along the project
alignment. New pavement will be constructed mostly on import borrow materials. It is
recommended that the materials placed within 4 feet of the finish pavement subgrade be free of
organic or other deleterious materials and have minimum R-value of 15.
Based on the provided TI provided by the designer, the recommended pavement sections were
calculated by Caltrans design procedures based on an R-value of 15 (Highway Design Manual,
Section 630). The recommended structural pavement section data are tabulated in Table 10.

13.0 NOTES TO DESIGNER
It is recommended that the structure engineer verify the pile tip elevations when finalizing the pile
data table. Should the specified pile tip elevation required to meet lateral load demands exceed the
specified pile tip elevation given within this report, the Geotechnical Engineer must be contacted
for further recommendations.
14.0 CONSTRUCTION CONSIDERATIONS
General 14.1
To a degree, the performance of any structure is dependent upon construction procedures and
quality. Hence, observation of grading operations should be carried out by Caltrans and/or City
of Tracy. If the encountered subsurface conditions differ from those forming the basis of our
recommendations, this office should be informed in order to assess the need for design
changes. Therefore, the recommendations presented in this report are contingent upon good
quality control and these geotechnical observations during construction.
Construction of CIDH Concrete Piles 14.2
Caltrans standard specification for “Cast-in-Place Concrete Piling” should apply for the
construction of CIDH piles. Groundwater is expected during pile construction. The use of
temporary casing and slurry construction for CIDH pile installation is anticipated.
For the proposed CIDH piles, temporary casing is recommended to minimize the construction
difficulty due to potential raveling or caving. In our opinion, the use of casing
oscillator/rotator techniques for CIDH construction may be considered to facilitate the pile
construction. This method has been successfully adopted in various projects throughout
California.
Access tubes should be provided to allow for construction quality control (Gamma-Gamma
Logging and/or Cross-Hole Sonic Logging). Due to presence of granular material, raveling or
caving is expected which may require additional drilling and cleaning effort and may increase
the concrete volume for the piles. It is prudent to make the contractor aware of these
conditions so that he takes appropriate steps to comply with the standards and maintain the
integrity of the CIDH concrete piles. Mitigation and repair procedures for CIDH anomaly
should be anticipated.
All piles excavations should be observed by the geotechnical engineer or regulatory agency
prior to the placement of reinforcement and concrete so that if conditions differ from those
anticipated, appropriate recommendations can be made.

Settlement Monitoring 14.3
The settlement monitoring should be implemented per Caltrans Test Method 112. It is
recommended that the settlement points be installed along the center line of the embankment at
a 100-foot interval and extend to 500 feet from the abutment. Additional settlement points at
the proposed foundation location are also recommended to verify or shorten the recommended
waiting period in order to commence the foundation construction.
Demolition of the Existing Foundation 14.4
The proposed new overhead structure and MSE walls will be constructed along the same
alignment as the existing structure, which is a 34-span structure supported on pile foundation.
The proposed location of the new foundation should be selected away from the existing footing
to avoid conflict. In addition, if any existing pile is located under the leveling pad of the MSE
walls, the top of the piles should be demolished to have minimum 3 feet clearance from the
bottom of the leveling pad.
15.0 INVESTIGATION LIMITATIONS
Our services consist of professional opinions and recommendations made in accordance with
generally accepted geotechnical engineering principles and practices and are based on our site
reconnaissance and the assumption that the subsurface conditions do not deviate from observed
conditions. All work done is in accordance with generally accepted geotechnical engineering
principles and practices. No warranty, expressed or implied, of merchantability or fitness, is made
or intended in connection with our work or by the furnishing of oral or written reports or findings.
The scope of our services did not include any environmental assessment or investigation for the
presence or absence of hazardous or toxic materials in structures, soil, surface water, groundwater
or air, below or around this site. Unanticipated soil conditions are commonly encountered and
cannot be fully determined by taking soil samples and excavating test borings; different soil
conditions may require that additional expenditures be made during construction to attain a
properly constructed project. Some contingency fund is thus recommended to accommodate these
possible extra costs.
This report has been prepared for the proposed project as described earlier, to assist the engineer in
the design of this project. In the event any changes in the design or location of the facilities are
planned, or if any variations or undesirable conditions are encountered during construction, our
conclusions and recommendations shall not be considered valid unless the changes or variations
are reviewed and our recommendations modified or approved by us in writing.

Notes: Reference: 1. The correction factors CE (Energy Ratio), CB (Borehole Diameter), CR (Rod Length) and CS (Sampling Method-liner) are per Youd et al. (2001).2. For correction of overburden, CN = (1/v')
0.5 with a maximum value of 1.7. 3. The influence of Fines Contents are expressed by the following correction: (N1)60cs = + (N1)60
where and = coefficients determined from the following relationships for FC < 5% = 0, = 1.0 for 5% < FC < 35% = exp(1.76-(190/FC2)), = (0.99+(FC1.5/1000)) for FC > 35% = 5.0, = 1.24. For (N1)60,cs greater than 30, clean granular soils are too dense to liquefy and are classed as non-liquefiable.
