Subject: Mission Peak Property-
Kleinfelder Geotechnical Peer Review
Tracy:
Enclosed for your use is a copy of the geotechnical peer review by Kleinfelder, Inc., for the
Mission Peak Property, dated November 22nd
Please note that the review raises two issues that could impact the project design. The first
is the structural setback from the creek; adequate setback in conformance with the City
setback ordinance will need to be confirmed with cross-sections (although the proposed 100'
envimllmental setback shown on the Stage 1 Development Plan may provide more than
adequate stl'uctural setback). Tho second is the potential for several slides in the canyon
above" the dovelopment to bocome active Gnd block the drainage courCiO in the bottom of the
canyoll.
We would encourage you to address these comments prior to resubmitting the Stage 1 plan.
We can arrange a meeting with Kleinfelder, Inc., if necessary.
Please contact me at (925) 833-6635 if you have any questions on the above.

Subject: Mission Peak Property - Kleinfelder Geotechnical Peer Review _ Response to
Comments by Berlogar Geotechnical Consultants Regarding Initial Peer Review
Tracy:
Enclosed for your use is a copy of the geotechnical peer review by Kleinfelder, Inc" for the
Mission Peak Property, dated February 17, 2005. The peer review responds to comments in
the January 17 peer review letter from Berlogar Geotechnical Consultants, responding to an
earlier peer review letter of November 22,2004, from Kleinfelder.
The latest letter indicates genel'al closure on the issues raised in the initial peer review. Two
items noted by I<leinfelder will /,!,:quire further attention:
i) The eastGl'ly limit of Slide "/'\" (above the northerly edge of the developed area) will
need to be better defined_ The slide I'epair will need to continue to the east of the
developed areas (Lot 13) in ol'der to protect the developed areas. Further
investigation and repair of the potential slides in the canyon to the east of Lot 13 wi/I
not be necessary.
The presence of slides to the east of the developed area may result in ongoing erosion
of the slope toes and deposition of eroded material in the proposed storm drain
system. In order to prevent material from entering the storm drain and clogging the
system and/or impacting downstream water quality, it will be necessary to include a
sediment basin or trap at the system inlet (east of Lot 13) to decelerate and trap
material before it enters the system. The development plan will also need to provide
an overland release path through the project for storm water and debris in the event
the storm drain system is blocked.
2) The presence of piping within the area proposed for the water quality pond was noted.
This piping will require further investigation and possible remediation as part of the
development. "

BACKGROUND AND INITIAL PEER REVIEW
We have completed an initial technical peer review of the project and prepared a letter report titled
"Preliminw)J Geologic and Geotechnical Peer Re1.'icw Comments Pertaining to the Planned Mission
Peak Property Residential Development Proposed Along Tassajara Road in Dublin, California" dated
November 22, 2004 (File No. 51142/PW1). The initial review presented our professional opinions and
conclusions as they pertain to the geotecbnical aspect of tbe proposed residential development at that
stage. The completed initial technical peer review included the following items:
1. Detailed review of the following geotechnical report prepared by BGC:
. Design level Geotechnical Investigation, A1ission Peak Property, Tassajara Road, Alameda
County, California" dated September 19, 2003;
2. Observations made dming a site recOllllaissance visit to the site on November 12, 2004 by a

SCOPE OF CURRENT PEER REVIEW
BGC prepared a response letter titled '"Response to Peer Review, Tassajara Terrace e(ormerly Jiiission
Peak Property), Tassajara Road, Dublin, Califomia" and dated January 17, 2005 in which they
addressed our initial November 22, 20{J4 review comments for the project. The scope of this current
evaluation included the review of the BGC January 17, 2005 document and the above referenced RJA
development plan.
The following are our rcvieW-C0111111cnts concellllng the information reviewed.
cummNT REVIEW COMMENTS
Our reviewconU11cnts were developed based on our evaluation of tbe geotecbnical reports and related
desib'11 documents referenced above and our familiarity with the genera! gcologic,d/geotcchnica!
conditions ill the vicinity of the site from previous projects.
BGC has generally responded to our rev-iew COl1U11cnts satisfactorily except where noted below.
A, Landslide Characteriz:ation
Based on the most recent development plan prepared by RJA, it appears that the proposed layout
of the development has been modified to where Lot 13 is now situated approximately 500 feet to
the west of the pond present within the central drainage swale along the eastern portion of the
site. The initially proposed cu[,de,sac and residential lots in the vicinity of Landslide C are no
longer planned in that area. The eastem property line of Lot 13 is now proposed about ISO feet to
the west of the western margin of Landslide C. Accordingly, BGC does not plan on repairing
Landslide C as was initially planned and they do not believe that evaluating any postulated
landslide deposits beyond Landslide C to the east is needed.

While we concur with BGC that repairing Landslide C or characterizing the postulated landslide
deposits to the east are no longer necessary, it is our opinion tbat the eastem hmit of repair for
Landshde A should be better defined and that it should extend eastward well beyond Lot 13.
BGC evaluated tbe mapped landshde deposits along the axis of the prominent drainage swale
along the northeastern section of the property and evaluated the flooding potential that could
occur if reactivation of landslides in that area resulted in damming the swale. They concluded
that the relatively shallow landshde deposits occupy low positions on the slopes and that based on
the soil-like materials that comprise these deposits it is their opinion that such failures would not
foml competent blockmg packages along the axis of the swale. They noted that the potential for
blockages that would dam significant runoff is low because they believe that the runoff would
bypass and erode any failed slUlTY into the axis of the swale. We concur, especially now that the
planned development limits have been moved westward as discussed above.
B. Erosion of the Creek Banks
Based on our review of the modified' development plan and the topographic base map delineating
the setback zone associated with tbe creek, it is our opimon that the Water Quality Pond and the
residential pads are adequately setback from the creek in general conforn1ance with the City of
Dublin Ordinance No. 52,87.
BGC mapped soil piping (sink holes) in the general area where the Water Quality Pond is
proposed. Such soil piping features tend to extend in the subsurface and they could have
sigmficant adverse conditions on the integrity of the pond ifnot mitigated before the construction
of the pond. Accordingly, it is our opinion that the soil piping should be mapped m detail in that
area, the roofs of the pipes should be collapsed and the generated voids filled.
C. Fonndations
We concur with BGC
D. Retaining WaUs
BGC has indicated that the Keystone walls will have native soil backfill and have reconunended a
friction angle of 30 degrees for this materiaL This value is high fm the on,site clayey and silty
soils, except for soil derived from sandstone bedrock. BGC's remolded direct shear tests indicate
friction angles (except for remolded' sandstone) of 15 to 28 degrees with an average value of 22
degrees. BGC has also ack:nowledged the need to check global wall stability when the locations
and heights of the Keystone walls are conceptually detemlined. In addition to checking the
global stability, they should reevaluate their backfill design parameters based on the above
comment and the actual backfill soil type.
Checking the final wall design shouUd be a Condition of Approval before construction.
E. Prelimiuary Pavement Sections
Based on BGC's response comments, we understand that 2 to 3 percentage points (above
optimum moisture content) will be maintained in the soil subgrade underlying proposed pavement
areas until such areas are paved.

F. Slope Stability Analy~;is
BGC llsed effective stress parameters for all (except one) of their seismic analysis instead of
llsing total stress parameters. Nonetheless, the seismic factors of safety (FS) arc generally
acceptable. A relatively high cohesion value was used for one ofthe seismic analysis (next to the
creek), whIch was based on one laboratory test and no tension crack was assumed. It is our
opinion, however, that even with a lower cohesion and an assumed tension crack, the slope \vill
likely be stable.
G, Remedial Grading Plan
It is imperatIve that a remedial grading plan is developed for the site when the development
layout and the grading scheme are final. This should constitute a Condition of Approval for this
development. Without a remedial grading plan it is difficult to assess the potentially adverse
effects posed by landslide deposits, unstable colluvial zones, stability of cut and fill slopes,
cut/fill transition lots, and differential fill conditions across pad areas.
RECOMMENDED FOLLOW UP
The above comments are based on the information and the documents that have been provided to us for
review and our independent rcc01U1aissance observations at the project site. If additional pertinent
infom1ation Inay have been developed but not yet provided to us, we would be pleased to review such
information at the City's request.
The above comments should be addressed by the applicant and responses provided to us for our further
revIew. We would be pleased to meet with the City and the applicant's represcntatives to discuss these
review comments if that would be helpful.
LfMITATIONS AND CLOSURR
This review has been performed at the request of the City of Dublin. Our role has been to provide
teclmical advice to assist the City in its discretionary permit decisions. Our services have been limited to
the review of the documents identified in this letter and our observations at the site. We have employed
accepted geologic and geotechnical engineering procedures, and our professional opinions and
conclusions arc made in accordance with generally accepted geologic and geotechnical engineering
principles and practices that exist in the San Francisco Bay Area at the time this letter was wlitten. No
other WUlTanty is expressed or implied. Our review did not include any independent field explorations or
analysis, other than a brief site reconnaissance. Also, our review did not include checking of the
documents for confo1l11ance with state or local govelnmental codes or client requirements. This review
does not relieve the geotechnical engineer for this project from his sole responsibility as geoteclmical
Engineer-of-Record for the project.

Dear Mr. ~[artin:
INTRODUCTION
This report presents the results of our design level geotechnical investigation oC the Mission Peak
property located on the east side of Tassajara Road in Alameda County. California. The sile is
shown with respect to existing cu[tural features on the Vicinity Map (Plate I). We previously
perCol111ed a preliminary geotechnical investigation of the property and presented the results in a
report dated September 13,200 I (13GC Job No. 2566.1(0).
PROPOSED DEVELOPMENT
^ plan titled "Site Plan Alternative 'E'," dated Ivlay 13,2003, prepared by Ruggeri-.Jensen-Azar
8: !\ssoeiates (R.JA) was provided to us for use in this investigation. That plan shows the site
being developed into 97 single-family residential lots. Rear yard retaining walls up to 5 feet tall
will be built on some lots. Grading is shown to inelude cuts up to about 30 feet deep and fills up
to about 35 feet thick. The 3 horizontal to I vertical (3ll: 1 V) south and west-facing cut slopes
up to about 50 feet high and west-facing Jill slopes up to about 40 feet high, are also shown on
the plan. A water quality pond about 440 feet long and 90 feet wide is shown next to the
unnamed tributary of Tassajara Creek in the western part of the site. The grading is shown to be
limited to about the western half of the property. The grading is also shown to extend beyond the
property line into undeveloped land to the southeast and tying into future grading to the south.
We understand that a site grading plan has yet to be finalized and it is possible the grading shown
on the RJA plan could change.

results along with a brief evaluation arc included in Appendix D.
FINDINGS
REGIONAL GKOLOGY AND SEISiVHClTY
The property is situated within the Coast Ranges geon1Oq1hic province of C'aliilJrnia, which is
characterized by northwest trending, folded and lewlled moun'ain ranges. [n this part of the
province. sedimentary rocks of the Tassajara Formation. which is Pliocene to Pleistocene in age
(approximately 0.0] to :5.3 million years before present), underlie the area (Dibbke, 1980: Crane,
1988). The region has been folded and faulted during the past 3 milIion years duc to obliquc
strike-slip rclative motions between the Pacific Plate and North American Plate
The s;le docs not lie within an earthquake fault zone 1ur active I,mlts as defined by the State of
California (Davis (982). and no faults arc nElpped on the site. Ivlajor active bults in thc region
that intluence the seismicity of the site include the San Andreas, Hayward, Calaveras, and
GreenvilIe faults, located 30, 11,4, and 7 miles fi'om thc site, respectively (Bortugl1o, 1991).
According to Peterson et a!. (1996), estimated maximum moment magnitude (lvlw) earthquakes
on thcse faults arc as follows: San Andreas (1906 Segment), 7.9; Hayward (total length), 7.1;
Calaveras (north of Calaveras Reservoir), 6.8; and Greenville, 6.9. Recent studies by Unruh and
Sawyer (1997) postulate that the Mount Diablo uplift is underlain at depth by a "blind" thrust
tiullt system that may be capable of producing earthquakes of Mw M" to 6%. The distance from
the site to the postulated blind tIu'ust cannot be accurately measured but could be in the range of
2 to 4 miles.
SURFACE CONDITIONS
The approximately 67-acre site is irreguLJrly shaped, ranging roughly from 900 to 2,300 fixt
long west to east and 1 ,000 tor ,SOO feet wide north to south. Tassajara Road and a tributary 0['
Tassajara Creek border the western limits of the site. Open land horders the remainder of the site
to the north~ east and south.

The unnamed tributary of Tassajara Creek flows to the south-southwest into a 9,feet diameter
CMP culvert crossing under Tassajara Road. The creek channel is about 20 teet deep with about
I If: I V banks. The creek banks expose bare ground likely due to erosion and slope instabilitv.
/\n existing pond is located adjacent to the creek OLliS ide of the development area in the
notihwest corner of the site.
Two sinkholes about 6 to 10 leet wide and 2 reel deep were idef1titied along the top of the
eastern bank near Tassajara Road durif1g our preliminary investigation in 200 I. It appears the
northernmost sink hole has since developed into an erosional gully on the creck bank. An
additional sink hole about 4 feet \\ide and about 1 to 2 teet deep was observed during this
investigation near the wI' of the east creek bank, between the two previously observed sink
IlUles.
The northern portion of the site is dominated by an about 200 teet high ridge that trends west-
cast. Thi.s ridge slopes clown to the proposed development site at gradients as steep as about
11f:IV near the top but generally slopes between 1Y:,1f:IV to 31f:IV or less steep in the

along the toe of the ridge and into the tributary creek. A man-made berm is constructed across

Two smaller west,east trending ridge spurs separated by a small drainage swale extend into the
southern portion of the site from the east. The ridge spurs are between about 80 to 100 feet high
with side slopes as steep as 2y:'[-j: I Valong the northern slope of the northern spur and 31-1: I V or

The site is currently vacant with the exception of a well and well house. scattered knces and
metal tanks located near a dirt road that parallels the tributary creek and connects to Tassajara
Road. Site topography ranges in elevation from 450 fect in the tributary creek in the
southwestern portion of the site near Tassajara Road to about 705 fcet on the top of the northern

understand tbat tbe till was reportedly generated during tbe cleanout of tbe pond in tbe nortbwest
portion of tbe site outside of tbe proposed grading limits. Tbe approximate area of tlIl is sbown
on the site plan as Qaf. This existing tlll is considered bigbly organic and expansive. Artitlcial
till is also located in tbe nortbeast portion of the site east of the development area in the tcm11 of a
pond berm.
RESIDUAL SOILS
Residual soils, derived by in-place weatbering of the underlying parent bedrock, were
encountered in test pits excavated on ridgelincs and spur ridges. Tbc residual soils encountered
consisted of' dark gray and dark gray brolVn silt\, cia)' (CL-CI'I). At tbe time of Our invcstigatio!:
in August 2003, we observed desiccation cracks up to 3 inches wide and 2 to 3 feet deep in the
central pbne and along the slopes of the southern ridge spur. The typical thickness of residual
soil revealed by the test pits varied 1';'0111 about 2 to 4 feet. The residual soils have moderate to
high plasticity clIld arc considered highly expansive.
COLUJVIAL DEPOSITS
Colluvial deposits, generated by the downslope creeping of residual soils and/or their
transporlation by erosion, were revealed in test pits and borings ill swales and valleys. Areas
underlain by colluvium deposits are noted On the Geologic ['viap using the symbol "Qc." Where
encountered in test pits and borings, the colluvial deposits were found to consist of dark gray to
gray-brown to dark brown silty clay (Cr-I). Laboratory test results indicate that the colluvial soils
have high plasticity and are considered highly expansive.
ALLUVIAL DEPOSrTS
Alluvium is material that has been transpol1ed and deposited by way of ilowing water. A]luvial
deposits were noted within and adjacent to the unnamed tributary of Tassajara Creek. As
encountered in the test pits and borings, the alluvia] soils consisted generally of stiff to vcry still
sandy clay and silty clay (CL-CI-I), medium still to stiff clayey silt (ML), medium dense sandy
silt (ML), clayey sand (SC) and silty sand (SM). Tbc alluvia] deposits are marked by the
symbols "Qoa" (older alluvium) and "Qal" on the Geologic Map. Laboratory test results indicate
that the clayey alluvial soils have moderate to high plasticity and arc considered highly
expanSIve.
LANDSLIDE DEPOSITS
Regional landslide mapping hy the U.S Geological Survey (Nilscn, ] 975) showed several
landslicles on the sile, inciuding three in the area of the current proposed development. Duriug
Our 1001 investigation, we performed preliminary test pit exploration of these landslides. Our
current design-Ievel investigation also included test pits end borings in continned and suspected
landslide areas. The total infill'll1atiou resulted ill our depiction of three landslides in the arca of

the proposed devclopment. Landslides are depicted using the symbol "Qls" on the Geologic
Map. In addition, the three pertinent landslides me given the letter designations A, B, and C, as
shown on the Geologic Map. These three mapped landslides correspond to three of Nilsen's
(1975) interpreted landslides. There are additional likely or suspected landslide deposits
elsewhere on the l\lission Peak property, but these arc not discussed since they arc \vell outside
(north and east) of the proposed area of development, as shown on the Geologic Map.
Landslide A
Landslide A is located on the north side of the development. on the dominating suuthwest-being
hillside. The landslide's estimated plan-view dimensions are roughly 600 by -100 feet across, and
it has a maximum explored depth of 26 feet. Near its margins, it consists of clayey slide debris
and bas,ll shears overlying bedrock at depths of about 6 to 10 feet, as viewed in Test Pits TP2,20,
TP2,21. and Tp2-22. In a zone an estimated 200 feet across low on thc slope, we encountered a
deeper brown silty clay that e>;tends down to depths of about 17 to 26 feel althe locations of Test
Pits TP2,2J, TP2,24, and '1'1'2-26 and Boring 132-7. This deeper clay material is interpreted to be
an older. deeper portion of landslide deposit. In Test Pits TP2-33 and TP2-35, we encountered
what appears to be a small secondary lobe of Landslide A. Cross Sectiun /\,;\' presents our
inteqJretation of the subsurface through the intcrpreted deepest part of the Landslide A.
Landsl ide B
Landslide 13 is a possible small landslide located in about the middle of the development, on a
north-facing hillside. This possible landslide's estimated dimensions are roughly 200 by 75 feet
across. with a maximum explored depth of about III feel, at Test Pit '1'1',2. Its fonner larger
dimensions as interpreted by Nilsen (I 975) and shown in our 200 I report have been contracted,
owing to observation of relatively shallow intact bedrock in s(veraltest pits, including Test Pits
TP2,8, '1'1'2-9, TP2-10, '1'1'2-38, '1'1'2-39, and '1'1'2--10.
Downslope,dipping shears, some with moderate dip angles of 31 0 and 350, were observed within
bedrock in the area upslope in Test Pits '1'1'2-7 and '1'1'2-37. Rather than landslide related, we
interpret these shears as bedrock related, within claystone of the Tassajara Formation, as
discussed under fJedl'ock. The bedrock shearing, however, does point out an unusual weakness in
the bedrock that should receive careful geologic observation and evaluation during keyway
excavation. Cross Section 8-8' presents our interpretation of the possible landslide configuration
and of surrounding subsurface conditions.
Landslide C
Landslide C is located in the northeast corner of the development near the loe of the nol1hern
ridge. The landslide measures roughly 150 by 200 teet across with a maximum explored depth of'
about 9 feet. at Test Pit '1'1'-9. It consists ofelay that was deposited on intact bedrock.

BEDROCK
~
Fledrock of the Plio-Pliestoeene age Tassajara Formation is present at shallow depths below
slopes and ridge crests on the site. Three types of bedrock belonging to this unit \vcrc
encountered during our field investigations: sandstone, siltstone, and claystone. These rocks
were ~enerallv slightlv wcathned, friable. and moderate!v to hiuhlv fractured. The sandstone

\vas generally tIne'grained. In numerous places, we found the claystone to be eriss,crossed by
randomly oriented, intersecting, dimpled shears. These shears arc generally believed to be due to
tectonic deformation (regional folding and uplift) concentrated within thesc weak roek layers,
with a possible additional component due to swell of the expansive clay. Bedding within the
Tassajara Formmion was gener~llly found to strike to the northwest and dip about )00 to 40"
sOLlth\vesL consistent \vith published regional maps as \ycll as Our findings on nearby sites in the
vicinity. Tassajara Formation is dclincalcd bv the symbol "QTt" on the Geologic !'.'lap.
GROl:N[) WATER
Ground water was encountered in Borings D,J and B-2 at depths of about 30 and 20~.S !Cet,
respectively. in July )00]. Ground water was not encountered in any of the auger borings or test
pits excavated for this investigation. Groundwater elevation was obscured by the drilling method
at Boring B2-1. Ground water conditions at the site are expected to vary significantly depending
on weather conditions during that time of year, waltI' level in the creek and local irrigation
practice~.
CONCLUSIONS AND RECOiVIMENDATlONS
GENERAL
From a geotechnical standpoint, the devclopment can generally be constructed as planncd,
provided the conclusions and recommendations contained in this report are incorporated into the
project design and construction. This investigation was in part tailored to provide infomJation
relative to thc grading altemative as sbown on tbe Geologic Map. The conclusions and
recommendations presented hcrein may require modifIcation if a different grading concept is
proposed. The primary geotechnical issues afleeting the proposed development are presence of
expansive soils and mudstone bedrock materials, and landslides.
Other geotechnical concerns addressed in this report include [Ill settlemcnt and stability of the
creck bank.

EXPANSION POTENTIAL
As indicated by the results of the Atterberg limits and single point consolidation/swcll tests
contained in Appendix B, the expansion potential of soil and bedrock materials at the site are
highly variable, ranging from low to highly expansive. Thc dcgree of expansion of the on-site
materials is a function of the (",!lowing main L1ctors: the type of soil and bedrock materials. and
clay composition, the in-place 1110isture content and density of the materials, and the overburden
pressures or surcharge loads acting on the matcricds.
The two main expansive material types at the site include 1) expansive near-surface soil deposits
consisting of residual soils, colluvium, landslide debris and clavey alluvial soils; and 2)
mudstone bedrock units composed of siltstone and claystone.
The on,site residual soils. colluvium. landslide debris and clayey alluvial soils mc considereel
highly expansive when subject to changes in moisture content. The siltstone and claystone
~xhibit variable expansion characteristics ranging fro In 111ediun1 to high, generally varying in
expansion potential among individual beels of siltstone and claystone.
Using the results of the single-point eonsolidation/swcll testing on remolded soil and bedrock
malerials, the preliminary total swell or' the tlll placed and compacted foll<l\ving the
recommendations presented in the "Site Preparation and Grading" section is estimated as
follows:
[=. · -. 'mn:i~"''''") .~~~.. .J . .i'm""~:'''r2W:"'"~~-~3
The above-estimated preliminary swells provide a general picture of the swcll potential in the tlll
meas. The actual swell in the fill areas depends strongly on the composition (type and amount),
and in'place moisture content and density of the fill.
SETTLEMENT
The results of single-point consolidation testing on remolded soils and bedrock of the site are
summarized in Appendix B. Based on these results. we estimate that on-site materials used as
flll will undergo settlements during placcment and for a duration [allowing mass grading. The
total settlement of the fill placed and compacted in accordance with the "Site Preparation and
Grading" section are estirnated as f()llows:

In-place colluvial deposits in dcep illl arc as are stitf to hareL and exhibit low to nominal
comprcssibility characteristics. As such, provided the upper about 2 to 3 [cd of soliened soils
along swale bottoms are removed tiom these areas, we anticipate that stitT colluvium may be left
in-place in tIll arcas. The colluvi31 deposits left in-place are anticipated to undergo limited
settlements during fill plaCClnent and for a duration follc)\,ving mass gr:Jding. \\le cstilnate that in
the (!cepeI' till areas, potential settlements of the in-place colluvial material could bc on the order
01':2 to 3 inches.
Based on our experience, we anticipate that about 75 percent of the estimated total settlement of
the Jill and in-place colluvium will occur during mass grading. For a 40,foot-thick till. up to
about :2 Sf: inches of post-grading long-ternl settletnent is estimated.
The total and ditlerential settlement at the site should be considered m the design or gra\ity
underground utilities (such as storm drains and sewer lines) and surLiee drainage. The gravitv
underground utilities and surface drainage installed immediately ,lfter mass grading should be
designed to accommodate the post-grading settlement. \Ve recommend that one and one,half to
two times the estimated post-grading long,tcrm settlemcnt be incorporated in the design of the
storm drains and SC\Vcr lines.
STABILITY OF CREEK BANK
The section of the tributary to Tassc~ara Creek located within the site is a deeply incised
meandering channel with locally steep banks about 20 feet high. Sink holes likely caused by
rodent and root action, piping, and slightly dispersive soils have developed near the top of bank.
Based on the soils encountered in Boring B2,2 it is our opinion that the creck bank soils can be
highly erodible. A slope stability analysis was performed thl'Ough a typical portion of creek bank
near Boring B2-2 and the results of the analysis are presented in Appendix C. Based on this
analysis, we recommend the following:
1. A structural setback to a line where an imaginary 21-1: I V plane projects up from the base
of the creck bank; and
~
Site grading should be designed to reduce surhice \vater from f10wing over the creek ollnk
and to prevent any water ponding near the top of creek bank.

We sbould observe the tributary creek bank after the final grading plans arc prepared to

panel.
LANDSLIDE REMEDJATION
The recommended remedial treatment of each landslide depends on a number of factors
Including the relationship of the landslide to the proposed development, the tvpe and si~e of the
landslide. and individual characteristics of each landslide.

ARTIFICIAL FILL
-I
The identified fill in the vicinity of 'I' est Pit TP2-18, ifnot removed by design Cllt, should be Over
excavated and replaced with engineered fill. The till contains some organic matter and could be
placed in nonstructural areas as agreed to by the developer and the soil engineer, or may be
placed within engineered fill at a ralio of 1 part organic till to 10 or more parts clean soils
provided debris is removed.
ClIT/FILL BUILDING PADS
The upper 3 feet of bedrock exposed in cut!tlll building pads should be overexcm'aled and
replaced with engineered fill.
SITE PREPARATION AND GH.ADlNG
A.ll grading operations should be perti}Dned in accordance with the 1(Jllowing recommendations:
I. Areas to be graded should bc cleared and stripped oC significant all vegetation.
Strippings should be stockpiled and reused as topsoil. Alternatively. strippings may be
placed within engineered fill at a ratio of 1 part strippings to 10 or more parts clean soils.
~ Landslide debris should be removed in areas to receive 1ill and in areas where the
landslide debris is not entirely removed by the design cut.
3. In the central about 20 feet of s\valc areas to receive fill. the upper 1 to 3 feet of
colluvium should be removed. Where colluvial soils underlie major till slopes and the
existing ground surface is 7H: 1 V or steeper, the colluvial soils should be removed to
bedrock as shown on Plate 4.
4. Along cuUfill transition lines, the residual soils and colluvium should be removed to at
least 10 feet below finished grade and replaced with engineered fill.
5. lanes of soft or saturated soils may be encountered during excavation and compaction:
therefore, deeper excavation may be required to expose firm soil. This need for deeper
excavation in localized areas should be determined in the field by the soil engineer.
6. The exposed sLlbgrade in fill areas should be scarified to a minimum depth of 12 inches.
The scarified materials should be properly moisture,conditioncd ancI re'eompaetccI as
follows:

Relati ve compaction refers La the in-place dry density of soil expressed as a percentage of
tbe maximum dry density of tbe same soil as cktermined by the ASTill D1557,()O
compaction test metbod. Optimum moisture is the water content (percentage by drv
\veight) corresponding to the D1J.xinnul1 dry density.
7. In general, the on-site earth nlaterials arc considered acceptable for engineered fill,
provided significant surface vegetation, debris and deleterious materials are rcrnovec!.
8. Bedrock materials should be used as material for engineered fill in the following areas:
. Within 50 feet horizontally of fill slope filetS;
\I'l In kc.y\vays; and
. Upper 10 feet of the pads.
<J. All [ill and baeklill materials should be subject to evaluation by the soil engineer beiilre
LIse. Native soils are suitable tilr treneb backfill.
10. Fill should be placed in thin lifts (normally 8 to ]2 inches thick), uniformly moisture
conditioned, and compacted in accordance with the criteria presented in the table below.
\Vithin 20 feet of finished grade 85 to 90 percent relative compaction at not Jess than 5
pc:rcent above optimum moisture content.
Between 20 and 40 feet below nnished grade At least 90 percent relative compaction at 110t less than
5 percent above optimum moisture content.
At greater than 40 feet below finished grade At least 95 percent relative compaction at not less than
3 percent above optimum moisture content
To avoid over-compaction of (m-site expansive materials, care should be taken during
grading to minin1izc placernent of thin lifts of expansive materials (less th~lt1 abou1 8
inches). Modification of actual acceptable lift thicknesses should be based on
demonstrated cOlnpaction perfonnance during grading, \vhich \vill depend on actual
cornpaction equipment and rl1cthods llsed.

II. Keyway Ii!! should be compacted to at least 90 percent relative compaction at a moisture
content of not less than 3 percent above optimum moisture content.
12. Where bedrock units arc exposed in cut building pads, the exposed bedrock should be
evaluated by the project geotechnical engineer for variations of expansion potential.
Geologic mapping and laboratory testing should be performed in these areas. As deemed
appropriate, additional recommendations for over-excav<.ltion and remedial grading
should bc developed in these areas during grading following evaluation.
! 3. Fill slopes should bc overbuilt horizontally at least 2 feet and then cut back to design
grade to expose a firm and compacted surface. Alternativelv. the slope surface can be
tnlck,rolled to at least 90 percent relative compaction.
1-1. Observations and soil density tests in Ell should be perf;Jrmed during grading to assist the
contractor in obtaining the required degree of con1paction and proper 1110isturc content.
\Vherc compaction and 1110isture content arc outside our recornmcndecJ ranges, additional
eompactive effort should be made with adjustment of the moisture content as necessary
until the recommended requirements arc obtained.
! 5. The soil engineer should be notified at least 48 hours prior to any grading operation. The
procedures and methods of grading may then be discussed between the developer.
contractor, and soil engineer. Thls can Llcilitatc the pcrforn1ance of grading operations
and 111inimizc possible constructiun delays.
PI,ELlMINARY SHRINKAGE/SWELL FACTOR
Based on the laboratory compaction test results from this investigation. on,site earth material
densities as encountered in the borings. the compaction requirements outlined in the "Site
Preparation and Grading" section, and proposed grading as shown on the plans prepared by RJA,
we recommend that a swell factor of about 10 percent be considered in the preliminary dirt
quantity calculation. These values should be re-evaluated wIlen a detailed gradillg plan has been
prepared.
CUT SLOPES
We recommend that cut slopes generally be constructed at slope gradients no steeper than
31-1: 1 V, except for cut slopes less than about 10 feel in height which should be no steeper than
21l: 1 V. We recommend that all cut slope exposures be carefully cxamined by an engineering
geologist for evidence of potential instability. Where cut slopes over 3D feet high are planned.
intermediate benches spaced no greater than 25 feet vertically should be provided. Benches
should be at least 8 feet wide and have a concrete lined V -ditch along the bench to intercept
rUlloff Alternatively, cut slopes higher than 3D teet may be constructed without benches,
provicled additional erosiou control is installed on the pot1ion of the slope more than 3D feet

determined during our review of' the grading plans.
The stability of cut slopes in bedrock materials is largely dependent on the planned cut location
and the orientation of the cut slope with respect to bedrock structure or other planes of geologic
weakness. Vie recommend that all cut slopes be mapped during grading. \Vhere adverse
bedrock structure or other zones of geologic \vcakness are encountered in cut slopes during
grading, \\"t? anticipate th~t relnedial 111eaSUres such as flattening the slope or construction of a
slope butlrcss will be needed. Specific remedial alternatives should be evaluated as cut slope
conditions arc exposed during grading.
FILL SLOPES
The stabilitv of planned fill slopes depends on proper keyways and benching. subdrainage, fill
compaction, and slope gradients. We recommend that generally fill slopes exceeding vertical
heights of 10 feet be constructed at slope gradients no steeper than 31-1:1 V. If built with select
bedrock materials. fill slopes more than 10 feet high may be constmcted at gradients of 2'1,H: IV.
Fill slopes less than about 10 feet in vertical height may be constructed at slope gradients up to
2H:] V. If used for i11l slope construction, residual soils, colluvium, and landslide debris should
be properly blended with bedrock materials. In general, blending should consist ot' 1 part \Ieak
sods to J parts n1inimulll bedrock l11aterials.
Eaeh fill slope exceeding 30 feet in height should be. provided with a drainage bench placed at
midslope elevation. Benches should he at least 8 leet wide with a eonercte,lined V ditch (0
conduct runoff /\Ikrnatively. till slopes higher than 30 feet m;})' be built without benches.
provided additional erosion controlmatling is applied to the portion of the slope that is more than
about 30 feet below the top of the slope. Fill slopes should generally be constructed lollowing
the recommendations shown on Plate 4. Generally. keyway width should be at least 15 feel or
one-half of the fill slope height, whichever is greater. Properly subdrained horizontal benches
should be excavated into firm material or bedrock to key tills into the native material during
slope construction.
EROSION PROTECTION
All cut and fill slopes should be planted with deep-rooted, fast growing grasses before the first
winter to reduce erosion.

Specification (July, 20(2). Subdrain trenches should be at least 18 inches wide and at least..] fect

should be capped with engineered till or topsoil. depcnding upon the subclrain location. Typical
subdrain details are presc;nted un Plate 5. Subc1rain systen1s should be discharged into observable
storm drain structures (inlets, manholes, ditches) where possible. Elsewhere, subclrains may
discharge to suitable open-space locations.
Some areas of seepage n1ay develop aCter grading and house construction arc complc:ted.
Additional subdrains will likely be needed in these areas should seepage dcvelop.
FO!JNDA TION
Because of the long-term differential settlement and swell, it is judged that foundations for
houses should consist of structurally reinforced mat systems designed to resist potential
differential movement of the on-site expansive soils.
Structural mat toundations designed to accommodate an estimated 3 inches of differential
movement over the length of the house (estimated to be about 60 feet), without experiencing
structural distress to the mat and excessive detlections in the house ti'aming and wall finishes.
The structural mat foundations should be designed to structurally span at least 20 fect in the
interior and cantilever minimum 6 ket along the perimeter. if the slab is 13 inches or thicker,
the span and cantilever criteria can be waived. In addition to the span requirements, the
f(illo\ving criteria should be incorporated in the slab foundation design.

I, is our opinion that, from a geotechnical engineering standpoint, foundation concre1e slabs-on,
grade can be supported on prepared subgrade. During foundation installation and utility trench
cxcavation and backfilling, previously compacted sub grade soils may becomc disturbed. On,s;te
expansive materials should be uniformly moisture conditioned at least fivc percent above
optimum and re-rolled to provide a smooth and unyielding surface compacted to 85 to 90 percent
relative compaction.
Prior to concrete slab placcment, the soil engineer should check that thc upper 18 inches of
expansive soils benealh the slab have a moisture content at least 7 percent above optimum. If the
expansive soil is drier than reC0J11111t'ndcd, the c.'\-pansivc soil should be soaked until it meets the
required moisture content.
Where movement oC moisture vapors through the slab would be objectionable, a capillary
moisture break and vapor retarder should be considered by the designer of the slab. The
thicknesses of the capillary moisture hreak and vapor retarder should be determined by the slab
designer.
CONCRETE SLABS-ON-GR./\,DE
Exterior concrete work placed upon on,site expansive materials could also be subject to
movement due to soil expansion. From a cost-benefit standpoint, the exterior concrete work
subgrades in areas of expansive soils should be moisture conditioned to at least 7 percent above
optimum moisture content to a depth of at least 12 inches to promote some soil expansion and
compacted to 85 to 90 percent relative compaction prior to placement of concrete, thus reducing
the amount of post-construction soi I expansion. The prepar'cd subgrade should be kcpt llloist and
shouJcI not he allowed to dry below the recommended moisture content. Once moisture
conditioned. exterior concrete work sub grade sbould not be subject 10 heavy equipment
construction trame, because it could be over compacted by these vehicies.

UTILITY TRENCHES
All excavations should conl'orm to applicable state and Cedcral industrial safdy requirements.
Where trench excavations are more than 5 fed deep, they should be sloped and/or shored.
Trench walls should be sloped no steeper than 1 y,II:IV in dry granular soils, and no steeper than
I II: I V in dry. cohesive soils. Flatter trench slopes may be required if seepage is encountered
during construction or if exposeel soil conditions difkr from those encountered by the test
borings. If full,sloped trench walls cannot be excavated due to site constraints, shoring should
be provided to ensure tn~nch stability and safety.. We can provide sod parameters for shoring
design on request.
lvlalerial quality. placement procedures. and compaction operations for utility line bedding and
shading materials should meet the City of Dublin or utility agency requirements. Utility trench
backilll above the shading materials may consist of native soils processed to remove rubble, rock
fragments over 8 inches in largest dimension, rubbish, vegetation and other undesirable
subslclnccs. ()n,site expansive backfill materials should be placed in level lilts about 8 to 12
inches in loose thickness, brought to at least 5 percent over optimum moisture content. and
mechanically compacted to between 85 and 90 percent relative compaction at depths below 30
inches of' Ilnished grade and at least 90 percent relative compaction above JO inches from finish
grade L.o\V expansive baektill materials should be placed in lifts not exceeding 8 inches in loose
thickness, brought to over optill1LUll moisture content, and compacted to not less than 90 percent
relative COl1llxlction. No jetting is permissible on this project.
Depending Oil time of year, rainfall and local iiTigalion practice, ground \v-ater could be
intercepted during trench excavation, in which case dewatering is likely to be requircd.
RETAINING WALLS
Cantilever concrete or masonry retaining vvalls can be supported on footing foundations founded
on engineered fill or f1rm native soils or bedrock. We recommend that the following
geotechnical criteria be incorporated in the retaining wall design:

The above recommended lateral pressures are based on drained condition and do not include any
surcharges. Therefore, the designer should include the appropriate surcharge loads to the

To prevent hydrostatic pressure build-up, the retaining walls should be provided with permanent
backdrains. The backdrain should consist of a blanket of Class 2 permeable materi21
(conforming to Section 68.1025 of the State of California Standard Specifications, dated July,
2(02) and a 4,inch diameter perforated rvc pipe (SDR 35). The permeable material blanket
should be at least 12 inches thick and should be placed from the base of the retaining wall to
about I foot below the Ilnished grade of the top of the rctaining wall. The perforated pipe should
be placed near the bottom of the wall to carry collected water to a suitable gravity discharge.
PRELIIVliNARY PA VEl\IF:NT SECTIONS
The following recommendations for preliminary asphalt concrete pavement sections are intended
as a conceptual guide for planning only. Pavement analyses are based upon an assumed
resistance (R),value of 5, which we expect to be representative of tlnal pavement subgrade
materials, the Caltrans "Design Method for Flexible Pavement," and traftle indices (TIs) which
are indications of load frequency and intensity. We have assumed that the assigned TIs include
provisions for heavy truck traffic related to construction activities. We recommend the following
preliminary pavement sections.

Since this is a relatively large grading project and the on-site material propetiies vary fi'om
sandstonc to clayey materials, we recommend that samples be obtaincd from the rough roadway
subgrades after mass grading. R- Value test should bc pertonned on these samples. Final
pavement seclion recommendations should be made on the basis of these test results.
Prior to subgrade preparation, all utility trench backfill should be properly placed and
compacted. Subgrade soils should be rolled to at least 95 percent relative compaction to provide
a smooth, iJnvielding surface. Subgrade soils should be maintained in a moist and compacted
condition until covered \vith thc complete pavement section.
Class 2 aggregate base should conform to thc requirements in Section 26, Caltrans "Standard
Specifications", (July, 2002). The aggregate base should be placed in thin lifts in a manner to
prevent segregation, uniformly moisture conditioned, and compacted to at leaot 95 percent
relative compaction to provide a smooth, lJ.l1vi~ldiJ.1g surface. (Relative compaction refers to the
in'place dry density 01' soil e"pressed as a percentage of the rml"imum dry density of the same
soil. as determined by the ASTlvl 01557,00 compaction test method).
'1'0 prevent the subgrade soils and aggregate base from saturating hy irrigation \-vater or infiltrated
rain water. we recommend that roadway underdrains be installed at the bottom of the aggregate
at the edge of pavemcnt, as shOlvn on Plate 6.
\Vhcre drop inlets or other slIrLlce drainage slrllclures are to be installed, slots or, \veep holes
should be provided to allow free drainagc oCthe contiguous basc eoursc materials.
CORHOSION CONSIDERATiONS
The results of our preliminary corrosivity testing along with a bricf evaluation arc prescnted in
Appendi" D. We recommcnd a corrosion expert be consulted regarding the results of the
preliminary testing and for additional recommendations for final corrosion design.
SEISMIC HAZARDS
FAULTING
The site is located outside designated State of California earthquake fault zones (Davis] 982) for
active faults, and no evidencc of active or potentially active faulting was found on the site. The
potential for fault rupture at the site appears to be low.
GROUND SHAKING
The site is located in a region of' high seismicity given the proximity of' the Calaveras fault and
other acti\'c hmlt systems in the San Francisco Bay Area. As for all sites in the Bay Area, the
project can be expected to experience at lC3st one lrtodcra1e to SC'lcre earthquake during the life
SIXln of the project. Ground shaking is a ha~ard th::lt cannot be din1lnalcd bul can be partially

mitigated through proper attention to seismic structural design and observance oC good
construction practices.
According to the 200t California Building Code (CBC), the fllllowing geotechnical input can be
used in the structural design of the new foundations and structures:
g~:g;'~~';M" ~=:'m,,~~~=,"")l. ...... .,t, ..
'~--- . ~--
It is Ollr opinion that tbe structural integrity of the proposed buildings is a prinlary Elctor in
determining potential SCiSI11ic danlagc and that the degree of seismic di.lI11agc would only be
nominally inlluenced by the foundation system selected. We recommend that, at a minimnm, the
buildings be designed in conformance with the current edition of the CBe.
LIQUEFACTION
Liquefaction is the temporary trans!lmnation of a saturated, cohesionless soil into a viscous
liquid during strong ground shaking fro 111 a 111:ljor earthquake. There is no evidence of historic
ground failure due to liquefactiCHl on the site, nor did \ve encountered any earth materials \vhich
might be susceptible to liquefaction. Therctclre, the risk DC jiqucLrction is believed to be low.
LURCHING
Lurching is the sudden swaying, spreading or rolling of the ground during a strong earthquake.
Lurching usually is accompanied by the development of fissures on slopes overlain by weak
soils. Grading in conformance with the rccommendations presented in this report should reduce
the risk of lurching to low.
GROUND SUBSIDENCE
Ground subsidence can occur as a result of "shakedown" when dry, cohesionless soils are
subjected to earthquake vibrations of high amplitude. The loose cohesionless soil condition is
not present at the site; therefore, seismic indoced gronnd subsidence is not considered a geologic
hazard on the properiy.

EARTHQUAKE,lNDUCED LANDSLlDING
Strong ground shaking during a major earthquake is likely to cause reactivation of landslides in
many parts of the bay area. The stability of all slopes is lower during earthquake disturbances
than at other times. Grading in accordance with the recommendations in this report should
reduce the risk of seismically induced landslides within the development area to low.
ADDITIONAL SOIL ENGINEI~RING SERVICES
Prior to construction, our firm should be prnvided the opportunity (0 review the plans and
speeitlcations to determine if the recommendationsoC this report have been implcmented in
those documents.
To a degree, the performance of the proposed development is dC[1endent on the procedurcs and
quality of the construction. Therefore, we should provide on-site observations of the contractor's
procedures and the exposed soil bedrock conditions, together with field and laboratory testing
during site preparation and grading, landslide remediation, retaining wall construction.
underground utility installation~ hOLlse foundation construction and pavC'lllcnt construction.
These observations will allow us to check the contractor's work for conformance with the intent
of our recommendations and to observe unanticipated soil conditions that could require
modification of our recommendations. In addition, we would appreciate the opportunity to meet
with the contractor prior to the start of construction tn discuss the procedures and methods. This
can facilitate the performance of the construction operation and minimize possible
misunderstandings and construction de!J.ys.
LIMITATIONS
The conclusions and recommendations nf this report arc based upon the information provided to
LIS regarding the proposed improvements, subsurface conditions encountered in test pits and
borings, our geologic recolmaissance, the results nf the laboratory testing program, and
professional judgment. This study has been conducted in accordance with current professional
geotechnical engineering and engineering geologic standards; no other v,:alTanty is expressed or
implied.
The locations of the test pits and borings were determined by taping, estimating, or pacing trom
established cultural and natural features and other points of reference indicated on the drawing
supplied by RJ/\, and are to be considered approximate only. The elevations of the borings and
nther elevations discussed in the text of this report were determined by interpolation between
nearest adjacent ground surface contolU'S shown on topographic maps supplied by RJA. and are
also to be considered approximate only. Site conditions described in the text arc those existing at
the time of our last field exploration and reconnaissance during August of 2003, and are not
necessarily representative of such conditions at other locations and tirnes.

Corrosivity Analysis - ASTM Test Methods
1)(':11" .Vlr. ~~tcp)lcn~::
Pursuant to your request, CERCO Analytical has ~lI1alYlcd the soil samples submitted on August 07. 2003.
Based 011 the <lllalJ'tical results, a brief corrosivity evaluation is cnclosed for }'our COllS1lkration.
Based upon the resistivity measurcments, hoth samples are classified as "corrosive". /-\11 buried iron. steel,
cast iron, ductile iron, galvanized steel and dielectric coated steel or iron should be properly protected against
corrosion depending upon the critical nahJrc of the structure. /\]) buried metallic pressure piping such as
ductile iron firewater pipelines should be protected against corrosion.
The chloride ion concentrations range from 34 to ] 40 mg/kg. Because: the chloride ion concentrJtions ~l1"e
less than 300 mg/kg, they arc determined to be insufficient to Jtt~lck steel embedded in a concrete mortar
coatll1g.
The sult:1te ion conccntrations range from 60 to 980 mg/kg and arc determined to be sufficil'J1t to damage
reinforced concrete structures and cement mortar-coated steel at these locations. Therefore, concrete that
comes into contact with this soil should use slllfate resistant cement such as Type 11, with a maximum water-
to-cement ratio of 0.50.
The pH of the soils range from 7.6 to 8.8 \vhich docs not present corrosion problems for buried iron, steel,
mortar-coated steel and reinCorced concrete structures.
The redox potentials range ii-om 370 to 470-mV. Sample No.002 is indicative of potentially "slightly
corrosive" soils resulting from anaerobic soil conditions, and Sample No.OOl is indicative of aerobic soil
conditions.
This corrosivity evaluation is based on general corrosion engineering standards and is non-specific in nature.
For specific long-tern1 cOlTosion control design recommendations or consultation, please call JDH Corrosion
Consultants, Inc. at (925) 927-6630.
