~~Adopt Resolution .
The co~t of the study is not to exceed
$15,872. The amount of $10,000 is budgeted
in the line item for soils testing in the San
Ramon Road Improvement Phase IV Capital
Improvements Project (CIP) for this purpose.
There are sufficient total funds budgeted for
1991-92 to cover the increase in this line
item. These funds are to be paid from State
Gas Tax subventions.
DESCRIPTION: Included within the San Ramon Road Phase IV
Capital Improvement Project is a geotechnical and soils investigation
to determine the soil stability of the western hillside of San Ramon
Road.
The soil on the western hillside of San Ramon Road, between Vomac Road
and Alcosta Boulevard shows possible signs of previous instability,
and it is suspected that the Calaveras Fault also traverses this area.
There has been a long-term plan to landscape the western slope of
San Ramon Road within the public right-of-way, if feasible. A
geotechnical and soils investigation needs to be performed to
determine (1) if this hillside will be stable in an earthquake on the
Calaveras Fault for the safety of the residents above the slope and of
the road below; (2) whether this slope will remain stable if irrigated
or if an earthquake occurs, and the cause of any instability resulting
in slope movement; and (3) to recommend mitigation measures, if
needed, to improve stability.
The Public Works Department received three (3) proposals from local
qualified engineering consulting firms. After reviewing all three
proposals for past performance, experience, knowledge of the area,
ability to complete the project in a timely manner, and equipment and
staffing, Staff considered Earth Systems Consultants (ESC) as best
able to fulfill the City's requirements.
After selecting Earth Systems Consultants, Staff opened the fee
proposal package and found ESC's fees to be in line with the scope
of work to be performed. In accordance with State law, selection of
engineers and architects must be based upon qualifications, rather
than bid price.
Staff recommends that the City Council adopt the Resolution approving
the Agreement with Earth Systems Consultants.

REVISIONS TO PROPOSAL AND FEE ESTIMATE
FOR GEOTECHNICAL INVESTIGATION
Gentlemen:
Earth Systems Consultants previously submitted a Proposal For Geotechn/cal Investigation and a
Fee Estimate for Geotechnical Investigation for the subject project, located in Dublin,
California. Both documents were dated September 18, 1991. At our negotiations meeting on
October 30, 1991, you requested that we consider reducing our scope of work on the project in
order to reduce our total estimated fee of $19,517.00.
Based on our discussions with you and our review of available geotechnical and geologic data
contained in the provided reports and maps, we present the following revisions to our scope of
work and the revised estimated fees.
The subsurface exploration described in Item (4)of the Proposed Work Program in our
proposal was based on analyzing three cross-sections of the slope. Instead we will analyze only
two cross-sections thereby reducing the number of required soil borings from six to four. This
reduction in scope was possible since the northern area of the site is privately owned.
Therefore, the estimated fee for Task II (a) will be reduced from $5,606.00 to $3,366.00.
The laboratory testing program described in Item (6) of the Proposed Work Program in our
proposal will be reduced accordingly because there will be less sampling. Therefore, the
estimated fee for Task III will be reduced from $2,920.00 to $2,100.00.
We have also reduced the length of the meeting associated with Item (1) of the Proposed Work
Program in our proposal from three hours to two hours, and the number of representatives
from our firm attending the meet!rig from three to two. Therefore, t. he estimated fee for Task I
will be reduced from $2,420.00 to $1,745.00.
PP-101 (Revised)
November 4, 1991
The revised estimated fees associated with each task are as follows:
Original
Task Description ~
Meet with City's representatives to review

$19,517.00 $15,782.00
As stated in our September 18, 1991 fee estimate letter, the above estimated fees are based on
the hourly rates and unit prices listed on the enclosed Fee Schedule (5/90), and is valid
through the end of 1991. We will notify you immediately if there are any changed field
conditions that would result in a substantial change from the above revised estimate. The
foregoing estimate does not include any services that may be required after submittal of the
report.
?P-101 (Revised)

If the above revised scope of work and estimated fees are satisfactory, and you wish us to
proceed with the geotechnical services described above, please submit the appropriate contract
documents for our review and signature.

South of Alcosta Boulevard
Dublin, California
INTRODUCTION
Based on the information provided with the Request for Proposal (RFP), it is our understanding
that the City of Dublin plans to landscape the western slope of San Ramon Road, located between
Vomac Road and just south of AIcosta Boulevard. The location of the slope is shown on the
attached Figure 1, which was reproduced from the figure attached to the RFP. A geotechnical
study is required to evaluate the stability of the subject slope and whether landscaping of the
slope is feasible. If the slope is determined to be unstable, recommendations are required for
mitigative measures for stabilization. If the slope is stable, then a study is required to evaluate
if landscaping irrigation will tend to destabilize the slope. If so, then recommendations for
mitigation measures are required to develop a stable slope.
As we understand the project, the City of Dublin has two main concerns: 1) the long-term
stability of the slope; and 2) whether the slope is impacted by an active fault.
Earth Systems Con~,ultants Northern California (ESC) is in an excellent position to provide the
requested geologic and geotechnical information. ESC previously mapped the Calaveras Fault
south of the proposed site, in Shannon Park, while working on the Southgate Subdivision, and we
recommended the setback zone in use today. In a study done by ESC at Laborers Camp, just north
of the Alameda County line, no evidence of the fault was found. We have also done geologic studies
for The Springs (old Hansen Ranch) and the Dublin Ice Rink. On these projects an active fault
was located and a set back zone was established. This zone has been utilized to position the
PP-101
September 18, 1991
various structures along San Ramon Road. These reports were reviewed and approved by Dave
Carpenter, the County Geologist at that time. These reForts are on file with the County and at
our offices.
Earth Systems Consultants has various types and scales of stereo aerial photographs on file that
date from 1948 to the present. Many of the photos were specifically flown under contract to
ESC. The types of photos include large and small scale black and white, black and white Iow sun
angle, infrared, false color infrared and color. These photos will be used in this study.
The position of the "Calaveras Fault" as it relates to this site is presently in question. At a
recent Geological Society of America Convention held in San Francisco in February 1991, three
papers (USGS fault studies) indicated that the activity of the Calaveras Fault may transfer to the
Hayward Fault at Sunol (south of Dublin). The Special Studies Map (CDMG, 1982) shows the
position of the fault along the western property line, where as in 1974 the previous special
studies zone map showed the fault in the valley. The USGS (1976) shows the fault as stopping at
the county line north of this site. The fault is placed in the valley east of the site. Numerous
other publications, including oil company studies, have various locations for the fault. There is
no agreement in the literature as to the location of the fault in this part of Dublin.
Prior to the formation of the City of Dublin the site specific geologic repods were reviewed by
the engineering geologist for Alameda County. The position of the fault from the studies he
reviewed placed the fault as trending toward the valley south of Shannon Avenue. It is our
opinion, therefore, that a seismic survey should be performed on the site rather than a
trenching study for several reasons: a) to verify that the fault is not located on site; b) trench
backfill on the slope~:face would probably wash out in a future heavy rain; and c) trenches on the
top of the hill could allow water to penetrate the upper slope, potentially decreasing the
stability of the slope.
Our proposed seismic survey, along with our boring program, should give us sufficient
information to model the slope for stability. The soil characteristics will govern the stability of
the slope rather than the geologic bedding. As pointed out by Dorothy Radbruch, 1964,
landslides in the Orinda formation occur as often across the bedding planes as with the bedding
PP-101
September 18, 1991
planes. She also pointed out that north-facing slopes failed much more often than south-facing
slopes, since the north-facing slopes accumulated more water and could not dry out due to a lack
of sunlight. Therefore, our study will include analyzing the subject east-facing slope and
whether the added irrigation and lack of afternoon sunlight could decrease the stability of the
slope.
Pro.Dosed Work Program
We propose the following items of work to provide the required geotechnical information for
this project.
1 ) Meet with representatives of the City of Dublin to review the proposed scope of
work, fees and tentative completion dates.
2)
Perform a site reconnaissance. The site will be checked for surface soil
conditions and geologic features, equipment accessibility and other visible
features, such as fill, debris and vegetation.
3)
Gather, review and evaluate existing geotechnical reports, construction
drawings, aerial photographs, topographic maps, and other pertinent documents.
This item will include a stereoscopic analysis of aerial photographs from Earth
Systems Consultants files dating back to 1948. We will also review the
geotechnical data contained in the soils report for the adjacent subdivision from
the City and County files files. We anticipate that the City of Dublin will provide
us with a topographic map of the slope.
4)
Subsurface exploration. This item will include the planning and implementation
of a drilling and sampling program to evaluate the subsudace conditions in the
proposed landscaping area. A series of five (5) to six (6) borings, ranging in
depth from 20 to 35 feet, will be drilled at selected locations on the slope
determined from our review of existing maps, reports and aerial photographs.
Representative undisturbed and bulk samples will be collected from the borings
and returned to our laboratory for testing. Local drilling contractors will be
used as subcontractors to provide drilling and sampling equipment. We
anticipate that track-mounted drilling equipment will be required due to the
PP-101

5)
6)
steepness of the existing terrain. Logging and sample retrieval will be done by
representatives of Earth Systems Consultants. During sample retrieval,
Standard Penetration Tests (SPT) and pocket penetrometer tests will be
performed.
Geophysical testing. A seismic survey will be performed on the site to help
identify potential faulting on the site and to aid in determination of the strength
characteristics of the soils.
Laboratory testing program. This item will include planning and implementation
of a laboratory testing program to determine the relevant engineering
characteristics of the sampled subsurface materials required for slope stability
analysis. The laboratory testing program will include: in-situ moisture content
and dry density determinations, direct shear and unconfined compression tests in
order to determine the strength parameters of the encountered materials; and
Atterberg Limits and hydrometer tests to aid in soil characterization.
7)
Analysis and evaluation of data. After completion of the exploration and
laboratory testing program, we will evaluate the gathered data and perform the
necessary slope stability analysis. The slope stability analysis will be
performed with the aid of TSLOPE and TSTAB computer programs. The slope will
be analyzed for both static and dynamic conditions, utilizing the seismic
parameters provided by our geological staff.
8 ) Discussion of findings with City Officials. After we analyze the data we will meet
with the City,of Dublin Public Works staff to discuss the findings.
)Preparation of a written report with the appropriate graphics which will
present the findings of our study and will include the following:
a. The exact location of the Calaveras Fault in relation to the subject site if
determinable;
b. The soil stability of the existing hillside. If the slope is determined to be
unstable, recommendations will be provided for mitigative measures to
stabilize the slope;

REQUEST FOR PROPOSAL (R.F.P.)
GEOTECHNICAL AND SOILS INVESTIGATION
OF THE WESTERN HILLSIDE OF SAN RAMON ROAD
The City of Dublin invites Submittals of Proposals to perform and
prepare reports for geotechnical and soils investigation to determine
soil stability of the western hillside of San Ramon Road and if the
landscaping in the area is feasible. If the western slope is
determined unstable, recommend mitigation for stabilization.
~ackqround
The soil on the western hillside of San Ramon Road, between Vomac Road
and south of Alcosta Boulevard, shows signs of previous instability.
It is suspected that the Calaveras Fault also traverses this area.
Spring waters have been found exiting the slope.
The City of Dublin plans to landscape the western slope of San Ramon
Road within the public right-of-way, if feasible. A geotechnical and
soils investigation needs to be performed to determine if the soil is
stable, the cause of any instability resulting in slope movement, and
recommend mitigation measures to improve stability.
If the slope is stable or can be made stable, a determination needs to
be made whether landscaping with irrigation will promote instability,
and if so, what steps should be taken to prevent this from occurring.
Scope of Work
The Consultant's work scope shall include the tasks outlined below:
TASK I. Perform a site reconnaissance and review existing geotech-
nical reports, construction drawings, aerial photographs,
