Subject: Terminal Reservoir Number 2 Replacement Contract Amendment No. 2,
Additional Geotechnical Investigation for Landslide Delineation
CDM Project No.20515-35977
Dear Mr. Salgado:
As you are aware,CDM is providing professional services to the City of San Juan Capistrano
(City) under the Personal Services Agreement dated April 2,2002 between the Capistrano
Valley Water District and Camp Dresser&McKee,Inc. for the Terminal Reservoir No. 1
(TR#1) Replacement Project.
During our October 41b project status meeting,the City requested that CDM prepare a scope
of services and cost estimate (Amendment No. 2) to conduct additional geotechnical and
biological field investigation and engineering analysis to assess the geologic conditions and
site mitigation schemes at Terminal Reservoir No.3 (TR#3) and existing TR#2. Results from
our geotechnical exploration indicate the presence of landslides along the east and west
canyon slopes. However,the geometry and limits of these structures are poorly constrained
and thus limit our ability to provide an effective design solution. To adequately delineate the
landslide limits,provide adequate design recommendations, additional field exploration,
laboratory testing,and engineering evaluation will be required. The following sections
present CDM's proposed scope of work and our cost estimate is summarized in Table 1
(attached). Figure 1 (attached) indicates the proposed exploration locations.
Task 1 - Project Management and Communication
Project management activities including project tracking, scheduling,subcontractor
coordination,financial management, and general project management,communications and
coordination needed to complete the additional geotechnical investigation effort as outlined
below. It is anticipated that these geotechnical services will take about 6 weeks to perform
and the project schedule will be extended for this amount of time. In order to minimize the

additional project management effort during this period,project schedule updates for the
remainder of the design effort will be provided when significant revisions are required.
Task 2—Additional Geotechnical Borings for Landslide Delineation
Conduct additional geotechnical investigations to evaluate identified failures along the
canyon slopes. In all,CDM plans to conduct six bucket auger borings, depth totaling
approximately 460 feet. All boreholes will be down-hole logged and sampled consistent with
our initial investigation. Considering that the site contains areas of sensitive habitat, two
mobilizations will be discussed below. The proposed geotechnical investigation consists of
the following tasks.
East Slope Landslide Evaluation:
• Meet onsite with City/driller/dozer to confirm exploration locations proposed by
CDM and verify access
• Use small dozer to construct access road for drill sites.
• Drill two 80-foot bucket auger borings using a limited access drill rig with boring
locations below the upper V-ditch.
• Drill one 40-foot bucket auger boring on east side of TR#2 to establish limits of east
slope landslide.
• Down hole log each boring.
West Slope Landslide Evaluation:
• Meet onsite with City/driller/dozer to confirm exploration locations proposed by
CDM and verify access.
• Use small dozer to construct access road for drill sites,if needed.
• Drill two 100-foot bucket auger borings using standard drill rig within existing horse
trail (City to verify this method suitable).
• Drill one 60-foot boring along project northern limits of landslide (approximately 80
feet upstream from concrete culvert).
• Down hole log each boring.
Please note that the City of San Juan Capistrano needs to verify that the use of the existing
horse trail as a drill pad is acceptable prior to starting the investigation.
Erosion Protection—East Canyon Slope
Soil excavated along for the east slope access road and drill pad will be replaced using a small
bulldozer. Following replacement of the soil,up to 10,000 ftz of erosion control blankets (jute
mats)will be installed and secured over the newly exposed soil surface from the access road

construction to reduce erosion during the upcoming rainy season. Note that the installation
of erosion control blankets does not include soil compaction and testing.
Task 3—Additional Biological Assessment
Conduct additional biological assessment/vegetation mapping report of west slope beyond
the City of San Juan Capistrano Terminal Reservoir property line up to the ridgeline in case
grading in this area is required for the project.
Task 4— Laboratory Testing
Conduct additional laboratory testing to evaluate material index such as Atterberg limits,
grain size distribution, expansion index,and engineering characteristics such as,
consolidation,compaction, and shear strength properties.
Task 5—Additional Engineering Analysis and Design
The scope of the geotechnical investigation since CDM's scope of work dated March 8, 2002
has changed primarily due to the newly discovered westerly landslide and the significantly
larger landslide on the easterly slope of the site. The two landslides present more complex
geotechnical conditions than previously anticipated in CDM's March 8,2002 Scope of Work.
CDM's initial geotechnical investigation (contained in our March 8,2002 scope)was
developed using the available data and was designed to evaluate the following general
design areas:
• East slope-presence of landslide beneath residential property and TR#1,
• West slope—determine the condition of bedrock and geologic structure(i.e.,
orientation of bedding and joints that may impact temporary cut slopes and final
design,
• General geologic conditions adjacent to TR#1 to support the design of replacement
TR#3 at TR#1 site, and
• General site characterization including condition and depth of existing fill,
alluvium and bedrock materials.
Amendment No. 1 included installation of the equipment for monitoring deformation at
TR#2 and additional effort for coordinating the sensitive habitat issues associated with the
proposed geotechnical program in our March 8,2002 scope.
Results from CDM's investigation to date indicate the following issues will impact design of
TR#3 and continued long-term operation of TR#2.

• East Slope
o The results from BA-1,BA-2, and T-1,indicate that the east slope landslide
is much larger than anticipated. This structure not only impacts the design
of TR#3 but may also contribute to the ongoing deformation at TR#2.
o The additional borings proposed along the east side of the site will provide
required information to more accurately constrain the landslide depth and
horizontal limits.This data is required to perform design analysis and to
prepare remedial grading design and recommendations. Without this
additional information, the design of remedial grading approaches will be
negatively impacted because of the adjacent residential property and
potential for landslide beneath TR#2.
• West Slope
o The results from BA-3,T-6, and mapping in the lower drainage channel
indicate that the west slope contains a landslide.The available data does
allow for confident delineation. In addition,based on interpretation of
geomorphic features (surface landform),the west landslide may extend
beyond the location of TR#1 and well south of TR#2.
o The additional borings for this area will provide subsurface information to
define the north limit of the west landslide.
• North Fill Embankment Slope
o Investigation of this area was not permitted because of sensitive habitat, as
a result there is no information on the subsurface conditions,which may
include landslide debris,left in-place alluvium/weathered bedrock,and
poor quality fills.
o The boring recommended for this area will provide subsurface information
to define the north limit of the west landslide.
Field mapping in all three areas will support the interpretation of landslides for both
east and west slopes.
The need for additional data analysis and reporting arises from the addition of field and lab
data that will require analysis,interpretation, and incorporation into the project design and
report. These activities will result in the additional tabulation of data,boring log and cross
section development,iterative stability analysis including shear key and buttress design,and
presentation in the geotechnical report. Based on the newly discovered site conditions,
namely the identification of complex landslide structures,the effort needed to provide the

District with an adequate design and cost effective solution to address the landslides greatly
exceeds the initial geotechnical assumptions used to prepare the March 8,2002 scope of work.
Upon receipt and review of the new geotechnical data,CDM will conduct additional
engineering analysis to provide design based on available data.This task includes the
following:
• Revise/develop cross-sections for stability analysis.
• Perform additional stability calculations.
• Design stabilization solutions (e.g.buttress shear key and back cut calculations,
design, tie-back systems,soil reinforcement, etc).
• Incorporate stabilization into final design and report elements.
Following the completion of the additional geotechnical investigation,CDM will meet with
the District to review alternatives for landslide stabilization, stabilization of Terminal
Reservoir No. 2, and location and stabilization of the proposed site of Terminal Reservoir No.
3.
Task 6—Additional Report Preparation
Compile newly generated geotechnical data, analysis,and findings into design report and
specifications.
Task 7—Meetings
CDM will not increase the number of project status meetings in the scope of work.The
remaining project status meetings will be spread out over the remaining design schedule. The
geotechnical engineers will attend up to two additional project status meetings (4 hours each)
with San Juan Capistrano representatives to present investigation results and review
proposed design.
Task 8 - Quality Assurance/Quality Control
Provide Quality Assurance and Quality Control per CDM standard Quality Management
Process protocols.
Attached,please find a copy of the proposed cost spreadsheet the details the costs shown
herein. CDM proposes to complete the tasks and scope of work defined above for a cost of
$92,854.40.
