Proposal No. 5 1 -YP7- 147
Mr. Galen N. Peterson, Consulting Project Manager
City of Carlsbad Engineering Department
2075 Las Palmas Drive
Carlsbad, California 92009-4589
Subject: Geotechnicai Proposal for Park Drive Sloughing/Drainage Study
Carlsbad, California
Dear Mr. Peterson:
Kleinfelder is pleased to present this proposal for performing a geotechnical study to provid
recommendations for the soil sloughing and drainage problems along Park Drive in the City c
Carlsbad, California. This proposal is based on our review of your letter of July 9, 1997 whic
requested this proposal and described the general problems, problem area. and anticipate
contents of the proposal. The following sections describe OUT understanding of the propose
project, scope of Kleinfelder services, our approach to the project plan, personnel to be assigne
the project, schedule, our current workload, and fees. We have also included our curre1
Standard Form 254.
PROJECT DESCRIPTION
Based on our preliminary site visit of July 15,1997, it is obvious that about 500 feet of the ea:
side of Park Drive just north of Marina Drive is experiencing some drainage and soil sloughin
problems. Water reportedly continuously percolates through the lower portion of the slope, an
we observed draining and ponded water during our recent site visit. Cattails and bamboo tend I
confirrn that the areas are probably continuously wet. The drainage for the existing retainic
walls is primarily through open joints in the face of the wall which allow drainage and soil I
accumulate on the sidewalk area. The existing pipe drain collections system appears inadequa
and simply conducts the water through the sidewalk area where it tends to collect on the stree
owing to the flat grade of Park Drive in the study area.
It also appears obvious that the lower 25 to 40 feet of the west facing sandstone bluff
experiencing typical bluff erosion similar to sea cliffs adjacent to the Pacific Ocea
Accumulations of erosion material at the base of the bluff are apparently washing further dov
the lower section of the bluff, over the existing retaining walls, and are being deposited on tl

sidewalk and street. Based on our preliminary site visit, we did not note any conditions whicl
could indicate that the gross stability of the bluff was being impacted other than the continuou
erosion and occasional surface related sloughing as portions of the bluff are undernlined b
erosion.
Two pipelines are visible along the slope above the sidewalk area which are being uncovered b:
erosion and could potentially be impacted in the near future.
KLEINFELDER APPROACH TO THE PROBLEMS
Based on our site visit and the request for proposal of July 9, 1997, we coasider that two primar:
problems are present, namely:
A. Drainage of the lower slope, and
B. Evaluating the erosion of the bluff. Also included in the erosion problem are the subse
problems of how to mitigate the erosion and how to reduce the eroded sedimer
transportation to the sidewalk and street areas.
The most likely approach to the drainage is to add additional drainage and low retaining wall;
The walls may also reduce the amount of sediment reaching the street during storm period?
Portions of the existing walls may need to be replaced to provide a better drainage system. W
anticipate that all drainage will be collected at the upper subsurface with a drainage collectio
trench and carried to a suitable underground sewer.
For the erosion and sediment, we anticipate that we will need to complete a geologi
reconnaissance of the bluff to evaluate the effects of erosion and to provide recommendations fc
potential measures. At this time we anticipate that some type of aesthetically acceptable storag
method will be required that will accommodate temporary storage and periodic removal c
accumulated sediment. We do not foresee that increasing the height of existing retaining walls c
alteration of the bluff face will be either practical, economical, or acceptable to the City Park
and Recreation Commission.
SCOPE OF SERVICES
The scope of Kleinfelder’s service will be to complete a geologic evaluation of the bluff and
limited geotechnical study at the bIuff toe to evaluate foundations design parameters for ne
retaining walls and a subdrain system. The specific tasks to be completed include:

the frequency of sediment clean-up and a representative from the Parks and Recreation
Commission should also be present. We have budgeted for a two hour meeting to discuss the
project, Kleinfelder’s scope, and to transfer additional knowledge and information the City may
have.
Task 2: Geologic Slope Reconnaissance
Our senior engineer and engineering geologist will visit the site to map the local geology of the
affected bluff face area. We will then prepare a report which will consider, describe. and analyze
the following:
1) cliff geometry and site topography, extending the reconnaissance work beyond the site as
2) current and foreseeable cliff erosion;
3) geologic conditions, including soil, sediment and rock types and characteristics in addition to
4) evidence of past or potential landsIide conditions;
5) impact of construction activity for the addition of retaining walls and drainage trenchs on the
6) ground and surface water conditions and variations;
7) potential erodibility of site and potential measures to be used to mitigate erosion;
8) Preliminary evaluation of factor of safety against deep seated circular failure using estimates
for soil strength parameters and other geologic conditions. We will aiso compute a pseudo-
static slope stability factor of safety using a seismic component of 0.1 5s to evaluate the
earthquake effects on the slope stability.
needed to depict unusual geomorphic conditions that might affect the site;
structural features, such as bedding, joints, and faults;
stability of the study area;
At the geologic slope reconnaissance level, the conclusions will not be long and detailed. The
observed conditions will be stated, and a general overview of the site geology as it correlates to
the stability of the existing bluff will be presented. An assessment of the degree of slope stability
and erosion hazards present, based on exiting information. will be given. If there are suspected
geologic problems that cannot be evaluated except through in-depth investigations, then this will
be clearly stated in the report. Since the evaluation of the factor of safety of the slope will be
based on assumed parameters, this evaluation should only be considered preliminary in nature.
Please note that if the geological reconnaissance report recommends further investigation, the
recommended investigation is not a part of this current scope.
Five copies of the draft report and fifteen copies of the final report will be provided.

Task 3: Geotechnical Investigation of the Bluff Toe
The purpose of our geotechnical investigation will be to explore the immediate foundation areas
in the vicinity of the proposed retaining walls to provide recommendations for the design of the
retaining walls, surface and subsurface drainage, and potential methods for sediment retention.
We proposed to explore the subsurface conditions by completing four small diameter test borings
in the street area to maximum depths of 10 to 15 feet below street level, or auger refusal,
whichever is shallower, and completing two dynamic cone penetrometer soundings to five feet.
The cone penetrometer soundings will be completed using light, portable equipment and will be
used behind the sidewalk area to estimate the depth of loose material.
Samples of the subsurface soils will be taken at nominal five-foot increments in the borings by
conventional standard penetration tests. The cone soundings will consist of driving a 1.5 inch
diameter cone into the soil with a free falling, 35 pound driving, apparatus. The actual blow
counts will be recorded in 4-inch (100 millimeter) increments and will be converted to dynamic
cone resistance and equivalent SPT-blow counts by a computer program.
A Kleinfelder staff member will maintain a log of the soils encountered in the borings and obtain
samples for visual classification and laboratory testing. We anticipate that laboratory program
will consist of the following tests:
Three Sieve Analyses
0 One Plasticity Index
0 One Direct Shear Test
Eight Unit Weighthloisture Contents
Based upon the results of our field exploration, laboratory testing, and engineering analyses, we
will provide the following:
Discussion of the surface and subsurface conditions;
Total stress and unit weight properties of the retained and foundation soils for retaining
wall designs;
Recommendations for ranges of total stress and unit weight properties of typical soil
types for retaining wall drainage fill and the reinforced (infill) soil zone;
Bearing capacity of the retaining wall foundation soils, including recommendations for a
foundation leveling pad, minimum foundation embedment, and anticipated foundation
settlement;
Recommendations for retaining wall drainage and toe-of-slope;
Discussion of methods to anchor existing pipelines or relocate them, if required;
Guidelines for earthwork construction, including recommendations for site preparation,
fill placement, and compaction.

KLEINFELDER PROPOSAL NO. SI-YP7-147
The purpose of this memorandum is to confirm our conversation of this morning regarding our
lump sum fee to provide the Park Drive SloughingDrainage Study. We understand that due to
budget constraints the City has set a cap on our work for this project at about $1 7,000.00. As we
discussed, Kleinfelder agrees to complete this work for a lump sum fee of $1 6.999 with the
following understanding:
1. The scope of work as described in our July 17, 1997 letter will be completed. However. if
Kleinfelder finds fairly similar conditions in three of the lower slope borings and the two
cone penetration tests, we have the right to drop the fourth boring. We do not intend to delete
the fourth boring if we feel that any significant information may be lost. Furthermore, the
boring deleted would not be one of the borings we had intended to provide in the area of
obvious seepage.
2. The scope of work as described in our fax of August 1. 1997 will also be completed for three
borings at the top of the slope. The order of drilling would be for the desilting basin first. the
terrace below the desilting bzsin second, and the park area third. Please note that for the
original subcontractor services for Task 1 of Table 1 B, our costs were based on three borings
up to depths of 50 feet for a maximum total of 150 lineal feet. The reference to 200 lineal
feet for that table was a typographical cq-over from Table 1 A.
3. Kleinfelder understands that a separate contract will not be executed for this project. The
work for this project will be completed as a task order under our existing contract with the
City of Carlsbad. However, the limitations contained in our letter of July 17"' and the
submitted ASFE guidelines will still apply to our work.

SUBJECT: DESCWPTLON OF WORK FOR SOIL BORINGS AT TOP OF SLOPE
FOR PARK DMVE SLOPE/DRAlSAGE STUDY
The purpose of this memorandum is to provide you with information regarding driliing three soi
borings at the top of the slope running along Park drivc in Carlsbad. Thc purposc of the soi
borings ac to evaluate the potential of perched water tabbies existing within the slop. WI
anticipate drilling thc borings over a period of thee days using n C.M.F. truck mounted dr-iII rig
Moles will be drilled with a nolninal6-inch to &inch diameter auger. ?'here will also bc a For(
Ranger pickup truck at the site to suppor~ our :nginecdgeologist in the field for logging the soil:
encountered.
Wc plan to opcratc the rig between the hours of 730 a.m. and 450 p.m. on weekdays. Thc nois:
level during operation of thc rig will the similar to the noise created by operating u GOkW, diesel
poweyed generator. X7e rig wiIl remain at tke site ovcnight to reduce the potentid of dnmcging
the site by driving back and forth over the sire seved times. We would like to close tlx
sidewalk for the entire time the rig is at thc site for the safety of the residents.
We plan to keep disturbance of landscaping to wry low levels. In order to reduce the potential el
rutting soils in the grassy park area; imgation should bc sropped one week before we perform OUT
soil borings. If the soil is wet, ru'Is may be up to 24 inches deep Wc also plm to stay on the
sidewalk area as much BS possible to reduce the potential of rutting. We will cut 1hc sod, rcmove
it, and preserve the removed piece in the actual ma we will be drilling. Sheets of plastic or
plywood will bc laid down around the auger to collcct soil cuttings so as not to kill the grass in
the wea of our boring. To access the boring our on the terrace, wc will have to remove a section
of t5c wood fence.
After completion or our work at the sire, boreholes will be backfilled with the soil cutrings.
Excess soil cmings will be removcc! from the park ares and spread out in thc areas containing
natural vegebtio:1 outside thc wuoden fence or within the desilting basin. Thc sod that M';IS
removed will be put back into place and rails ren~oved from the fence will be nailed back into
place. We will r.otify you when our field work is conlplcted so that you may contzct the hornc
ow~~ers urnciation and t~cy can then rzsurne irrigahn at their conveniencc.
