EPT. PW PARK DRIVE, PROJECT NO. 3478
RECOMMENDED ACTION:
Adopt Resolution No. 3- 6% I authorizing the Finance Director to appropriate additional funds and approving a consultant agreement with Kleinfelder, Incorporated, for a geotechnical study including testing and recommendations for the soil sloughing and drainage problems along the northeast side of Park Drive.
ITEM EXPLANATION:
The purpose of the study by a soils engineer is to develop and evaluate various alternatives that will solve a drainage and soil sloughing problem that is occurring at the north east side of Park Drive from Bayshore Drive to approximately 500 feet north of Marina Drive (project site). During the widening of Park Drive in 1987, the bluff at the project site was cut back for the construction. Water continuously percolates through the bluff causing soil erosion and a water hazard on Park
sidewalk being covered with water, green algae growth and soil. Due to the high density residential Drive and the adjacent sidewalk. Pedestrians are often forced to walk in the street due to the
neighborhood, the east side of the street is often used for parking which makes it difficult for
which is recommended by this study, staff will return to Council for approval of funding and pedestrians to walk if they must step off the sidewalk. Prior to proceeding with any type of project
environmental clearance.
The soils engineering firm of Kleinfelder, Incorporated is recommended by staff for this study. The firm was the best qualified of the two (2) firms that were requested to submit a proposal for the study in July 1997.
Staff recommends that the City Council approve the attached consultant agreement with Kleinfelder,

Proposal No. 51-YP7-147
Mr. Galen N. Peterson, Consulting Project Manager
City of Carlsbad Engineering Department
2075 Las Palmas Drive
Carlsbad, California 92009-4589
Subject: Geotechnical Proposal for Park Drive SloughinglDrainage Study
Carlsbad, California
Dear Mr. Peterson:
Kleinfelder is pleased to present this proposal for performing a geotechnical study to provide
recommendations for the soil sloughing and drainage problems along Park Drive in the City of
Carlsbad, California. This proposal is based on our review of your letter of July 9. 1997 which
requested this proposal and described the general problems, problem area. and anticipated
contents of the proposal. The following sections describe our understanding of the proposed
project, scope of Kleinfelder services, our approach to the project plan, personnel to be assigned
the project, schedule, our current workload, and fees. We have also included our current
Standard Form 254.
PROJECT DESCRIPTION
Based on our preliminary site visit of July 15,1997, it is obvious that about 500 feet of the east
side of Park Drive just north of Marina Drive is experiencing some drainage and soil sloughing
problems. Water reportedly continuously percolates through the lower portion of the slope. and
we observed draining and ponded water during our recent site visit. Cattails and bamboo tend to
confirm that the areas are probably continuously wet. The drainage for the existing retaining
walls is primarily through open joints in the face of the wall which allow drainage and soil to
accumulate on the sidewalk area. The existing pipe drain collections system appears inadequate
and simply conducts the water through the sidewalk area where it tends to collect on the street.
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 is
experiencing typical bluff erosion similar to sea cliffs adjacent to the Pacific Ocean.
Accumulations of erosion material at the base of the bluff are apparently washing further down
the lower section of the bluff, over the existing rctaining walls, and are being deposited on the
5l-Yr7-l4n517rGl5l,Dc€
Copyright 1991 Klcinfeldcr, Inc, Page I 01'10 July 17. 1997
sidewalk and street. Based on our preliminary site visit, we did not note any conditions which
could indicate that the gross stability of the bluff was being impacted other than the continuous
erosion and occasional surface related sloughing as portions of the bluff are undermined by
erosion.
Two pipelines are visible along the slope above the sidewalk area which are being uncovered by
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 consider that two primary
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 subset
problems of how to mitigate the erosion and how to reduce the. eroded sediment
transportation to the sidewalk and street areas.
The most likely approach to the drainage is to add additional drainage and low retaining walls.
The walls may also reduce the amount of sediment reaching the street during storm periods.
Portions of the existing walls may need to be replaced to provide a better drainage system. We
anticipate that all drainage will be collected at the upper subsurface with a drainage collection
trench and carried to a suitable underground sewer.
For the erosion and sediment, we anticipate that we will need to complete a geologic
reconnaissance of the bluff to evaluate the effects of erosion and to provide recommendations for
potential measures. At this time we anticipate that some type of aesthetically acceptable storage
method will be required that will accommodate temporary storage and periodic removal of
accumulated sediment. We do not foresee that increasing the height of existing retaining walls or
alteration of the bluff face will be either practical, economical, or acceptable to the City Parks
and Recreation Commission.
SCOPE OF SERVICES
The scope of Kleinfelder’s service will be to complete a geologic evaluation of the bluff and a
limited geotechnical study at the bluff toe to evaluate foundations design parameters for new
retaining walls and a subdrain system. The specific tasks to be completed include:

Task 1: Initial Meeting with City Engineering
The purpose of this meeting will be to go over Kleinfelder’s proposal and work plan. Our senior
engineer will attend this meeting with the Consulting Project Manager and any pertinent staff
from the Engineering Department. Someone from the Maintenance Department who is aware of
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 reconnaissaice 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 landslide 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 also compute a pseudo-
static slope stability factor of safety using a seismic component of 0.ljg 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 IO 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
One Direct Shear Test
Eight Unit WeightMoisture 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.

may need to revise our fee estimate. We understand that accurate data on locations of property
lines, existing structures. underground utilities, and services will be provided. Kleinfelder will
not assume responsibility for disruption of utilities not accurately located. Time spent for
difficult site access will be charged on a time-and-expense basis, and the repair of damaged
utilities will be billed at cost.
The proposed investigation specially excludes the assessment of environmental characteristics.
particularly those involving hazardous waste materials. If a known contamination exists. site
environmental assessment may be appropriate prior to development. Kleinfelder would be
pleased to outline a scope of service for such an assessment in a separate proposal.
In the event that obviously suspicious subsurface materials are encountered visually or by odor in
our geotechnical exploration, we will stop OUT investigation and notify your office. All added
costs incurred as a result of suspected hazardous substances would be charged on a time-and-
expense basis over and above the estimated fees for the site investigation.
Items of work and analysis which a& specifically excluded from our scope of services include:
Actual design of the retaining walls or their drainage systems;
Field surveying of exploration locations;
Any cost estimates associated with the proposed construction;
Studies for availability of construction materials and evaluation of borrow sites;

KLEINFELDER PROPOSAL NO. 51-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 ow 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 $16.999 with the
following understanding:
I. 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 I. 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 basin 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 carry-over from Table 1 A.
3. Kleinfelder understands that a separate contract will net 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 17Ih and the
submitted ASFE guidelines will still apply to our work.

FOR PARK DRIVE SLOPE/DMAGE STUDY
The pqmx ofthis memorandum is to provide you with information nzgarding drilling three soil
borings at the top of the slope running along Park drive in Carlsbad. Thc purposc of thc soil
borings arc KO evaluate the potential of perched water tabies~existing within the slop. We
anticipate drilling thc borings over a period of thee &ys using n C.M.E. truck mounted drill rig.
Moles will be drilled with a nominal Cinch to 8-inch diameter auger. 'Iherc will also be a Ford
Ranger pickup truck at the site to support OUT engineer/geologisl in the field for logging the soils
encountered.
We plm to operate the rig between the hours of 730 a.m. und 430 p.m. on weekdays. Thc noise
level during operation of thc rig will the similar to the noise created by operating u 60kW, diesel
powered generator. Tic rig will ramin at lhe site overnight to reduce the potential of damnping
thc site by driving back forth over the site several times. We would like to close the
sidewalk for the entire time the rig is ut the site for the safety ofthe residenu.
We plan to keep disturbance of landscaping to vcry low levels. In order to reduce the potential or
runing soils in the gmssy park area, irrigation should bc s~oppcd one week before we perform our
soil borings. If the soil is wet. ruu may be up to 24 inches deep. Wc also plan to my on the
sidewalk area M much as possible to reduce the potential of rutting. We will cut thc sod. rcmovc
it, and preserve the removed piece in the actual arca we will be drilling. Sheets of plastic or
plywood will be laid down around the auger IO collcct soil cunhgs so M no: to kill tlae pars in

Affn completion of OUT work at the site, boreholes will be backfilled with the soil cuttings. Excess soil cunings will be removcd from the park urea and spread out in thc areas cor~taining
nsrural vegetation outside thr: wooden fence or within the dcsilting basin. Thc sod that WJS
removed will be put back into place and rails removed from the fence will be nailed back into
