BACKGROUND AND DISCUSSION:
The City Council approved the update to the Portuguese Bend Feasibility Study at its
August 7, 2018, meeting. The City Council Subcommittee for the Landslide Feasibility
Study Update reviewed and edited the Request for Proposals (RFP) document for
Engineering Analysis, Evaluation, and Design for improvements in the Portuguese Bend
1
Landslide to include Drainage and Dewatering (hydro-augers). The RFP document
(Attachment B) was released October 11, 2018. Several consultants were directly
contacted by Staff and the RFP was published on the City’s website in an extended
effort to solicit qualified consultants to submit proposals for the proposed project.
The RFP document asked consultants to provide proposals to the City for their services
including:
• Perform a hydrology study of the watershed including specific hydrologic and
engineering analysis of the watershed to identify as to where, what quantity, how,
and to what extent the stormwater runs off and/or infiltrates into the landslide and
becomes part of the groundwater in the Portuguese Bend Landslide Complex;
• Perform engineering analysis, evaluation, and designs for the lower portion of the
Portuguese Bend Landslide that would convey the drainage runoff to the ocean
directly;
• Design groundwater extraction horizontal drains (hydro-augers) for the lower
area of the landslide, including a cost benefit analysis for the hydro-augers and
any alternatives; and,
• Analyze and design repair plans if sealing fractures in the landslide area between
Palos Verdes Drive South and Burma Road is determined to be needed.
Two proposals were received by the November 12, 2018, submittal deadline. Both
proposals were reviewed and Daniel B. Stephens (Attachment C) was determined to be
the most qualified for the project and required process, including public input and
reviews. Following this determination, Staff entered into negotiations for the fee and to
further refine and narrow the final scope of work for the project.
If this Professional Services Agreement (Attachment A) is approved, the work will only
include: (1) the design of the drainage system at the bottom portion of the landslide
located to the south of Burma Road; (2) the design of any necessary fracture infill in
this area; (3) the design of the underground hydro-augers at the bottom of the slide;
and, (4) the hydrology/hydraulic analysis in the canyons. Any design work to potentially
line any or all of the canyons north of Burma Road is not included in this proposal.
Environmental review work associated with any part of the designs that will be
developed will be undertaken following City Council approval of the designs. As the
Consultant develops engineering designs, they will meet with Staff and applicable
State/Federal agencies as well as the Palos Verdes Peninsula Land Conservancy
(PVPLC) and the City Council Subcommittee to review those designs. A community
outreach meeting will follow to solicit comments on the initial conceptual design of
mitigation efforts, and a 30-day public comment period will be provided to review
proposed design concepts and siting of proposed designed improvements.
Modifications to the design and locations, if needed, will be completed prior to
proceeding with the ensuing design of the Portuguese Bend Landslide Mitigation
Project. A final public outreach meeting will be conducted and the review and plan
update process repeated prior to bringing the final design plans to the City Council for
review and approval.
2
Based on their clear understanding of project constraints, local geology, movement and
general characteristics of the landslide, along with the results of the negotiations
associated with project scope and cost, Staff is recommending approval of the
Professional Services Agreement with Daniel B. Stephens & Associates, Inc. to perform
design services for this project.
ALTERNATIVES:
In addition to the Staff recommendations, the following alternative action is available for
the City Council’s consideration:
1. Discuss and provide recommendations on other options that may be
appropriate.

under this Agreement does not comply with these specifications or is canceled and not replaced,
A-11
01203.0006/524815.6 11
City has the right but not the duty to obtain the insurance it deems necessary and any premium
paid by City will be promptly reimbursed by Consultant or City will withhold amounts sufficient
to pay premium from Consultant payments. In the alternative, City may cancel this Agreement.
(e) Acceptable insurers. All insurance policies shall be issued by an insurance
company currently authorized by the Insurance Commissioner to transact business of insurance
or that is on the List of Approved Surplus Line Insurers in the State of California, with an
assigned policyholders’ Rating of A- (or higher) and Financial Size Category Class VI (or larger)
in accordance with the latest edition of Best’s Key Rating Guide, unless otherwise approved by
the City’s Risk Manager.
(f) Waiver of subrogation. All insurance coverage maintained or procured
pursuant to this agreement shall be endorsed to waive subrogation against City, its elected or
appointed officers, agents, officials, employees and volunteers or shall specifically allow
Consultant or others providing insurance evidence in compliance with these specifications to
waive their right of recovery prior to a loss. Consultant hereby waives its own right of recovery
against City, and shall require similar written express waivers and insurance clauses from each of
its subConsultants.
(g) Enforcement of contract provisions (non-estoppel). Consultant
acknowledges and agrees that any actual or alleged failure on the part of the City to inform
Consultant of non-compliance with any requirement imposes no additional obligations on the
City nor does it waive any rights hereunder.
(h) Requirements not limiting. Requirements of specific coverage features or
limits contained in this section are not intended as a limitation on coverage, limits or other
requirements, or a waiver of any coverage normally provided by any insurance. Specific
reference to a given coverage feature is for purposes of clarification only as it pertains to a given
issue and is not intended by any party or insured to be all inclusive, or to the exclusion of other
coverage, or a waiver of any type. If the Consultant maintains higher limits than the minimums
shown above, the City requires and shall be entitled to coverage for the higher limits maintained
by the Consultant. Any available insurance proceeds in excess of the specified minimum limits of
insurance and coverage shall be available to the City.
(i) Notice of cancellation. Consultant agrees to oblige its insurance agent or
broker and insurers to provide to City with a thirty (30) day notice of cancellation (except for
nonpayment for which a ten (10) day notice is required) or nonrenewal of coverage for each
required coverage.
(j) Additional insured status. General liability policies shall provide or be
endorsed to provide that City and its officers, officials, employees, and agents, and volunteers
shall be additional insureds under such policies. This provision shall also apply to any
excess/umbrella liability policies.
(k) Prohibition of undisclosed coverage limitations. None of the coverages
required herein will be in compliance with these requirements if they include any limiting
endorsement of any kind that has not been first submitted to City and approved of in writing.
A-12
01203.0006/524815.6 12
(l) Separation of insureds. A severability of interests provision must apply for
all additional insureds ensuring that Consultant’s insurance shall apply separately to each insured
against whom claim is made or suit is brought, except with respect to the insurer’s limits of
liability. The policy(ies) shall not contain any cross-liability exclusions.
(m) Pass through clause. Consultant agrees to ensure that its subConsultants,
subcontractors, and any other party involved with the project who is brought onto or involved in
the project by Consultant, provide the same minimum insurance coverage and endorsements
required of Consultant. Consultant agrees to monitor and review all such coverage and assumes
all responsibility for ensuring that such coverage is provided in conformity with the requirements
of this section. Consultant agrees that upon request, all agreements with Consultants,
subcontractors, and others engaged in the project will be submitted to City for review.
(n) Agency’s right to revise specifications. The City reserves the right at any
time during the term of the contract to change the amounts and types of insurance required by
giving the Consultant ninety (90) days advance written notice of such change. If such change
results in substantial additional cost to the Consultant, the City and Consultant may renegotiate
Consultant’s compensation.
(o) Self-insured retentions. Any self-insured retentions must be declared to
and approved by City. City reserves the right to require that self-insured retentions be eliminated,
lowered, or replaced by a deductible. Self-insurance will not be considered to comply with these
specifications unless approved by City.
(p) Timely notice of claims. Consultant shall give City prompt and timely
notice of claims made or suits instituted that arise out of or result from Consultant’s performance
under this Agreement, and that involve or may involve coverage under any of the required
liability policies.
(q) Additional insurance. Consultant shall also procure and maintain, at its
own cost and expense, any additional kinds of insurance, which in its own judgment may be
necessary for its proper protection and prosecution of the work.
5.3 Indemnification.
To the full extent permitted by law, Consultant agrees to indemnify, defend and hold
harmless the City, its officers, employees and agents (“Indemnified Parties”) against, and will
hold and save them and each of them harmless from, any and all actions, either judicial,
administrative, arbitration or regulatory claims, damages to persons or property, losses, costs,
penalties, obligations, errors, omissions or liabilities whether actual or threatened (herein “claims
or liabilities”) that may be asserted or claimed by any person, firm or entity arising out of or in
connection with the negligent performance of the work, operations or activities provided herein
of Consultant, its officers, employees, agents, subcontractors, or invitees, or any individual or
entity for which Consultant is legally liable (“indemnitors”), or arising from Consultant’s or
indemnitors’ reckless or willful misconduct, or arising from Consultant’s or indemnitors’
negligent performance of or failure to perform any term, provision, covenant or condition of this
Agreement, and in connection therewith:
A-13
01203.0006/524815.6 13
(a) Consultant will defend any action or actions filed in connection with any
of said claims or liabilities and will pay all costs and expenses, including legal costs and
attorneys’ fees incurred in connection therewith;
(b) Consultant will promptly pay any judgment rendered against the City, its
officers, agents or employees for any such claims or liabilities arising out of or in connection
with the negligent performance of or failure to perform such work, operations or activities of
Consultant hereunder; and Consultant agrees to save and hold the City, its officers, agents, and
employees harmless therefrom;
(c) In the event the City, its officers, agents or employees is made a party to
any action or proceeding filed or prosecuted against Consultant for such damages or other claims
arising out of or in connection with the negligent performance of or failure to perform the work,
operation or activities of Consultant hereunder, Consultant agrees to pay to the City, its officers,
agents or employees, any and all costs and expenses incurred by the City, its officers, agents or
employees in such action or proceeding, including but not limited to, legal costs and attorneys’
fees.
Consultant shall incorporate similar indemnity agreements with its subcontractors and if
it fails to do so Consultant shall be fully responsible to indemnify City hereunder therefore, and
failure of City to monitor compliance with these provisions shall not be a waiver hereof. This
indemnification includes claims or liabilities arising from any negligent or wrongful act, error or
omission, or reckless or willful misconduct of Consultant in the performance of professional
services hereunder. The provisions of this Section do not apply to claims or liabilities occurring
as a result of City’s sole negligence or willful acts or omissions, but, to the fullest extent
permitted by law, shall apply to claims and liabilities resulting in part from City’s negligence,
except that design professionals’ indemnity hereunder shall be limited to claims and liabilities
arising out of the negligence, recklessness or willful misconduct of the design professional. The
indemnity obligation shall be binding on successors and assigns of Consultant and shall survive
termination of this Agreement.
ARTICLE 6. RECORDS, REPORTS, AND RELEASE OF INFORMATION
6.1 Records.
Consultant shall keep, and require subcontractors to keep, such ledgers, books of
accounts, invoices, vouchers, canceled checks, reports, studies or other documents relating to the
disbursements charged to City and services performed hereunder (the “books and records”), as
shall be necessary to perform the services required by this Agreement and enable the Contract
Officer to evaluate the performance of such services. Any and all such documents shall be
maintained in accordance with generally accepted accounting principles and shall be complete
and detailed. The Contract Officer shall have full and free access to such books and records at all
times during normal business hours of City, including the right to inspect, copy, audit and make
records and transcripts from such records. Such records shall be maintained for a period of three
(3) years following completion of the services hereunder, and the City shall have access to such
records in the event any audit is required. In the event of dissolution of Consultant’s business,
custody of the books and records may be given to City, and access shall be provided by
Consultant’s successor in interest. Notwithstanding the above, the Consultant shall fully
A-14
01203.0006/524815.6 14
cooperate with the City in providing access to the books and records if a public records request is
made and disclosure is required by law including but not limited to the California Public Records
Act.
6.2 Reports.
Consultant shall periodically prepare and submit to the Contract Officer such reports
concerning the performance of the services required by this Agreement as the Contract Officer
shall require. Consultant hereby acknowledges that the City is greatly concerned about the cost of
work and services to be performed pursuant to this Agreement. For this reason, Consultant agrees
that if Consultant becomes aware of any facts, circumstances, techniques, or events that may or
will materially increase or decrease the cost of the work or services contemplated herein or, if
Consultant is providing design services, the cost of the project being designed, Consultant shall
promptly notify the Contract Officer of said fact, circumstance, technique or event and the
estimated increased or decreased cost related thereto and, if Consultant is providing design
services, the estimated increased or decreased cost estimate for the project being designed.
6.3 Ownership of Documents.
All drawings, specifications, maps, designs, photographs, studies, surveys, data, notes,
computer files, reports, records, documents and other materials (the “documents and materials”)
prepared by Consultant, its employees, subcontractors and agents in the performance of this
Agreement shall be the property of City and shall be delivered to City upon request of the
Contract Officer or upon the termination of this Agreement, and Consultant shall have no claim
for further employment or additional compensation as a result of the exercise by City of its full
rights of ownership use, reuse, or assignment of the documents and materials hereunder. Any use,
reuse or assignment of such completed documents for other projects and/or use of uncompleted
documents without specific written authorization by the Consultant will be at the City’s sole risk
and without liability to Consultant, and Consultant’s guarantee and warranties shall not extend to
such use, reuse or assignment. Consultant may retain copies of such documents for its own use.
Consultant shall have the right to use the concepts embodied therein. All subcontractors shall
provide for assignment to City of any documents or materials prepared by them, and in the event
Consultant fails to secure such assignment, Consultant shall indemnify City for all damages
resulting therefrom. Moreover, Consultant with respect to any documents and materials that may
qualify as “works made for hire” as defined in 17 U.S.C. § 101, such documents and materials
are hereby deemed “works made for hire” for the City.
6.4 Confidentiality and Release of Information.
(a) All information gained or work product produced by Consultant in
performance of this Agreement shall be considered confidential, unless such information is in the
public domain or already known to Consultant. Consultant shall not release or disclose any such
information or work product to persons or entities other than City without prior written
authorization from the Contract Officer.
(b) Consultant, its officers, employees, agents or subcontractors, shall not,
without prior written authorization from the Contract Officer or unless requested by the City
A-15
01203.0006/524815.6 15
Attorney, voluntarily provide documents, declarations, letters of support, testimony at
depositions, response to interrogatories or other information concerning the work performed
under this Agreement. Response to a subpoena or court order shall not be considered “voluntary”
provided Consultant gives City notice of such court order or subpoena.
(c) If Consultant, or any officer, employee, agent or subcontractor of
Consultant, provides any information or work product in violation of this Agreement, then City
shall have the right to reimbursement and indemnity from Consultant for any damages, costs and
fees, including attorney’s fees, caused by or incurred as a result of Consultant’s conduct.
(d) Consultant shall promptly notify City should Consultant, its officers,
employees, agents or subcontractors be served with any summons, complaint, subpoena, notice
of deposition, request for documents, interrogatories, request for admissions or other discovery
request, court order or subpoena from any party regarding this Agreement and the work
performed there under. City retains the right, but has no obligation, to represent Consultant or be
present at any deposition, hearing or similar proceeding. Consultant agrees to cooperate fully
with City and to provide City with the opportunity to review any response to discovery requests
provided by Consultant. However, this right to review any such response does not imply or mean
the right by City to control, direct, or rewrite said response.
ARTICLE 7. ENFORCEMENT OF AGREEMENT AND TERMINATION
7.1 California Law.
This Agreement shall be interpreted, construed and governed both as to validity and to
performance of the parties in accordance with the laws of the State of California. Legal actions
concerning any dispute, claim or matter arising out of or in relation to this Agreement shall be
instituted in the Superior Court of the County of Los Angeles, State of California, or any other
appropriate court in such county, and Consultant covenants and agrees to submit to the personal
jurisdiction of such court in the event of such action. In the event of litigation in a U.S. District
Court, venue shall lie exclusively in the Central District of California, in the County of Los
Angeles, State of California.
7.2 Disputes; Default.
In the event that Consultant is in default under the terms of this Agreement, the City shall
not have any obligation or duty to continue compensating Consultant for any work performed
after the date of default. Instead, the City may give notice to Consultant of the default and the
reasons for the default. The notice shall include the timeframe in which Consultant may cure the
default. This timeframe is presumptively thirty (30) days, but may be extended, though not
reduced, if circumstances warrant. During the period of time that Consultant is in default, the
City shall hold all invoices and shall, when the default is cured, proceed with payment on the
invoices. In the alternative, the City may, in its sole discretion, elect to pay some or all of the
outstanding invoices during the period of default. If Consultant does not cure the default, the City
may take necessary steps to terminate this Agreement under this Article. Any failure on the part
of the City to give notice of the Consultant’s default shall not be deemed to result in a waiver of
the City’s legal rights or any rights arising out of any provision of this Agreement.
A-16
01203.0006/524815.6 16
7.3 Retention of Funds.
Consultant hereby authorizes City to deduct from any amount payable to Consultant
(whether or not arising out of this Agreement) (i) any amounts the payment of which may be in
dispute hereunder or which are necessary to compensate City for any losses, costs, liabilities, or
damages suffered by City, and (ii) all amounts for which City may be liable to third parties, by
reason of Consultant’s acts or omissions in performing or failing to perform Consultant’s
obligation under this Agreement. In the event that any claim is made by a third party, the amount
or validity of which is disputed by Consultant, or any indebtedness shall exist which shall appear
to be the basis for a claim of lien, City may withhold from any payment due, without liability for
interest because of such withholding, an amount sufficient to cover such claim. The failure of
City to exercise such right to deduct or to withhold shall not, however, affect the obligations of
the Consultant to insure, indemnify, and protect City as elsewhere provided herein.
7.4 Waiver.
Waiver by any party to this Agreement of any term, condition, or covenant of this
Agreement shall not constitute a waiver of any other term, condition, or covenant. Waiver by any
party of any breach of the provisions of this Agreement shall not constitute a waiver of any other
provision or a waiver of any subsequent breach or violation of any provision of this Agreement.
Acceptance by City of any work or services by Consultant shall not constitute a waiver of any of
the provisions of this Agreement. No delay or omission in the exercise of any right or remedy by
a non-defaulting party on any default shall impair such right or remedy or be construed as a
waiver. Any waiver by either party of any default must be in writing and shall not be a waiver of
any other default concerning the same or any other provision of this Agreement.
7.5 Rights and Remedies are Cumulative.
Except with respect to rights and remedies expressly declared to be exclusive in this
Agreement, the rights and remedies of the parties are cumulative and the exercise by either party
of one or more of such rights or remedies shall not preclude the exercise by it, at the same or
different times, of any other rights or remedies for the same default or any other default by the
other party.
7.6 Legal Action.
In addition to any other rights or remedies, either party may take legal action, in law or in
equity, to cure, correct or remedy any default, to recover damages for any default, to compel
specific performance of this Agreement, to obtain declaratory or injunctive relief, or to obtain
any other remedy consistent with the purposes of this Agreement. Notwithstanding any contrary
provision herein, Consultant shall file a statutory claim pursuant to Government Code Sections
905 et seq. and 910 et seq., in order to pursue a legal action under this Agreement.
7.7 Liquidated Damages.
Since the determination of actual damages for any delay in performance of this
Agreement would be extremely difficult or impractical to determine in the event of a breach of
A-17
01203.0006/524815.6 17
this Agreement, the Contractor and its sureties shall be liable for and shall pay to the City the
sum of zero ($0.00) as liquidated damages for each working day of delay in the performance of
any service required hereunder. The City may withhold from any monies payable on account of
services performed by the Contractor any accrued liquidated damages.
7.8 Termination Prior to Expiration of Term.
This Section shall govern any termination of this Contract except as specifically provided
in the following Section for termination for cause. The City reserves the right to terminate this
Contract at any time, with or without cause, upon thirty (30) days ’ written notice to Consultant,
except that where termination is due to the fault of the Consultant, the period of notice may be
such shorter time as may be determined by the Contract Officer. In addition, the Consultant
reserves the right to terminate this Contract at any time, with or without cause, upon sixty (60)
days ’ written notice to City, except that where termination is due to the fault of the City, the
period of notice may be such shorter time as the Consultant may determine. Upon receipt of any
notice of termination, Consultant shall immediately cease all services hereunder except such as
may be specifically approved by the Contract Officer. Except where the Consultant has initiated
termination, the Consultant shall be entitled to compensation for all services rendered prior to the
effective date of the notice of termination and for any services authorized by the Contract Officer
thereafter in accordance with the Schedule of Compensation or such as may be approved by the
Contract Officer, except as provided in Section 7.3. In the event the Consultant has initiated
termination, the Consultant shall be entitled to compensation only for the reasonable value of the
work product actually produced hereunder. In the event of termination without cause pursuant to
this Section, the terminating party need not provide the non-terminating party with the
opportunity to cure pursuant to Section 7.2.
7.9 Termination for Default of Consultant.
If termination is due to the failure of the Consultant to fulfill its obligations under this
Agreement, City may, after compliance with the provisions of Section 7.2, take over the work
and prosecute the same to completion by contract or otherwise, and the Consultant shall be liable
to the extent that the total cost for completion of the services required hereunder exceeds the
compensation herein stipulated (provided that the City shall use reasonable efforts to mitigate
such damages), and City may withhold any payments to the Consultant for the purpose of set-off
or partial payment of the amounts owed the City as previously stated.
7.10 Attorneys’ Fees.
If either party to this Agreement is required to initiate or defend or made a party to any
action or proceeding in any way connected with this Agreement, the prevailing party in such
action or proceeding, in addition to any other relief which may be granted, whether legal or
equitable, shall be entitled to reasonable attorney’s fees. Attorney’s fees shall include attorney’s
fees on any appeal, and in addition a party entitled to attorney’s fees shall be entitled to all other
reasonable costs for investigating such action, taking depositions and discovery and all other
necessary costs the court allows which are incurred in such litigation. All such fees shall be
deemed to have accrued on commencement of such action and shall be enforceable whether or
not such action is prosecuted to judgment.

ARTICLE 8. CITY OFFICERS AND EMPLOYEES: NON-DISCRIMINATION
8.1 Non-liability of City Officers and Employees.
No officer or employee of the City shall be personally liable to the Consultant, or any
successor in interest, in the event of any default or breach by the City or for any amount which
may become due to the Consultant or to its successor, or for breach of any obligation of the terms
of this Agreement.
8.2 Conflict of Interest.
Consultant covenants that neither it, nor any officer or principal of its firm, has or shall
acquire any interest, directly or indirectly, which would conflict in any manner with the interests
of City or which would in any way hinder Consultant’s performance of services under this
Agreement. Consultant further covenants that in the performance of this Agreement, no person
having any such interest shall be employed by it as an officer, employee, agent or subcontractor
without the express written consent of the Contract Officer. Consultant agrees to at all times
avoid conflicts of interest or the appearance of any conflicts of interest with the interests of City
in the performance of this Agreement.
No officer or employee of the City shall have any financial interest, direct or indirect, in
this Agreement nor shall any such officer or employee participate in any decision relating to the
Agreement which affects her/his financial interest or the financial interest of any corporation,
partnership or association in which (s)he is, directly or indirectly, interested, in violation of any
State statute or regulation. The Consultant warrants that it has not paid or given and will not pay
or give any third party any money or other consideration for obtaining this Agreement.
8.3 Covenant Against Discrimination.
Consultant covenants that, by and for itself, its heirs, executors, assigns, and all persons
claiming under or through them, that there shall be no discrimination against or segregation of,
any person or group of persons on account of race, color, creed, religion, sex, gender, sexual
orientation, marital status, national origin, ancestry or other protected class in the performance of
this Agreement. Consultant shall take affirmative action to insure that applicants are employed
and that employees are treated during employment without regard to their race, color, creed,
religion, sex, gender, sexual orientation, marital status, national origin, ancestry or other
protected class.
8.4 Unauthorized Aliens.
Consultant hereby promises and agrees to comply with all of the provisions of the Federal
Immigration and Nationality Act, 8 U.S.C. § 1101 et seq., as amended, and in connection
therewith, shall not employ unauthorized aliens as defined therein. Should Consultant so employ
such unauthorized aliens for the performance of work and/or services covered by this Agreement,
and should any liability or sanctions be imposed against City for such use of unauthorized aliens,
Consultant hereby agrees to and shall reimburse City for the cost of all such liabilities or
sanctions imposed, together with any and all costs, including attorneys’ fees, incurred by City.

EXHIBIT “A”
SCOPE OF SERVICES
I. Consultant will perform the following Services: Consultant will complete a
hydrology study of the watershed, including a specific hydrologic information
and engineering analysis of the Canyons to identify where, what quantity, how,
and to what extent the stormwater infiltrates into the groundwater in the
Portuguese Bend Landslide Complex. Based on a the hydrology study and
resultant water balance analysis, Consultant will develop the engineering
analysis required to evaluate, and provide a design for, the lower portion of the
Portuguese Bend Landslide in order to convey the drainage runoff to the ocean
directly, and Consultant will provide the design and placement location to bring
about the quantity of groundwater extraction through horizontal drains (hydro-
augers) for the lower area of the landslide to achieve the design goals.
Summary of the Tasks:
• Review existing records and field inventory with design team.
• Perform Hydrology analysis and the water balance for the entire watershed.
• Determine areas that require fracture in-filling located south of Burma Road.
• Design of the Hydro-Augers, determine their placement, drainage design and
perform a cost-benefit analysis specific to proposed improvements.
• Provide utility identification and coordination for proposed construction activities.
• Develop construction plan sheets based on engineering design.
• Develop the Engineer’s Estimate and estimated project cost and construction
schedule.
• Develop the Technical Specifications and applicable Special Provisions.
• Develop the Bid document package.
• Attend monthly meetings with regulatory agency interaction and answer questions
or requests for information (RFI) through the project bidding process).
• Develop all final project deliverables and as-built drawings.
• Perform all project Surveying.
• Provide updates for the City’s website specific to design services and public
outreach meetings.
• Attend meetings including project kickoff meeting, three City Council Meetings,
two public outreach meetings.
Services by Task
A. TASK A: Project kick-off meeting
1. Key members of Consultant’s project team will meet with City staff to
outline the drainage and dewatering design project in detail before major
tasks commence. Consultant will present its proposed WBS and project
schedule along with a summary of the major tasks and its approach to each
task and subtask. The lines of communication between team members, the
A-25
01203.0006/524815.6 A-5
City and community, and other stakeholders will also be discussed. Data
needs from the City and major deliverables will be outlined in order to
achieve a common understanding regarding the overall project as well as
proposed methodologies, engineering technologies, and dewatering/
drainage and landslide mitigation goals.
B. TASK B: Review Existing Records/Field Inventory
1. Consultant has already comprehensively reviewed the key reports in the
City’s document library during document compilation and review during
the Portuguese Bend Feasibility Study Update (“FS Update”, found here:
http://www.rpvca.gov/documentcenter/view/12275) preparation. The key
documents and data will be further incorporated into new work as needed
in Consultant’s planning and design tasks to be completed for the
proposed scope of work. Consultant will work with City staff to further
identify any additional documents to add to the library as needed.
C. TASK C: Develop Project Hydrology Analysis
Consultant will collect critical field data in order to perform an accurate and
meaningful Water Balance to support project design. Therefore, the Hydrologic
Analysis will include field data collection (Task C1) to prepare an optimized
Water Balance to summarize available data and estimate the sources of
groundwater in the Red Zone area (Task C2). The Hydrologic Analysis will focus
on the Portuguese Canyon/Paint Brush Canyon Drainage Basin or subwatershed
(“Hydrologic Analysis Area”) as shown on the figure below. (See following
page.)

A-27
01203.0006/524815.6 A-7
D. TASK C1. Field Data Collection
Field data collection will consist of the following activities:
1. Streambed survey. Consultant will conduct a field survey for the
streambeds in Portuguese Canyon, Ishibashi Canyon, and Paintbrush
Canyon and associated tributaries (“the Canyons”). The purpose of the
field survey is to identify areas of flat or impounded topography where
surface water may be subject to enhanced infiltration and groundwater
recharge and to characterize other properties of the streambeds that govern
groundwater recharge.
2. Synoptic streamflow discharge survey. Following a wet-weather event,
Consultant will collect streamflow discharge data at several locations
along the Canyons. This data will be used to identify sections of the
Canyons where streamflow may recharge to groundwater and to estimate
groundwater recharge. If flow in the measured reach of the stream has
decreased from upstream to downstream, the decrease may be attributed to
streamflow recharging groundwater. This type of survey is commonly
referred to as a “seepage run.” Field methods will be consistent with U.S.
Geological Survey (USGS) techniques and will utilize staff gauges and
volumetric gauges (Rosenberry and LaBaugh, 2008). The timing of the
utility of this task is contingent on a suitable wet-weather event occurring
during the project period.
3. Surface water conveyance survey. Stormwater flowing through the
Canyons is currently routed to the Pacific Ocean through an existing storm
drain network constructed in the Red Zone area (figure shown on next
page). The surface conveyances will be visually surveyed to evaluate their
current location, condition, and current ability to transmit estimated peak
streamflow.
4. Groundwater well inspection survey. Information provided by the City
indicates that up to 20 dewatering wells have been constructed and
installed within the Hydrologic Analysis Area during previous mitigation
efforts. Except for four recent wells installed in 2016, no information
could be located that documents the well construction details, purpose of
each well (monitoring or dewatering), date of installation, well temporal
monitoring data, or the current status of the well, and the FS Update
recognized this limitation as a data gap that should be aggressively
addressed moving forward. Consultant will perform a well inspection
survey of wells in the Hydrologic Analysis Area, including, as appropriate,
down-hole video surveys and measurement of depth-to-groundwater,
wellhead elevation, well depth and diameter, and well screened interval.
Consultant will also perform limited aquifer testing of existing wells (e.g.,
slug tests) as a basis for estimating hydraulic aquifer properties.
A-28
01203.0006/524815.6 A-8
5. Irrigation Practices Survey. Within the Hydrologic Analysis Area,
landscape irrigation occurs within the Rolling Hills neighborhood and
adjacent City neighborhoods as well as within the Palos Verdes Nature
Preserve. Consultant will perform a visual field survey of landscape
irrigation practices, including irrigated areas, landscape vegetation (e.g.,
turf versus ornamentals), irrigation system, and the presence or absence of
overspray runoff to impervious surfaces that results in irrigation water
flow to the stormwater system. The irrigation practices survey will serve as
a basis for irrigation rate estimation for the water balance, described
below. Site access for Rolling Hills will be obtained by City.
E. TASK C2. Water Balance/Groundwater source assessment
1. Data collected under Task C1, described above, will be used in
conjunction with data collected from previous studies to develop an
optimized Water Balance of the Hydrologic Analysis Area. Within the
Hydrologic Analysis Area, a supplemental water balance will also be
conducted for the area of greatest land movement within the Portuguese
Landslide Complex (“Red Zone “) (figure below, see next page) to identify
significant sources of groundwater recharge and support design of the
dewatering system.

2. The Water Balance will consist of the following components:
a. Aquifer characterization and groundwater flow assessment.
Groundwater flow direction and volumetric flux will be estimated
based on the areal extent, thickness, and other physical
characteristics of the shallow aquifer underlying the Red Zone area
and canyons. To support this analysis, a groundwater elevation
map will be developed for the Hydrologic Analysis Area, and
cross-sections presented in the FS Update Appendix C will be
updated to project groundwater elevation throughout the upper
Canyon areas.
b. Groundwater data will be obtained from data collected under Task
C1, from previous studies as summarized in the FS Update, and if
available from the California Statewide Groundwater Elevation
Monitoring (CASGEM) Program and State Water Resources
Control Board GeoTracker website.
c. Groundwater elevation maps will be used to generate contours of
groundwater elevation and resulting estimated horizontal flow
paths. Groundwater underflow into the Red Zone and groundwater
outflow to the Pacific Ocean will be estimated.
d. Watershed modeling/groundwater recharge from precipitation and
irrigation. Groundwater recharge by precipitation occurs aerially
throughout the Hydrologic Analysis Area, and is also focused
within sections of the streams during wet-weather flow. Consultant
will employ the Distributed Parameter Watershed Model (DPWM)
developed by Consultant for this purpose. Parameterization of the
DPWM will be completed with publically available data and data
collected in Task C1. The widely-used Parameter-elevation
Regressions on Independent Slopes Model (PRISM) will be used
to generate precipitation rates that account for orographic effects
on a daily time step. Additional climactic data (e.g., wind speed,
temperature) will be accessed from local meteorological stations.
Vegetation data will be obtained from the USGS Gap Analysis
Program (GAP), and soils data will be obtained from the USDA
Soil Survey Geographic (SSURGO) and State Soil Geographic
(STATSGO) databases.
e. Irrigation rates will be estimated based on water-delivery records
(if available), the irrigation practices survey conducted under Task
C1, and literature references for irrigation rates in Southern
California (e.g., Costello and Jones, 2014). Irrigated areas will be
estimated based on the irrigation practices survey and review of
aerial photography.
A-31
01203.0006/524815.6 A-11
f. DPWM results will be documented in a series of maps and
diagrams that document model input data (e.g., topography, soils,
vegetation) and model simulated runoff volumes and deep
percolation to groundwater.
3. Septic system recharge. For domestic water users that use individual septic
systems, some of the household-consumed water is eventually recharged to
groundwater. The presence of septic systems within the Hydrologic
Analysis Area will be determined by comparison of the location of
residences and sewer infrastructure (e.g., FS Update Figure 7) in
consultation with appropriate City staff; it is assumed that septic systems
are present where residences are present and sewer pipes are absent. The
recharge rate for individual septic systems will be assumed to be 147.5
gallons per day (gpd) assuming 50 gpd per person based on a study of
septic system recharge within southern California (Hantzche and
Finnemore, 1992), and an average population of 2.95 persons per
household in California (U.S. Census Bureau, 2018). Alternatively, water
delivery records may be used if available to estimate domestic water usage
per household.
4. Change in groundwater storage. As reported in the FS Update,
groundwater levels have historically increased in this area due to increase
in the rate of groundwater recharge caused by the disruption of drainage
patterns and the opening of fissures and cracks following the onset of land
movement. Newly collected groundwater level data under Task C1, above,
will be compared to historical groundwater-level data reported in the FS
Update to estimate the change in groundwater storage over time.
5. ·Identification of Key Sources of Groundwater. Significant sources of
groundwater recharge to the Red Zone will be determined from the results
of the Water Balance. Groundwater recharge from all sources (e.g.,
irrigation, septic systems, precipitation) will be summarized in table and
graphical form. The results of the Water Balance will be used to provide
input on mitigation measures to reduce groundwater recharge. In addition,
DPWM will be used to support engineering design of the system
dewatering components.
F. TASK D. Fracture Sealing (In-filling)
As noted in historical reports for the Portuguese Bend area, stormwater has for
years flowed out of lower Portuguese, Ishibashi, and Paintbrush Canyons and
recharged directly into subsurface groundwater in the landslide head scarp area
south of lower Burma Road. Groundwater recharge in the head scarp area
promotes slope instability in the Portuguese Bend “Red Zone” area of greatest
displacement. Sealing this surface fracture area is key to preventing future
stormwater flow into the head scarp and additional lubrication of the slide plane
failure surface.
A-32
01203.0006/524815.6 A-12
1. This task consists of the following subtasks:
a. Field Survey
b. Evaluate Sealing Options
2. Consultant has already conducted a preliminary field survey of the fracture
areas while visiting the property on several dates in 2018. In addition,
Consultant obtained a high-resolution topographic map from the City that
shows landslide area topography with 1-foot elevation contours. The
topographic map shows several fractures in the landslide head scarp area.
Consultant imported the map into our GIS. Consultant will utilize the GIS
system to systematically identify key existing fractures before a
supplemental field survey is planned and completed. The GIS work and
sitewalk will be completed to inventory the fractures that need to be
targeted for sealing. A list of fractures will be prepared that itemizes each
fracture area and approximates the length, depth, and width of the fracture
that needs to be sealed. A map will be produced showing each fracture and
the existing habitat at each location. Total fracture volume can then be
estimated in order to develop an overall approach to the task and specify
the appropriate equipment and fracture sealant.
Several options will be evaluated for fracture sealing that include a variety
of equipment, materials, and methods. Various sealing media will be
considered such as fill soil, bentonite clay, or soil-cements. Sealant
delivery options are anticipated to include simple mixing and pumping as
well as mobile long-reach grout rigs. Each option will be presented as a
line item in a detailed table that presents a technology summary,
advantages, disadvantages, effectiveness, estimated longevity, costs, and
other factors, such as potential habitat impacts. The table of options will
be presented to the city and community for discussion and evaluation that
will ultimately lead to selecting the best option.
G. TASK E: City Council Meetings
Consultant’s anticipated agenda for each meeting:
1. Meeting 1: A preliminary draft schematic design for drainage and
dewatering will be presented to the City Council for review and approval
prior to proceeding beyond 30% design.
2. Meeting 2: A draft revised pre-construction design incorporating City
Council and City staff direction will be presented to the City Council for
further review and approval.
A-33
01203.0006/524815.6 A-13
3. Meeting 3: A final 100% construction-ready design will be presented to
the City Council. Consultant will prepare PowerPoint files for each
meeting for overhead presentation to the City Council and public meeting
attendees. Each PowerPoint presentation will summarize the completed
work to date and illustrate the proposed engineering options for review,
discussion, and approval. Consultant will prepare and distribute meeting
minutes highlighting action items.
H. TASK F. Public Outreach Meetings
Consultant has planned and budgeted for two community outreach meetings, if
desired by the City. The meetings are anticipated to be completed at important
design milestones. Consultant will receive public comments, including after the
30-day comment period, and prepare a response-to-comments (RTC) document to
form the basis for continued discussion and interaction with the community as
final designs are selected and approved. The City Council will review and approve
the RTC document. Two meetings are anticipated for this Project:
1. Meeting 1: Present and discuss draft proposed plans and receive and
discuss community feedback.
2. Meeting 2: Present and discuss final construction-ready design and receive
and discuss community feedback. Consultant will prepare electronic
presentations using Powerpoint for each meeting for overhead
presentation. Each presentation will summarize the completed work to-
date and illustrate the proposed draft and final engineering options for
review, discussion, and approval. Consultant will prepare and distribute
meeting minutes highlighting action items.
I. TASK G: Hydro Augers
1. Design of Hydro-Auger System – Conceptual. In addition to reduction of
infiltration, this task includes the following goals:
a. Reduce artesian pressures below the basal failure surface
b. Reduce steady-state seepage (groundwater flow).
Both goals will be achieved by designing and installing a system of
hydro-augers. The first set of hydro-augers will be advanced below
the postulated basal failure surface to relieve the artesian pressure
within the bottom portion of the slide. These hydro-augers will not
be significantly affected (i.e., sheared-off, as would likely happen
for conventional vertical pumping wells drilled through the base of
the landslide) by the current relatively large movement of the
sliding mass (presently, on the order of 8 ft/yr). Following the
initial mitigation stage to achieve artesian pressure relief and
A-34
01203.0006/524815.6 A-14
reduced infiltration, additional hydro-augers will be installed (with
penetration into the sliding mass) to lower the groundwater
elevation, reduce steady-state seepage forces, and improve the
redundancy and overall longer-term performance of the dewatering
system. To enhance drainage/relief of artesian water pressure, a
“casing perforating device” may be used. This device is a
perforating gun to provide effective flow communication between
a cased wellbore and formation water.
2. Design of Hydro-Auger System - Technical
Consultant’s preliminary design of the proposed hydro-auger system will
be based upon the existing information in the FS Update. However,
Consultant may propose supplemental subsurface investigation, if
Consultant finds that such information would fill needed data gaps and
benefit the project, (i.e., would reduce the number and length of hydro-
augers). This approach is further described in the “Value
Engineering/Monitoring Success” section of this task.
The proposed hydro-auger system will be designed based upon the results
of engineering evaluations, including 3-D seepage and slope stability
analyses. These engineering evaluations will build upon the previous work
by the Consultant that was conducted as a component of the FS Update, as
follows:
a. Expand the 3-D slope stability model (depicted in figure above)
with SVSLOPE (https://soilvision. com/product/svslope) of the site
to include additional areas affected by landsliding that require
mitigation or otherwise influence landsliding, as necessary. The
original 3-D slope stability was built as a component of the FS
Update
b. Refine and update the groundwater elevation surface based upon
the results of the Water Balance Study described above
c. Apply steady-state seepage and artesian pressure modeling options
to more accurately represent the observed phenomena using the
program SVFLUX which directly interacts with SVSLOPE
(https://soilvision.com/products/ svoffice-ge/svflux-ge). For the FS
Update, the 3-D slope stability model included only the manually-
entered, best estimate of the piezometric surface, and it only
indirectly considered artesian pressure
d. Calibrate the model with updated piezometric surface using output
from the Hydrology Analysis as available, steady-state seepage,
and artesian pressure to match the observed conditions (i.e., Factor
of Safety (FS) ? 1.0 (sliding); up to 8 feet per year of measured
A-35
01203.0006/524815.6 A-15
gross displacement) and validate the results using a 2D analysis of
a critical cross section)
e. Evaluate the effect of “low infiltration” (e.g., using the results of
the Water Balance, calculate how long will it take to increase FS to
1.25 and 1.5 and hence mitigate displacements
f. Evaluate the following parameters of the hydro-auger system: (i)
location of hydro-augers; (ii) number of hydro-augers; (iii) spatial
orientation of hydro-augers; (iv) length of hydro-augers; and (v)
diameter of hydro-augers. This evaluation will be an iterative
process that also includes cost and time considerations. As
discussed in the RFP, concurrence by the City will be sought for
each “critical” step of this process
Upon completion of Step 6, Consultant will develop an implementation
schedule (i.e., Gant Chart), design drawings, and technical specifications,
and will develop a bid package. Relevant calculations will be submitted
electronically (e.g., PDF) with the drawing and specification package, as
requested by the City. The constructability and standard detail
requirements will be developed in consultation with our proposed drilling
subcontractor, Directed Technologies Drilling (DTD).
Consultant will also evaluate vertical groundwater extraction wells in this
task. Vertical extraction wells are a traditional and effective groundwater
extraction technology where installed in appropriate subsurface conditions.
However, vertical wells in the Portuguese Bend landslide complex haven
proven to be problematic given continual slope failure and land
displacement. As a result, as discussed in the FS Update, vertical wells are
anticipated to be more cost-effective if installed later in the mitigation
program once some slope stability has been achieved with other means,
such as hydro-augers. A vertical wells plan, if appropriate, will include
design, placement, and cost estimates.
3. Value Engineering/Monitoring the Success
Consultant’s preliminary design of the proposed hydro-auger system will
be based upon existing information provided by the City. It will be
developed at a level suitable for development of a bid package.
Implementation of the hydro-auger installation will be designed to occur in
phases, as discussed in the FS Update. This will allow for review of
additional information gathered during each phase of installation, and
potential adjustment of the design (if it benefits the project). For example,
during the first phase of the implementation, hydro-auger boreholes will be
logged, sampled, and tested, and flow out of the holes will be recorded.
This is valuable information that will be processed, evaluated, and input
A-36
01203.0006/524815.6 A-16
into our 3-D model of the site. The model will be re-run, and the number
and length of hydro-augers might be adjusted accordingly.
Additional information that will benefit the project includes:
• Current (at the onset of the project/3-D modeling) information
on groundwater elevation, flow direction, and artesian pressure
along the basal failure surface
• Information on the basal shear surface (more accurate elevation
contours within the area affected by landsliding)
• Information on landslide movement (monument survey)
As discussed in the FS Update, information on file, for all three items
listed above, is (or will be) dated, and may not be accurate at the level that
would most benefit the project. Therefore, during the implementation
phase of this project, Consultant may propose to advance and instrument
up to three boreholes. The boreholes will be advanced within the bottom
third of the landslide mass and will extend beyond the postulated basal
failure surface. They will be instrumented with: (a) vibrating wire
piezometer; and (b) Time Domain Reflectometers (tilt meters).
Representative soil samples for laboratory testing (saturated hydraulic
conductivity below and above failure plane) will be recovered as well.
4. Cost-Benefit Analysis
Consultant will complete a cost-benefit analysis regarding hydro-
auger design, installation, and maintenance compared to the
ongoing maintenance cost associated with maintaining Palos
Verdes Drive South. The cost/benefit analysis will compare the
routine costs and benefits of periodic roadway assessment and
repair with the key issues related to the advantages and potential
disadvantages of hydro-augers including long-term and short-term
costs, slope stability, and short-term and long-term benefits. The
analysis will consist of a series of order-of-magnitude costing
tables and a summary table summarizing and scoring the pros and
cons of each option. Given the compromised nature of the current
roadway, the analysis would not be complete without considering
complete roadway collapse and repair due to an episodic slope
failure event. Consultant’s cost-benefit analysis will also consider
this scenario.
J. TASK H: Utility Coordination
Consultant will contact and coordinate with the appropriate public utilities
to ensure that utility lines and infrastructure are fully identified and
A-37
01203.0006/524815.6 A-17
protected during upcoming design planning for construction work.
Consultant has already identified several utility line locations during
property area site walks and using the City GIS layers.
Sewer lines, storm lines, and potable water lines in the landslide complex
are already input to the GIS system that Consultant prepared for the FS
Update and are ready for use during design document preparation.
K. TASK I: Prepare construction plans
Based on the results of our engineering evaluations, Consultant will prepare a set
of full-size construction plans (scaled 22 inches x 34 inches) for the proposed
remedial measures. Key features to be included in the construction plan
correspond to the expanded sheet titles, as outlined below:
1. Title sheet, showing site vicinity map
2. Construction notes sheet
3. Existing conditions, including site topography, existing utilities, and
pertinent site features, such as channel alignments, and fractures
4. Drainage plan showing limits of lined channel installation and fracture
infilling (i.e., fracture locations and planned equipment layout)
5. Groundwater extraction plan, showing tentative hydro-auger installation
plan and section views as well as locations of vertical extraction wells, if
any, included in the design; hydro-auger installation plan will show entry
and exit pit locations, diameter, alignment, and confirmatory geotechnical
borings for the proposed drains; Drains to be installed first (the first phase)
will be clearly labelled
6. Monitoring plan showing locations of instrumentation for evaluating
effectiveness of the remedial measures; instrumentation will include
existing and proposed survey control points, TDRs, and vibrating wire
piezometers
7. Erosion control plan, showing locations and types of temporary (i.e., in-
place during construction and, potentially, removed at the end of
construction) and permanent (i.e., to remain post-construction) erosion
control BMPs
8. Grading plan for provision of laydown areas, equipment access, and
working platforms for installation of remedial measures
9. Detail sheets for surface water and erosion control, including fracture infi
lling, geosynthetics design for channel lining, and temporary and
permanent erosion control BMPs
A-38
01203.0006/524815.6 A-18
10. Detail sheets for the first phase of hydro-auger installation and
development
11. Detail sheets for the first phase instrumentation design and installation
12. Construction plans will be submitted to the City in electronic (AutoCAD)
format for review and comment at the 30%, 60%, and 90% design
completion stages. At the 30% design stage, Consultant will also perform
internal peer review of the designs for constructability of the proposed
features. Consultant will incorporate City comments and deliver an
electronic copy of the bid-ready plan set at the 100% design stage.
L. TASK K. Prepare Engineer’s Estimate
Consultant will develop an engineer’s estimate for the proposed remedial work
during preparation of the 60% design construction plans, including construction
quantities and construction quality assurance program costs. This will be an order-
of-magnitude cost estimate for planning purposes and will be developed based on
a combination of Consultant in-house cost data for recent similar construction
projects, publicly available data (e.g., Caltrans, FHWA), and discussions with the
Consultant team subcontractors.
M. TASK L. Prepare technical specifications and applicable special provisions
1. At the 30% completion stage, Consultant will outline Technical
Specifications and will complete their development at 90% design stage.
Work will also include construction quality control guidance for the
proposed remedial work. Key features to be addressed in our specifications
package include:
a. Geosynthetics material and installation guidance for channel lining
b. Material type and delivery method for fracture infill
c. Pipe material and installation method for horizontal drainage
d. Drilling fluid management for directional drilling
e. Instrumentation installation and monitoring procedures
f. Earthworks for incidental grading
g. Applicable APWA Green Book guidance
h. Erosion control measures, including typical BMPs, guidance based
on NPDES permit requirements, and guidance based on provisions
of the Clean Water Act
A-39
01203.0006/524815.6 A-19
i. Recommended inspection and maintenance regimen for hydro-
augers, channel lining, and fracture infill
2. Per City requirements, technical specifications will be submitted in hard
copy and electronic formats. At the 90% completion stage, Technical
Specifications will be provided in electronic format (Microsoft Word).
Revised specifications will be submitted in hard copy and electronic
formats at the 100% design stage.
N. TASK M. Prepare Bid Document Package
Upon the City’s acceptance of the 100% design stage plans and specifications,
Consultant will provide support to the City for development of a bid package. The
City will provide an example Bid Document Package and will provide front-end
Technical Specifications (including the format for the Notice to Bidders, Table of
Contents, General Provisions, Special Provisions, and format for Bid and Contract
sections). Consultant will develop Special Provisions by combining project-
specific special provisions with the City’s Special Provisions. Project Plan Sheets
will be referenced in the Bid Documents as an attachment. The assembled Bid
Document Package will be provided to the City in electronic format (i.e., PDF,
Microsoft Word, and AutoCAD, as appropriate).
O. TASK N: Attend meetings and answer RFIs
For this task, Consultant will be available to attend monthly meetings with the
City and the Ad-hoc Committee during design plan preparation to provide project
activity updates and to receive and discuss City input, review, and comment.
Consultant will also attend meetings at the City offices during the pre-bid and pre-
construction phases of the project to coordinate with the City staff and prospective
bidders regarding bid questions, clarifications, and requirements. Consultant will
respond to Requests for Information (RFIs) during the bidding and construction
phases of the project as needed. A total of four (4) meetings at the City are
estimated for this task.
P. TASK O: Final Deliverables & As-Builts
Consultant’s deliverable for the pre-bid phase will include bid-ready plans,
specifications, and a bid package provided to the City in hard copy and electronic
formats, as applicable. At the end of the construction, (i.e., in the implementation
phase, not as a part of this design-phase scope of work), Consultant will
commission an “As-Built” survey of the constructed improvements and submit
full-size (i.e., 22 inches x 34 inches) drawings electronically in AutoCAD and
PDF formats.
Q. TASK P: Estimated Construction Project Schedule
A-40
01203.0006/524815.6 A-20
Consultant will prepare an itemized overall project construction schedule as part
of the overall deliverables. The schedule will be built in MS Project and converted
to a suitable format for the City if needed such as pdf. The draft schedule will be
reviewed by City staff and comment will be incorporated into the draft before a
final schedule is prepared.
R. TASK Q: Project Surveying
DBS&A has teamed with McGee Surveying Consulting for this task. After
incorporating earlier surveys that started in 1994, McGee Surveying has
completed the City’s annual GPS surveys of the landslide complex monuments
since 2007 to document land movement on an annual basis in the Portuguese
Bend area. The annual McGee Surveying reports form the basis for quantification
of overall land displacement and definition of the “Red Zone” area of greatest
land movement in the landslide complex. Consultant and McGee Surveying will

I. INTRODUCTION
The City of Rancho Palos Verdes is a scenic, upscale, residential coastal community,
with a population of approximately 42,000, located on the Palos Verdes Peninsula of
southwestern Los Angeles County.
The City of Rancho Palos Verdes is a contract city, meaning that some services are
provided by contract with agencies (both public and private) and some services are
delivered by the City’s own employees.
City Government: Rancho Palos Verdes is a General Law City and has operated under
the Council-Manager form of government since its incorporation in 1973. Policy-making
and legislative authority are vested in the governing City Council, which consists of five
Council Members, including the Mayor and Mayor Pro-Tem. The City is fiscally sound and
functions on an annual budget cycle.
II. PROJECT OBJECTIVE
The Portuguese Bend Landslide began moving in 1956, several studies have been
performed including the most recent Update to the Portuguese Bend Landslide
Feasibility Study. Details and history of the project should be viewed at
http://www.rpvca.gov/documentcenter/view/12275.
The City is seeking proposals that incorporate both Phase 1 and Phase 2 into one
consolidated proposal. The successful firm will provide Engineering Analysis and Design
Services for the City’s Portuguese Bend Landslide Mitigation Project, Phase I. The City

III BACKGROUND: UPDATE TO THE PORTUGUESE BEND LANDSLIDE
FEASIBILITY STUDY
The City of Rancho Palos Verdes Department of Public Works provides infrastructure
management to all aspects of public facilities which are funded by the General Fund,
Capital Improvement Fund etc.
The Portuguese Bend Landslide is located within a larger landslide complex between
the Abalone Cove and Klondike Landslides. The Updated Feasibility Study (FS)
incorporated environmental, engineering, and hydro geologic work completed to
address regional slope failure on the greater Palos Verdes Peninsula. The FS was an
update of the efforts completed primarily in 1997 and 2000 that characterized the hydro
geologic and geotechnical conditions driving landslide activity and proposed a variety of
various approaches and technologies to abate slope failure in the Portuguese Bend
Landslide Complex.
The City hired Daniel B. Stephens & Associated, Inc. (DBS) to include public outreach
and generate the FS. Following extensive public outreach, the City Council accepted the
FS which is available and should be viewed at
http://www.rpvca.gov/documentcenter/view/12275. The FS included preferred technology
options that are to be further evaluated and if appropriate, designed through this project:
• Directional Subsurface Drains
• Flexible Liner System and Components
• Groundwater Extraction Wells
• Drainage system under Palos Verdes Drive South to the ocean
The FS was vetted through a public process as the draft FS was being developed. The
draft FS was presented to the City Council. Public comments received following that
meeting were reviewed, answered and incorporated into the final FS. Environmental
considerations specific to engineering solutions were made known during the City Council
meetings and are to be given full consideration during any proposed solutions designed
during this process. Specifically any lining within the canyons that is determined to be
required are to be limited to the lower reaches of the canyons and placement of lining
materials shall be reviewed with Staff, the council and the public to fully disclose where
and how material would be installed.

Mr. Elias Sassoon Director of Public Works City of Rancho Palos Verdes 30940 Hawthorne Boulevard Rancho Palos Verdes, California 90275 Re: Executive Summary for Engineering Analysis, Evaluation, and Design for Portuguese Bend Landslide Drainage and Dewatering (Hydro-auger) Proposal Dear Mr. Sassoon: Daniel B. Stephens & Associates, Inc. (DBS&A), a wholly owned subsidiary of Geo-Logic Associates, Inc. (GLA), is ready to continue providing technical support to the City of Rancho Palos Verdes (City) in their efforts to stabilize the Portuguese Bend landslide complex.
Approach to Statement of Work Building on the results of our recently completed mitigation Feasibility Study Update (FS Update), our team’s geotechnical, engineering geology, hydrogeology, and civil design experts will move the program forward quickly and efficiently using innovative, yet proven mitigation solutions. Our team is already well up-to-speed, having recently reviewed and studied the relevant site and site history data and completed the FS Update — we can immediately begin working on the remedy. We have also developed an effective working relationship with City staff and the engaged community stakeholders. Our previous stakeholder engagements were well received, our proposed mitigation measures have been thoroughly discussed with all of the stakeholders, and we have been acknowledged for our collaborative nature and ability to balance sensitive ecological and engineering construction issues. The main cause of landsliding at this site is a combination of hydrogeological and geotechnical factors, including the presence of low-strength materials along existing slide planes (i.e., basal failure plane(s)) and the presence and flow of groundwater. The hydrogeologic (i.e., groundwater) conditions within the Portuguese Bend landslide are complex. They include not only steady-state seepage within the sliding mass, but also artesian pressure. There is significant recharge that maintains the steady-state conditions, and, likely, also maintains the artesian pressure along the basal failure surface. Based upon our understanding of site geological and hydrogeological conditions, and project constraints, our geotechnical engineering and engineering geology experts developed a three-dimensional (3D) numerical model of the Portuguese Bend landslide complex. This recently completed effort will uniquely enable us to move forward and further improve the model to evaluate drainage, dewatering, and pressure relief options using state-of-the art analytical methodology. The work will be performed in a sequential, phased approach as outlined in the FS Update. We will use the updated, improved, calibrated, and validated model to evaluate various hydro-auger dewatering options, including location, orientation, length, diameter, and rate of dewatering. The updated model will guide us in identifying monitoring approaches to track the
C-4
Mr. Elias Sassoon November 9, 2018 Page 2
progress of landslide mitigation and, upon the City’s approval, facilitate detailed design and construction planning. The hydro-auger design would not be complete without hydrological evaluations. Therefore, our hydrology and hydrogeology experts will complete a Hydrology Analysis and optimized Water Balance to gather the input needed for drainage and dewatering design as well as future FS tasks, such as quantifying leach field recharge to groundwater. As specified in the RFP, a detailed hydro-auger cost/benefit analysis will also be integrated into our design planning and stakeholder review process. We understand the upper reaches of Portuguese, Ishibashi, and Paintbrush canyons include established, sensitive habitat. The Hydrology Analysis will, in part, help assess the degree to which these critical areas contribute to groundwater recharge in the “Red Zone” area of greatest identified land displacement. Even if the upper canyons are shown to significantly contribute to groundwater recharge in the Red Zone area of greatest identified land displacement (as outlined in the FS Update), our geotechnical model will allow us to evaluate engineering options to minimize subsurface dewatering and reduce or eliminate upper canyon work. We will also optimize fracture sealing (in-filling) in the slide head scarp area to reduce surface water recharge to groundwater while preserving habitat areas. We will balance our proposed work with local utilities and the requirements of the California Environmental Quality Act (CEQA) by seeking to minimize or eliminate potential impacts related to construction, operation, and maintenance of the final design. Our proposed work will adhere to Clean Water Act and National Pollution Discharge Elimination System (NPDES) permitting requirements, and will meet American Public Works Association (APWA) “green book” of plan and specification standards. We routinely produce construction plans, technical specifications, engineer’s estimates, and bid packages for a variety of engineering projects. The City will benefit from our extensive experience in developing bid package drawings and deliverables from initial concept to contractor and City bid question-and-answer assistance. We will take a lead role, with City coordination, in conducting contractor pre-bid and pre-construction meetings, and addressing Requests For Information (RFI) during bid package review. DBS&A maintains a thorough and active project management and quality control/quality assurance (QA/QC) program for every project and deliverable, which is led by our Senior Principals. Critical pre-deliverable internal review is an essential component of our work product delivery process. Not only are overall project concepts carefully reviewed to stay on scope, on budget, and on schedule, but the fine details of our work are reviewed to ensure work is of high quality, defensible, and accurate. We will stay in close contact with the City and community stakeholders during preliminary, draft, and final design and deliverable preparation through City Council meetings, public outreach meetings, monthly project meetings, and monthly City website updates.

RE: Portuguese Bend Landslide – Directional Drilling
Dear John:
DTD is pleased to present our qualifications to join the team you are assembling to prepare engineering
analyses and design for landslide control and mitigation work at the Portuguese Bend landfill site for the
City of Rancho Palos Verdes. DTD is highly qualified to work with your team to provide specific
expertise in the field of directional drilling.
Our firm was founded in 1996 by former consultants in the environmental and geotechnical fields. Our
business model has been and remains to provide high quality directional drilling services, lead by earth
scientists, with degreed field supervisors directing the project in the field. This approach has been highly
successful, in that our team not only understands the mechanics and art of drilling but has a full
understanding of our client’s purpose and intent in completing the project. As a result, our approach
streamlines the project and our deep interaction with our clients enables the team to anticipate many of
the potential challenges during the planning stages, in advance of mobilization to the field.
In our view, this is one of the key factors that separates DTD from our competitors. Of particular
importance in the proposed phase of work for the City will be our knowledge of the intricacies of
directional drilling in this geological setting. For example, key issues may include drill tooling and
drilling fluid selection in bentonite/montmorillonite clay and weathered ash, strategies for mud rotary
directional drilling along the slip plane of an active translational landslide, the mitigation of potential
fines piping or slope raveling issues at the exit end of the bore, and prevention of potential blowout risks
at the bore terminus during drilling. Our team’s experience in geologic consulting, combined with our in-
depth directional drilling knowledge, offers the DB Stephens / Geo-Logic team a valuable asset. In
addition to this expertise, DTD has worked with DB Stephens on several projects in the recent past,
demonstrating our problem-solving approach and ability to work with you to achieve project objectives.

review, such as review of
proposed equipment and
materials, planning/scheduling, will be provided
by Directed Technologies Drilling, Inc. (DTD). DTD is
a national leader in horizontal, variable angle, and
directional drilling and drain installation for a
variety of geotechnical applications such as slope
stability and groundwater dewatering. The DBS&A
team and DTD have collaborated on other
successful horizontal drain projects. Past DTD
clients say, “They are very professional and do
great work. I would never even consider using
anyone else for horizontal well work. We have
plans to use them again on two different
remediation projects.” DTD has the heavy
equipment, materials, field crew leaders, and
unique experience needed to provide the
innovative leadership and specialty knowledge
that will be required to prepare for sub-horizontal
drain drilling and installation in an area as large, as
active, and as complicated as the Portuguese Bend
landslide complex. Specifically, based upon
engineering input from the DBS&A team, including
project- and location-specific requirements, DTD
will:
Select drilling method/equipment
Develop a directionality plan (how to reach
required locations from a given drilling point)
Evaluate access (where drain drilling work areas
can and need to be located)
Assist with cost-benefit analysis (what size/
diameter drain pair is the most cost-efficient and
practical)

Experience
The DBS&A team has demonstrated exceptional
technical competence with specialization in
projects similar in scope and complexity to the
proposed project in the ongoing and recent
projects listed below. DBS&A worked with the City
of Rancho Palos Verdes to prepare the FS Update
for the Portuguese Bend landslide complex in
2018. The FS Update recommended stormwater
control to prevent continual hydraulic loading
to key areas in the slide subsurface, subsurface
groundwater dewatering, and surface fracture
in-filling to significantly reduce regional slope
failure and mass landsliding over time. DBS&A
recommended supplementing stormwater control
with groundwater extraction as a proven method
for effectively controlling slope failure. Proposed
solutions will be integrated into habitat restoration
and maintenance areas outlined in the Natural
Communities Conservation Plan (NCCP) Habitat
Conservation Plan (HCP).
Our team’s involvement in the FS Update puts us
in a unique position to expedite implementation
of a design remedy. This project and others that
demonstrate our team’s technical competence and
specialization necessary for the next phase of the
project are briefly summarized below. Detailed
descriptions of these projects are located in

Multiple, Remote Remediation Well Installations, Galena, Alaska
In 2017, DTD completed a $3.3M project to install
a total of eight wells at the Galena Air Station in
Alaska. The wells ranged from 800 to 1,200 feet
in length. A key challenge in this project was the
remote location, which required a large drill rig,
support equipment, supplies, parts and crew
to be mobilized by air, ocean barge, overland,
and river barge for 300 miles to the site in the
Alaskan interior. The wells were drilled, installed
and developed sequentially in the brief open
window for river navigation from ice breakup in
late May, demobilizing before the river froze again
in September. The remote location required a
high level of self-reliance on the part of the crew,
since the logistics chain for parts and materials
was long, weather dependent, and unreliable.
DTD successfully completed the project on time,
installing nearly 8,000 feet of wells.

than 30 years of relevant project experience. He is
a Washington State licensed geologist, #2797. He
received a B.S. in geology from Southern Oregon
State College in 1979. As a DTD staff member,
he holds five U.S. patents for various drilling
techniques and/or systems.
James Ditto is Senior Drilling Supervisor at DTD.
He has more than 30 years of equipment operation
and HDD project participation experience. Mr.
Ditto has been instrumental in the development
and implementation of numerous DTD innovations
in horizontal wells, including several patented or
patent-pending inventions. He mentors junior
staff in the means and methods necessary to
successfully install horizontal wells, has developed
tooling and protocols for drilling methods using
our Knock Off well installation method, and has
designed and directed the manufacture of much
of the tooling used on DTD’s more exotic well
installations.
Experience
In addition to standard HDD contracting services
to install remediation wells at small to medium
sized projects, DTD has teamed with top
companies in the environmental and engineering
fields on several notable projects within the past
five years. These projects demonstrate DTD’s
abilities to work closely with consultants to
devise innovative solutions and to solve complex
logistical challenges in order to achieve project
goals. Project examples include the following:
Horizontal Well Drilling for Santa Fe County
Judicial Complex Remediation, Santa Fe, New
Mexico
DTD worked closely with DBS&A on a unique
horizontal well installation project in New Mexico.
Due to site limitations, the only feasible method
to access targeted groundwater was to install
horizontal wells underneath existing structures.
Per DBS&A’s design specs, DTD initiated drilling

and surrounding properties. As a consequence
of these access restrictions, DTD proposed the
installation of two wells, each more than 2,500 feet
in length. DTD employed proprietary and patented
drilling methods to install the long, double-ended
wells in unstable, non-cohesive soils which would
have collapsed if open-bore techniques were used.

Shallow Industrial Water Supply, Earth, Texas
To meet the increasing industrial water demands
for a remote power plant in central Texas, Xcel
Energy turned to DTD to assist with designing
and installing horizontal wells to tap the shallow
regional aquifer. Drawdown from vertical wells
in this thin aquifer was making it increasingly
difficult to sustain the flow rates necessary to
supply required water volume. DTD worked with
the project designers to refine a feasible well
configuration and then worked with well screen
manufacturers to perfect a new type of stainless-
steel well screen that would support high flow
and still survive the installation stresses unique
to HDD wells. The well, installed in 2017, is 2,300
feet in length and 190 feet deep. It is constructed
of 12-inch diameter carbon steel risers, with 500
feet of the specialized well screen. The project took
approximately 10 weeks to complete, including an
extensive well development program. The tested
output of the well at the completion of the project
was over 1,000 gpm, far exceeding the target
750 gpm, far exceeding the production of nearby
vertical wells. Completion date: 2017
Extended Length Groundwater Wells, Ft. Valley, Georgia
A sizable petroleum release from a pipeline

Pepperdine University Campus Life Project Development
Envicom Corporation prepared CEQA compliance
documents on behalf of the Pepperdine
University’s Campus Life Project (CLP) located
at Pepperdine’s Malibu Campus. The proposed
project provided a variety of land uses involving
redevelopment and relocation of land uses and
buildings within the campus. Proposed uses
included athletic, recreation, entertainment,
parking, and residential facilities. The CLP
included six components and entailed both the
construction of new facilities and the renovation
of existing structures. The six components were:
(1) student housing rehabilitation, (2) athletics
and events center, (3) upgraded NCAA soccer field,
(4) Town Square, (5) enhanced recreation area,
and (6) parking structures. The CLP was designed
to enhance campus life, support educational
activities on campus, provide enhanced public
benefits, update aging buildings, increase the
ability to remain competitive in prospective
student recruiting efforts, and provide necessary
support facilities. Environmental issues that
were addressed in the EIR include geotechnical
hazards, hydrology and water quality, fire hazards,
noise, biota, visual qualities, traffic and access,
and other key areas. The proposed project,
located within the Coastal Zone between the
Santa Monica Mountains and the Pacific Ocean,
required amendments to Pepperdine’s Long-

C. WORK PLAN
The remedies outlined in the FS Update included hydro-auger installation,
canyon liners, fracture sealing, and stormwater control in the lower
Portuguese Bend landslide complex north of Palos Verdes Drive South. The
DBS&A team understands that the City and community stakeholders want
to implement the remedies outlined in the FS Update in a “phased” manner.
The objective of a “phased” approach is to validate that the installation
methodologies, construction materials, critical design parameters, and
impact on critical habitat are appropriate before proceeding to later stages
of full-scale construction and cost expenditure. Therefore, our scope of work
includes development of design plans, specifications, and a bid package as
the first phase of each remedy element. This section presents our approach
to creating final designs and implementing the remedies identified in the FS
Update. Our work plan to execute the proposed scope of work is provided in
detail in the following sections.
We propose to implement a work-breakdown structure (WBS) process that
allows for early City review and appropriate stakeholder input regarding
task sequencing, level-of-effort, and deliverables. A preliminary WBS will be
prepared listing the major and minor project tasks in chronological order
with a simplifying description of the major task elements. This WBS list will
serve as the basis for initial discussion and planning in the project kick-
off meeting. (For example, the components of the hydrology study will be
outlined in the draft WBS to gain consensus before moving forward.) Once
final, it will provide the overall structure for project elements and project
schedule through project completion. The WBS will also serve as the basis
for tracking work task completion, financial accounting, invoicing, and
budget expenditure. We have prepared a preliminary project schedule using
Microsoft Project software on the following page.
The schedule shows the major task elements in sequence with start dates,
durations, and end dates. This schedule will be updated as the project tasks
are sequentially completed. We understand the City has estimated project
completion by September 2019 with construction starting in Spring 2020 and
we have developed our schedule to meet this goal.

Engineering Analysis, Evaluation, and Design for Portuguese Bend Landslide Drainage and Dewatering (Hydro-augers)
DESIGN SERVICES
A. Project kick-off meeting
Key members of the DBS&A project team will
meet with City staff to outline the drainage and
dewatering design project in detail before major
tasks commence. DBS&A will present our proposed
WBS (discussed above) and project schedule
along with a summary of the major tasks and our
approach to each task and subtask. The lines of
communication between team members, the
City and community, and other stakeholders will
also be discussed. Data needs from the City and
major deliverables will be outlined in order to
achieve a common understanding regarding the
overall project as well as proposed methodologies,
engineering technologies, and dewatering/
drainage and landslide mitigation goals.
B. Review Existing Records/Field
Inventory
Past reports, maps, data sets, and work products
from previous efforts to understand and stabilize
the Portuguese Bend landslide are critical to
moving forward in a cost-effective manner
without duplicating past investigation work
or partial abatement efforts. DBS&A is already
exceptionally familiar with existing records, maps,
meeting notes, and other related documents from
our past work. DBS&A previously compiled 525
reports, maps, data files, photographs, and related
documents for the City during FS preparation in
2017 and 2018 totaling 5.5 gigabytes of electronic
storage space. We also developed a geographic
information system (GIS) using key data and
map layers that allows for the simple graphical
presentation of complex information and data
using ESRI ArcGIS software. Existing ArcGIS layers
representing City infrastructure and landslide
information were provided by the City and
imported into our GIS.
DBS&A has observed that substantial stormwater
ponding and associated subsurface infiltration
to groundwater is occurring in the Red Zone
area adjacent to the northern side of Palos Drive
south. In this area, lateral land displacement is
nearly 8 feet per year. As a result, the land surface
near the stormwater culvert under the road has
subsided such that the land surface elevation is no
longer high enough to match the culvert intake
to allow flow under the road to the ocean. These
issues should be addressed as soon as practicable
to reduce further damage. Our scope of work,
therefore, includes development of design plans
for an initial phase of stormwater control in this
area. Full-scale construction of a stormwater
control remedy in this area, such as full area re-
grading and installation of a stormwater liner
system throughout the Red Zone area, may best
be installed later, after lateral land displacement is
reduced through other means (i.e., hydro-augers).
As stated above, construction for the drainage and
dewatering tasks will be completed using a phased
approach to evaluate if specified designs can be
constructed and will function as designed before
moving into the later stages of work over large
acreage. Any specified field construction will be
thoroughly reviewed and approved in advance by
the City and community. Work will be specified in
compliance with the NCCP/HCP.
As discussed with the City and community
stakeholders, any lining within the canyons that
is determined to be required will be limited to
the lower reaches of the canyons and placement
of lining materials will be reviewed in detail with
Staff, City council, and the public to fully disclose
where and how materials would be installed.
Field Inventory
DBS&A has addressed the field inventory as part
of Task B - Review Existing Records, under Design
Services below.

Numerous paper documents were scanned into
electronic format for the first time for distribution
to the City and for permanent record preservation
over the long term. The GIS system and the
entire project library archive are available in city-
compatible ArcGIS, portable document format
(pdf), or Microsoft Office format for project use.
GIS files are also compatible with Google Earth for
easy display using any web browser. At this time,
the GIS and electronic document archive is the
most comprehensive public information repository
in existence related to previous work reported
for the Portuguese Bend landslide complex. Key
reports, research papers, and available datasets
are systematically organized by date, author,
and subject matter. This document archive and
GIS mapping tool will serve as the technical and
management basis moving forward in the overall
program to help stabilize the landslide complex.
The DBS&A team has already comprehensively
reviewed the key reports in the document library
during document compilation and review during
FS preparation. The key documents and data will
be further incorporated into new work as needed
in our planning and design tasks to be completed
for the proposed scope of work. As a result of
FS Update development, we are pleased that
the DBS&A team’s work for this proposal task is
essentially already completed.
As a result, we can move quickly into the design
phase of the work with minimal cost and time
allocated to records review. The DBS&A team will
work with City staff to further identify any
additional documents to add to the library as
needed.
DBS&A completed the FS Update that forms the basis
for the drainage control and dewatering design for the
Portuguese Bend landslide.
DBS&A developed a comprehensive GIS mapping
system in 2018 during a review of existing historical
records completed for the FS update. GIS will be used
during the design stage for drainage and dewatering of
the Portuguese Bend landslide.

Critical field data will need to be collected in order
to perform an accurate and meaningful Water
Balance to support project design. Therefore,
the Hydrologic Analysis will include field data

conveyances will be visually surveyed to evaluate
their current location, condition and current
ability to transmit estimated peak streamflow.
Groundwater well inspection survey.
Information provided by the City of Rancho
Palos Verdes indicates that up to 20 dewatering
wells have been constructed and installed within
the Hydrologic Analysis Area during previous
mitigation efforts. Except for four recent wells
installed in 2016, no information could be
located that documents the well construction
details, purpose of each well (monitoring or
dewatering), date of installation, well temporal
monitoring data, or the current status of the well,
and the FS Update recognized this limitation as a
data gap that should be aggressively addressed
moving forward. DBS&A will perform a well
inspection survey of wells in the Hydrologic
Analysis Area, including, as appropriate, down-
hole video surveys and measurement of depth-
to-groundwater, wellhead elevation, well depth
and diameter, and well screened interval.
DBS&A will also perform limited aquifer testing
of existing wells (e.g., slug tests) as a basis for
estimating hydraulic aquifer properties.
Irrigation Practices Survey. Within the
Hydrologic Analysis Area, landscape irrigation
occurs within the Rolling Hills neighborhood
and adjacent City neighborhoods as well as
within the Preserve. DBS&A will perform a visual
field survey of landscape irrigation practices,
including irrigated areas, landscape vegetation
(e.g., turf versus ornamentals), irrigation system,
and the presence or absence of overspray runoff
to impervious surfaces that results in irrigation
water flow to the stormwater system. The
irrigation practices survey will serve as a basis for
irrigation rate estimation for the water balance,
described below. DBS&A assumes that site access
for Rolling Hills will be obtained by the City.
Task C1. Field Data Collection
Field data collection will consist of the following
activities:
Streambed survey. DBS&A will conduct a field
survey for the streambeds in Portuguese Canyon,
Ishibashi Canyon, and Paintbrush Canyon and
associated tributaries (“the Canyons”). The
purpose of the field survey is to identify areas
of flat or impounded topography where surface
water may be subject to enhanced infiltration
and groundwater recharge and to characterize
other properties of the streambeds that govern
groundwater recharge. For example, preliminary
DBS&A field inspections conducted for the FS
indicated that there is a bermed area along
Portuguese Canyon just upslope of Burma Road
that likely impounds water, thus facilitating
infiltration.
Synoptic streamflow discharge survey.
Following a wet-weather event, DBS&A will
collect streamflow discharge data at several
locations along the Canyons. This data will be
used to identify sections of the Canyons where
streamflow may recharge to groundwater and
to estimate groundwater recharge. If flow in the
measured reach of the stream has decreased
from upstream to downstream, the decrease
may be attributed to streamflow recharging
groundwater. This type of survey is commonly
referred to as a “seepage run.” Field methods will
be consistent with U.S. Geological Survey (USGS)
techniques and will utilize staff gauges and
volumetric gauges (Rosenberry and LaBaugh,
2008). The timing of the utility of this task is
contingent on a suitable wet-weather event
occurring during the project period.
Surface water conveyance survey. Stormwater
flowing through the Canyons is currently routed
to the Pacific Ocean through an existing storm
drain network constructed in the Red Zone
area (figure shown on next page). The surface

of greatest land movement within the Portuguese
Landslide Complex (“Red Zone ”) (figure below)
to identify significant sources of groundwater
recharge and support design of the dewatering
system.

Engineering Analysis, Evaluation, and Design for Portuguese Bend Landslide Drainage and Dewatering (Hydro-augers)
The Nevada State Engineer has accepted the
DPWM as the most technically rigorous method
for groundwater recharge estimation during a
Nevada water rights hearing.
The DPWM computes at a grid scale, the water
budget components of recharge, evaporation,
transpiration, runoff, and soil-water storage
based on the unique combination of climate, soil,
vegetation and bedrock properties at the grid
cell location. Rather than a lumped estimate of
recharge for a watershed, the model produces
output that can map the location and quantity of
recharge within the basin. The DPWM recharge
map will be used to direct stormwater control
efforts.
Over the course of several previous projects,
DBS&A staff have streamlined application of the
DPWM, including data acquisition from several
different regional and national databases. Use
of the DPWM will, therefore, maximize project
efficiency and control costs. In addition to
groundwater recharge, DPWM also estimates
overland runoff, and will be used to estimate
peak stormwater runoff for design engineering
tasks described below. The hydrologic and
mathematical basis for the algorithms in
DPWM are drawn from peer-reviewed scientific
literature, are fully documented, and the code
and documentation are fully available to the
public. DBS&A has used the DPWM model
to evaluate the water balance in numerous
California watersheds.
Parameterization of the DPWM will be completed
with publically available data and data collected
in Task C1. The widely-used Parameter-elevation
Regressions on Independent Slopes Model
(PRISM) will be used to generate precipitation
rates that account for orographic effects on a
daily time step. Additional climactic data (e.g.,
wind speed, temperature) will be accessed from
local meteorological stations. Vegetation data
will be obtained from the USGS Gap Analysis
The Water Balance will consist of the following
components:
Aquifer characterization and groundwater
flow assessment. Groundwater flow direction
and volumetric flux will be estimated based on
the areal extent, thickness, and other physical
characteristics of the shallow aquifer underlying
the Red Zone area and canyons. To support this
analysis, a groundwater elevation map will be
developed for the Hydrologic Analysis Area, and
cross-sections presented in the FS Appendix C
will be updated to project groundwater elevation
throughout the upper Canyon areas.
Groundwater data will be obtained from data
collected under Task C1, from previous studies
as summarized in the FS Update, and if available
from the California Statewide Groundwater
Elevation Monitoring (CASGEM) Program and
State Water Resources Control Board GeoTracker
website.
Groundwater elevation maps will be used to
generate contours of groundwater elevation
and resulting estimated horizontal flow paths.
Groundwater underflow into the Red Zone and
groundwater outflow to the Pacific Ocean will be
estimated.
Watershed modeling/groundwater recharge
from precipitation and irrigation. Groundwater
recharge by precipitation occurs aerially
throughout the Hydrologic Analysis Area, and
is also focused within sections of the streams
during wet-weather flow. DBS&A proposes
to apply a cost-effective watershed model
to identify areas of significant recharge to
groundwater from precipitation and irrigation.
DBS&A developed the innovative Distributed
Parameter Watershed Model (DPWM) for this
purpose, and has significant experience in
applying this model throughout Southern
California, including in central Orange County,
Ventura County, Big Bear, Inyo County, and Santa
Barbara County, and throughout the southwest.

the onset of land movement. Newly collected
groundwater level data under Task C1, above,
will be compared to historical groundwater-level
data reported in the FS to estimate the change in
groundwater storage over time.
Identification of Key Sources of Groundwater.
Significant sources of groundwater recharge to
the Red Zone will be determined from the results
of the Water Balance. Groundwater recharge
from all sources (e.g., irrigation, septic systems,
precipitation) will be summarized in table and
graphical form. The results of the Water Balance
will be used to provide input on mitigation
measures to reduce groundwater recharge.
In addition, DPWM will be used to support
engineering design of the system dewatering
components.
Suggested Additional Tasks
DBS&A has identified several additional tasks that
we recommend be completed to gain a more
quantitative and complete understanding of
groundwater recharge sources driving elevated
groundwater and land movement to support
landslide mitigation. We recommend the City
consider adding the following tasks, contingent on
securing sufficient funding:
Streambed hydraulic measurements.
Streambed infiltration is controlled by the
thickness and hydraulic properties of streambed
sediments. Following the initial survey in Task CI,
we recommend streambed sediment thickness
and hydraulic conductivity be measured at
select locations identified as potential enhanced
groundwater recharge areas. Sediment thickness
and properties would be characterized by use
of a portable soil auger and/or drive probe, and
hydraulic conductivity would be measured with a
Guelph permeameter (see e.g., Batlle-Aguliar and
Cook, 2012).
Groundwater piezometer installation.
DBS&A recommends installation of two to four
piezometers in areas of the upper canyons in
Program (GAP), and soils data will be obtained
from the USDA Soil Survey Geographic (SSURGO)
and State Soil Geographic (STATSGO) databases.
Irrigation rates will be estimated based on water-
delivery records (if available), the irrigation
practices survey conducted under Task C1,
and literature references for irrigation rates in
Southern California (e.g., Costello and Jones,
2014). Irrigated areas will be estimated based
on the irrigation practices survey and review of
aerial photography.
DPWM results will be documented in a series
of maps and diagrams that document model
input data (e.g., topography, soils, vegetation)
and model simulated runoff volumes and deep
percolation to groundwater.
Septic system recharge. For domestic water
users that use individual septic systems, some
of the household-consumed water is eventually
recharged to groundwater. The presence of
septic systems within the Hydrologic Analysis
Area will be determined by comparison of the
location of residences and sewer infrastructure
(e.g., FS Update Figure 7) in consultation
with appropriate City staff; it is assumed that
septic systems are present where residences
are present and sewer pipes are absent. The
recharge rate for individual septic systems will
be assumed to be 147.5 gallons per day (gpd)
assuming 50 gpd per person based on a study
of septic system recharge within southern
California (Hantzche and Finnemore, 1992),
and an average population of 2.95 persons per
household in California (U.S. Census Bureau,
2018). Alternatively, water delivery records may
be used if available to estimate domestic water
usage per household.
Change in groundwater storage. As reported
in the FS Update, groundwater levels have
historically increased in this area due to increase
in the rate of groundwater recharge caused
by the disruption of drainage patterns and
the opening of fissures and cracks following

Dewatering wells discharge estimation. DBS&A
would visit and assess the location of the City
discharge line where extracted groundwater is
discharged to the beach and the Pacific Ocean
and measure total flow rates during two to four
time periods during the project. Discharge would
be estimated with the “Bucket and Stopwatch”
method, which entails measuring the time
discharge takes to fill a container of known
volume. Groundwater production from the
existing dewatering wells would be estimated
based on City records (if available) and discharge
data at the Pacific Ocean outfall.
Comprehensive groundwater balance. The
general groundwater balance equation for
the Hydrologic Analysis Area and Red Zone is
assumed as:
∆GWs = [Ip + Ii + S + GWi] - [E + GWo + R]
[Equation-1]
where ∆GWs is the change in groundwater
storage, Ip is deep percolation of precipitation
(including aerially distributed recharge and
focused recharge within the stream channels),
Ii is recharge from irrigation, S is septic system
recharge, GWi is groundwater inflow, E is
dewatering extraction, GWo is groundwater
outflow, and R is riparian evapotranspiration.
A comprehensive groundwater balance would
consist of quantifying all groundwater inputs
and outputs and comparing change-in-storage
from Equation 1 with groundwater change-in-
storage determined based on observed changes
in groundwater levels. Estimated change in
groundwater storage calculated with Equation
1 should be consistent with observed change-
in-storage based on groundwater level data.
Based on data availability, the comprehensive
groundwater balance would be conducted for a
recent representative period of at least 10 years,
and water-balance results would be reported on
an annual basis and as an average over the entire
period.
order to collect necessary groundwater elevation
data to support groundwater flow and recharge
estimation. Piezometers can be installed (and
later removed) with minimal impact to the
environment and locations would be identified
following field and inspection surveys listed
above. Upon installation, DBS&A would perform
limited aquifer testing (e.g., slug tests, step-
drawdown tests) to gather aquifer properties
data.
Rain gage installation. Three rain gauges would
be employed at the uppermost, middle, and
lowermost portions of the Hydrologic Analysis
Area to measure precipitation and characterize
precipitation variability with elevation (i.e., the
orographic effect). Standard cylindrical rain
gauges would be installed in areas determined
in consultation with the City and will be installed
on building roofs or on the ground surface with
minimal fencing around the gauge to prevent
damage. Approximately 0.01 inch of mineral oil
would be maintained in each gauge to prevent
evaporation. Gauge volumes will be checked
following wet weather events. DBS&A would
evaluate a correlation between data collected
from the installed gauges and regional (PRISM)
weather station data.
Riparian evapotranspiration. In areas of shallow
groundwater along stream channels riparian
vegetation access and transpire groundwater
at the water table via deep roots, and this
consumption could be included a water balance
of the area. The presence of and coverage area of
riparian vegetation would be determined based
on results of the streambed survey (Task C1)
and review of aerial photography. Groundwater
consumption by riparian evapotranspiration
can be substantial and would be estimated
based on the coverage area and assumed
evapotranspiration rates for southern-California
based on literature sources for the vegetation
types present.

DBS&A imported the map into our GIS. DBS&A will
utilize the GIS system to systematically identify
key existing fractures before a supplemental field
survey is planned and completed. The GIS work
and sitewalk will be completed to inventory the
fractures that need to be targeted for sealing. A
list of fractures will be prepared that itemizes each
fracture area and approximates the length, depth,
and width of the fracture that needs to be sealed.
A map will be produced showing each fracture and
the existing habitat at each location. Total fracture
volume can then be estimated in order to develop
an overall approach to the task and specify the
appropriate equipment and fracture sealant.
Several options will be evaluated for fracture
sealing that include a variety of equipment,
materials, and methods. Various sealing media
will be considered such as fill soil, bentonite clay,
or soil-cements. Sealant delivery options are
anticipated to include simple mixing and pumping
as well as mobile long-reach grout rigs. Each
option will be presented as a line item in a detailed
table that presents a technology summary,
advantages, disadvantages, effectiveness,
estimated longevity, costs, and other factors, such
as potential habitat impacts. The table of options
will be presented to the city and community for
discussion and evaluation that will ultimately lead
to selecting the best option.
D. Fracture Sealing (In-filling)
As noted in historical reports for the Portuguese
Bend area, stormwater has for years flowed out
of lower Portuguese, Ishibashi, and Paintbrush
Canyons and recharged directly into subsurface
groundwater in the landslide head scarp area
south of lower Burma Road. Groundwater recharge
in the head scarp area promotes slope instability
in the Portuguese Bend “Red Zone” area of greatest
displacement. Sealing this surface fracture area is
key to preventing future stormwater flow into the
head scarp and additional lubrication of the slide
plane failure surface.
This task consists of the following subtasks:
Field Survey
Evaluate Sealing Options
DBS&A has already conducted a preliminary field
survey of the fracture areas while visiting the
property on several dates in 2018. In addition,
DBS&A obtained a high-resolution topographic
map from the City that shows landslide area
topography with 1-foot elevation contours. This
topographic map shows several fractures in the
landslide head scarp area.
DBS&A imported the City topographic map to identify
existing surface fractures using GIS that will serve as the
basis for the Field Survey and development of a fracture
inventory in preparation for an Evaluation of Options for
sealing design.

proceeding beyond 30% design.
Meeting 2): A draft revised pre-construction design
incorporating City Council and City staff direction
will be presented to the City Council for further
review and approval.
Meeting 3): A final 100% construction-ready design
will be presented to the City Council.
DBS&A will prepare PowerPoint files for each
meeting for overhead presentation to the City
Council and public meeting attendees. Each
PowerPoint presentation will summarize the
completed work to date and illustrate the
proposed engineering options for review,
discussion, and approval. DBS&A will prepare and
distribute meeting minutes highlighting action
items.
F. Public Outreach Meetings
DBS&A staff were also pleased to attend several
community outreach meetings in 2018 during FS
Update preparation. DBS&A worked closely with
City staff to prepare for the community meetings
to present and describe the FS Update process
to stakeholders and to present the selected
engineering options developed through the FS
options analysis. DBS&A was able to develop a
collaborative working relationship with several
community members intimately involved in the
FS Update process and deeply interested in the
proposed remedies and the potential impact of
each option on existing habitat.
DBS&A has planned and budgeted for two
potential additional community outreach
meetings, if desired by the City. The meetings are
anticipated to be completed at important design
milestones. DBS&A will receive public comments,
including after the 30-day comment period, and
prepare a response-to-comments (RTC) document
to form the basis for continued discussion and
DBS&A will continue to build upon the collaborative
working relationship established with the City and
community stakeholders while presenting draft and
final design options.
E. City Council Meetings
DBS&A staff were pleased to attend several City
Council meetings in 2018 during FS Update
preparation. DBS&A presented summaries of
the historical work completed in the Portuguese
Bend landslide complex and the methods and
results of the prior FS reports that were completed
to evaluate options for landslide abatement.
Once our draft FS Update was nearly complete,
DBS&A rejoined the City council staff to address
public comments and incorporate public review
into the final FS Update. DBS&A answered many
questions during the meeting to help the city and
community move towards acceptable engineering
options for the FS Update.
Three additional public meetings are planned
as part of our proposed scope of work. DBS&A
understands that the City schedules regular public
meetings and DBS&A staff will plan to be available
on the scheduled dates. Our anticipated agenda
for each meeting is summarized below:
Meeting 1): A preliminary draft schematic design
for drainage and dewatering will be presented to

DBS&A received community comments during public
outreach meetings during the FS Update preparation
and incorporated the comments into a revised
conceptual surface water control design that will seek to
maximize habitat protection in the upper canyon areas.
G. Hydro-augers
As explained in and demonstrated in the FS
Update, given the project constraints, hydro-
augers (“hydraugers,” “horizontal drains,” or,
“directional drains”) are a means for mitigation of
the Portuguese Bend landslide complex with a
high chance of success. The design of an effective,
yet economical hydro-auger system requires an
in-depth understanding of the mechanism of
landsliding, engineering evaluations, value
engineering, and a means for monitoring of
mitigation progress, as explained below.
Hydro-augers are installed with specialty equipment
and contractors.
interaction with the community as final designs are
selected and approved. The City Council will review
and approve the RTC document. Two meetings are
anticipated for this proposal:
Meeting 1) Present and discuss draft proposed
plans and receive and /discuss community
feedback.
Meeting 2) Present and discuss final construction-
ready design and receive and discuss community
feedback.
DBS&A will prepare electronic presentations
using Powerpoint for each meeting for overhead
presentation. Each presentation will summarize
the completed work to-date and illustrate the
proposed draft and final engineering options
for review, discussion, and approval. DBS&A
will prepare and distribute meeting minutes
highlighting action items.
DBS&A worked closely with the City and community
stakeholders to collaboratively arrive at a consensus
regarding habitat preservation and engineering
solutions needed for landslide mitigation. Nearly 250
comments were received and addressed.

2. Reduce steady-state seepage (groundwater flow)
Both goals will be achieved by designing and
installing a system of hydro-augers. The first set of
hydro-augers will be advanced below the
postulated basal failure surface to relieve the
artesian pressure within the bottom portion of the
slide. These hydro-augers will not be significantly
affected (i.e., sheared-off, as would likely happen for
conventional vertical pumping wells drilled through
the base of the landslide) by the current relatively
large movement of the sliding mass (presently, on
the order of 8 ft/yr). Following the initial mitigation
stage to achieve artesian pressure relief and
reduced infiltration, additional hydro-augers will be
installed (with penetration into the sliding mass) to
lower the groundwater elevation, reduce steady-
state seepage forces, and improve the redundancy
and overall longer-term performance of the
dewatering system. To enhance drainage/relief of
artesian water pressure, a “casing perforating
device” may be used. This device is a perforating
gun to provide effective flow communication
between a cased wellbore and formation water.
The DBS&A team developed a three-dimensional
numerical model of the Portuguese Bend landslide
complex for the FS Update. Now built, it can be used to
cost-effectively evaluate various hydro-auger options.
Understanding of Mechanism of the
Landsliding
Slope failure at the Portuguese Bend
landslide complex is due to a combination
of hydrogeological and geotechnical factors,
particularly: (i) the presence of low-strength
materials along existing slide planes (basal
failure plane(s)); and (ii) the presence and flow of
groundwater. Although the proposed mitigation
strategy does not aim to address the first item
(i.e., mitigate low shear strength of materials), our
plan has a good chance of slowing the landslide by
addressing the second item (i.e., the presence of
groundwater).
The hydrogeologic (i.e., groundwater) conditions
within the Portuguese Bend area are complex.
They include not only steady-state seepage
(groundwater flow) within the sliding mass, but
also artesian pressure. There is strong evidence
that artesian pressure develops along the
stratigraphic contact of the Portuguese tuff
(geologic material characterized with very low
hydraulic conductivity), i.e. below the basal failure
surface that forms along this contact. There is
significant groundwater recharge that maintains
the steady-state conditions, and, likely, also
maintains the artesian pressure along the basal
failure surface. In our professional opinion, artesian
pressure is an important cause of landsliding, and
our proposed mitigation program is designed
accordingly.
Design of Hydro-Auger System – Conceptual
In addition to reduction of infiltration (e.g., see
Fracture Sealing Section D and Subsections C.I.4
and C.I.9, and the Subsections on Infiltration
reduction through channel lining and drainage
enhancement, C.I.4 and C.I.9), our approach to
achieving landslide mitigation encompasses the
following goals:
1. Reduce artesian pressures below the basal
failure surface
C-49

entered, best estimate of the piezometric surface,
and it only indirectly considered artesian pressure
4. Calibrate the model with updated piezometric
surface using output from the Hydrology Analysis
as available, steady-state seepage, and artesian
pressure to match the observed conditions
(i.e., Factor of Safety (FS) ≈ 1.0 (sliding); up to 8
feet per year of measured gross displacement) and
validate the results using a 2D analysis of a critical
cross section)
5. Evaluate the effect of “low infiltration” (e.g., using
the results of the Water Balance, calculate how
long will it take to increase FS to 1.25 and 1.5 and
hence mitigate displacements
6. Evaluate the following parameters of the hydro-
auger system: (i) location of hydro-augers;
(ii) number of hydro-augers; (iii) spatial orientation
of hydro-augers; (iv) length of hydro-augers; and
(v) diameter of hydro-augers. This evaluation will
be an iterative process that also includes cost
and time considerations. As discussed in the RFP,
concurrence by the City will be sought for each
“critical” step of this process
Upon completion of Step 6, the DBS&A team will
develop an implementation schedule
(i.e., Gant Chart), design drawings, and technical
specifications, and will develop a bid package.
Relevant calculations will be submitted
electronically (e.g., PDF) with the drawing and
specification package, as requested by the
City. The constructability and standard detail
requirements will be developed in consultation
with our proposed drilling subcontractor, Directed
Technologies Drilling (DTD).
DBS&A will also evaluate vertical groundwater
extraction wells in this task. Vertical extraction
wells are a traditional and effective groundwater
extraction technology where installed in
appropriate subsurface conditions. However,
vertical wells in the Portuguese Bend landslide
Design of Hydro-Auger System – Technical
Based on the DBS&A team’s extensive review
and cataloging of background information
during the FS Update, we find that the wealth
of existing investigation data will provide a
credible basis for an engineering evaluation and
preliminary design of the hydro-auger system.
Therefore, our preliminary design of the proposed
hydro-auger system will be based upon this
existing information. However, we may propose
supplemental subsurface investigation, if we find
that such information would fill needed data gaps
and benefit the project, (i.e., would reduce the
number and length of hydro-augers). This value-
added approach is further described in the “Value
Engineering/Monitoring Success” section of this
task.
The proposed hydro-auger system will be
designed based upon the results of engineering
evaluations, including 3-D seepage and slope
stability analyses. These engineering evaluations
will build upon the previous work by the DBS&A
team that was conducted as a component of the
FS Update, as follows:
1. Expand the 3-D slope stability model (depicted
in figure above) with SVSLOPE (https://soilvision.
com/product/svslope) of the site to include
additional areas affected by landsliding that
require mitigation or otherwise influence
landsliding, as necessary. The original 3-D slope
stability was built as a component of the FS Update
2. Refine and update the groundwater elevation
surface based upon the results of the Water
Balance Study described above
3. Apply steady-state seepage and artesian
pressure modeling options to more accurately
represent the observed phenomena using the
program SVFLUX which directly interacts with
SVSLOPE (https://soilvision.com/products/
svoffice-ge/svflux-ge). For the FS Update, the 3-D
slope stability model included only the manually-

As discussed in the FS Update, information on
file, for all three items listed above, is (or will be)
dated, and may not be accurate at the level that
would most benefit the project. Therefore, during
the implementation phase of this project, we may
propose to advance and instrument up to three
boreholes. The boreholes will be advanced within
the bottom third of the landslide mass and will
extend beyond the postulated basal failure surface.
They will be instrumented with:
(i) vibrating wire piezometer; and (ii) Time Domain
Reflectometers (tilt meters). Representative soil
samples for laboratory testing (saturated hydraulic
conductivity below and above failure plane) will
be recovered as well. The DBS&A team notes that
the proposed instrumented boreholes will be, in
part, sacrificial, as they will be intentionally allowed
to be damaged (i.e., sheared off) due to landslide
movement to help identify the failure surface and
record artesian pressures beneath it. However, the
benefits will likely outweigh the cost of additional
hydro-augers that might be required otherwise.
Cost-Benefit Analysis
DBS&A understands there are some stakeholders
in the community that have questioned the value
of significant geotechnical engineering work for
groundwater dewatering (and stormwater control)
compared to the relatively simple task of ongoing
periodic roadway repair along Palos Verdes Drive
South. The City has spent years and significant
budget continually assessing and repairing Palos
Verdes Drive South in an effort to maintain a safe
roadway into the community. Ongoing periodic
roadway repair will continue without a significant
increase in slope stability in this area.
DBS&A will complete a cost-benefit analysis
regarding hydro-auger design, installation
and maintenance compared to the ongoing
maintenance cost associated with maintaining
Palos Verdes Drive South. The cost/benefit analysis
will compare the routine costs and benefits of
complex haven proven to be problematic given
continual slope failure and land displacement. As
a result, as discussed in the FS Update, vertical
wells are anticipated to be more cost-effective
if installed later in the mitigation program once
some slope stability has been achieved with other
means, such as hydro-augers. A vertical wells plan,
if appropriate, will include design, placement, and
cost estimates.
Value Engineering/Monitoring the Success
As requested by the RFP and stated above, our
preliminary design of the proposed hydro-auger
system will be based upon existing information
provided by the City. It will be developed at a
level suitable for development of a bid package.
However, implementation of the hydro-auger
installation will be in phases as discussed in the
FS Update. This will allow for review of additional
information gathered during each phase of
installation, and potential adjustment of the
design (if it benefits the project). For example,
during the first phase of the implementation,
hydro-auger boreholes will be logged, sampled,
and tested, and flow out of the holes will be
recorded. This is valuable information that will
be processed, evaluated, and input into our 3-D
model of the site. The model will be re-run, and
the number and length of hydro-augers might be
adjusted accordingly.
Additional information that will benefit the project
includes:
Current (at the onset of the project/3-D
modeling) information on groundwater
elevation, flow direction, and artesian pressure
along the basal failure surface
Information on the basal shear surface (more
accurate elevation contours within the area
affected by landsliding)
Information on landslide movement (monument
survey)

periodic roadway assessment and repair with the
key issues related to the advantages and potential
disadvantages of hydro-augers including long-
term and short-term costs, slope stability, and
short-term and long-term benefits. The analysis
will consist of a series of order-of-magnitude
costing tables and a summary table summarizing
and scoring the pros and cons of each option.
Given the compromised nature of the current
roadway, the analysis would not be complete
without considering complete roadway collapse
and repair due to an episodic slope failure event.
DBS&A’s cost-benefit analysis will also consider this
scenario.
H. Utility Coordination
As part of this scope of work, DBS&A will contact
and coordinate with the appropriate public utilities
to ensure that utility lines and infrastructure are
fully identified and protected during upcoming
design planning for construction work. DBS&A
has already identified several utility line locations
during property area site walks and using the City
GIS layers.
Sewer lines, storm lines, and potable water lines
in the landslide complex are already input to the
GIS system that DBS&A prepared for the FS Update
and are ready for use during design document
preparation.
Existing sanitary sewer and potable water lines are maintained above-grade in the Portuguese bend landslide
complex due to ongoing slope failure.

Construction plans will be submitted to the
City in electronic (AutoCAD) format for review
and comment at the 30%, 60%, and 90% design
completion stages. At the 30% design stage,
DBS&A will also perform internal peer review of
the designs for constructability of the proposed
features. DBS&A will incorporate City comments
and deliver an electronic copy of the bid-ready
plan set at the 100% design stage.
J. Prepare Environmental Studies
The proposed drainage and dewatering design
project will be subject to the CEQA and will,
therefore, require the preparation of either
a Mitigated Negative Declaration (MND) or
Environmental Impact Report (EIR). DBS&A has
teamed with Envicom Corporation to assist with
this task. Envicom and DBS&A have successfully
collaborated previously for CEQA work related to
Pepperdine University in Malibu, California. Under
DBS&A direction and oversight, Envicom will
prepare an Environmental Assessment/Initial Study
to evaluate whether the potential project impacts
can be classified such that they require a MND or
whether a full EIR may be needed.
In order to determine the appropriate CEQA
document, Envicom will prepare an Initial Study
based upon the topics and questions included in
Appendix G to the CEQA Guidelines, also known
as the Environmental Checklist. Completion of the
Initial Study will determine whether the project
requires preparation of a MND or EIR. The Initial
Study will use information to be provided by the
I. Prepare construction plans
Based on the results of our engineering
evaluations, DBS&A proposes to prepare a set of
full-size construction plans (scaled 22 inches x
34 inches) for the proposed remedial measures.
Key features to be included in our construction
plan correspond to the expanded sheet titles, as
outlined below:
1. Title sheet, showing site vicinity map
2. Construction notes sheet
3. Existing conditions, including site topography,
existing utilities, and pertinent site features, such
as channel alignments, and fractures
4. Drainage plan showing limits of lined channel
installation and fracture infilling (i.e., fracture
locations and planned equipment layout)
5. Groundwater extraction plan, showing tentative
hydro-auger installation plan and section views
as well as locations of vertical extraction wells,
if any, included in the design; hydro-auger
installation plan will show entry and exit pit
locations, diameter, alignment, and confirmatory
geotechnical borings for the proposed drains;
Drains to be installed first (the first phase) will be
clearly labelled
6. Monitoring plan showing locations of
instrumentation for evaluating effectiveness of the
remedial measures; instrumentation will include
existing and proposed survey control points, TDRs,
and vibrating wire piezometers
7. Erosion control plan, showing locations
and types of temporary (i.e., in-place during
construction and, potentially, removed at the end
of construction) and permanent (i.e., to remain
post-construction) erosion control BMPs
8. Grading plan for provision of laydown areas,
equipment access, and working platforms for
installation of remedial measures

As we expect the Initial Study will find that most
issues are to be carried forward for analysis in the
Draft MND or EIR, a brief response to each of the
checklist questions will be provided. More detailed
responses will be provided where further analysis
in an MND or EIR is not warranted. Using this
approach, it is anticipated that the MND or EIR will
focus on the impact areas identified above and will
not require further analysis of the following:
Agricultural resources
Land use planning
Mineral resources
Population and housing
Public services
Since it is unknown which will be the appropriate
CEQA document after the Initial Study, a cost and
scope proposal for subsequent CEQA documents
will be provided after the Initial Study is complete.
K. Prepare Engineer’s Estimate
As a cost-saving measure, DBS&A will develop an
engineer’s estimate for the proposed remedial
work during preparation of the 60% design
construction plans, including construction
quantities and construction quality assurance
program costs. This will be an order-of-magnitude
cost estimate for planning purposes and will be
developed based on a combination of DBS&A
in-house cost data for recent similar construction
projects, publicly available data (e.g., Caltrans,
FHWA), and discussions with the DBS&A team
subcontractors. An additional contingency line
item will be included assuming 10% of the total
estimated costs. The estimated quantities and
costs will be updated as needed to reflect design
modifications at the remaining plan submittal
stages (i.e., 90%, and 100%).
City or developed during the project’s design
phase. This includes available project-specific
technical studies, and descriptive materials as well
as information available in the public domain. For
each topical area included in Appendix G to the
CEQA Guidelines, Envicom will provide existing
conditions information; the applicable regulatory
framework (relevant laws, ordinances, regulations
and standards); list of thresholds of significance;
and if possible, based upon available data, provide
analysis of direct and indirect impacts. Each
evaluation will provide supporting documentation
and reasoning to justify the CEQA conclusions,
including citations to project technical studies and
other data sources. Where sufficient information
is not available to determine project impacts,
the Initial Study will serve to focus the scope of
the CEQA document by identifying issues where
additional technical study is necessary to evaluate
the full impacts of the project. To that end, we
intend to utilize the Initial Study to focus the scope
of the CEQA document and potentially needed
technical studies to evaluate those impacts that
are potentially significant. Based upon a review of
the available project materials and conversations
with City staff it is anticipated that the following
will be the key environmental issues for the
project:
Aesthetics/visual resources
Air quality/greenhouse gas emissions
Biological resources
Geology
Hydrology/drainage/water quality
Construction related Noise
Hazards and hazardous materials
Utilities
Transportation
Recreation
Cultural resources/tribal cultural resources

P. Estimated Construction Project
Schedule
DBS&A will prepare an itemized overall project
construction schedule as part of the overall
deliverables. The schedule will be built in MS
Project and converted to a suitable format for the
City if needed such as pdf. The draft schedule will
be reviewed by City staff and comment will be
incorporated into the draft before a final schedule
is prepared.
Q. Project Surveying
DBS&A has teamed with McGee Surveying
Consulting for this task. After incorporating earlier
surveys that started in 1994, McGee Surveying
has completed the City’s annual GPS surveys of
the landslide complex monuments since 2007
to document land movement on an annual basis
in the Portuguese Bend area. The annual McGee
Surveying reports form the basis for quantification
of overall land displacement and definition of the
“Red Zone” area of greatest land movement in the
landslide complex. DBS&A and McGee Surveying
will ensure that any future work is conducted
consistent with the methodology of the past work,
consistent with the California Professional Land
Surveyor’s Act, while protecting and maintaining
the established survey monuments in the area.
All reports as appropriate will be submitted to Los
Angeles County to be recorded. Relevant surveying
details will be incorporated into draft and final
drainage and dewatering design plans as needed.
R. Project Updates
DBS&A will work with City staff throughout the
project to prepare and submit documents, images,
and maps, meeting notes, progress reporting,
communications, event timelines, etc., suitable for
upload to the City website for public review. The
documents will be compatible with City software
and will be based on our extensive library of
historical imagery, data, and information as well
as updated information regarding the status and
schedule of the dewatering and drainage design
project tasks. Website updates can be generated at
any time upon City request. However, DBS&A will
prepare the website updates on at least a monthly
basis for the duration of the project including
submittals after public meetings and outreach
events.

Selected Relevant Projects
Portuguese Bend Landslide Mitigation Feasibility Study, City of Rancho
Palos Verdes, Los Angeles County, California
Principal-in-Charge leading a geologic and engineering team to develop an
updated feasibility study (FS) that will be used to identify a solution to
stabilize the Portuguese Bend Landslide Complex (PBLC). There has been
extensive damage to City assets from PBLC movement, resulting in over $45
million in City maintenance costs, permanent damage to private property,
and significant and ongoing risks to human health and safety. The FS solution
is comprised of 1) capture, control, and conveyance of regional storm water
to prevent infiltration into the PBLC; 2) groundwater extraction from the
PBLC using horizontal drains; 3) control of infiltration septic wastewater; and,
4)stabilization of city utility infrastructure in the PBLC vicinity. A significant
engineering challenge to the project is that wells or structures constructed as
part of the solution are at near-term risk of destruction by the continuing
PBLC movement. Findings of the FS will also be used to leverage federal
infrastructure funding for project implementation. Dr. Cullen presented the
FS findings to a diverse group of stakeholders including the City Infrastructure
Management Advisory Committee, City Public Works Dept. Staff, City Mgt.
Staff, the public, the Palos Verdes Peninsula Land Conservancy, and the City
Council. He answered numerous questions, and lead discussions on a PBLC
landslide mitigation path forward acceptable to all stakeholders.

Olcese #2 Well Remediation and Repair, City of Bakersfield, California
Principal-in-Charge for evaluation of a defective agricultural well (Olcese well #2) and recommendations as to
the well’s potential for rehabilitation or whether it should be replaced. Review of a downhole video and the
original driller’s report revealed several major issues contributing to the wells poor performance, including:
casing and screen mineral encrustation, damage to the casing resulting from land subsidence, and debris and
more than 30 feet of sediment in the bottom of the well. Rehabilitation measures were recommended and
subsequently implemented to clean and repair the well. Well rehab was accomplished at a small fraction of the
cost of well replacement.
San Antonio Creek Spreading Grounds, Ventura County Watershed Protection District, Ventura, California
Principal Hydrogeologist responsible for the assessment of hydrology, geology, and the designed diversion
works; intake pipelines; and water conveyance for the project as consultant to Ventura County Watershed
Protection District. DBS&A completed a 100-percent design for diverting a portion of the precipitation that is
typically lost downstream to rehabilitate spreading grounds and aquifer recharge wells. Project resulted in
greater groundwater storage and production from local water supply wells and less reliance on already limited
surface water supplies. Installed depth-discrete monitoring well near the spreading grounds to monitor the
effectiveness project and help to develop a better hydrogeologic understanding of the Ojai Valley Groundwater
Basin. Numerically modeled future groundwater elevation trends.
Stormwater Detention-Groundwater Recharge Project Development, Sonoma County Water Agency, Sonoma
County, California

requirements. Of unique interest is the role that the ubiquitous Monterey formation plays in contributing to the
naturally high background levels of selenium originating from native geologic sources.
Development of a Hydrologic Characterization and Groundwater-Surface Water Budget for Newport Bay
Watershed, Orange County Public Works Department, California
Principal Hydrogeologist and technical reviewer responsible for oversight for a water budget being developed to
support mitigation of high concentrations of nitrogen and selenium in the shallow groundwater in the historic
Swamp of Frogs area. Groundwater discharges are a major contributor to chemical impacts in the Newport Bay
watershed. Interacted with and presented findings to multiple municipal and private stakeholders.
Hydrologic Analysis, Kern River Environmental Impact Report, City of Bakersfield, California
Principal Hydrogeologist and technical reviewer responsible for oversight of the quantitative evaluation of
groundwater impacts that will result from planned increased Kern River flows through the City of Bakersfield.
The 118-year historical record of upstream and stream-reach Kern River flow was used as the basis for the initial
design and development of a water resource database and to conduct water balance modeling in order to
project stream channel losses due to evapotranspiration and infiltration, and to evaluate how far downstream
flows of various planned magnitudes will reach. Subsequently, a comprehensive groundwater database was
designed and developed incorporating historical groundwater elevation and water quality data from hundreds
of wells. Data was acquired from the City and numerous adjacent water purveyors. Using the constructed
databases, a telescoped, customized version of the U.S. Geological Survey Central Valley numerical groundwater
flow model was used to quantify long-term aquifer overdraft, impacts of river losses to groundwater levels,
gradients, flow to municipal well fields, and the impacts of alternative groundwater pumping scenarios. A plan is
currently being developed to augment the database with data from additional wells, piezometers, and recharge
facilities. The database will be used for ongoing monitoring of aquifer conditions, efficacy of recharge, and the
impacts of groundwater extraction.
Re-Design, Installation, and Testing Oversight of Vadose Zone Monitoring System, PG&E, Hinkley, California
Principal Hydrogeologist responsible for technical review of engineering specifications and drawing for vadose
zone monitoring system retrofit consisting of pore-liquid samplers at PG&E’s Hinkley Compressor Station.
Determined that originally designed system was fatally flawed and provided system redesign. The redesigned
system also had to address the challenge of a retrofit lysimeter installation in a 22° jack-and-bore slant borehole.
Dr. Cullen provided the design details and procurement specifications. He also directed DBS&A’s oversight of
construction and initial testing of vadose zone monitoring program, including installation activities for four

Residential Development, Bramalea of California, Diamond Bar, Los Angeles County, California
Project Manager - Michael managed the geotechnical tasks associated with a large, proposed residential hillside
development. Typical tasks associated with a landslide-prone, soft bedrock geologic environment (Puente
Formational and others) were performed. Characterization, analysis, and mitigation of a large pre-existing
landfill resulting from progressive failure were completed.
Residential Development, Carma-Sandling Development, Laguna Niguel, Orange County, California
Project Manager - Michael managed a comprehensive geotechnical/geologic study for a hillside, residential
development. Geologic environment included several large landslides, compressible alluvial soils and expansive
soils. Slope stability analyses were performed for temporary and permanent slopes. Extensive analysis of
existing landslide stability and remedial measures was performed. The project also included deep canyon fills
(+100 feet) and field instrumentation of existing landslides.
Residential Development, Olympia-Roberts, Chino Hills, Riverside County, California
Project Engineer - Michael served as project engineer for a large proposed residential development. The project
included a study of a large, ancient landslide that would be potentially destabilized by the proposed grading. A
detailed observational construction sequence was developed, which resulted in not reactivating the landslide.
Review of Applicant’s Geotechnical and Seismic Characterization and Analysis, Cortina Landfill, USEPA, Region
9, Colusa County, California
Senior Technical Advisor - Mr. Yacyshyn was retained by USEPA to review the geologic characterization, slope
stability analysis, and mitigation recommendations for a proposed new landfill on tribal lands. Two rounds of
review and response to applicant comments were completed. The proposals landfill site had numerous small
landslides and other geologic hazards. My Yacyshyn reviewed the applicant‘s field investigation program and the
results of the characterization. The proposed grading for the landfill would remove many of the small landslides,
but several more substantial slides would remain and would possibly be undermined by the proposed grading.
Mitigation schemes were identified and communicated to the applicant.
Static and seismic slope stability analysis results were also reviewed. Questionable selection of non-hazardous
solid waste properties rendered the static stability analysis results to be unreliable. Recommendations for
alternative non-hazardous solid waste properties were provided to the applicant.

Stabilized Earth (MSE) walls, debris removal, and slope reinforcing with riprap.
Dr. Matasovic is a co-author of the Federal Highway Administration (FHWA)
guidance document on geotechnical earthquake engineering for highway
facilities and is a recipient of the 2001 Prakash Foundation award for
excellence in geotechnical engineering.
Key Project Experience
Portuguese Bend Landslide Complex, City of Rancho Palos Verdes, California
Dr. Matasovic served as a Lead Geotechnical Engineer for development of an
engineering feasibility study for remediation of the subject landslide, including
restoration of the affected community infrastructure. Over one mile of critical
coastal roadway and sewer, power, and potable water lines have been
significantly compromised for decades along Palos Verdes Drive South in
western Los Angeles County since significant landslide activity was reactivated
in 1956. Dr. Matasovic’s hands-on involvement included preliminary three-
dimensional (3D) stability evaluation of the main landslide complex and
development of the preferred landslide remedial solution (horizontal drains)
that is minimally invasive to the habitat and residences nearby.
La Pata Avenue Gap Closure, San Juan Capistrano, California. Dr. Matasovic
served as Engineer of Record for the Geotechnical investigation and evaluation
is support of the proposed extension of the La Pata Avenue (Central Segment;
Geotechnical scope of work budget: $1,000,000+). The proposed extension will
traverse a Holocene landslide deposit that is approximately 0.6 miles long and
up to 300 feet thick. The landslide deposit is within the Capistrano formation,
a formation widely regarded as southern California’s most unstable geologic
formation. Scope of services called for an execution of a focused site
investigation program that included geologic mapping, geophysical
measurements (surface refraction and in-hole geophysics), drilling, trenching,
sampling, and geotechnical laboratory testing of representative landslide
deposit material. The work further included interpretation of site groundwater
conditions, development of basal shear plane geometry, and 2D and 3D static
and seismic slope stability evaluations. Project challenges included
demonstration that an ancient landslide deposit (FS = 1.0) will be suitable
subgrade for the proposed road extension.

Tarapaca Landslide, City of Rancho Palos Verdes, California – Investigation and Remediation. Dr. Matasovic
served a lead Geotechnical Engineer for the evaluation of the causes, risks (to residences and adjacent road),
and for development of potential remedial solutions for stabilization of an active landslide. The landslide has
been moving into the San Ramon Canyon that is adjacent to Palos Verdes Drive East. At the closure of the
project, Dr. Matasovic assisted City of Rancho Palos Verdes in development of cost-effective solution for the
landslide mitigation, including with management of sediment within the San Ramon Canyon.
Ocean Trails Country Club Landslide - Forensic Investigation and Landslide Remediation. Prior to a new golf
course opening on the Palos Verdes Peninsula, a landslide that was incorporated into the 18th fairway and green
moved approximately 50 ft ocean-ward destroying the 18th hole. This caused water lines, drain lines and a
sewer line to be severed. County Sanitation Districts of Los Angeles County (LACSD) retained Geosyntec (Dr.
Matasovic’s former employer) to evaluate causes of landsliding and options for relocating their sewer line so
that it would not be damaged by future landsliding within this property. Dr. Matasovic was responsible for
stability evaluations, including development of representative landslide geometry and material parameters.
Work included review and interpretation of logs of hundreds of past exploratory boreholes to construct
structure contour maps of the subsurface geology and to construct geologic cross sections through the site. The
cross sections were used to prepare geotechnical stability sections for use in stability analyses at various stations
along the sewer alignment. Results of the stability analyses provided information about the risk of potential
future damage to the existing sewer due to instability and for options relocating the sewer to avoid future
instability issues.
Frank R. Bowerman Landfill Phase V-B/C Landfill Expansion, Orange County, California. During construction of
the Frank R. Bowerman (FRB) Landfill Phase V-B/C landfill expansion project, a landslide occurred within the
upper 100 feet of the slope. Although Dr. Matasovic’s employer was the CQA consultant (not the designer) on
the project, OC Waste & Recycling requested that it provides geological and geotechnical services for
remediation of the landslide on an emergency basis so that construction could continue and repairs could be
incorporated into the contractor’s construction schedule. Dr. Matasovic was involved in planning and execution
of the geotechnical investigation and testing programs, including recovery of representative basal shear plane
samples for testing in a torsional ring shear device. Dr. Matasovic further directed detailed stability evaluations
of the failed slope to support preparation of three alternative design options for remediation of the landslide
and for stabilizing an adjacent 700 linear feet of the slope where similar geologic conditions were present. The
stabilization was performed with up to 600-ft long horizontal drains spaced 50 to 100 ft apart.
San Diego Gas and Electric Transmission Towers Access Road Stability Demonstration, San Diego, California.
San Diego Gas and Electric (SDG&E) owns and maintains transmission towers within the Sycamore Landfill and
Hanson’s Gravel Pit mining operation in San Diego, California. In order to allow for a lateral expansion of the
landfill, several transmission towers had to be relocated. Relocation of these towers called for design and
construction of an access road, and permitting with multiple agencies. Given the site constraints, section of the
access road was graded at 1H: 1V (Horizontal: Vertical) and the slope was approximately 190 feet high. Dr.
Matasovic served as Project Manager and was responsible for permitting. Project challenges included
development of three-dimensional (3D) slope model for stability evaluations and back-analysis of nearly vertical
slope to evaluate model input (shear strength) parameters.
La Pata Avenue Road Distress, San Juan Capistrano, California. Geotechnical Engineer of Record for
investigation of a cause of the La Pata Avenue road distress. The distress was caused by re-activation of an
ancient landslide which was initiated by grading for a residential development at the toe of the slope. Work

The project consisted of design of a new landfill within an area affected by landsliding. Design challenges
included temporary stabilization of 60-acre active landslide including slot cut design for construction of remedial
measures. Dr. Matasovic served as Project Director. He also acted as a Lead Geotechnical Engineer responsible
for directing the static and seismic stability evaluations in support of the buttress design, for numerical slope
stability analyses with FLAC V7.0. These analyses included evaluation of allowable displacements during
construction (i.e., (slot cut), and for a back-analysis of the basal shear plane material parameters. The back-
analyses were calibrated based upon actual slope movements recorded in 20 inclinometers. Dr. Matasovic was
also responsible for performing seismic hazard evaluation, development of design ground motions, and for
seismic deformation analyses.
Sunshine Canyon Road, Mechanically Stabilized Earth Wall Retaining System for Slope Stabilization, Sylmar,
California. Dr. Matasovic was the design engineer for a Mechanically Stabilized Earth (MSE) retaining wall
system. This MSE retaining wall system was designed and constructed adjacent to Sunshine Canyon Landfill
within the City of Los Angeles (City) right of way and was subject to approval and inspection by the City of Los
Angeles Department of Public Works. This was one of the first such walls approved by the City of Los Angeles.
The design was based upon stability evaluations with MSEW. The CQA services included in-situ nuclear density
testing of reinforced backfill soil, monitoring of installation of precast concrete elements and reinforcing
materials, and monitoring of construction of back of wall gutter and drain system. Dr. Matasovic reviewed and
sealed the CQA report for this project.

Fairview Park Geotechnical Investigation and Slope Stability Analysis, Costa Mesa, California. The 211-acre
Fairview Park extends along the southwest edge of the City of Costa Mesa, California, just east of the Santa Ana
River and County of Orange Talbert Nature Preserve (Talbert Nature Preserve). The project was
multidisciplinary. Relevant project requirements called for extension of the existing wetland (extends along the
sections of the Santa Ana River) into the Talbert Nature Preserve to establish significant native habitats,
including California native grasslands, coastal bluff scrub, open sandy coastal scrub, and riparian wetlands.
However, as this extension would, in turn, submerge the toe of the west-facing slope of an existing bluff, known
as the “Overlook Slope,” concerns about slope stability were voiced out. The Overlook Slope is approximately
2,000 ft (0.38 miles) long and up to 70 ft high while slope face inclination ranges from 1.0H: 1.0V (Horizontal:
Vertical) to 2.0H: 1.0V. Dr. Matasovic was Geotechnical Engineer of Record and Geotechnical task manager for
this project. He was responsible for seismic hazard assessment, planning and execution of geotechnical
investigation, planning and execution of geotechnical laboratory testing program, and for static and seismic
slope stability evaluation. Project challenges included sampling of bluff material (cemented gravels) and
subsequent interpretation of geotechnical testing results.
Lopez Canyon Road, Lake View Terrace, California. Dr. Matasovic was responsible for geotechnical services at
Lopez Canyon Road over a three-year period. The work included supervision of in-grading geologic mapping,
post-earthquake investigation of a landslide behind an on-site office complex, design of a drilled pier/soldier pile
retaining wall for stabilization of an active landslide area, and foundation design for a liquid storage facility. Dr.
Matasovic also helped install and monitor two groundwater observation wells, worked with the lead geologist to
identify active fault traces within an Alquist-Priolo special studies zone, and assessed the suitability of local and
imported borrow soils for soil buttress construction at the project site.
Calabasas Landfill – North Ridge Cut Expansion, Agoura, California. Project Manager and Lead Engineer
responsible for execution of this $1,600,000+ geotechnical investigation and analysis project. The work included
coordination of several drilling, CPT sounding, and geophysical logging contractors, installation of an
inclinometer in landslide deposit, aquifer testing, groundwater sampling, soil and rock sampling, interpretation
of field and laboratory testing results, engineering analyses and evaluations, and management and coordination
of 24 professionals involved in the project. Dr. Matasovic is also responsible for a engineering report that will
document results of engineering analyses, including static and seismic slope stability evaluation (of cut, man-
made and waste slopes and inclinometer readings), seismic site response analyses (landslide deposits and waste
fill), steady-state seepage analyses (to design and optimize landfill underdrain system), static and seismic
settlement analyses, and soil liquefaction analyses.
Puente Hills Site – Phase 1B and Eastern Canyons Expansions, Whittier, California. Task Manager responsible
for static and pseudostatic slope stability and deformation analyses conducted in support of design and
construction of Phase 1B Expansion. The analyses were conducted to evaluate several subgrade configurations
considered and included evaluation of landslide remedial measures. The work also included cost-benefit
analysis for remedial measure considered and was concluded with detailed design of selected stabilization
alternative (rock anchors). For the Eastern Canyons Dr. Matasovic provided geotechnical support during
development of the conceptual grading design. He was also involved in planning of geotechnical investigations
and geotechnical laboratory testing, and was responsible for execution of a supplemental field investigation
program which included drilling of a borehole with a large-diameter bucket auger, downhole logging of the
borehole, and excavation of several trenches in local Puente formation.

Badlands Disposal Site – Canyon 4 Phase 2, Riverside County, California. Project Manager responsible for
overall coordination of landslide mitigation project. Dr. Matasovic also served as a Lead Engineer responsible for
geotechnical aspects of the project, including drilling, sampling, geotechnical laboratory testing, back analysis of
an existing landslide, static and seismic analysis of very steep native cut slopes in the immediate vicinity of the
slide, development of landslide remediation design, and static, pseudostatic, seismic site response and seismic
deformation analyses for interim and final configurations of remediated landslide. Along the course of this
project, Dr. Matasovic demonstrated that landsliding was in an isolated area of unfavorable bedding and
hydrogeological conditions, and that native slopes outside of that area can be safely cut at 1H: 1V (Horizontal:
Vertical). Later resulted in 188,000 cubic yards of additional air space (i.e., waste disposal volume).
Chiquita Canyon Landfill, Valencia, California. Task Manager for stability evaluations conducted in support of
developing construction drawings and specifications for the Area C, Cell II, Phase 2B expansion. For Canyons A,
C, and D, Dr. Matasovic was responsible for stability analyses conducted to support the revised landfill cover
design and final cover grading plans. Along the course of Geosyntec/University of California, Berkeley NSF-
sponsored research projects on the performance of solid waste landfills in the 17 January 1994 Northridge
earthquake Dr. Matasovic was involved in back analyses of Canyon A and Canyon D response to the earthquake.
The back analyses involved pseudostatic slope stability, two-dimensional seismic site response and Newmark-
type seismic deformation analysis.
Heaps Peak Sanitary Landfill, San Bernardino County, California. Project Manager and Lead Engineer
responsible for directing static and seismic slope stability evaluation of this “mountain” side hill-fill landfill in the
San Bernardino County. Project challenges included landfill base as steep as 2.4H: 1V (Horizontal: Vertical),
perennial steady state seepage parallel to the landfill base, and relatively high seismicity of the site (design
bedrock PHGA = 0.4 g). Dr. Matasovic evaluated shear strength parameters at the landfill base by back-
analyzing observed landfill behavior in the 1992 Big Bear earthquake and subsequently demonstrated that the
landfill can sustain design seismic loads provided that the liquid levels are maintained below certain elevation.
The stability evaluation was based upon the results of three-dimensional (3-D) pseudostatic slope stability
evaluation, 2-D seismic site response and steady-state seepage analyses, and 1-D Newmark-type seismic
deformation analysis. In 1999, Dr. Matasovic led the post Mw 7.1 Hector Mine earthquake reconnaissance team
at the site.
Lamb Canyon Sanitary Landfill, Riverside County, California (2 Consecutive Projects). Project Manager
responsible for seismic site response and deformation analyses for the Phase 2 Stage 2 (P2S2) expansion of the
Lamb Canyon Sanitary Landfill. Project challenges included demonstration of static stability of proposed cut
slopes with out-of-slope bedding and demonstration of seismic stability of a composite landfill liner system
subjected to bedrock Peak Horizontal Ground Acceleration (PHGA) of 0.6 g. The seismic stability demonstration
was based upon the results of site-specific interface testing of encapsulated GCL and a non-linear seismic site
response analysis. Average acceleration time histories from the non-linear seismic site response analysis were
processed in a Newmark-type seismic deformation analysis to demonstrate that calculated permanent seismic
displacements are lower than 6-in. stability criterion established by California DWR and adopted by the Santa
Ana RWQCB. Subsequent project included evaluation of seeps and wet spots in the P2S2 expansion area,
development of the underdrain system design, and evaluation of the underdrain system effect on the interim
waste fill stability.

mitigation projects, landfill design and earthworks projects, has designed
numerous earth-retaining structures (including Mechanically Stabilized Earth,
MSE walls), deep and shallow foundations, embankment fills, and was
involved with application of geosynthetics in variety of geotechnical and
geoenvironmental projects.
Key Project Experience
Landslide Stability Evaluation – La Pata Avenue Gap Closure, San Juan
Capistrano, California. Mr. Witthoeft served as project engineer for the
geotechnical investigation and evaluation in support of the proposed
extension of the La Pata Avenue (Central Segment; Geotechnical scope of
work budget: $1,000,000+). The proposed extension will traverse a Holocene
landslide deposit that is approximately 0.6 miles long and up to 300 feet thick.
The landslide deposit is within the Capistrano formation, a formation widely
regarded as southern California’s most unstable geologic formation. Scope of
services called for an execution of a focused site investigation program that
included geologic mapping, geophysical measurements (surface refraction and
in-hole geophysics), drilling, trenching, sampling, and geotechnical laboratory
testing of representative landslide deposit material. The work further included
interpretation of site groundwater conditions, development of basal shear
plane geometry, and 2D and 3D static and seismic slope stability evaluations.
Project challenges included demonstration that an ancient landslide deposit
(FS = 1.0) will be suitable subgrade for the proposed road extension.
Landslide Stability Evaluation – Storm Water Capture, Puente Hills Material
Recovery Facility, Whittier, California. Mr. Witthoeft served as project
engineer for the geotechnical investigation and evaluation in support of a
proposed storm water diversion basin at the Puente Hills Material Recovery
Facility (PHMRF) in Whittier, California. Based on the project team’s field
geologic mapping, a potential landslide was identified in the ascending slope
south of the proposed basin. Mr. Witthoeft performed back-analysis of the
potential landslide to estimate shear strength of the basal shear surface and
performed static and pseudostatic slope stability analyses to evaluate the
translational and rotational stability of the slope. The results of the hillside
stability evaluations indicated that calculated factors of safety for the
proposed condition are relatively low and could be approaching unity. The
results further indicated that the construction of the proposed storm water

basin does not adversely affect the stability of the approximately 125-ft high ascending slope. A qualitative
evaluation of the impact of an approximately 300-ft high slope was performed as well. It was concluded that
landsliding within that slope is outside of zone of possible impacts on the proposed improvement.
Cut Slope Stability Evaluation – Cell CC-4 Back-Cut and Buttress Slope Stability Evaluation, Sunshine Canyon
Landfill, Los Angeles County, California. Mr. Witthoeft served as project engineer for the stability evaluation of
proposed back-cut and buttress fill grading plans for the Cell CC-4 expansion at Sunshine Canyon Landfill (SCL) in
Los Angeles County, California. The portion of the SCL considered in this evaluation is generally underlain by
sedimentary rocks of the Towsley Formation. The Towsley Formation in this area generally consists of an upper
claystone stratum overlying a sandstone stratum. Slope stability of the Towsley Formation materials is
significantly influenced by the strength and orientation of the bedding planes. Moist conditions observed in the
bedrock, as well as piezometer measurements, suggested the presence of relatively shallow groundwater. Mr.
Witthoeft performed back-analysis of observed landslides at the site to estimate shear strength of the Towsley
Formation claystone and performed forward stability analyses to develop recommended geometry for back-
cutting and buttress fill placement to provide a stable interim condition for composite liner construction and
placement of new waste fill.
Slope Stability Evaluation and Seepage Analysis – Broad Beach Biofiltration Project, Malibu, California. Acted
as the staff engineer for geotechnical evaluation of site suitability for various infiltration features along Broad
Beach Road in Malibu, California. Oversaw geotechnical exploration activities, including hollow-stem auger
drilling, Geoprobe, infiltration test well installation and abandonment, and in-situ infiltration testing. Back-
calculated hydraulic conductivity of subsurface soils and estimated effect of stormwater infiltration on
groundwater elevations using SEEP/W finite element analysis software and considering the results of the field
investigation. Developed representative cross sections along the alignment, evaluated shear strength
parameters from in-situ and laboratory test results, and performed slope stability analyses.
Seepage Analysis – Sheet Pile Wall Evaluation and Design Alternatives, Dana Point and San Juan Capistrano,
California. Acted as the project manager for a third-party peer review and development of economical design
alternatives for a 2,100 ft-long sheet pile wall. Developed the proposal, including scope-of-work, cost, and
schedule. Reviewed previous consultants’ geotechnical reports to develop representative design parameters.
Performed engineering calculations using DeepXcav, SLOPE/W, and SEEP/W software packages, evaluated the
client’s proposed open-cell design concept, and drafted report conveying relevant findings. Reduced sheet pile
design length from previous consultant’s recommended value by over 40%, generating significant savings for the
client.
Geosynthetics Construction Quality Control – Tajiguas Landfill, Santa Barbara, California. As staff engineer, Mr.
Witthoeft performed on-site construction quality control (CQC) during placement of engineered fill and
subdrainage within an existing channel and during placement of composite liner system geosynthetics (GCL and
HDPE geomembrane). Reviewed various contractor submittals for conformance with specifications.
Geosynthetics Design and Construction Quality Control – Marine Corps Air Ground Combat Center Landfill No.
2 Southern Expansion, Twentynine Palms, California. As staff engineer, Mr. Witthoeft performed various design
calculations for veneer stability of the operations / LCRS soil layer as well as for wind uplift and thermal
expansion/contraction loading of the composite liner system. Performed CQC for placement of concrete in
drainage channels and for placement of geosynthetic composite liner system (GCL and HDPE geomembrane).

Asset Management Plan for Water Supply Wells, California Water Service Company, California
Cal Water operates over 800 water supply wells throughout California, and the California Public Utilities
Commission requires Cal Water to submit a General Rate Case application every three years to demonstrate that
their water rates accurately reflect the cost of providing service. The Asset Management Plan identifies and
characterizes aging infrastructure in Cal Water’s districts, such that deteriorating wells can be identified and
prioritized for replacement (new well installation) or rehabilitation (well liner installation). Consistent with
industry standards (such as American Water Works Association standards), Ms. Erbele provided an assessment
of the condition, criticality, and long-term reliability of wells within the Cal Water Districts.
Litigation Support for Contaminated Groundwater Site, Carson, California
Ms. Erbele developed an electronic master site plan for the Site area in the industry-standard GIS. The GIS site

location for critical review and evaluation. In addition, environmental data such as groundwater elevation
contours, groundwater flow direction data, and environmental sampling data for soil vapor, soil, and
groundwater was added over the infrastructure imagery to develop concise maps and presentation slides for the
Site area and adjacent properties. Groundwater flow and groundwater contaminant maps for all included
properties combined were developed to provide a regional understanding of contaminant sources, fate, and
transport. Development of a master site plan for the Site area and adjacent properties allowed for a unified
understanding of environmental conditions regarding the sources, fate, and transport, of identified soil, soil
vapor, and groundwater contaminants in the Site area.

REPRESENTATIVE PROJECT EXPERIENCE
Paradise Valley Specific Plan EIR, Riverside County (Coachella Valley)
Mr. Cullen is the principal in charge for the Program Environmental Impact Report (EIR) addressing a self-
sustaining new town proposed in the Shavers Valley portion of Eastern Coachella Valley, in unincorporated
Riverside County, along the I-10 freeway, just south of Joshua Tree National Park. The Specific Plan would guide
development of approximately 8,500 residential units, 1.38 million square feet (sf) of commercial development and
associated public facilities and infrastructure, including parks, trails, schools, and fire and sheriff facilities on a
2,000-acre development footprint within a 5,000-acre property ownership. The subject property will require the
dedication of thousands of acres of land in open space conservation in compliance with Coachella Valley MSHCP.
Self-sustaining features of the new town include a mix of land-uses to reduce external commuting, use of solar
energy, and provision of electric car chargers in residential garages and at specified commercial locations. Key
issues for the project are biological resources, traffic, noise, views from the freeway and nearby parks and other
public places, air quality and greenhouse gas emissions. A Climate Action Plan (CAP) has been prepared for the
project, tiering off Riverside County’s CAP.
2000 Avenue of the Stars Environmental Impact Report, City of Los Angeles
Mr. Cullen co-managed the preparation of an EIR for the 2000 Avenue of the Stars Project. The project proposed to
revitalize the old ABC Entertainment Center by removing two existing structures and constructing a single mid-rise
office building and three-acre landscaped plaza. Key responsibilities included maintaining excellent communication
with the local residential community and assuring comprehensive analysis of potential environmental effects. Key
issues included hazardous materials removals, traffic, aesthetics, and geotechnical concerns.
Marina del Rey Oceana Retirement Facility and Holiday Harbor Courts EIR, County of Los Angeles
Mr. Cullen managed preparation of the Marina del Rey Oceana Retirement Facility and Holiday Harbor Courts EIR.
The project included the 114-unit Oceana Retirement Facility for Parcel OT of the Marina del Rey Local Coastal
Program (LCP) area, as well as the Holiday Harbor Courts commercial development for the 2.55-acre Parcel 21,
which would replace existing uses with new commercial uses, a public park plaza and promenade, and parking. Key
issues of analysis included land use and planning, water quality, and traffic.
Malibu Institute Environmental Impact Report, County of Los Angeles
Mr. Cullen was the principal in charge and contributed to preparation of an EIR for the Malibu Institute Project,
which proposed to develop a sports-oriented educational retreat in the unincorporated Los Angeles County on
the 650-acre site of an existing golf course. The project would replace existing structures used for dining and
A-51 C-115
golf course operations, with a combined 224,287 sf of structures for educational and meeting facilities,
overnight accommodations, dining facilities, fitness center/spa, golf course clubhouse, and associated
maintenance and support facilities. In addition, the project would remodel the existing 18-hole golf course. The
project design incorporated many “green” features to minimize environmental impacts. The site was located in
the Coastal Zone of the Santa Monica Mountains and issues evaluated in the EIR included aesthetics impacts on
vistas, scenic highways, visual character, and lighting, biology, air quality, historic and archaeological cultural
resources, hydrology, noise, fire protection and wildland fire hazards, traffic, and utilities.
Village at Los Carneros Project EIR, City of Goleta
Mr. Cullen managed preparation of an EIR for the Village at Los Carneros Mixed Used Residential Project. This
project included 465 residential units on a 45-acre project site. The project included a mix of residential uses
including both alley loaded and front loaded single-family detached homes, town homes in triplex, four-plex, and
six-plex configurations, condominium flats arranged around central courtyards with semi-subterranean parking and
two apartment complexes, including workforce housing. A public bicycle trail and a 5-acre passive public park were
incorporated into the project and private recreational facilities, including two swimming pools, a clubhouse, and
pocket parks were provided for future residents. The project site was located immediately adjacent to the U.S. 101
freeway and the Union Pacific Railroad (UPRR) railroad tracks, which carries both freight and passenger trains. A
freeway overpass and south-bound off-ramp are located just beyond the project’s northeast corner. In addition, a
perennial creek and associated riparian corridor traverse the west boundary of the project site. The creek is a
designated Environmentally Sensitive Habitat Area (ESHA) and the General Plan requires a 25-100-foot upland
steam protection area and its treatment was challenged by a coalition of environmental groups. A portion of a
Chumash village occupied the southwest corner of the site. Entitlements included the repeal of the original Specific
Plan, Zone Change, Development Plan Amendments, a Conditional Use Permit, approval of a Development
Agreement, and approval of a Vesting Tentative Tract Map. The project’s EIR addressed the full range of
environmental issues including air quality with an emphasis on proximity to transportation uses, noise associated
with both railroad and vehicular operations, greenhouse gas (GHG) emissions, vibration issues associated with
railroad operations, hazards and hazardous materials, also associated with railroad operations and truck traffic,
general traffic, land use and aesthetics, including impacts to view corridors that address the Santa Ynez Mountains
and ridgelines. The project’s EIR was certified in June 2014.
Conrad N. Hilton Foundation LEED Platinum Headquarters Campus
Mr. Cullen provided project management for site planning, entitlement and CEQA compliance for the Conrad N.
Hilton Foundation headquarters campus in the City of Agoura Hills. The project included the creation of a
contemporary-style office campus, which provided the growing Foundation a central headquarters to operate,
maintain, and coordinate its long-term charitable projects. The project incorporates design elements to maximize
energy efficiency, create an inviting work space, and achieve a LEED Platinum Certification. Envicom kicked off
the project with preparation of technical studies and an Environmental Constraints Analysis (ECA) to inform the
project design team of the constraints and opportunities associated with development of the site. The ECA was
utilized by the team to create a project layout that showcases the site is natural resources and is “light-on-the-land”.
Throughout an extensive design process, Envicom Corporation prepared a proponents Administrative Draft EIR for
the project, and continued to work with the design team to provide feedback regarding significant impacts. This
process allowed the design team to refine the project prior to submittal of the application and reduce or avoid
impacts, which would have required costly mitigation and potentially hindered project approval. This internal
feedback loop is an example of Envicom’s interactive approach to environmental consulting illustrating our
extensive experience and comprehensive understanding of the CEQA and entitlement processes. Subsequent to
receipt of the project approvals, Envicom Corporation worked closely with the Hilton Foundation and the City of
Agoura Hills to implement, monitor, and document compliance with the project Conditions of Approval and
Mitigation Monitoring Program. Envicom's involvement included compliance on environmental mitigation
measures, and other general conditions of approval required prior to issuance of the Grading Permit and Permit.
A-52 C-116

Project Experience
DBS&A completed the Feasibility
Study (FS) Update for the Portuguese
Bend Landslide Complex in 2018. Due
to widespread landslide activity for
decades, a segment of Palos Verdes
Drive South in the City of Rancho
Palos Verdes, nearly half a mile long,
has been continually deformed
from lateral stress driving south
with slope failure at the toe of the
Portuguese Bend landslide complex.
Despite nearly $45 million expended
by the City, slope failure, disrupted
stormwater drainage, and accelerated
groundwater recharge contribute to
an ongoing, costly, and challenging
cycle of roadway and utility damage
and repair. Despite significant City efforts, uncontrolled stormwater from the upper
slopes of the Portuguese Canyon Watershed has flowed directly into the most
geotechnically sensitive and unstable areas within the interior of the Portuguese
Bend landslide area. Stormwater recharge to groundwater increases subsurface
artesian pressure and promotes landsliding across a broad area unsuitable for
buildings, roads, or utilities.
DBS&A worked closely with City staff and the community to develop conceptual
solutions to control regional stormwater, extract groundwater, preserve habitat, and
help stabilize and secure land movement in the Portuguese Bend area.
DBS&A prepared the FS Update based on historical work completed to evaluate
traditional engineering options. DBS&A proposed an innovative and cost-saving
flexible liner solution for stormwater control that allows for habitat reconstruction
after build-out. Stormwater control would prevent continual hydraulic loading to
key areas in the subsurface to significantly reduce regional slope failure and mass
landsliding. Supplemental groundwater extraction that has proven effective in
controlling slope failure in adjacent areas such as Abalone Cove was also considered
along with sub-horizontal groundwater drains (hydraugers or hydro-augers)
and surface fracture sealing (in-filling) to further prevent stormwater recharge to
groundwater.

A three-dimensional (3-D) numerical geotechnical model was constructed to simulate various remedial
engineering solutions, and demonstrate and quantify the effectiveness of dewatering. The proposed solutions will
be carefully integrated into habitat restoration and maintenance areas outlined in the Portuguese Bend Natural
Communities Conservation Plan/Habitat Conservation Plan (NCCP/HCP).
DBS&A attended several City council meetings and community meetings and conducted a community workshop
to present the draft conceptual FS plans and receive and discuss public comments. After addressing nearly
250 comments, DBS&A revised the draft conceptual FS plans to incorporate public comments and concerns to
achieve a collaborative consensus to move the program forward into the design and construction stage.

Landslide Mitigation at the Sunshine Canyon Landfill (SCL), Los Angeles, CA
GLA performed investigations and analyses to assess the causes of
surficial cracking and suspected down-slope movement in future
development areas of this active landfill on the northern margin of the
San Fernando Valley in Los Angeles, California. This canyon landfill site
is marked by steep ridges and steep-sided ravines shaped by the
underlying sandstone and claystone geology. Artesian groundwater
pressures are locally present. GLA concluded that instability was due to
the amphitheatre-shaped geologic structure presenting out-of-slope
bedrock bedding planes from multiple directions, as well as elevated
groundwater pore pressures due to confinement by overlying claystone
strata.
GLA’s extensive geotechnical investigation has involved geologic
mapping; rock core and soil borings; downhole acoustic televiewer
geophysics; downhole logging of large-diameter hollow-stem auger
borings; test pit logging; on-going monitoring of a network of
piezometers and inclinometers; installation and operation of pumping
wells and 1,400-ft long horizontal drains for dewatering and relief of
artesian water pressure; laboratory testing of soil and groundwater
samples; geologic, hydrogeologic, and geotechnical interpretation;
stereographic rock mass discontinuity analyses; seismic hazard
evaluations; two-dimensional (2D) and three-dimensional (3D) slope
stability analyses; 2D steady-state seepage analyses, seismic
deformation analyses; and development of landslide mitigation
recommendations (1,400-ft long horizontal drains).
GLA is currently monitoring the progress of the dewatering/landslide
mitigation with a system of inclinometers and vibrating wire
piezometers.

Nelson Road Landslide Repair
geo-logic.com Page 1
Emergency Geotechnical Services for Landslide
In March 2011, a landslide originating east of the Nelson Road right-of-
way buried the roadway. The buried roadway blocked access to about 27
homes. The Geo-Logic Associates' (GLA) project team was authorized
on short notice to provide emergency consultation to the County of Santa
Cruz Public Works (CSCPW) and County Counsel, and was authorized to
investigate the landslide. The investigation was to characterize the
landslide sufficiently to permit decisions regarding options moving
forward.
Geologic reconnaissance and mapping of the site and general
vicinity; subsurface investigation by means of HQ rock coring and large-
diameter borings drilled to assess landslide hazards; installation
of slope inclinometer casings paired with vibrating wire piezometers
to monitor slope stability and groundwater conditions; installation of
stakes across scarp features to facilitate detection of ongoing
deformation; acquisition and processing of LiDAR flown specifically for
this project, and processing of data to generate a “bare earth”
digital elevation model (DEM); assessment and re-processing of
2010 (pre-landslide) LiDAR data, and comparison of the pre- and post-
landslide LiDAR data sets; geologic and engineering analysis of our
data, including two dimensional slope stability analyses; development
of conclusions regarding the mechanics and apparent controls on
landslide movement; research into possible mitigation options, in
particular the geologic/geotechnical feasibility of clearing the existing
Nelson Road alignment.
The results of geologic and geotechnical evaluations were used to
develop options for mitigation of the landslide. The mitigation options
were reviewed and evaluated by CSCPW prior to development of the final
mitigation option. Access to the affected homes was restored soon
thereafter, and the final remedy was implemented by late 2011.

Project Experience
DBS&A worked with City of
Newport Beach Public Works to
characterize hydrology in the
upper Big Canyon Watershed.
Big Canyon was deeply incised
by stream erosion into marine
terrace formations near the
northern terminus of the San
Joaquin Hills. Erosion exposed
Tertiary aged marine deposits
in the area including the
marine Monterey formation.
The Monterey formation
has been recognized as the
naturally occurring source of
selenium released to the aquatic
environment in several California
watersheds, including Big Canyon. The Big Canyon area was largely undeveloped
until the 1970s when a water supply reservoir and adjacent residential tracts were
constructed.
DBS&A completed a hydrogeologic characterization and water balance to help the
City further understand the relationship between selenium detected in the area,
the underlying Monterey siltstone, shallow groundwater, and residential irrigation.
Over-irrigation activities from residential areas were suspected of contributing to
groundwater mounding in the shallow aquifer and subsequent selenium flux from
the underlying Monterey formation. DBS&A constructed a detailed water balance
with a focus on the upper Watershed in the vicinity of the reservoir and adjacent
neighborhoods to characterize the potential impact of suspected over-irrigation and
reservoir design discharge on shallow groundwater mounding and selenium flux in
the Watershed.
DBS&A installed a set of seven piezometers to supplement the existing piezometer
network near the reservoir. Stable isotopes of oxygen and hydrogen (delo/delD)
were utilized to evaluate groundwater recharge from various sources. DBS&A
also installed a surface water staff gauge to compare surface water elevation to
groundwater elevation in nearby streams. DBS&A collected continuous flow rate
data from storm water lines in the area to assess surface water discharge related to
irrigation rate and frequency. DBS&A also conducted soil, groundwater, and surface
water sampling and analysis to evaluate selenium impacts. A greater understanding
of the sources, occurrence, and mechanisms of selenium flux enabled the City to
ultimately design remedial measures for selenium impacts in the Watershed.

SDG&E Transmission Towers Access Road
geo-logic.com Page 1
Access Road Stability
Demonstration
San Diego Gas and Electric (SDG&E) owns and maintains transmission
towers within the Sycamore Landfill and Hanson’s Gravel Pit mining
operation in San Diego, California. In order to allow for a lateral
expansion of the landfill, several transmission towers had to be
relocated. Relocation of these towers called for design and construction
of an access road, and design permitting with three agencies. Given the
site constraints, section of the access road between towers 2 and 3 was
just next to a temporary cut slopes that was graded at 1H: 1V
(Horizontal: Vertical). The slope was approximately 130 ft high between
benches and approximately 190 feet high between its toe and crest.
To assess the stability of such a high and steep slope GLA developed a
conventional two-dimensional (2D) slope stability model and a three-
dimensional (3D) model that could encompass a relatively complex
geology, as mapped by GLA geologists. The 3D stability model
developed is shown in the figure above. The material parameters for
stability evaluations were evaluated by back-analysis of nearly vertical
slopes nearby that were graded by landfill operations in the same
formation. For quality control purposes, and to satisfy the request of the
regulatory agency, the back-calculated material parameters were
compared to the results of geotechnical laboratory testing on remolded
samples by GLA and other consultants.
Per SDG&E requirements, the analysis was performed under static and
seismic loading conditions. The 3D analysis was required to demonstrate
static and seismic stability. The results of the 2D analysis (approximately
30 percent lower) were presented for quality control purposes. GLA also
developed requirements for slope observation during construction and for
in-grading monitoring.

Project Experience
DBS&A assisted OC Watersheds in the development of a comprehensive water
balance for central Orange County in an area known as the former “Swamp of the
Frogs.” The former wetlands was a depositional environment receiving regional
stream flow and surface water runoff for centuries until rapid urbanization starting
around 1925 led to significant hydrologic and hydrogeologic changes. The wetlands
was partially drained when surrounding land was developed for agricultural use.
Later, with increased area development, the wetlands area was fully drained and
surface water flow was largely captured by a network of interconnected surface
water and flood control channels extending across central Orange County. The
network of surface water channels lowered the groundwater table while capturing
stormwater flow. The channels are now located below the regional groundwater
table and receive groundwater in-flow throughout much of the former wetlands
area.
DBS&A assisted the County with an evaluation of water sources and sinks in the
vicinity of high selenium detections within the channel network. DBS&A conducted
a hydrogeologic characterization, estimated recharge and infiltration, mapped
groundwater flux and flow, assessed selenium flux, and developed a quantitative
water balance. The
County’s goal was to
better understand
and ultimately control
selenium flux so it can be
reduced or eliminated
to meet U.S. EPA’s Total
Maximum Daily Load
(TMDL) requirements.
DBS&A also proposed
innovative solutions for
selenium treatment in
groundwater, including
engineered treatment
wetlands.
DBS&A also worked with
community stakeholders
to present the methods
and results of the study.

La Pata Avenue Gap Closure
geo-logic.com Page 1
Road Extension Feasibility Study, Design, and Permitting
The proposed extension of the La Pata Avenue will traverse a Holocene
landslide deposit that is approximately 0.6 miles long and up to 300 feet
thick. The landslide deposit is within the Capistrano formation, widely
regarded as southern California’s most unstable geologic formation. The
groundwater is approximately 150 ft above the landslide deposit basal
shear plane. The site is in an area of high seismicity, with design
Moment Magnitude of 7.2 and site bedrock Peak Horizontal Ground
Acceleration (PHGA) of 0.47 g. Environmental concerns such as limits of
an endangered species habitat preclude re-alignment of the road and/or
construction of a stability buttress at the toe of landslide deposit.
Scope of services called for an execution of a focused site investigation
program that included geologic mapping, geophysical measurements
(surface refraction and in-hole geophysics), drilling, trenching, sampling
and geotechnical laboratory testing of representative landslide deposit
material. The work further included interpretation of site groundwater
conditions, basal shear plane geometry, and results of torsional ring
shear testing of basal shear plane materials.
Based on the results of this investigation, the team developed two- and
three-dimensional (2-D and 3-D) stability models to demonstrate static
and seismic stability of the proposed improvements. Project challenges
included assessing present-state Factor of Safety (FS) of landslide
deposit that was required for back-calculation of basal shear plane shear
strength parameters, development of representative 2-D cross sections,
reconciliation of back-calculated shear strength parameters with
strengths from laboratory torsional ring shear testing, and establishment
of static and seismic stability criteria that are suitable, yet achievable for
the proposed improvement.
The team was able to demonstrate that, upon grading for proposed
improvements, static and seismic stability criteria established for this site
will be met without construction of a costly berm at the toe of Landslide
Deposit C.

Project Experience
DBS&A worked closely with Directional
Technologies Drilling, Inc. (DTD) for
a unique horizontal well installation
project in New Mexico. The Santa Fe
County Judicial Complex (SFCJC) site is
a New Mexico Environment Department
(NMED) site in historic downtown
Santa Fe, New Mexico with complex,
co-mingled groundwater contamination.
NMED selected DBS&A through a
competitive bid process to complete a
grout barrier around the property and to
install horizontal wells for groundwater
extraction.
The purpose of the grout barrier was
to impede groundwater flow during
construction of underground parking
and to partially mitigate impacts from
construction dewatering activities. Due
to an existing shoring system at the
site, the majority of the barrier installed
required high-pressure jet-grouted columns to form the barrier. The grout barrier
layout consisted of 600 linear feet of jet-grouted elements that overlapped with the
ends of a 185-foot-long slurry wall. The barrier was 22 feet high, with 4 feet above
and 18 feet below the static water table. Overlapping elements were installed in an
alternating pattern with additional grouting near existing shoring piles.
Due to site limitations, the only feasible method to access targeted groundwater
was to install horizontal wells underneath existing structures. DBS&A designed and
oversaw the completion of three horizontal wells with approximately 180 feet of
screen and a total length between 280 and 320 feet. Drilling initiated through the
side of a 20-foot-deep excavation, proceeded horizontally underneath existing
buildings, and daylighted in an adjacent parking area. DBS&A made connections
to tie the horizontal wells in to both the north and south sides of the project
area, which allowed extraction from both ends of the site. This project was the
first application of horizontal vapor extraction wells by the NMED. This project
has significantly reduced the risk of impacts to surrounding properties and the
environment.

Geotechnical Engineering Services for Design of Phase D
GLA provided geological and geotechnical design services to
assess the geological, hydrogeological, seismic and soil/bedrock
mechanical conditions at the Prima Deshecha Landfill in Orange
County, California. Work was conducted within and in the vicinity
of the Phase D development area to evaluate soil conditions that
affect the stability of a proposed excavation along with the
interim and final refuse fill slopes proposed for landfill
development.
To evaluate the site conditions affecting slope stability, field,
laboratory, and research studies were conducted to collect
relevant geotechnical data for the Phase D area. These studies
indicated that a portion of the Phase D development area is
underlain by landslide deposits which include Landslide “A”, while
the northern portion of the development area may also be
underlain by Landslide “D”. Landslide “D” had not been
investigated previously. Understanding the local geometries of
these two landslides, the structural geology of the underlying
Capistrano Formation, and local hydrogeologic conditions was
necessary to design excavation and refuse fill grades that will have
acceptable factors of safety under static and earthquake loading
conditions to meet the applicable state and federal regulatory
requirements. This dictated special provisions to deal with deep-
drilling and coring performed to evaluate the presence of weak
beds at depth that could affect stability.

Slope Stabilization
geo-logic.com Page 1
Geotechnical Engineering Services for Slope Stabilization
Geo-Logic Associates, Inc. (GLA) provided technical services in support
of the pre-design of the Los Alamos County Landfill in New Mexico.
These services included geological mapping, geotechnical investigation,
design, and pre-bid, and bid support services provided to Los Alamitos
County., Project challenges included performing evaluations in support of
repair of the existing landfill cover and during investigation, pre-design,
design and repair monitoring of a relatively large area affected by slope
instability that affected the function and safety of the landfill perimeter
road. The slope instability was caused by a rapid accumulation of storm
water from an event that greatly exceeded the 100-year storm.
The field work included geological mapping and trenching. The trenches
were excavated by backhoe in environmentally-sensitive areas along the
landfill perimeter. Several representative samples of the subgrade
material and from a local borrow source were recovered for testing. The
testing included both index testing and direct shear testing for evaluation
of representative strength parameters.
Engineering evaluations included slope stability evaluation and design of
a 20-foot high Mechanically Stabilized Earth (MSE) wall. The design
work included preparation of design report, drawings, preparation of
technical specifications, bid documents, and included bid support.

To meet requirements of the National
Pollution Discharge Elimination
System (NPDES) individual permit
issued by the United States
Environmental Protection Agency, Los
Alamos National Laboratory is required
to manage storm water discharges
from legacy Solid Waste Management
Units at a storm water drainage
catchment area.
The objective of this project is to
divert storm water runoff from Los
Alamos town-site around the drainage
in which the historic outfall discharged
wastewater from former Laboratory
operations. The proposed pipeline
will discharge the run-on water from
the town-site into Los Alamos Canyon
immediately upstream of two existing
storm water retention ponds. This will increase the existing ponds’ ability to retain
storm water generated from the historic outfall and drainage.
One particular challenge is the lack of access from the town-site area and limited
access (no heavy equipment) within the side drainage. DBS&A is working closely
with the installation contractor to develop a design that achieves both long-term
performance and addresses constructability constraints.
Designing the conveyance line also faced challenges due to extremely steep
slopes; unstable and fractured rocks in the drainage limiting anchorage points;
rocks with sharp edges that may gauge the pipeline during thermal expansion and
contraction if not properly managed; and limits on anchorage locations due to soil
contamination. DBS&A’s design team worked with engineers from pipe suppliers
to pipe support manufacturers to produce a design that will work within these
constraints.
The design of the diversion pipeline considers impacts to historic and cultural
resources and sensitive species. Where the pipeline crosses an historic trail, a
footbridge will allow continued trail access. Located in core habitat for the Mexican
Spotted Owl, noise and equipment restrictions are in place during the pipeline
construction window. Planning for the design phase takes these constraints into
account to ensure to comply with natural and cultural restrictions on-site.

Under-performing, the existing
stormwater system at Rio Rancho
Landfill results in flooded roads and
sediment deposition problems during
rain events. DBS&A was contracted by
Waste Management of New Mexico
to evaluate the previous design and
provide recommendations to address
problems with the existing system.
The goals of this effort were to:
Better manage stormwater
conveyance to keep existing
roadways operational during and
after rainfall events
Minimize maintenance activities
associated with stormwater/
sediment deposition
Optimize the use of existing ponds
Minimize large erosion events that
compromise roads, ponds, and drainage facilities
All existing components of the stormwater system were identified and assessed
for sufficient capacity to meet current needs and compliance with regulatory
requirements. Assessment of existing infrastructure covered both design and
construction practices. Through this assessment, DBS&A identified deficiencies in
the existing system and provided a design for strategic system changes to meet the
goals stated above without a complete overhaul of the entire system. As this is an
active landfill, constructability of stormwater improvements during landfill operation
was an important consideration in the revised design. DBS&A completed permit-
level calculations and drawings to update the landfill’s closure plan, subsequently
submitted to NMED.
DBS&A is completing construction level plans and specifications to implement
the recommended improvements. These documents cover re-grading existing
stormwater ponds, installation of new culverts, and installation of improved
emergency spillways on stormwater ponds.
