BEACH CLUB, AND SEAVIEW NEIGHBORHOODS BASED ON SUDDEN
ENERGY SHORTAGES, PLANNED DEENERGIZING EVENTS, AND INTERNET
SERVICE SHUT OFFS AS ESTABLISHED BY RESOLUTION NOS. 2024-52 AND
2024-57 FOR AN ADDITIONAL 60 DAYS.
FISCAL IMPACT:
Approving a professional services agreement with GLA for final engineering design and
related services for the Portuguese Bend Landslide Remediation Project (CIP 8304) will
result in fiscal impact of up to $529,787 inclusive of contingency. The approved Fiscal
Year (FY) 2025-26 CIP includes funding for final engineering design, environmental
documents, and related services for this project; of which $700,000 is from the CIP Fund
as the required 30% matching funds for the Federal Emergency Management Agency
(FEMA) Building Resilient Infrastructure and Communities (BRIC) grant that the City was
awarded for Phase 1 Design in the amount of $2.3 million as the 70% federal funds. Staff
notes that FEMA previously issued a notification that the BRIC program was being
discontinued; however, recent court filings indicate that the program is not being
discontinued. FEMA representatives have verbally informed the City that the City’s Phase
1 Design award will continue, and Staff are seeking written confirmation. Should the BRIC
program not provide funding for this work, the City funding in the approved FY 2025 -26
CIP is sufficient to complete the study.
Approving submittal of an application to the FEMA Hazard Mitigation Grant Program for
the Portuguese Bend Landslide Remediation Project requires a $10 million local match.
Based on the projected FY 2025-26 fund balance and assuming all CIP projects are
completed, the Capital Infrastructure Program (CIP) Fund is estimated to end the year
with a $2.2 million balance, with an additional $5 million held in reserves. As a result,
sufficient funding is not available from the CIP Fund to meet the match requirement.
The City Council may consider allocating the required match from the City’s General Fund
unallocated balance. According to projections presented at the FY 2025 -26 budget
workshop, the General Fund is expected to end the year with a $27.3 million balance, o f
which $17 million is held in reserves and $10.3 million unallocated. For cash flow
purposes, staff anticipates that the $10.3 million will be needed to support the FEMA
Voluntary Property Acquisition Buyout Program, with reimbursement expected within the
same fiscal year. Therefore, should the City Council elect to allocate the $10 million match
from the General Fund for the Portuguese Bend Landslide Remediation Project , the
timing is anticipated to be reasonable, as the project is expected to be a multi-year project.
Once the FEMA grant has been awarded, a budget appropriation request for the matching
funds of $10 million will be presented to the City Council for consideration. VR
Portuguese Bend Landslide Budget
The Portuguese Bend Landslide emergency response is projected to reach approximately
$48 million from the period beginning in October 2022 through the fiscal year (FY) ending
June 30, 2025, including purchase order carryovers and continuing appropriations from
FY 2023-24. This amount is funded through various sources, including the General Fund,
CIP Fund, ARPA, Supervisor Hahn’s Social Program Grant, and Metro Funds.

As part of the FY 2025-26 budget process, the City Council directed staff to present a
priority list of landslide emergency response projects/activities totaling $9 million so that
the City Council may consider future budget reductions based on the priority order rank
list. As such, included in this report is the ranked priority order list of projects. Should the
City Council enact any budget reductions, then any agreements/contracts for those
projects/activities impacted by the budget reductions could be cancelled or reduced with
30 days due notice to the vendor and payment for costs incurred within the cancellation
period, if applicable.
Since the majority of expenditures occurred in FY 2024-25, the following summarizes the
approved appropriations and expenditures for that fiscal year:
For FY 2024-25, the City Council appropriated $36.8 million (including Purchase Order
carryovers and continuing appropriation from FY 2023 -24) for emergency work outside
the normal bidding process due to the emergency declaration as follows:
• $23.9 million for emergency response, boreholes and deep dewatering wells
(DDW), including $9.6 million approved on May 7, 2024 (unspent balance from
Hydraugers Project by June 30, 2024 was carried over in FY 2024-25) and $6.1
million on October 1, 2024.
• $4 million for emergency stabilization measures for additional DDWs approved on
October 1, 2024.
• $4 million for winterization approved on October 1, 2024.

o Appropriating the remaining $110,000 from the CIP Fund.
• $500,000 from the CIP Fund for additional operations and maintenance costs
associated with the DDW Program approved on May 6, 2025.
Assistance to the geologic hazard abatement districts was approved in the form of loans
and in-kind assistance as follows:
• On February 4, 2025, the City Council affirmed the use of the financial assistance
loan to Abalone Cove Landslide Hazard Abatement District (ACLAD) in the amount
4
of $1.6 million approved by the City Council on July 2, 2024 for ACLAD to
implement their deep dewatering well plan; and

BACKGROUND:
The Greater Portuguese Bend Landslide Complex, sometimes called the Ancient Altamira
Landslide Complex (Landslide Complex) encompassed four historically active landslide
areas in the City: the Portuguese Bend Landslide (PBL), the Abalone Cove Landslide
(ACL), the Klondike Canyon Landslide (KCL), and the Beach Club Landslide (BCL). The
Landslide Complex now also includes areas outside of the City’s historical boundaries of
those known landslides, predominantly uphill from the PBL and ACL, within the Landslide
Complex as mapped by various agencies (i.e., U.S. Geological Survey and California
Geological Survey) and other researchers.

On October 3, 2023, the City Council conducted a discussion regarding the conditions of
the Landslide Complex. After considering information presented that evening, including
public testimony, the City Council unanimously adopted Resolution No. 2023-47 declaring
the existence of a local emergency within the geographic boundaries of the Landslide
Complex and adopted Urgency Ordinance No. 674U to establish a 45-day moratorium on
the acceptance or processing of applications, issuance of permits, and construction of all
structures within the Landslide Complex (Moratorium). The City Council has extended the
local emergency on multiple occasions, and it remains in effect until August 30, 2025,
unless extended again this evening.
On August 20, 2024, the City Council authorized the emergency installation of immediate
stabilization and protection measures consisting of deep dewatering wells (DDWs) in
response to exponential acceleration of the Landslide Complex as a result of historic
rainfall during the 2022-23 and 2023-24 rainy seasons.
On October 1, 2024, the City Council authorized an expansion of the DDW program to
the Abalone Cove area, on City-owned property. Additionally, the City Council authorized
a winterization program on City-owned property in the Landslide Complex without waiving
the Abalone Cove Landslide Hazard Abatement District’s (ACLAD) and Klondike Canyon
Landslide Hazard Abatement District’s (KCLAD) responsibilities as identified in their plans
of control.
On February 18, 2025, the City Council affirmed only using the $1.6 million City loan to
implement ACLAD’s DDW Plan including two monitoring wells and instrumentation that
would be installed, maintained and operated by ACLAD within their jurisdictional
boundaries. A sum of $100,000 was also approved to provide ACLAD with professional
services (i.e. project management and geologist).
On March 18, 2025, the City Council approved amending the loan agreement to ACLAD
by extending the first loan payment from December 1, 2025 to December 1, 2026; and
updating the scope to include the implementation of DDWs.
Tonight, the City Council will receive its 60-day standing report on the current conditions
of the Landslide Complex and consider extending the prohibition of one- and two-wheeled
vehicles along Palos Verdes Drive South through the Landslide Complex and extending
the Local State of Emergency and Building Moratorium.
DISCUSSION:
Current Conditions
Geologic Conditions
The City’s contracted geologist, Mike Phipps of the firm Cotton, Shires & Associates, Inc.
(CSA) previously reported that rainfall from the wetter than average rainy seasons in
2022-23 and 2023-24 and the resulting runoff and infiltration into the Landslide Complex
had an adverse effect on the landslide area.
The 2024-25 rainy season has been drier than average and has been relatively beneficial.
As of August 12, 2025, only 6.58 inches of rain has fallen at the Rolling Hills Fire Station
7
56 rain gauge since the start of the 2024-25 rainy season (October 1, 2024), representing
just 48% of the season average. The impact of the well below-average 2024-25 rainy
season continues to be beneficial in terms of landslide movement, which generally
continues to slowly decelerate in areas that are still moving. This is believed to be largely
due to significantly below-average rainfall through early-August, positive effects from the
major winterization efforts undertaken by the City and ACLAD and KCLAD in the fall and
early winter, and ongoing dewatering efforts by the City and ACLAD and KCLAD.
Recent GPS survey data published by McGee Surveying Consulting for the approximately
“monthly” monitoring periods ending July 1, 2025 and August 5, 2025 were reviewed and
analyzed (Attachment E).
Figures 1 and 2 present scaled displacement rates (i.e., movement velocities), movement
vectors, and contours (aka “heat map”) of displacement rates for the July 1, 2025 and
August 5, 2025 full monitoring periods. (Attachment D)
Figure 1: Scaled Displacement Rates for July 1, 2025 Monitoring Period

Figure 2: Scaled Displacement Rates for August 5, 2025 Monitoring Period
For all points monitored across the entire Landslide Complex, the following are the key
conclusions for the time period of June 3 through August 5, 2025:
• The ACL movement, within its historical boundary, has decelerated an average of
approximately 25% between June 3 and August 5, 2025. The average rate of
movement for these points was 0.99 ft/month from June 3 through August 5, 2025.
The ACL movement has decelerated an average of 69% since the deep
dewatering program commenced mid-September 2024. The fastest moving area
remains the upper portion of the ACL at an average of 1.15 feet per month (about
3.2 inches per week); however, the area of the ACL moving in the 3 to 4 inch per
week range (light blue area on the heat map Figures 1 and 2 above) continues to
shrink considerably, most likely in response to recent deep dewatering efforts by
ACLAD. It is anticipated that this movement rate will continue to decelerate as
dewatering production increases.
• The PBL, within its historical boundary, has decelerated an average of 24% from
June 3 through August 5, 2025. The average rate of movement for these points
was 0.58 ft/month from June 3 through August 5, 2025. The PBL movement has
decelerated an average of 83% since the deep dewatering program commenced
in mid-September 2024. Following completion of DDWs 1 through 6, by late
October 2024 the PBL experienced a dramatic reduction in movement velocity.
From October 2024 through mid-February 2025 the PBL was viewed as having
reached a steady state of movement. A slight uptick in movement velocity
occurred in response to rainfall in February and March 2025; however, since April
9
2025, the GPS monitoring data indicate that the PBL has been steadily
decelerating.
• The KCL continues to have no measurable movement since mid -October 2024.
Although some points in the KCL appear to show measurable changes in their
GPS position, these movements are at or below the limits of instrument precision.
Further absolute vector analysis shows that the changes are not in a consistent
progressive pattern, but rather in random directions, which indicates GPS “noise”
rather than actual movement. This lack of measurable movement indicated by the
GPS survey in the KCL continues to be corroborated by periodic field
reconnaissance of the Seaview and Portuguese Bend Beach Club (PBBC)
neighborhoods performed by CSA. Because there is no movement occurring, the
KCL has decelerated 100% since the deep dewatering program commenced in
mid-September 2024.
• The Greater Ancient Altamira Landslide Complex/Ancient Portuguese Bend
Landslide Complex points outside of the historical boundaries of the ACL and PBL
have decelerated an average of 25% from June 3 through August 5, 2025. The
average rate of movement for these points was 0.90 ft/month from June 3 through
August 5, 2025. The Greater Portuguese Bend/Ancient Altamira Landslide
Complex points have decelerated an average of 72% since the deep dewatering
program commenced in mid-September, 2024.
• There continues to be no measurable movement of points along the Burma Road
switchbacks since December 3, 2024. Vector analysis performed on the GPS
points in this area confirms that the reported data represent GPS instrument
“noise” rather than actual movement.
• There continues to be no measurable movement of points along Burma Road,
located just north of the mapped boundary of major landslide movement (2023 -
2025) and downslope from recent movement occurring in Rolling Hills in the Flying
Triangle Landslide, as well as areas of Cinchring Road and Quail Ridge Road. This
lack of measurable movement continues to support a hypothesis that the Altamira
Complex and the landslide(s) further north-northeast in Rolling Hills, portions of
which continue to creep, are not directly structurally connected.
• There continues to be no measurable movement of GPS points located outside of
the mapped Greater Ancient Altamira Landslide Complex/Ancient Portuguese
Bend Landslide Complex, including at Abalone Shoreline Park, in the Island View
tract, at the top of Burma Road, at the west end of the former Livingston Quarry
area (Forrestal), and in the Seaview Tract.
Table 1 on the following page provides a summary of movement rates for each sub-slide
over time.

Open Space, Palos Verdes Nature Preserve, Trails, and Beach Conditions
Out of concern for public safety and in consultation with the City Geologist, the City
Manager has temporarily closed much of the Portuguese Bend, Filiorum, and Abalone
Cove Reserves (subareas of the Palos Verdes Nature Preserve) including approximately
16 miles of passive recreational trails. The City Manager has also temporarily closed
Abalone Cove Beach, Sacred Cove Beach, and the beach below the Archery Range (east
of Inspiration Point) in close coordination with the City Geologist, Los Angeles County
Lifeguards, and the California Coastal Commission. Staff continue to monitor these and
other areas, and extensive repairs will likely be needed before these trails and open space
areas can be reopened for public use after the area has been stabilized.
Emergency Stabilization Activities
DDW Program Status
The DDW component of the emergency stabilization funded by the City Council, inclusive
of test boreholes and monitoring wells, is complete. Figure 3 shows the location of the
DDWs, test boreholes, and monitoring wells.
[Continued on Next Page]
11
Figure 3: Deep Dewatering Wells
Following are key notes regarding specific DDWs:
The total combined water extraction rate of the DDWs is currently approximately 600
gallons per minute or 0.86 million gallons per day.
• Since the start of the DDW program, approximately 306 million gallons, or 940 acre-
feet of water have been extracted.
• DDW-5 has sheared due to land movement. The City’s Geologists are evaluating the
potential for re-drilling or re-locating this well. Funding for this and other DDW activities
comes from FY2025-26 DDW maintenance and operations funds approved by the City
Council as part of the FY2025-26 Capital Improvement Program (CIP).
• DDW-7 has sheared, and based on its low production rate, the City’s Geologists are
advising that the well be re-located rather than re-drilled in its approximate existing
location.
• DDW-8 has sheared due to land movement. Re -drilling is underway and should be
complete shortly.
• DDW-9A has sheared due to land movement. Redrilling is scheduled to begin
following the completion of re-drilling DDW-8.
• DDW11 sheared and based on the low production rate, the City’s Geologists are
advising that this DDW should not be re-drilled, but rather re-located, should additional
funding become available. Due to the significant cost of relocating this DDW,
considered to be well above maintenance and operations, there are currently no plans
in place to relocate the well.

Underground water pressure measuring instruments, called vibrating wire piezometers
(piezometers) were installed to assist in determining the effects of DDWs on reducing
high water pressures, including locally artesian pressures, that might be contributing to
accelerated landslide movement.
Five monitoring wells with piezometers were installed at the locations shown in Figure 4
on the following page. The piezometers were installed under the deep slip plane as well
as under the shallow slip plane to measure uplift pressure on each slip plane. Additional
monitoring wells with piezometers were considered but not installed so that more of the
limited funding amount could be directed towards landslide stabilization activities.

Chart 1 shows water pressures from the piezometers installed under the deep slip plane
and Chart 2 shows water pressures from the piezometers installed above the deep slip
plane and below the shallower slip plane. The charts show water pressure from the time
the piezometers were installed until the present time, or until they stopped functioning
due to landslide shearing. Pressure on the plots has been converted to equivalent feet of
water pressure.

decrease in pressure immediately following the start of the DDW program . The surviving
piezometer, P-2, continued to show a marked pressure drop over time, which correlates
to reduced surface movement in nearby GPS survey points. There has been a slight
uptick in pressure between June and the beginning of August; most likely due to well
pump maintenance and sporadic downtime.
The piezometers far away from DDWs (E-2-2 and E-2-5) show only a slight, but somewhat
continuous decrease in pressure over time. The slight reduction shown in piezometer E-
2-2 and E-2-5 is likely the result of drying conditions and below normal rainfall. It is notable
that the drop in pressure for piezometer P-2 where there is water pumping reached almost
twice the drop in pressure for piezometer E-2-5 where there is no water pumping.
Emergency Winterization Status
Preparations for the 2025-26 rainy season have started with field reconnaissance by
geologists. The information from the field-reconnaissance will be used to prioritize
improvements and repairs, as constrained with the approved winterization budget in the
FY 2025-26 CIP.
ACLAD Update
Following is the status of ACLAD’s activities as of August 11, 2025. Figure 5 shows the
locations of the ACLAD dewatering wells.
• 6 original/shallow wells are operational and extracting water at a rate of
approximately 114 gallons per minute.
• 10 DDWs are operational and extracting water at a rate of approximately 318
gallons per minute.
• ACLAD pumped 6.8 million gallons in the month of July 2025.
• Drain wells do not operate during the evening hours due to the use of generators.
• Drain line connections for an additional 2 DDWs have been completed.
• 2 Monitoring Wells with piezometers have been installed.
• Various repairs and drainage line improvements have been completed.
ACLAD installed piezometers in the vicinity of their DDWs to collect data on the impact of
the DDWs on high water pressures, including local artesian pressures, that might be
contributing to accelerated landslide movement. Two monitoring wells with piezometers
were installed at the locations shown in Figure 5. The piezometers were installed under
the deep slip plane as well as under the shallow slip plane to measure uplift pressure on
each slip plane.

Figure 5: ACLAD Dewatering Wells with Water Pressure Measurement Instrument Locations
The City’s consultant engineering geologists, in coordination with ACLAD, reviewed the
data from the piezometers and prepared charts to show water pressure over time. Charts
3 and 4 show water pressure from the time the piezometers were installed until the
present time. Pressure on the plots has been converted to equivalent feet of water
pressure.

Chart 3: ACLAD Deep Slip Plane Water Pressure
Chart 4: ACLAD Mid-Deep Slip Plane Water Pressure
These plots show a positive, strong correlation to pressure drops at the slide planes after
the initiation of the ACLAD DDW program (beginning on 6/24/25) and a more positive
correlation to initiation of specific DDWs that are closest to the piezometer locations. Staff
18
notes that although pumping near the piezometers has only been active within the last
month or so, the minimal amount of data already displays distinct drops in pressure from
the initiation of nearby pumping wells.
Additionally, the City has revised the partial (mid-month) GPS monitoring points to include
a number of points in the vicinity of the recent ACLAD DDW’s, to further the assessment
of ACLAD DDW effectiveness in slowing the land movement. A prominent deceleration
of ACL and Altamira monitoring points occurred from July 1 to August 5, (average
deceleration 20%) compared to June 3 to July 1 period (average deceleration 6%). This
is interpreted to be a response to ACLAD DDW’s coming online, specifically DDW21 on
6/23/25, DDW’s 25 through 28 on 6/24/25, DDW29 on 7/9/25 and DDW8 on 7/23/25. Of
particular note is a significant deceleration in movement velocity for GPS monuments
AB57, AB58 and AB59 from July to August, compared to other monuments. This
deceleration is illustrated in Chart 5 below, with the dashed lines depicting the steeper
(declining) slope of movement velocity for AB57, AB58 and AB59.

KCLAD Update
Following is the status of KCLAD’s activities as of August 12, 2025. Figure 6 shows the
locations of KCLAD dewatering wells.
19
• KCLAD Well 5’s pump is set at 110 feet below ground surface and is extracting 26
gallons per minute while maintaining a water level of 72 feet below ground surface.
This pump needs service and is scheduled to be pulled as soon as new KCLAD
Well 7 is put into production.
• KCLAD Well 6 has been returned to service following a period of shutdown due to
poor performance. The pump has been serviced and reinserted at a depth of 150
feet below ground surface. The reinstalled pump is currently extracting 190 gallons
per minute while maintaining a water level of approximately 88 feet below ground
surface.
• New KCLAD Well 7 is nearing completion of construction. Drilling has been
completed, and crews are now working on supporting infrastructure including
discharge lines and electrical power. The target pump depth will be 175 feet below
surface level. Work will be completed in the coming weeks.
• Repairs are also planned for KCLAD Well 3 and KCLAD Well 4, both shallow wells,
to bring them back into service.
• Weekly readings are uploaded to the KCLAD website (KCGHAD.org).

On May 23, 2025 the City Manager sent SCE CEO Steve Powell a letter requesting
reconsideration of land movement threshold to start restoring electric power to the PBCA
area. Additionally, it was requested that SCE consider bearing the cost of undergrounding
the relocated box loop to help with wildfire resilience and view impacts. SCE provided a
response to City Staff on May 30, 2025 declining to change their land movement threshold
(1 inch or less per week) in PBCA and declining to bear the cost of undergro unding their
relocation. The City will continue working with CPUC and SCE to advocate for restoring
electric power to the PBCA in a manner that aligns with public safety and community
needs.
As a separate item, City Staff and SCE have been working together to redesign and
relocate the temporary pole that SCE placed at the Ladera Linda Community Park. On
March 4, 2025, the City Council granted a 6 -month time extension for SCE to relocate
their power pole. During this time, City Staff and SCE have been focusing on finding an
agreeable circuit loop system that meets the needs of the community and SCE in the long
term. City Staff took the options to City Council on July 15, 2025, however, due to SCE
being unavailable to attend, City Staff requested the item to be continued for another 90
days to allow more time to coordinate with SCE. This item is now tentatively scheduled
for the September 16 City Council meeting.
Sanitary Sewer – Portuguese Bend Community
The sanitary sewer system in the PBCA is known as the Abalone Cove Sanitary Sewer
System (Ab Cove Sewer) and is owned, maintained, and operated by the City. Crews
continue to regularly inspect the sewer lines and make repairs as breaks are identified
through inspections or resident notification. As noted above, the City’s sewer system is
normally energized by SCE and is currently using generators to maintain operations while
power is shut-off in the PBCA.
Sanitary Sewer – Seaview Neighborhood
The sanitary sewer system in the Seaview neighborhood is maintained and operated by
the Los Angeles County Public Works Department (LACPW), which has been inspecting
23
the sewer system, on an as-needed basis, in areas affected by the landslide. LACPW has
reported some localized settling; however, this has not been to a level necessitating
repairs.
Sanitary Sewer – PBBC
The sanitary sewer system in the PBBC is privately owned, operated, and maintained
and discharges into the Los Angeles County Sanitation Districts (LACSD) sewer trunk
line on PVDS. LACSD have been coordinating with the PBBC, so that the sewer line
integrity is maintained. It should be noted that this sanitary sewer system is also powered
by SCE.
Sanitary Sewer – Palos Verdes Drive South Trunk Lines
The sanitary sewer trunk lines adjacent to Palos Verdes Drive South (PVDS) are owned,
maintained, and operated by the Los Angeles County Sanitation Districts (San Districts).
Due to continued ground movement, the San District is currently replacing the inflexible
steel pipe with flexible high density polyethene pipe to both increase the force main’s
resilience to ground movement and to provide more effective redundancy preventi ng
single points of failure. Construction is scheduled to minimize impacts on traffic to the
extent possible, which includes overnight work for certain activities. The replacement
project is now expected to be complete by the end of summer 2025.
A sewer spill from the San Districts’ above-ground sewer trunk pipe occurred on July 23,
2025 along the south side of PVDS, near the area known as the “ski jump”. The spill
occurred at a pipe sleeve (designed to allow some movement of the sewer trunk pipe)
because landslide movement was higher than anticipated. The spill traveled across the
road to an isolated low-lying area on the north side of PVDS to the west of Peppertree
Drive. San Districts staff cleaned and recovered the spill along the road, with the majority
of the flow gathering at the low-lying area, which was raked to remove any wastewater
debris. The spill did not enter any storm drains that could reach the ocean. Pipe restraints
will be added to the pipe sleeve to limit movement and minimize the likelihood of future
spills.

Cost of FY 2024-25 DDW and Winterization Emergency Stabilization Measures
The City Council approved funding for the installation, operation, and maintenance of
DDWs as well as winterization at the project-level as described in the Fiscal Impact
section of this report. To provide a full disclosure of costs to date in the interest of
increasing public transparency, Staff are providing a more detailed accounting of
expenditures to include the specific cost for each DDW and winterization area by major
component. The figures presented in the report are preliminary and there may be min or
adjustments once all accounts are reconciled. The costs include all work completed
through June 30, 2025 under previously appropriated budgets.
DDW Installation
To calculate the cost of each DDW, there were expenses for certain activities not
attributable to one individual DDW, but that needed to be assigned to certain DDWs to
properly distribute costs. These activities include test boreholes installed in advance of
DDWs to obtain subsurface geological information on the depth, size, and angle of the
landslide slip plane to inform the design of the DDWs including location, depth, materials,
and equipment. Additionally, these activities include the construction of access roads so
that construction equipment could reach test borehole and DDW sites. To assign costs
for these activities, the relative proximity of each test borehole and resulting benefit for
the design of a DDW was determined as shown in Figure 7. Accordingly, the cost for each
test borehole was distributed to the benefiting DDW(s).
Next, the cost of equipment, labor, and materials used to install and commission a DDW
was calculated. These costs are primarily proportional to the depth of each DDW as well
as the magnitude of site development needed such as access paths, equipment pads
26
and ground stabilization. It is noted that DDWs 1 through 6 share most of the same
mechanical infrastructure due to their relative proximity to each other, which results in a
lower equipment cost per location.
Finally, professional services costs were calculated. These include engineering geology
to design the test boreholes and DDWs, geologist monitoring and guidance during
installation, and geologist interpretation and recommendations of operational and
maintenance information of the wells to optimize and report on their performance. Also,
construction management and inspection services were needed to coordinate the
logistics of construction, analyze cost proposals against industry averages, manage
construction schedules, and administer contracts. Additionally, a lthough the work was
performed in accordance with the City Council’s active state of local emergency
declaration relating to the land movement in the Landslide Complex, there remain ed
applicable federal and state regulations, as well as the City’s Natural Community
Conservation Plan / Habitat Conservation Plan (NCCP /HCP); requiring the project’s
compliance, reporting, and monitoring during construction with regards to environmental,
cultural, and tribal resources potentially affected by the work.
The various component costs for each DDW are presented in Table 3.

DDW Operations and Maintenance
Following their installation and commissioning, each DDW entered an operations and
maintenance phase. This phase consisted of operating, maintaining, and monitoring the
performance of the submersible pumps, discharge line(s) and power source. The cost of
this phase through Fiscal Year 2024-25 is presented in Table 4 on the following page.
Each DDW was inspected approximately 3 times per week to ensure each well was
extracting groundwater at an optimal well depth and rate, and to identify any maintenance
work proactively to reduce unexpected shutdowns. Due to the DDWs’ distance from
existing sources of power, generators were rented and refueled on a regular basis to
provide continuous power to each DDW pump.
Since the initial date of commissioning of the first DDW, land movement impacted overall
extraction rates, and in some cases rendered many DDWs inactive. As a result, a total of
13 re-drills were performed under the design and recommendations of the Project’s
Geologist, Geo-Logic Associates, Inc. (GLA), and peer-reviewed by CSA. The cost of re-
drilling and instances of re-drills at each DDW location is attributable to their overall run
time since their initial date of operation, the relative rate of land mo vement within the
general area of each DDW, and the ease of re-drilling a DDW in relation to any subsurface
obstructions such as the existing well casing, unrecoverable pumps and connecting
piping. As further described in the DDW status update above, DDWs 11 and 7 were de-
commissioned rather than being re-drilled due to relatively low extraction rates during
their operational runtimes.
While the magnitude of cost associated with professional services is significantly lower
than that during DDW installation, the above -described regular monitoring of the DDWs’
performance and implementation of remedial measures such as pump replacements and
re-drilling required the continued use of professional services. The same is applicable to
reporting on performance and impacts to land movement.
The groundwater extracted by each DDW is directly discharged to the ocean, and does
not require any pre-treatment before discharge. However, environmental compliance with
the current discharge system requires, at minimum, monthly water quality monitoring,
sampling and reporting to the regional and state Water Quality Control Boards. This cost,
28
along with other required environmental reporting, is also factored in the overall
expenditure.

Winterization
A summary of the costs to implement winterization measures within the Landslide
Complex is provided in Table 5 below. The work focused on preventing surface runoff
from infiltrating into the ground in the most impactful locations, which contributes to further
land movement. Typically, this was at the landslide boundaries and major fissures,
particularly those in canyons. The magnitude of work and relative cost to implement the
winterization measures generally correlates to the total area winterized in each location.
The work was performed as designed and recommended by the GLA and peer-reviewed
by CSA, with field modifications to fit budget constraints and localized conditions.
Construction of the winterization measures required construction management and
inspection as well as monitoring by GLA to assure conformance to the design intent and
recommendations. Similar to the DDW and exploratory borehole installations, a
consultant provided services to ensure the work conformed to applicable federal, state
and NCCP/HCP environmental compliance requirements. Finally, as with all other
activities, cost proposals were independently reviewed by a third -party consultant to
ensure consistency with industry pricing before being approved.

Ranked Order Priority List of Landslide Emergency Response Activity Costs
As part of the FY 2025-26 budget process, the City Council directed staff to present a
priority list of landslide emergency response projects/activities totaling $9 million so that
the City Council may consider future budget reductions based on the priority order rank
list.
To prepare a line-item version of estimated costs; Staff analyzed the actual operations
and maintenance cost of each DDW, or group of DDWs where there are shared
components, from the time of installation to the end of Fiscal Year 2024-25 as
summarized in the previous section. The trends for fuel consumption, re-drilling rates, and
other maintenance activities were applied to a full fiscal year. The resulting estimated
annual operations and maintenance costs are presented in Table 7. The same
methodology was applied to emergency winterization activities, which is presented in
Table 8.
Although the total cost of DDW operations in FY 2024-25 are comparable to the estimated
costs in FY 2025-26, they are not identical for the following primary reasons:
• Since the buildout of the DDW program was not completed until approximately the
mid-point of FY 2024-25, the respective runtimes for each DDW and associated
operations and maintenance costs, including re-drills did not span the full fiscal
year cycle as compared with the estimated costs for FY 2025-26, which project the
DDW program to be fully operating for the entire duration of the fiscal year; with
the exception of DDW-11 which has been decommissioned and therefore not
included in the estimated operations and maintenance cost for FY 2025-26.
• As of July 1, 2025, the City is directly contracting with companies for the various
operations and maintenance services without the use of a general contractor to
coordinate or perform these services, resulting in greater efficiency in performing
the work with and relatively lower costs.
Similar comparisons for the total cost of the winterization program in FY 2024 -25 and
estimated costs for FY 2025-26 can be made. The primary reasons for their differences
in cost are as follows:
• Winterized areas such as Klondike Canyon and the Seaview Neighborhood are
largely in-tact, resulting in less work and relative cost to keep these areas
winterized in FY 2025-26.
30
• The areas anticipated for winterization work in FY 2025 -26 are within existing
winterized footprints, which reduces the scope of related professional services to
ensure environmental and regulatory compliance.
• The above reductions in anticipated work and relative estimated costs are partially
offset by the scope of work anticipated to safely access and repair areas within
Altamira Canyon, Kelvin Canyon, and connecting tributaries that were winterized
in FY 2024-25 but have since been damaged by land movement.
The GPS surveying associated with the emergency stabilization efforts are not directly
attributable to a specific element; therefore, that cost is presented separately. Finally, due
to the uncertainty associated with rapidly changing landslide conditions, a minor
contingency is also included. Those costs were added to the DDW and winterization totals
and presented in Table 9.

Contingency $200,000
Total FY2025-26 $8,050,000
To prepare a priority order ranked list of the emergency response items, Staff asked the
project geologist, GLA; as well as the City’s contracted peer review geologist, CSA, for
their technical recommendations. Below is the technical reasoning provided by the
geologists for determining which elements of the program are most important, given
constrained resources.
The geologists have stated that DDW program is more important than the winterization
program because it directly affects known areas of high groundwater pressure, at various
depths, which is the primary cause of landslide movement.
Within the DDW program, following are the geologists’ recommended ranking priorities
(highest to lowest):
1. DDW-1, DDW-2, and DDW-3 because they represent part of a cluster that has had
the most impact on the Landslide Complex in terms of reducing land movement in
the KCL to below instrument error and in the PBL to one to two inches per week
locally. These three DDWs together would still provide notable benefit, although
not to the same extent as the entire set of DDWs in the area.
2. DDW-9A and DDW-10 because although they have shown less impact on the
Landslide Complex than the DDWs closer to the KCL, they still provide a breadth
of benefit, i.e. in the other areas of the Landslide Complex, that would not otherwise
exist.
3. DDW-5 because without it, there would still be a cluster of three DDWs nearby ,
which is not as effective as four or more DDWs, but would still provide some
benefit.
4. DDW-8 because it is isolated and less impactful than a group of wells.
5. DDW-7 because it is isolated and less impactful than a group of wells.
6. DDW-4 because without it, there would still be a cluster of four DDWs in the
general area, which is not as effective as five or more DDWs, but would still provide
some benefit.
7. DDW-6 because without it, there would still be five other DDWs in the general area
and those five DDWs would provide a substantial benefit, although not to the same
extent as is currently the case with six DDWs.
Within the winterization program, following are the geologists’ recommended ranking
priorities (highest to lowest):
32
1. Altamira Canyon because it has the newest fissures where runoff infiltration can
occur as compared to other areas where the FY 2024 -25 winterization program
will still provide a benefit.
2. Kelvin Canyon; for the same reason as Altamira Canyon; however, Kelvin Canyon
is a lower priority than Altamira Canyon because Altamira Canyon carries more
flow.
3. Klondike Canyon because most of the FY 2024 -25 winterization work remains
intact. However, based on lessons learned from the FY 2024 -25 winterization
program, there remain erosion control needs as well as vulnerabilities in the
Klondike Canyon liner that should be better secured.
4. Fissure filling on City land throughout the Landslide Complex because there are
new fissures since the FY 2024-25 winterization program.
5. Seaview neighborhood because most of the FY 2024 -25 winterization work
remains intact.
The total estimated cost of the DDW and winterization programs for FY2025-26 is less
than $9 million; therefore, additional landslide projects are added to the priority order rank
list. Below is the reasoning for determining the priority order of the additional projects
(highest to lowest):
1. Palos Verdes Drive South Landslide Repair Program (CIP 8302) because this
important arterial roadway provides access for emergency services to several
neighborhoods, is the evacuation route for the south side of the City, is a main
thoroughfare for commercial centers in the City, and carries traffic (approximately
15,000 daily trips) that would otherwise create congestion on Palos Verdes Drive
East, Palos Verdes Drive North, Hawthorne Boulevard, and Western Avenue.
2. Abalone Cove Sanitary Sewer Repair Program (CIP 8202) because an operational
sanitary sewer system is necessary to avoid red-tagging of additional homes.
3. GPS Surveying because without a robust data collection program, the behavior of
the Landslide Complex and any mitigation measures could not be properly
scientifically analyzed.
4. PBL Hydrology & Hydraulics Study (CIP 8309) because this study is essential to a
complete understanding of the Landslide Complex, which leads to the most
efficient and effective solution.
5. PBL DDW1-6 Permanent Power (CIP 8308) because providing permanent power
to DDWs significantly reduces their operational costs. Additionally, 75% of the cost
of this project is funded by a federal grant.
6. PBL Remediation (CIP 8304) because although the design phase of this project
currently has approved federal funding, there remains a significant gap in the total
construction funding needed.
Based on the technical recommendations of the geologists, and other considerations,
below in Table 10 is the overall priority order list of the landslide activities and associated
costs (highest to lowest).

amount. The total budget, including the Federal Grant, for landslide activities is $17,750,000.
The City Council is being asked to review the above ranked priority order list of costs
associated with the FY 2025-26 DDW and winterization programs.
Financial Update
Expenditures to Date and FY 2024-25 Draft Year-End
Overall, the City’s estimated expenditures for the Portuguese Bend Landslide from
October 2022 through June 2025 are approximately $48 million including continuing
appropriations and Purchase Order (PO) carryover from FY 2023-24 approved on
January 21, 2025.
As shown in Table 11 on the following page, year-to-date expenditures and
encumbrances have increased from $33.1 million, as reported on July 1, 2025, to $36.8
million. This figure is preliminary and subject to change, pending the Finance
Department’s completion of the year-end closing process over the next few months, which
will incorporate services provided by June 30, 2025.
Overall, compared to FY 2023-24, the projected $36.8 million for FY 2024-25 represents
a 294% increase. These costs include emergency response and stabilization efforts such
as test boreholes, deep dewatering wells, maintenance of the deep dewatering wells,
winterization, fissure filling, road repairs, sewer repairs, estimated time and costs for
personnel dedicated to the project, legal services, loans to ACLAD and KCLAD, in-kind
support to ACLAD, and increased tax assessments borne by the City.

FY 2025-26 Adopted Budget
On June 17, 2025, the City Council adopted the FY 2025-26 Budget which includes
$17,750,000 of Portuguese Bend Landslide projects, as summarized in the Fiscal Impact
page (page 2 of the report). Of this amount, almost $13.7 million is funded by the CIP
Fund and $4 million from Special Revenue (Restricted) Funds. Additionally, the FY 2025-
26 budget includes $860,000 for property tax assessment fees paid to KCLAD and
ACLAD, funded by the General Fund.
Since the fiscal year just began, as of July 31, 2025, the total expenditures are $22,145,
with additional $2,151,855 encumbered, representing 16% of the total budget (Tables 11
and 12). As shown in Table 13, the City has also paid $860,300 in tax assessments,
representing 100% spent of the total budget in assessments, as these payments were
due in July.

ACLAD/KCLAD Loans $3,527,500
On August 20, 2024, the City received signed loan agreements from ACLAD and KCLAD
in the amounts of $1.6 million and $1.9 million, respectively. As of April 3, 2025, both
loans have been fully disbursed, totaling $3.52 million, in accordance with the loan
agreements. The loans have a 12-year term with a 2.5% interest rate, and the first
estimated payment is scheduled for December 2026.
Per the agreements, the funds will be used to stabilize land movement, including the
installation of dewatering and monitoring wells, system improvements, surface drainage
enhancements, grading, and infilling of fractures. Tables 14a and 14b below are a
summary of expenditures that were used for the loan ending July 2025. Financial
information was provided by the districts.
For ACLAD, as of July 31, 2025, $1,447,895 or 90% have been spent (Table 14a).
Majority of the loan amount (99%) was used for maintenance and operations. Of the 99%
in maintenance and operations, 60% was used for well drilling and 38% was general
operations such as generators, supplies, and well repairs. In accordance with the loan
agreement, no expenditures were made on legal services. Legal service expenses
incurred by the District were paid from their annual operating budget.
Table 14a: ACLAD – Summary of Expenditures for the City Loan of $1,610,000
As of July 31, 2025, KCLAD spent $709,543 or 37% of the loan (Table 14b). Majority of
the loan amount (95%) was used for maintenance and operations, and 5% used for
contract services for consulting and geology. Of the 95% of maintenance and operations,
approximately 74% was for pipeline maintenance. In accordance with the loan
agreement, no expenditures were made on legal services. Legal service expenses
incurred by the District were paid from their annual operating budget.

BRIC and HMGP Grant Update
On April 15, 2025, CalOES notified the City that California along with other states received
notification through a FEMA Advisory, that FEMA is discontinuing the Building, Resiliency,
Infrastructure, and Community (BRIC) program; through which the City had been selected
for $23.3 million in grant funds (with a required $10 million non-federal match) for the PBL
Remediation Project, later revised to $16.4 million (with a required $7 million non -federal
match) due to overlapping emergency stabilization work.
The notification further stated that FEMA Regions will work with applicants to end their
BRIC projects after the completion of Phase 1, for which the City has already been
awarded approximately $2.3 million (with a required non -federal match of approximately
$700,000) or at another appropriate stopping point. Staff have been verbally informed by
FEMA that the Phase 1 grant award will not be withdrawn, and Staff are seeking written
confirmation.
In consideration of the FEMA Advisory, the City submitted a Notice of Intent (NOI) to apply
for FEMA’s Hazard Mitigation Grant Program (HMGP) for the PBL Remediation Project
to cover a similar scope as the BRIC grant project, expanded based on current conditions.
The City was notified by CalOES that the NOI was reviewed by CalOES and determined
to represent an eligible HMGP activity; therefore, the City may now move forward with
submitting a grant application by September 15, 2025 for funding consideration.
The grant requires non-federal matching funds of 25%. The cost estimate of the revised
scope of the PBL Remediation Project, expanded based on current conditions, is $40
million; which means that the required non-federal match is $10 million. Based on the
City’s fund balance status, the only currently available source of matching funds is from
the unallocated fund balance in the General Fund. According to projections presented at
the FY 2025-26 budget workshop, the General Fund is expected to end the year with a

$27.3 million balance, of which $17 million is held in reserves and $10.3 million
unallocated. For cash flow purposes, staff anticipates that the $10.3 million will be needed
to support the FEMA Voluntary Property Acquisition Buyout Program, with reimbursement
expected within the same fiscal year. Therefore, should the City Council elect to allocate
the $10 million match from the General Fund for the PBL Remediation Project, the timing
is anticipated to be reasonable, as the project is expected to be a multi -year project.
Staff seek City Council approval to submit the grant application with a commitment for a
$10 million match from the unallocated fund balance in the General Fund. Should the City
Council approve submittal of the grant application, Staff will return to request that the City
Council accordingly adopt a resolution to that effect.
Design Services for the PBL Remediation Project (CIP 8304)
The original PBL Remediation Project design was nearing completion in early 2024.
However, known site conditions of the PBL have changed dramatically since that time to
an extent resulting in the city implementing emergency landslide stabilization measures
through the installation of several DDWs and winterizing areas within the Landslide
Complex as part of a separate project (CIP 8307). As such, modifications to the scope
and final design of CIP 8304 (as part of Phase 1 described in the Fiscal Impact and Grant
Update sections above) are necessary to be reflective of the existing conditions of the
PBL and the relative stabilization measures currently in place across the Landslide
Complex.
A concept plan for the project has been developed and is generally based on the
conceptual comprehensive build-out presented to City Council on January 21, 2025 , but
limited to the PBL boundary.
In response, staff solicited a proposal from GLA to prepare final plans, specifications,
construction documents and associated permits and environmental documents reflective
of the current site conditions (Attachment H).
On July 3, 2025, Cal OES formally approved the City’s request for a noncompetitive
procurement of a contractor (GLA) for professional services, including geology,
engineering, environmental studies, grant administration and similar services to complete
the Phase 1 scope of work. The approval is justified by the emergency conditions within
the Landslide Complex requiring immediate actions to stabilize land movement and
infrastructure that cannot be delayed by a competitive procurement process.
Staff evaluated GLAs proposal (Attachment G) and negotiated a scope, schedule and fee
as part of the proposed professional services agreement (PSA) (Attachment F).
Accordingly, Staff recommend that the City Council approve a PSA with GLA to complete
the final engineering and design of the project. A summary of the scope of services is as
follows:
Scope of Services:
• Prepare all studies, investigations, analyses, and reports necessary to inform the
preparation of construction documents specifying improvements to mitigate the
PBL to a negligible rate of movement and provide long-term protection from
39
recurring landslide activity including from future intense and prolonged rainfall
events by addressing the root cause of the landslide.
• Prepare construction drawings/plans, specifications, and any other documents
necessary for a construction contractor to construct the proposed improvements.
• Develop comprehensive cost estimate of the proposed improvements

initial field reconnaissance and study phase. The approved FY 2025-26 CIP includes
funding for the scope of services in the amount of $700,000 from the CIP Fund
(Attachment I). The Grant Funding section above provides information regarding how the
CIP funds allocated for GLA’s proposed scope of services are associated with staff’s
ongoing pursuit for securing grant funding.
If deemed acceptable, the City Council is being asked to award a PSA to GLA for final
engineering design, environmental documents, and related services for the PBL
Remediation Project (Capital Improvement Project (CIP) 8304) in the amount of $460,685
with a contingency of 15% or $69,103
Bicycle, Motorcycle, Unicycle and Other Similar Wheeled Vehicle Prohibition
Since the City Council’s declaration of a local emergency, the City Geologist has been
regularly reviewing survey data and conducting field observations of PVDS in the
Landslide Complex. While the City’s Geologist reports the rate of land movement has
slowed, there remain areas of PVDS where land movement is two to three inches per
week. Overall, pavement conditions on PVDS remain very poor, with cracks, bumps,
fissures, and other irregularities. Deformations in the pavement can occur overnight.
On July 26, 2025; a sinkhole formed overnight in the southbound lane of PVDS near the
area commonly known as the “ski jump” between Narcissa Drive and Peppertree Drive.
40
Repair of the sinkhole required a full closure of PVDS for several hours, and a partial
closure for several more hours.
Although four-wheeled vehicles (i.e. cars) can, with due care, navigate the road when it
is open, the impact on one- and two-wheeled vehicles remains pronounced. Despite the
added signs prohibiting bicyclists, motorcyclists, unicycles and other similar wheeled
devices from traversing the landslide, there remain those who ignore the prohibition at
their peril. Were the City Council to end the current prohibition, the Office of the City
Attorney remains of the considered legal opinion that permitting one- or two-wheeled
vehicle traffic across the landslide will pose a liability risk to the City and that the same is
not presently safe for these vehicles to travel on PVDS, even using due care, across the
landslide for the reasons noted above.
Since the Emergency Declaration on October 3, 2023, there have been three claims filed
prior to the Bicycle, Motorcycle, Unicycle and Other Similar Wheeled Vehicle Prohibition.
The declaration of emergency, together with the repeated warnings about roadway
conditions, has resulted in the City successfully defending claims in court for damage to
vehicles where drivers have ignored the declaration and City warnings.
Based on these recent claims and roadway conditions, Staff and the City Attorney
recommend extending the existing resolution prohibiting one - or two-wheeled vehicles on
PVDS for an additional 60 days (Attachment A).
With respect to vehicle damage claims, the declaration of emergency, together with the
repeated warnings about roadway conditions, has resulted in the City successfully
defending claims in court for damage to vehicles where drivers have ignored the
declaration and City warnings.
Extension of the Local Emergency Declaration
On October 3, 2023, the City Council adopted Resolution No. 2023-47 declaring a local
emergency. The emergency declaration is deemed to continue to exist until its termination
is proclaimed by the City Council in accordance with law. Government Code § 8630
requires the City Council to review the need for continuing the local emergency at least
once every 60 days until the City Council determines the local emergency within the
geographic boundaries of the Landslide Complex has been abated or mitigated to
insignificance.
The City Council has extended the local emergency on multiple occasions within the 60 -
day window and it remains in effect until August 30, 2025, unless extended again this
evening. At this time, the City Council is being asked to extend the local emergency
declaration an additional 60 days through October 18, 2025, which does not require a
public hearing. If extended this evening, the Council would consider renewing the local
emergency declaration again during the next landslide update on October 7, 2025. The
City Council is being asked to adopt the attached resolution thereby extending the
Declaration of Local Emergency by 60 days (Attachment B).
41
Extension of the Local Emergency Declaration for Utility Shutoffs
On August 6, 2024, the City Council adopted Resolution No. 2024 -52 declaring a local
state of emergency because of a sudden and severe energy shortage caused by shutting
off natural gas service to approximately 135 homes in the PBCA due to safety concerns.
On September 3, 2024, the City Council adopted Resolution No. 2024-57, declaring a
local state of emergency because of a sudden and severe energy shortage caused by
shutting off of natural gas service, planned de-energization events, and internet shut-offs
in the PBCA, Seaview, and PBBC neighborhoods. The emergency declaration is deemed
to continue to exist until its termination is proclaimed by the City Council in accordance
with law. Government Code § 8630 requires the City Council to review the need for
continuing the local emergency at least once every 60 days until the City Council
determines the local emergency because of a severe energy shortage has been abated
or mitigated to insignificance.
The City Council has extended the local emergency declaration for utility shutoffs on
multiple occasions within the 60 day window and it remains in effect until August 30, 2025,
unless extended again this evening. At this time, the City Council is being asked to extend
the local emergency declaration an additional 60 days through October 18, 2025, which
does not require a public hearing. If extended this evening, the Council would consider
renewing the local emergency declaration again during the next landslide update on
October 7, 2025. The City Council is being asked to adopt the attached resolution thereby
extending the Declaration of Local Emergency due to a severe and sudden energy
shortage by 60 days (Attachment C).
ADDITIONAL INFORMATION:
Continuing the Emergency Work and Emergency Contract
As a separate item on tonight’s agenda, the City Council is being provided with an update
on the Portuguese Bend Landslide Emergency construction contracting and being asked
to reconfirm the need to continue the emergency work. This is a recurring agenda matter
and requires a 4/5th vote.
Study to Create a Toll Road on PVDS
On January 21, 2025, the City Council directed staff to pursue alternative or additional
funding sources for landslide remediation and management efforts. Subsequently, the
City Council directed Staff to analyze the possibility of converting PVDS to a toll road,
including potential revenue and cost, feasibility, as well as potential unintended
consequences such as diverted traffic.
In accordance with the City Council’s direction, Staff reached out several firms that work
with other municipalities and state departments of transportation on tolling operations and
requested proposals for a high-level feasibility study of tolling PVDS. Two firms have
provided proposals. Staff reviewed the proposals and will present a proposed
professional services agreement for a toll road study for the City Council’s consideration
at the September 2, 2025 City Council meeting. Additionally, Staff will provide other
relevant information for the City Council’s consideration such as legal requirements and
Coastal Commission jurisdiction.
42
Wayfarers Chapel Slope at PVDS
Material from the Wayfarers’ Chapel slope adjacent to PVDS was sloughing off into the
shoulder and second travel lane of PVDS. The shoulder and second travel lane were
closed and a concrete barrier was installed to protect the remaining travel lane from falling
debris. In recent weeks, the City Geologist expressed concern that the risk for more
significant sloughing, which could impact the last remaining travel lane, has increased.
Therefore, Staff requested that Wayfarers Chapel re-shape its slope, in coordination with
the City Geologist, to minimize the risk of debris going into the last remaining travel lane
of PVDS. Around July 21, 2025, a Wayfarers Chapel contractor began re-shaping the
slope, with monitoring by CSA. The work continues and is expected to conclude in
approximately 2-3 weeks.
Permanent Power to DDWs 1-6
The approved FY 2025-26 CIP includes a project for the engineering, design, and
construction for connecting DDWs 1 through 6 to a permanent power source, effectively
eliminating the use of diesel generators to power these DDWs. The approved budget
anticipates funding 75% of the project with a grant being sought through CalOES and
FEMA with 25% city-matched funding. Proposals are currently being solicited for the
engineering and design phase of the project. This phase is anticipated to be completed
by December 2025. Construction is anticipated to commence shortly thereafter and be
completed by September 2026.
Abatement of 4361 Exultant Drive Structure
The City’s Community Development Department is abating red-tagged structures, as a
public nuisance, on property located at 4361 Exultant Drive. The abatement involves the
demolition of unsafe structures, overgrown vegetation, and other materials or debris on
the property.
The demolition of the structures will be conducted in compliance with the Southern
California Air Quality Management District (AQMD) regulations including a Procedure 5
(P5) asbestos plan. The P5 asbestos plan includes detailed procedures to safely manage
disturbed asbestos-containing materials to ensure regulatory compliance and to protect
public health and the environment. This includes the use of water to mitigate dust, in
compliance with the PF asbestos plan.
The AQMD review of the P5 asbestos plan has caused some delay in the initiation of
demolition activities, but permits are scheduled to be issued as of writing this report.
Demolition activities are anticipated to begin the week of August 18 and completed as
quickly as 2-3 working days, with the structure being removed in sections with the use of
equipment including, but not limited to, an excavator.
Once structures are demolished, general grading will be completed and fissures on the
property will be filled. There will not be public access to the site once the abatement is
completed, as the site will remain privately owned.
43
Area residents and the resident association have been briefed on the upcoming
abatement including measures to minimize impacts to the surrounding neighborhood.
Staff will continue communicating with the area residents and resident association leading
up to the scheduled abatement and during the abatement process.
Permanent Building Regulations for Greater Portuguese Bend Landslide Complex
On October 3, 2023, the City Council adopted Interim Urgency Ordinance No. 674U
pursuant to Government Code §§ 36937 and 65858 prohibiting new construction within
the Greater Portuguese Bend Landslide Complex, with the exception of actions
necessary to prevent or mitigate loss of, or damage to, life, health, property, or essential
public services. This moratorium was extended for an additional 10 months and 15 days
on November 14, 2023 with the City Council adoption of Interim Urgency Ordinance No.
675U, and again on September 3, 2024 by Interim Urgency Ordinance 686U, for a total
of two years. This moratorium has been extended to the maximum two -year life and is
set to expire on October 2, 2025.
At the August 5, 2025 meeting, City Council considered what actions to take to
permanently respond to the conditions that gave rise to the landslide moratorium in the
first instance. At that meeting, City Council introduced Ordinance No. 692 to repeal the
prior regulations of Chapter 15.20 and replace with proposed code amendments to
Chapter 15.20 of the RPVMC to address the impacts of the substantial change in
circumstances of the land movement, the unpredictability of future weather conditions that
may exacerbate movement, and the threat to loss or damage to life, health, property, or
essential public services. Such amendments include, among other items, prohibiting new
construction of single-family residences or additions to existing single-family residences,
as well as amending the Landslide Complex Map to correspond to the boundary limits of
recent land movement. The second reading and adoption of these regulations is on
tonight’s agenda, as a separate Consent Calendar item. If adopted, the new regulations
will go into effect thirty days later (September 18, 2025).
Under the regulations in the proposed ordinance, property owners in the landslide area
would be permitted to replace, restore, and repair development within its existing footprint.
Additionally, the boundaries of the landslide complex would be updated to co rrespond
with the expanded limits of recent land movement.
Disaster Cost Recovery Applications Update (FEMA and CalOES)
As previously included in the prior reports, in response to the declared federal disaster
for the winter storms that occurred between January 31 and February 9, 2024 , and the
Governor’s state of emergency for the indefinite de -energization of power, the City
tabulated the costs it incurred through September 12, 2024 for reimbursement
consideration by FEMA and CalOES. Table 16 summarizes the City’s requests for cost
recovery from CalOES and FEMA in the amount of $61.4 million. Of this amount, $39.4
million is public assistance (City) and $22 million of individual assistance (residents).
44
Table 16: Cost Recovery Applications
AGENCY COST RECOVERY TYPE DISASTER EVENT REQUESTED AMOUNT
In Millions
FEMA Public Assistance (City) Winter Storm (Jan/Feb 24) 38.4
CalOES Public Assistance (City) Energy Shutoff 1.0
CalOES Individual Assistance Energy Shutoff 22.0
TOTAL $61.4
As reported in previous staff reports, according to FEMA and CalOES, natural disaster
recovery funds will not be provided for landslide remediation efforts because it is
considered “pre-existing.” Out of the $39.4 million application for public assistance (City),
Staff is projecting only approximately $1.5 million in potential disaster recovery funds from
the Winter Storm and Energy Shutoff. If deemed eligible, the reimbursement process
could take anywhere from one to three years before the City receives the funds.
In July 2025, FEMA informed staff that the reimbursement request for protective
measures and debris removal, totaling approximately $596,000, has been approved and
forwarded to CalOES to initiate the funding process. Staff continue to coordinate with both
FEMA and CalOES to facilitate the reimbursement. A continuous update on the
reimbursement will be provided once the funding has been officially awarded to the City.
For the remaining recovery applications, as previously reported, on January 17, 2025, of
the $38.4 million applied for public assistance related to the winter storm, summarized
and shown in Table 17, the City received seven denial letters from FEMA, followed by an
additional denial letter on February 25, 2025 for a total of $37.9 million.
Pursuant to the Stafford Act and Code of Federal Regulations, the City has 60 days from
the Notice of Eligibility Determination to file an appeal. On March 17, 2025, the City filed
appeals of the first seven denial letters, and on April 25, 2025, the City filed a remaining
appeal letter. The appeal will be heard by FEMA’s District 9 Administrator, Robert Fenton,
and his decision is then appealable to FEMA’s Headquarters in Washinton D.C. To date,
the City has not received any response from the appeal letters filed aside from a
confirmation of receipt.
It should be noted that both ACLAD and KCLAD filed appeals as well for the denials they
received for disaster recovery assistance. Both ACLAD and KCLAD have received
notification from CalOES that they will not be recommending overturning the denial to Mr.
Fenton.
For the $22 million individual assistance (IA) application that the City submitted on behalf
of the residents, the City has been notified that these funds will not become available.

FEMA Voluntary Property Acquisition Buyout Program
On October 28, 2024, the City, FEMA and Cal OES announced a $42 million Voluntary
Property Acquisition Buyout Program (Buyout Program) for property owners in the
Landslide Complex whose homes have been damaged or threatened by land movement.
Established with funding from FEMA’s HMGP, which is a grant not disaster assistance,
the Buyout Program is intended to help eligible homeowners relocate to safer areas by
offering fair market value for their properties based on pre-disaster appraisals. Properties
acquired by the City through this Buyout Program will be permanently converted to open
space and deed-restricted, protecting the community from future redevelopment risks in
these vulnerable areas.
More information about the Buyout Program including, but not limited to, funding sources,
minimum eligibility requirements, application evaluation methods and program
participation requirements was previously made available as part of the February 4, 2025
City Council Staff Report related to updates and action items for the Landslide Complex.
As well, information on the Buyout Program may be found on the City’s website.
The City received 85 applications for the first round of program funding . After review for
eligibility and determining estimated costs for the prioritized properties based on the
program guidelines, the City has determined funding will be available for buyouts of 22
properties (13 red-tagged, and 9 yellow-tagged) in the first round of program funding. All
remaining eligible applications will be considered for any future rounds of program
funding.
On December 19, 2024, the City issued Requests for Proposals (RFPs) for appraisal
services, title companies, escrow professionals, and land surveyors related to the Buyout
Program. Submitted proposals were evaluated and professional service agreements with
selected firms were approved by the City Council on March 18, 2025.
In February 2025, the City’s Community Development Department notified 23 program
participants that their Buyout Program application was still active and being processed
for further evaluation. The notification letter requested that program participants schedule
a reinspection of their properties with the City’s Building & Safety Division and to submit
FEMA required processing forms. City Staff received the requested information and
completed the re-inspection of the 23 properties.
With the award of professional service agreements for Buyout Program services and the
completion of requested inspections and forms, City Staff connected program participants
with property appraisers in order to further implement the Buyout Program. As well, City
Staff authorized the preparation of the preliminary title reports for the 23 program
properties.
Appraisals were completed at the beginning of May 2025. On May 12, 2025 Property
owners received a copy of the appraisal and were provided the opportunity to appeal it.
As well, the City collected additional required forms and information for the program from
the 23 program properties in order to complete the response to FEMA’s Request for
Information (RFI) that was due on June 27, 2025. On June 2, 2025 one of the property
owners withdrew from the program. After reviewing the appraisal information for the
47
remaining 22 program properties and updating the application budget as part of the RFI
response, the first round funding would only be able to fund the acquisition of the
remaining 22 program properties.
City staff is working as quickly as possible to move through this lengthy and complex
process, which involves multiple levels of close review by FEMA. Each property must be
carefully vetted for compliance with program rules and regulations. In the coming weeks,
the City plans to onboard a consultant dedicated to managing the buyout program.
There is not a definitive timeline for when the first of the 22 properties may be purchased.
The City is still in the “pre-award” phase of the grant process with FEMA. Once the City
is formally awarded the grant, which could happen in at least several months from now,
the $42 million will come in installments, likely on a quarterly basis, which is standard
practice. The City will receive these payments as reimbursements only after the
transactions are completed in batches. For cash flow purposes, the program does not
provide advance payments. As such, staff anticipates that approximately $10 million will
be needed during the initial phase of awards to support the program while awaiting
reimbursements.
The Voluntary Property Buyout Program is funded by FEMA’s Hazard Mitigation Grant
Program (HMGP). This is different from FEMA’s Building Resilient Infrastructure and
Communities (BRIC) program, which was recently ended by the federal government and
may result in the City losing funding for a separate grant for the Portuguese Bend
Landslide (PBL) Remediation project. At this time, City staff has not been notified of any
changes to the status of the HMGP. The City has submitted a rolling application for
additional HMGP funding in order to potentially offer more rounds of the buyout program.
CONCLUSION:
Over the past four months the average movement velocity for the portion of the Landslide
Complex that is still moving accelerated slightly between February 3, 2025 and March 9,
2025, possibly in response to moderate rainfall that fell in this period. It the n decelerated
slightly between March 9, 2025 and April 5, 2025, and has decelerated considerably
between April 5, 2025 and June 3, 2025. Based upon a review of approximately weekly
readings of 20 select GPS monitoring points located mostly in the lower po rtions of the
Landslide Complex; with below-average rainfall conditions during the rainy season, in -
place winterization measures, and the ongoing dewatering effort, it can be concluded that
the:
• KCL has stopped moving.
• PBL was previously viewed as having reached a steady state of movement since
the end of October 2024; however, it continues to decelerate.
• ACL and upper Altamira Complex areas continue to decelerate.
• Fastest moving area remains the upper portion of the ACL at an average of 1.15
feet per month (about 3.2 inches per week); however, the area of the ACL moving
at this rate continues to shrink, most likely in response to recent deep dewatering
48
efforts by ACLAD. It is anticipated that this movement rate will continue to
decelerate as additional wells come online and dewatering production increases.
Using the City’s $1.6M loan,10 ACLAD DDWs are operational as of August 11, 2025, and
two monitoring wells have been installed. Additional DDWs are being considered in the
coming weeks, depending on available fund s. ACLAD estimates that the current
dewatering rate among all wells is approximately 432 gallons per minute (114 and 318
gallons per minute for shallow and DDWs, respectively). At this juncture, it is too early to
draw conclusions as to the efficacy of the ACLAD DDWs, particularly because some of
them only recently became operational and others are in the process of coming online.
Due to ongoing high rates of movement and associated impacts in certain parts of the
Landslide Complex, Staff recommend that the City Council extend the temporary
prohibition on one- and two-wheeled vehicles, extend the local emergency declaration,
extend the de-energization emergency declaration for an additional 60 days, approve the
submittal of a grant application to the FEMP HMGP for the PBL Remediation Project with
a $10 million match from the unallocated fund balance in the General Fund, and award a
PSA to GLA for final engineering design, environmental documents, and related services
for the PBL Remediation Project.
ALTERNATIVES:
In addition to Staff recommendation, the following alternative actions are available for the
City Council’s consideration:
1. Take no action, and receive and file this report.
2. Do not extend the temporary prohibition of one- or two-wheeled vehicles on PVDS
and allow one- and two-wheeled to begin using PVDS again.
3. Do not adopt one, or both, of the resolutions continuing the local emergency
declarations.

WHEREAS, the Greater Portuguese Bend Landslide Complex (the
Landslide Complex) encompasses four historically active landslide areas in the
City: the Portuguese Bend Landslide (PBL), the Abalone Cove Landslide (ACL),
the Klondike Canyon Landslide (KCL), and the Beach Club Landslide (BCL). It also
includes the Flying Triangle Landslide (FTL) in the City of Rolling Hills as mapped
by various agencies (i.e., U.S. Geological Survey, California Geological Survey)
and other researchers; and
WHEREAS, following the 2022-23 rainy season, the Landslide Complex’s
movement has accelerated exponentially. Therefore, on October 3, 2023, the City
Council of the City of Rancho Palos Verdes adopted Resolution No. 2023-047
based on its authority pursuant to Section 8610 et seq. and Section 8630 et seq.
of the Government Code, and Chapter 2.23 of the Rancho Palos Verdes Municipal
Code, declaring a state of local emergency for the Landslide Complex based on
the accelerated movement of the land. The declaration of emergency has been
renewed as required by law and currently applies; and
WHEREAS, following the City Council’s declaration of a local emergency,
the City experienced another record-setting rainy season; and
WHEREAS, since the City Council’s declaration of a local emergency, the
City Geologist, Mike Phipps of Cotton, Shires, and Associates, Inc. (CSA), has
been regularly conducting field mapping throughout the Landslide Complex;
observing conditions at various locations, and reviewing survey and rainfall data;
and
WHEREAS, the City Geologist most recently reported to the City Council
on May 7, 2024, in summary, that the Landslide Complex continues moving at
unprecedented rates, predominantly in response to the two consecutive seasons
of significantly above average rainfall; and
WHEREAS, the City Geologist stated that land movement continued to
manifest at the ground surface in the form of landslide scarps, fissures,
grabens/sinkholes, tensional cracking, shear zones and thrust features; and that
due to the continued acceleration, the ground movement features have continued
to enlarge, expand, widen, or grow depending on the type of feature and location,
A-1

Page 2 of 4
which also affects Palos Verdes Drive South (PVDS) as it traverses the Landslide
Complex area; and
WHEREAS, the City Geologist summarized that road conditions on PVDS
continue to be adversely impacted due to differential rates of land movement
ranging from about 5 to 8 inches per week, at the time of the report to the City
Council on May 7, 2024; and
WHEREAS, traffic signs on PVDS in the landslide area include various
signs warning of the landslide conditions, with some specifically directed at
bicyclists and motorcyclists. Out of an abundance of caution, Staff (through a
consultant), conducted a review of signs on PVDS. As a result, additional signs
were installed, including signs installed on June 1, 2024 specifically directed at
bicyclists and motorcyclists; and
WHEREAS, despite the existing bicycle warning signs, Staff has been
anecdotally informed of bicycle crashes, and at least one claim has been filed
against the City (which was prior to the additional bicycle and motorcycle signs
installed on June 1) and at least two claims for injury to persons or property have
been filed with the City; and
WHEREAS, Section 8610 of the Government Code provides the local
disaster council with broad powers to “develop plans for meeting any condition
constituting a local emergency or state of emergency, including, but not limited to,
earthquakes, natural or manmade disasters specific to that jurisdiction, or state of
war emergency….”; and
WHEREAS, Chapter 2.24 designates the City Council, the director of
emergency services, the assistant director of emergency services, and the chiefs
of emergency services as the City’s Disaster Council; and
WHEREAS, the director of emergency services (the city manager), “[i]n the
event of the proclamation of a local emergency […], the director [of emergency
services] is empowered: a. To make and issue rules and regulations on matters
reasonably related to the protection of life and property as affected by such
emergency….”; and
WHEREAS, the City Council finds that despite consistent and recently
increased signage, riders of bicycles and motorcycles continue to use PVDS, and
that the land movement is creating frequent localized deviations in the road, which
can be navigated safely in cars and trucks, but that are more dangerous for two-
wheeled vehicles such as bicycles and motorcycles; and
WHEREAS, the City Council finds that the safety of bicycle, motorcycle and
other two-wheeled riders is a compelling interest; and
A-2
Resolution No. 2025-__
Page 3 of 4
WHEREAS, the City Council finds that in order to further the City’s
compelling interest in the safety of riders, it is appropriate to temporarily route
bicycles and motorcycles away from the portion of PVDS within the Landslide
Complex, until such time as the City may be able to slow the land movement
sufficiently to reduce the frequency and severity of road deviations to minimize the
risk of injury to persons or property; and
WHEREAS, on June 18, 2024, the City Council duly adopted Resolution
No. 2024-39 prohibiting, for a period of six (6) months, bicycles, motorcycles, and
other two-wheeled vehicles from traversing PVDS with the Landslide Complex;
and
WHEREAS, the City Council has, since that date and at various City Council
meetings, duly adopted resolutions prohibiting for specified periods set forth
therein, unicycles, bicycles, motorcycles, and other one- or two-wheeled vehicles
from traversing PVDS with the Landslide Complex; and
WHEREAS, staff and the Office of the City attorney are of the opinion that
conditions on PVDS have not stabilized to the point that this prohibition should be
allowed to terminate and is of the further opinion the existing prohibition should be
extended for an additional sixty (60) day period.
NOW, THEREFORE THE CITY COUNCIL OF THE CITY OF RANCHO
PALOS VERDES DOES HEREBY FIND, DETERMINE AND RESOLVE AS
FOLLOWS:
Section 1: The above recitals are true and correct and incorporated herein
by reference.
Section 2: For a period of sixty (60) calendar days from and after the date
of this resolution, the portion of PVDS within the Landslide Complex shall be closed
to unicycle, bicycle, motorcycle, and other one- or two-wheeled vehicle traffic.
Section 3: Updates on the rate of movement and repair of PVDS will be
provided at City Council meetings where the City Council is considering extending
the local state of emergency, including an assessment of the relative safety of
traveling on PVDS by unicycles, bicycles, motorcycles, and other one- or two-
wheeled vehicles through the Landslide Complex, with the purpose of lifting the
prohibition as soon as possible.
Section 4: This Resolution shall be effective immediately upon adoption by

01203.0001/835260.1 4
subcontractor's compliance with Division 2, Part 7, Chapter 1 (commencing with Section 1720)
of the California Labor Code, and shall make such compliance a requirement in any contract
with any subcontractor for work under this Agreement. Consultant shall be required to take all
actions necessary to enforce such contractual provisions and ensure subcontractor's compliance,
including without limitation, conducting a review of the certified payroll records of the
subcontractor on a periodic basis or upon becoming aware of the failure of the subcontractor to
pay his or her workers the specified prevailing rate of wages. Consultant shall diligently take
corrective action to halt or rectify any such failure by any subcontractor.

By executing this Agreement, Consultant warrants that Consultant (i) has thoroughly
investigated and considered the scope of services to be performed, (ii) has carefully considered
how the services should be performed, and (iii) fully understands the facilities, difficulties and
restrictions attending performance of the services under this Agreement. If the services involve
work upon any site, Consultant warrants that Consultant has or will investigate the site and is or
will be fully acquainted with the conditions there existing, prior to commencement of services
hereunder. Should the Consultant discover any latent or unknown conditions, which will
materially affect the performance of the services hereunder, Consultant shall immediately inform
the City of such fact and shall not proceed except at Consultant’s risk until written instructions
are received from the Contract Officer in the form of a Change Order.
1.7 Care of Work.
The Consultant shall adopt reasonable methods during the life of the Agreement to
furnish continuous protection to the work, and the equipment, materials, papers, documents,
plans, studies and/or other components thereof to prevent losses or damages, and shall be
responsible for all such damages, to persons or property, until acceptance of the work by City,
except such losses or damages as may be caused by City’s own negligence.
1.8 Further Responsibilities of Parties.
Both parties agree to use reasonable care and diligence to perform their respective
obligations under this Agreement. Both parties agree to act in good faith to execute all
instruments, prepare all documents and take all actions as may be reasonably necessary to carry
F-5
01203.0001/835260.1 5
out the purposes of this Agreement. Unless hereafter specified, neither party shall be responsible
for the service of the other.
1.9 Additional Services
City shall have the right at any time during the performance of the services, without
invalidating this Agreement, to order extra work beyond that specified in the Scope of Services
or make changes by altering, adding to or deducting from said work. No such extra work may be
undertaken unless a written Change Order is first given by the Contract Officer to the Consultant,
incorporating therein any adjustment in (i) the Contract Sum for the actual costs of the extra
work, and/or (ii) the time to perform this Agreement, which said adjustments are subject to the
written approval of the Consultant.
Any increase in compensation of up to 15% (fifteen percent) of the Contract Sum; or, in
the time to perform of up to 90 (ninety) days, may be approved by the Contract Officer through a
written Change Order. Any greater increases, taken either separately or cumulatively, must be
approved by the City Council. It is expressly understood by Consultant that the provisions of this
Section shall not apply to services specifically set forth in the Scope of Services. Consultant
hereby acknowledges that it accepts the risk that the services to be provided pursuant to the
Scope of Services may be more costly or time consuming than Consultant anticipates and that
Consultant shall not be entitled to additional compensation therefor. City may in its sole and
absolute discretion have similar work done by other Consultants. No claims for an increase in the
Contract Sum or time for performance shall be valid unless the procedures established in this
Section are followed.
If in the performance of the Services, the Contractor becomes aware of material defects
in the Scope of Work, duration, or span of the Services, or the Contractor becomes aware of
extenuating circumstance that will or could prevent the completion of the Services, on time or on
budget, the Contractor shall inform the City’s Contract Officer of an anticipated Change Order.
This proposed change order will stipulate the facts surrounding the issue, proposed solutions,
proposed costs, and proposed schedule impacts.

contractor contracts. Sub-contractor charges shall also be detailed by such categories. Consultant
shall not invoice City for any duplicate services performed by more than one person.
City shall independently review each invoice submitted by the Consultant to determine
whether the work performed and expenses incurred are in compliance with the provisions of this
Agreement. Except as to any charges for work performed or expenses incurred by Consultant
which are disputed by City, or as provided in Section 7.3, City will use its best efforts to cause
Consultant to be paid within 45 (forty-five) days of receipt of Consultant’s correct and
undisputed invoice; however, Consultant acknowledges and agrees that due to City warrant run
procedures, the City cannot guarantee that payment will occur within this time period. In the
event any charges or expenses are disputed by City, the original invoice shall be returned by City
F-7
01203.0001/835260.1 7
to Consultant for correction and resubmission. Review and payment by City for any invoice
provided by the Consultant shall not constitute a waiver of any rights or remedies provided
herein or any applicable law.
2.5 Waiver.

deemed to waive any defects in work performed by Consultant.

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

City nor does it waive any rights hereunder.

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

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

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.
(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 90 (ninety) 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

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

of said claims or liabilities and will pay all costs and expenses, including legal costs and
attorneys’ fees incurred in connection therewith;

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

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
F-16
01203.0001/835260.1 16
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 15 (fifteen) 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.
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.
F-17
01203.0001/835260.1 17
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 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. 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. 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 of termination without cause pursuant to this Section, the City need not provide the
Consultant with the opportunity to cure pursuant to Section 7.2.
7.8 Termination for Default of Party.
If termination is due to the failure of the other Party to fulfill its obligations under this
Agreement:
(a) 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.
(b) Consultant may, after compliance with the provisions of Section 7.2, terminate the
Agreement upon written notice to the City‘s Contract Officer. Consultant shall be entitled to
payment for all work performed up to the date of termination.

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.

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

b) Approach to Scope of Services
The following approach outlines our detailed methodology for delivering the City’s required scope of services in a clear, phased,
and efficient manner. Our team’s strategy emphasizes technical rigor, proactive coordination, federal funding compliance, and
constructible, resilient solutions that directly support the City’s goal of achieving long-term landslide stabilization.
1. Studies, Investigations, Computer Models, and Reports: GLA will build on prior studies by refining the existing
geotechnical model using updated field investigations, groundwater monitoring data, and slope movement records. We will
perform targeted investigations to evaluate the current groundwater regime, identify remaining data gaps, and calibrate
slope stability models using finite element or limit-equilibrium methods. Our approach prioritizes addressing the root cause of
instability through refined groundwater characterization and design-driven geotechnical modeling.
2. Construction Drawings, Specifications, and Documents: Our engineering team will develop a complete, constructible,
and agency-compliant set of plans and specifications. We will incorporate utility conflict avoidance, erosion control, traffic
management, and logistical phasing strategies. All drawings will be prepared and stamped by California-licensed engineers
and surveyors, reviewed by our internal QA/QC team, and delivered in both PDF and native formats. Plans will be developed in
progressive milestones (60%, 90%, Final) to enable iterative review and refinement.
3. Cost Estimate: A detailed, itemized cost estimate will be prepared in line with current market rates and recent bid data for
similar projects and it will include contingencies, soft costs, and unit pricing broken down by bid item and construction phase;
submit to City staff for review and approval.
4. Schedule Management: GLA will develop detailed project schedule at start of project using critical path method; regularly
update schedule, assess risks, and develop mitigation strategies for any delays. GLA will utilize MS Project software (or similar).
5. City Council Staff Report and Presentation: We will prepare a clear and visually supported presentation for City Council,
along with a staff report that aligns with City formatting and content standards. We will rehearse presentation materials with
City staff to ensure alignment with community messaging and project goals.
6. Environmental Compliance Documents: GLA and our subconsultant LSA will prepare all documentation required to
support third-party NEPA and historic preservation reviews in accordance with federal funding guidelines and will coordinate
closely with the City and funding agencies to ensure all requirements are fully addressed.
7. Utility and Agency Coordination: GLA and our subconsultant VELA Engineering, will review construction plans and
specifications, identify potential utility conflicts, coordinate with utility companies, and prepare and submit relocation or
adjustment documents as necessary.
8. Property Acquisitions and Easements: GLA and our subconsultant Epic Land Solutions, will complete a review of final
plans and specifications to assess whether proposed improvements may extend onto adjacent properties/public rights-of-
way, and if property acquisition or easements are required; we will delineate such needs graphically. We will coordinate with
City, legal advisors, and property owners (if applicable) to understand legal implications of acquiring property or easements
and whether existing easements can be leveraged. A boundary survey in support of easement acquisitions if necessary and
create legal descriptions and exhibits for said acquisitions.
9. Permitting: GLA will develop a comprehensive permitting matrix identifying agency requirements and timelines. We will
identify, prepare and submit needed permit applications to local/state/federal agencies.
10. Construction Procurement: Our team will prepare the Notice Inviting Bids using finalized construction drawings, bid
documents, the City’s standard forms, and contract templates. We will conduct a pre-bid conference, respond to Requests
for Information, participate in the bid opening, and evaluate bids for responsiveness, completeness, project understanding,
and bid amount. A memo documenting the award recommendation will be prepared, and upon review and concurrence by
City staff, GLA will draft the City Council Staff Report. Additionally, we will prepare and present recommendations to the City
Council for awarding the construction contract.
11. Administration and Coordination: We will maintain weekly progress meetings and repare status updates to City staff,
including activity summaries, budget tracking, and schedule or other agreed upon time interval performance to ensure
transparency, responsiveness, and the ability to resolve issues in real time.

d) Staff Qualifications and Experience
BRIEF FIRM HISTORY AND PRIOR EXPERIENCE
GLA is an employee-owned multi-disciplinary
civil, environmental, geologic, and geotechnical
consulting firm established in 1991. GLA employs
over 350 professionals located throughout 29 U.S.
office locations as well as an office in Lima, Peru.
To meet the City’s goals for landslide stabilization,
Geo-Logic Associates (GLA) has assembled a
multidisciplinary team of engineers, geologists, and
environmental specialists with direct experience
in geotechnical investigations, groundwater and
surface water interaction, slope stabilization design,
and federally funded infrastructure projects. Our
staff have successfully delivered projects involving
landslide mitigation, dewatering system design, slope
modeling, drainage and utility design, environmental
documentation, and construction support for public
agencies across California.
Our team’s qualifications include extensive experience with slope stability analysis, hydrologic and hydraulic modeling, drainage
and erosion control design, permit and utility coordination, and preparation of construction-ready plans and specifications.
We routinely manage projects from investigation through design and construction, ensuring integration across disciplines and
delivering solutions that are practical, cost-effective, and resilient to changing site conditions and climate extremes.
Our staff also have extensive experience in the planning, computer modeling, design, and construction phases of open and
closed conduit drainage channels, grading and drainage improvements, sediment control and transport, open and closed
channel hydraulics and hydrology, site paving and roadway plans, and public and private utilities.
GLA has provided the City with professional hydrogeologic and geotechnical consulting services for the Landslide Complex
since 2017, and developed preliminary mitigation plans, and technical specifications for its mitigation. In 2018, GLA was selected
to complete a feasibility study (FS) for the City and completed a watershed model in 2019. The FS was widely circulated, and
internally and externally peer reviewed. It showed that:
• The basal failure surface(s) that formed over an extended period of time is an effective hydraulic barrier;
• The predominant cause of landsliding within the Landslide Complex is artesian pressure that acts on the basal failure surface
throughout the geometry of the slide;
• One of the main contributors to the development of artesian pressure is surface water infiltration from canyons and ravines
that are at higher elevations;
• Seepage within the Landslide Complex sliding mass caused by infiltration of surface water through onsite cracks, onsite
ravines, and infiltration caused by irrigation, and through influx from leaky septic systems, are secondary sources of instability;
• The Landslide Complex is broken into multiple blocks, with relative movements affected; and
• The 2019 watershed model identified critical areas where stormwater was ponding and infiltrating into the landslide area.
Following the acceptance of the FS and watershed model in 2019, GLA completed the preliminary mitigation design which
called for:
(i) management of groundwater that is the source of artesian pressure;
(ii) relief of residual artesian pressure at the toe of the slide; within the entire Landslide Complex; and
(iii) infilling of cracks and improvement of surface drainage to minimize seepage into the landslide mass.
The first two items will be addressed by installation of deep dewatering wells and horizontal/directional drains, where
appropriate, generally outside of the landslide footprint and below the basal failure surface (so they do not get sheared off as
the slide moves).

In 2023, GLA was selected to provide the final Landslide Mitigation, Exploration, Dewatering and Winterization Design. Work
on this project includes siting deep exploratory boreholes, daily slope monitoring and strategic planning for more permanent
stabilization techniques. In the process, GLA has developed a keen awareness of the City’s and local needs, as well as state and
local standards and procedures. Our recent work has further refined the complex nature of the landslide complex, especially
in the PBL where a deeper landslide was discovered that had never historically failed before. This success is founded on the
principles of ensuring that our work is conducted to a high professional standard, our work product is technically defensible,
our clients’ best interests inform our decisions, and our services are provided cost effectively. The long-term working
relationships we have with our clients is a testament to the effectiveness of this approach. GLA staff have a history of providing
hydrogeological and hydraulic services to the City , and as a result, we have an unparalleled familiarity with site geologic and
hydrogeologic conditions.
The City and others have largely characterized the geologic, hydrologic, hydrogeologic, and geotechnical conditions that drive
regional slope failure and have implemented some preliminary mitigation measures. However, now the City is undertaking a
focused effort to meet the following objectives:
• Long-term stabilization of the landslide complex
• Repair and upgrade related infrastructure
• Compliance with applicable federal, state, and local environmental laws and regulations
GLA will work closely with the City to utilize the results of the numerous prior and ongoing geologic studies and engineering
evaluations. This project will provide a comprehensive and coordinated approach to controlling stormwater runoff and
mitigating infiltration at the source. Portions of our civil design, especially surface water management and drainage
improvements will rely on the final results of the hydrologic/hydraulic study that is being commissioned by the City
with Geosyntec*.
Our team will utilize industry-leading tools and expertise to deliver high-quality plans that meet regulatory standards and
support the City’s sustainability goals. We look forward to working with the City to implement this critical program.

Feasibility Study and Hydrologic Model
Daniel B. Stephens and Associates, Inc. (DBS&A), a subsidiary of Geo-Logic
Associates, Inc., assisted city staff in their preparation for an anticipated
federal infrastructure plan expected in 2017 to provide funds for landslide
abatement. Part of this effort was to review and update an existing
engineering feasibility study (FS) prepared by the U.S. Army Corps of
Engineers (USACE) in 2000. The USACE FS only proposed a coastal dike in
an effort to stabilize coastal erosion, however, the landslide itself was not
directly addressed.
DBS&A commenced a thorough compilation and review of all available
historical work on the Portuguese Bend landslide, adjacent area landslides
including Abalone Cove, Klondike Canyon, and the larger Altamira
Complex. This review resulted in the compilation of nearly 100 GB of
historical files in electronic format that had not been organized before. In
addition, DBS&A completed a systematic and through review of the
historical data, reports, studies, engineering work, and research along
with available public scientific literature to characterize the landslide
geology, hydrogeology, groundwater occurrence, recharge, past
mitigation efforts, and past successes and failures.
The comprehensive review formed the basis of an updated hydrogeologic
conceptual site model that was used to prepare a new engineering feasibility
study in 2018 to evaluate and present available options for landslide
abatement including groundwater extraction wells, horizontal drains
(hydraugers), and stormwater control. A watershed model was prepared to
quantify groundwater recharge components including rainfall and irrigation.
Areas of critical stormwater ponding and infiltration were identified. The FS
included geotechnical modeling and conceptual-level cost estimates for
groundwater extraction wells, hydraugers, fracture-sealing, stormwater control, and a partial centralized
sanitary sewer to replace some septic systems in the area. DBSA directed and participated in several
city council meetings to present the draft FS options, receive public stakeholder comments, and
incorporate the comments into a final FS report. The final FS outlined the primary components of
subsequent work elements completed by the City from 2019 to present.

Portuguese Bend Landslide
Rancho Palos Verdes, California

`
The Portuguese Bend Landslide (PBL), located along the Pacific Coast in the
City of Rancho Palos Verdes (City), is among the most recognizable
landslide features in California and the fastest-moving landslide in the
United States. This massive landslide encompasses approximately 239
acres and 38 million cubic yards, with lateral dimensions of approximately
0.9 miles by 0.8 miles. Ground movement rates vary widely across the site
but have been recently measured to be as much as 11 feet per year near
the landslide’s toe at the coast.
In 2018, GLA prepared a feasibility study for the City’s use in developing
and comparing options to mitigate the ongoing landslide movement.
Subsequently, the City commissioned GLA to develop a mitigation design
to the permit level. Key components of GLA’s mitigation design included
innovative engineering approaches for surface water control using
geosynthetic-lined swales and for artesian groundwater pressure relief
using directionally installed drains.
To design surface water management features, GLA performed a
hydrologic analysis to calculate the estimated design flows for a 100-year,
24-hour design storm event using the methodology outlined in the Los
Angeles County Department of Public Works Hydrology Manual. The
hydrologic parameters were then applied in hydraulic calculations to design
the proposed engineered swales, culvert pipes, and a flow reduction area
included in the mitigation design package.
GLA also supported the City in characterizing new, larger landslide
movement and developing emergency mitigation measures to reduce land
movement and addressing the concerns of residents, the City Council, and
the Palos Verdes Peninsula Land Conservancy. GLA delivered three project
briefings to the public on the City’s behalf, and GLA’s original design report
was accepted by a unanimous vote of the City Council.

When GLA starts a new project, we identify the reviewer(s) for each task and assign a senior professional to do coordination
review. Overall quality assurance for this contract will be the responsibility of the Project Manager, William McCormick, CEG.
GLA will prepare all technical documents and plans with review and approval by appropriately licensed professionals, and
engineering drawings and specifications will be sealed by a California registered professional engineer. We will conduct
routine quality control reviews to verify that all project deliverables and supporting documents are complete, understandable,
conform to standards, and meet City’s expectations.
GLA maintains a reputation for preparing high-quality technical reports. A careful process of document production maintains
our high standard. This process includes reviews for technical accuracy by a technical manager familiar with the project goals
and objectives; a complete editorial review that ensures logical sequence of ideas and clear, concise writing; and a final quality
assurance check by the project manager prior to submission to a client.
Our team knows the importance of providing high-quality final deliverables that thoroughly address all applicable
requirements. Report and plan preparation typically involves development of a draft (or 60%, 90%, and 100% submittal for
plans) for client review and comment, and completion of a final draft with client input and approval. All GLA deliverables are
reviewed in accordance with GLA’s Quality Assurance Manual (QAM) to ensure a high-quality end product. GLA employs a full-
time production team responsible for conducting final editorial reviews and production of all documents. This ensures quality,
accuracy, compliance, and completeness of reports prepared by GLA. Reports are delivered according to need or preference in
hard-copy and/or electronic format.
GLA has an accounting team that assists with contract review, invoice production, review, and submittal. Our contract specialists
review all contract requirements and consistently follow specific invoicing procedures in our Deltek Vision accounting system
when each project is opened, ensuring consistency and accuracy on all of our invoices. Utilizing this system, we are able to
produce draft and final invoices that include all back-up documentation as required. Draft invoices are provided to the PM for
review and approval. Once approved, invoices are submitted to the correct financial contact and to the PM as requested.
Monitoring Quality of Subcontractor Work
Project teams that include multiple subcontractors add value to projects by enabling personnel from specialized backgrounds
and varying disciplines to work together to produce the best solution. However, multiple team members also means added
complexity and increased need for oversight. GLA understands our role and, as the prime, we will ensure that our subcontractors
provide the same level of quality that we expect from our staff. To ensure that the quality of subcontractor work is carefully
monitored, GLA adheres to the following oversight procedures:
• Regular communication with all subcontractors
• Quality assurance and data review/audit of work performed by subcontractors
• All reports and documentation prepared by subcontractors are subject to GLA’s internal review and production process prior
to submission to the client
g) Accepance of Conditions
GLA has reviewed the sample professional services agreement and is proposing that the City consider incorporating the
following revisions to the contract.

b) Approach to Scope of Services
The following approach outlines our detailed methodology for delivering the City’s required scope of services in a clear, phased,
and efficient manner. Our team’s strategy emphasizes technical rigor, proactive coordination, federal funding compliance, and
constructible, resilient solutions that directly support the City’s goal of achieving long-term landslide stabilization.
1. Studies, Investigations, Computer Models, and Reports: GLA will build on prior studies by refining the existing
geotechnical model using updated field investigations, groundwater monitoring data, and slope movement records. We will
perform targeted investigations to evaluate the current groundwater regime, identify remaining data gaps, and calibrate
slope stability models using finite element or limit-equilibrium methods. Our approach prioritizes addressing the root cause of
instability through refined groundwater characterization and design-driven geotechnical modeling.
2. Construction Drawings, Specifications, and Documents: Our engineering team will develop a complete, constructible,
and agency-compliant set of plans and specifications. We will incorporate utility conflict avoidance, erosion control, traffic
management, and logistical phasing strategies. All drawings will be prepared and stamped by California-licensed engineers
and surveyors, reviewed by our internal QA/QC team, and delivered in both PDF and native formats. Plans will be developed in
progressive milestones (60%, 90%, Final) to enable iterative review and refinement.
3. Cost Estimate: A detailed, itemized cost estimate will be prepared in line with current market rates and recent bid data for
similar projects and it will include contingencies, soft costs, and unit pricing broken down by bid item and construction phase;
submit to City staff for review and approval.
4. Schedule Management: GLA will develop detailed project schedule at start of project using critical path method; regularly
update schedule, assess risks, and develop mitigation strategies for any delays. GLA will utilize MS Project software (or similar).
5. City Council Staff Report and Presentation: We will prepare a clear and visually supported presentation for City Council,
along with a staff report that aligns with City formatting and content standards. We will rehearse presentation materials with
City staff to ensure alignment with community messaging and project goals.
6. Environmental Compliance Documents: GLA and our subconsultant LSA will prepare all documentation required to
support third-party NEPA and historic preservation reviews in accordance with federal funding guidelines and will coordinate
closely with the City and funding agencies to ensure all requirements are fully addressed.
7. Utility and Agency Coordination: GLA and our subconsultant VELA Engineering, will review construction plans and
specifications, identify potential utility conflicts, coordinate with utility companies, and prepare and submit relocation or
adjustment documents as necessary.
8. Property Acquisitions and Easements: GLA and our subconsultant Epic Land Solutions, will complete a review of final
plans and specifications to assess whether proposed improvements may extend onto adjacent properties/public rights-of-
way, and if property acquisition or easements are required; we will delineate such needs graphically. We will coordinate with
City, legal advisors, and property owners (if applicable) to understand legal implications of acquiring property or easements
and whether existing easements can be leveraged. A boundary survey in support of easement acquisitions if necessary and
create legal descriptions and exhibits for said acquisitions.
9. Permitting: GLA will develop a comprehensive permitting matrix identifying agency requirements and timelines. We will
identify, prepare and submit needed permit applications to local/state/federal agencies.
10. Construction Procurement: Our team will prepare the Notice Inviting Bids using finalized construction drawings, bid
documents, the City’s standard forms, and contract templates. We will conduct a pre-bid conference, respond to Requests
for Information, participate in the bid opening, and evaluate bids for responsiveness, completeness, project understanding,
and bid amount. A memo documenting the award recommendation will be prepared, and upon review and concurrence by
City staff, GLA will draft the City Council Staff Report. Additionally, we will prepare and present recommendations to the City
Council for awarding the construction contract.
11. Administration and Coordination: We will maintain weekly progress meetings and repare status updates to City staff,
including activity summaries, budget tracking, and schedule or other agreed upon time interval performance to ensure
transparency, responsiveness, and the ability to resolve issues in real time.

d) Staff Qualifications and Experience
BRIEF FIRM HISTORY AND PRIOR EXPERIENCE
GLA is an employee-owned multi-disciplinary
civil, environmental, geologic, and geotechnical
consulting firm established in 1991. GLA employs
over 350 professionals located throughout 29 U.S.
office locations as well as an office in Lima, Peru.
To meet the City’s goals for landslide stabilization,
Geo-Logic Associates (GLA) has assembled a
multidisciplinary team of engineers, geologists, and
environmental specialists with direct experience
in geotechnical investigations, groundwater and
surface water interaction, slope stabilization design,
and federally funded infrastructure projects. Our
staff have successfully delivered projects involving
landslide mitigation, dewatering system design, slope
modeling, drainage and utility design, environmental
documentation, and construction support for public
agencies across California.
Our team’s qualifications include extensive experience with slope stability analysis, hydrologic and hydraulic modeling, drainage
and erosion control design, permit and utility coordination, and preparation of construction-ready plans and specifications.
We routinely manage projects from investigation through design and construction, ensuring integration across disciplines and
delivering solutions that are practical, cost-effective, and resilient to changing site conditions and climate extremes.
Our staff also have extensive experience in the planning, computer modeling, design, and construction phases of open and
closed conduit drainage channels, grading and drainage improvements, sediment control and transport, open and closed
channel hydraulics and hydrology, site paving and roadway plans, and public and private utilities.
GLA has provided the City with professional hydrogeologic and geotechnical consulting services for the Landslide Complex
since 2017, and developed preliminary mitigation plans, and technical specifications for its mitigation. In 2018, GLA was selected
to complete a feasibility study (FS) for the City and completed a watershed model in 2019. The FS was widely circulated, and
internally and externally peer reviewed. It showed that:
• The basal failure surface(s) that formed over an extended period of time is an effective hydraulic barrier;
• The predominant cause of landsliding within the Landslide Complex is artesian pressure that acts on the basal failure surface
throughout the geometry of the slide;
• One of the main contributors to the development of artesian pressure is surface water infiltration from canyons and ravines
that are at higher elevations;
• Seepage within the Landslide Complex sliding mass caused by infiltration of surface water through onsite cracks, onsite
ravines, and infiltration caused by irrigation, and through influx from leaky septic systems, are secondary sources of instability;
• The Landslide Complex is broken into multiple blocks, with relative movements affected; and
• The 2019 watershed model identified critical areas where stormwater was ponding and infiltrating into the landslide area.
Following the acceptance of the FS and watershed model in 2019, GLA completed the preliminary mitigation design which
called for:
(i) management of groundwater that is the source of artesian pressure;
(ii) relief of residual artesian pressure at the toe of the slide; within the entire Landslide Complex; and
(iii) infilling of cracks and improvement of surface drainage to minimize seepage into the landslide mass.
The first two items will be addressed by installation of deep dewatering wells and horizontal/directional drains, where
appropriate, generally outside of the landslide footprint and below the basal failure surface (so they do not get sheared off as
the slide moves).

In 2023, GLA was selected to provide the final Landslide Mitigation, Exploration, Dewatering and Winterization Design. Work
on this project includes siting deep exploratory boreholes, daily slope monitoring and strategic planning for more permanent
stabilization techniques. In the process, GLA has developed a keen awareness of the City’s and local needs, as well as state and
local standards and procedures. Our recent work has further refined the complex nature of the landslide complex, especially
in the PBL where a deeper landslide was discovered that had never historically failed before. This success is founded on the
principles of ensuring that our work is conducted to a high professional standard, our work product is technically defensible,
our clients’ best interests inform our decisions, and our services are provided cost effectively. The long-term working
relationships we have with our clients is a testament to the effectiveness of this approach. GLA staff have a history of providing
hydrogeological and hydraulic services to the City , and as a result, we have an unparalleled familiarity with site geologic and
hydrogeologic conditions.
The City and others have largely characterized the geologic, hydrologic, hydrogeologic, and geotechnical conditions that drive
regional slope failure and have implemented some preliminary mitigation measures. However, now the City is undertaking a
focused effort to meet the following objectives:
• Long-term stabilization of the landslide complex
• Repair and upgrade related infrastructure
• Compliance with applicable federal, state, and local environmental laws and regulations
GLA will work closely with the City to utilize the results of the numerous prior and ongoing geologic studies and engineering
evaluations. This project will provide a comprehensive and coordinated approach to controlling stormwater runoff and
mitigating infiltration at the source. Portions of our civil design, especially surface water management and drainage
improvements will rely on the final results of the hydrologic/hydraulic study that is being commissioned by the City
with Geosyntec*.
Our team will utilize industry-leading tools and expertise to deliver high-quality plans that meet regulatory standards and
support the City’s sustainability goals. We look forward to working with the City to implement this critical program.

Feasibility Study and Hydrologic Model
Daniel B. Stephens and Associates, Inc. (DBS&A), a subsidiary of Geo-Logic
Associates, Inc., assisted city staff in their preparation for an anticipated
federal infrastructure plan expected in 2017 to provide funds for landslide
abatement. Part of this effort was to review and update an existing
engineering feasibility study (FS) prepared by the U.S. Army Corps of
Engineers (USACE) in 2000. The USACE FS only proposed a coastal dike in
an effort to stabilize coastal erosion, however, the landslide itself was not
directly addressed.
DBS&A commenced a thorough compilation and review of all available
historical work on the Portuguese Bend landslide, adjacent area landslides
including Abalone Cove, Klondike Canyon, and the larger Altamira
Complex. This review resulted in the compilation of nearly 100 GB of
historical files in electronic format that had not been organized before. In
addition, DBS&A completed a systematic and through review of the
historical data, reports, studies, engineering work, and research along
with available public scientific literature to characterize the landslide
geology, hydrogeology, groundwater occurrence, recharge, past
mitigation efforts, and past successes and failures.
The comprehensive review formed the basis of an updated hydrogeologic
conceptual site model that was used to prepare a new engineering feasibility
study in 2018 to evaluate and present available options for landslide
abatement including groundwater extraction wells, horizontal drains
(hydraugers), and stormwater control. A watershed model was prepared to
quantify groundwater recharge components including rainfall and irrigation.
Areas of critical stormwater ponding and infiltration were identified. The FS
included geotechnical modeling and conceptual-level cost estimates for
groundwater extraction wells, hydraugers, fracture-sealing, stormwater control, and a partial centralized
sanitary sewer to replace some septic systems in the area. DBSA directed and participated in several
city council meetings to present the draft FS options, receive public stakeholder comments, and
incorporate the comments into a final FS report. The final FS outlined the primary components of
subsequent work elements completed by the City from 2019 to present.

City of Rancho Palos Verdes (City), is among the most recognizable
landslide features in California and the fastest-moving landslide in the
United States. This massive landslide encompasses approximately 239
acres and 38 million cubic yards, with lateral dimensions of approximately
0.9 miles by 0.8 miles. Ground movement rates vary widely across the site
but have been recently measured to be as much as 11 feet per year near
the landslide’s toe at the coast.
In 2018, GLA prepared a feasibility study for the City’s use in developing
and comparing options to mitigate the ongoing landslide movement.
Subsequently, the City commissioned GLA to develop a mitigation design
to the permit level. Key components of GLA’s mitigation design included
innovative engineering approaches for surface water control using
geosynthetic-lined swales and for artesian groundwater pressure relief
using directionally installed drains.
To design surface water management features, GLA performed a
hydrologic analysis to calculate the estimated design flows for a 100-year,
24-hour design storm event using the methodology outlined in the Los
Angeles County Department of Public Works Hydrology Manual. The
hydrologic parameters were then applied in hydraulic calculations to design
the proposed engineered swales, culvert pipes, and a flow reduction area
included in the mitigation design package.
GLA also supported the City in characterizing new, larger landslide
movement and developing emergency mitigation measures to reduce land
movement and addressing the concerns of residents, the City Council, and
the Palos Verdes Peninsula Land Conservancy. GLA delivered three project
briefings to the public on the City’s behalf, and GLA’s original design report
was accepted by a unanimous vote of the City Council.

f) Quality Control Plan
When GLA starts a new project, we identify the reviewer(s) for each task and assign a senior professional to do coordination
review. Overall quality assurance for this contract will be the responsibility of the Project Manager, William McCormick, CEG.
GLA will prepare all technical documents and plans with review and approval by appropriately licensed professionals, and
engineering drawings and specifications will be sealed by a California registered professional engineer. We will conduct
routine quality control reviews to verify that all project deliverables and supporting documents are complete, understandable,
conform to standards, and meet City’s expectations.
GLA maintains a reputation for preparing high-quality technical reports. A careful process of document production maintains
our high standard. This process includes reviews for technical accuracy by a technical manager familiar with the project goals
and objectives; a complete editorial review that ensures logical sequence of ideas and clear, concise writing; and a final quality
assurance check by the project manager prior to submission to a client.
Our team knows the importance of providing high-quality final deliverables that thoroughly address all applicable
requirements. Report and plan preparation typically involves development of a draft (or 60%, 90%, and 100% submittal for
plans) for client review and comment, and completion of a final draft with client input and approval. All GLA deliverables are
reviewed in accordance with GLA’s Quality Assurance Manual (QAM) to ensure a high-quality end product. GLA employs a full-
time production team responsible for conducting final editorial reviews and production of all documents. This ensures quality,
accuracy, compliance, and completeness of reports prepared by GLA. Reports are delivered according to need or preference in
hard-copy and/or electronic format.
GLA has an accounting team that assists with contract review, invoice production, review, and submittal. Our contract specialists
review all contract requirements and consistently follow specific invoicing procedures in our Deltek Vision accounting system
when each project is opened, ensuring consistency and accuracy on all of our invoices. Utilizing this system, we are able to
produce draft and final invoices that include all back-up documentation as required. Draft invoices are provided to the PM for
review and approval. Once approved, invoices are submitted to the correct financial contact and to the PM as requested.
Monitoring Quality of Subcontractor Work
Project teams that include multiple subcontractors add value to projects by enabling personnel from specialized backgrounds
and varying disciplines to work together to produce the best solution. However, multiple team members also means added
complexity and increased need for oversight. GLA understands our role and, as the prime, we will ensure that our subcontractors
provide the same level of quality that we expect from our staff. To ensure that the quality of subcontractor work is carefully
monitored, GLA adheres to the following oversight procedures:
• Regular communication with all subcontractors
• Quality assurance and data review/audit of work performed by subcontractors
• All reports and documentation prepared by subcontractors are subject to GLA’s internal review and production process prior
to submission to the client
g) Accepance of Conditions
GLA has reviewed the sample professional services agreement and is proposing that the City consider incorporating the
following revisions to the contract.
6.3 Ownership of Documents.

I. INTRODUCTION
The City of Rancho Palos Verdes (City) 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 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.
The purpose of this document is to provide proposers with the information needed to
submit a proposal for review by the City and enter into a Professional Service Agreement
with the City. Enclosed is a blank Professional Services Agreement form for proposers’
review.
II. PROJECT OBJECTIVE
The object of the Portuguese Bend Landslide Remediation Project (Project) is to stabilize
the Portuguese Bend Landslide within the Greater Portuese Bend Landslide Complex by
reducing the rate of movement to a negligible amount.
III. PROJECT DESCRIPTION AND BACKGROUND
The City faces an escalating geohazard due to the reactivation and worsening of the
Portuguese Bend Landslide (PBL) – an ancient landslide area spanning 240 acres that
has remained unstable for decades. Efforts to remediate the PBL began in 2017 and
resulted in a 2018 Feasibility Study as well as a concept plan used to prepare a Draft
Environmental Impact Report (DEIR) in 2023. However, subsequent consecutive years
of record rainfall significantly intensified land movement. Portions of the slope have
recently moved up to one foot per week and are now shifting 1–3 inches per week. The
increasing velocity threatens critical infrastructure and regional public safety.
Completion of the PBL Remediation Project requires modifying the scope of the concept
plan and completing final engineering as well as associated items such as permits and
environmental documents. The overall concept is not expected to change; however, the
type, number, and location of dewatering wells must be updated.

The Portuguese Bend Landslide creates a number of challenges for the City and the
community including damage to Palos Verdes Drive South, utilities, and public and private
properties. The completion of this project will help minimize movement in the Portuguese
Bend Landslide, thereby minimizing potential impacts to the surrounding environment
including marine life in the event the existing above-ground sewer lines are damaged. It will
also minimize damage to public and private properties, including the roadway, and will
alleviate the need for the annual Palos Verdes Drive South Landslide Repair Program.
