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 July 5, 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 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
5
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 with two monitoring wells and instrumentation
that would be installed, maintained and operated by ACLAD within their jurisdictional
boundaries. A $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 June 20, 2025, only 6.58 inches of rain has fallen at the Rolling Hills Fire Station 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 2024-25 rainy season continues to be
insignificant in terms of landslide movement, which generally continues to decelerate or
maintain an overall steady state in areas that are still moving. This is believed to be largely
due to significantly below-average rainfall through mid-June, positive effects from the
major winterization efforts undertaken by the City and the landslide abatement districts in
the fall and early winter, and ongoing dewatering efforts by the City and abatemen t
districts.
Recent GPS survey data published by McGee Surveying Consulting for the approximately
“monthly” monitoring periods of May 2, 2025 and June 3, 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 May 2, 2025 and
June 3, 2025 full monitoring periods. (Attachment D)

For all points monitored across the entire Landslide Complex, following are the key
conclusions for the time period of April 5 through June 3, 2025:
• The ACL, within its historical boundary, has decelerated an average of
approximately 14% between April 5, 2025 and June 3, 2025. The average rate of
movement for these points was 1.31 ft/month from May 2 to June 3, 2025. The
ACL movement has decelerated 60% since the deep dewatering program
commenced in mid-September 2024. The fastest moving area is now the upper
portion of the ACL at an average of 1.5 feet per month (about 4 inches per week);
however, the area of the ACL moving at this rate continues to shrink, most likely in
response to recent deep dewatering efforts by ACLAD. It is anticipated that this
movement rate will continue to decelerate as additional wells come online and
dewatering production increases.
• The PBL, within its historical boundary, has decelerated an average of 11% from
April 5, 2025 through June 3, 2025. The average rate of movement for these points
was 0.77 ft/month from May 2 2025 to June 3, 2025. The PBL movement has
decelerated 78% since the deep dewatering program commenced in mid -
September 2024. The PBL was previously viewed as having reached a steady
state of movement since the end of October 2024; however it continues to
decelerate.
• 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 13% from April 5, 2025 through June 3, 2025. The
average rate of movement for these points was 1.17 ft/month from May 2-June 3,
2025. The Greater Portuguese Bend/Ancient Altamira Landslide Complex points
have decelerated 63% 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 -
2024) 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
8
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, and in the Seaview Tract.

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.
Figure 3: Deep Dewatering Wells
Following are key notes regarding specific DDWs:
• The total combined water extraction rate of the DDWs is currently approximately 790
gallons per minute or 1.14 million gallons per day.
• Since the start of the DDW program, approximately 263 million gallons, or 806 acre-
feet of water have been extracted.
• DDWs 9A, 10, 6, and 2 were re-drilled over the last 2 months leading to increases in
overall extraction rates.
• DDW-7 recently sheared and based on the low production rate of this DDWs, the
City’s Geologists are advising that the well not be re -drilled, but rather re-located,
should additional funding become available.
• 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.

Water Pressure Measurements
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.
continued on next page
11
Figure 4: Water Pressure Measurement Instrument Locations
Figure 5 shows water pressures from the piezometers installed under the deep slip plane
and Figure 6 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.
continued on next page
12
Figure 5: Deep Slip Plane Water Pressure Chart
Figure 6: Mid-Deep Slip Plane Water Pressure Chart
For those piezometers near the DDWs (P-1, P-2, and P-3), the plots show a marked
decrease in pressure immediately following the start of the DDW program . The surviving
piezometer, P-2, continues to show a marked pressure drop over time, which correlates
to reduced surface movement in nearby GPS survey points.
The piezometers far away from DDWs (E-2-2 and E-2-5) show only a slight to almost no
decrease in pressure over time. The slight reduction shown in piezometer E -2-5 is likely
the result of drying conditions and below normal rainfall.
13
It is notable that the drop in pressure for piezometer P-2 where there is water pumping is
almost twice the drop in pressure for piezometer E-2-5 where there is no water pumping.
Emergency Winterization Status
Winterization activities for the 2024-25 rainy season are complete. Preparations for the
2025-26 rainy season will begin in the coming weeks.
ACLAD Update
Following is the status of ACLAD’s activities as of June 20, 2025:
• 6 original/shallow wells are operational and extracting water at a rate of
approximately 65 gallons per minute.
• 9 DDWs are operational and extracting water at a rate of approximately 35 gallons
per minute.
• Drain wells do not operate during the evening hours due to the use of generators.
• Drain line connections for an additional 2 DDWs are in progress.
• 2 Monitoring Wells with piezometers have been installed.
• Various repairs and drainage line improvements are being planned
Exhibit 2: KCALD Dewatering Wells
City Staff, along with the City’s consultant engineering geologists are regularly
coordinating with ACLAD and beginning to collect and analyze data from the piezometers
in the monitoring wells. Additionally, the City has revised the partial (mid-month) GPS
14
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.
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.
KCLAD Update
Following is the status of KCLAD’s activities as of June 18, 2025:
• KCLAD Well 6 has been shut off because of very little groundwater in the area.
• KCLAD Well 5 is extracting water at a rate of approximately 80 gallons per minutes
and is showing a water level of approximately 93 feet below ground surface.
• An additional DDW is being considered along with repairs to two shallow wells
(KCLAD 3 and KCLAD 4).
• Weekly readings are uploaded to the KCLAD website (KCGHAD.org).

detailed system integrity assessment of
underground infrastructure to determine
how to safely restore gas.
April Seaview & PBBC Steel pipelines in PBBC and Seaview
showed a higher-than-expected resilience
to subsurface movement and stress,
resulting in positive potential of restoration.
May & June Seaview SoCalGas began work on restoring
service in Seaview. Restoration of service
includes modernizing portions of the
existing infrastructure, adding safety
mitigation such as automatic shut-off
valves, additional manual valves, and real-
time pressure monitoring equipment. The
work is continuing generally according to
plan with the exception that some
additional segments of pipe are being
replaced. Restoration of service to
Seaview is expected in Q3 with restoration
in PBBC to follow.
All restoration plans are dependent upon sustained minimal land movement rates, which
will continue to be monitored by SoCalGas and local partners. The City will continue
working with CPUC and SoCalGas to advocate for restoring gas service to the PBCA in
a manner that aligns with public safety and community needs.

for 1-3 weeks, leaving 30 properties without
electricity.
Q4 Re-energized 16 customers located
primarily on Fruit Tree Road, Plumtree
Road, and Narcissa Drive in the western
portion of the Landslide Complex.
2025
January 13 Seaview & PBBC Plan proposed to temporarily restore
power to up to 116 customers, including
approximately 76 properties by
approximately the end of Q1 (March 31,
2025), excluding red-tagged homes.
February - June Seaview & PBBC 74 homes and 2 KCLAD dewatering well
meters re-energized.
16 homes in the PBBC and Seaview
communities remain without power,
awaiting electrical inspection clearance.
SCE will re-energize the remaining homes
on a weekly basis upon successful
completion of electrical inspection.

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.
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
in PBCA and declining to bear the cost of undergrounding their relocation. City Staff will
be requesting guidance on the options from City Council at the July 15, 2025 Council
meeting.
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.
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.
As a separate agenda item this evening, the City Council will be asked to consider an
adjustment to the rate paid by users, which the City Council considers annually.
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
the sewer system in areas affected by the landslide and performing repairs when needed.
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 (LA CSD) 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.
18
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 preventing
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 expected to be complete by the end of July 2025.
Water (California Water Service – Cal Water)

Financial Update
Expenditures to Date and FY 2024-25 Year-End Estimates
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.
20
As shown in Table 3a and Chart 1 on the following page, year-to-date expenditures and
encumbrances have increased from $32.31 million in the May 6, 2025 report to $33.12
million. This reflects a rise of $810,000, or 3%, since the last report to the City Council.
The remaining $3.68 million is projected to be used once final billings for services through
June 30, 2025, are received, bringing the total projected expenditures for FY 2024–25 to
$36.81 million.
Overall, compared to FY 2023-24, the projected $36.81 million 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 until June
30, 2025, 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. At this time, there are no
expenditures to report since the budget takes effect on July 1, 2025. The next update,
scheduled for August 19, 2025, will include a status report along with the City Council’s
direction to present a priority rank list of landslide emergency response projects and
activities totaling $9 million. The City Council may then begin to consider future budget
reductions based on the priority order rank list.
ACLAD/KCLAD Loans
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.
FY 2024-25 Expenditure Report for ACLAD and KCLAD (ending April 2025)
Staff continues to work with both Districts to obtain the most current financial reports for
ACLAD and KCLAD. Based on the most recently available financial information, Table 4
22
below presents the total expenditures for ACLAD and KCLAD, respectively, through April
2025.
As of the end of April 2025, ACLAD’s total expenditure is almost $1.8 million, which is
over budget by $1.2 million (202%). This overage is being funded through a combination
of the District’s reserves and a portion of the loan provided by the City. The primary
expenditure category is operations and maintenance for the wells, totaling $1 .7 million,
compared to the original budget of $480,000. Of this amount, approximately $1.3 million
are for the new drilling costs.
Table 4a: ACLAD Expenditure Report (July 1, 2024 – April 2025)
ACLAD Budget Actuals Variance ($) Variance (%)
Administration $21,150 $22,923 -$1,773 -8%

Reserves/Contingency $29,850
TOTAL $598,000 $1,777,662 -$1,209,512 -202%
For KCLAD, total expenditure is $1.2 million, which is over budget by $691,000 (121%).
This overage is being funded through a combination of the District’s reserves and a
portion of the loan provided by the City. The primary expenditure category is operations
and maintenance for the wells, totaling $1 million, compared to the original budget of
$290,000.

Reserves/Contingency $51,870
TOTAL $570,570 $1,209,824 -$691,124 -121%
Tax Assessments
Based on the District’s adopted tax allocation formula, the City’s share to the annual
budget, as a landowner, is approximately 60%. As part of the FY 2025-26 Adopted
Budget, total tax assessments are estimated at $860,300, which is an increase of
$144,853 (20%) compared to FY 2024-25 (Table 5). Compared to FY 2021-22, the FY
2025-26 tax assessments increased by $699,654 (435%).
The primary increases in FY 2025-26 are higher maintenance-related costs, including
increased expenses for maintenance services and parts , well drilling costs, and utility
expenses. These cost increases are largely attributed to ongoing response and
stabilization efforts related to the landslide areas within ACLAD and KCLAD.

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 conducting field mapping throughout the Landslide Complex; observing
conditions at various locations, reviewing survey and rainfall data; and participating in
various discussions with stakeholders. While the City’s geologist reports the rate of
subsidence and land movement has slowed, pavement conditions on PVDS remain very
poor, with cracks, bumps, fissures, and other irregularities. Moreover, recent roadway
experience indicates the roadbed of PVDS shows evidence of emerging cracks, bumps,
fissures, and potholes sometimes forming almost overnight. The rate of movement on
PVDS is up to four inches per week in certain areas.
Although four-wheeled vehicles (i.e. cars) can, with due care, navigate the road under
these conditions, 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 permi tting 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 of 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 July 5, 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 August 30, 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 August 19, 2025. The City Council
is being asked to adopt the attached resolution thereby extending the Declaration of Local
Emergency by 60 days (Attachment B).
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 un til 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 July 5, 2025,

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 July 15, 2025 City Council meeting. Additionally, Staff will provid e other relevant
information for the City Council’s consideration such as legal requirements and Coastal
Commission jurisdiction.
Abatement of 4362 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, Rancho Palos Verdes, CA
90275 (Assessor’s Parcel Number 75664-004-026). 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 demolition activities are anticipated to be conducted as early as the end of June 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.
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.
Disaster Cost Recovery Applications Update (FEMA and CalOES)
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
26
September 12, 2024 for reimbursement consideration by FEMA and CalOES. Table 6
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).
Table 6: Cost Recovery Applications

In Millions
FEMA Public Assistance (City) Winter Storm (Jan/Feb 24) 38.4

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.
On January 17, 2025, of the $38.4 million applied for public assistance related to the
winter storm, summarized and shown in Table 7, 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. (Attachment I)
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 Hazard Mitigation Grant Program (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 23
properties (13 red-tagged, and 10 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.
29
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 23 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.
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 plans to apply in the near future for additio nal
HMGP funding in order to potentially offer more rounds of the buyout program.
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 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 applica nts 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. The City is seeking written
confirmation that the Phase 1 grant award will not be withdrawn.
In consideration of the FEMA Advisory, the City submitted a Notice of Intent (NOI) to apply
for FEMA’s 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.
Source Water/Hydrology and Hydraulics Study (Landslide Drainage Study)
The City Council previously requested a study into the source of water contributing to land
movement, including water originating outside City limits and from upper watersheds , to
determine if runoff could be re-routed before it reached the landslide area so that it would
not infiltrate and contribute to land movement.
30
In response to this request, staff presented a professional services agreement for a
hydrology and hydraulics study for the City Council’s consideration at its May 6, 2025
meeting. The scope of the work was generally to map the watersheds contributing to the
Landslide Complex, identify drainage features, and determine if surface runoff can be re -
routed without adverse impacts. This scope would be the first step of the work related to
landslide drainage and additional steps could be prudent, depending on the outcome of
the first step.
At the May 6, 2025 meeting, the City Council directed staff to obtain a scope of work and
fee estimate to include a sub-surface study to characterize groundwater conditions, which
was originally recommended by a resident. The purpose of such a sub-surface study is
to inform long-term remediation efforts by characterizing potential groundwater sources,
identifying upwelling zones, assessing groundwater flow directions, and delineating the
geometry of the slide plane and bentonite layer(s). The data can then be used to create
a three-dimensional visualization of groundwater conditions to inform siting of potential
dewatering infrastructure.
Staff is in the process of finalizing a scope and fee to present to the City Council for their
consideration at the next Landslide Complex update on August 19, 2025.
Landslide Working Group
On September 27, 2023, the City began (virtually) hosting a weekly landslide working
group meeting open to the utility companies, Geologic Hazard Abatement Districts
(GHADs), homeowners associations (HOAs), other stakeholders such as the Palos
Verdes Peninsula Land Conservancy and Wayfarers Chapel, and the public. The
meetings were a forum for the City and other agencies to provide updates and answer
questions.
After approximately one year of these weekly meetings, s ome utilities informed the City
that they would no longer be willing to participate in these meetings on a weekly basis but
would participate on an approximately bi-monthly basis and would meet with agencies
only. On October 9, 2024, the City transitioned the weekly landslide working group
meetings to be held on the first and third Wednesday of every month and continued to
meet with agencies on the second and fourth Wednesday of every month.
To increase efficiency, on June 25, 2025, the City discontinued the agency meetings that
were being held on the second and fourth Wednesday of every month and will instead
meet with agencies on an as-needed basis. The public meetings on the first and third
Wednesday of every month will continue indefinitely.
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
31
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 is now the upper portion of the ACL at an average of 1.5 feet
per month (about 4 inches per week); however, the area of the ACL moving at this
rate continues to shrink, most likely in response to recent deep dewatering 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, eight ACLAD DDWs are operational as of June 20, 2025,
and two monitoring wells have been installed. Three additional DDWs are expected to be
operational in the coming weeks. ACLAD estimates that the current dewatering rate
among all wells is approximately 35 gallons per minute. 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,
and extend the de-energization emergency declaration for an additional 60 days.
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.

A RESOLUTION OF THE CITY COUNCIL OF THE
CITY OF RANCHO PALOS VERDES, EXTENDING
FOR A TERM OF SIXTY (60) DAYS THE
TEMPORARILY PROHIBITION ON TRAVEL BY
UNICYCLES, BICYCLES, MOTORCYCLES, AND
OTHER ONE- OR TWO-WHEELED VEHICLES ON
PALOS VERDES DRIVE SOUTH WITHIN THE
LANDSLIDE COMPLEX DUE TO CONTINUED
ROADWAY CONDITIONS
WHEREAS, the Greater Portuguese Bend Landslide Complex (t he
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 groun d movement features have continued
to enlarge, expand, widen, or grow depending on the type of feature and location ,
A-1
Resolution No. 2025-__
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
the City Council upon a majority vote.

SHUT OFFS AS ESTABLISHED BY RESOLUTION NOS.
2024-52 AND 2024-57 FOR AN ADDITIONAL 60 DAYS
WHEREAS, the City of Rancho Palos Verdes is home to four out of five sub -slides
that comprise the Greater Portuguese Landslide Complex (Landslide Complex): the
Portuguese Bend Landslide, Abalone Cove Landslide, Klondike Canyon Landslide, and
Beach Club Landslide. The Portuguese Bend Landslide encompasses the Portuguese
Bend Community Association (PBCA), the Seaview Neighborhood (Seaview), and the
Portuguese Bend Beach Club (PBBC). The Landslide Complex has been active since the
1950s;
WHEREAS, the 2022-2023 rainy season brought exceptional amounts of rain to
the region, dumping 20.9” of rain or 190% of the average annual rainfall in the region ;
WHEREAS, by April 26, 2024, total rainfall for the 2023-24 season (beginning Oct
1, 2023) was 23.01" or 169% of the historical 67-year average of 13.63" for this rain
gauge. (All data based on LACDPW Rainfall Gauge No. 1011B at Rolling Hills FS.);
WHEREAS, beginning in 2018, but particularly since May 2023, the land
movement in the Landslide Complex has increased significantly due to increased rainfall
in the last two rainy seasons, which caused the water table to rise dramatically and
destabilize the landslides. The City has established, via repeated geologic studies, that a
significant factor in the speed of land movement in the Landslide Complex is the amount
of water in the soil;
WHEREAS, on October 3, 2023, the City Council of the City of Rancho Palos
Verdes adopted Resolution No. 2023-47, declaring a local state of emergency due to the
alarming increase of land movement in the Landslide Complex. The state of emergency
based on the land movement has been extended as required by law and is still active;
WHEREAS, on August 6, 2024, the City Council by unanimous vote adopted
