EXECUTIVE SUMMARY:
City Council is being asked to receive and file an update on the Landside
Complex conditions, activities, and financials. City Council is being asked to
extend the temporary prohibition or one- or two-wheeled vehicles on Palos
Verdes Drive South, continue the local emergency, and continue the local de -
energization emergency for 60 days due to continuing landslide conditions.
•Following are key dewatering program updates:
o 16 operational ACLAD wells pumped a total of approximately 5 million
gallons of water in the month of September 2025.
o 8 operational City DDWs pumping approximately 28.5 million gallons of
water per month.
3
o 2 operational KCLAD DDWs, pumping approximately 12.5 million gallons
per month.
• Following are key winterization updates:
o City winterization of Upper Altamira Canyon is in progress and expected to
conclude in late November/early December 2025.
o ACLAD is preparing to begin winterization work on the Palos Verdes Drive
South (PVDS) culvert and on Lower Altamira Canyon (seaward of PVDS)
using City loan funds and a City financial contribution not to exceed
$200,000.
o Winterization of Portuguese Canyon is starting in the coming days with
completion expected in late November/early December 2025.
o Winterization of Klondike Canyon and Seaview is complete and
maintenance is ongoing.
• Following are key movement rate updates:
o ACL decelerated average of 29% to 0.70 feet/month from August 5 to
October 3, 2025; with current movement rate approximately 14 times the
October 2022 pre-deep slip plane activation rate.
o PBL decelerated average of 26% to 0.43 feet/month from August 5 to
October 3, 2025; with current movement rate approximately 7 times the
October 2022 pre-deep slip plane activation rate.
o KCL continues to show no measurable movement.
• Following are key financial updates:
o As of October 20, 2025, a total of $5.8 million or 36% of the total budget for
FY 2025-26 has been spent or encumbered, including $1.6 million (10%)
spent and $4.2 million (26%) encumbered.
o The projected restricted CIP Fund Balance increased by $5.8 million (from
$2.1 million to $7.9 million), net of reserves. This is due to a $2.1 million
expenditure budget reduction, $4 million in added revenues from the Los
Angeles County Sanitation District No. 2, and deferral of ACLAD and
KCLAD loan payments totaling $342,900 to December 2026.
• City Council is being asked to approve KCLAD’s request to amend the loan
agreement by extending the first loan payment of $186,932 from December 1,
2025 to December 1, 2026. This request is consistent with ACLAD’s extension
previously approved by the City Council in March 2025.
• City Council is being asked to extend the temporary prohibition or one - or two-
wheeled vehicles on Palos Verdes Drive South, continue the local emergency, and
continue the local de-energization emergency for 60 days due to continuing
landslide conditions.
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) and
4
includes areas uphill from the PBL and ACL, within the Landslide Complex as mapped by
various agencies.
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 November 15, 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 the 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 May 6, 2025, the City Council received a summary of the status of the DDW and
winterization programs.
On September 16, 2025, the City Council modified the FY 2025-26 landslide emergency
response budget for several projects/activities resulting in an overall reduction of
$2,168,000, to preserve funding for future year operations and maintenance of landslide
measures. Additionally, the City Council authorized the use of the City’s winterization
contingency of $200,000 to pay for 50% of the cost of repairing the culvert under PVDS
and 100% of the cost of Lower Altamira Canyon winterization. (Attachment D)
This report will serve as the 60-day standing report on the current conditions of the
Landslide Complex and consideration to extend the local state of emergency and
prohibition of one- and two-wheeled vehicles along PVDS through the Landslide
Complex.

Recent GPS survey data published by McGee Surveying Consulting for the approximately
“monthly” monitoring periods ending September 3, 2025 and October 2, 2025 were
reviewed and analyzed (Attachment E).
Figures 1 and 2, on the following page, present scaled displacement rates (i.e., movement
velocities), movement vectors, and contours (aka “heat maps”) of displacement rates for
the September 3, 2025 and October 2, 2025 full monitoring periods.
Figure 3, on the following page, provides contours of landslide displacement rate change
since March 9, 2025, which provides perspective on which areas of the landslide complex
are decelerating the fastest within a specified period of time.
Table 1 provides a summary of movement rates for each sub -slide over time.

*Month of emergency declaration
**Month of peak movement rate
For all points monitored across the entire Landslide Complex, the following are the key
conclusions for the time period of August 5 through October 2, 2025:
• The average movement rate for all points still moving within the active landslide
boundary is 1.45 inches/week.
• The ACL movement, within its historical boundary, has decelerated an average of
approximately 29% between August 5 and October 3, 2025. The average rate of
movement for these points was 0.70 ft/month from August 5 through October 3,
2025. The ACL movement has decelerated an average of 82% since the deep
dewatering program commenced mid-September 2024. The fastest moving area
8
remains the upper portion of the ACL at 1.79 feet per month (about 2.2 inches per
week). As can be seen in Figure 3, previous page, the ACL has exhibited the
highest reductions in landslide velocity between March 9 and October 3, 2025; this
is believed to be due to the recent deep dewatering program implemented by
ACLAD.
• The PBL, within its historical boundary, has decelerated an average of 2 6% from
August 5 through October 3, 2025. The average rate of movement for these points
was 0.43 ft/month from August 5, 2025 through October 3, 2025. The PBL
movement has decelerated an average of 87% 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
2025, the GPS monitoring data indicate that the PBL has been steadily
decelerating.
• The KCL has not moved for a period of one year now (i.e., no measurable
movement since mid-October 2024). Although some points in the KCL have
periodically shown 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 30% from August 5 through October 3, 2025. The
average rate of movement for these points was 0.63 ft/month from August 5
through October 3, 2025. The Greater Portuguese Bend/Ancient Altamira
Landslide Complex points have decelerated an average of 81% 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 and the 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.
9
• 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.
• Point AB76, just inside the far west margin of the landslide on the York property,
ceased moving as of March 2025.
Open Space, Palos Verdes Nature Preserve, Trails, and Beach Conditions
Current trail and beach closure conditions remain the same as enumerated in th e
September 16, 2025 report (Attachment D). Sixteen miles of trails within the Portuguese
Bend, Filiorum, and Abalone Cove Reserves, as well as the open space area around the
Archery Range remain temporarily closed due to landslide-related damage or abatement
work. For the same reasons, three public beaches (Abalone Cove Beach, Sacred Cove
Beach, and the beach below the Archery Club) remain closed.
However, staff has been working with the City Geologist to identify approximately five
miles of trails in upper Portuguese Bend and Filiorum Reserves that are outside of the
active moving landslide area and that have stabilized sufficiently for reopening by
approximately December 1, 2025. These five miles of trails are shown in bright green on
the map in Figure 4 below. City and Palos Verdes Peninsula Land Conservancy (Land
Conservancy) Staff have partnered and have been working hard to repair these five miles
of trails in preparation for reopening. Components of the reopening plan include
reactivating the ParkMobile parking solution, meeting with affected homeowner
associations near Burma Rd. and Rattlesnake Trailheads, an active education and
enforcement campaign, and continuous monitoring in coordination with the Cit y Geologist
for safety.
The five miles of trails to be reopened will provide enjoyable loops for passive recreation
and will restore pedestrian and equestrian access from the Portuguese Bend Community
to upper Portuguese Bend and Filiorum Reserves. At the September 16, 2025 City
Council meeting, members of the Portuguese Bend Community expressed a strong
desire to use the trails located in the 96-acre Wildlife Corridor acquired in 2022. More
information on this topic is included in the Additional Information section of the staff report.

Following are key observations on the current status of DDW operations:
• DDW-9A is currently offline due to a low water level. The City’s geologist team is
studying how quickly its water level rises and will then recommend adjustments to the
pump’s operation to minimize the risk of it running dry and burning out.
• DDW11 has 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 operation costs, 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
under the deep slip plane as well as under the shallow slip plane to measure uplift
pressure on each slip plane. The locations of the piezometers can be found in the August
19, 2025 staff report.
Chart 1 shows water pressures from the piezometers installed under the deep slip plane
and Chart 2, following page, 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.
Chart 1: PBL Deep Slip Plane Water Pressure
12
Chart 2: PBL Mid-Deep Slip Plane Water Pressure
For those piezometers near the DDWs in both the PBL (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, continued to show a relatively constant decreasing pressure
drop over time, which correlates to reduced surface movement in nearby GPS survey
points. There was a slight uptick in pressure beginning in August which is due to reduced
pumping caused by maintenance issues and well re-drilling. Decreasing pressure trends
are now continuing with wells back on-line.
The piezometers far away from DDWs (E-2-2 and E-2-5) show no to only a slight
decrease in pressure over the last four months or so. The slight reduction shown in
piezometers E-2-2 and E-2-5 is likely the result of drying conditions and below normal
rainfall and the achievement of a steady state pressure condition. It is notable that
piezometer P-2, where there is water pumping, is experiencing a continual drop in
pressure; while piezometers E-2-2 and E-2-5, where there is no water pumping, do not.
Emergency Winterization Projects Status
Upper Altamira Canyon
Work has started on re-grading the side of the canyon that is closing in on the other side
and adding a pipe in the canyon. This will temporarily close fissures and provide for some
water flow through the pipe. This work will minimize runoff from recharging the ground
water table in anticipation of dewatering wells continuing to reduce the rate of movement.
The work is expected to be completed by the end of November to early December 2025.
Staff notes that there remains a risk that the pipe may be crushed again as the canyon
may close in on itself before the end of the rainy season and it is not likely that the pipe
13
could be maintained after rains because conditions may become unsuitable for
equipment. If conditions remain suitable for pipe repairs, there would be additional costs
for the maintenance work beyond the current approved budget that the City Council may
be asked to consider.
Kelvin Canyon
Grading from the FY 2024-25 emergency winterization remains in good condition.
Maintenance of the existing winterization will be performed on an as-needed basis, with
the first effort to begin in November 2025.
Klondike Canyon
Grading, pond liner, and erosion control measures from the FY 2024 -25 emergency
winterization remain in good condition; with only re-securing of the pond liner, re-setting
of some sandbags, and installation of some additional erosion control measures needed.
The work is expected to be completed by the end of November 2025.
Fissure Filling/Portuguese Canyon
Mobilization has started to install a temporary pipe to convey water from the depressed
area above Burma Road Trail to lower areas of the landslide. This work will prevent water
from ponding above the Burma Road Trail and keep it free flowing, thereby reducing
opportunities for infiltration at the head of the landslide. The work is expected to be
completed by the end of November to early December 2025.
Seaview Neighborhood
Re-graded and paved streets, storm water capture inlets, drainage pipes, and graben
liners from the FY 2024-25 winterization remain in good condition. Staff revaluated
conditions during and after the October 14, 2025 rain event and found that all winterization
elements functioned appropriately. Based on feedback from residents, Staff are
evaluating enhancements to drainage elements of winterization. Maintenance work and
storm response will be ongoing throughout the 2025-26 rainy season.
ACLAD Update
Following is a summary status of the ACLAD’s activities as of October 27, 2025. The
locations of ACLAD dewatering wells can be found in the August 19, 2025 staff report.
• ACLAD currently has 16 operational wells (a combination of original wells and new
DDWs) that have pumped a total of approximately 5 million gallons of water in the
month of September 2025.
o 7 original wells extracted approximately 1.5 million gallons of water.
o 9 DDWs extracted approximately 3.5 million gallons of water.
• Wells do not operate during the evening hours due to the use of generators.
o Approximately half of wells run dry by early afternoon and do not pump
overnight while water recharges.
• Pumping rates overall continue to decline month-over-month as wells are running
dry.
14
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. The locations of the piezometers can be
found in the August 19, 2025 staff report. 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.
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
[CONTINUED ON NEXT PAGE]
15
Chart 4: ACLAD Mid-Deep Slip Plane Water Pressure
The plots for those piezometers near the DDWs in the ACL (Alta 8 and Alta9), show a
marked decrease in pressure immediately following the start of the DDW program. The
direct correlation between pumping rates/volumes and pressure decrease is pronounced.
While there was a continuous decreasing trend with the initiation and continuance of
pumping on nearby wells, reciprocally there was a sharp rise in water pressure
measurements when nearby wells ceased operation due to maintenance issues (some
of which resulted in cessation of pumping for 3 weeks or more). Sharp pressure rises are
evident on the ACL plots during this time period.
Additionally, the City is conducting mid-month GPS surveys of monitoring points in the
vicinity of the recently installed ACLAD DDW’s, to further assess the effectiveness of
ACLAD’s DDWs in slowing the land movement. A prominent deceleration of ACL and
Altamira monitoring points occurred after about July 1, 2025 compared to the period prior
to July 1, 2025. This is interpreted to be a response to the last four ACLAD DDW’s coming
online, specifically DDW29 on 6/25/25, DDW21 on 6/30/25, DDW22 on 7/3/25, and
DDW8 on 7/11/25. Of particular note is a significant deceleration in movement velocity
for GPS monuments AB57, AB58 and AB59 from July to October, compared to other
monuments. This deceleration is illustrated in Chart 5 a on the next page.

Chart 5a: ACLAD DDW Dewatering Impact on Land Movement
To further analyze the impact of ACLAD’s DDW program on land movement; piezometric
surfaces for the shallow and middle piezometers of monitoring well Alta -8, which is next
to pumping well DDW-29, were plotted in Chart5b. The plot shows average horizontal
movement velocity for the closest 12 GPS points. The chart also shows when the various
ACLAD DDWs came online. An abrupt decline in piezometric pressure for the middle
piezometer in Alta-8 occurred around May 1st, 2025, after DDW's 24, 26, 27 and 28 came
online (with DDW-16B and 25 already online), and there was an accompanying decrease
in movement velocity as of the May 1st GPS readings. Similarly, there is a strong
correlation observed between the decline in piezometric pressure for the shallow
piezometer, and decrease in movement velocity, particularly notable around the middle
of March 2025 but then significantly dropping around the beginning of July when DDW -
29 came online. DDW29 went offline on October 10 due to a generator issue, and there
is an immediate response seen, with rising piezometric levels for both the shallow and
middle piezometers in Alta-8, until the pumping was restarted on October 22. This is a
clear indication that DDW29 is reducing groundwater levels (expressed as piezometric
surfaces) in multiple hydrogeologic regimes (i.e. aquifers) that do not appear to be
hydraulically connected but are both penetrated by the monitoring well as well as the
dewatering well, and this has cut the landslide movement velocity by about 50% since
April of this year.
17
Chart 5b: ACLAD DDW Dewatering Impact on Land Movement
ACLAD identified significant damage to the Altamira Canyon culvert from above Narcissa
Drive and seaward of PVDS, which is the primary drain for Altamira Canyon under PVDS.
The culvert is 10 feet in diameter and approximately 670 feet in length. The damage
includes deviation and separations that allow water to infiltrate into the ground and
recharge the water table. ACLAD, in consultation with Staff and the project geologists,
determined that repairs can be made to keep the culvert consisting of patching/filling
separated areas. The cost is estimated to be in the range of $100,000.
Additionally, ACLAD found that Lower Altamira Canyon, which conveys runoff to the
ocean, is obstructed due to land movement. ACLAD, in consultation with Staff and the
project geologists, determined that lower Altamira Canyon can be re -graded to keep the
channel open to allow the flow of runoff water to drain into the ocean, the cost of which is
estimated to be in the range of $100,000.
In addition to the construction costs, there are environmental compliance costs
associated with this work. Although ACLAD is exempt from CEQA because it is a geologic
hazard abatement district (GHAD), ACLAD remains subject to requirements associated
with the Natural Communities Conservation Plan (NCCP)/Habitat Conservation Plan
(HCP), particularly with respect to documenting impacts of emergency work. Furthermore,
an emergency waiver should be filed with the Coastal Commission, and a notice of intent
should be filed with the Water Quality Control Board, among other coordination measures.
The cost of environmental compliance for Lower Altamira Canyon emergency
winterization is estimated to be approximately $40,000.
On September 16, 2025, the City Council authorized the use of the City’s winterization
contingency of $200,000 to pay for 50% of the cost culvert repairs and 100% of the cost
18
of Lower Altamira Canyon winterization. The City’s total cost would be within the $200,000
allocation, including environmental compliance.
On October 7, 2025, the City Council amended the City’s loan agreement with ACLAD to
authorize culvert repairs as an eligible use of the loan funds by ACLAD. This action allows
ACLAD to use the loan to pay for the remaining 50% of the cost of repairing the culvert.
ACLAD intends to contract directly for the construction work, which is expected to begin
on or around November 5, 2025 and be complete by the end of November to early
December 2025. ACLAD has requested that the City contract directly with specialized
consulting firms for the environmental compliance work.
KCLAD Update
Following is the status of KCLAD’s activities as of October 22, 2025. The locations of
KCLAD dewatering wells can be found in the August 19, 2025 staff report.
• Two of three KCLAD wells are operational and extracting water at a rate of 287
gallons per minute:
o KCLAD Well #5: pump depth at 133 feet; water depth at 103 feet; pumping
rate at 51 gallons per minute.
o KCLAD Well #7: pump depth at 175 feet; water depth at 163 feet; pumping
rate at 236 gallons per minute.
• KCLAD Well #6, with a pump set at a depth of 154 feet and a water depth of 127
feet, is temporarily offline due to low water levels.
• Shallow KCALD wells #3 and #4, are out of order.
• Weekly readings are uploaded to the KCLAD website (KCGHAD.org).
KCLAD and Staff continue to coordinate on drainage and winterization efforts related to
receiving flow from Klondike Canyon.
Utility Updates
Southern California Gas Company (SoCalGas)
Following are SoCalGas updates since the September 16, 2025 staff report:
• 15 homes in Seaview have had gas service restored. At this time, there is no
indication when gas service will be restored in the PBCA.
Southern California Edison (SCE)
Following are SCE updates since the September 16, 2025 staff report:
• 11 homes in the PBBC and Seaview communities remain without power and are
awaiting electrical inspection. SCE will re-energize the remaining homes on a
weekly basis upon successful completion of electrical inspection.
• As part of ongoing efforts to enhance the resiliency and reliability of SCE
infrastructure, SCE began installing an innovative solution - Tension Relief
Strategy - in the Seaview neighborhood, as well as other areas of the Palos Verdes
Peninsula. More information can be found at: Energized.edison.com/rpv
19
As a separate item, on September 16, 2025, City Council approved relocating the
temporary power pole at the Ladera Linda Community Park with a new permanent
electrical service alignment consisting of overhead lines and poles. SCE is currently
finalizing the design of the overhead option and will start construction in the coming
months after permits are issued by Public Works.
Sanitary Sewer – Portuguese Bend Community
The City continues to make repairs to the Abalone Cove Sanitary Sewer System (Ab Cove
Sewer) as line breaks or pump malfunctions are discovered.
Sanitary Sewer – Seaview Neighborhood
There are currently no activities related to the Seaview Sanitary sewer as there has been
no detectable land movement for many months.
Sanitary Sewer – Portuguese Bend Beach Club (PBBC)
There are currently no activities to report for the privately owned PBBC sanitary sewer.
Sanitary Sewer – PVDS Trunk Lines
Replacement of the sewer trunk lines along PVDS with more flexible material is now
complete.
California Water Service (Cal Water)
Following are Cal Water updates since the September 16, 2025 staff report:
Throughout the Landslide Complex, Cal Water is currently in the process of bringing the
following sections of water lines above-ground:
• Sweetbay Road:
o Construction is scheduled to be completed by the end of the October , with
paving to be completed promptly, thereafter.
Communications
Following are Communications updates since the September 16, 2025 staff report
(Attachment D):
• Frontier’s new fiber optic route to the PBCA will likely require a new utility easement
over the Wildlife Corridor, located in the Palos Verdes Nature Preserve, which the
City acquired with Federal Section 6 grant funding for wildlife conservation. For
this reason, the City will need to coordinate with the US Fish and Wildlife Service
and California Department of Fish and Wildlife on placing a new utility easement
over the property.
• Based on discussions with the Land Conservancy, Frontier is currently updating
their proposed communications (fiber optic) route. Staff will continue to work with
Frontier on securing agreements/permits required for installation in the coming
months.

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 8a and 8b on the following page
is a summary of expenditures that were used for the loan ending July 2025. Financial
information was provided by the districts.
For ACLAD, as of September 30, 2025, $1,484,492 or 92% of the loan have been spent
(Table 8a). Majority of the loan amount (99%) was used for the new well maintenance
and operations. Of the 99% in maintenance and operations, 77% were used for well
drilling and pumps and 22% were for well service and parts. The remaining expenses are
from power utilities, propane, diesel, and generators. In accordance with the loan
agreement, no expenditures were made on legal services. Legal service expenses
incurred by ACLAD were paid from their annual operating budget.

2. KCLAD Loan Agreement
On February 4, 2025, the City Council affirmed using the $1,917,500 City loan to KCLAD
to implement its stabilization projects. Subsequently, in March 2025, both ACLAD and
KCLAD submitted a request to extend the first loan payment to the City from December
1, 2025 to December 1, 2026, to allow the use of current-year revenues for stabilizing the
landslide. The City Council approved ACLAD’s extension on March 18, 2025, along with
the scope of work for ACLAD’s DDW project.
With ACLAD’s amendment completed, Staff now requests City Council approval of
Amendment No. 1 to the Loan Agreement between the City and KCLAD for the Klondike
Canyon Subslide of the Portuguese Bend Landslide Stabilization Project (Attachment G).
3. Bicycle, Motorcycle, Unicycle and Other Similar Wheeled Vehicle Prohibition
The City Council is being asked to extend the existing resolution prohibiting one- or two-
wheeled vehicles on PVDS for an additional 60 days (Attachment A).
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 nearly two 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.
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.
4. Extension of the Local Emergency Declaration
The City Council is being asked to adopt the attached resolution thereby extending the
Declaration of Local Emergency by 60 days (Attachment B).
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.
26
The City Council has extended the local emergency on multiple occasions within the 60 -
day window and it remains in effect until November 15, 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 January 3, 2026 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 December 16, 2025.
5. Extension of the Local Emergency Declaration for Utility Shutoffs
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).
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 November 15,
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 January 3, 2026,
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 December 16, 2025.
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.
Public Trail Use within the Wildlife Corridor
At the September 16, 2025 City Council Meeting, Portuguese Bend Community neighbors
expressed the hardship that their neighborhood and members of the equestrian
community are experiencing due to loss of access to approximately 6 miles of trails
connecting their community into the Portuguese Bend and Filiorum Reserves. Some of
27
the requests made at the meeting included allowing certain subsets of the community to
use the closed trails within the landslide area, and to allow the trails within the Wildlife
Corridor to be available for public use.
The trails temporarily closed by the City Manager within the Preserve and adjacent open
space areas have been closed at the advisement of the City Geologist due to land
instability and for public safety. Additionally, the closures have been conducted in close
coordination with the City’s landslide team, Joint Powers Insurance Authority Risk
advisors, California Coastal Commission, Land Conservancy, U.S. Fish and Wildlife
Service (USFWS), and California Department of Fish and Wildlife (CDFW). Because the
closures are in place for public safety, the City would not grant any passive recreational
access at this time.
It was also requested that the City open up the 2022-acquired Wildlife Corridor for public
access, given the unanticipated and extensive landslide-related closures in the vicinity.
The City’s NCCP/HCP adopted by the City Council in 2019, establishes the Palos Verdes
Nature Preserve in a configuration to maximize habitat conservation and connectivity.
Included in its design is the Wildlife Corridor, then privately owned, to connect the inland
Preserve properties of Three Sisters, Filiorum, Portuguese Bend, and Forrestal Reserves
to the coast and coastal Abalone Cove Reserve. The primary purpose of this property
was envisioned as a corridor for movement and benefit of sensitive species. The City was
able to acquire the 96-acre Wildlife Corridor in 2022 utilizing the following funding
sources:
• U.S. Fish and Wildlife Service: $12,600,000
• Wildlife Conservation Board: $4,800,000
• Land Conservancy (private donations): $1,300,000
• City of Rancho Palos Verdes: $1,300,000
• LA County Regional Park and Open Space District: $1,000,000
The grant agreements between the City and USFWS and City and Wildlife Conservation
Board, expressly establish that the primary purpose of the Wildlife Corridor is the
propagation of sensitive species and their habitats. The grant agreements permit only two
public access trails on the properties: Plumtree Trail, which is a pedestrian -equestrian
trail connecting the Portuguese Bend Community to the Filiorum Reserve, and a segment
of a connector trail that would cross the northwestern corner of the Wildlife Corridor and
connect Three Sisters Reserve to Filiorum Reserve.
The City implemented Plumtree Trail in 2023 and is currently seeking grant funding to
help analyze a canyon crossing to implement the connector trail. At a September 23, 2025
meeting between the City, USFWS, CDFW, and Land Conservancy, the City explained
the impact profound and long-term trail closures are having on the Portuguese Bend
Community and inquired about the possibility of opening trails within the Wildlife Corridor
for expanded public use long-term, or temporarily. The USFWS shared that public access
would have a significant negative impact on the Wildlife Corridor and is contrary to the
purpose of its intention and acquisition. While the suggestion is currently under
consideration, it was made clear that it is not likely to be acceptable.

Hydrology & Hydraulics Study Update
On September 16, 2025, the City Council awarded a professional services agreement to
Geosyntec Consultants, Inc. (Geosyntec) for a comprehensive hydrology and hydraulics
study of the Landslide Complex.
The general scope of the study is the following, with further detail in Attachment F:
• Develop a Hydrology and Hydraulics (H&H) model for the entire Landslide
Complex watershed that incorporates storm patterns from the last ten years, with
future rainfall data collection to field validate the model.
• Prepare planning level concepts for alternatives to reduce stormwater infiltration
into the Landslide Complex including schematic layouts, cost opinions, real estate
needs, utility impacts, and permit requirements.
• Conduct a subsurface conditions study of the PBL to characterize primary
groundwater flow paths and geologic conduits.
On October 13, 2025, after contract signatures were received and insurance documents
were submitted, Staff directed Geosyntec to begin work.
The hydrology and hydraulics model (excluding future rainfall data collection for field
validation), planning level concepts, and geophysical study are scheduled to be
completed in approximately six months from the start date, with rainfall data collection
continuing for approximately three years beyond that time.
Study to Create a Toll Road on PVDS
On October 21, 2025 the City Council considered initiating a study to determine the
feasibility of converting PVDS into a toll road to provide a funding source for landslide
remediation and management efforts to keep PVDS operational.
After considering the multiple layers of legal, procedural, and regulatory approvals
needed; the City Council directed Staff to work with the Fiscal Sustainability
Subcommittee to determine if and where a PVDS toll road would rank among the list of
possible new revenue sources before committing to spend funds on a feasibility study.
Disaster Cost Recovery Applications Update (FEMA and CalOES)
As previously noted 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, which total $61.4 million. Of this amount, $39.4
million is public assistance (City) and $22 million of individual assistance (residents).
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
29
deemed eligible, the reimbursement process could take anywhere from one to three years
before the City receives the funds.
In January 2025, 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. 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.
On March 17, 2025, pursuant to the Stafford Act and Code of Federal Regulations, the
City filed appeals of the first seven denial letters, and on April 25, 2025, the City filed a
remaining appeal letter. The appeals are heard by FEMA’s District 9 Administrator, Robert
Fenton, and his decision is then appealable to FEMA’s Headquarters in Washington D.C.
Obligated Funds from FEMA ($574,335 as of October 2025):
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 continued to coordinate with
both FEMA and CalOES to facilitate reimbursement. Subsequently on October 10, 2025,
FEMA notified the City that $574,335 has been obligated and forwarded to CalOES for
the reimbursement process, as summarized below:
Obligated Funds from FEMA – Public Assistance from Winter Storms (Jan. 31, 2024 - Feb. 9, 2024)
Projects Denied from FEMA ($37,775,258 as of October 2025)
On October 10, 2025 (dated October 3, 2025), the City received a response to the appeal
letters from FEMA Regional Administrator Robert Fenton, denying the City’s appeals for
$37.77 million. The denial was based on the following determinations:
• Applicant did not demonstrate the claimed work required as a result of the
declared disaster.
• Due to pre-existing instability, permanent repairs are not eligible.

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. Both ACLAD and KCLAD received similar notifications that their appeals were
denied by District No. 9 Administrator Mr. Bob Fenton. ACLAD and KCLAD are
collaborating with the City to file a second and final appeal to FEMA Headquarters.
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.
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 (14 red-tagged, and 8 yellow-tagged) in the first round of program funding. All
remaining eligible applications will be considered for any future rounds of program
funding.
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
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 anticipation of the FEMA grant award, the City issued a request for proposals to hire a
qualified FEMA Project and Grant Manager with expertise in working with the intricate
requirements of FEMA and HMGP. The City Council awarded this contract at its meeting
on October 7th, 2025. By engaging a project manager with FEMA and Hazard Mitigation
expertise and understanding the processes and timelines associated with FEMA grant
administration, will ensure compliance with the guidelines issued by the HMGP funds for
the Program and help ensure that we are processing applications as quickly as possible
for residents.
33
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 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:
The ACLAD, City, and KCLAD dewatering well programs are currently operating 16, eight,
and two DDWs, respectively. ACLAD pumped a total of approximately 5 million gallons
of water for the month of September 2025, the City is pumping an average of
approximately 660 gallons per minute, and KCLAD is pumping approximately 287 gallons
per minute.
City winterization of Upper Altamira Canyon is in progress and expected to conclude in
late November/early December 2025 while ACLAD is preparing to begin winterization
work on the Palos Verdes Drive South culvert and on Lower Altamira Canyon using City
loan funds and a City financial contribution not to exceed $200,000. Winterization of
Portuguese Canyon is starting with completion expected in late November/early
December 2025. Klondike Canyon and Seaview winterization is complete with
maintenance ongoing.
The ACL decelerated an average of 29% to 0.70 feet/month from August 5 to October 3,
2025; which means the current movement rate approximately 14 times the October 2022
pre-deep slip plane activation rate. For the PBL, deceleration was an average of 26% to
0.43 feet/month from August 5 to October 3, 2025; and the current movement rate
approximately 7 times the October 2022 pre-deep slip plane activation rate. The KCL
continues to show no measurable movement.
As of October 20, 2025, a total of $5.8 million or 36% of the total budget has been spent
or encumbered, including $1.6 million (10%) spent and $4.2 million (26%) encumbered.
The City Council is being asked to approve KCLAD’s request to amend their loan
agreement by extending the first loan payment of $186,932 from December 1, 2025, to
December 1, 2026. This request is consistent with ACLAD’s extension previously
approved by the City Council in March 2025.
34
Based on currently available data, Staff recommends extending the local state of
emergency and prohibition of one- and two-wheeled vehicles along Palos Verdes Drive
South through the Landslide Complex.
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.

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.

Portuguese Bend Land Movement Monitoring Surveys
Survey Reports for September 17, 2025 to the Current October 2, 2025 Survey
for the
City of Rancho Palos Verdes
prepared by
McGee Surveying Consulting
Portuguese Bend was monitored for land movement on a tri-annual basis with the initial surveys of 65-70 points
at the beginning of the rainy season (October 1) of each year followed by two subsequent partial Winter and
partial Spring Monitoring Surveys of 30-40 points. In past years, an annual survey report was published
following the spring survey on file with the City. Land movement begin to increase about 2019 and substantially
accelerated after 2022. Beginning in early 2024 the surveys were conducted every six weeks, then every month,
and then weekly. Land Movement has now substantially slowed. Presently a full survey of about 100 points is
conducted at the beginning of each month and a partial survey of about 20 points at mid-month. This document
addresses metadata relative to the surveys and individual surveys are addressed in more detail as addendums.
The movement results for each survey are listed in the attached “PB MOVEMENT DATA POSTING No.2…
.xlsx” spreadsheet. The spreadsheet (No. 2) begins with survey M83 in mid- September 2025. The previous
spreadsheet reported surveys M01 to M83 from 2007 to September 17, 2025. The movements are reported for
the average date of the surveys.
List of Reported Monitoring Surveys
M83 Partial Survey - September 17, 2025 (Page 5)
M84 Full Survey - October 2, 2025
OVERVIEW: McGee Surveying Consulting (MSC) has performed the land movement monitoring surveys at
Portuguese Bend since 2007. The planning and coordination of the surveys is overseen by Michael McGee,
PLS3945 of MSC who is responsible for the execution of the field surveys, processing observations, network
adjustments, analysis, and reports. For a general history, details and procedures utilized in this survey but not re-
stated here, see the “Portuguese Bend Land Movement 2020-2021 Monitoring Survey” Report dated October 5,
2021, revised and published May 11, 2022 followed by “Portuguese Bend Land Movement Monitoring Survey
Report” dated October 10, 2023 through September 4, 2025. See also prior annual reports dating back to 2007.
About 100 monitoring and five control reference points are presently included in the surveys. PVE3 and other
CSRC CGPS (CGNSS) stations, discussed later, are used to reference the survey network, and verify the
recovery of the reference frame. Increased velocities of movement were detected about 2019 and substantial
accelerations in the Spring of 2023. Up until 2023 about 70 points were monitored. Since then, about 30
additional points have been added to properly assess and distinguish the land movement. The new points and
points lost due to the slide or mediation measures are noted in the above referenced reports and the addendums.

All coordinates and movements of the monitoring surveys are listed in two spreadsheets prepared as a separate
Report document but considered an attachment to this narrative Report. The first spreadsheet
“PB MOVEMENT DATA POSTING M83 2007 to 09-17-2025.xlsx” includes the results of all surveys from
2007 to September 17, 2025. The second spreadsheet is initiated with this report and covers September 17, 2025
forward titled “PB MOVEMENT DATA POSTING No. 2-M83 09-17-25 to (present).xlsx
PROJECT DATUMS - REFERENCE FRAME
Since 2007, the horizontal positions have been based on the North American Datum of 1983 (NAD83) 2007
Adjustment, Epoch 2007.00 and the vertical positions based on the North American Vertical Datum of 1988
(NAVD 88) referred to as the reference frames or datums. A more current NAD83 adjustment and epoch is
available e.g., NAD83 (2011) Epoch 2010.00; however, the 2007 Adjustment at Epoch 2007.00 is retained to
maintain consistent relative positions over time since it is the basis for the initial 2007 survey. The NAVD88
elevations (orthometric heights) are based on measured ellipsoid heights combined with the NGS Geoid03
model to convert ellipsoid heights to elevations. The elevations are referenced to National Geodetic Survey
(NGS) benchmarks. Although the current geoid model is Geoid18, the Geoid03 model is retained to maintain
consistent relative heights over time as explained in the May 2022 Report referred to above. The latitudes and
longitudes are determined by Global Satellite Navigation Systems (GNSS) measurement technology, often
referred to as GPS, and are converted to grid coordinates by projecting into NAD83 California State Plane
Coordinates Zone 5 in US Survey Feet.
A valid recovery of the survey reference frame is essential to accurately measure and assess actual movements
of individual points relative to the greater peninsula outside the slides influence. The method for recovering the
monitoring survey reference frame was modified as reported in 2019 to improve the efficiency of the
processing and analysis of the surveys. Since 2007, GNSS Station PVE3 a California Spatial Reference Center
(CSRC) Continuously Operated GPS Station (CGPS) at City Hall along with other CGPS Stations on the
peninsula have been the anchor for referencing the monitoring surveys and assuring the integrity of the reported
movements. In 2014, a “PK” nail (PVE3RP) was set as a reference point in the concrete base of Station PVE3 to
allow access and indirect measurements of PVE3. The position listed here is based on five years of observations
relative to PVE3.
Pt# Latitude Longitude NAVD88 Ht
PVE3RP 33-44-35.74239 118-24-15.27451 346.88 ft
The procedure for the surveys is to include the reference point PVE3RP (thereby including PVE3) and reference
points RP01, RP02, RP03 and RP05 all located outside of the slide zones to recover and verify the stability of
the reference frame for each survey. Comparing the positions of the reference points with PVE3RP and PVE3 at
City Hall and other CSRC CGPS Stations provides a redundant verification that the reference frame is stable
and successfully recovered.
As stated, the rate of movement (velocities) of the land masses have increased over the past seven years
compared to the 2007-2018 average but substantially slowed in the last year. For more information see
“Assessment of Movements & Accelerations” on Page 11 of the October 2023 Report referred to above.
NETWORK - BASE STATIONS – POINT NAMES
AB61, AB20 and AB73 have previously served as suitable Base Stations for the GNSS instrument (receiver) for
referencing measured positions of the monitoring points. AB61 was suspended several years ago due to its
environmental sensitivity and lack of security. AB20 and AB73 were abandoned due to the continuously
increasing velocities of land movements. Reference Points outside the present active slide zones serve as base
stations since January 2024 for referencing GNSS measurements. The Reference Points are RP02, RP03 and
RP05 located in the near vicinity of each other about 1400 feet northerly of the entrance to Abalone Cove Park
and about ¼ mile westerly of the slide boundary and,
Monitoring point name conventions were established in the early 1990 surveys by others. The points are named
for the slides they fall within. The slide acronyms are AB, PB, KC, CR and FT. The point numbers are
E-3
McGEE SURVEYING CONSULTING
5290 Overpass Road, Ste#107, Santa Barbara, CA 93111
Page 4 of 7
incremented as new points are established to replace abandoned or destroyed points or expand the network.
Many of the original points are lost or no longer monitored. For data management purposes during each survey
the point names are prefixed with a sequential monitoring number to distinguish successive surveys. For
example, the occupation of AB01 on the 80th monitoring survey is point M80AB01 where M80 indicates the
sequence number since the first M01 Monitoring Survey by MSC in September 2007. The prefix is stripped in
the spreadsheet reports.
GNSS General Survey Parameters, Metadata & Equipment
Date of Initial Survey Report: M83 – September 17, 2025 between 0800-1700 PDST reported as an Addendum here
Constellations & Satellites: GPS (31), Russian GLONASS (23), Galileo (24) and Beidue (40+)
Observables (Carrier Waves): GPS (L1, L2, L5), GLONASS (L1, L2), Beidue (L1, L2); & Galileo (4 Carrier Waves)
Data Epoch Rate - 0.2 seconds (5 Hz) at the Roving Receiver; 1 second at the Base Receiver
Satellites: 20-40; GDOP: < 2; Elevation Mask: 10° at the Base Station; 10° at the Rover
Ephemeris: Broadcast for real time positioning (RTK).
Weather: See Addendums
Space Weather: See Addendums (Boulder K-Index gauges ionospheric activity on a scale of 0-9; <6 preferred)
Equipment: GNSS Base Receiver Operator: S. Wolters, PLS/CA5; Occupied Base Station
Receiver Make & Model: Trimble R10 with integrated Antenna; Mount: Tripod & Tribrach
GNSS Rover Receiver Operator: S. Wolters, PLS/CA5
Receiver Make & Model: Trimble R12i with integrated Antenna; Mount: Fixed Height Pole
Adjustments: "Starnet-PRO”
Prior to 2019, geodetic grade GNSS receivers collected static satellite signal data for post processing. The
instrumentation was upgraded to an RTK System operating in real-time with an FM radio system in 2019
utilizing the latest technology to deliver increased productivity and precision of point positions. These receivers
incorporate an Inertial Measurement Unit (corrects pole tilt) and track all satellites in all four GNSS
constellations (GPS, GLONASS, Galileo and Beidue). The differences in two independent positions resulting
from two measured vectors are acceptable if on average they fall within 0.03 feet (1 cm) horizontally.
NETWORK ADJUSTMENT & ANALYSIS
Network Adjustment: Minimally constrained adjustments are utilized to develop NAD83 (2007) 2007.00
Epoch, Zone 5 State Plane Coordinates and NAVD88 elevations of the monitoring points. The NAVD88
elevations are determined by combining the measured ellipsoid heights with the Geoid 03 Model. The reference
point occupied by the base station receiver is fixed and the stability verified relative to PVE3 by occupations
(measurements) to other reference points referred to above and PVE3RP all outside the influence of land
movement. See the attached file “PB MOVEMENT DATA POSTING No. 2…. .xlsx” for movements and
coordinates. The adjustment results are listed as differences in the following format example in the Addendums.
Differences in Feet
ID dN dE dZ_
RP05 0.00 0.00 0.00 Fixed
PVE3RP -0.01 -0.02 -0.05 Check
RP02 -0.03 0.00 0.03 Check
Comments: Fixing the base station, the computed differences at the other Reference Points between the
measured and known positions are expected to be insignificant (measurement noise) and therefore confirm the
survey reference frame is stable and successfully recovered from which local land movements are accurately
determined.
ACCURACY STATEMENT
Vector Residuals: The vector residuals are based on a network adjustment of independent observations and are
listed in the Addendums. The horizontal two-dimensional vector residuals and the vertical residuals resulting
from multiple observations on a point are a good indicator of the accuracy of the survey. The horizontal are
expected on average to be less than 0.03 feet and the vertical less than 0.10 feet.
Movement Accuracy: A point is deemed to have moved if, at the 95% level of confidence the horizontal
movement (signal) of a point between two epochs (surveys) is greater than the 95% Error (noise). The accuracy
or uncertainty of the horizontal (2D) movements between two monitoring surveys is estimated to be 0.04 feet at
E-4
McGEE SURVEYING CONSULTING
5290 Overpass Road, Ste#107, Santa Barbara, CA 93111
Page 5 of 7
the 95% Level of Confidence. The estimated vertical uncertainty is about 0.06 to 0.10 feet. Accuracy is
dependent on environmental conditions and obstructions to satellite signals. If a computed movement is less
than the Confidence Level then the movement is statistically indeterminate and has not moved.

Note, the recovery and confirmation of a stable reference frame is essential for assessing the actual movement of
the monitoring points. These differences are within the expected measurement uncertainty, are insignificant, and
confirm the successful recovery of a stable reference frame (coordinate system) to assess movements.
2D Horizontal & Vertical Movements: In the attached “PB MOVEMENT DATA POSTING…” spreadsheet,
the measured land movements are listed for overall and the referenced period. The movements are shown as
azimuths (directions clockwise from north) in degrees, the two-dimensional horizontal movements, and vertical
(elevation) changes for the period in US Survey Feet. The rates of movement for the period are normalized to an
average month of 30.42 days for comparison with previous periods.

Number of Points: 20 Points
Period: M82 to M83 (13 days)
Movements greater than the confidence level: 16
Movement: Average 0.6 feet/month; Maximum of 0.8 feet
Change in Rate of Land Movement (velocity): -34% to +9%; Average -15%.
Note, the values are derived by normalizing the semi-monthly movements to an average month which is less
accurate due to the signal to noise ratio and propagation of the uncertainty compared with observations for a
monthly period.
Accuracy Statement: Vector Residuals based on an analysis of multiple occupations are an indication of the
precision of the survey. Residuals are estimated as follows:
Horizontal (2D): 0.02 feet; Standard Deviation 0.01 feet; Range 0.01 to 0.06 feet.
Vertical Residuals: Absolute Value 0.02 feet; Standard Deviation 0.02 feet; Range -0.05 to +0.07 feet.
The accuracy or uncertainty of the horizontal (2D) movements between two monitoring surveys is estimated to
be 0.04 feet at the 95% Level of Confidence. The estimated vertical uncertainty is about 0.05 to 0.10 feet.
Accuracy is dependent on environmental conditions and obstructions to satellite signals. If a computed
movement is less than the Confidence Level then movement is statistically indeterminate. The confidence level
for a semi-monthly measurement when normalized to a monthly is greater.
