FISCAL IMPACT:

Cost to Date:

The total estimated cost for the Greater Portuguese Bend–Ancient Altamira Landslide Complex (Landslide Complex) from 2022 through June 30, 2027, is projected to reach close to $75 million ($74.8 million). Compared with prior 60-day report, this amount increased to include $1.75 million for the Abalone Cove Sewer Repair Program and $0.9 million in Tax Assessments, even though these costs are presented separately 1 in the budget. This cost is funded through multiple sources, mainly funded from the CIP Fund, General Fund, Metro Funds, ARPA, Gas Tax, Federal Grants, Supervisor Hahn’s Social Program Grant, Los Angeles County Sanitation District No. 2, and Los Angeles Flood Control District.

Fiscal Year (FY) 2025-26 Draft Year-End:

The City is currently closing its financials for FY 2025-26. In accordance with accounting requirements, prior-year transactions may continue to be recorded for up to 60 days after the fiscal year-end, through August 31. Based on draft year-end expenditures, FY 2025– 26 expenditures for the landslide projects are approximately $12.9 million, which is $4.95 million, or 28% below the revised budget of $17.9 million, as summarized in the table below. Of this amount, Staff anticipates approximately $2.3 million in carryover for landslide projects that were started but not completed by June 30, 2026.

As part of year-end closing process, Staff will continue to review and audit transactions in accordance with accounting requirements. Subsequently, CLA, the City’s independent certified public accounting firm, is expected to begin its audit in October. Any material changes will be reported to the City Council.

FY 2026-27 Budget:

Starting July 1, 2026, the FY 2026-27 Adopted Budget includes $10.6 million for landslide-related expenditures, $1.75 million for Abalone Cove Sanitary Sewer Repair Program, and $0.9 million of Tax Assessments to be paid to the Abalone Cove Landslide Abatement District (ACLAD) and Klondike Canyon Landslide Abatement District (KCLAD) for a total of $13.2 million.

EXECUTIVE SUMMARY:

Tonight, the City Council is being asked to receive and file an update on the Landside Complex conditions, activities, and financials. The City Council is also being asked to extend the temporary prohibition of one-, two-, and three-wheeled vehicles on Palos Verdes Drive South, continue the local emergency declaration, and continue the local deenergization emergency declaration for 60 days due to continuing landslide conditions. • Following are key rainfall updates:
o As of September 8, 2026, 15.57 inches of rain have fallen in the 2025-26 rainy season, which is about 114% of average seasonal rainfall. This total includes 0.97 inches, which recently fell on September 5-8, 2026, related to Tropical Storm Marie in the Eastern Pacific Ocean.
• Following are key landslide movement rate updates as of August 4, 2026:
o The average movement rate for all points still moving within the active landslide boundary is approximately 0.99 inches/week, an approximately 9.8% decrease since July 6, 2026 and 25.3% decrease for the approximate three-month period since May 5, 2026. This is the first time since October 2023 that the average horizontal movement velocity of all actively moving GPS monitoring points within the landslide has dropped below 1 inch per week.
o The Landslide Complex is moving about 49% slower than it was about one year ago (August 5, 2025), despite an above-average rainy season. o The Abalone Cove Landslide (ACL) decelerated an average of about 7.7% since July 6, 2026 to an average rate of movement of approximately 1.29 inches/week. o The Portuguese Bend Landslide (PBL) decelerated an average of about 13.9% since July 6, 2026 to an average rate of movement of approximately 0.81 inches/week.
4 o The Altamira Landslide located above or outside the historical ACL and PBL boundaries decelerated an average of about 7.1% since July 6, 2026, to an average rate of movement of approximately 1.22 inches/week. o The Klondike Canyon Landslide (KCL) generally continues to show no measurable horizontal or vertical movement.
• Following are key dewatering program updates:
o The City originally drilled 11 Deep Dewatering Wells (DDWS) in 2024, two of which have been permanently removed from service. The 9 remaining DDWs pumped approximately 17.6 million gallons in July 2026 and 18.7 million gallons in August 2026. As of early September 2026, 6 of the 9 remaining DDWs are operational.

The remaining 3 DDWs have all sheared and are offline pending redrilling. The first redrill is underway. The two remaining redrills will follow in sequence immediately afterward.
• The Abalone Cove Landslide Abatement District (ACLAD) currently has 14 operational wells (a combination of original wells and new DDWs). Approximately

5.7 million gallons of water were pumped in July 2026 and 5.1 million gallons in August 2026.
• The Klondike Canyon Landslide Abatement District (KCLAD) currently has 3 operational wells. Approximately 5.7 million gallons of water were pumped in July 2026 and 5.1 million gallons in August 2026.
• Following are key winterization program updates:
• The City began implementing its FY 2026-27 winterization program on August 20, 2026. Winterization measures include securing canyon liners, replacing sandbags, filling fissures, and drainage improvements (sump pumps, etc.) in areas prone to flooding such as along Palos Verdes Drive South. All work will be completed by October 15, 2026.
• ACLAD began their FY 2026-27 winterization program in August 2026. Measures include drainage improvements for upper Narcissa Drive at Ginger Root Lane, Narcissa Drive at lower Ginger Root Lane, and at the Narcissa Drive curve; and repair of the Kelvin Canyon culvert. All work will be completed by October 15, 2026. • KCLAD began their FY 2026-27 winterization program in August 2026. Measures include replacement of the 48-inch storm drain under Palos Verdes Drive South which was damaged during the 2023-24 storm season. All work will be completed by October 15, 2026.
• Palos Verdes Drive South (PVDS) historical rates of movement at six nearby survey points within the landslide area were compared to current rates of movement.

Although current rates are well below the peak movement rates of July 2024, they are an average of over four times greater than rates before major acceleration (generally considered to be before October 2022).
• Following are key financial updates:
o FY 2026–27 Adopted Budget includes $13.2 million for landslide-related costs, consisting of $10.6 million for landslide expenditures, $1.75 million for the Abalone Cove Sanitary Sewer Repair Program, and $0.9 million for ACLAD and KCLAD tax assessments.
5 o As of August 31, 2026, FY 2026-27 expenditures and commitments totaled approximately $4.7 million, or 35% of the $13.2 million budget. o As of August 31, 2026, preliminary FY 2025-26 year-end expenditures are $12.9 million, which is approximately $4.95 or 28% less than budget of $17.9 million. Of this amount, Staff anticipates approximately $2.3 million in carryover for landslide projects that were started but not completed by June 30, 2026. o The City fully disbursed $3.5 million in loans to ACLAD and KCLAD. Repayment begins in December 2026 under 12-year terms at 2.5% interest. o As of August 31, 2026, ACLAD had fully expended its $1.6 million loan, while KCLAD had spent approximately $1.5 million, or 78%, of its $1.9 million loan. o Payments to the City of $156,954 from ACLAD and $186,932 from KCLAD are scheduled for December 2026. These loan payments are an important revenue source for the CIP Fund as its available balance continues to decline and helps fund ongoing capital and maintenance projects throughout the City that have not been able to be completed due primarily to funding limitations. • Following is a summary of grants related to the Landslide Complex:
o The City is pursuing 8 grants for the voluntary buyout program and mitigation projects in the Landslide Complex, totaling $136,244,490 with a required nonfederal match of $36,900,079 (total grant project amount of $173,144,569). o At this time, the City does not have funds in its budget nor reserves for all the match funds.
o CalOES and FEMA have indicated a willingness to work with the City to identify options on how the matching funds can be reached without reducing the budget for each project.
o The City intends to continue to pursue these grants with the understanding that funds will not be accepted until the City Council formally accepts the terms and funds of each grant at a future meeting.

BACKGROUND:

The Greater Portuguese Bend Landslide Complex, sometimes called the Ancient Altamira Landslide Complex (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) and 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 14, unless extended again this evening.
6 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 ACLAD and KCLAD responsibilities as identified in their respective Plans of Control.

On February 18, 2025, the City Council affirmed only using the $1.6 million City loan to implement ACLAD’s DDW Plan including two monitoring wells and instrumentation that would be installed, maintained, and operated by ACLAD within their jurisdictional boundaries. A sum of $100,000 was also approved to provide ACLAD with professional services (i.e. project management and geologist).

On May 6, 2025, the City Council received a summary of the status of the DDWs 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 due to the diminishing CIP fund balance and the City’s limited ability to complete other capital projects throughout the City. 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 Palos Verdes Drive South (PVDS) and 100% of the cost of Lower Altamira Canyon winterization by ACLAD.

This report will serve as the 60-day standing report on the current conditions of the Landslide Complex, to receive a status update on the City’s preparation for the rainy season in relation to forecasted strong El Niño conditions, to receive a status update on the grants related to the City’s response to the Landslide Complex, and consideration to extend the local state of emergencies and prohibition of one-, two-, and three-wheeled vehicles along PVDS through the Landslide Complex.

DISCUSSION:

1. Greater Portuguese Bend Landslide Complex Update
The City Council is being asked to receive and file an update on the Landslide Complex conditions, activities, and financials.

Geologic Conditions
A summary of the 2022-23 and 2023-24 rainy seasons can be found in the May 7, 2024 staff report at the following link:
https://rpv.granicus.com/MetaViewer.php?view_id=5&clip_id=4522&meta_id=118930 7 A summary of the 2024-25 rainy season can be found in the May 6, 2025 staff report at the following link:
https://rpv.granicus.com/MetaViewer.php?view_id=5&clip_id=4791&meta_id=127446 For the 2025-26 rainy season, 15.57 inches of rain have fallen at Rolling Hills Fire Station 56 near the crest of the Palos Verdes Peninsula as of September 8, 2026 (This total includes 0.97 inches, which recently fell on September 5-8, 2026, related to Tropical Storm Marie in the Eastern Pacific Ocean). This represents about 114% of the annual average for the entire season. About 89% of the season total rain fell in five storm periods:

October 14-15, 2025 (1.19”), November 13-21, 2025 (5.52”), December 23-26, 2025 (3.11”), December 31-January 6, 2026 (1.78”), and February 15-21, 2026 (2.18”). The November and December 2025 storms, which occurred after the November 4, 2025 Global Positioning System (GPS) monitoring and before the January 8, 2026 GPS monitoring, had a measurable impact on the rate of landslide movement, contributing to landslide reacceleration following a prolonged period of deceleration. The landslide complex (except for the KCL which is not moving) accelerated for three months, from November through January but has been decelerating since the February 2026 monitoring readings. For comparison, a similar phenomenon was observed during the much drier 2024-25 rainy season; however, the landslide acceleration only lasted for one month and appeared to be in response to a single 9-day storm period from February 5- 14, 2025, when 3.25 inches of rain fell. The rainfall and land movement data will continue to be evaluated in an effort to understand the relationships between the timing, severity and quantity of seasonal rainfall and changes in land movement velocity. This information may provide further insights into the effectiveness of winterization measures and the impacts on land movement notwithstanding the current deep dewatering systems operated by the City, ACLAD and KCLAD.

Recent GPS survey data published by McGee Surveying Consulting for the approximately “monthly” monitoring period ending August 4, 2026 were reviewed and analyzed (Attachment E). Figure 1 presents scaled displacement rates (i.e., movement velocities), movement vectors, and contours (aka “heat maps”) of displacement rates for the August 4, 2026 monitoring period. (Attachment D)

*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 monitoring period ending August 4, 2026:
o The average movement rate for all points still moving within the active landslide boundary as of August 4, 2026 is 0.99 inches/week, a 9.8% decrease since July 7, 2026. To provide another perspective, the Landslide Complex is moving 49% 10 slower than it was one year ago (July 1, 2025) despite an above-average rainy season.
o The ACL movement, within its historical boundary, has decelerated an average of about 7.7% since July 7, 2026. The average rate of movement for these points was approximately 1.29 inches/week in the most recent monitoring period from July 7, 2026 through August 4, 2026. The ACL has decelerated about 86% since the City’s deep dewatering program commenced in mid-September 2024 (using September 4, 2024 monitoring rates as a benchmark). The ACL has also decelerated about 70% since ACLAD’s deep dewatering well program commenced in the spring of 2025 (using March 9, 2025 monitoring rates as a benchmark), despite a three-month period of acceleration from November 2025- January 2026 which was in response to atypical high early season rainfall. The fastest moving areas are the upper portion of the ACL (i.e., monitoring point AB24 within the historical Abalone Cove Landslide boundary) and the middle ACL (i.e., monitoring point AB60), both of which are moving at approximately 1.44 inches/week. As can be seen in Figure 2, despite the 3-month period when movement accelerated, the ACL continues to exhibit the highest reduction in landslide velocity between March 9, 2025 and August 4, 2026, which is a direct effect of the deep dewatering program implemented by ACLAD. o The PBL, within its historical boundary, has decelerated about 13.9% since July 7, 2026. The average rate of movement was approximately 0.81 inches/week in the most recent monitoring period from July 7, 2026 through August 4, 2026. As of November 4, 2025, the PBL movement had decelerated an average of 88.3% since the deep dewatering (DDW) program commenced in mid-September 2024; however, unusually high early-season rainfall and normal mid-season rainfall contributed to a 3-month period of acceleration from November 4, 2025 through February 3, 2026. The PBL movement deceleration relative to movement rate just prior to the DDW program implementation is now 92%. The area of the PBL within its historical boundary that is moving less than 1 inch per week is approximately 74%. Staff will continue to track and report this metric with future readings. o In the staff report for the August 4, 2026 City Council meeting, staff noted that there had been no measurable movement of the KCL since mid-October 2024. An exception to this was identified with regard to GPS Monitoring Point KC30 which is located along Yacht Harbor Drive very close to the KCL/PBL boundary. KC30 moved 0.07 ft. between the June 2, 2026 and July 7, 2026 monitoring period. This movement was slightly above instrument precision (stated as 0.04 ft. at the 95% confidence level) and also in a direction consistent with past historical movements.

The City Geologist postulated that this movement might be a manifestation of the PBL “pushing” on the KCL, a phenomenon that occurred historically prior to the major, deeper movements in 2023 and 2024. In the July 7, 2026 to August 4, 2026 monitoring period, KC30 moved horizontally 0.01 ft. on an upslope vector, which is well below instrument precision and is considered survey “noise” rather a signal of movement. It also moved 0.09 ft. vertically, which is very close to instrument precision limits for vertical movement. The City Geologist will continue evaluating 11 this area; however, an additional month of movement data is needed to assess longer-term patterns.
o Analyses of vertical survey data of the KCL concluded that no vertical movement of the GPS monuments within the KCL has occurred since the survey period ending October 8, 2024, within the instrument and monitoring method precision limits which are typically 0.10 ft. for vertical movement. o The movement rate of the Altamira Landslide Complex GPS monitoring points outside of the historical boundaries of the ACL and PBL has, on average, decelerated about 7.1% in the monitoring period from July 7, 2026 through August 4, 2026. The average rate of movement for these points was approximately 1.22 inches/week as of August 4,2026. The Altamira Landslide Complex points have decelerated an average of about 87% since the deep dewatering program commenced in mid-September 2024.
o 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.
o 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 the 2024-2025 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 the hypothesis that the Altamira Complex and the landslide(s) further north-northeast in Rolling Hills, are not directly structurally connected.
o There continues to be no measurable movement of GPS points located outside of the mapped 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.

Open Space, Palos Verdes Nature Preserve, Trails, and Beach Conditions Current trail and beach closures continue to exist within the Portuguese Bend, Filiorum, and Abalone Cove Reserves. Approximately 12.5 miles of trails within these Reserves remain closed, as well as the open space area around the Archery Range, due to landslide-related damage and/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. The City Manager temporarily closed these areas in close coordination with the City Geologist, L.A. County Fire Department and Lifeguards, California Coastal Commission, and Public Safety agencies. The City continues to monitor these areas closely with managing partners and subject experts for opportunities to reopen.

At the September 16, 2025 City Council meeting, members of the Portuguese Bend Community expressed the significant detrimental impact to their community of having so 12 many trails closed adjacent to their community. They spoke of the specific impact to equestrians and voiced their need for trail access. They additionally expressed their desire to use the trails located within the 96-acre Wildlife Corridor acquired in 2022.

Detailed information on these topics was provided in the “Additional Information” section of the November 4, 2025 City Council Staff Report (Attachment G).

The City was recently awarded a $500,000 competitive grant from the L.A. County Regional Park and Open Space District to explore the design of a multiuse trail connecting the Three Sisters and Filiorum Reserves. Constructing this trail would significantly increase trails available to the Portuguese Bend equestrian community. The planning process for this trail has begun and involves coordination with the U.S. Fish and Wildlife Service and Palos Verdes Peninsula Land Conservancy, because this trail will be located in the Preserve and may have potential impacts to biological resources. Once designed, the City will seek funding opportunities to build the trail which will likely take more than two years.

Deep Dewatering Well Program Status
The DDW component of the emergency stabilization activities is complete. The August 19, 2025 City Council staff report shows the locations of the DDWs and monitoring wells (Attachment H). Table 2 on the following page provides the current DDW program statistics. Following are key observations on the current status of DDW operations:
• The City originally drilled 11 DDWS in 2024, two of which have been permanently removed from service due to low production levels. The 9 remaining DDWs pumped approximately 17.6 million gallons in July 2026 and 18.7 million gallons in August 2026. Since the start of the DDW program in September 2024, approximately 561 million gallons, or 1,719 acre-feet of water have been extracted. • As of early September 2026, 6 of the 9 remaining DDWs are operational. The remaining 3 DDWs have all sheared and are offline, pending redrilling. The first redrill is underway. The two remaining redrills will follow in sequence immediately afterward.

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 City Council Staff Report (Attachment H).

Chart 1 on the following page shows water pressures from the piezometers installed under the deep slip plane and Chart 2, on the 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. [continued on next page]
14 Chart 1: PBL Deep Slip Plane Water Pressure
Chart 2: PBL Mid-Deep Slip Plane Water Pressure
15 For those piezometers near the DDWs in 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 (SeptOct 2024). The surviving piezometer, P-2, continued to show a relatively constant decrease to more of a somewhat current steady state pressure drop over time at different levels, which correlated to reduced surface movement in nearby GPS survey points. Then, in the July to August 2025 timeframe, there was an increase in pressure which correlated to reduced operation of DDWs for re-drilling and other maintenance.

Once the DDWs were back to regular operation, there was a continued reduction in pressure. However, from November 2025 to March 2026, there was a slight increase in pressure in both the deep and mid-deep piezometers, which may be reflective of the early season rainfall events and in combination of periodic shut down and re-drilling of DDWs in the area. Dating back to October 2025, pore pressures are on an overall steady state trend with time; however, there was a slight increase between March and June 2026 in the deep piezometer as two wells had reduced production and sheared. Now that wells are back on-line, pore pressures are continuing to decrease again on a slight gradient through Auguust 2026.

The piezometers far away from DDWs (E-2-2 and E-2-5) show slight decreases to relatively constant pressures over the last year. In general, E-2-2 and E-2- 5 do not show any marked increase in pressure through time that can be correlated to the winter rains. However, these piezometers do seem to have nearly constant or very gradual drops in pressure over time, which may indicate that the pumping wells at the toe of the slide, even though not in close proximity, do have a regional effect to prevent buildup of pressures in this portion of the landslide. The deep piezometer sensor in E-2-2 has now malfunctioned, most likely do to shearing above that level in the borehole casing.

ACLAD Update
ACLAD Dewatering Well Program Status
The following is a summary status of ACLAD’s dewatering activities for September 2026.

The locations of ACLAD dewatering wells can be found in the August 19, 2025 City Council Staff Report (Attachment H).
• ACLAD currently has 14 operational wells (a combination of original wells and new DDWs).
• Approximately 5.7 million gallons of water were pumped in July 2026 and 5.1 million gallons in August 2026.
• Groundwater elevations have dropped from an average of 85' to 148' over the past year since the DDWs were installed
• Dewatering well pumping rates and water levels are generally consistent with prior months. Well readings are uploaded to the ACLAD website at ACLAD.ca.gov 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 City Council Staff Report (Attachment H). The piezometers 16 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]
17 Chart 4: ACLAD Mid-Deep Slip Plane Water Pressure
The plots for those piezometers near the DDWs in the ACL (Alta 8 and Alta 9), 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. Alta 8 shows a continuous decrease in pressure within the deep piezometer and the mid-deep piezometer until March 2026; at which point there is a slight increase. This could be due to breaks within the casing of the piezometer creating interconnectivity of pressure, making pressure from one piezometer additive to the pressure of the next piezometer. No obvious change in pressures were noted within the last three months. Alta 9 is no longer functional as it has been sheared.

Chart 5 on the following page provides a comparison of piezometric surfaces in monitoring well Alta-8 with average movement velocities of the 12 GPS monitoring points closest to Alta-8.
• An abrupt decline in pressure for the middle piezometer in Alta-8 occurred around May 1, 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 pressure for the shallow piezometer, and decrease in movement velocity, particularly notable around the middle of March, 18 2025 but then significantly dropping around the beginning of July, 2025 when DDW 29 came online. DDW 29 went offline on October 10, 2025 due to a generator issue, and there is an immediate response seen, with rising pressure for both the shallow and middle piezometers in Alta 8, until the pumping was restarted on October 22, 2025, after which piezometric levels began to fall again. This is a clear indication that DDW 29 is reducing groundwater levels (expressed as pressure) in multiple aquifers that do not appear to be hydraulically connected, but are both penetrated by the monitoring well as well as the dewatering well. This has slowed the movement of the ACL and upper Altamira Landslide by about 70% since March, 2025.
o Based upon review of Chart 5, the piezometric surfaces for all three piezometers show generally declining water pressures at the commencement of the ACLAD DDW program and an accompanying significant decline in land movement rate until November 2025. After November 2025, the shallowest piezometer has shown a continuing pressure decline while the middle and middle-deep piezometers have shown varying response to the five main rainstorms of the 2025-26 season to date, including slight uptrends in pressure since March 2026 which could be related to additive pressure from one piezometer to the next due to breaking of the casing. The middle and middle-deep piezometers appear to have reached a steady state since the middle of May 2026 (i.e., no further pressure reduction). The red line on the graph also illustrates the threemonth period of movement acceleration (Nov 2025 through Jan 2026) followed by recent 6-month deceleration through August 4, 2026, relative to piezometric levels. This would appear to indicate that the current land movement is more tied to pressures from the shallow piezometer, which continue to decline.
o The City’s consultants continue to review these important data to evaluate dewatering effectiveness and pumping program refinements. [continued on next page]

26 2. City’s preparation for the rainy season in relation to forecasted strong El Niño conditions
City Emergency Winterization Measures Status
Staff, in consultation with the project engineering geologist and City geologist, are progressing winterization measures with an approach similar to last year, and ahead of the 2026-2027 rainy season and forecasted powerful El Niño conditions. This work is being undertaken to minimize runoff from recharging the groundwater table at the most vulnerable points. An update of ongoing and completed City-led winterization work is described in Table No. 6 below, with new improvements noted in bold when compared to what was completed last rainy season.

Anticipated Completion: Early October
Staff are mobilizing a contractor to install additional passive drainage measures for floodprone areas along Palos Verdes Drive South within the Landslide Complex. The work is anticipated to be completed by early October.
27 Status of City’s Preparations for the Rainy Season
The National Oceanic and Atmospheric Administration (NOAA) forecasts a greater than 90% chance that the ongoing El Niño conditions will grow into a very strong “super” event during the fall and winter of 2026-27. Staff have proactively responded by implementing protective measures across the landslide. The following details the scope of these protective measures, all of which are scheduled to be completed by or before the end of September 2026:
• Winterization Measures
o Staff mobilized contractors several weeks earlier than the two previous fiscal years to carry out maintenance and improvements to previously winterized areas.
o Sections of pond liner systems are being welded together at the most critical areas to withstand land movement, rockfall, windy conditions, and further reduce permeability when conveying surface water.
o Additional debris and erosion protection measures are being implemented at winterized canyons.
• Deep Dewatering Wells
o Electrical cabinets and appurtenant equipment serving the DDWs that are located close to the coastline will be elevated where possible to withstand elevated swell conditions.
o Enclosures will be installed over wells to withstand elevated rainfall and surf conditions.
o Access to the DDWs will be improved to provide adequate access for operations, monitoring, maintenance and drilling crews. • Palos Verdes Drive South (PVDS)
o Additional passive drainage measures are being developed and installed to reduce the city’s reliance on pumping operations to minimize necessary road closures
o Staff have standardized last year’s storm monitoring and response program, including lines of communication, assignment of staffing (management and on-site crews), traffic control, and public notification protocols.
o Measures will be implemented (i.e. reinforced chains, surveillance cameras, etc.) to harden generators used to power sump pumps along PVDS.

4. Bicycle, Motorcycle, Unicycle and Other Similar Wheeled Vehicle Prohibition The City Council is being asked to extend the existing resolution prohibiting one-, twoand three-wheeled vehicles on PVDS for an additional 60 days (Attachment A).

PVDS within the Landslide Complex has experienced ongoing and significant land subsidence and surface deformation since the acceleration of landslide movement, resulting in persistent and severe bumps, dips, elevation changes, cracking, and uneven patch transitions. Despite repeated maintenance efforts, roadway conditions remain unstable and continue to evolve, indicating that the underlying geotechnical movement is ongoing and is anticipated to persist for the near term. 29 These conditions exceed what motorcyclists, bicyclists, unicyclists, scooters, e-bikes and the like; traveling at lawful speeds can reasonably anticipate and/or navigate. Of particular concern is the disproportionate safety risk posed to these modes of transportation, which have limited tolerance for sudden grade changes, narrow contact patches, and pavement cracking. Additionally, there is reduced ability for these modes of transportation to recover from surface anomalies.

In order to quantitatively demonstrate the movement along PVDS, historical rates of movement at six survey point locations are included below. Figure 3 below shows the location of six survey points along PVDS between Peppertree Drive and the eastern edge of the Landslide Complex. Table 8 below shows a comparison of historic movement rates for these six survey points as reported by City consultants.

*Month of emergency declaration
**Month of peak movement rate
30 The monthly movement rates in Table 8 show that current rates are well below the peak movement rates of July 2024; however, the rates are an average of over four times greater than the rates before major acceleration (generally considered to be before October 2022).

Based on professional engineering judgment of City staff, the PVDS roadway segment within the Landslide Complex is best characterized as continuing to deform and is not yet stable. In this condition, even in the absence of documented crashes, it is advised that these modes of transportation continue to be precluded from accessing designated portions of PVDS. The lack of stability also limits the effectiveness of short-term repairs.

The City Council has extended the local prohibition on multiple occasions within the 60- day window and it remains in effect until October 3, 2026, 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 November 14, 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 November 4, 2026.

5. 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.

The City Council has extended the local emergency on multiple occasions within the 60- day window, and it remains in effect until October 3, 2026, 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 November 14, 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 November 4, 2026.

6. 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. 31 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.

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.

Hydrology & Hydraulics Study Update
On October 13, 2025, the City’s consultant, Geosyntec Consultants, Inc. (Geosyntec), started work on a comprehensive hydrology and hydraulics study of the Landslide Complex.

The general scope of the study is the following:
• Develop a Hydrology and Hydraulics (H&H) model for the entire Landslide Complex watershed (including the City of Rolling Hills) 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.

Geosyntec has completed a draft preliminary watershed demarcation, including assessing contributing areas upstream of the Landslide Complex, and processing historical rainfall data for inclusion in the study model. Draft concept plans for alternatives 32 to reduce stormwater infiltration have been prepared and are undergoing quality control review. Subsurface data collection is complete, and the data is being synthesized into exhibits displaying sub-surface features.

A draft of the Hydrology and Hydraulics Study is anticipated to be completed by late fall, followed by its presentation by Staff to the City Council.

Disaster Cost Recovery Applications Update (FEMA and CalOES) Obligated Funds from FEMA ($574,335 as of January 2026):

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 expedite the payments. Subsequently on October 10, 2025, FEMA notified the City that approximately $574,400 has been obligated and forwarded to CalOES for the reimbursement process.

On January 5, 2026, CalOES sent the City a Notification of Obligation and Payment for Public Assistance and CDAA Grants Program FEMA-4769. On January 26, 2026, the City received the first payment of $447,044, as shown below and the amount of $574,400 has been appropriated by the City Council on February 3, 2026. Staff continue to work with CalOES to receive reimbursement for the remaining balance of the grant.

A summary of obligated funds from FEMA is provided in Table 9 on the following page. [continued on next page]
33 Table 9 - Obligated Funds from FEMA – Public Assistance from Winter Storms (Jan. 31, 2024 - Feb. 9, 2024)
Projects Denied from FEMA ($37,775,258 as of January 2026) 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 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 eighth 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.

34 Projects Denied from FEMA ($37,775,258 as of January 2026) 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. • Applicant did not demonstrate there was an immediate threat that required emergency protective measures.
• Several facilities are ineligible for public assistance funding. • 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. • Facility 1 (PVDS between Schooner Dr and Seacove Dr), Facilities 2 and 3 (two locations on Hawthorne Blvd.) are under the authority of another Federal agency.

On December 1, 2025, the City filed an appeal of District No. 9 Administrator Mr. Robert Fenton’s denial to FEMA Headquarters. A copy of the appeal is available on the City website at the following link:
https://www.rpvca.gov/DocumentCenter/View/24009/December-1-2025-FEMA-AppealLetter-PDF On January 16, 2026, Cal OES responded to the City’s appeal letters by forwarding a recommendation to FEMA indicating that it does not support the City’s appeal, following its review and analysis under applicable laws and regulations. FEMA has 120 days to render a final decision (with no direct consequences if more time is taken).

36 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 received similar notifications that their appeals were denied by District No. 9 Administrator Mr. Bob Fenton (who is currently serving as the Interim FEMA Administrator). ACLAD and KCLAD collaborated with the City and filed a second and final appeal to FEMA Headquarters which are pending review similar to the City.

CONCLUSION:

The City’s dewatering well program is currently operating nine dewatering wells and pumped at a rate of approximately 17.6 million gallons in July 2026 and 18.7 million gallons in August 2026. ACLAD has 14 operational wells and pumped at a rate of 5.7 million gallons of water in July 2026 and 5.1 million gallons in August 2026. KCLAD has three operational wells and pumped at a rate of approximately 10 million gallons of water in July 2026 and 6 million gallons in June 2026.

The City’s winterization program is currently underway and implements improvements beyond what was accomplished in FY 2025-26. Winterization measures include securing canyon liners, replacing sandbags, filling fissures, and drainage improvements in areas prone to flooding such as along Palos Verdes Drive South. ACLAD is also implementing its winterization program including drainage measures at multiple points on Narcissa Drive and repairs to the culvert in the Kelvin Canyon area. KCLAD’s winterization measures are focused on repairs to the culvert under Palos Verdes Drive South at its intersection with Klondike Canyon. All winterization work done by the City, ACLAD, and KCLAD will be completed by October 15, 2026.

As of August 4, 2026, the Landslide Complex continues to decelerate following the threemonth period of acceleration from November 2025 to January 2026 to an average rate of movement of 0.99 inches per week, which is a decrease of 9.8% since July 6, 2026. More specifically, the ACL decelerated an average of about 7.7% to an average rate of approximately 1.29 inches/week; the PBL decelerated an average of about 13.9% to an average rate of approximately 0.81 inches/week; and the KCL generally continues to show no measurable movement.

The rates of movement at six survey points near PVDS within the landslide are an average of over four times greater than rates before October 2022.

As of August 31, 2026, preliminary FY 2025–26 year-end landslide expenditures totaled approximately $12.9 million, or $4.95 million (28%) below the $17.9 million budget, before carryover. For FY 2026–27, the Adopted Budget includes $13.2 million for landsliderelated costs, of which approximately $4.7 million, or 35%, was spent or committed.

Staff recommend extending the local state of emergency, the de-energization emergency, and the temporary prohibition of one-, two- and three-wheeled vehicles along PVDS through the Landslide Complex.
37 ALTERNATIVES:

In addition to Staff recommendation, the following alternative action is 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-, two- or three-wheeled vehicles on PVDS and allow one-, two- and three-wheeled to begin using PVDS again.

3. Do not adopt one, or both, of the resolutions continuing the local emergency declarations.

TEMPORARY PROHIBITION ON TRAVEL BY

UNICYCLES, BICYCLES, MOTORCYCLES, AND

OTHER ONE-, TWO- OR THREE-WHEELED

VEHICLES ON PALOS VERDES DRIVE SOUTH

WITHIN THE LANDSLIDE COMPLEX DUE TO

CONTINUED ROADWAY CONDITIONS
WHEREAS, the Greater Portuguese Bend Landslide Complex (the Landslide Complex) encompasses four historically active landslide areas in the City: the Portuguese Bend Landslide (“PBL”), the Abalone Cove Landslide (“ACL”), the Klondike Canyon Landslide (“KCL”), and the Beach Club Landslide (“BCL”). It also includes the Flying Triangle Landslide (“FTL”) in the City of Rolling Hills as mapped by various agencies (i.e., U.S. Geological Survey, California Geological Survey) and other researchers; and
WHEREAS, following the 2022-23 rainy season, the Landslide Complex’s movement has accelerated exponentially. Therefore, on October 3, 2023, the City Council of the City of Rancho Palos Verdes adopted Resolution No. 2023-047 based on its authority pursuant to Section 8610 et seq. and Section 8630 et seq. of the Government Code, and Chapter 2.23 of the Rancho Palos Verdes Municipal Code, declaring a state of local emergency for the Landslide Complex based on the accelerated movement of the land. The declaration of emergency has been renewed as required by law and currently applies; and
WHEREAS, following the City Council’s declaration of a local emergency, the City experienced another record-setting rainy season during the winter of 2023- 24; and
WHEREAS, since the City Council’s declaration of a local emergency, the City Geologist, Mike Phipps of Cotton, Shires, and Associates, Inc. (“CSA”), has been regularly conducting field mapping throughout the Landslide Complex, observing conditions at various locations, and reviewing survey and rainfall data; and
WHEREAS, the City Geologist most recently reported to the City Council on May 7, 2024, in summary, that the Landslide Complex continues moving at unprecedented rates, predominantly in response to the two consecutive seasons of significantly above average rainfall; and
WHEREAS, the City Geologist stated that land movement continued to manifest at the ground surface in the form of landslide scarps, fissures, grabens/sinkholes, tensional cracking, shear zones and thrust features; and that due to the continued acceleration, the ground movement features have continued to enlarge, expand, widen, or grow depending on the type of feature and location, A-1

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, Rancho Palos Verdes Municipal Code 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 one-, two-, or three-wheeled vehicles such as bicycles and motorcycles; and WHEREAS, the City Council finds that the safety of bicycle, motorcycle and other one-, two-, or three-wheeled riders is a compelling interest; and A-2
Resolution No. 2026-__

Page 3 of 4 ends

01203.0023 2172377.1
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, motorcycles and other similar vehicles 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, on August 4, 2026, the City Council identified the safety of three-wheeled riders to be a compelling interest and further approved a motion to include three-wheeled vehicles in this prohibition.

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.
