What the map shows: lines from the City of Rancho Palos Verdes's public GIS data, retrieved Oct. 11, 2026: the 2025 Greater Portuguese Bend Landslide Complex boundary (Ordinance 692) and the Abalone Cove and Klondike Canyon abatement districts. Markers show landmarks and the peninsula's other slides, which are separate from the complex.
What the arrows show: how far each of the City's GPS survey points moved between Sept. 3 and Oct. 6, 2026, the newest full survey the City has posted (the surveyor's point-by-point flags in the City's spreadsheet mark 53 of the 102 points as moved, though the surveyor's written report counts 55; the fastest, AB59, about 1.48 inches per week). The City's Oct. 6 contour map draws arrows for the same 53 points. The written report (Addendum No. 17) counts 55 moved and 47 not moved; the City's posted documents do not explain the difference. The City's contour map labels both AB59 and CR54 at 1.48 inches per week. Each arrow points the way its point moved; bigger, redder arrows moved faster. A small ring means the City's surveyor detected no horizontal movement at the 95% confidence level. The surveyor puts the uncertainty of movement between two surveys at about 0.04 ft and makes the call point by point, so the City's contour map can still print small apparent rates for a few ringed points. The feet-per-month rates, directions, % changes and no-movement calls are the surveyor's, as published in the City's spreadsheet; inches per week are calculated by PVLandslide.com from the surveyor's distances, the way the City's contour maps do it, so they can differ from those maps by 0.01. These are survey monuments, not houses or parcels, and the City posts each survey a few weeks after it is done, so the ground may have moved differently since. As of Oct. 29, 2026, the City had published area averages for this survey (on Oct. 28, 2026); they are in Current Movement by Area below. Source: City of Rancho Palos Verdes, Landslide Surveys and Mapping (the GPS survey data spreadsheet and report by McGee Surveying Consulting; contour maps by Cotton, Shires and Associates). Every point is in the table below the movement rates.
What the red line is: a regulation boundary, not an outline of moving ground. The City's landslide-area development rules (Municipal Code Chapter 15.20, including Ordinance 692's ban on new homes and additions) apply inside it; where it crosses a parcel, only the part inside is regulated. The City's 2025 ordinance puts the actively moving area at about 715 acres within the mapped ancient complex (about 700 acres as of March 2024), so not all land inside the line is moving. Along part of its eastern edge the line follows the Rancho Palos Verdes city limit with Rolling Hills, so it stops at the city limit and does not cover the Rolling Hills parts of slide areas such as the Flying Triangle, which are tracked separately. The district lines show where the two abatement districts work; they are not slide outlines. For how fast the ground is moving, see Current Movement by Area below and the City's survey maps.
About this map: Boundaries from the City of Rancho Palos Verdes GIS service Portuguese_Bend_Landslide_Complex (layers “Greater Portuguese Bend Landslide Complex (2025)”, “Abalone Cove Landslide Abatement District” and “Klondike Canyon Landslide Abatement District”), retrieved Oct. 11, 2026; the City's records for the service were last modified Oct. 20, 2025. The complex layer matches the map adopted as Exhibit A of Ordinance 692 (PDF, 34 MB; map on page 24), adopted Aug. 19, 2025 and in effect since Sept. 18, 2025; the ordinance lets the Council revise the map. Coordinates are rounded to six decimal places, which moves points by less than 10 cm; that is not the accuracy of the City's line. No points were removed except duplicates created by rounding. The City's GIS disclaimer says its map data is informational, is provided as is, is not survey-grade and “has not been prepared for legal, engineering, or surveying purposes.” Marker positions were compiled by PVLandslide.com from USGS place names, the California Geological Survey landslide inventory, City street data, Wikidata, Wikipedia and OpenStreetMap (© OpenStreetMap contributors); markers listed as approximate show a general area, not a property. Background map: map services and data available from U.S. Geological Survey, National Geospatial Program (The National Map). Aerial imagery may not show current conditions, and the City's GIS disclaimer warns that in the Portuguese Bend landslide zones, parcel lines and imagery may not line up because of land movement, so a house in the imagery may appear on the wrong side of a line. That is one more reason this map can't settle where a property falls. Mapping software: Leaflet 1.9.4 (BSD-2-Clause license), hosted on this site. Not an official City map.

Everything on the Map, as a List
The same information as the map, for reading without it. “Precise” markers sit on a named point (a USGS place name, an address or a landmark); “approximate” markers show a general area. Inside or outside refers to the marker point and the City's 2025 line, not to whole neighborhoods or to individual properties.

|---|---|---|---|---|
| Solid red line | Greater Portuguese Bend Landslide Complex: City regulation boundary (2025) | The boundary the City adopted with Ordinance 692 in 2025 (Exhibit A). The City's landslide-area development rules in Municipal Code Chapter 15.20, including the ban on new homes and additions, apply inside it; where the line crosses a parcel, only the part inside is regulated. It is a regulation boundary, not an outline of moving ground: the City's 2025 ordinance puts the actively moving area at about 715 acres within the mapped ancient complex, so not all land inside the line is moving. | This is the line the other entries are compared with.

Current Movement by Area (first four rows: City summary of the early-October 2026 survey, reported Oct. 28; other rows dated in the table)
| Area | Rate | Trend | Notes |
|---|---|---|---|
| Active complex overall | 1.05 in/week average | ▲ 7.6% since early August (staff report: ▼ 3.9% Aug. 4–Sept. 3, then ▲ 11.9% Sept. 3–Oct. 6); about 30% slower than a year earlier | Average across areas still moving inside the active boundary. The City's geologist attributes the increase largely to erosion at the landslide's toe from wave action during an unusually active southeast Pacific hurricane season |
| Portuguese Bend Landslide | 0.88 in/week | ▲ 14.8% from September to October, after ▼ 3.6% from August to September; 91% slower than just before the wells were installed (Sept. 2024; staff report) | Largest slide |
| Abalone Cove Landslide | 1.36 in/week | ▲ 16.7% from September to October, after ▼ 9.5% from August to September; about 85% slower than in early September 2024 (staff report) | Fastest-moving remaining area; ACLAD wells plus new city wells. The staff report says its fastest part is now the toe, about 1.5 in/week (point AB04, labeled 1.46 on the City's contour map), which it attributes to wave erosion |
| Klondike Canyon Landslide | No measurable movement | — generally none in recent surveys | KCLAD wells and drainage; beneath the Seaview area's edge |
| Altamira points outside the Abalone Cove and Portuguese Bend boundaries | About 1.22 in/week (staff report for the Nov. 4, 2026 meeting) | ▲ 8.4% from September to October, after ▼ 7.2% from August to September (▲ about 0.5% since early August); about 87% slower than when the City's wells began (Sept. 2024) | Called "Upper Altamira" in the staff report's Table 1; the City's Oct. 28, 2026 summary does not mention it |
| Seaview | No measurable movement at City GPS points in the Seaview Tract (staff report for the Nov. 4, 2026 meeting); none reported by SoCalGas (May 2025) | — none since about Feb. 2025, per SoCalGas; the staff report says no Seaview sewer work is under way because there has been no detectable land movement for many months | Homes that have taken the required steps may request gas service from SoCalGas (staff report for the Nov. 4, 2026 meeting) |
| Portuguese Bend Beach Club | No measurable movement reported (latest report: SoCalGas, May 2025) | — none since about Feb. 2025, per that report; the City's Oct. 28, 2026 summary does not mention it | SoCalGas said in May 2025 that movement had drastically slowed since October 2024 |
| City of Rolling Hills (affected areas) | ≤ 0.1 in/week for the City of Rolling Hills (SoCalGas, May 2025; the release does not name specific slide areas) | — minimal, per SoCalGas (May 2025); the City's Oct. 28, 2026 summary does not mention it | Separate slide areas in the neighboring city (the Flying Triangle and the Cinchring Road and Quail Ridge Road areas). The City's Sept. 15, 2026 staff report says its survey data continue to support the hypothesis that these are not directly structurally connected to the complex. See Rolling Hills land movement updates |
The first four rows are the City's summary of its early-October 2026 survey (Sept. 3 to Oct. 6, 2026), reported Oct. 28, 2026; the step-by-step complex-wide changes, the 91% and 85% comparisons and the Abalone Cove toe detail are from the staff report for the Nov. 4 meeting, which also gives the Altamira row. The City gave the August-to-September changes only as percentages and, as of Nov. 5, 2026, had not published September per-area rates. Update Oct. 29, 2026: these rows previously showed the City's early-August figures (our Sept. 9 entry); our earlier note that, as of Oct. 23, we had found no newer per-area rates and no October survey is superseded. Seaview and Beach Club: on January 17, 2025 the City reported no new movement in either neighborhood over the previous three months, and in May 2025 SoCalGas reported no measurable movement there since February 2025. The Rolling Hills figure is also from SoCalGas's May 2025 release.

Movement at each City GPS point, survey M99, Sept. 3 to Oct. 6, 2026
From the City's GPS survey spreadsheet (McGee Surveying Consulting), fastest first. Inches per week = distance moved × 12 × 7 ÷ days in the period; feet per month is the surveyor's own figure; the change compares each point's rate with the previous survey period ("not given" where the surveyor left it blank). "Where" places each point against the City's map lines, which are approximate. Points with no movement detected at the 95% confidence level are listed last. Shown on the map above as arrows and rings.

For perspective: the City says movement peaked at nearly 1 foot per week in summer 2024, and in its July 2024 survey the Portuguese Bend Landslide averaged about 11 inches per week (City update, Aug. 26, 2026; staff report, Sept. 15, 2026). In fall 2024 (Sept. 18 to Oct. 17), NASA radar measured up to ~4 inches per week in residential areas. Rates are updated as new survey data is released; see Latest Updates.
On the ground: even where rates are low, the terrain itself is altered — roughly 16 miles of trails in the Portuguese Bend Reserve are damaged, with dozens closed and full restoration considered unlikely. Check the City's trail conditions page before hiking, and treat ground near fissures as unstable even when it looks solid. The City closed the whole Palos Verdes Nature Preserve on Sunday, Nov. 1, 2026, after 0.35 inch of rain overnight, and reopened the trails the next day after inspections (City weekly report No. 26-44, Nov. 5, 2026, a large PDF, p. 43). When we checked on Nov. 5, 2026, the trail page said "Palos Verdes Nature Preserve is Open" and again listed its standing closures; the City says the Preserve may close again after significant rain.
Schematic: The Four Slides Inside the Complex
The City's official map layers draw the complex as one boundary and don't separate the slides inside it. This schematic sketches them for orientation: the four active slides (Portuguese Bend, Abalone Cove, Klondike Canyon and Beach Club), the ancient boundary, dewatering wells, the 2024 utility-shutoff neighborhoods (which are also where the buyout homes are located), and key landmarks.

About this schematic: Schematic and approximate — drawn for orientation, not for parcel- or survey-level decisions. Its dashed outline sketches the ancient complex; it is not the City's 2025 regulation boundary, which the interactive map above draws from City data. Slide outlines generalize California Geological Survey mapping (2007 boundaries; the active area expanded beyond them during 2024). Well positions indicate general locations of the City's deep dewatering wells at the Portuguese Bend toe and district wells, not exact coordinates. For authoritative maps, see the City's GPS survey maps, the City's Landslide Area Development Regulations boundary map (PDF, 3.8 MB) for which parcels fall under Ordinance 692, and NASA/JPL radar imagery.
Which homes are being bought? Buyout acquisition tracker
The City, FEMA and Cal OES have not published the addresses of the homes selected for the Voluntary Property Buyout Program. What is public, as of the City's Oct. 14, 2026 announcement: 85 applications were received; 22 homes were selected in Round 1 and 5 more in Round 2, 27 in all; the City has been formally awarded over $54 million in FEMA grants for those two rounds; and a Round 3 application ($19M, roughly 8 more homes) remains waitlisted. The City says it will buy the homes in groups of a few at a time, expected to start in the coming months, and that acquiring all 27 and demolishing the homes will likely take a few years; acquired land is to be deed-restricted as permanent open space. No purchases under the buyout program had been reported as of Nov. 6, 2026 (City buyout page; City weekly report, Nov. 5, 2026). The City's presentation at the Nov. 4 Council meeting says an orientation meeting for the pre-selected Round 1 properties was held Oct. 29, 2026. In the City's RPVtv video update posted Nov. 5, 2026, City Manager Ara Mihranian says the Council approved nearly $56 million in federal grant funding on Nov. 4: more than $54 million for the voluntary buyout of 27 red- and yellow-tagged properties and $1.9 million for permanent power to the deep dewatering wells. Next check: the City's buyout page, for the first purchases. Neither the City's announcement nor FEMA's Sept. 29, 2026 release about the funding names the properties (our entry). The participating properties lie within the Greater Portuguese Bend landslide area, principally the Portuguese Bend and Seaview communities hatched on the schematic above.
Separately, FEMA's Cumulative Final Public Notice, posted by the City from July 2 to July 20, 2026, says the City "proposes to acquire and demolish 45 residential properties within the Portuguese Bend, Seaview, and Portuguese Bend Beach Club neighborhoods" as part of a larger group of landslide projects. It is a notice of intent under federal floodplain and wetland rules, not a funding award, and the 45 is a proposed total, distinct from the 27 homes selected for Rounds 1 and 2.
Properties acquired by the City: we add each property here once its purchase, or the City's list of selected homes, becomes public in an official record: a City announcement, a City Council agenda item (purchase or demolition), a deed recorded to the City, a demolition or coastal permit notice, or a City response to a public records request. Each entry gives the address, the date and the source. We don't guess from red or yellow tags. A tag is not the same as being selected, and the list can change as waitlisted homes move up. We don't list owners' names.

| 2 Peppertree Drive, on Peppertree Drive (a private road) just north of Palos Verdes Drive South, in the Portuguese Bend area. Our check of the City's GIS map places the parcel inside the 2025 complex boundary and outside the Abalone Cove and Klondike Canyon districts. | Not identified as a buyout-program purchase. The City's report describes a purchase paid from the General Fund; it does not mention FEMA, the buyout program or the landslide, and it gives no reason for the purchase. | Not yet. On Aug. 18, 2026 the City Council adopted Resolution No. 2026-68 (Consent Calendar, 3-0, two members absent), ratifying its earlier closed-session approval of a purchase agreement at up to $289,000 plus customary closing costs. The City said escrow will close 70 days after a court issues a new order approving the sale; the hearing was set for Sept. 22, and if the order was signed that day escrow would close on or before Dec. 1, 2026. As of Oct. 22, 2026 we had found no public record of the court's decision or of the sale closing. | After escrow closes, City staff will request quotes to demolish the structures and restore the site, for the Council to consider at a future meeting.

How the Landslide Is Measured
City GPS surveys
The City's contractors survey a dense network of GPS monuments across the complex, producing the periodic movement reports quoted everywhere (including here). This is the authoritative rate dataset, published via the City's Landslide Surveys and Land Movement Updates pages.
City survey updates →NASA/JPL airborne radar
JPL's UAVSAR instrument, flown on a Gulfstream III, mapped the slide's full extent, speed, and direction in fall 2024 (Sept. 18 to Oct. 17), independently confirming the City's ground measurements and revealing movement beyond the 2007 mapped boundary toward Abalone Cove.
JPL analysis & imagery →Boundary & hazard maps
The California Geological Survey mapped the active slides (Portuguese Bend, Abalone Cove, Klondike) inset within the ancient complex; its 2007 boundaries remain the standard reference, with the active area expanding beyond them during 2024.
Is a parcel under Ordinance 692's landslide-area rules? Movement maps don't answer that. The City's Landslide Area Development Regulations boundary map (PDF, 3.8 MB; zoom in for lot lines) shows which lots fall under Ordinance 692. Where the boundary line crosses a parcel, only the part inside it is regulated. The City also links a Landslide Area Map Address Search; the City says that map is for general information and was not prepared for legal, engineering, or surveying purposes. For questions about a parcel's status, the City asks people to email landmovement@rpvca.gov. The adopted map is Exhibit A of Ordinance 692 (PDF, 34 MB; page 24). The interactive map at the top of this page draws the same boundary from the City's GIS data, for orientation only.
City landslide area regulations → California Geological Survey →Groundwater & wells
Dewatering well output is itself a dataset: about 590 million gallons (1,813 acre-feet) pumped from the slide since September 2024 (as of November 5, 2026; City weekly report No. 26-44, a large PDF, p. 24). That report says "Ten of the original 11 DDWs installed by the City remain in service" and "One DDW will start redrill this week"; the Oct. 28 report had said nine of the original 11 (No. 26-43, p. 20), the City has not explained the change, and the Nov. 5 report gives no count of operating wells. City documents differ on how many are running: eight of nine (weekly report No. 26-42, Oct. 21), seven of nine, with two re-drilled wells offline for low production (staff report for the Nov. 4, 2026 meeting, a large PDF, pp. 7, 17–18; well table dated Oct. 19), and "8 Online," with "DDW-5 re-drill pending" (City presentation, Nov. 4, 2026 meeting, slide 2, marked as updated Nov. 3). That slide's totals (586 million gallons; 1,794 acre-feet) are not marked as updated and are lower than both weekly reports. Production is tracked well-by-well in Working Group notes and Council staff reports. The City's geologist believes the wells have contributed to the significant slowdown (City update, Aug. 26, 2026).
Where to find well data →Reading the Numbers
Inches per week is the standard unit here. For scale: 1 inch/week is about 4.3 feet per year — slow enough to walk on, fast enough to tear apart pipes, pavement, and foundations. At the 2024 peak, parts of the slide were moving at rates better measured in feet per month.
Movement is not uniform. The complex behaves like several conveyor belts of different speeds: Klondike Canyon shows generally no measurable movement, and the City's GPS points outside the mapped complex, such as those in the Seaview Tract, show none; parts of Portuguese Bend and Abalone Cove, and Altamira points outside those two slides' historical boundaries, still move. The fastest spot can shift, too: City staff say Abalone Cove's fastest-moving area in the early-October 2026 survey was its toe, at about 1.5 inches per week, which they call a change from its pattern of the past two-plus years and attribute to toe erosion from wave action in September 2026 (staff report for the Nov. 4, 2026 meeting, a large PDF, pp. 14–16). A single "average" always hides faster and slower spots — which is why per-area rates matter.
Rain is the driver. Movement historically surges one to two seasons after wet winters as water works into the deep clay layers, and eases after dry stretches and sustained pumping. City staff reported that, as of the early-October 2026 survey, the complex was moving about 30% slower than a year earlier (Oct. 2, 2025), despite an above-average rainy season (staff report for the Nov. 4, 2026 meeting, a large PDF, p. 15). The City's geologist attributes an increase since August largely to toe erosion from wave action (City update, Oct. 28, 2026) and believes the dewatering wells have contributed to the slowdown (City update, Aug. 26, 2026).
