CITY OF LAGUNA NIGUEL
CITY COUNcIL AGENDA ITEM
To: Honorable Mayor and Council Members
FROM: Jacki Scott, Public Works Director/City Engineer
DATE: March 1, 2022
SUBJECT: Approval of Amendment No. 3 to the Professional Services Agreement for On-Call Professional Engineering Services with Psomas for the La Paz Road Earth Movement Evaluation - Phase 2

RECOMMENDATION
Staff recommends that the City Council:

1. Approve Amendment No. 3 to the Professional Services Agreement for On-Call Professional Engineering Services with Psomas to provide geotechnical and engineering services for the La Paz Road Earth Movement Evaluation - Phase 2 for a total not-to-exceed amount of $287,090 and waive the RFP Process for this Amendment due to this emergency situation;

2. Approve a not-to-exceed 20% contingency of the total contract in the amount of $57,418 for unforeseen conditions or extra work and authorize the Public Works Director/City Engineer to approve additional work for a total not-to-exceed amount of $344,508, if needed; and,

3. Authorize the City Manager to execute Amendment No. 3 and future amendments to the Professional Services Agreement for On-Call Professional Engineering Services with Psomas, subject to the City Attorney making non-substantive changes.

BACKGROUND
La Paz Road was constructed in the late 1960's with one lane in each direction, then subsequently widened to two lanes in each direction in the 1990's. Throughout the years, earth movement was noticed with distortions of the pavement, , sidewalk, and parkway areas along the Niguel Regional Park interface near Rancho Niguel Road. Nearly seventy 24-inch diameter caissons were installed within the travel lanes of La Paz Road in the 1990's and early 2000's, along with a crib wall at the Orange County Regional Park in order to address the earth movement and minimize future cracking and roadway distortion.

Since the early 2000's, the City repaired cracks and minor distortion in the roadway as it occurred, but recently, the distortions have become more severe requiring the southbound number two lane to be closed to vehicular, bicycle, and pedestrian traffic.

While the travel lane has been closed, Public Works inspection and engineering staff has closely monitored the worsening cracks and pavement condition with the assistance of Psomas and Ninyo and Moore, a geotechnical engineering firm, through the City's On- Call Professional Services Agreement. In order to complete an assessment of the likely cause of the earth movement and recommend possible short-term and long-term solutions, Psomas and Ninyo and Moore will be required to install monitoring equipment and complete an assessment of the earth movement.

A map showing the vicinity and location of the earth movement along La Paz Road is provided as Attachment "A". Investigation and resolution of the roadway distress supports City Council Goal 1 (Public Safety) and Goal 4 (Infrastructure and Technology) of the City's adopted Strategic Plan.

ANALYSIS
Due to the unforeseen increase in earth movement along La Paz Road, the City Manager determined, pursuant to Subsection (3) of Section 3-6-7 of the Laguna Niguel Municipal Code, that emergency procurement of geotechnical services to assess the situation was needed. Any delay in assessment could result in material loss or damage to the roadway if immediate action was not taken. Therefore, the circumstances justified an exemption to the use of the competitive bidding process requiring the issuance of a written request for proposals and subsequent evaluation of bids.

The Public Works Department identified Psomas, one of the firms on the Public Works On-Call Professional Engineering Services List, as the most qualified consultant to provide the geotechnical and engineering services for the La Paz Road Earth Movement Evaluation given the City's knowledge of Psomas' capabilities, experience, and past performance.

On December 1, 2021, the Public Works Department requested a proposal from Psomas for geotechnical and engineering services related to the La Paz Road Earth Movement Evaluation. Psomas submitted its proposal, and cost negotiations with the consultant yielded a proposal that delivers the emergency services at a fair and reasonable cost to the City. In accordance with Subsection 3 of section 3-6-7 of the Laguna Niguel Municipal Code and under the City Manager's authority for the immediate purchase of services for emergency conditions pursuant to Section 7 (b) of the City's Purchasing Policy, the City authorized Psomas in January 2022 to conduct a Phase 1 study of the earth movement along La Paz Road.

The Phase 1 Study includes data collection and data mapping, creation of a base map, preparation of an encroachment permit to Orange County Parks, and the initial geotechnical investigation services of Ninyo and Moore, a subcontractor of Psomas.

In order for Psomas to continue its geotechnical assessment and provide a comprehensive reporting of the most likely causes of the earth movement, the City is requesting City Council approval of Phase 2 of the La Paz Road Earth Movement Evaluation. The support services will continue to be billed on a time and materials basis at the hourly rates provided in the proposal. Staff is requesting that, in approving this Phase 2 work through Psomas, that the City Council exercise its authority to waive the RFP process, pursuant to the Council's authority under Subsection (8) of Section 3-6-7 of the Laguna Niguel Municipal Code, due to the emergency condition that exists.

As deliverables for Phase 2 of the La Paz Road Earth Movement Evaluation, Psomas will provide substructure utility locating services; conduct preliminary coordination with utility companies; geotechnical engineering investigation and analysis; traffic control plans and conceptual street improvement plans and cost estimates; prepare a comprehensive pre- design report documenting its findings and recommendations; and provide project management services and quality control services. Throughout the evaluation of Phase 2, mitigation measures to reopen the closed lane along La Paz Road will be examined and a schedule for reopening the lane will be developed.

Staff recommends approving Amendment No. 3 to the Agreement with Psomas to provide geotechnical and engineering services for the La Paz Road Earth Movement Evaluation - Phase 2 for a total not-to-exceed amount of $287,090 (Attachment "B").

Additionally, due to the nature of the earth movement issues, it is anticipated that unknown conditions may present themselves during further assessment of the geotechnical solutions and conceptual street improvement plans. To address these concerns in a timely fashion, it is recommended that a 20% contingency be established on this project to complete the investigation, analysis, and recommendations. Typically, a 10% contingency is the standard recommendation; however, this project poses a higher risk of added costs and a 20% contingency will facilitate a comprehensive assessment of the earth movement issues. Any additional cost above the 20% contingency will return to the City Council for approval. Therefore, staff also recommends approving a not-to- exceed 20% contingency of the total contract in the amount of $57,418 for a total not-to- exceed amount of $344,508.

ALTERNATIVES CONSIDERED

1. The City Council may decide not to approve Amendment No. 3 to the Professional Services Agreement with Psomas and direct staff to issue an RFP. Staff believes that issuing an RFP will not result in more desirable proposals and would cause delays in addressing the La Paz Road earth movement issues and prolong the lane closure.

2. The City Council may decide not to approve Amendment No. 3 to the Professional Services Agreement with Psomas. This alternative is not recommended as it will result in delays in addressing the La Paz Road earth movement issues and initiating discussions with the County of Orange.

FISCAL REVIEW
Funding for Amendment No. 3 will be split across two fiscal years. In Fiscal Year 2021- 22, $150,000 will be allocated from the Public Works Department operating budget. Fiscal Year 2022-23 funds will be budgeted in the CIP.

LEGAL REVIEW
The City Attorney's Office has reviewed Amendment No. 3 and this staff report and has approved both documents as to form.

CONCLUSION
Staff recommends that the City Council:

1. Approve Amendment No. 3 to the Professional Services Agreement for On-Call Professional Engineering Services with Psomas to provide geotechnical and engineering services for the La Paz Road Earth Movement Evaluation - Phase 2 for a total not-to-exceed amount of $287,090 and waive the RFP Process for this Amendment due to this emergency situation;

2. Approve a not-to-exceed 20% contingency of the total contract in the amount of $57,418 for unforeseen conditions or extra work and authorize the Public Works Director/City Engineer to approve additional work for a total not-to-exceed amount of $344,508, if needed; and,

3. Authorize the City Manager to execute Amendment No. 3 and future amendments to the Professional Services Agreement for On-Call Professional Engineering Services with Psomas, subject to the City Attorney making non-substantive changes.

Santa Ana, Arizona 92707
Subject: Proposal for Final Geotechnical Landslide Evaluation La Paz Road Between Rancho Niguel Road and Kings Road
Laguna Niguel, California
Dear Ms. Davis:

In accordance with your request, we have prepared this proposal to perform a geotechnical evaluation of the observed landslide movement located along the west side of La Paz Road between Rancho Niguel Road and Kings Road, adjacent to Laguna Niguel Regional Park, in the city of Laguna Niguel. We have prepared this proposal based on our discussions with you and with representatives of the City of Laguna Niguel (City), several site visits, preliminary review of existing files and documents for the site provided by the City, as well as review of readily available geological literature for the site vicinity. The purpose of our geotechnical services will be to evaluate the soil and geologic conditions at the site in order to evaluate the causes of the observed road distress and landslide movement as well as develop recommendations for short term and long term repair and mitigation of the landslide movement.

Based on our preliminary review of documents provided by the City, we understand that La Paz Road was originally constructed in the 1980s as a two-lane road. The road was widened to a four lane (two in each direction) in 1997 by using crib-wall retaining structures and compacted fill along the western edge of the alignment. Movement and distress was reported periodically during this time period. We understand that mitigation measures included the installation of 54, twenty-four inch- diameter caissons in 2001 to depths of approximately 30 feet. An additional 13, twenty-four inch- diameter caissons were installed to depths of approximately 50 feet, sometime after May 2008.

Based on recent site visits (December 2 and December 6, 2021), the most highly impacted area of the roadway extends approximately 500 feet along the western edge of the La Paz Road, roughly 1,000 feet north of Kings Road. Distress features include depressed and undulatory roadway and sidewalk and tension cracks and separations in the curb-and- gutter. Cracks and separations were observed in the asphalt pavement (which we understand was resurfaced in approximately May of this year) up to roughly two to three inches wide. The sidewalk in the area is tilted and cracked and 475 Goddard, Suite 200 | Irvine, California 92618 | p. 949.753.7070 | www.ninyoandmoore.com the fences adjoining the sidewalk have been distorted and racked out-of-plum. Numerous utilities were observed under the pavement or sidewalk of La Paz Road in this area including potable water, reclaimed water, gas, fiber optic cable, and telephone. We understand that La Paz Road and the adjoining sidewalk and upper portions of the slope in this area are part of the City of Laguna Niguel; the lower portions of the slope are part of Laguna Niguel Regional Park and belong to the Orange County Parks Department.

Based on review of geotechnical reports and published geologic maps, the area is mapped as underlain by a number of ancient landslides, which are in turn underlain by the Miocene-age Capistrano Formation. The Capistrano Formation is known for slope instability issues and landsliding in southern Orange County.

SCOPE OF SERVICES
We have perpared and presented a scope of work for the preliminary project review and evaluation for the project that included review of existing reports and information, performance of initial site mapping and utility mark out, and preparation for subsurface evaluation. Our scope of services for this phase of evaluation will consist of a geotechnical subsurface evaluation including laboratory analyses, engineering analyses, and preparation of a geotechnical report. Our services for this phase of work will include the following:
• Continuing project coordination.
• Traffic control measures will be performed during field operations, as appropriate, in general accordance with the previously approved traffic control plans and the WATCH manual. • Performance of a geotechnical subsurface evaluation consisting of the following:
• Drilling three (3) large-diameter soil borings (approximately 30-inches in diameter) to depths of up to approximately 60 feet below existing grades or to refusal (whichever is shallower).

The borings will be backfilled with cement bentonite grout and soil cuttings in accordance with the boring permit. Excess soil may be spread in suitable areas of the site or on the adjacent County Parks property.

The purpose of the large diameter borings will be to allow our engineering geologists to enter the borings via a winched cage to directly observe and log the earth materials and the geologic structure. This is the most accurate and effective method to evaluate the nature, depth, and thicknesses of the earth materials and to measure the location and orientation of bedding, fractures, clay seams, and slip or slide planes. Several large-diameter borings Ninyo & Moore | La Paz Road Landslide Evaluation, Laguna Niguel, California | 04-03473| January 7, 2022 2 have been performed in the area by other consultants during previous evaluations. However, the slide has moved since those explorations and the new borings will give us the most up- to-date look at the existing subsurface conditions. Based on the results of the background review and early evaluation, the proposed number and location of the large-diameter borings may be modified.
• Drilling three (3) small-diameter borings (approximately 8-inches in diameter) to depths of up to 70 feet below existing grades or to refusal (whichever is shallower). These borings would be drilled on the Orange County Parks Department property at or near the base of the slope below La Paz Road. The borings will be backfilled with cement bentonite grout in accordance with the boring permit. Excess soil may be spread in suitable areas of the site or on the adjacent County Parks property.

The purpose of these borings is to observe and sample the earth materials on or near the base of the slope and landslide and to observe the depth to groundwater at the base of the slope. Based on the results of the background review and early evaluation, the proposed number and location of the small-diameter borings may be modified. • Drilling five (5) additional small-diameter borings (approximately 8-inches in diameter) to depths of up to 70 feet below existing grades or to refusal (whichever is shallower) and installation of inclinometer casings. We propose to install two inclinometers along the east side of La Paz Road, one inclinometer in the median of La Paz Road, and two incliniometers along the west side of La Paz Road in the area of the recent slope movement. Excess soil may be spread in suitable areas of the site or on the adjacent Orange County Parks property.

Based on the results of the background review and early evaluation, the proposed number and location of the small-diameter borings may be modified.

The rationale for the number and placement of the inclinometers is several fold:
• The three inclinometers proposed to be placed on the east side of La Paz Road and within the median will be used to delineate the area of impact and landslide movement. • The purpose of the two new inclinometers along the western edge of La Paz Road would be to provide additional evaluation of movement within the existing slide mass. There are several existing inclinometers on the site, installed by other consultants, and may be available to be monitored. However, the existing inclinometers have experienced some degree of off-set due to the recent movement of the slope. Some may have become nonfunctional or may become nonfunctional at some future date due to bending or shearing of the inclinometer pipe. In that case, the two new proposed inclinometers Ninyo & Moore | La Paz Road Landslide Evaluation, Laguna Niguel, Califomia | 04-03473 | January 7, 2022 3 would provide the ability to continue to observe and monitor movement of the slope during our evaluation and before and during repair operations. • The borings will be logged by professionals from our firm, and bulk and relatively undisturbed soil samples will be collected at selected intervals for laboratory testing. The large-diameter borings will be down-hole logged by State-certified engineering geologists from our firm.

Laboratory testing of representative soil samples which may include in-situ moisture and dry density, sieve analyses, Atterberg limits, direct shear strength, and soil corrosivity, as applicable.

The laboratory testing will provide several basic parameters used for slope stability analyses including weight of the overlying soil mass, moisture content, and plasticity and shear strength of the various layers and types of earth materials present in the slope and landslide. • The new inclinometers and existing operational inclinometers would be read approximately two times per week for a period of approximately three months. Reading frequency after that period of time will be evaluated based on the results of our initial readings and the subsurface field evaluation. The frequency of readings may be increased or decreased based on our findings and evidence of continued movement of the slope.

Data compilation and geotechnical analysis of the background information, field, and laboratory data. Our analyses will include prepration of new geologic cross-sections based on previous and new subsurface data and performing slope stability analyses. The geologic cross-sections will depict the representative scaled profile of soil, formational material (along with the appropriate bedding conditions), potential landslide surface or zones of reshear, locations of signficant clay seams, and the landslide mass through the areas of concern at the project site.

The ground surface profile will be presented in detail along with signficant surficial features or improvements. Additionally, the geologic cross-sections will also present the possible groundwater table and zones of seepage based on available and new subsurface data. Each geologic cross-section will be used in developing two-dimensional slope stability model and limit equilibrium methods of analyses will be performed using a state-of-the-art slope stability analysis computer program. Both force and moment equilibriums will be evaluated for each cross-section, and static and seismic factors of safety of the potential slide planes will be analyzed. Several hundreds of potential failure surfaces (i.e., slide planes) will be evaluated for each cross-section, and the factors of safety of the most critical failure surface will be reported The objectives of such rigorous analyses will be to (1) evaluate the current stability of the affected slope; (2) compare the potential sliding planes observed in our borings and/or inferred from the inclinometer monitoring data to those obtained from the slope stability analyses; and Ninyo & Moore | La Paz Road Landslide Evaluation, Laguna Niguel, California | 04-03473 | January 7, 2022 4 (3) develop effective mitigation measures that would enhance the factors of the safety against global instability and bring those to at or above the accepted standard. • Preparation of a geotechnical report presenting our findings, conclusions, and recommendations.

The purpose of our geotechnical services was to make a preliminary evaluation of the PROFESSIONAL soil, geologic and groundwater conditions associated with the preliminary design

AFFILIATIONS
for mitigating erosion of Alta Mira Canyon which is located within the Abalone Cove Association of Environmental and landslide in Rancho Palos Verdes. The project consisted of an evaluation of four Engineering Geologists drainage improvement options that will aid in managing the storm water flow through the Alta Mira Canyon and keeping excess runoff from entering cracks and fissures Geological Society of America
in the landslide. The options included one or a combination of various mitigated San Diego Association of Geologists measures, such as a canyon fill, new storm drains, energy dissipation systems, culverts, walls, gabions, retention basins, inlet and outlet structures and bypass systems. Services have consisted of review and research of available geotechnical literature and aerial photographs, site reconnaissance and geologic mapping, data compilation and analysis and partial preparation of a preliminary geotechnical report.

The project included a 400-foot-long cut slope along the north side of Sunset Boulevard between Coronado Terrace and Waterloo Street. The existing cut slope ranged from 10 to 40 feet in height and was very steep with inclinations of approximately 0.5 to 1 (horizontal to vertical) to vertical at some locations. The slope exposed dense sandstone of the Puente Formation. The sandstone ranged Ronald D.

Principal Geologist
from uncemented friable material to well cemented concretion layers. Mr. Hallum provided logging of large-diameter borings and technical review and input for the preliminary cost estimates for the conceptual stabilization alternatives Ocean Trails Golf Course, Rancho Palos Verdes, California:Principal field and project geologist for the forensic evaluation of landsliding at the Ocean Trails Golf Course (now Trump National Golf Club Los Angeles) in Rancho Palos Verdes, California On June 2, 1999 an approximately 16-acre ancient landslide on the coastal bluff was reactivated, sliding approximately 50 feet toward the ocean. The ancient landslide destroyed much of the 18th fairway and green along with adjacent improvements including an active County sewer line. The forensic evaluation included multiple geotechnical firms in a group investigation. The geologic setting included gently to moderately tilted beds of the Monterey Formation. The Monterey Formation at this locality included interbedded sequences of fine silty sandstone, siltstones, shales, dolomitic shales, siliceous zones, and bentonitic ash beds. The basal rupture surface was formed along a relatively continuous bentonite layer at a depth of approximately 90 feet. The geologic evaluation included detailed geologic mapping, 26 large diameter borings, 2 rotary wash continuous core borings, 12 inclinometers, and the excavation and evaluation of buried sewer lines and artificial lakes. The analysis included preparation of multiple geologic cross sections, slope stability analysis, and evaluation of potential reactivation causes including seismic activity, precipitation, wave erosion, irrigation, construction activities, lake leakage, and sewer line leakage. and construction for the SR 125 Toll Road project. The southern abutment of the SR-125 bridge, that was to ultimately span the Otay River Valley, was located on top of the identified landslide mass. Based on our field and subsurface evaluations, our original recommendation was to remove the landslide materials within the SR-125 right-of-way (ROW) down to below the basal rupture surface and to replace these materials with compacted fill soils. However, due to environmental constraints, portions of the landslide mass directly adjacent to the ROW could not be disturbed. Grading of the landslide began in June 2005. During grading, Mr. Hallum made daily visits to the site to observe and map the exposed geologic structures and conditions. During removals, he observed that the landslide mass was a series of small to large landslide blocks that had moved as translational masses along relatively flat-lying basal surfaces. The majority of the movement was observed to have failed along a basal surface located at an elevation between approximately 221½ and 230 feet above mean sea level. To reduce the chances for the backcut failures extending out of the ROW and into the environmental exclusion areas, and based on our observations and mapping during removals, we performed additional calculations and provided revised recommendations for reducing the size of the removal and including construction of a gravity buttress at the base of the slope to achieve a suitable factor of safety. These measures were implemented and provided suitable factors of safety. Grading of the buttress and slope beneath the bridge abutment was completed by March 2006.

The plan included the design and installation of thirteen continuously monitored in-place inclinometer and tilt meter systems that were solar powered and transmitted data via cellular modem to a web-based monitoring service. The plan established automatic alert levels based on ground or tower/pole movement and recommendations for actions.

Our services included review and maintenance of the monitoring system and implementation of actions following automatic alarms.

Asilomar Boulevard Landslide Evaluation, Pacific Palisades, California Ninyo & Moore was retained to evaluate an active landslide complex beneath Asilomar Boulevard in Pacific Palisades, California. The landslide extends from a headscarp area beneath Asilomar Boulevard down a 200-foot-high slope to Pacific Coast Highway. The active movement of the landslide threatened to undermine the City-owned Asilomar Boulevard and impact lower properties occupied by two mobile home parks. The hillside terrain facing the ocean is underlain by tilted siltstone and shale beds of the Modelo Formation. The hillside includes several landslides and periodic slope movement has been documented since 1958. Our services included compilation of previous geotechnical data, including boring logs, monitoring well data and inclinometer readings.

Our field services included geologic mapping of the landslide areas and subsurface exploration. Nine large diameter borings to depths of 40 to 90 feet were drilled and down-hole logged by our engineering geologists. Two additional slope inclinometers were installed and three new monitoring wells were installed. Periodic groundwater and inclinometer measurements were performed during our field evaluation. The previous geologic data and our new subsurface information were used to Ninyo & Moore | La Paz Road Landslide Evaluation, Laguna Niguel, California 04-03473| January 7, 2022 7 prepare multiple geologic cross sections. Laboratory testing included in-situ moisture and density, gradations, Atterberg limits, expansion index, and shear strength testing. Stability analyses were performed to evaluate the existing slope stability, to evaluate alternative stabilization methods and to evaluate temporary construction excavation conditions (back-cut stability). Alternative stabilization measures considered included drilled shear pins with tie-back anchors, buttress shear keys, and hydro-augers for dewatering. Our work was performed with on-going consultation and review by the City Geotechnical Engineering Division (GED) as well as consultants for the mobile home park land owners. Project challenges included difficult drilling in dense/cemented materials, groundwater seepage conditions, limited access in steep terrain, and the complex subsurface conditions that included multiple landslide zones. Our evaluation delineated the active landslide zone and developed mitigation measures to stabilize Asilomar Boulevard and to provide practical measures to enhance the stability of the lower slope areas.

Haskell Canyon Switching Station, Los Angeles County, California Ninyo & Moore provided geotechnical consulting services during the design phase of the Haskell Canyon Switching Station project located near Santa Clarita in Los Angeles County for the Los Angeles Department of Water and Power (LADWP). We performed an initial geotechnical evaluation for the proposed switching station, transmission towers, access roads and associated improvements.

Proposed cut slopes and fill slopes exceed 150 feet in height. The stability of proposed cut and fill slopes and large-scale landslides were evaluated with 10 bucket auger borings over 90 feet in depth and 18 backhoe test pits.

During grading to stabilize a large on-site landslide, the landslide began to move, threatening two large electrical transmission towers. We performed additional mapping, subsurface evaluation, and slope stability analyses and within a week had designed a new stabilization method including placement of approximately 130, thirty- to fifty-foot long, three-foot diameter reinforced shear pins to stabilize the landslide and overlying slope. We then performed observation and confirmation services during installation of the shear pins to confirm design placement and depths had been attained. After completion of the shear pin installation and construction, the area has shown no evidence of additional movement.

Ocean Trails Golf Course, Rancho Palos Verdes, California Ninyo & Moore performed a forensic evaluation of landsliding at the former Ocean Trails Golf Course (now the Trump National Golf Club Los Angeles) in Rancho Palos Verdes, California. An approximately 16-acre ancient landslide on the coastal bluff was reactivated, sliding approximately 50 feet toward the ocean. The ancient landslide destroyed much of the 18th fairway and green along with adjacent improvements, including an active County sewer line. The forensic evaluation included multiple geotechnical firms in a group investigation. The geologic setting included gently to moderately tilted beds of the Monterey Formation. The Monterey Formation at this locality included interbedded sequences of fine silty sandstone, siltstones, shales, dolomitic shales, siliceous zones, and bentonitic ash beds. The basal rupture surface was formed along a relatively continuous bentonite layer at a depth of approximately 90 feet. The geologic evaluation included detailed geologic mapping, 26 large diameter borings, 2 rotary wash continuous core borings, 12 Ninyo & Moore La Paz Road Landslide Evaluation, Laguna Niguel, California | 04-03473 January 7, 2022 8 inclinometers, and the excavation and evaluation of buried sewer lines and artificial lakes. The analysis included preparation of multiple geologic cross sections, slope stability analysis, and evaluation of potential reactivation causes including seismic activity, precipitation, wave erosion, irrigation, construction activities, lake leakage, and sewer line leakage.

Mount Soledad Road, La Jolla, California
Ninyo & Moore evaluated the October 3, 2007 landslide on Soledad Mountain Road in La Jolla, California for the City of San Diego. The project included an evaluation of the cause of the landslide, evaluation of conditions at homes involved in litigation. The project presented issues for geotechnical investigation under a critical schedule to evaluate the causes of landslide reactivation and to stabilize the hillside and re-open Soledad Mountain Road, a major artery, for traffic. Interim slide stabilization had to also occur prior to onset of winter rains. Our investigation had to begin immediately upon notification of the slide movement by the City. Large-diameter borings were downhole logged by engineering geologists to evaluate landslide geometry and characteristics.

Simultaneously small diameter borings were used to obtain hundreds of samples for soil moisture and other testing in order to identify if water from existing utilities and other sources could have been a contributing factor to slide reactivation. Construction repairs utilized a combination of grading, reinforced concrete shear pins, geofabrics and drainage improvements for stabilization.

Our field evaluation included drilling and logging small diameter borings, excavating trenches and test pits, downhole logging of large diameter borings by a Certified Engineering Geologist, logging and sampling shear pin borings, and detailed evaluations of the homes damaged or destroyed in the landslide. Our laboratory tested over 2,500 samples in support of the evaluation.

Via de las Olas Landslide, Pacific Palisades, California Ninyo & Moore was retained to perform a preliminary geotechnical evaluation for the Via de las Olas Landslide in Pacific Palisades, California, and to develop conceptual methods to stabilize portions of the Via De Las Olas roadway located above and on portions of the landslide.

Our services included subsurface exploration consisting of drilling, logging, and sampling of four small-diameter borings and three large-diameter borings along the top of the landslide headscarp.

Four 85-millimeter (3.34-inch) Slope Indicator casings were installed and monitored in the small- diameter borings and downhole logging was performed in the large-diameter borings. The large- diameter borings were backfilled with one-sack slurry and the soil cuttings from the drilling activities were placed in bins and transported off site.

Ninyo & Moore also performed heavy brush clearing on the landslide mass in order to located, assess, and clean out a subsurface hydrauger drainage system consisting of 32 hydraugers that were installed in the 1980's to drain and help stabilize the landslide mass. The hydrauger cleaning consisted of inserting a hydro-jet nozzle into the 1½ inch PVC pipe of the daylighted portion of the hydraugers to depths of up to approximately 410 feet. The hydro-jet injected approximately 3,000 pounds per square inch of water pressure to clean out a variety of materials, including sediments, roots, precipitates, and decomposing organic matter.

Ninyo & Moore La Paz Road Landslide Evaluation, Laguna Niguel, California 04-03473 January 7, 2022 Data compilation and geotechnical analysis of the information obtained from our background review, field reconnaissance, subsurface evaluation, and laboratory test results were performed in order to present several conceptual repair alternatives to stabilize the Via de las Olas roadway under various funding scenarios. Ninyo & Moore also prepared preliminary cost estimates for the conceptual stabilization alternatives.

OCTA/Metrolink/Mile 195 Slope Repair, San Juan Capistrano, California Ninyo & Moore was retained to provide geotechnical consulting services relative to design alternatives to stabilize a landslide adjacent to Oso Creek in San Juan Capistrano affecting a city street, several underground utility lines, and the track alignment for rail traffic between Orange and San Diego Counties. Our services included geologic field mapping, review of aerial photographs and existing background materials including boring logs and inclinometer data, slope stability calculations and other geotechnical analyses to develop repair alternatives. Based on the results of our evaluation, partial filling of Oso Creek and construction of a lined channel was recommended to stabilize the landslide, as well as mitigate the potential for slope instability in adjacent areas.

Harris/San Ramon Canyon Storm Drain, Rancho Palos Verdes, California The City of Rancho Palos Verdes planned to improve drainage conditions along the San Ramon Canyon, which traverses the South Shores Landslide to the ocean. Erosion and siltation along the canyon have resulted in clogging of storm drains, flooding and undermining canyon slopes and activation of the Tarapaca Landslide. The drainage improvements include construction of canyon subdrain systems, partial canyon filling and buttressing of the Tarapaca Landslide, construction of 4,000 feet of 54-inch storm drain, nearly 2,000 feet of tunneling, construction of a mid-canyon inlet structure, construction of a sea-bluff outlet structure and construction of access roads in the relatively steep landslide and canyon terrain. The project is intended to improve drainage along the canyon and reduce the potential for future landslide movement. Ninyo & Moore performed a geotechnical evaluation for the design of the project elements. Our services included coordination with the City geologist and design team, review of geologic background data, field geologic mapping, exploratory borings to depths up to 131 feet, continuous core sampling, optical televiewer and suspension logging of boreholes, backhoe test pits, laboratory testing and engineering analysis.

Multiple geologic cross sections were prepared to evaluate the planned construction activities and slope stability. Our geotechnical report for the project included design recommendations for the canyon grading, tunneling, material engineering properties, trenching, and inlet and outlet foundation systems. Inlet and outlet structures involved temporary excavations utilizing soldier piles and tie-back anchors. Soldier piles were also designed to stabilize planned access road slopes.
