Dear Mr. Schwartz,
In accordance with your request and authorization, G3SoilWorks, Inc. (G3), has performed a
preliminary geotechnical investigation / engineering geologic evaluation for the proposed new
residence at 2050 East Oceanfront in Newport Beach, California. This report was prepared
based on information provided by you, experience with similar projects, review of public and
proprietary information, limited subsurface exploration, and laboratory testing performed by this
office. Included herein is a summary of our engineering geologic evaluation findings and
geotechnical recommendations for ground improvement, site excavations / grading, foundations
design, and other aspects related to design and construction of the proposed new residence
structure.
SITE LOCATION / DESCRIPTION
The subject property is located near the eastern end of Balboa Peninsula and southwesterly of
the intersection of M Street and East Oceanfront in the City of Newport Beach, California
(Figure 1, Attached). The site is part of a relatively narrow, beachfront, residential lot
approximately 40 feet wide by 80 feet long and 3184± square feet in area (Reference 1). An
approximately 20-feet-wide alleyway bounds the site to the north; existing residences bound the
site to the east and west (2054 and 2046 East Oceanfront, respectively); and Balboa Beach
bounds the site to the south. Existing site grades (according to Reference 1) range between
approximately 12.5-19± feet above NAVD 88 (North American Vertical Datum of 1988). The site
is located approximately 400± feet inland of the Pacific coastline and 1000± feet westerly of
West Jetty View Park and the inlet / outlet channel of Newport Harbor.
An existing 1980s-era, two-story, single-family residence with subterranean / split-level garage,
bathroom, and laundry room currently occupies the site. Figure 2 is included as an attachment
and shows the generalized configuration of the residence with respect to the garage (shown in
gray), front entryway (blue), and rear living room (green). Based on review and interpretation of

survey mapping by Apex Land Survey (Reference 1) and measurements taken onsite, the
garage, laundry room, bathroom, and storage area Finish Surfaces (F.S.) appear to be at
approximately Elevation (El.) 11± feet above NAVD 88; F.S. for the front entryway and rear
living room appear to be at El. 18± and 19± feet, respectively. The beach fronting the southerly
rear of the property (El. 18± feet) is approximately 5± feet higher than the driveway fronting the
alleyway / East Oceanfront to the north (El. 13± feet). Existing Grades (E.G.) along the
centerline of the existing alleyway slope east-southeast from El. 12.80 feet to El. 12.69 feet
(0.11 feet) over a distance of approximately 40 feet (slope = 0.00275 vertical feet per horizontal
foot; S = 0.00275 ft/ft).
The existing garage occupies approximately half of the existing residential footprint and is
approximately 2.3± feet below the adjoining driveway. A relatively steep, concave- / convex-
sloped, interior driveway provides access to the existing sub-level garage and associated
laundry / bathroom / storage areas. An existing Concrete Masonry Unit (CMU) retaining wall is
located at the rear of the garage and is approximately 8-feet-high, with adjoining easterly and
westerly retaining walls that retain soil to within approximately 3 feet of property line. Existing
retaining wall heights along the east and west side of the property vary between approximately
3-9± feet and 7± feet in height, respectively. The existing living room and front entryway are at
least partly supported by retained soils and existing slab-on-grade construction.
PROJECT DESCRIPTION / PROPOSED DEVELOPMENT
Overview
Current plans provided by the Project Architect indicate that the existing residence is to be
demolished and replaced with a new two-story, single-family residence with basement-level
garage, driveway, recreational room, powder room, laundry, and storage closet. Preliminary
sections indicate that the Basement Floor is to be set at El. +7.35 (NAVD 88), requiring
excavations down to El. +4.00 or approximately 9 feet and 13-14 feet below the existing front
driveway and rear patio / beachfront, respectively. The first-story Living Room and Kitchen floor
levels will be set at El. +16.37 and will be adjoined at the southerly rear by a depressed Front
Yard at El. +15.99. Engineering geologic / geotechnical considerations for the proposed
development include:
Demolition of the existing residence and sub-level retaining walls;
Temporary shoring installation and below-grade excavations along property line;
Foundation construction including mat slab and basement retaining walls;
Shallow groundwater occurring at depths of approximately 4-13 feet below existing site
grades;
Mitigation of seismic hazards including liquefaction and seismic settlement;
Possible coastal flooding hazards associated with long-term sea level rise, astronomical
tides, storm activity, and tsunami hazards.

Newport Beach, California
The major factors listed above are addressed herein based on the findings of our geotechnical
investigation and engineering geologic evaluation of the project. The major geotechnical factors
involve below-grade excavations and construction of the proposed basement / garage level and
mitigation of issues related to shallow groundwater intrusion, moisture / vapor mitigation, and
earthquake-related liquefaction / dynamic settlement.
Earthwork / Excavations / Foundations
According to the preliminary architectural basement plan (Figure 3, attached) and sections,
below-grade excavations will be required and will extend to a Rough Grade Pad Elevation of
+4.0 feet NAVD 88. A preliminary 30-inch-thick mat slab, 3-inch waste slab, and 3-inch
protection slab is proposed below the proposed basement with associated retaining walls. Our
recent groundwater monitoring work for the site (period of June 21st, 2021, through December
10th, 2021) indicates that groundwater elevations (unconfined, occurring in Quaternary beach
sand) vary from approximately as deep as +4.5 feet to as shallow as +6.7 feet above NAVD 88.
A secant pile / deep soil mixing program is planned to mitigate liquefaction and shallow
groundwater intrusion. Based on discussions with a potential design-build ground improvement
contractor for the project, site dewatering will not be required to accomplish the subject
excavation work and new residence construction, as the secant piles / soilcrete is intended to
render the excavation impervious, thereby mitigating shallow groundwater intrusion during
construction.
Secant Piles / Deep Soil Mixing (DSM) Program
Secant pile installations and deep soil mixing / soil-cement by others are planned to provide
temporary shoring along property lines, cut off groundwater / waterproof the excavation, and
mitigate liquefaction as part of the final construction. The secant piles and soil cement columns
will both be constructed using soil cement / Deep Soil Mixing (DSM) to tentative minimum
depths of 23-28 feet below existing ground surface or El. -10 feet (NAVD 88). This method of
ground improvement will be implemented to mitigate liquefaction potential and groundwater
intrusion and uses a truck-mounted drilling rig equipped with specialty purpose-built stem and
mixing tool arrangement. As the mixing tool is advanced into the soil by a combination of
rotation and crowd force, a grout slurry (comprised of cement and water) is injected through the
hollow-stem and blended with the soil mix, creating “soilcrete” columns. Once cured, the DSM-
treated sands are cemented into relatively impervious, sandstone-like cylinders, thereby
increasing their strength, limiting their permeability, and mitigating liquefaction potential. An
added benefit of the secant pile / DSM program is the mitigation of groundwater intrusion that
during construction – provided that the work is performed carefully to limit / prevent
imperfections in the cement treatment which would allow groundwater seepage through
permeable / uncemented zones of sand.
In general, the planned secant pile / DSM program will proceed as follows:
Secant piles (3-feet-diameter or per designer recommendations) will be installed along
property lines and overlapped to form a cutoff to horizontal groundwater flow and provide

temporary shoring during basement level construction – the planned secant piles will
utilize higher strength cement mix and steel reinforcement (i.e., H-Beams);
Interior soilcrete columns (6-feet-diameter or per designer recommendations) will be
installed through the interior pad areas utilizing a lower strength cement mix to enhance
excavatibility during construction – the resulting interior soilcrete columns serve to
mitigate liquefaction and groundwater intrusion from below the treatment zone.
Once installation and curing of the secant piles and interior soilcrete columns is complete,
excavations will be performed to accommodate mat slab / basement retaining wall construction.

GEOLOGY
Regional Geologic Setting
The Los Angeles and Orange County coastal areas are adjacent to what is referred to as
California’s "Continental Borderland" geomorphic province – representing an area of transition
between continental and marine environments that adjoin the southern Los Angeles Basin
(LA Basin; Figure 4, below). Over the past 20 million years of geologic time, tectonic
development of the southern San Andreas Fault Zone (SAFZ) and other major faults of the
southern San Andreas Fault System has broken the southern California landscape into three (3)
major geomorphic provinces (i.e., Transverse Ranges to the north; Peninsular Ranges to the
south and east; and Continental Borderland to the southwest). The LA Basin, a major structural
depression / tectonic pull-apart / sedimentary basin, forms the join between these provinces and
began developing during early to middle Miocene time (15-20 million years ago). The LA Basin
initially formed an offshore, deep-marine environment that served as a depocenter for marine
sediments being shed from the continental mainland to the north and east. Extensional block-
faulting and volcanism during that time created a trough-like graben that deepened with time
and continued to infill. During Pliocene time (3-5 million years ago), the region began to
transtend (pull-apart, shear, and rotate) as the southern SAFZ began evolving into a major right-
lateral transform fault between the North American and Pacific tectonic plates of the earth.
Within the last 2-3 million years, north-south oriented tectonic compression and associated slip
along frontal faults of the central Transverse Ranges have caused rapid uplift and erosion of the
Santa Monica and San Gabriel mountains, blanketing / infilling the northern margins of the
LA Basin with terrestrial / water-transported sediments. Throughout Pleistocene time, over the
last 1-2 million years, deformation and growth-faulting along the Newport-Inglewood / Rose
Canyon Fault Zone (NIRCFZ; Figure 4) has formed a series of topographic ridges /
transpressional uplifts that disrupted / impounded marine and terrestrial sediments deposited by
the ancestral Santa Ana, Los Angeles, and San Gabriel river systems. The boundaries of the
Borderland changed as sediments continued to prograde outward and fill the trough-like
LA Basin. Coupled with regional tectonic uplift of the coastline, this caused the Pacific Ocean to
regress, displacing the shoreline southwestward. Antecedent drainages / water-gaps also
developed as ancient river systems incised / cut across the Newport-Inglewood uplift. Today,
the boundaries of the Borderland and southwestern LA Basin are delineated by the onshore and
offshore segments of the NIRCFZ, which bounds the Borderland to the northeast and
juxtaposes Catalina Schist basement rocks of the Borderland against granitic / metamorphic
basement rocks of the Peninsular Ranges at depths on the order of 10- to 20-thousand feet
below the surface. The project site is located in the coastal zone of Newport Beach, near the
mouth of the modern Santa Ana River and NIRCFZ’s intersection with the coastline. Onshore,
the NIRCFZ continues northwest as the Newport-Inglewood Fault Zone – a major / historically
active fault line believed to be the causative fault in the 1933 Magnitude (Mw) 6.4 Long Beach
Earthquake.

Surficial Geology / Geomorphology / Site History
Pre-Development History (1896)
The project site is located near the “Wedge” of Balboa Beach and southeastern terminus of
Balboa Peninsula – approximately 4.8± miles southeast of the modern Santa Ana River
Channel, 400± feet inland of the Pacific Ocean / modern coastline, 1,000± feet westerly of the
Newport Harbor inlet channel, and 1,400± feet northwest of the Wedge and Newport Harbor
Jetty. Review of historic topographic maps dating back to 1896 (Figure 5, below) indicates that
the immediate vicinity of the site previously occupied the historic southeasterly terminus of
Balboa Peninsula – a late Holocene-age sand spit / bar / barrier beach created by the Santa
Ana River (SAR) and its interaction with the coastline. Throughout latest Holocene time (the last

2- to 3 thousand years or so) discharge of terrestrial sediments from the SAR and other local
sources along the coast have been transported by wave-driven longshore currents, littoral drift,
and wind-blown / eolian sedimentation, creating the coastal beaches of southern California.
Historically, the site also appears to have straddled the intertidal estuary of Newport Bay and its
“natural” inlet at the southernmost end of the peninsula. Note that the location of the site shown
on Figure 5 is approximate, and appears to indicate that the site is likely located in an area
previously occupied by a bar mouth and cross-cutting, intertidal channels of the Santa Ana
River / Newport Bay.

foot contour interval) topographic map showing approximate location of project site (green bullseye) on
historic Balboa Peninsula, adjacent to Newport Bay (image from Google Earth overlay; site location is
approximate; north is up; not to scale; for illustrative purposes only).
Early Historic Development (1927)
Beginning in the late 1890’s / early 1900’s, the tidal mudflats of Newport Bay were dredged and
reconfigured to create Newport Harbor. Review and analysis of historic air photos indicates that
the site itself occupies ground that did not exist in 1927 (Figure 6, below) and was essentially
open-water just offshore of the peninsula. The ground that currently supports the site / vicinity is
understood to be comprised of littoral beach sand that accumulated following construction of the
Newport Harbor Jetty – forming the “Wedge” of Balboa Beach. In general, the southerly
terminus of Balboa Peninsula represents a quasi-natural / man-made, historic landform that was
created through a combination of naturally occurring coastal sedimentation processes (i.e.,

wave erosion and longshore drift), eolian / wind-blown sedimentation, and placement of man-
made fills that likely include soils dredged from the adjacent Newport Harbor inlet channel.
Evidence of man-made fills includes the presence of inferred / buried rip rap encountered in our
exploratory borings (B-1, B-2, and B-3) at depths of 11-14± feet below the existing residence
driveway at approximately El. -1 to +2 feet NAVD 88. This inferred rip rap is understood to be
representative of imported materials (grouted boulders, rock aggregate, concrete, etc.) used in
the construction of the nearby Jetty and/or a historic rail line. It is possible that the rip rap was
placed by accident and/or on purpose as part of a temporary revetment intended to stabilize the
shoreline following an apparent, possibly storm- and/or tide-related scour event. This inference
is supported by the appearance of an erosional scour and deflection in the 1927 shoreline
shown in yellow on Figure 6 (below). The inferred rail line also appears to have been disrupted
by the 1927 scour event. This rail-line likely facilitated transport of raw materials (rip rap,
cement, aggregate, concrete, etc.) to and from the Jetty during construction, and may have
been supported by materials of similar character.

Beach near the site expanded southward by approximately 230± feet between 1927 and 1935, and an
additional 300± feet between 1935 and 1942. This expansion appears to coincide with the extension of
the Newport Harbor Jetty by as much as approximately 600± feet, forming the “Wedge” of Balboa Beach.

Early to Middle Historic Development (1932-1942)
Development throughout Balboa Peninsula (in the form of Balboa Avenue, intersecting cross-
streets, and sparse residential construction) is apparent as early as 1932. In 1935 (Figure 7,
below), development of Balboa Peninsula overall appears to have been underway, with various
cross-streets, side streets, and residential housing in place along Balboa Avenue. However,
development near the site, at the end of the newly established peninsula, appears to be limited.
By 1935, the shoreline nearest the project site appears to have expanded southward by
approximately 230± feet relative to 1927, creating at least part of the land that currently supports
the site / existing residence. Subsequent topographic mapping available from 1942 indicates
that the overall shoreline had expanded an additional 300± feet (Figures 6, above; Figure 8,
below) and became established relative to its modern configuration. An additional factor in
establishing the modern shoreline and local vicinity of Balboa Beach near the Wedge is the
inferred placement of dredged sand to raise the elevation of the beach fronting the rear of the
project site, elevating it as much as 8± feet higher (El. 18-19± feet) relative to other areas
throughout Balboa’s main stretch to the northwest, commonly at El. 10-11± feet NAVD 88.

Early to Middle Historic / Modern (1948-Present)
An air photo from 1948 (Figure 9, below) indicates that the site itself was originally developed
and occupied by previous a residence that has since been demolished and replaced by the
existing residence onsite (Figure 10, below). Based on our discussions with the current owners
and limited review of vintage architectural plans for the existing residence, it is our
understanding that demolition of the previous residence and replacement with the existing
residence took place in the early 1980s. In terms of shoreline development and change, the
1948 air photo appears to show the site during a constructional phase of shoreline development
that took place in May of that year. Comparison of the modern shoreline configuration with that
shown in Figure 9 indicates that the shoreline may have prograded / expanded southward by as
much as 100± feet in that season relative to the modern shoreline shown in Figure 10. In
general, the modern shoreline is understood to be relatively stable, but subject to similar
advances and retreats driven by astronomical tides, storm activity, man-made influences, and
general fluctuations in sediment load. The Wedge itself has formed within the groin of the
Newport Harbor Jetty, representing a zone of accumulation which is stabilized by longshore

Local Geologic Units and Occurrence
According to geologic mapping by Morton and Miller (Reference No. 2; Figure 11, attached), the
site is shown as being underlain by Quaternary very young eolian deposits (Qe) and Quaternary
very young marine deposits (Qm) of late Holocene age. The eolian deposits are described as
being comprised of unconsolidated / fine-grained sand and silt derived from recently active,
coastal sand dune deposits occurring in the Newport Beach area; the marine deposits are
described as, “unconsolidated, active or recently active sandy beach deposits along coast”. In
general, for the purposes of this study, native sediments underlying the site are designated as
Quaternary beach sand (Qb), representing a combination of native eolian and marine deposits.
These soils intermingle with shallow / locally-derived / undifferentiated fills of similar character.
Fill soils, where present, likely occur in the upper 3-5 feet and are generally similar to / reworked
from the local native beach sands.
The deposits directly underlying the site to depths of approximately 15-20± feet below ground
surface are understood to be historic, quasi-natural deposits of littoral sand and possible dredge
fills established during the early 1900’s during the development and expansion of Balboa
Peninsula and the Newport Harbor Jetty. An additional 5-6± feet of historic fills and/or native
eolian deposits are present at the rear of the property, accounting for the 5-6± feet higher
elevation difference between the north and south sides of the property and alleyway /
beachfront, respectively. Below these historic deposits are similar marine deposits of littoral
sand and shell hash deposited during the early to middle Holocene and perhaps latest
Pleistocene (when sea level was significantly lower), extending to depths of at least 50 feet.
GEOTECHNICAL INVESTIGATION
Field and Laboratory Investigation
On June 18, 2021, two (2) hand-auger borings (HA-1 and HA-2) were advanced through a
corehole in the existing garage slab and rear planter located at the southwest corner of the
property, respectively. Subsequently, on June 21, 2021, three exploratory borings (B-1 through
B-3) were drilled to refusal at depths of approximately 14 feet below the existing driveway using
a limited-access, track-mounted, hollow-stem auger drilling rig. An additional series of borings
(B-4 through B-9) were advanced through coreholes in the garage slab, living room slab, and
rear patio using a limited-access, solid-stem tripod rig. Soil samples were obtained at selected
depths and transported to the laboratory for testing. Laboratory testing was performed on
representative soil samples obtained during the field exploration to determine geotechnical
properties of the site’s subsurface materials.
A temporary monitoring well was installed in Boring B-4 and generally consisted of 2-inch-
diameter solid and slotted Sch 40 PVC well casing, No. 3 sand filter pack, bentonite annular
seal, and 8-inch well cover.
The logs of our geotechnical borings and monitoring well construction are included in
Appendix A. Laboratory test results are included in Appendix B. Boring locations are shown on
the attached Figures 2 and 3 (attached).

Existing Subsurface Conditions
Quaternary Beach Sand (Qb) and Historic / Locally-Derived Fill (Undifferentiated)
Based on the findings of our subsurface exploration and local experience, soils underlying the
site are predominately sandy and are assigned herein as being representative of Quaternary
beach sand (Qb) and undifferentiated, historic / locally-derived fills of similar character. In
general, soils encountered in B-1 through B-9 consisted of historic / locally-derived /
undifferentiated fill soils underlain by Quaternary beach sand grading from loose to medium-
dense within approximately 10-15± feet of the surface and medium-dense to dense below. Our
local experience indicates that native soils generally become dense to very dense at depths
below approximately 20-25 feet. The sands are predominantly quartz-rich, fine- to medium-
grained, subrounded to subangular, and poorly-graded, containing local concentrations of
coarse sand and/or sea shell fragments. Groundwater was initially encountered in B-1, B-2, and
B-3 at depths of approximately 7.5± feet below ground surface or El. 6± feet above NAVD 88.
Zone of Inferred / Buried Rip Rap
As shown on Figures 2 and 3 and described in Appendix A, an apparent zone of buried rip rap
was encountered in Borings B-1, B-2, and B-3. This zone of inferred rip rap precluded further
advancement of our borings and occurred beginning approximately between 11 and 14 feet
below the existing driveway surface or between approximately Elevation -1 and +2 feet above
NAVD 88. As described in the Surficial Geology / Geomorphology / Site History section of this
report, this zone of inferred rip rap is interpreted as being representative of early-1900s era,
imported rip rap used to construct the nearby Newport Harbor Jetty (the “Jetty”), local rail line,
and/or possibly a local revetment used to stabilize the shoreline following storm activity and
scour apparent in 1927.
Samples obtained from the zone of rip rap encountered in B-1/B-2 consisted of cemented
chunks of concrete / Portland cement, sand, fine to coarse gravel, and cobbles. In B-3, a drive
sample obtained at about 14 feet consisted of intact, medium-grained, very hard / “fresh”
granitic rock. Visual assessment indicates that the sample obtained was likely diorite to quartz
diorite in composition with approximately 40-50 percent (%) mafic mineral grains (likely
amphibole and minor biotite, with or without pyroxene). The sample was also noted to be
equigranular, containing white to translucent / euhedral plagioclase with possible minor quartz
and amphibole / biotite with or without pyroxene. In terms of its general character, the rock
sample is consistent with abrasion-resistant, boulder-sized rip rap that would have likely been
used around 1927 to construct the Jetty, rail line, and/or temporary revetment.
As illustrated on Figure 2, the exact size / extent of the rip rap is currently unknown, but borings
B-4 through B-7, B-8, and B-9 were drilled to depths of 30 feet, 25 feet, and 15 feet,
respectively, without refusal; borings HA-1 and HA-2 were advanced to depths of approximately
5.3 feet and 10.5 feet without refusal, implying the absence of subsurface rip rap throughout the
southeasterly two-thirds of the property. Based on review and analysis of the 1927 air photo
shown on Figure 6, depth / elevation at which the rip rap was encountered (below mean sea

level and near the level of mean lower low water – i.e., El. -1 to +2 NAVD 88), and distance
offshore between the site and 1927 shoreline (estimated at 40-50 feet), it is inferred that this
zone of rip rap is either a localized condition (perhaps placed by accident), represents the
southernmost extent of a temporary / historic revetment, and/or collapsed material associated
with the historic rail line and 1927 scour event. Rip rap may occur at other locations / depths not
explored.
HYDROGEOLOGY / GROUNDWATER
General Hydrogeologic Overview
Soils underlying the site are understood to consist of Quaternary-age beach sand to depths of at
least 50 feet or more, with groundwater occurring at depths of approximately 4-13± feet below
existing site grades. Groundwater is unconfined and understood to be essentially salty (saline)
ocean water. Based on previous subsurface investigations for the site and other neighboring
sites, there are understood to be no confining layers (aquicludes / aquitards) below the site to a
depth of at least 50 feet. Groundwater below the site is understood to be in open-
communication – vertically, horizontally, locally, and regionally – with the Pacific Ocean and
Newport Harbor. This communication is facilitated by the presence of relatively continuous, sub-
horizontally layered, moderate- to high-permeability, fine- to medium-grained and locally coarse-
grained sand horizons / lenses that comprise the native soils of Balboa Peninsula.
Groundwater Levels / Fluctuations
Tidal fluctuations of the Pacific Ocean and Newport Harbor affect groundwater levels by
inducing hydraulic gradients toward the ocean/harbor and away from the site during low tide
conditions, and away from the ocean/harbor and toward the site during high tide conditions. Our
recent groundwater monitoring for the period of June 21st, 2021 through December 10th, 2021
indicates that groundwater elevations range between approximately +4.5 to +6.7 feet
(NAVD 88) following low-low tide (e.g., -1.2 feet) and high-high tide conditions (e.g., +6.0 feet),
respectfully. However, actual groundwater levels may vary slightly from these estimates due to,
among other things, apparent changes caused by barometric pressure variations over the
monitoring period, which can introduce errors generally on the order of no more than about
0.1 feet and not more than about 0.3-0.4 feet (the upper bound range of variability in
atmospheric pressure over the entire monitoring period). A graph summarizing our observations
and recorded water levels over the monitoring period is attached as Figure 12 and we note that
our manual water level readings were within 0.1 feet of the water levels predicted based on the
transducer data, tied to the different manual readings. For planning purposes, water levels may
be expected to vary between approximately +5 and +7 feet above NAVD 88 – conservatively
accounting for possible measurement errors caused by barometric pressure variations which
would affect the transducer data. It should also be noted that these estimates are based on
limited data obtained during the above referenced monitoring period and actual levels may
occur outside the range reported. Nonetheless, the estimates provided herein are considered
reasonable relative to the available data and intended use.

SEISMIC HAZARDS
General
Seismic hazards are typically categorized into two hazard classes, primary and secondary.
Primary seismic hazards are those directly related to a seismic event and include surface
rupture and strong ground motion due to regional earthquakes / fault lines. Secondary seismic
hazards are functions of the primary hazards and include responses of the local ground to
seismic shaking from liquefaction, lateral spreading, earthquake-induced landslides, etc.
Additional hazards associated with coastal settings and open water bodies include tsunamis
and seiche. Risks to the project site and proposed development associated with these
earthquake-related hazards are described below.
Surface Rupture and Strong Ground Motion
There are no known active fault traces mapped across the project site and the site is not located
in an Earthquake Fault Zone of Required Investigations. The nearest zoned active fault is
located approximately 7 miles northwesterly of the subject site. However, as shown on
Figure 13 (attached), the site is located approximately 0.85 miles northeast of the offshore,
“presumed active” North Branch of the Newport-Inglewood Fault Zone (NIFZ) designated by the
City of Newport Beach. Another “presumed active” splay of the NIFZ is also mapped offshore
approximately 0.57 miles south of the site. For the purposes of this study, we consider these
strands of the NIFZ potentially active and capable of producing localized ground cracking and/or
displacement of the relatively young, Holocene-age sediments that encompass the local
offshore region. Onshore, the NIFZ is shown intercepting Balboa Avenue approximately 2 miles
west-northwest of the project site, implying that disruption of major utility and transportation
corridors is also possible during a major earthquake / rupture event along the NIFZ. However,
with regards to the site itself, onsite effects would likely be limited to far-field deformation (e.g.,
uplift, subsidence, translation, etc.). In general, risk of onsite, fault-related ground rupture is
considered unlikely and potential risks related to offsite ground rupture include disruption of
utilities and transportation routes intersecting active strands of the NIFZ.
Strong ground motion as a result regional seismic activity will undoubtedly occur in the future
and affect the project site via seismic shaking. The Newport-Inglewood Fault is the nearest
active fault and believed to be the causative fault in the 1933 magnitude (Mw) 6.4 Long Beach
Earthquake which reportedly caused severe ground shaking (Modified Mercalli Intensity VIII)
and moderate to heavy damage to structures in the local area according to the California
Department of Conservation (https://www.conservation.ca.gov/cgs/earthquakes/long-beach),
based on the work of Barrows (1970, Reference 3), Trifunac (2003, Reference 4), and others.
Risks associated with seismic shaking and strong ground motion are considered moderate to
high but can be mitigated / reduced through appropriate geotechnical / structural design and
construction practices. Seismic design parameters based on ASCE 7-16 are included in
Appendix C.

Newport Beach, California
Liquefaction and Lateral Spread
Liquefaction is a phenomenon in which saturated, cohesionless or low-cohesion soils
temporarily lose shear strength during relatively severe earthquake ground motions.
Liquefaction has potential to adversely affect buildings, utilities, roads and other man-made
structures due to a loss of foundation support during the event. In general, saturated /
predominately granular soils tend to compact and decrease in volume when subjected to strong
ground motion, resulting in an increase in pore water pressure if drainage is impeded. If the
pore water pressure becomes equivalent to the overburden pressure, the effective stress
becomes zero and, consequently, the soil loses its strength and is considered to be in a
liquefied state. Factors known to influence the potential for liquefaction include soil type and
depth, grain-size, relative density, groundwater level, degree of saturation, and both the
intensity and duration of ground shaking.
According to the California Geological Survey’s web-based application (EQ Zapp), the site is
located in a liquefaction hazards zone of required investigations. The subject site is underlain by
sandy materials, shallow groundwater, and is in an area of high seismic exposure resulting from
large earthquakes on the Newport-Inglewood Fault Zone and other regional fault lines. Based
on USGS Seismic Hazard data, a site-modified peak ground acceleration (PGAm) of 0.722 g,
factored deterministic acceleration value (PGAd) of 1.056 g, and a maximum earthquake
magnitude of 7.5 (no magnitude scaling factor applied) were used in our analysis. Liquefaction
analyses and assessment for the project site took into account the SPT blow count data
recorded during the field exploration drilling, soil profile / ring densities, highest anticipated
groundwater levels, review of available geotechnical reports in the vicinity of the site, and
computerized analyses based on the methodology presented by Seed and Idriss.
Based on the results of liquefaction analysis, and our local experience with other nearby sites
along the peninsula, potential dynamic settlement for the existing site soil conditions under a
major seismic event could be on the order of approximately 2-3 inches occurring in the upper
15-20 feet. These dynamic settlements are expected to occur over a large area. Liquefaction
analysis is included in Appendix D.
Lateral Spread
Lateral spreading is defined as the finite lateral displacement of gently sloping ground as a
result of pore pressure build-up / liquefaction in a shallow underlying deposit during an
earthquake. Liquefaction induced lateral spreading under a major seismic event can also occur
for nearly level ground sites with a free-face condition (e.g., channel or harbor). In general, the
degree of / potential for lateral spreading decreases with distance away from free-face / sloping
conditions. Confining layers with low permeability can increase the potential for liquefaction if
they impede subsurface drainage / pore pressure dissipation of underlying, saturated sand
layers with lower relative density.
Based on available subsurface information and interpretation of the site’s geomorphology, the
potential for adverse lateral spreading occurring at the site is considered relatively low

Newport Beach, California
compared to other areas within and around Newport Harbor. The site is located 1,000± feet
westerly of Newport Harbor and its inlet / outlet channel, and 415± feet inland of the Pacific
coastline; groundwater occurs within approximately 4-13 feet of the surface; and there is
potential for liquefaction occurring at relatively shallow depth. However, the local area is
relatively flat-lying and appears to occupy the quasi-natural / post-development portions of
Balboa Peninsula which were essentially grown as part of the Wedge by accumulation of littoral
sand and placement of rip rap and dredged sand to construct the rear elevated portions of the
beach south of the site. It is worth noting that Barrows (1970, Reference 3), in his review of
reported “surface effects” associated with the 1933 Mw 6.4 Long Beach earthquake, made no
references to liquefaction / lateral spreading occurring along Balboa Peninsula. Nonetheless,
the potential for liquefaction / lateral spreading cannot be ruled out, making it a low to moderate
risk associated with the site / vicinity, particularly in association with larger magnitude
earthquakes on the NIFZ. Potential effects may include localized ground lurching / minor lateral
displacements as a result of acute liquefaction phenomena (e.g., sand boiling) at shallow depth,
distributed over a large area.
Earthquake-Induced Landslides
Review of published geologic mapping and the California Geological Survey’s web-based
application (EQ Zapp) indicates that the subject site is not identified as being in an earthquake-
induced landslide hazard zone. The site itself is flat-lying and there are no slopes nearby which
would be considered susceptible to any meaningful instability that would affect the site.
Considering the above, the potential for earthquake-induced landsliding affecting the site is
considered nil.
Tsunami
Topographic and regional maps indicate the subject site is approximately 415± feet inland of the
Pacific Ocean and 1,000± feet westerly of Newport Harbor. The site sits at an estimated
elevation of 13-18± feet above NAVD 88 and the Tsunami Inundation Map for Emergency
Planning, Newport Beach Quadrangle, prepared by the California Emergency Management
Agency, California Geological Survey, and University of Southern California (2009, Reference 5)
indicates that the site is within an area identified as having the potential for tsunami inundation
under a major seismic event occurring in the adjacent offshore region as result of local faulting,
submarine landsliding, and/or more distal, subduction-related faulting around the pacific rim.
Based on the above, there is potential risk of inundation due to a tsunami event from known
sources in the Pacific Ocean.
Seiche
Seiche is defined as a standing wave oscillation effect generated in a closed or semi-closed
body of water caused by wind, tidal current, and/or earthquake. Seiche potential is highest in
large, deep, steep-sided reservoirs or water bodies. The site is not near any significant pools,
lakes, reservoirs, or similar, is 1,000± feet from Newport Harbor and 415± feet inland of the

Newport Beach, California
Pacific Ocean. Given that, the potential risk of seiche-related effects from existing water bodies
is considered low.
COASTAL FLOODING HAZARDS
In general, coastal flooding hazards can occur in association with astronomical high tides and/or
exceptional storm events which can overwhelm storm drains and cause localized flooding as a
result. Given that, the project site may be prone to localized flooding during such events and this
should be accounted for in design and construction.
Coastal flooding hazards specific to the site in association with sea level rise, wave run up, and
shoreline change are addressed under separate cover as part of our forthcoming coastal
hazards report for the project.
HYDROGEOLOGIC HAZARDS AND CONSIDERATIONS
Overview
Site excavations will extend approximately 9-14 feet below existing site grades and
approximately 1 to 3 feet below the water table – which varies as a result of tidal fluctuations
that occur over periods on the order of 3-5 hours and up to about 9 hours or more, with long-
term fluctuations occurring based on lunar tides (i.e., spring and neap tides occurring throughout
the month) and perigean tides (occurring 3-4 times throughout the year). With regards to
temporary site dewatering, the secant pile / DSM program is intended to cement the sands into
nearly impervious soilcrete to minimum depths of 23-38 feet below existing ground surface,
eliminating the need for site dewatering. However, local imperfections in the cement treatment
may conduct groundwater and may require secondary treatment by the ground improvement
contractor. The potential groundwater intrusion and other potential hazards will increase as
overburden is removed and excavations progress further below the water table / potentiometric
surface of hydrostatic head. Hydrogeologic hazards considered herein include the potential for
buoyant uplift, seepage forces, and soil piping. Our evaluation of these hazards is described in
further detail below.
Buoyancy / Uplift / Heave
Buoyancy can cause uplift / heaving of excavation bottoms when hydrostatic head pressure
(uplift) exceeds the weight of overburden (soil cover). The proposed soilcrete subgrade
materials are estimated to achieve a dry unit soil weight of approximately 100 pounds per cubic
foot (pcf), while the unit weight of seawater is approximately 64 pcf – this means that 6.4 feet of
overburden (soilcrete cover) is required to resist 10 feet of hydrostatic head pressure (uplift) for
a factor of safety of 1, and any uplift pressure exceeding that would theoretically cause the
excavation bottom to heave. Given the currently planned depths of excavation (1 to 3 feet below
the water table) and planned minimum soilcrete thickness below the excavation bottom
(14 feet), temporary factor of safety against uplift relative to the proposed rough grade pad
elevation (+4.00 feet) is estimated at about 1.29 (assuming hypothetical high water table
elevation of +7 feet). To maintain a factor of safety of 1.25 against buoyant uplift, approximately

PA2022-0167

Proposed New Residence Construction Project No. 1-1201
2050 East Oceanfront Page 19 of 39
Newport Beach, California
13.6 feet of soilcrete cover would need to be maintained. Note that these factor of safety
estimates are conservatively based on one-dimensional, instantaneous values that would only
develop if the excavation overburden were removed instantaneously. Actual factors of safety
would increase significantly when accounting for staging / timing of the excavation work relative
to astronomical tides and related groundwater fluctuations, 3-dimensional effects associated
with the geometry of the excavation, thickness of the secant piles / adjoining overburden, and
friction between the secant piles and adjacent soil outside the excavation. Additional overburden
imparted by the perimeter secant piles and cohesion afforded by cementation of the soilcrete
are also mitigating factors in resisting buoyant uplift.
Seepage Forces and Uplift
Seepage forces, with regards to the above, are additional uplift forces that can develop as a
result of vertical / upward groundwater seepage. Seepage forces can be viewed as frictional
dragging forces between flowing groundwater and soil particles calculated as the product of
hydraulic gradient (feet of head loss per unit distance) and unit weight of seawater (64 pcf). In
the context of the scenarios describe above, vertical hydraulic gradients that may develop as a
result of groundwater seepage / underflow through hypothetical imperfections in the soilcrete
(assuming a +7 feet hypothetical high water table elevation) could approach a theoretical /
instantaneous vertical gradient of 0.21 feet/foot (ft/ft) at the planned +4.00 feet pad elevation.
Given that, estimated seepage forces on the order of 13.4 pcf would be expected (assuming a
theoretical worst case of +7 feet groundwater elevation and one-dimensional / instantaneous
removal of overburden in absence of dewatering). With respect to the proposed soilcrete / DSM
program, seepage would generally occur through localized imperfections in the soilcrete and
impart forces on the overburden (pervious sand seams) that can uplift and dislodge soil particles
near the surface of the excavation.
Seepage Forces and Soil Piping
Soil piping is a phenomenon caused by steep hydraulic gradients and high rates of groundwater
seepage. As described above, groundwater seepage imparts a drag force (seepage force) on
the soil media through which it permeates. When groundwater seepage exits a free-face, soil
particles nearest the face can be mobilized if the hydraulic gradients / seepage forces exceed a
certain threshold. In the case of groundwater seepage through vertical or near-vertical,
hypothetical seams / pipes of uncemented sand occurring in the planned soilcrete prism, soil
piping is a significant hazard that can cause uncemented sands to mobilize near the surface of
the excavation and erode internally downward as material continues to be displaced by seepage
/ groundwater flow. Uncontrolled seepage / soil piping can also cause rates of seepage to
increase as material is displaced and made less restrictive to flow.
The theoretical basis and methods of evaluating the potential for / magnitude of soil piping are
relatively complex. A common criterion used is the ratio of submerged unit weight of the soil in
question and unit weight of water – which yields the critical hydraulic gradient at which soil
piping could potentially occur. In the case of residual, uncemented, hypothetical sand seams /
pipes, using the submerged unit weight of soilcrete (36 pcf - similar to that anticipated for native

Newport Beach, California
sands below the site), divided by the unit weight of seawater (64 pcf), yields a critical hydraulic
gradient of 0.56 feet per foot (ft/ft). Based on an estimated hydraulic gradient of 0.21 ft/ft, factor
of safety against soil piping for the proposed temporary excavations (assuming there were any
continuous / throughgoing imperfections in the soilcrete) is estimated at 2.7 – a conservative
estimates based on high-groundwater conditions and the presence of hypothetical, through-
going sand seams.
GEOTECHNICAL CONSIDERATIONS
The major geotechnical factors that should be considered during project design include the
following:
1. Presence of relatively loose sands occurring in the shallow subsurface and saturated
sands / groundwater at general depths of 4-13± feet below ground surface – site
dewatering would be required for a conventional remedial grading scheme. However, the
remedial grading efforts currently planned will include the use of secant piles and deep
soil mixing (soilcrete). Based on previous discussions with design-build ground
improvement contractors for the soilcrete, dewatering will not be required.
2. Potential soil disturbance resulting from the demolition of the existing residence and
ancillary elements.
3. Static settlement due to foundation / improvement loading and dynamic settlement
resulting from earthquake-induced liquefaction and shallow dry sand settlement.
4. Below-grade excavations required to facilitate subterranean level construction proximal
to adjacent property lines and below existing groundwater levels – requiring appropriate
shoring, waterproofing, and ground stabilization during and following construction.
5. High ground accelerations / seismic shaking may be experienced at the site as a result
of local and/or regional earthquakes during its design life – therefore, the proposed
structures should be designed and constructed to the prevailing standards and seismic
design requirements.
6. The potential presence of buried rip rap within the proposed secant pile / soilcrete prism,
requiring post-demolition exploration and screening to verify clearance.
7. Corrosion potential due to the local environment / coastal setting.
8. Engineering geologic considerations including the potential for shallow groundwater,
coastal flooding, and other hydrogeologic hazards.
9. Soil exposure issues related to control of external influences on the structure – including
water / moisture / vapor, vegetation (landscaping), soil chemistry (i.e. sulfate / pH /
corrosivity issues), exposure to rain, weather, and coastal environment.

RECOMMENDATIONS
General
Based on the findings obtained during our field exploration phase, results of laboratory testing,
and our understanding of the currently proposed new residential structure, it is our opinion that
the proposed construction is feasible from a geotechnical standpoint, provided that the
recommendations included herein and City of Newport Beach grading requirements are
incorporated in the design and implemented during construction.
Secant Piles / Deep Soil Mixing and Site Dewatering
The major geotechnical earthwork challenges from a constructability standpoint are the
excavation, shoring, and site dewatering aspects for the planned subterranean level when
considering off-site property constraints. To facilitate planned excavations for the subterranean
level of construction as well as minimize site dewatering efforts and potential adverse
settlement / subsidence effects to off-site development, a secant pile / deep soil mixing (DSM)
program has been recommended. This secant pile / DSM program will include reinforced
shoring system along property lines and provide in-situ ground improvement to mitigate
potential adverse effects due to soil liquefaction. With regards to temporary site dewatering, the
secant pile / DSM program is also intended to eliminate the need for site dewatering.
A general description of the secant pile / DSM program is provided in the Project Description
section of this report and plans and supporting documents will be provided under separate
cover by others.
Pre-Construction Documentation / Vibration Monitoring / Survey Monitoring
The planned construction is to include heavy equipment operations, drilling / deep soil mixing,
shoring installation along property line, and other related activities with the potential to generate
significant noise, ground vibration, and other effects which may be perceived as potentially
adverse. In order to mitigate potential issues related to noise, vibration, shoring installation, etc.,
a monitoring and mitigation program should be developed and implemented in advance of and
during the planned construction activities. As a minimum, the monitoring and mitigation program
should include the following components:
Pre-Construction Documentation – The site and neighboring properties (interior and
exterior portions) should be photo-documented in advance of the planned construction to
provide a baseline for pre-construction conditions and for comparison purposes during
and post-construction. G3 can provide these services under separate cover.
Pre-Construction Noise / Vibration Monitoring – Noise and vibration monitoring should
be performed in advance of the planned construction to establish normal levels of
background noise / vibration. These background levels should be documented and
“safe” thresholds should be established for in-construction noise and vibration
monitoring. G3 can provide these services and additional criteria under separate cover.

Proposed New Residence Construction Project No. 1-1201
2050 East Oceanfront Page 22 of 39
Newport Beach, California
In-Construction Noise / Vibration Monitoring – Noise and vibrations should be monitored
during construction and regulated in accordance with established “safe” thresholds for
residential construction. A minimum three monitoring stations (two stationary, one
floating) should be established during construction to provide adequate coverage near
adjacent properties and ensure that vibration levels do not exceed established
thresholds. G3 can provide these services and additional criteria under separate cover.
Survey Monitoring – The planned secant pile shoring system should be monitored for
deflection / movement via survey of dedicated benchmarks established at the regular
intervals along property line. Baseline readings should be established prior to the start of
any excavation work and surveyed at regular intervals following. For planning purposes,
weekly surveys should be conducted by a licensed / qualified surveyor to ensure that the
pile deflections do not exceed established regulatory thresholds (i.e., not to exceed
½-inch). Additional criteria for this work can be provided under separate cover.
Potential Buried Rip Rap and Post-Demolition Verification
As shown on Figure 2 and described herein, a zone of inferred / buried rip rap was encountered
below the existing driveway. The exact size and extent of this rip rap zone is currently unknown
and may occur within the limits of the proposed secant pile / soilcrete prism. In order to verify
clearance for the proposed secant pile / DSM soilcrete columns, the ground improvement
contractor should perform their own due diligence subsurface exploration following demolition of
the above-grade portions of the existing residence to verify sufficient clearance between the
soilcrete and potential buried rip rap. This may require the advancement of supplemental
borings near the driveway and throughout the property and/or possibly the use of other
geophysical methods, following demolition when the site can be accessed by conventional
equipment. If rip rap is encountered during the post-demolition phase, design modifications may
be required.
Considerations for Existing Retaining Walls and Property Line Shoring Installation
As shown on Figure 2, there are existing retaining walls at the rear of the garage and within
approximately 3 feet of property line. Demolition of these existing retaining walls and installation
of the proposed secant piles will need to be carefully coordinated so that excavation sidewalls
remain supported. Due to the presence of cohesionless sands, excavation sidewalls should not
go unsupported along property. G3 can provide input on means and methods of the contractor
upon request.
Grading
In general, initial earthwork / grading would generally be limited to demolition / removal of the
existing residence and improvements and preparation of the existing site surface to provide
support for the DSM equipment. Excavation for planned subterranean construction is planned
following the installation of secant piles and DSM ground improvement program, with temporary
access ramp cut along the northern side of the subterranean level to facilitate access.

2050 East Oceanfront Page 23 of 39
Newport Beach, California
Remaining grading would generally be limited to foundation excavation observations, retaining
wall and utility line backfill placement and compaction, and precise grading for drainage.
Presented below are general grading recommendations relative to site clearing, preparation,
excavation, etc. which should be included as part of grading operations, as appropriate.
Site Clearing and Preparation
a) Site preparation and grading should be made under the observation of the Project
Geotechnical Consultant or their representative.
b) Proper measures should be implemented during the performance of remedial / precise
grading work to protect the work site, particularly excavated areas, from flooding,
ponding and inundation due to poor or improper temporary surface drainage. During
periods of impending inclement weather, temporary provisions should be made to
adequately direct surface drainage, from all sources, away from and off the work site
and to provide adequate pumps and sumps to handle any flow into the excavations.
c) Prior to the start of the required earthwork and grading, all vegetation, surface trash,
debris and other deleterious materials should be removed from areas of planned grading
and wasted away from the site. Vegetation removal should include root-balls and
attendant root systems.
d) Utility laterals / stub outs should also be located prior to grading and flagged.
e) Any pipelines or conduits encountered within the zone of planned development that are
designated for abandonment should be removed from the construction area and ends
cut and plugged according to the applicable Code requirements but not less than 10 feet
outside the perimeter of the proposed construction area, or as property line
considerations dictate. Non-reinforced concrete or clay pipes may be crushed in-place
and incorporated in the fill.
f) Alternately, deep hollow lines may be left in place, provided they are filled with concrete.
No filled line should be permitted closer than 2 feet from the bottom of footings.
g) Local ordinances relative to abandonment of underground utilities, if more restrictive, will
supersede the above minimum requirements.
Temporary Shoring
Secant piles are proposed to provide temporary shoring for subterranean level construction.
Presented below are geotechnical criteria for use in secant pile design.
Lateral Earth Pressures
For secant wall design, the following lateral earth pressures (equivalent fluid pressures) are
recommended as a minimum:
At-Rest Earth Pressure (*) : 60 pcf
At-Rest Earth Pressure (**): 92 pcf

(*) At-rest earth pressure above potential high groundwater levels.
(**) At-rest earth pressure including hydrostatic pressure conditions below high
groundwater.
The above lateral earth pressures apply to vertical walls and level backfill conditions. Surcharge
load effects from existing and anticipated loads (e.g., structures, construction loading and
vehicle traffic / parking) should be included in design.
Secant Pile and Deep Soil Mixing – Quality Assurance / Quality Control
A program of Quality Assurance / Quality Control (QA/QC) for the planned secant pile and deep
soil mixing program should be established by the project’s Ground Improvement Design-Build
Contractor. G3 can provide additional input and collaboration as needed under separate cover
to assist the ground improvement contractor in developing and implementing appropriate
QA/QC protocols prior to and during construction. G3 can also provide third-party testing
services and observations / testing during construction to appropriately document the subject
work and provide input / additional recommendations as needed. It is the responsibility of the
contractor performing the work to ensure that work is performed in accordance with the project
plans / specifications and the intent of the recommendations provided herein.
Excavation Procedures
Temporary excavations in untreated site soils 4 feet or deeper should be shored or sloped in
accordance with Cal OSHA requirements. Special construction techniques, such as slot cutting,
may be utilized if excavations are greater than 4 feet vertical and site constraints preclude use
of temporary slope cuts.
For subterranean level excavations made within the soilcrete mass, excavation slopes may be
made at a 3/4:1 (H:V) gradient.
Excavations located along property lines and adjacent to the reinforced secant shoring systems
may be made vertical. Care should be taken when excavating along the secant wall to prevent
the peeling of soilcrete soil layers – patching or grinding of the exposed excavation face may be
necessary to provide a working surface to apply blindside waterproofing, where applicable.
A representative of this firm should be present on-site during excavations to verify acceptability
of temporary slopes. Acceptability will be dependent upon the soil conditions encountered,
excavation depths, construction procedures, and schedule.
During site excavation operations and construction, the secant walls should be periodically
survey monitored to verify acceptability of the shoring system and enable our office to evaluate
need for additional recommendations, as appropriate.
Testing and Observations
Site preparation, grading, compaction, and backfill operations should be performed under the
observation and testing of the Project Geotechnical Consultant. As appropriate, an adequate

Newport Beach, California
number of field tests should be performed to verify compliance with recommendations
presented in this report and local ordinances.
If it is determined during grading that site soils require over-excavation to greater depths for
proper structural support, this additional work should be performed in accordance with the
recommendations of the Project Geotechnical Consultant.
Fill materials should be compacted to the minimum 90 percent relative compaction based on the
laboratory maximum density determined in accordance with ASTM: D1557.
Foundation Recommendations
General
Presented below are preliminary recommendations for the construction of mat slab foundation
systems for residence support and alternative shallow conventional footings for the at grade
level of construction when support into and on soilcrete.
Mat Foundation Design
The proposed residence may be supported on mat foundation bearing on approved soilcrete. A
mat foundation distributes structural load across the structure footprint, resulting in more uniform
applied pressures to the bearing stratum. The contact pressure distribution beneath the mat is a
function of foundation rigidity and the type of bearing material.
As indicated in the Project Description section, a preliminary 30-inch-thick mat slab, 3-inch
waste slab, and 3-inch protection slab (reinforcement per Structural Engineer and input from
waterproofing manufacturer) is proposed below the proposed basement with associated
retaining walls. The following geotechnical criteria may be used in the design of mat foundation
system founded on the DSM mix for support of the planned residential structure:
Allowable Bearing Pressure (1) = 3,000 psf
Coefficient of Sub-grade Reaction = 100 pci
Mat thickness = Per Structural Engineer
Passive Soil Pressure (2) = 300 psf/ft.
Friction Coefficient = 0.3 (ultimate)
(1) Bearing pressure in shear only for mat foundation supported on soilcrete
(DSM) and may be increased by one-third to resist transient loads such
as wind or seismic.
(2) Passive soil pressure value is for level soil grades adjacent to foundation,
with a maximum value not to exceed 2,000 psf.
(b) The structural details of the mat foundation such as thickness, reinforcements,
concrete strength, etc. should be established by the Project Structural Engineer,

Proposed New Residence Construction Project No. 1-1201
2050 East Oceanfront Page 26 of 39
Newport Beach, California
considering the loading and service conditions. The mat should be adequately
reinforced based on structural design considerations and/or Code requirements.
(c) Foundation excavations should be observed and approved by the Project
Geologist and Geotechnical Engineer prior to the placement of reinforcement or
concrete.
(d) The mat foundation should be designed to resist both temporary hydrostatic
conditions which may develop during construction and post-construction
hydrostatic conditions which may develop over the project’s intended design life,
considering both temporary in-construction and permanent post-construction
foundation loading and hydrostatic uplift pressures.
(e) The mat foundation should be appropriately moisture / water-proofed, as
recommended hereinafter (Refer to forthcoming Technical Memorandum –
Hydrogeologic Evaluation Findings and Dewatering Plan Recommendations for
additional information regarding proposed shallow dewatering system under slab
and related subgrade preparation).
(f) Pad subgrade is to be overlain by 4-inch-thick layer of ¾-inch crushed aggregate,
in turn, overlain by Mirafi 140N (double-layer; second layer cross-lapped relative
to first; 18-inch min. lapping for all fabric).
(g) A 3-inch-thick waste slab (f’c = 4,500 psi min., w:c = 0.45, Xypex) is to be poured
on top of 4-inch thick gravel layer and Mirafi 140N to provide flat / smooth surface
for waterproofing installation.
(h) An additional 3-inch protection slab (f’c = 4,500 psi min., w:c = 0.45, Xypex) is to
be poured on top of waterproofing once installation is complete to protect
waterproofing during rebar installation and mat slab pour.
(i) Mat slab (f’c = 5,000 psi min., w:c = 0.4, Xypex, per Project Structural Engineer)
to be poured directly on top of protection slab.
Conventional Footing Design Criteria
Presented below are preliminary recommendations for the construction of shallow conventional
footings for the at-grade level of construction when supported on approved soilcrete mix.
Allowable Bearing Pressure (1) = 3,000 psf.
Minimum Footing Depth (2) = 18 inches
Minimum Footing Width = Per 2019 CBC
Passive Soil Pressure (3) = 300 psf/ft., subject to a maximum of 2,000
psf.
Friction Coefficient = 0.30 (ultimate)
Minimum Footing Reinforcement = For continuous footings, min. four No. 4

Newport Beach, California
bars, two at top and two at bottom.
(1) Allowable bearing pressures may be increased by one-third for short-term
loading due to wind or seismic forces.
(2) Footing depth is below lowest adjacent soil grade. Footings should be
deepened, as necessary, to depth equivalent to existing adjacent
foundations.
(3) Passive soil pressure value is for level soil conditions adjacent to footings.
Ancillary Wall Footing Criteria
Shallow conventional footings may be considered for ancillary structures (e.g., free-standing
screen walls, etc.) located outside the limits of the soilcrete (DSM) mass, when incorporating
additional reinforcing to resist potential differential settlement and provide redundancy to
account for potential temporary loss in foundation support under potential liquefaction
conditions. A strengthened conventional foundation system would help to mitigate, but not
eliminate, temporary loss of foundation support and wall distress due to soil liquefaction. The
following criteria may be used in design for these ancillary foundations, when underlain by
minimum of 2 feet of engineered compacted fill and extending laterally at least 2 feet beyond the
footing edges.
Allowable Bearing Pressure (1) = 1,000 psf.
Minimum Footing Depth (2) = 24 inches
Minimum Footing Width = Per 2019 CBC
Passive Soil Pressure (3) = 150 psf/ft., subject to a maximum of 1,500
psf.
Friction Coefficient = 0.30 (ultimate)
Minimum Footing Reinforcement = For continuous footings, min. four No. 4
bars, two at top and two at bottom.
General Foundation Remarks
(i) Footing embedment depths should be maintained throughout the life of the
structure, and not compromised via erosion softening, digging, landscaping, etc.
(ii) Where foundations encroach closer than five (5) feet horizontally from the flow
line of drainage swales or percolation features, the footings edges should be
deepened sufficiently to maintain the required embedment depth below the
adjacent flow line.
(iii) Foundation details such as concrete strength, reinforcements, thickness, etc.
should be established by the Project Structural Engineer, considering the loading
conditions. The recommended foundation embedment, thickness and
reinforcements are minimum requirements and should be established by the
Project Structural Engineer. More restrictive criteria based on structural design

considerations or Code requirements shall govern.
(iv) Foundation excavations should be observed and approved by the Project
Geotechnical Engineer prior to the placement of reinforcement or concrete.
Forming of footing excavations may be required. Excavations should be free of
slough and debris and thoroughly moisture conditioned prior to placing concrete.
(v) Excavated material from footing and utility trenches should not be placed in slab-
on-grade areas unless properly compacted and tested.
(vi) Isolated pad footings should be structurally tied in at least two orthogonal
directions.
(vii) Footings should be doweled to the existing floor slab with No. 4 bars at 18 inches
on center.
(viii) Floor slab-on-grade should be underlain by a moisture vapor retarder, as
recommended hereinafter, to mitigate moisture / water vapor intrusion into the
structure.
Settlement
Some structure movement should be expected both during and following construction, even
when supported on engineered compacted fill, due to various factors including, but not limited
to:
Sequence of foundation and slab loading during construction;
Variation in structural loads along foundation elements;
Variation in underlying soil types with different compressibility indices and subsurface
soil profile, and associated primary and long-term secondary consolidation settlements;
and
Moisture changes and groundwater due to climatic and non-climatic influences following
construction.
It should also be recognized that given residential construction tolerances, concrete floor slabs
will not be cast perfectly level, and it has been our experience that floors slab elevations may
vary by as much as an inch or more.
For design purposes and considering the above factors, total settlements for new structure
foundations designed and constructed in accordance with the above criteria and supporting
loads not exceeding the typical loadings for residential construction are not expected to exceed
1-inch. Potential differential settlements for foundations / slabs are not expected to exceed 1/2
inches across a distance of 30 feet.
Ancillary footings located outside the soilcrete zone should be designed to accommodate
potential total and differential settlements, under static plus seismic conditions, on the order of
3 inches and 1.5 inches in about a 30 feet distance, respectively.

Retaining Wall Criteria
Presented below are lateral earth pressures for the use in design of the subterranean / inset
level walls for the planned residence.
Lateral Earth Pressures
The earth pressure acting on retaining walls depends primarily on the allowable wall movement,
type of backfill materials, backfill slopes, wall inclination, surcharges, and any hydrostatic
pressure. For inset subterranean level walls, wall movement necessary to develop active earth
pressure conditions will not occur and therefore these walls should be considered restrained.
The following lateral earth pressures (equivalent fluid pressures) are recommended for the
design of basement / restrained walls:
At Rest Earth Pressure (*): 60 pcf
At-Rest Earth Pressure (**): 92 pcf
Seismic Pressure Increment: 23 pcf
(*) At-rest earth pressure for that portion of retaining wall extending below
highest estimated coastal flooding elevation per the Coastal Hazards Report
for the project.
(**) At-rest earth pressure including hydrostatic pressure forces.
The above lateral earth pressures apply to vertical walls and level backfill conditions. Surcharge
load effects from existing and anticipated loads (e.g., structures, construction loading and
vehicle traffic / parking) should be included in design.
Retaining Wall Backdrainage / Waterproofing
Retaining walls should be adequately waterproofed and incorporate a wall backdrainage system
during construction to relieve potential hydrostatic pressure buildup behind walls. Preliminary
recommendations for retaining wall backdrainage are presented in the Site Drainage / Wall
Backdrainage section of this report.
Wall Backfill
Backfill materials behind walls should consist of predominantly granular, free draining material,
and compacted to at least 90 percent relative compaction and near optimum moisture contents.
For planning purposes, crushed miscellaneous base is recommended for subterranean level
retaining wall backfill. However, we reserve the right to modify our recommendations, as
appropriate.
Wall Backdrainage
Wall backdrainage recommendations specific to the proposed development can be provided by
our office, in coordination with the Project Civil Engineer / waterproofing contractor /
manufacturer, as the project evolves and during subsequent plan review phases.

Newport Beach, California
Seismic Design Considerations
The site, as is all of Southern California, is within a zone of seismic activity. Strong ground
motion from an earthquake generated along active faults should therefore be anticipated at this
site. The proposed residence should be designed and constructed to the prevailing standards
regarding seismic design. Seismic design should be based on current and applicable CBC
requirements, as appropriate. Seismic design parameters based on ASCE 7-16 are included in
Appendix C.
Concrete Slab and Exterior Flatwork
The concrete slab design and construction details should be established by the Project Design
Engineer. From a geotechnical standpoint, the minimum criteria for slab-on grade are shown
below:
a) Concrete Driveway
Concrete floor slabs should be 6 inches thick (minimum) and should be reinforced with
No. 4 bars at 12 inches on center, each way at mid height, and should be structurally
tied to the footings. Considerations should be given to providing grade beam
connections, keyed at regular intervals into the underlying soilcrete. Additional
recommendations for driveway construction can be provided at the plan review stage of
the project.
b) Exterior Flatwork
Sidewalks, walkways and patio slabs should be 4 inches thick (minimum) and should be
reinforced with No. 3 bars at 18 inches on center, each way at mid height.
c) Slab Sub-Grade Compaction and Pre-saturation (Exterior Flatwork)
Prior to concrete placement, the prepared soil sub-grade should be moisture conditioned
to and maintained at about 1 to 3 percentage points wet of optimum moisture contents to
a depth of 12 inches and exhibit at least 90 percent relative compaction as determined
by ASTM: D1557 or as otherwise specifically recommended by the Project Geotechnical
Consultant of record based on actual conditions.
d) General Concrete Remarks
To minimize slab curling and other related adverse effects, a low shrinkage / low
slump concrete (concrete mix with a minimum 4,500 psi compressive strength and
maximum water cement ratio of 0.45) should be used for the floor slab construction,
as determined by the Project Structural Engineer. The mix design should be verified
by the project Civil / Structural Engineer, and placement of concrete should be
observed and certified by the Concrete Deputy Inspector.

2050 East Oceanfront Page 31 of 39
Newport Beach, California
Interior floor slabs and exterior concrete flatwork should be properly designed for the
construction and service loading conditions, and potential differential movements.
The structural details, such as slab thickness, concrete strength, reinforcing criteria,
joint spacing, etc. should be established by the Project Civil / Structural Engineer.
The recommended minimum reinforcements for concrete slabs provided above are
intended for preliminary design only. More restrictive criteria as dictated by structural
design or regulatory requirements shall govern.
All reinforcement must be appropriately spaced and supported / maintained during
the pouring / finishing work such that it remains in proper condition.
Unless specifically allowed for and approved as such by the project Civil / Structural
Engineer, no water is to be added to the concrete mix after the truck leaves the plant.
It should be cautioned that addition of water to the concrete mix will change the
water-cement ratio of the plant design mix and can lead to undesirable shrinkage
cracking, curling, etc. of concrete slabs during curing.
All concrete to be properly finished per American Concrete Institution / Portland
Cement Association standards and moist cured (for preferably at least 7 days). If
moist curing is not feasible, an appropriate curing compound / sealant should be
applied in accordance with the timing and methodology specified by the curing
compound manufacturer.
Truck tickets to include mix design, time leaving plant, time of site arrival, and time
onsite / location of pour to be documented and copies sent to the project Civil /
Structural Engineer.
All poured concrete should be protected from loading and traffic for at least 7 days
without written approval of the project Structural engineer.
Waterproofing and Moisture / Water Vapor Retarder System
General
The following are key considerations which must be kept in mind when addressing inset level
construction / foundation elements below grade which are sensitive to water / moisture / vapor.
In our general experience, both from a design / build and a forensic standpoint, a large
percentage of subterranean construction suffers from distress ranging from the all too common
“musty odors” / dampness, floor and wall covering damage and debonding, to free water
intrusion and wall / slab cracking and heaving. Understanding the role and behavior of water –
in its multiple forms of occurrence – is a critical step in the proper addressing and mitigation of
nuisance and damage to subterranean foundation elements:
Water is the root driving mechanism controlling both expansion and related ground
activity and moisture intrusion related distress.
Water is insidious and will inevitably find its way into places it is not desired.

Proposed New Residence Construction Project No. 1-1201
2050 East Oceanfront Page 32 of 39
Newport Beach, California
Water buildup in the shallow subsurface over the life of the project is inevitable in the
case of projects such as this.
Water can exist and simultaneously co-exist / transform into multiple phases of
occurrence: liquid / hydrostatic, capillarity, and vapor.
The flow and migration of water is controlled by free energy gradients, which include
gravity, suction / capillarity, salinity, humidity, temperature, and others.
A major free energy gradient which drives water transmission through foundations into
structures is the combination of humidity and temperature, and differences in humidity
and temperature between the ground and interior spaces. Water, particularly as vapor,
will tend to flow from areas of high humidity and temperature towards areas of lower
humidity and temperature. This condition is created by atmospheric environment,
particularly where air conditioning is used, forming a gradient of high humidity and
temperature in the underslab subgrade environment and the typically much lower
humidity and cooler environment in the interior space.
The humidity, under equilibrium, in the subsurface including the void spaces of soil, rock,
gravel, drains, pipes, cavities, vaults, and other features is typically at or near 100%
relative humidity. It only takes a small drop in temperature for condensation to develop,
which may accumulate faster than it can dissipate – particularly where humidity remains
nearly 100% and temperature changes are small. A similar condition will occur under low
permeability floor coverings – creating a major form of flooring distress and damage.
Capillarity, in particular where it interphases with vapor, is a very difficult to control
phase, as it involves wicking like through a paper towel. Even a tiny imperfection can
quickly grow a large downstream “wet spot” where it is controlled solely by a membrane
or sheeting / coating.
Since capillarity is controlled by the hydrophilic (“water-loving / attracting”) chemistry of a
substance, the use of a concrete mix unattractive to water in subterranean level
construction will further mitigate the moisture vapor transmission and wet-spotting. Thus,
the use of proven hydrophobic additives should be considered for use in all foundation
members in contact with and/or below grade that will support / enclose living areas.
The different phases of water require their own separate forms of mitigation – hydrostatic
/ free water drainage or barriers (especially those relying on clay or “bentonite” sheeting
or layers) will not stop capillarity or vapor; and mitigation measures to control vapor are
not very effective at hydrostatic water control. Even then, the concrete itself should be
made as watertight as possible.

Newport Beach, California
A major key to success is to recognize that multiple systems must be incorporated in proper
tandem to control all forms of water. Another key to success is to recognize that even with the
best construction practice; some imperfections are inevitable and will be capitalized on by water.
Waterproofing – Subterranean Level
Floor slab and wall waterproofing should effectively mitigate free water, capillary water,
and water vapor into the inset level of construction and should be installed in
conformance with manufacturer’s recommendations to resist full hydrostatic pressures
that may develop during and post-construction.
Inset level slab construction and walls should be waterproofed to effectively mitigate free
water, capillary water, and water vapor into the sublevel and should be installed in
conformance with manufacturer’s recommendations to resist full hydrostatic pressures
that may develop during and post-construction.
As an added measure to mitigate potential water / moisture vapor transmission into
subterranean level construction, we recommend incorporating a hydrophobic admixture
(Hycrete W1000, Xypex, or architect / structural engineer approved equivalent) in the
concrete. This hydrophobic mixture should be considered for both the basement floor
slab and subterranean structure walls. Considerations may also be made to
incorporating hydrophobic admixture to secant pile walls.
Dedicated waterstops and epoxy concrete bonding agents installed / applied according
to manufacturer recommendations are required at all joints and between pours.
A dedicated waterproofing membrane (e.g., Miraply) should included as part of the
waterproofing system for the mat slab and retaining walls and installed in accordance
with the manufacturer’s recommendations to resist full hydrostatic pressures that may
develop during and post-construction.
All waterproofing membranes (including Miraclay products) should be rated for service in
contact with seawater and approved by the manufacturer as part of the overall design
and installation.
As appropriate and/or required by the manufacturer, waterproofing membranes should
be protected by dedicated drainboard / protection board (e.g., Miradrain 6200 XL)
installed in accordance with the manufacturer’s specifications for below-grade, vertical
applications, with potential for full-hydrostatic conditions.
Miraclay should not be installed in direct contract with concrete to mitigate transmission
of capillary water into subterranean floor slab / retaining wall concrete.
Waterproofing design and installation for the project is to be performed by a qualified
waterproofing contractor (e.g., American Product Coatings) with oversight from the
product manufacturer (Carlisle Coatings and Waterproofing). A representative of the
manufacturer should be retained to provide inspection services during waterproofing

installation and verify that waterproofing specifications and installation criteria are
appropriately met during construction. (Note: G3 does not inspect or approve
waterproofing specifications or installation – waterproofing specifications and installation
for the project are under the purview of the waterproofing contractor and manufacturer’s
representative).
Moisture Water Vapor Retarder System
A moisture vapor retarder is recommended to reduce the potential for moisture / water vapor
migration up through the slabs constructed at grade and possibly affecting floor covering.
Presented below are recommendations based on the guidelines by the American Concrete
Institute (ACI) to reduce the potential moisture / water vapor intrusion in concrete slab-on-grade:
The moisture / water vapor retarder should consist of high strength membrane and should
meet or exceed the ASTM: E-1745-97 Class A material requirements for water vapor
permeance, tensile strength, and puncture resistance. The vapor retarder should consist
of “Stego Wrap 15-mil” (Stego Industries, LLC) or “Vapor Block” VB 15 (Americover, Inc.),
or approved equal. The vapor retarder should be underlain by a capillary break comprised
of minimum 4 inches thick pea gravel layer. The gravel layer should be placed and
compacted on approved soil sub-grade.
The membrane should be placed on approved gravel layer and properly lapped and
sealed. Protection of this membrane from punctures / tears is critically important.
Membranes intersecting utility pipes, sewer lines, ducts, or drains must be properly
wrapped around the penetrations and sealed. All punctures and rips in the membrane
should be repaired prior to placement of concrete, following manufacturer’s
recommendations. The vapor retarder should be installed in general accordance with the
procedures outlined in ASTM: E-1643, and in conformance with the installation
procedures recommended by the manufacturer.
In addition, floor coverings (e.g., wood, tile, etc.) and other built-in features should be
carefully selected with vapor transmission in mind and include proper preparation and
installation in accordance with the manufacturer’s recommendations.
Additional recommendations / specifications may be provide by the waterproofing
contractor and manufacturer.
It should be recognized that, even with site surface and sub-drainage measures, there is
potential for saturation of ground beneath concrete floor slabs due to water infiltration from
irrigation, rain, and run-off, and adverse moisture / vapor development or flow through the soil
subgrade. The upward migration of moisture in vapor phase from soil subgrade through the
slab-on-grade is inevitable under normal living conditions as they exist within a closed
environment (e.g., structure). It is imperative that the Contractor properly install the
recommended site drainage measures, utility trench backfill, and the moisture/water vapor

Newport Beach, California
retarder system in accordance with the project design requirements and specifications to
mitigate potential moisture / water vapor transmission into the structures.
It should be emphasized that proper moisture / water vapor retarder installation, proper control
of irrigation, surface runoff, roof drainage, and landscape water adjacent to the structure is very
important to minimize problems caused by moisture and water vapor intrusion and is the
responsibility of the property owner. In addition, the property owner is responsible for
maintaining proper site drainage as recommended hereinafter.
Expansive Soils
The near surface site soils underlying the subject site are comprised of poorly-graded sands,
and these soils are expected to exhibit a very low soil expansion potential, and not considered a
controlling factor in foundation design. The soil expansion potential should be verified during or
at the completion of rough grading operations.
Soil Corrosion and Concrete Design
Soluble Sulfates
Laboratory test results presented in Appendix B indicate sulfate exposure for concrete is Not
Applicable (negligible) – however, in consideration of the project location within a coastal
environment, it is recommended that concrete in contact with soils be designed to resist
potentially high sulfate exposure (i.e., Type V Portland Cement, minimum compressive strength
of 4,500 psi, and maximum w:c = 0.45).
Metallic Installations
Laboratory tests to evaluate the potential soil corrosivity to metallic installations were not
performed. In the absence of such testing, the soils along with any transient waters flowing
through them should be considered to be highly corrosive to metals in contact with them.
Attention to minimizing galvanic / chemical corrosivity (i.e., protective coatings, dielectric
couplings, eliminating mixing metal types in contact or in near vicinity to each other) where in
contact with soil and soil moisture can minimize these effects. An experienced corrosion
consultant should be retained and their recommendations incorporated into the design if special
/ critical corrosive issues exist or further corrosion potential study is warranted.
Utility Trench Backfill
Bedding material should consist of sandy material exhibiting a Sand Equivalent (S.E.) value of
30 or greater and should comply with the requirements of the controlling governing jurisdiction.
The on-site soils are not considered suitable for use as bedding material.
The site soils are considered suitable for trench backfill, provided they are free of organic
material and rocks over 4 inches in maximum dimension.
Backfill of all exterior and interior trenches should be placed in thin lifts of appropriate thickness
and mechanically compacted to achieve a relative compaction of not less than 90 percent

throughout, based on ASTM: D1557. Care should be taken not to damage utility lines during
compaction.
Utility trenches should not be located within the influence of footings. This is defined as a zone
located below the footing and a line sloping at an inclination of 1:1 (horizontal to vertical)
outward from the outside edge of footings. If utility lines are located within the zone of footings,
the backfill should be compacted to a minimum 95 percent relative compaction or slurry
backfilled (minimum 1-1/2 sack cement-sand mix).
Trenches greater than 4 feet in depth should be shored or sloped back as required by the local
regulatory agency, the State of California Division of Industrial Safety Construction Safety
Orders, and Federal OSHA requirements.
Utility trench points of connection / entryways into the residence should be appropriately sealed
and cut-off to prevent moisture / free-water intrusion into the structure.
Site Drainage
It should be noted that potential problems may develop when drainage is altered through
construction of retaining walls, paved walkways, and patios. Conditions which will lead to
ground saturation must be avoided:
All roof and surface drainage should be directed away from structures and their appurtenances
to approved drainage facilities. Ponding of water should be avoided. For graded soil areas, a
minimum gradient of 5 percent away from structures should be maintained.
The recommended drainage patterns should be established at the time of fine grading and
maintained throughout the life of the structure or, if altered, should be replaced with a properly
designed area drain system.
Irrigation activities at the site should be monitored and controlled to prevent over-watering.
Planter areas adjacent to structures should be avoided. If utilized, such planters should include
measures to contain irrigation water and prevent moisture migration into walls and under
foundations and slabs-on-grade.
Site drainage should also be designed, constructed, and maintained in accordance with
appropriate City, County, State, and other jurisdictional requirements.
Landscape, Irrigation and Maintenance
General guidelines for landscape, irrigation and maintenance are shown below:
Landscape planting should consist of appropriate drought resistant vegetation as
recommended by the Landscape Architect. Landscape irrigation should minimize soil
moisture variation and should be properly maintained.
Trees / large shrubs with aggressive root systems should be avoided near structures
and slopes.

The property owner is responsible for proper irrigation and for maintenance and repair of
installed irrigation systems. Leaks should be repaired immediately. Sprinklers should be
adjusted to provide maximum coverage with a minimum of water usage and overlap.
Over-watering with consequent excessive runoff and ground saturation must be avoided.
If automatic sprinkler systems are installed, their use must be adjusted to account for
natural rainfall conditions.
All interceptor ditches, drainage terraces, down-drains, and any other drainage devices
that are installed must be maintained and cleaned.
Water must not be allowed to flow over constructed or natural slopes. This may require
the construction of berms or ditches along the top of slopes, if such devices are not in
place.
With regard to foundation and slab / pavement performance adjacent to landscape
areas, a key to maximum performance is landscaping and irrigation which minimizes soil
moisture fluctuation over time. Avoiding saturation and ponding is also an important
consideration. Diligent attention to maintenance is critical to adequate long-term
performance.
Plan Review, Observations, and Testing
There are numerous geotechnical and engineering geologic conditions, phenomena, and issues
present that will have considerable influence on the design, construction, and long-term
performance of the proposed development. Therefore, it is considered of high importance and
prudence that this firm be retained throughout the design and construction process to provide
appropriate geotechnical and geologic support, input, review, and documentation services to
assist the design and construction team with accounting for these issues appropriately. It is
critical that the geotechnical and engineering geologic recommendations be properly taken into
account and understood by the parties involved, and the intent of the recommendations properly
incorporated into the final design, construction, and long-term maintenance of the project. Major
milestones / areas of applicability include:
Foundation and Grading Plan Reviews;
Secant Pile Installation and Deep Soil Mixing;
Earthwork, Grading, and Subterranean Excavations;
Subterranean level waterproofing installation and mat slab / retaining wall construction;
and
Subsurface / Underground Utilities Installation.
It is the responsibility of the owner / developer to ensure the findings of our studies and intents
of our recommendations are forwarded to the appropriate consultants and contractors of the
project – and that they are incorporated into the final plans and construction. This report and the
recommendations provided in this report should be considered a part of the project plans /
specifications.

LIMITATIONS
This report has been prepared for the exclusive use of Mr. Scott Schwartz and his design
consultants relative to the design and construction of the proposed new residence. This report is
not intended for other parties, and it may not contain sufficient information for other purposes.
This report and the recommendations confirmed herein are made with the understanding that
G3SoilWorks will be appropriately retained to assist with the design and construction team in
proper interpretation, incorporation, and implementation of the intent of our report
recommendations. Should a different firm be retained to perform the subsequent phases of
design and construction, this report will be considered null and void.
The Owner or their representative should make sure that the information and preliminary
recommendations presented in this report are brought to the attention of the Project Architect,
Project Civil, Project Structural Engineer, Project Ground Improvement Design Engineer and
made part of the project plans. It is the responsibility of the contractor performing to ensure that
the subject work is performed in accordance with the project plans / specifications and intent of
the recommendations provided herein as part of the final construction.
This office should be provided with final grading, ground improvement, and foundation plans for
review to enable us to confirm the preliminary recommendations and update the report as
necessary. We reserve the right to modify our recommendations, as appropriate, to better
accommodate actual conditions and/or means and methods employed by the contractor
performing the work.
The findings contained in this report are based upon our evaluation and interpretation of the
information obtained from limited borings and the results of the laboratory testing and
engineering analysis. The opinions and recommendations provided were based on the
assumption that the geotechnical conditions, which exist across the site, are similar to those
observed in the test excavations. The conditions and characteristics of the sub-surface
materials at locations and depth other than those excavated and observed may be different and
no representations are made as to their quality and engineering properties. Based on our
experience with similar sites, some variability and unanticipated conditions may be present, and
some degree of "as-grading" is anticipated to be warranted to appropriately address these
conditions and to meet the intent of the recommendations presented herein. As such, many of
the overexcavation, embedment, and replacement issues, based on actual exposed conditions,
may be at odds with the generalized considerations made herein. These issues and conditions
should be appropriately evaluated / addressed by this firm on a case-by-case basis at the time
the work is performed – and the resulting recommendations and refinements reported in a final
as-graded report documenting the geotechnical aspects of the project work.
Should any conditions encountered during construction differ from those described herein, this
office should be contacted immediately for evaluation of the actual conditions and for
appropriate recommendations prior to continuation of work.

LABORATORY TEST PROCEDURES AND RESULTS
The samples obtained during the field investigation were transported to the laboratory for testing
and analysis. The results of tests performed on selected samples and the test procedures are
summarized below.
Dry Density and Moisture Content
Field dry density and moisture contents of undisturbed soils samples retained in 2 3/8–inch
inside diameter by one-inch height rings were determined, and moisture test results were
obtained for the small bulk samples. Dry density and moisture content testing were performed in
accordance with ASTM D2937 and ASTM D2216, respectively. The test results are posted on
the Geotechnical Boring Logs in Appendix A.
Maximum Dry Density and Optimum Moisture Content
Maximum dry density and optimum moisture content test was performed on the submitted bulk
soil samples in accordance with ASTM: D 1557. The results are shown below:

200 Wash Sieve Analysis
A 200 Wash Sieve test was performed on the requested soil sample in accordance with ASTM
D1140 to determine the percentage of material finer than the No. 200 sieve. The test result is
shown below.

Direct Shear
Direct shear tests were performed on representative, relatively undisturbed soil samples with a
direct shear machine of the strain-controlled type in which the rate of strain is 0.01 inches per
minute. The soil specimens were soaked in a confined state prior to shearing and were sheared
under varied normal loads ranging from 1.0 ksf to 4.0 ksf. The test results are plotted on Figures
S-1 to S-3.
Consolidation
Consolidation tests were performed on samples identified as HA-2 @ 3.5 feet and B-3 @ 12.5
feet. The test specimen was initially loaded to 0.2 tons per square foot and soaked at 0.8 tons
per square foot. Progressive loading was then applied to a maximum of 3.2 tons per square
foot. Loading was then reduced to determine rebound characteristics. The consolidation tests
are presented on Figures C-1 and C-2.

Liquefaction Analysis Assumptions
Seismic settlement analyses for the subject property were performed using LiquefyPro (Version
5.9a) computer program developed by CivilTech Software based on the soil profiles, SPT /
converted Mod Cal blow counts, and laboratory data obtained during our investigation.
The following design earthquake parameters were considered in these analyses:
•Magnitude (M) = 7.5
•Modified peak horizontal ground acceleration (PGAM) = 0.722g (no magnitude scaling
factor)
•Deterministic peak horizontal ground acceleration (PGAD) = 1.056
•Historic high groundwater depth of 3 feet below ground surface according to the Seismic
Hazard Zone Report for the Anaheim and Newport Beach 7.5-Minute Quadrangles. To
account for elevation differences between the front and rear of the property (approximately
13.3 feet and 18.73 feet, respectively), a groundwater elevation of 10.3 feet (or a depth of
3 feet and 8.4 feet for the front and rear of the property, respectively) was used in these
analyses.
The results of these liquefaction analyses are attached in this Appendix D.
