Attention: Mr. James R. Devlin
SUBJECT: REPORT OF GEOTECHNICAL INVESTIGATION AND UPDATE
Aviara Planning Area 15
Carlsbad, California
Gentlemen:
The following report presents the findings, conclusions, and recommendations of the geotechnical
investigation of the previously graded subject site. In general, our findings indicate that the
alluvium within the site is generally wet and dense, and has a low potential for collapse. There
were no unusual or special geotechnical conditions apparent in our investigation which would
preclude the construction as planned. Proposed grading will create local areas of transitions
between cut and fill that should be treated to reduce the potential for differential settlement. A
fill proposed for the southeast corner of the site will create a surcharge on the underlying
alluvium. Construction in that area may be subject to some delay while consolidation occurs in
the alluvium.
1.0 PURPOSE AND SCOPE OF WORK
The purpose of our investigation was to evaluate existing conditions at the site as they relate to
the proposed residential construction, and to make recommendations regarding foundation design
parameters and site preparation. The recommendations contained herein are based on a surface
reconnaissance, laboratory testing, and professional experience in the general sitearea. Design
values may include presumptive parameters based on professional judgement. Our scope of
work was limited to:

1.1 A review of the available geotechnical reports and geologic literature, site
development plans, and aerial photographs of the site and immediate vicinity. A 40-scale
map of the site "Substantial Conformance Exhibit 'A", prepared by Lundstrom and
Associates was used as abase map for Plate 1, Geotechnical Map.
1.2 A geologicreconnaissance of the surface characteristics of the site.
1.3 A subsurface investigation consisting of the drilling of two exploratory borings with an
eight inch diameter flight auger. The subsurface investigation focused on characterizing
the behavior of the alluvium left in place beneath the fill.
1.4 Laboratory testing of samples collected in the field in order to assess the
compressibility and collapse potential of the alluvium.
1.5 Engineering analysis of field and laboratory data in order to develop our conclusions
And recommendations. 11
1.6 Preparation of this report as well as subsequent reviews of foundation and grading
plans.
2.0 SITE DESCRIPTION
The subject site consists of Aviara Planning Area 15, located in Carlsbad, California. Planning
Area 15 was graded between April 20 and November 15, 1989 as a portion of Unit E of the
Aviara Development. Our reconnaissance of February 6, 1996 indicated that the site appears to
be at the same grade as originally constructed. The site consists of a rough graded pad bound
on west and south by 2:1 (horizontal to vertical) descending fill slopes, to the east by natural
ascending slopes, and to the north by composite ascending natural and cut slopes. Surface
drainage is by sheet flow and concrete lined ditch southward into a large desilting basin. The pad
is accessed by Black Rail Court. The site configuration is presented in the Geotechnical Map,
Plate 1.
The pad has undergone erosion since grading in 1989. A prominent north-south trending erosion
gully up.to 6-feet deep is present in the center of the pad. The main, gully has several tributary
drainages. The gully empties into the desilting basin.

3.0 PROPOSED DEVELOPMENT
The proposed development will consist of 16 multifamily, single- and two-story buildings will be
built on fine graded pads. There will be between 3 and 4 units per structure. 'Paved streets will
provide access. Grading will consist generally of cuts in the southern portion of the site and filling
the northern portion to create level pads for the buildings. Slopes up to 25 feet high are proposed
at inclinatiobs of 2:1.
4.0 GEOTECHNICAL CONDITIONS
Based on our investigation and literature review, the site, is underlain by' fill,' alluvium, Torrey
Sandstone, 'and Ardath Shale. 'The approximate extent of each of these units has been
delineated previously on the As-Graded Geotechnical Maps, which have-.been adapted for use
in this report as the Geotechnical Map, Plate 1. The ,estimated subsurface conditions of the
southern portion of the site are shown on Figure 1, Cross Section A-A'. A description of the
specific units observed during drilling follows.
4.1 Torrey Sandstone (TO
The site is underlain at depth by Torrey Sandstone materials. The formational material,
as observed on site, consists of a light yellow brown, fine to medium grained, poorly
graded sandstone 'with silt (SP-S,M) which is dry to moist, and dense. This material is
nonpiastic, and exhibits little or no expansive, potential.
4.2 Ardath Shale (Ta)
The Ardath Shale is exposed in the northeast corner of the site and consists of sandy to
silty claystone and siltstone. Grading for access roads and erosion debris have covered
this formation. During the original grading of the site and in other locations within the
Aviara subdivision, the Ardath Shale was found to be moderately to highly expansive. The
expansive soil conditions created by the Ardath Shale will only affect Units 1-3.

4.3 4.3.1 Alluvium (Qal)
During grading of PA 15 in.1989, loose dry alluvium was removed to moist dense soil prior
to placement of flu. Alluvium was encountered immediately overlying the Torrey
Sandstone in both exploratory borings (Plate 1). Alluvium materials, as observed on site,
typically consist of a light.brown silty sand (SM) or a sand with silt (SP-SM) which is moist
to very moist, -and medium dense.
4.4 Fill
Fill material was encountered in both borings to a depth of up tb 37 feet. The composition
of the fill material varied from a fine to medium grained silty to a clayey sand (SM to SC).
The fill was moist, medium dense, and had a low plasticity. Observation and testing of
fill placement was conducted by ICG, Inc. and reported in 1990 (References).
4.5 Groundwater and Seepage
No seepage or groundwater was observed during our investigation. However,
groundwater may become perched at any elevation within the Soils due to poor surface
drainage, irrigation, seasonal rainfall, or a combination of these factors. Based on our
observations, it is likely that groundwater could become perched at the interface which
exists between the alluvium and the Torrey Sandstone. This should not, however, affect
the proposed development.
5.0 GEOLOGIC HAZARDS AND SEISMICITY
5.1 Geologic Hazards
The subject site is not located within an area previously known for geologic hazards, nor
was evidence of past faulting noted in our investigation.
5.2 Seismicity and Faulting
The subject site is located approximately 5.0 miles northeast of the projected offshore
trace of the Rose Canyon fault zone. This fault zone is classified as active, and capable
of generating a magnitude 6.4 earthquake (maximum Probable event). The estimated

peak site ground acceleration for such an event is 0.42g. Design of structures should
comply with the requirements of the governing jurisdictions, building codes and standard
practices of the Association of Structural Engineers of California. Ground-breaking due
to active faulting is considered to have a low potential, due to the distance from known
active fault traces.
6.0 CONCLUSIONS
No geotechnical conditions were apparent during the investigation which would preclude
construction of the propoSed subdivision as planned. The as-graded geotechnical conditions
described in the referenced report remain applicable to the site. However, some geotechnical
'factors were observed in our investigation which will need to be addressed.
Our laboratory analysis indicates that the existing alluvium on site has a very low collapse
potential. Based on observations made during grading, as well as our professional
experience with similar materials, it appears as though primary consolidation 'of the
alluvium is completed. However, secondary compression of the alluvium may still occur,
resulting in relatively minor broad settlements.
The site contains deep fill. It has our experience that even well documented compacted
fills may undergo hydrocompression on the order of 0.2 percent of the fill height. This
may result in moderate differential settlements across the length of the proposed
structures. The potential for damage resulting from such movement should be mitigated
through the use of post-tensioned slab foundations, and thickened and reinforced exterior
slabs and sidewalks.
A proposed fill in the southeast corner of the site (Unit 31) will apply an additional
surcharge to the underlying alluvium. This will trigger primary consolidation in the alluvium
and may result in settlement to the newly graded surface. Additionally, settlement may
cause deflection of pipelines within the easement. .
The on-site soils include both medium dense fill, and dense to very dense sandstone.
The proposed development may therefore result in cut/fill transitions within building pad
areas. Transitions from sandstone to fill below foundations and slabs are not
recommended due to the different settlement characteristics of the materials, and the

7.2.1 General: General site preparation should consist of the removal of all
deleterious material from within any areas to be developed. Deleterious materials
should be removed from the site, and legally disposed. Deleterious material
includes vegetative debris, topsoil, and construction debris.
7.2.2 Building Pads: Within the entire building pad area, deleterious material
should be removed as discussed above, and the remaining loose .surficial
materials should be scarified to a depth of one foot. The Scarified soil should then
be compacted in accordance with the recommendations given in Section 7.4.
Structures should not be constructed over cut/fill transitions. In areas where a
cut/fill transition will exist beneath a structure, we recommend that the cut portion.
of a building pad be over-excavated, and then brought back to finish grade with
compacted fill. Overexcavation for cut/fill transitions should be performed to a
depth of H/2, where.H is defined as the greatest depth of fill underlying the pad.
Expansive soil should be removed to a depth of 5 feet below Units 1-3 and be
replaced with nonexpansive soil.
7.2.3 Debris Basin: A temporary debris basin was installed during rough grading
in the southern corner of the site. Soft sediments have accumulated within the
basin since initial construction. All soft sediments within the basin should be
removed to a depth where competent material is encountered. The entire
excavation should then be brought up to finish surface grade with compacted fill
as discussed in Section 7.4. In the event that the existing storm drain pipes within
the 'debris basin are to be abandoned, they should be removed and their
excavations backfilled with compacted fill in accordance with Section 7.4.
7.2.4 Erosion Gullies: Soft sediments within the erosion gullies should be
removed to a depth at which competent material is encountered. The gullies
should then be brought up to plan grade with compacted fill in accordance with
Section 7.4.

7.3 Excavation and Grading Observation
Foundation or other site excavations should be observed by Geotechnics Incorporated.
Such observations are considered essential to identify field conditions that differ from
those anticipated by the preliminary investigation, and to adjust designs to actual field
conditions. Recommendations presented in this report are contingent upon Geotechnics
Incorporated performing such services.
7.4 Fill Compaction
All fill and backfill to be placed in association with site development should be accom-
plished at slightly over optimum moisture conditions and using equipment that is capable
of producing a uniformly compacted product. The. minimum relative compaction
recommended for fill is 90 percent of maximum density based on ASTM D1557. Sufficient
observation and testing should be performed by Geotechnics Incorporated so that an
opinion can be rendered as to the compaction. achieved.
Imported fill sources, if needed, should be observed prior to hauling onto the site to
determine the suitability for use. Representative samples of imported materials and on
site soils should be tested. by the geotechnical consultant in order to evaluate their
appropriate engineering properties for the planned use. Imported soils should have an
expansion index of 20 or less.
7.5 Site Drainage
Foundation and slab performance depends greatly on how well the runoff waters drain
from the site. This is true both during construction and over the entire life of the structure.
The ground surface around structures should be graded so that water flows rapidly away
from the structures without ponding. The surface gradient needed to achieve this depends
on the prevailing landscape. In general, we recommend that pavement and lawn areas
within five feet of buildings slope away at gradients of at least two percent. Densely
vegetated areas should have minimum gradients of at least five percent away from
buildings in the first five feet. Densely vegetated areas are considered those in which the
planting type and spacing is such that the flow of water is impeded.

Planters should be built so that water from them will not seep into the foundation, slab,
or pavement areas. Site irrigation should be limited to the minimum necessary to sustain
landscapingplants. Should excessive irrigation, surface water intrusion, water line breaks,
or unusually high rainfall occur, saturated zones or "perched" groundwater may develop
in the underlying soils or bedrock. The residence should be constructed with rain gutters
which intercept all roof runoff. Rain gutters should be kept clear of debris. The rain
gutters should outlet .to drain lines, which in turn outlet directly to the curb or storm drain.
All surface flatwork should be serviced by area drains. Area drains shOuld have a fall of
at least 1%, and should outlet to a suitable curb or storm drain system.
7.6 Foundation Recommendations
These recommendations are.considered generally consistent with methods typically used
in southern California. Other alternatives may be available. The foundation
recommendations herein should not be considered to preclude more restrictive criteria of
governing agencies or by the structural engineer. The design of. the foundation system
should be performed by the project structural engineer,. incorporating the geotechnical
pararheters described in the following sections.
The following recommendations assume that grading operations are performed as
discussed in Section 7.2. Shallow foundations should be suitable for structures founded
entirely on fill (Units 1-25, 39-51). Post-tensioned slab foundations should be used for
structures founded on fill underlain by alluvium (Units 26-38).
7.6.1 Shallow Foundations on Fill. Units 1-25 and 39-51
Allowable Soil Bearing: [Osf (allow a one-third increase for short-term
(wind reismic loads)
Minimum Footing Width: 12 inches
Minimum Footing Depth: 18 inches below lowest adjacent soil grade
Minimum Reinforcement: Two no. 4 bars at both top and bottom in continuous
footings.

7.6.2 Post-Tensioned Foundations, Units 26-38
Allowable Soil Bearing: 1,500 psf at slab subgrade (allow a one-third
increase for short-term wind or seismic loads)
Ym' differential settlement: 1.5 inch
7.6.3 Lateral Loads: Lateral loads against structures may be resisted by friction
between the bottoms of footings or slabs and the supporting soil. A coefficient of
friction of 0.3 is recommended. Alternatively, -a passive pressure of99jPLftis
recommended for the portion of vertical foundation members embeddd into
Torrey Sandstone. If friction and passive pressure are combined, the passive
pressure value should be reduced by one-third.
7.6.4 Settlement: Settlement resulting from the bearing loads recommended for
shallow foundations on sandstone are not expected to exceed one inch and three-
fourths of an inch, respectively, for total and differential settlements across the
length of.the structure. Deep fill areas underlain by alluvium may experience up
to approximately 1.5 inches of differential settlement.
7.7 Conventional Interior On-Grade Slabs
Slabs should be designed for the anticipated loading. If an elastic design is used, a
modulus of subgrade reaction of 200 kips/ft3 should be suitable. As a minimum, slabs
should be at least 5V2 inches in thickness and be reinforced with at least #3 bars on
1
8
inch centers, each way.
7.7.1 Moisture Protection for Slabs
Concrete slabs resting on soil ultimately cause the moisture content of the
underlying soils to rise. This results fràm continued capillary rise and the ending
of normal evapotranspiration. As concrete is permeable, moisture will eventually
penetrate the slab unless some protection is provided.
To decrease the likelihood of problems related to damp slabs, suitable moisture
protection measures should be used where moisture sensitive floor coverings or
Ceotechtiics Incorporated

Page 11
other factors warrant. A commonly used moisture protection consists of about four
__ • inches of clean sand covered by 'visqueen' plastic sheeting. In addition, two
inches of sand are placed over the plastic to decrease concrete curing problems
associated with placing concrete directly on an impermeable membrane. It has
been our experience that such systems may transmit from approximately 6 to 12
pounds of moisture per 1000 square feet per day. This may be excessive for
some applications
If more protection is needed, we recommend that the slab be underlain by at least
6-inches of minus 3/4-inch crushed rock, with no plastic membrane. In addition,
concrete should have a water to cement ratio no greater than 0.5 and the concrete
should be cured for at least 5 days in accordance with guidelines of the American
Concrete Institute. On-site quality control should be used to confirm the design
conditions.
7.7.2. Exterior Slabs
Exterior improvements such as slabs and sidewalks should be constructed directly
over soils prepared as discussed in Section 7.2. Exterior.slabs should have a
minimum actual thickness of 4 inches, actual thickness, and should be reinforced
with at least 6" X 6", W1.4 X:Wi .4 WWF. Crack control joints should be used on
all exterior slabs, on a maximum spacing. of five feet for sidewalks, and ten feet
each way for slabs.
7.8 Expansive Soils
The soils observed during our investigation consisted of fine to medium grained silty to
clayey sands (SM-SC), which appear to have a low expansion potential, based on Uniform
Building Code criteria. However, representative samples of finish grade materials should
be tested after fine grading is completed in order to verify these observations.
7.9 Reactive Soils
Because of the likelihood that the sulfate content of the on-site soil or groundwater is
sufficient to react adversely with normal cement, we recommend that Type II cement be
used in all concrete which will be in contact with soil.

7.10 Earth Retaining Structures
Cantilever retaining walls backfihled with on-site soil should be designed for an active earth
pressure approximated by an equivalent fluid pressure of 35 thsft3. The active pressure
should be used for walls free to yield at the top at least 0.2 percent of the wall height. For
walls restrained so that such movement is not permitted, an equivalent fluid pressure of
45 lbs/ft3 should be used, based on at-rest soil conditions. The above pressures do not
consider sloping backfill1 surcharge loads, or hydrostatic pressures. If these are
applicable, they will increase the lateral pressures on the wall and we should be contacted
for additional recommendations. Walls should contain an adequate subdrain to eliminate
any hydrostatic forces. Alternative wall drain details are shown in Figures 2 and 3.
Retaining wall backfill should be compacted to at least 90 percent relative compaction,
based onASTM D1557: Backfill should not be placed until walls have achieved adequate
structural strength. Heavy compaction equipment which could cause distress to walls
should not be used.
7.11 Pavement
Currently, materials of the Torrey Sandstone, and granular fill soils derived from the
sandstone and nearby alluvial soils are exposed at existing grades. New grading of the
site will likely changes in soil type at actual street subgade. We are therefore making
preliminary recommendations based on an assumed R-Value of 16 for Street "A" and
Driveways "0" and "E" at the subject site. Our experience with soils in adjacent areas of
the Aviara project indicates that this is a typical worse-case soil condition. Final pavement
design should be based on a sampling and testing program of the actual soil exposed at
street subgrade after grading.
A Traffic Index of 4.5was obtained from Mr. Greg Lundstrom, the project Civil Engineer.
Based on the CALTRANS design method and the minimum requirements of the City of
Carlsbad, we recommend that the section consist of 4 inches of Asphalt Concrete over
4 inches of Aggregate Base. Note that the minimum Carlsbad street section for a Traffic
Index of 4.5 is 4 inches of asphalt over 4 inches of base. This minimum section is
applicable for all soils with an R-Value greater than 16. Consequently, these preliminary
recommendations should remain- applicable unless subsequent sampling of the site soils

Sea Country Homes, Inc. Project No. 0289-001-00 March 29, 1996 (Revised August 19, 1996) Doc. #6-0087
Page 13
indicates that pavement subgrade has an R-Value less than 16. Selective grading is
suggested to assure that this condition does not occur. Asphalt concrete should conform
to Standard Specifications for Public Works Construction, Section 203-6. Type Ill, C2-AR-
4000 asphalt concrete should be used. Aggregate base should conform to Section 26-1
of the CALTRANS Specification for Class II aggregate base or to SSPWC Section 200-2
for crushed miscellaneous base. Aggregate base and the upper 12 inches of subgrade
soil should be compacted to at least 95% of ASTM D1557. Asphalt concrete should be
compacted to at least 95% relative compaction based on the Hveem density.
8.0 LIMITATIONS OF INVESTIGATION
This investigation was performed using the degree of care and skill ordinarily exercised, under
similar circumstances, by reputable geotechnical consultants practicing in this or similar localities.
No other warranty, expressed or implied, is made as to the conclusions and professional opinions
included in this report. The samples taken and used for testing and the observations made are
believed representative of the project site; however, soil and geologic conditions can vary
significantly between borings. As in most projects, conditions revealed by excavation may be at
variance with preliminary findings. If this occurs, the changed conditions must be evaluated by
the geotechnical consultant and additional recommendations made, if warranted.
This report is issued with the understanding that it is the responsibility of the owner, or of his
representative, to ensure that the information and recommendations contained herein are brought
to the attention of the necessary design consultants for the project and incorporated into the
plans, and the necessary steps are taken to see that the contractors carry out such recommenda-
tions in the field.
The findings of this report are valid as of the present date. However, changes in the condition
of a property can occur with the passage of time, whether due to natural processes or the work
of man on this or adjacent properties. In addition, changes in applicable or appropriate standards
of practice may occur from legislation or the broadening of knowledge. Accordingly, the findings
of this report may be invalidated wholly or partially by changes outside our control. Therefore,
this report is subject to review and should not be relied upon after a period of three years:

Gentlemen:
The intent of this addendum is to provide additional recommendations regarding retaining walls
at the subject site. The recommendations provided in Section 7.10 of the referenced report
remain applicable. However, ills our understanding that 2:1 (honzontal;vertical) sloping backfluis
are proposed for retaining walls at the site. Walls with a 2:1 sloping backfill should be designed
for an active pressure approximated by a fluid with an equivalent unit weight of 63 pd. This
active pressure is applicable only to walls free to yield at the top by at least 0.2 percent of the
wall height.
In order to develop larger resisting moments, retaining wall footings may be deepened. The
recommendations for shallow foundations given in Section 7.6.1 of the referenced report remain
applicable to retaining wall footings, with the following modifications. For each additional 1 foot
of total embedment below the minimum recommended depth of 2 feet, the allowable bearing
capacity may be increased by 500 psf, up to a maximum of 4000 paf. In other words, footings
with depths of 2, 3, 4, and 5 feet have allowable bearing capacities of 2500, 3000, 3500, and
4000 psf, respectively. -
