1, Avoid the use of isolated intoiior piers. Use continuous interconnected
reinforced footings throughout, and place these at a minimum depth of
24 inches below the lowest adjacent exterior final ground surface. Where
in-place rock conditions exist at shallov/er depths, then less depth of ox-
covation is permissible to o minimum of 12 inches -
2, Reinforce and interconnect continuously willi itt*el bars all intciioi arid
exterior footings with one ff5 Lai at 3 inches above the bottom of the
footings and one "5 bar placed 1 1/2 inchc i below the top of Ihc stc-n s
of the footings.
3, Raised wooden floors that span between continuous foolinys oic- l>c-it, or
use concrete slabs icinforced with at least 6x6-10/10 welded wiio fabric.
A minimum of 4 inches of ciubhtJ iock 3/4 to 1 Inch in sue should bo

PRELIMINARY GEOTECHNICAL INVESTIGATION
FOR THE PROPOSED SINGLE-FAMILY RESIDENCE
ON CAZADERO STREET
IN CARLSBAD, CALIFORNIA
INTRODUCTION
This report presents our opinions resulting from our
Geotechnical Investigation on the subject property. Our
investigation was performed on January 21, 1983. The
purpose of this investigation was to evaluate the site from
a geologic and soils standpoint, and to provide preliminary
recommendations for your use in overall site development.
LAYOUT OF REPORT
The body of the report contains the text of our findings
and recommendations. Details of our field and laboratory
work are presented in the Appendices at the end of the
report. Key statements in the text are underlined.
SCOPE OF SERVICES
The scope of services performed in the course of this
investigation included:
1. Review of published and unpublished reports and
maps pertaining to the subject site and its
vicinity;
2. Geologic mapping of the site;
3. Subsurface exploration consisting of three
test pits;
4. Laboratory testing of representative soil samples
obtained during the field investigation; and,
5. Analysis of field data and preparation of this
report, including our findings, conclusions and
recommendations.

PROPOSED DEVELOPMENT
It is our understanding that the proposed development of
the rectangular shaped site consists of the construction of
a three-story, framed, 3,447 square foot single-family
residence, including a 2 car garage, 5 bedrooms and 3
fireplaces. There will be both a slab-on-grade and a raised
wooden floor.
SITE DESCRIPTION
Legal description of the site is:
Lot 746 of La Costa Meadows, Unit No. 4 in the
County of San Diego, Map No. 7367.
Parcel No. is 215-400-05. Lot size is 25,106 square feet
(0.576 acres).
The subject site is situated on the northwest side of
Cazadero Street in Carlsbad, California.
The site affords 147.00 feet of frontage along Cazadero
Street. The depth of the property is approximately 171
feet. Please reference attached Location Map, Plate No. 1,
and the Site Plan, Plate No. 2. Site Photographs are
shown on Plate No. 3.
The highest portion of the site occurs at the southeast
corner with an existing elevation of about 465 MSL. The
lowest portion of the site occurs at the northwest corner
with an elevation of about 425 MSL. The difference in
elevation is therefore about 40 feet. This occurs in a
horizontal distance of about 226 feet, thus giving the
property an average slope gradient of 17.7 percent.
Vegetation consists of sparse low grasses and native
medium shrubs and bushes. Large rocks to 2% feet in
-2-
SITE DESCRIPTION (Continued)
diameter occur on the surface along with numerous smaller
rocks.
Soil material consists mainly of bedrock overlain by
six to eighteen inches of silty to clayey gravelly soil,
ranging from non-expansive to highly expansive.
No surficial water seeps were observed on the pioperty.
And no water tables were encountered in any of the test
pits.

GEOLOGY
The subject site is located in Carlsbad, California.
The property is underlain by Jurassic and/or Tnassic
Metavolcanic Rocks.
FIELD AND LABORATORY INVESTIGATION
The subsurface investigation consisted of three test pits»
trenched with a backhoe to a maximum depth of five feet.
The location of test pits are shown on the Site Plan. The
test pits were carefully logged and sampled by this firm.
Representative samples of the various soils encountered in
the test pits were returned to the laboratory for evaluation
and appropriate testing. Logs of the test pits and labor-
atory test results are presented in Appendices A and B
of this report, respectively.

CONCLUSIONS AND RECOMMENDATIONS
A. General
The site is suitable for the proposed development from
a geologic and soils engineering standpoint, within the
framework of our recommendations. There are, however,
certain constraints which must be taken into account. The
constraints, conclusions and recommendations follow.
B. Slope Stability
We recommend that any required permanent cut or fill
slopes be constructed to an inclination no steeper than 2.Q
horizontal to 1.0 vertical. Placement of fill near the tops
of slopes should be carried out in such a manner so as to
assure that loose, uncompacted soils are not sloughed over
the tops and allowed to accumulate on the slope face.
C. Grading and Earthwork
1. Rippability
Some difficulty may be encountered when excavating
footings with conventional earth-moving equipment. Heavy
dozers with a single ripper tooth may have to be utilized
when excavating in fractured bedrock material.
2. Recommended Grading Specifications
Grading should be performed in accordance with
Appendix C, "Recommended Grading Specifications."
D. Foundation and Slab Recommendations
1. Recommendations for Expansive Soils
Field observations and laboratory testing indicate
that the expansion potential of the finished pad soils will
be in the highly expansive range. We recommend that these
expansive soils be capped with a minimum thickness of three
feet of non-expansive soil material and/or incorporated
into deeper fill areas. In lieu of a three-foot cap of
non-expansive soils, footings and slabs-on-grade may be
founded on expansive soils. Recommendations for foundations
and slab design, considering the expansive soil conditions
and a two/three-story structure, are as follows:
a. All exterior footings, including the garage
door beam, should be 24 inches deep below slab subgrade,
continuous, and contain two No. 5 bars top and bwo No. 5
bars bottom. Interior footings may be 18 and 24 inches
deep for two and three-story portions, respectfully.
b. Living area floor slabs should be a minimum of
four inches thick with 6x6-W2.9/W2.9 welded wire fabric
at mid-height over 1 inch of sand over 6 mil visqueen
moisture barrier over 4 inches of gravel or sand base.
c. Garage floor slabs should be 4 inches thick
with 6x6-W2.0/W2.9 welded wire fabric, isolated from stem
wall footings, over 4 inches of gravel or sand base. No
moisture barrier is required.
d. Pre-soak under all slabs to a depth of 24
inches to 5 percent above optimum moisture content. If
a raised floor is used or the pad is capped with three
feet of non-expansive soil material, exterior footings may
then be founded a minimum depth of 18 and 24 inches below
lowest adjacent subgrade for two and three-story portions,
respectfully.
-9-
2. Soil Bearing Pressure
Structures may be supported on conventional shallow
footings bearing in bedrock, firm natural ground, or
compacted fill. At the minimum depths specified, footings
may be designed for an allowable dead plus live load
bearing pressure of 2,500 and 3000 pounds per square
foot (psf) for two and three-story portions, respectfully.
This value shall be verified upon completion of the earth-
work operations. This value may be increased by one-third
for short-term loads, including wind or seismic. Footings
should have a minimum width of 15 and 18 inches for two
and three-story portions, respectfully.
Footings located adjacent to the tops of slopes should be
extended sufficiently deep so as to provide at least 5
feet of horizontal cover between the footing and the
slope at the footing bearing level.
Settlements under building loads are expected to be within
tolerable limits for the proposed structures. We estimate
post-construction differential settlements across any one
building will not exceed 1/2 inch.
3. Lateral Loads
Lateral load resistance for the buildings and
retaining walls supported on footing foundations may be
developed in friction between the foundation bcttoms and
the supporting subgrade. An allowable fnational resistance
of 200 psf is considered applicable. An additional allow-
able passive uniform pressure of 125 pounds per square foot
acting against the foundations may be used in design provided
the footings are poured neat against the adjacent compacted
fill materials or undisturbed natural soils.
When combining passive pressure and fnational resistance,
the passive pressure component should be reduced by one-
third. For design of isolated poles, such as flagpoles,
the allowable passive earth pressure may be increased by
100 percent.
-10-
E. Pavements -
On-site soils range from poor to good subgrades.
R-value testing and pavement design should be performed
after rough subgrade for driveways and parking areas is
achieved.
Tentative pavement design considerations are presented below:
2 VAC over 7" AB over 12" SG
Notes: (a) AC is type B asphaltic concrete meeting re-
quirements of Section 39 of State of California Standard
Specifications, 1978.
(b) AB is Class 2 aggregate base in accordance with
Section 26 of State of California Standard Specifications,
1978. AB shall be compacted to 95 percent relative compaction
(c) SG is imported non-expansive soil material
compacted to 95 percent relative density.
(d) Prior to placing the aggregate base, the sub-
grade soils should be rolled with smooth-wheeled compactor
to produce a firm, smooth, non-yielding surface.
If you should require any clarification of the above,
please do not hesitate to contact this office.
Very truly yours,

LIMITATIONS
Conclusions and recommendations made in this report are
based on the assumption that the soil and geologic
conditions do not deviate appreciable from those disclosed
by the test pits. If variations are encountered during
construction, TORREY PINES CONSULTING should be notified
so we may make supplemental recommendations, if this
should be required.
Evaluation of soil materials for support of structures
includes continuous inspection during grading. The soil
engineer should continue his services through inspection
of grading, including construction of fills, foundation
excavations, trench backfill, backfill behind retaining
walls, and installation of necessary drainage systems.

APPENDIX C
RECOMMENDED GRADING SPECIFICATIONS
GENERAL
It shall be the Contractor's responsibility to place,
spread, water and compact the fill in strict accordance
with these specifications. A Soils Engineer shall be the
Owner's representative to inspect the construction of fills.
Excavation and the placing of fill shall be under the direct
inspection of the Soils Engineer, and he shall give written
notice of conforraance with the specifications upon com-
pletion of grading. Deviations from these specifications
will be permitted only upon written authori2ation from the
Soils Engineer. No deviation from these specifications will
be allowed, except where specifically superceded in the
Preliminary Geotechnical Investigation Report, or in other
written communication signed by the Soils Engineer.
II. SCOPE
The placement of fill by the Contractor shall include all
clearing and grubbing, removal of existing unsatisfactory
material, preparation of the areas to be filled, spread-
ing and compaction of fill in the areas to be filled, and
all other work necessary to complete the grading of the
filled areas.
III. MATERIALS
A) Materials for compacted fill shall consist of any
material that, in the opinion of the Soils Engineer, is
suitable for use in constructing fills. No material of
a perishable, spongy, or unsuitable nature shall be used
in filling.
-21-
B) Material placed within 24 inches of rough lot grade
shall be select material that swells less than 3% when
compacted as hereinafter specified for compacted fill and
when subjected to an axial pressure of 144 psf, unless
expansive soil recommendations are given in this report.
C) During grading operations, soil types other than
those analyzed in the report of the soil investigation
may be encountered by the Contractor. The Soil Engineer
shall be consulted to determine the suitability of these
soils.
IV. COMPACTED FILLS
A) GENERAL
1. Unless otherwise specified, fill material shall be
compacted by the Contractor while at a moisture content
near the optimum moisture content and to a density that
is not less than 90% of the maximum density determined in
accordance with ASTM Test No. D-1557-70.
2. Potentially expansive soils may be used in fills
below a depth of 24 inches and shall be compacted at
a moisture content greater than the optimum moisture
content for the material, unless recommendations for
expansive soils are given in this report.
B) CLEARING AND PREPARING AREAS TO BE FILLED
1. All objectionable material shall be disposed of by
the Contractor.
2. All objectionable material shall be removed by the
Contractor from the surface upon which the cill is to be
placed, and any loose and porous soils shalL be removed
to the depth specified. The surface shall then be
scarified to a minimum depth of 6 inches and recompacted.
3. Prior to grading, the site should be cleared of
surface obstructions and stripped of brush and vege-
tation . Obstructions which extend below finish grade
should be removed and replaced with compacted fill.
-22-
Vegetation and debris from the clearing operation should
be removed from the site.
4. All existing on-site soil and bedrock materials are
generally suitable for reuse as fill. Fill materials
should not, in general, contain rocks or cobbles greater
than 6 inches in largest dimension. However, larger rock
fragments may be incorporated into the lower portion of
fills, provided the method of spacing and compaction are
approved by the Soils Engineer.
5. Where fills are constructed on slobes steeper than
5 horizontal to 1 vertical, the slope of the original
ground on which the fill is to be placed shall be bench-
ed and keyed by the Contractor as directed by the Soils
Engineer. The benches and keys shall extend completely
through the soil mantle and into the underlying formational
materials.
6. Compaction of slopes should be achieved by over-
building the slopes laterally, then cutting back to the
design line and grade, or by back-rolling with sheeps-
foot at frequent intervals as the fill is placed, followed
by final rolling of the entire slope. Feathering of fill
over the tops of slopes should not be permitted. All
fills should be placed and grading performed in accord-
ance with applicable local grading ordinances and this
report.
7. After the foundation for the fill has been cleared
and scarified, it shall be compacted as specified for fill.
C) PLACING, SPREADING, AND COMPACTION OF FILL MATERIAL
1. The fill material shall be placed by the Contractor
in layers that, when compacted, shall not exceed 6 inches.
Each layer shall be spread evenly and shall be thoroughly
mixed during the spreading to obtain uniformity of material
in each layer.
2. When the moisture content of the fill material is
above that specified by the Soils Engineer, the fill
-23-
material shall be aerated by the Contractor by blading,
mixing or other satisfactory methods until the moisture
content is as specified.
3. When the moisture content of the fill material is
below that specified by the Soils Engineer, water shall
be added by the Contractor until the moisture content is
as specified.
4. After each layer has been placed, mixed and spread
evenly, it shall be thoroughly compacted by the Contractor
to the specified density. Compaction shall be accomplished
by suitable compacting equipment.
5. Utility trenches should be backfilled with compacted
fill. Backfill material should be placed in lift thick-
nesses appropriate to the type of compaction equipment
utilized and compacted to 90 percent by mechanical means.
6. If a daylight pad should occur where the building
will partially be underlain by compacted fill and partly
by bedrock and/or natural soil, the cut portion of the lot
should be overexcavated to a depth of at leat 2^ feet
below pad subgrade and replaced with compacted fill.
This overexcavation should be extended a minimum of 5
feet beyond the edge of the perimeter footings.
V. GRADING CONTROL
A) Observations and compaction tests shall be made by
the Soils Engineer during grading so that he can state that
the fill was constructed in accordance with the
specifications.
B) The Soils Engineer shall make field density tests
in accordance with ASTM Test No. D-1556-64. When these
tests indicate that the density is below the specified
density, that portion shall be reworked until the
specified density has been obtained.
-24-
VI. CONSTRUCTION OBSERVATIONS
A) During construction, the Contractor shall properly
grade all excavated surfaces to provide positive drainage
and prevent ponding of water. He shall control surface
water to avoid damage to adjoining properties or to finish-
ed work on the site. The Contractor shall take remedial
measures to prevent erosion of freshly graded areas and
until such time as permanent drainage and erosion control
measures have been installed.
B) After completion of grading and the Soils Engineer
has finished his observations of the work, no further
excavation or filling shall be done except under the
observation of the Soils Engineer.

The application must be signed by the owner (or his authorized representative) of
the property to be served. The total charges must be paid to the District at the
time the application is submitted.
If a service lateral is required, it will be installed by the Leucadia County Water
District. The service lateral is that part of the sewer system that extends from
the main collection line in the street (or easement) to the point in the street (at
or near the applicant's property line) where the service lateral is connected to
the applicant's building sewer. The applicant is responsible for the construction,
at the applicant's expense, of the sewer pipeline (building sewer) from the appli-
cant's plumbing to the point in the street (or easement) where a connection is made
to the service lateral.
The connection of the applicant's building sewer to the service lateral shall be
made by the applicant ai his expense. The connection must be iriade in conformity
with the District's specifications, rules and regulations; and IT MUST BE INSPECTED
AND APPROVED BY THE DISTRICT BEFORE THE SEWER SYSTEM MAY BE USED BY THE APPLICANT.
THE APPLICANT, OR HIS AUTHORIZED REPRESENTATIVE, MUST NOTIFY THE DISTRICT AT THE
TIME INSPECTION IS DESIRED. ANY CONNECTION MADE TO THE SERVICE LATERAL OR COLLEC^
TION LINE WITHOUT PRIOR APPROVAL AND INSPECTION BY THE DISTRICT WILL BE CONSIDERED
INVALID AND WILL NOT BE ACKNOWLEDGED.
The prorated sewer service fee is based upon the date the District estimates that .
service will begin and covers the balance of the fiscal year. There will be no
additional fee or refund if service actually commences on a different date. For
succeeding fiscal years, the sewer service fee will be collected on the tax roll
in the same manner as property taxes.
The undersigned hereby agrees that the above information given is correct and agrees
