Attention: Mr. Leonard Minor
INTERIM REPORT OF ENGINEERING OBSERVATION AND COMPACTION TESTING CARLSBAD PALISADES UNIT NO. 1
OFFSITE FILLS (FUTURE UNIT ~0. 2)
CARLSBAD, CALIFORNIA
In accordance with your request and our proposal dated July 29, 1974, we have
provided soil engineering services in conjunction with the placing of offsite
fills at the subject site. These services included:
(1) Engineering observation of the grading operation.
(2) Taking field density tests in the fill placed and compacted.
(3) Performing laboratory tests on representative samples of the material
used for fill.
Site preparation, compaction and testing were done between November 21, 1974
and February 25, 1975 in accordance with the "Specifications for Controlled
Fill" in our report entitled "Soil Investigation for the Proposed Agua Hedionda
63 Acre Site, Carlsbad, California", dated March 3, 1973.
Fill was placed, compacted and tested in the following areas during the grading
of Carlsbad Palisades Unit No. 1:
(1) A cut slope located south and adjacent to Tamarack Avenue in future Unit
No. 2 was excavated and rebuilt with compacted fill to buttress the slope in accordance with Section 8-B of the approved plans. Minor ad- ditional fill was placed above the buttress to accomodate a water line. This latter fill was placed in an area designated as an extension of Neblina Drive and a future street.

(2) .Fill was placed, compacted and tested east of the temporary access road and north of Building Pads 115 through 119 and Pad 106.
(3) Fill was placed, compacted and tested in an.area southwest of Palisades
M;;; approximately 300 feet north of its lntersectlon*wlth Tamarack . This was a daylight fill placed to provide drainage.
Compaction procedures were observed, and field density tests were made to determine the relative compaction of the fill in place. Field observations and field density test results indicate that the fill has been compacted to 90% or more of maximum laboratory density. The approximate locations of
field density tests and the limits of compacted fill have been recorded on a
copy of the grading plan for reference. The results of field density tests
and of relative compaction, expressed as a percent of maximum laboratory density, are given on the attached forms.
Laboratory tests to determine moisture-density relationships, maximum dry density, optimum moisture content, grain size distribution, plasticity char-
acteristics, and strength and swell characteristics were performed on repre- sentative samples of the material used for fill. The results of laboratory tests are given on the attached forms.
It is our understanding that additional grading will be done in these areas at
a later date. Foundation recommendations will be made in our final report at
the 'completion of grading.
The elevations of compaction tests shown as finished grade (FG) tests corres- pond to the elevations shown on the grading plans for "Carlsbad Tract 73-8 (Carlsbad Palisades Unit No. l)", Sheet 6 of 6 in prints dated September 19, 1974, prepared by Rick Engineering Company, San Diego, California. Elevations
;;;eizcations shown in this report are based on field surveys established by
.
This report covers the fill placed under our observation during the dates specified herein. Additional fill placed after these dates should be compacted under the observation of this office and tested to assure compliance with the earthwork specifications for the project. This office should be contacted at
least 24 hours prior to start of grading operations.
'The inspections of foundation preparation, types of materials and soil place-
ment and compaction as well as tests of compaction made during the period of
our services on the subject site were in accordance with the local acceptable standards for this period. The conclusions or opinions drawn from the tests and site inspections apply only to our work with respect to grading and repre-
sent conditions at the date of our final inspection.

CARLSBAD, CALIFORNIA
In accordance with your request and our proposal dated July 29, 1974,
we have provided soil engineering services in conjunction with the grading
of ~the subject site. These services included:
(1) Engineering observation of the grading operation.
(2) Observation of the removal of loose surface and alluvial soil prior
to placing fill.
(3) Observation of the removal of potentially highly expansive soil from
the finish grade pad areas and replacing it with nonexpansive soil.
(4) Performing period~ic geological inspections of the cut slope areas.
(5) Observation of the special preparation of foundation areas of fill
slopes over 50 feet in height.
(6) Observation of the construction of buttress fills in cut slopes where required.
(7) Taking field density tests in the fill plated and compacted.

preparation, compaction and testing were done between October 25, 1974 and February 25, 1975 in accordance with the "Specifications for Controlled
Fill" in the Woodward-Gizienski & Associates report entitled "Soil Investigation
for the Proposed Ranch0 Agua Hedionda-63 Acre Site, Carlsbad, California,"
dated March 3, 1973, and addendum reports dated May 16, 1973 and October 1,
1973 (revised October 26, 1973) and letter of August 22, 1974.
GENERAL GRADING AND COMPACTION CONTROL PROCEDURES
Fill was placed, compacted and tested on all the subject pads covered in this
report, that is Pads 32 through 120. Preliminary site preparation included removing, loose or porous surface soils, where encountered, and special preparation
of the foundation for the fill slope at the rear of Pads 67 through 77 and
99 through 106 which was done in accordance with our recommendations and is
similar to Section "A-A" of the approved grading plans. In addition, the
toes of two slopes, the large cut at the southwest corner of the site, and the toe of the cut-fill slope at the rear of Pads 38 through 45, were excavated and buttressed with compacted fill in accordance with recommendations and'
Section "B-B" of the grading plans.
AS the site grading progressed, the compaction procedures were observed, and field density tests were mdae to determine the relative compaction of the fill in place. Field observations and field density test results indicate that the fill has been compacted to 90% or more of maximum laboratory density.
The approximate locations of field density tests and the limits of compacted
fill have been recorded on a copy of the grading plan for reference. The
results of field density tests and of relative compaction, expressed as a
percent of maximum laboratory density, are given on the attached forms.
Laboratory tests to determine moisture-density relationships, maximum dry
density, optimum moisture content, grain size distribution, plasticity character- istics, and strength and swell characteristics were performed on representative samples of the material used for fill.
given on the attached forms.
The results of laboratory tests are
musti GRADE PREPARATION
During the grading operation certain pads were specially treated to provide a specified depth of selected soil at rough grade.
Laboratory tests and visual inspection indicate that nonexpansive fill was placed within 3 feet of rough grade on all building pad areas noted herein, and within 2 feet of rough grade in other areas including the remainder of
the level portions of the lots, and common and parking areas.

The cut portions of Pads 1, 21, 22, 30, 31~and 33 to 61 were undercut to remove
potentially expansive soil. The.expansive soil was replaced with nonexpansive
fill to a depth of 3 feet below rough pad grade within the proposed building pad area. Other level lots were undercut and replaced to a depth of ~' 2 feet.
Rough lot grade is defined as that grade set in the field by the grade checker
from reference stakes established by the surveyor and represents rough grade
at the time we were inspecting the removal and replacement of expansive soils.
Likewise the depths of undercutting of expansive soil and/or depths of placement of nonexpansive soil were in accordance with measurements made by and grades
set by the contractor's grade checker.
FOUNDATION RECOMMENDATIONS (ALL LOTS)
(1) Foundations for single or two-story multi-dwelling structures placed on nonexpansive properly compacted fill may be designed for a bearing pressure :
of 2,500 psf (dead plus live loads) at a depth of 12 inches below compacted
fill lot grade. Footings should have a minimum width of 12 inches. These
pressures may be increased by one-third for loads that include wind or seismic
forces.
(2) Structures that will not tolerate differential settlements (such as foundations, swimming pools, concrete decks, walls, etc.) should not be located within 5 feet of the top of a slope. Footings located closer than 5 feet from the
top of a slope should be extended in depth until the outer bottom edge of the footing is 5 feet horizontally from the outside face of the slope.
(3) It should be anticipated that structures, such as swimming pools, that
extend below a de&h of 2 feet may be founded in potentially expansive soils
and may require special treatment or design.
LIMITATIONS
The elevations of compaction tests shown as finished grade (FG) tests correspond
to the elevations shown on the grading plans for "Carlsbad Tract 73-8, Carlsbad Palisades Unit No. 1", print dated September 19, 1974, prepared by Rick Engineering Company, San Diego, California. Elevations and locations shown in this report are based on field surveys established by others.
This report covers the fill placed under our observation during the dates specified
herein. Additional fill placed after these dates, as well as the backfill
in utility trenches located within 5 feet of a building and greater than 12 inches deep, or any trench 5 feet or more from a building and in excess of 5 feet in depth, should be compacted under the observation of this office and
tested to assure compliance with the earthwork specifications for the project.
This office should be contacted at least 24 hours prior to backfilling operations. Utility service trenches within 5 feet of a building that are perpendicular
to the building footings and are less than 12 inches wide and less than 3 feet deep are not subject to this recomnendation.

The inspections of foundation preparation, types of materials and soil placement
and compaction as well as tests of compaction made during the period of our
services on the subject site were in accordance with the local acceptable standards
for this period. The conclusions or opinions drawn from the tests and site
inspections apply only to our work with respect to grading and represent conditions
at the date of our final inspection.
We accept no responsibility for any subsequent changes made to the site by others or by uncontrolled action of water or by failure of others to properly
repair damages caused by uncontrolled action of water.
