FINAL REPORT OF ENGINEERING
OBSERVATION AND COMPACTION TESTING
LAGUNA RIVIERA
LOTS 174 THROUGH 195 - UNIT NO. 6
LOTS 196 THROUGH 223 - UNIT NO. 7
CARLSBAD, CALIFORNIA
In accordance with your request, and our agreement dated September 22,
1975, we have provided soil engineering services in conjunction with the
grading of the subject site. These services included:
(1)
(2)
(3)
(4)
(5)
Engineering observation of the grading operation.
Observation of the removal or scarification and recompaction of
loose surface soil and loose fill soils, where encountered, prior
to placing compacted fill.
Observation of the removal of potentially highly expansive soil
from the top 2 feet of rough lot grade and replacing it with
nonexpansive or low to moderately expansive soil.
Taking field density tests in the fill placed and compacted.
Performing laboratory tests on representative samples of the
material used for fill.
Current site preparation, compaction, and testing were done between
September 24 and October 27, 1975 in accordance with the "Specifications
for Controlled Fill" in our report entitled "Updated Soil Investigation
Report, Laguna Riviera No. 6 and 7, Carlsbad,. California", dated June
20, 1975 and revised on June 23, 1975.

Prior fill placed under controlled conditions was compacted and tested
on this site in 1974. The results of compaction tests are included in
this report. During this initial grading period, fill was placed in a
canyon area in Unit 7. Some excavation was done on both Unit 6 and 7.
Fill was placed, compacted, and tested during the current grading period
on Lots 174 through 185 and 187 through 195 in Unit No. 6 and on Lots
196 through 206, 208, 209 and 213 through 223 on Unit No. 7.
As the site grading progressed, the 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
characteristics, and swell characteristics were performed on representative
samples of the material used for fill. The results of laboratory tests
are given on the attached forms.
During the grading operation certain lots were specially treated to
provide a specified depth of selected soil at finish grade. This special
treatment consisted of the placement of special finish grade soil and
undercutting of highly expansive clay from finish grade and replacing it
with soil of less expansive nature. The lots were then classified in
regard to whether the soil at finish grade is nonexpansive or low IIO
moderately expansive in nature. In general, finish grade soil refers to
the upper approximate 2 feet of soil on the lot as defined by rough or
compacted lot grade.
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.
Summary of Finish Grade Soil Conditions
(1) Cut, fill or cut-fill lots having nonexpansive soils at finish
grade are,Lots 177 through 184, 186, 196, 197, 198, 204, 205, 206,
208, 210, 211, 212, 214, 215 and 219.
(2) Cut, fill or cut-fill lots having low to moderately expansive
finish grade soils are Lots 174, 175, 176, 185, 187 through 195,199
through 203, 207, 209, 213, 216, 217, 218, and 220 through 223.

(3) On those lots where potentially expansive soil is evident or where
it is encountered in footing excavations, special foundation design
should be observed. Special foundations for single or two-story
residential structures on lots that contain such potentially expansive
soil, should be designed in accordance with the recommendations in
Paragraph (2) below.
Foundation Recommendations
(1) Foundations for single or two-story residential structures placed
on nonexpansive undisturbed soil or nonexpansive properly compacted
fill may be designed for a bearing pressure,of 2,000 psf at a depth
of 12 inches below compacted fill or undisturbed cut lot grade.
(2) Foundations for single or two-story residential structures on lots
tha.t contain low to moderately expansive soil should be designed
for an allowable soil bearing pressure of 2,000 psf and should
include the following reinforcing.
Rough or Compacted
Grade
.
t
X4 Bars, top and bottm
The above design recommendations are not intended to eliminate
heave, but are intended to minimize its effects. Footings placed
on expansive soils should be expected to experience local heaving.
(3) The bearing pressures given above are for total dead plus live load
and may be increased for loads that include wind or seismic forces.
All footings should have a minimum width of 12 inches.
(4) The exposed soils within footing excavations and under slabs should
not be allowed to dry out before construction. Soils should be
wetted as required prior to placment of concrete.
(5) 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.
(6) All slopes should be properly drained, Planted and maintained in
order to help control erosion.

The elevations of compaction tests shown as finished grade (FG) tests
correspond to the elevations shown on the grading plans for "Carlsbad
Tract 74-19", dated September lB, 1975, prepared by Raymond R. Ribal,
Brea, 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 recommendation.
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 will 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.
