CITY OF CARLSBAD Building Department
In accordance with the request of Mr. Jerry L. Rombotis of your
firm, we have provided soil engineering services in conjunction
with the grading of the subject site. These services included
observation of the removal of potentially expansive soil exist-
ing within two feet of rough lot grade and the testing of fill as
placed and compacted. In addition, settlement plates were
installed in order to evaluate the consolidation of the underlying
natural soils.
Site preparation, compaction and testing were done between Feb-
ruary 6 and April 27, 1967, in accordance with the Earthwork
Specifications and Recommendations presented in our letter dated
January 10, 1967. Fill was placed, compacted and tested on Lots
1 through 35.
As the site grading progressed, the compaction procedures were
observed and compaction tests were made to determine the relative
compaction of the fill in place. Field observations and compaction
test results indicate.that the fill has been compacted to 90 percent
or more of maximum laboratory density, The results of compaction
tests are given on the attached forms.
Laboratory tests to determine moisture-density relationships,
maximum dry density, optimum moisture content, grain size distri-
bution, plasticity characteristics and strength characteristics
were performed on representative samples of the material used for
fill. The results of laboratory tests are given on the attached
forms.
Laboratory tests indicate that nonexpansive fill was placed within
2 feet of rough grade on all fill lots noted above,
A visual inspection of the subject site at the completion of grading
indicates that potentially expansive soil is not evident at finish
grade on either cut or fill lots.

In accordance with the recommendation made in the report entitled,
"Addendum to Foundation Soil Investigation", by Dresselhause
Engineers, Consulting Engineers, dated January 6. 1966, four settle-
ment monuments were nlaced in the fill at the locations noted below:
Boundary Line between Lots 19 and 20
Boundary Line between Lots 23 and 24
Boundary Line between Lots 30 and 31
At the Nly Return Lot 1
Elevation readings were made by Raymond R. Ribal, Civil and
Sanitary Engineer, and the results were reported in his letter
dated May 3, 1967. The results given in this letter indicate
that no discernable settlement nas occurred during the period
between April 19 and May 3, 1967.
Footings for residential structures placed on nonexpansive un-
disturbed soil or nonexpansive properly compacted fill may be
designed for a bearing pressure of 2,000 pounds per square foot,
(total load) at a depth of 12 inches below rough lot grade.
The elevation of compaction tests shown as finished grade (F.G.)
tests correspond to the elevations shown on the grading plans for
Laguna Riviera Tract, Unit No. 1, City of Carlsbad, California,
dated January 7, 1967, prepared by Raymond R. Ribal, Civil Engineer.
This final report covers the fill placed under our observation
during the dates specified above. 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
of 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.
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 the slope should be
extended until the bottom edge of the footing is 5 feet horizontally
from the outside face of the slope.
The inspections and tests of compaction made during the period of
our services on the subject site were in accordance with the local

acceptable standards for this pet-Sod. 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.
