FINAL REPORT OF ENGINEERING
ON TESTING
LOTS 1 THROUGH 33
APR 2 6 1973
CITY OF CARLSBAD Building Department
mw-I
CARLSBAD, CALIFORNIA
In accordance with your request, and our agreement dated October 2, 1972, 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 tree stumps and tree root systems where
encountered prior to placing fill.
(3) Observation of the removal of alluvial soil and existing loose fill where encountered.
(4) Taking field density tests in the fill placed and compacted.
(5) Performing laboratory tests on representative samples of the material
used for fill.
Site preparation, compaction, and testing were done between September 22, 1972,
and April 13, 1973, in accordance with the "Specifications for Controlled
Fill" in our report entitled "Review of Existing Soil Investigation Report - Additional Recommendations and Earthwork Specifications, Buena Woods Unit No. 1,
Carlsbad, California," dated September 13, 1972.
Fill was placed, compacted, and tested on Lots 1 through 15 and 20 through 30.
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 in-
dicate 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 strength and sweli.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 and a visual inspection indicate that nonexpansive fill
was placed within 2 feet of rough grade on all fill lots noted herein.
A visual inspection of cut Lots 16 through 19 and 31 through 33 at completion
of grading indicates that potentially expansive soil is not evident at rough
grade surface.
Foundations for single or two-story residential structures placed on non-
expansive 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. 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.
Structures that will not tolerate differential settlements (such as foun- dations, 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.
The elevations of compaction tests , shown as'finished grade (FG) tests,
correspond to the elevations shown on the grading plans for "Buena Woods,"
dated June 28, 1972, prepared by Roy 1. Klema, Engineers, Inc., Escondido, 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 specifi-
cations 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 recom-
mendation.
-
-
The inspections and tests of compaction made during the period of our serv-
ices on the subject site were in accordance with the local acceptable stand-
ards 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.
