On June 27 and 30, 1987, a representative of our firm performed density
tests in the fill for the house pad on the above referenced project. Tests
were performed at random locations, in accordance with ASTM D 2922-81
and ASTM D 3017-78 Nuclear Density Test Procedure. Tests were performed
as per authorization of R.L. Harmon, M.D.
The estimated locations of the tests are presented on the attached plan
with their results being summarized on the attached test report sheet. A
total of three (3) density tests were performed. Tests results indicate that
after reworking areas of low density, a minimum of ninety. (90)' percent*
relative compaction has been obtained within the areas tested. The
maximum density -optimum moisture were determined in the laboratory in
accordance with ASTM D 1557-78, Method A or C. Test results are as
follows:

1. The project is located on the west side of Avenida Rubio, one 0) lot
north of Calle Chillon in the City of La Quinta, California.
2. Prior to our arrival at the site, the fill had been placed.
3. First testing indicated low density.
4. On June 30, 1987, the failure was retested.
5. The purpose of testing was to observe compliance with the minimum
requirements of the City of La Quinta, California.
Limitations
This firm did not perform a soils investigation, did not conduct any tests to
determine the general condition, adequacy or stability of soils on the
property, nor did it observe the backfilling or compacting operations which
were already completed at the time our personnel were called to the site.
The only services performed were the specific moisture and density tests
summarized in this report. These test results provide only limited
information about the surface materials observed at the locations and
depths tested and cannot be relied upon for information about subsurface
conditions or compaction, or to determine the appropriateness of any design
or construction of improvements on the site. No inspection was made of the
contractor's work and no guarantee or warranty of that work in backfilling
or compaction of the soils on the site is made or implied.
If there are any questions, please do not hesitate to contact this office.
Respectfully submitted,
BUENA ENGINEERS., NC.
