Dear Mr.. Elliott:
V. V
This report is to present the results of our soil tests and
observations done at your re'que'st for the grading of Elm Avenue of
the above referenbed project.
The recommendation for grading preparation contained in our.
Preliminary Soil Investigation Report dated 23 August 1976 were
followed to our satisfaction. . . .
V.
All ut (native ground) portions of Elm Avenue were. undercut
2 feet .and then refilled and compacted at least 90% of the maximum
dry density. .
V V The results of our observations, field.density and laboratory
tests indicate the compacted fill and recompactedground has been
placed at not less, than 90% of the maximum dry density.
The approximate undercut and the fill areas tested are shown
on the enclosed plot plan
; Both laboratory compaction and field density test procedures
and results are presented on the following pages
We understand that all grading for the referenced project has
been completed. However, if additional.fill or backfill is to be
placed we should be notified to insure that proper compaction is
achieved
Respectfully submitted,

DENSITY DATA :
1 - Laboratory Compaction
Laboratory compaction tests were performed as specified
by ASTM D1557-64T (method A). This test method uses the minus
#4 sieve soil in a 4 inch diameter, 4 inch high cylindrical mold.
The sample is formed with a 10 pound hammer falling 18 inches
for 25 blows on each of 5 layers

Field density tests were taken at selected locations during
the grading to determine the moisture and density conditions of
the filled area These tests were performed according to ASTM
01556-64, the sand cone method
