The following testing was performed during post grading operations:
. Waterline Trench Backfill . Dry Utility Trench Backfill
. Sidewalk Subgrade . Driveway Approach Subgrade
. Curb and Gutter . Driveway Approach Aggregate Base
. Front Street and Western Bypass . Front Street and Western Bypass
Subgrade Aggregate Base
Maximum dry density/optimum moisture content tests were conducted on samples of the native
earth materials and imported aggregate base. The tests were performed in general accordance
with ASTM D 1557-91 (1998) procedures. The results are presented in the Appendix of this
,report. Relative compaction testing was performed in general accordance with ASTM D
2922-96 and ASTM D 3017-96 procedures for determining in-place density and moisture
content, respectively, using nuclear density gauge equipment. Test results are presented in the
Appendix and the approximate test locations are shown on the site plan, also presented in the
Appendix of this report.
In-place density test results indicate a minimum of 90 percent relative compaction for the
Sidewalk subgrade, the curb and gutter subgrade and trench backfill areas of the site, and 95
percent relative compaction for the driveway approach subgrade, Front Street and Western
Bypass subgrade, and in the aggregate base. The native soils encountered on the site
consisted of brown silty sand as well as dark brown sandy silt. Import earth materials consisted
of gray sandy gravel aggregate base.
Based on the observations and tests performed in the areas noted as test locations, the post
grading operation has been completed in accordance with the Referenced NO.1 Report and the
grading code of the City of Temecula, California.
