To City Building/Grading Officials:
In accordance with the City of Newport Beach building requirements, we are submitting this
compaction report for the grading of the subject building pad. This report includes the test
results performed at the subject lot during the placement of on -site soil material in the area of
the proposed residential building pad. The site earthworks operations were performed by the
sub -contractor, Tim Greenleaf Engineering, Inc.
Excavation and grading of the subject lot commenced on September 17, 2020 and was
complete by September 25, 2020. To date, site grading included the removal of the upper 3
feet of the old fill and native material located within the limits of the proposed building pad. The
lot was roughly divided into front and rear halves; excavated, and recompacted to bring the
entire lot to finished subgrade.
One Caterpillar 289D track loader was utilized for the purpose of compaction and grading
control. On site soils were moisture treated via a 2-inch diameter water hose during the grading
process to bring the moisture content to near -optimum. For cohesion -treatment, 3 (three)
pallets Portland Cement were blended into the newly -placed fill. Each pallet contains 40 bags
dry mix, each weighing 94 pounds and approximately 1.33 cubic yards.
Prior to the placement of fill, the excavation bottoms were inspected and approved by a
Certified Engineering Geologist employed by EGA Consultants. The exposed surface was
scarified, moisture conditioned and recompacted to a minimum of 90% relative compaction.
Field density test results are tabulated on Table 1, Summary of Field Density Tests.
All earthwork operations were performed under continuous observations by this firm and were
performed in accordance with geotechnical specifications outlined in the soils report by EGA
Consultants, Inc., dated May 17, 2019.
375-C Monte Vista Avenue • Costa Mesa, CA 92627 • (949) 642-9309 • FAX (949) 642-1290
The building pad was graded in accordance with the 2019 CBC and the City of Newport Beach
Building standards and are approved for construction. Based on our continuous observations
and testing, the subject and adjacent sites are not impacted by the site grading operations to
date.
This report includes the test results performed at the subject site during the placement of on -
site soil material in the area of the proposed building pad. Additional observations and
testing are required in areas to receive exterior improvements (driveway approach, patio
flatwork, etc.) capillary break, and utility trench backfill.
I certify that all rough grading work was done in compliance with the above -referenced Soils
Report and the work complies with City of Newport Beach grading regulations. All soils values
and geotechnical specifications outlined in the above -referenced soils report remain valid.
This opportunity to be of service is appreciated. If you have any questions, please call.

To City Building/Grading Officials:
In accordance with the City of Newport Beach building and grading requirements, we are
submitting this final compaction report for the grading of the subject building pad, utility trench
backfill, and exterior improvements. The site earthworks operations were performed by the sub-
contractor, Tim Greenleaf Engineering, Inc.
Excavation and grading of the subject lot commenced on September 17, 2020 and was
complete by September 25, 2020. All flatwork subgrade was completed by February 15, 2022.
Site grading included the removal of the upper 3 feet of the old fill and native material located
within the limits of the building pad.
Prior to the placement of fill, the excavation bottoms were inspected and approved by a
Certified Engineering Geologist employed by EGA Consultants. The exposed surface was
scarified, moisture conditioned and recompacted to a minimum of 90% relative compaction.
One CAT 289D track loader, a jumping jack Wacker, and vibratory plates were utilized for the
purpose of compaction and grading control. On site soils were moisture treated via a 2-inch
diameter water hose during the grading process to bring the moisture content to near -optimum.
For cohesion -treatment, 3 (three) pallets Portland Cement were blended into the newly -placed
fill. Each pallet contains 40 bags dry mix, each weighing 94 pounds and approximately 1.33
cubic yards.
