CITY OF NEWPORT BEACH February 23, 2018
Building Department Project No. EM861.2
100 Civic Center Drive
Newport Beach, CA 92660
Subject: COMPACTION REPORT FOR PLACEMENT OF FILL
WITHIN LIMITS OF RESIDENTIAL BUILDING PAD AT
2404 WEST OCEANFRONT
NEWPORT BEACH, CALIFORNIA
City of Newport Beach Permit No.: 2361-2016
References:
1. "Geotechnical Investigation for Proposed Residential Development Located at 2404 West Oceanfront, Newport Beach,
California," by EGA Consultants, Inc., dated May 28, 2015.
2. 'Response to City Comments Dated 11/14/16 for Proposed Residential Development Located at 2404 West Oceanfront,
Newport Beach, California," by EGA Consultants, Inc., dated May 23, 2017.
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, JD Demolition and Grading, Inc.
Excavation and grading of the subject lot commenced on January 25, 2018 and was complete
by February 15, 2018. To date, site grading included the removal of the upper 2'/z feet of the
old fill and native material located within the limits of the proposed building pad. The lot was
roughly divided into halves, excavated and recompacted to bring the entire lot to finished
subgrade.
One Bobcat S130 front loader was utilized for the purpose of compaction and grading control.
On site soils were below optimum moisture content, therefore water was added during the
grading process to bring the moisture content to near -optimum.
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 dated May
28, 2015.
The building pad was graded in accordance with the 2016 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.
375-C Monte Vista Avenue • Costa Mesa, CA 92627 • (949) 642-9309 • FAX (949) 642-1290
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.) 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.

scarification) of the old fill and native material located within the limits of the proposed building
pad and exterior improvements. All flatwork subgrade was completed by June 13, 2019.
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. For
cohesion -treatment, four (4) pallets of Portland Cement were blended into the newly -placed fill.
Field density test results are tabulated on Table 1, Summary of Field Density Tests.
One Bobcat S130 front loader, one jumping -jack Wacker, one vibratory plate, and water hoses
were utilized for the purposes of compaction and grading control. All earthwork operations
were performed under continuous observations by this firm and were performed in accordance
with geotechnical specifications outlined in the soils report dated May 28, 2015.
