"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.

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.
