Dear Mr. Bernstein: In accordance with your request and authorization, we have provided geotechnical observation and field density testing services during construction of the basement-level building pad for the Clearwater at Newport Beach project. The geotechnical observation and field density testing services documented in this letter, were provided by Ninyo & Moore representatives during the overexcavation and re-compaction efforts performed between May 31, 2022 and June 22, 2022. Prior to the placement of fill, the exposed subgrade was scarified to a depth of approximately 6 inches or more, moisture-conditioned, and was re-compacted to be firm and competent. Subsequently, the engineered backfill was moisture conditioned to near optimum, placed in horizontal lifts, and was re-compacted to a relative compaction of 90 percent or more. Based on our observations and test results, it is our opinion that the proposed building pad was over excavated and re-compacted in general accordance with the reference project plans and soils report, and supplemental geotechnical recommendations provided by Ninyo & Moore. Our opinions are provided in accordance with the current practice and standard of care exercised by geotechnical consultants performing similar tasks in the project area. No warranty, expressed or Ninyo & Moore | Clearwater at Newport Beach , Newport Beach, California | 209537009 | July 19, 2022 implied, is made regarding our opinions and conclusions. We appreciate the opportunity to be of service on this project.

Ninyo & Moore, 2021, Geotechnical Evaluation, Newport Beach Senior Living Facility, 101 Bayview Place, Newport Beach, California, dated November 24. Dear Mr. Bernstein: In accordance with your request and authorization, we have provided field observation and field density testing services during earthwork operations for the Clearwater at Newport Beach project located at 101 Bayview Place in Newport Beach, California (Figure 1). This report presents the results of our geotechnical observation and field density testing services. Our scope of services included project coordination, laboratory testing of selected soil samples, and field density testing during the grading operations that pertain to the new building area. We also provided field density testing during the various general site fill, trench, and structural excavation backfill, as well as for the placement and compaction of subgrade, aggregate base, and asphalt concrete. The earthwork operations observed and tested by Ninyo & Moore were performed between April 22, 2022, and November 2, 2023. The asphalt concrete placement and compaction operations observed and tested by Ninyo & Moore were performed between August 24, 2023 and August 28th, 2023. EARTHWORK The initial phase of grading for the project generally included stripping, clearing, and exporting the debris generated from the project demolition activities. Summaries of the earthwork operation for the new building and other improvements on site are as follows: • Building Pad Area – Ground preparation consisted primarily of overexcavation, scarification, moisture conditioning, and recompaction. The areas to receive fill were observed and approved by Ninyo & Moore prior to further construction. The subgrade soils were scarified to a depth of 6 inches or more, moisture conditioned, and recompacted to be firm and competent prior to placement of the new fill. The material utilized for fill was generated from excavated on-site soils Ninyo & Moore | 101 Bayview Place, Newport Beach, California | 209537009 | December 22, 2023 2 and import materials from an offsite location, which were brought to near optimum moisture and compacted in approximately 6 to 8-inch lifts to 90 percent or more relative compaction in accordance with project plans and geotechnical recommendations provided by Ninyo & Moore. During the earthwork operations, any oversized rocks (3-inches or greater) were removed by hand or equipment. The compacted fill soil placed within the building area is considered a primary structural fill. • Fire Lane – Ground preparation consisted primarily of overexcavation, scarification, moisture conditioning, and recompaction. After excavation, the subgrade was scarified, moisture conditioned, and compacted to 90 percent or more relative compaction in accordance with the geotechnical report. Upon satisfactory compaction of the subgrade, aggregate base was placed and compacted to 95 percent or more relative compaction to the specified thickness to receive the base of asphalt concrete. The subgrade soil and aggregate base in considered a secondary structural fill. • General Site Areas – Ground preparation included overexcavation, scarification, and recompaction below the proposed subgrades prior to further construction and/or fill. The fill, backfill, subgrade, soil placed and/or compacted is considered a secondary structural fill, and is intended to support new concrete, landscaped areas. • Utilities – Utility improvements include excavation and installation for storm drain, sanitary sewer, water service, and dry utilities. The soil placed and/or compacted is considered a secondary structural fill. Our services were provided as scheduled and coordinated by the construction manager, W. E. O’Neil. We were generally on site on a periodic basis during the earthwork operations. The earthwork was performed using heavy earthmoving equipment, including a Case loader, skip loader, and a Caterpillar D6 dozer, a medium-sized vibratory roller, rubber-wheel loader with full bucket and wacker Rammax compactors, and a water truck. ASPHALT CONCRETE PAVING Upon completion of the earthwork in the fire lane, asphalt concrete base course (Greenbook Type III B3 PG 64-10) was placed in 4-inch layers. The asphalt concrete was compacted to 95 percent or more relative compaction. Our services were provided as scheduled and coordinated by the construction manager, W. E. O’Neil. We were generally on site on a daily basis during the asphalt concrete paving operations. The asphalt concrete paving was performed using an asphalt concrete paving machine, material transfer vehicle, and breakdown and finish rollers. FIELD AND LABORATORY TESTING In-place moisture and density tests of the compacted materials were performed in general accordance with the ASTM International (ASTM) 6938 (Nuclear Gauge method). The laboratory maximum dry density test results were performed in general accordance with ASTM D 1557. In-place density tests of compacted asphalt concrete were performed in general accordance with ASTM D2950 (Nuclear Gauge Method). The laboratory maximum density / unit weight test results were Ninyo & Moore | 101 Bayview Place, Newport Beach, California | 209537009 | December 22, 2023 3 performed in general accordance with ASTM D1560. Maximum density test results are presented in Table 1. The field density test results for compacted fill, sewer main, storm drain, utility main, subgrade, and aggregate base are summarized in Table 2. The field density test results for asphalt concrete are summarized in Table 3. The approximate locations of the field density tests are shown on Figure 2. The field density test results were used to evaluate the relative compaction of the fill materials and asphalt concrete. CONCLUSIONS Based on our observation and testing, it is our opinion that the earthwork and asphalt concrete paving operations observed and tested by Ninyo & Moore were performed in general accordance with the referenced geotechnical engineering report, dated November 24, 2021 and supplemental geotechnical recommendations provided by Ninyo & Moore. Our observations and testing indicate that the fill soils placed between April 22, 2022, and November 2, 2023, were compacted 90 percent or more (subgrade) and 95 percent or more (aggregate base) relative compaction utilizing test methods ASTM D 6938 and D 1557. The asphalt concrete placed between August 24, 2023 and August 28, 2023 was compacted to 95 percent or more relative compaction utilizing ASTM D2950 and ASTM D1560. LIMITATIONS The field and laboratory testing presented in this report have been conducted in general accordance with current practice and the standard of care exercised by geotechnical consultants performing similar tasks in this area. No warranty, expressed or implied, is made regarding the opinions expressed in this report. It is important to note that the precision of field density tests and the maximum dry density tests is not exact and variations should be expected.

Dear Mr. Bernstein: In accordance with your request and authorization, we have provided field observation and field density testing services during construction of the basement-level building pad for the Clearwater at Newport Beach project located at 101 Bayview Place in Newport Beach, California (Figure 1). This report presents the results of our geotechnical observation and field density testing services that pertain to the structural fills placed during the earthwork operations for the building. Our scope of services included project coordination, laboratory testing of selected soil samples, and field density testing during the building overexcavation and recompaction operations. The earthwork operations for the building pad observed and tested by Ninyo & Moore were performed between June 14, 2022, and June 22, 2022. EARTHWORK The initial phase of earthwork included stripping, clearing, and exporting the debris generated from the project demolition activities. In general, ground preparation within the building pad area consisted primarily of overexcavation, scarification, moisture conditioning, and recompaction. The areas to receive fill were observed and approved by Ninyo & Moore prior to further construction. The subgrade soils were scarified to a depth of 6 inches or more, moisture conditioned, and recompacted to be firm and competent prior to placement of the new fill. The material utilized for fill was generated from excavated on-site soils and import materials from an offsite location, which were brought to near optimum moisture and compacted in approximately 6 to 8-inch lifts to 90 percent or more relative compaction in accordance with the referenced project plans and geotechnical recommendations Ninyo & Moore | 101 Bayview Place, Newport Beach, California | 209537009 | October 3, 2022 2 provided by Ninyo & Moore. During the earthwork operations, any oversized rocks (3-inches or greater) were removed by hand or equipment. Our services were provided as scheduled and coordinated by the construction manager, W. E. O’Neil. We were generally on site on a periodic basis during the earthwork operations. The earthwork was performed using heavy earthmoving equipment, including a Case loader, skip loader, and a Caterpillar D6 dozer, a medium-sized vibratory roller, rubber-wheel loader with full bucket and wacker Rammax compactors, and a water truck. FIELD AND LABORATORY TESTING In-place moisture and density tests of the compacted materials were performed in general accordance with the ASTM International (ASTM) D 6938 (Nuclear Gauge method) and D 1556 (Sand Cone method). The laboratory maximum dry density test result was performed in general accordance with ASTM D 1557 and is presented in Table 1. The field density test results are summarized in Table 2. The approximate locations of the field density tests are shown on Figure 2. The field density test results were used to evaluate the relative compaction of the fill materials. We should note that field density tests for minor fills outside of the building pad are not shown. CONCLUSIONS Based on our observation and testing, it is our opinion that the earthwork operations observed and tested by Ninyo & Moore were performed in general accordance with the referenced geotechnical engineering report, dated November 24, 2021 and supplemental geotechnical recommendations provided by Ninyo & Moore. Our observations and testing indicate that the fill soils placed between June 14, 2022, and June 22, 2022, were compacted to 90 percent or more relative compaction utilizing test methods ASTM D 6938, D 1556, and D 1557. Nuclear gauge density testing was performed in conformance with P/BC 2017-28. The compacted fill soil placed within the building pad areas is considered a structural fill, and is intended to support foundations and interior slabs-on- grade. LIMITATIONS The field and laboratory testing presented in this report have been conducted in general accordance with current practice and the standard of care exercised by geotechnical consultants performing similar tasks in this area. No warranty, expressed or implied, is mad e regarding the opinions expressed in this report. It is important to note that the precision of field density tests and the maximum dry density tests is not exact and variations should be expected.
