(2023), Pavement Subgrade Evaluation, 1060 Auto Center Court, Carlsbad, California, MTGL Project No. 3280A02, Log No. 23- 0250, dated July 28. Dear Mr. Powell: This final soils report presents the results of earthwork observation and compaction testing performed by MTGL Inc. (MTGL) for the subject project. This report supplements the previously issued rough graded building pad compaction report referenced above (MTGL, 2022) and attached to this report. For a detailed description of earthwork operations within the building pad footprint, please refer to the above referenced report. Since the completion of rough grading of the building pad on February 3, 2022, field density testing was subsequently performed during shallow earthwork activities throughout the remainder of the AutoNation MTGL Project No. 3280A02 AutoNation BMW of Carlsbad MTGL Log No. 23-0267R Carlsbad, California August 23, 2023 Page 2 site on a periodic basis, as directed by your field representative, between February 7, 2022, through July 22, 2023. A field daily report was prepared by our soil technicians for each day of testing and a copy was provided to the jobsite superintendent. This report presents the methods and results of field and laboratory testing of soils during the project’s earthwork activities. Field density testing was performed by the direct transmission nuclear method, ASTM D6938/D2950 and sand cone method, ASTM D1556. The maximum density–optimum moisture relationship for the soil was established in the laboratory by the ASTM D1557 test method. The Bulk Specific Gravity and Density of Compacted Asphalt was tested in the laboratory by ASTM D2726. Areas with failed tests were either re-worked and retested, or later investigated and retested. A summary of all field and laboratory tests performed is attached to this report. It should be noted that the asphalt pavement subgrade at the northwestern corner of the site was observed to be pumping during a proof-roll test, and therefore the pumping subgrade materials were considered unacceptable. Subsequently, the contractor elected to pave over the area of pumping subgrade materials with aggregate base (AB) and asphalt concrete (AC). The pumping subgrade area was later investigated by removing the previously placed asphalt pavement and performing density testing of the subgrade materials with a nuclear gauge and a sand cone to evaluate the in-situ moisture and density. At the time of investigating the pumping subgrade area, the minimum relative compaction requirement for the pavement subgrade was thought to be 95% relative compaction. However, as recommended in the project geotechnical investigation report and as indicated on the project plans, the recommended minimum relative compaction for subgrade materials in the subject area is 90%. Therefore, the previously performed subgrade density tests in the area of observed pumping met the minimum relative compaction requirement of 90%. Lastly, we recommend an evaluation of the pavement surface be performed in 9 to 12 months, and again in 3 to 5 years, from the date of the subgrade evaluation letter report (MTGL, 2023) to ensure that the pavement subgrade materials are performing as intended. We have performed earthwork observations and field and laboratory testing as previously described and in accordance with the project specific recommendations outlined in the project geotechnical investigation report (GMU, 2019) and requirements of applicable plans, codes, ordinances, grading plans, and the approved grading permit GR2021-0005. All field and laboratory tests were performed in accordance with and met the project requirements. No other warranty, expressed or implied, is made.

Commercial Development Resources (2020), BMW of Carlsbad Grading Plan, 1060 Auto Center Ct, Project No. CRP 2019-0013. 1. INTRODUCTION a. The purpose of this report is to present the results of geotechnical observation and testing services provided by MTGL, Inc. during rough grading of the building pad for proposed AutoNation BMW of Carlsbad facility located at 1060 Auto Center Court in Carlsbad, California. b. This report covers our observation and testing services conducted during the period of January 3, 2022 through February 3, 2022. 2. PROJECT DESCRIPTION a. The project consisted of preparing the rough graded building pad for a new approximate 65,350 square feet two-story building with roof level parking. The structure will be constructed with a slab-on-grade floor. AutoNation MTGL Project No. 3280A02 AutoNation BMW of Carlsbad MTGL Log No. 22-0154 Carlsbad, California February 15, 2022 Page 2 b. MTGL, Inc. provided geotechnical observation and testing services during the current site grading operation for the proposed building pad. Reports detailing grading operations for project pavement areas and infrastructure construction operations will be provided under separate cover. 3. GRADING AND EARTHWORK a. Prior to the start of site grading, existing improvements, pavements, slabs, utility lines, vegetation, and other debris were removed from the proposed building site. b. The building pad was overexcavated and brought to rough subgrade elevation with onsite soil materials under the observation and testing of our field representative. The building pad was overexcavated to a minimum depth of 8 feet below existing ground elevation and into competent native materials in accordance with referenced geotechnical report and project specifications. Overexcavation was done using a PC 490 excavator. The surface exposed by the overexcavation was scarified to a minimum depth of 8 inches, moisture conditioned with a firehose attached to a fire hydrant and compacted to a minimum 90% relative compaction utilizing a WA 480 front end loader. c. Fill materials consisted of native onsite soils classified as silty sand by the Unified Soils Classification System. These materials are coarse grained, non-plastic, and non-expansive in nature and are essentially the same materials as those encountered in the referenced geotechnical engineering report. d. The over excavation limits extended a minimum 5 feet outside the building footprints and the engineered backfill was moisture conditioned and compacted to the minimum requirement of 90 percent of the maximum dry density. e. The laboratory maximum density and optimum moisture content of the soils utilized in the project grading and construction operations were determined in accordance with ASTM D 1557 (Method A) test procedure. Test results are reported in attached Appendix A in Table 1. AutoNation MTGL Project No. 3280A02 AutoNation BMW of Carlsbad MTGL Log No. 22-0154 Carlsbad, California February 15, 2022 Page 3 4. TESTING 4.1 Field Procedures a. The subgrade soils were tested by our soil technicians. Results of the field density testing are presented in Appendix B on Table 2. b. Samples considered representative of field conditions were obtained for laboratory testing consisting of Maximum Dry Density & Optimum Moisture Content. 4.2 Methods of Tests Field density testing was performed by the direct transmission nuclear method, ASTM D 6938. The maximum density optimum moisture relationship for the soil was established in the laboratory by the ASTM D 1557 test method. 4.3 Records A Field Daily Report was prepared by our soil technician for each day of observation and testing. The reports were reviewed by our Engineer and are complementary to this report. 5. CONCLUSIONS Based on our observations and tests, it is considered that the geotechnical engineering aspects of the grading was performed in conformance with the approved geotechnical report, the project s construction documents, and the requirements of the City of Carlsbad. The building pad is deemed suitable for the support of the proposed structure. 6. RECOMMENDATIONS The soils encountered during grading are essentially the same materials as those described in the referenced geotechnical report (Reference 1). The structure should be constructed in accordance with the soil bearing values and recommended geotechnical design parameters contained within the referenced geotechnical report.

On July 11, 2023, an MTGL soil inspector cored the pavement, removed the aggregate base, and observed and probed the finished subgrade, which was found to be firm an unyielding and not excessively moist. On July 19, 2023, an MTGL licensed civil engineer observed the pavement in the area in question. There were no cracks observed in the pavement. A minor, low-severity local depression was observed, which can be explained by the paving over pumping subgrade. On July 21 and 22, 2023, an MTGL soil inspector performed nuclear gauge density tests in small areas where the pavement had been removed. Additionally, sand cone tests were performed for more reliable in-situ density and moisture contents. Finally, subgrade material was taken in one location and a maximum density-optimum moisture test was performed per ASTM D1557. One location met the specified relative compaction, two locations were deficient by 1% of the specified relative compaction, and one location was deficient by 2% of the specified relative compaction. Moisture contents at the cored locations were not excessive. The daily field reports for each of the day’s activities documented above are attached to this letter, as well as the ASTM D1557 laboratory test report. Page 1 of 2 AutoNation AutoNation BMW of Carlsbad Carlsbad, California MTGL Project No. 3280A02 MTGL Log No. 23-0250 July 28, 2023 Page 2 of 2 Based on our evaluation, the pavement subgrade appears to be suitable for pavement support as evidenced by the pavement observed was performing satisfactorily. No remedial measures are recommended at this time. To ensure the pavement subgrade is performing as intended, an evaluation of the pavement should be performed in 9 to 12 months, and again in 3 to 5 years to check if medium or high severity distresses materialize. If so, remedial measures will be warranted and recommended at that time. We appreciate this opportunity to be of continued service to you on this project. Should you have any questions regarding this report, please do not hesitate to contact us at your convenience. Respectfully Submitted, MTGL, Inc. Daniel Richardson, P.E.
