(Orion), at the request of Panattoni Development Company, Inc. (Panattoni), performed a Phase II Environmental Site Assessment (ESA) for the property located at 3100 Irvine Avenue in Newport Beach, California (Subject Property). The Subject Property consists of an approximately 15.4-acre parcel identified by Assessor’s Parcel Number (APN) 119-200-41 and is located in developed area of Newport Beach generally characterized by retail/commercial and residential properties. Currently the Subject Property is operated as a golf course that includes a driving range, three golf holes, a practice putting green, and a clubhouse with a restaurant. Unless otherwise noted, Orion conducted this Phase II ESA in general accordance with the scope and limitations of ASTM International (ASTM) Standard Practice for ESAs (ASTM E1903-19) (ASTM International, 2020). The purpose of the Phase II ESA was to (1) analyze shallow soil across the driving range and golf course for the potential presence of herbicides, pesticides, and metals and (2) assess potential impacts to shallow soil and groundwater at the Subject Property that may have resulted from the potential migration of per- and polyfluoroalkyl substances (PFAS) from a southeast-adjoining fire training center, which were identified as a recognized environmental condition (REC) and an environmental concern (EC) in Orion’s 2024 Phase I ESA, respectively. The scope of work included collecting soil samples at 32 locations including six locations on a driving range, nine locations on and around three golf holes, 12 locations on greens and tee boxes, two locations on a putting green, and three locations adjacent to a fire training center. Additionally, the collection of groundwater was attempted at one location. Soil sampling results indicated that there are no levels of herbicides, organochloride pesticides, and PFAS detected above laboratory reporting limits. Arsenic was the only metal above health risk screening levels for commercial/industrial land use, but did not exceed the background concentrations for trace and major elements in California soils. A grab groundwater sample was attempted at one boring located adjacent to the southeast- adjoining fire training center. However, refusal was encountered during drilling at approximately 75 feet below ground surface and groundwater was not encountered. Based on the lack of PFAS in shallow soil samples and the depth to groundwater at greater than 75 feet below the ground surface, the groundwater below the Subject Property is not likely impacted by PFAS from the fire training center. RI N S:\Clients\2024-0814 Phase II 3100 Irvine Avenue APN -41 ES-2 Based on the results of the Phase II ESA, there are no herbicides, organochloride pesticides, metals, or PFAS in the shallow soil that exceeds health risk screening levels. Orion recommends that no additional site assessment is warranted at the Subject Property at this time. The Executive Summary section of this report is only intended to represent a brief summary of findings and is not a detailed account of all the information documented in this report. The report should be reviewed in its entirety before drawing any final conclusions as to environmental conditions associated with the Subject Property.

The Subject Property consists of one parcel with an area of approximately 15.4 acres identified by Orange County APN 119-200-41 (Figure 2). The scope of work was conducted in general accordance with Orion’s proposal dated 29 April 2024 and approved by Panattoni on 8 May 2024. The following sections summarize the site background and Phase II ESA objectives and scope of work. 1.1 Site Background Orion performed a Phase I ESA and Tier I Vapor Encroachment Screening of the Subject Property in April 2024 (Orion, 2024). Based on Orion’s review of aerial photography, the Subject Property has been a golf course since the 1980’s. During site reconnaissance, ten 5-gallon containers of fungicide were observed in a maintenance area adjacent to the Subject Property and assumed to be applied as part of current golf course maintenance operations. During site reconnaissance, Orion observed a fire station and training center to the southeast of the Subject Property (Figure 3). Personnel at the Subject Property stated that fire suppression training had previously been observed at the training center. After completing the Phase I ESA, Orion identified a total of one REC and one area of environmental concern (EC) (Orion, 2024):  REC No. 1 – Historical Pesticide and Herbicide Application Fungicides are considered a type of pesticide used to prevent the growth of fungi and their spores. Golf courses are known to require heavy application of pesticides and herbicides and routine course maintenance may have resulted in a potential release of hazardous materials to shallow soils.  EC No. 1 – Potential Use of PFAS at Adjacent Property Personnel at the Subject Property stated that fire suppression training had previously been observed at the training center. Fire training activities are often associated with the application of PFAS-containing fire suppressants. The adjacent training center is located uphill and upgradient of the Subject Property. The use, and any potential releases, of PFAS-containing materials at the upgradient fire training center has the potential to impact the Subject Property. RI N S:\Clients\2024-0814 Phase II 3100 Irvine Avenue APN -41 1-2 Based on the results of the Phase I ESA, Orion recommended a Phase II ESA be conducted at the Subject Property to evaluate (1) the potential presence of herbicides, pesticides, and metals in shallow soil and (2) the potential presence of PFAS in shallow soil and groundwater on site originating from the upgradient fire training center. 1.2 Objectives and Scope of Work Unless otherwise noted, Orion conducted this Phase II ESA in general accordance with the scope and limitations of ASTM Standard E1903-19. The objectives of the Phase II ESA were to (1) analyze shallow soil across the driving range and golf course for the potential presence of herbicides, pesticides, and metals and (2) assess potential impacts to shallow soil and groundwater at the Subject Property that may have resulted from the potential migration of PFAS from the fire training center. To meet these objectives, Orion performed the following scope of work:  Mobilized for field activities including updating the site-specific Health and Safety Plan (HSP), coordinating access with the property owner, and obtaining a soil boring installation permit from Orange County Health Care Agency Environmental Health Division (OCHCA).  Marked boring locations and the property for Underground Service Alert (USA) and notified USA to mark underground utilities  Collected shallow soil samples at 32 locations and submitted samples for analysis to a California-certified laboratory  Advanced a soil boring at one location using a direct-push drill rig, collected soil samples, and submitted samples for analysis to California-certified laboratory  Backfilled borings with Portland cement grout and completed surfaces to match existing conditions in accordance with OCHCA procedures  Profiled and disposed of investigation-derived waste (IDW) in accordance with State and federal guidelines  Evaluated the field and analytical results and prepared this summary report. RI N S:\Clients\2024-0814 Phase II 3100 Irvine Avenue APN -41 2-1 2.0 SCREENING CRITERIA Orion evaluated the data collected as part of this Phase II ESA against several criteria developed by State and federal agencies to assess whether detectable concentrations pose a potential risk to human health or the environment. Orion used the soil criteria listed below for the purposes of this Phase II ESA.  Modified Screening Levels (SLs) for commercial/industrial land use published by the California Department of Toxic Substances Control (DTSC) Human and Ecological Risk Office (DTSC, 2020)  Regional Screening Levels (RSLs) for (1) commercial/industrial land use and (2) soil leaching to groundwater published by the U.S. Environmental Protection Agency (EPA; EPA, 2021)  Typical background concentrations of heavy metals in California soils. The DTSC SLs and EPA RSLs provide human health risk criteria for commercial/industrial land use based on dermal contact, ingestion, and inhalation. As a conservative measure, data were compared to the more stringent value of the human health risk screening levels. EPA RSLs for soil leaching to groundwater provide environmental risk criteria based on the potential for impacted soil to contaminate groundwater above risk-based RSLs. Typical background concentrations of naturally occurring metals in California soils were compiled and published in studies by the University of California Kearney Foundation of Soil Science and U.S. Geological Survey (Bradford et al., 1996; Shacklette and Boerngen, 1984). RI N S:\Clients\2024-0814 Phase II 3100 Irvine Avenue APN -41 3-1 3.0 PHASE II ESA PROCEDURES Orion conducted a Phase II ESA at the Subject Property to (1) analyze shallow soil across the driving range and golf course for the potential presence of herbicides, pesticides, and metals and (2) assess potential impacts to shallow soil and groundwater at the Subject Property that may have resulted from the potential migration of PFAS from the fire training center. Sampling locations are shown on Figure 4. Before beginning the field activities, Orion marked boring locations at the property and notified USA to mark underground utilities. In addition, Orion obtained a soil boring installation permit from OCHCA and a copy of the permit is in Appendix A. Field activities were performed in accordance with the site-specific HSP. The following sections summarize the soil and groundwater field sampling procedures executed as part of this Phase II ESA. 3.1 Soil Sampling Procedures On 28 May 2024, Orion collected soil samples from 32 locations (SB-1 through SB-14, SB-17 through SB-19, and CB-1 through CB-15) at the Subject Property as shown on Figure 4. Soil samples were collected using hand auger cuttings from approximately 0 to 1 foot bgs and 2 to 3 ft bgs at each location. Sampling locations were backfilled to the ground surface with native soil. Discrete soil samples were collected and submitted at each location for the three tee boxes, three greens, and one putting green at the golf holes (SB-1 through SB-14). Composite soil samples were collected from each of the areas of interest at the Subject Property including the fairways of the golf holes (CB-1 through CB-9) and the driving range (CB-10 through CB-15). Samples from each of the fairway locations were composited for each discrete depth into two samples per fairway for a total of six samples. Sample locations from the driving range were composited for each discrete depth into two samples for a total of 12 samples. Samples collected for vertical delineation from 2 to 3 ft bgs were placed on hold with the laboratory. Shallow soil samples were collected at three locations in the vicinity of the adjacent fire training center (SB-17 through SB-19). Soil samples were collected using hand auger RI N S:\Clients\2024-0814 Phase II 3100 Irvine Avenue APN -41 3-2 cuttings from approximately 0 to 1 foot and 2 to 3 ft bgs at each location for a total of six samples. Orion collected samples using unpreserved 8-ounce glass jars as well as Terra Core™ kits containing preserved bottles provided by the analytical laboratory. Soil sampling locations were backfilled to the ground surface with native soil. 3.2 Groundwater Sampling Procedures On 28 May 2024, Coreprobe International (Coreprobe) of San Gabriel, California, advanced one boring to collect groundwater near the southeast-adjoining fire training center (Figure 4). The boring was hand augered to 5 ft bgs to clear for subsurface utilities. Coreprobe advanced the soil boring using a direct-push type rig to a total depth of 75 ft bgs. Refusal was met at a depth of 75 ft bgs and the boring was terminated. Soil cores were collected at five foot intervals in acetate for visual logging. A temporary well was left for 24 hours at a depth of 75 ft bgs to collect groundwater, however, the temporary well was dry and no groundwater sample was collected. The temporary well was removed and the soil boring was decommissioned on 29 May 2024. In accordance with OCHCA procedures, Coreprobe backfilled the boring with Portland cement and bentonite grout and completed with soil at the surface to match existing conditions. Sampling locations are shown on Figure 4. Field activities were completed in general accordance with the field quality assurance/quality control (QA/QC) procedures in Appendix B. 3.3 Analytical Program A total of 42 soil samples were collected during the Phase II ESA and submitted to Positive Lab Service (Positive), a California-certified laboratory located in Los Angeles. Positive analyzed a total of 18 the soil samples for organochlorine pesticides (OCPs) by EPA Method 8081, chlorinated herbicides by EPA Method 8151, and California Code of Regulations Title 22 (Title 22) metals by EPA Methods 6010B and 7471A, and three of the samples for select PFAS by EPA Method 533/537M. RI N S:\Clients\2024-0814 Phase II 3100 Irvine Avenue APN -41 3-3 Laboratory analytical QA/QC procedures are described in Appendix B. Laboratory analytical reports and chain-of-custody forms are in Appendix C. 3.4 Waste Characterization and Disposal Solid wastes such as used personal protective equipment, paper towels, trash bags, and any other solid debris were collected for offsite disposal as municipal trash. IDW generated during the Phase II ESA consisted of soil cuttings generated during drilling. IDW was containerized in a labeled 55-gallon drum at the Subject Property and a composite soil sample was collected for IDW characterization. The composite waste sample was submitted to Positive and analyzed for VOCs, TPH, Title 22 metals, and OCPs. Laboratory analytical reports and chain-of-custody forms for IDW samples are in Appendix C. Belshire Environmental Services, Inc., a licensed waste transporter based in Foothill Ranch, California, transported the waste to a licensed facility for disposal. A waste manifest is attached in Appendix D. RI N S:\Clients\2024-0814 Phase II 3100 Irvine Avenue APN -41 4-1 4.0 PHASE II ESA RESULTS Results of soil samples collected during the Phase II ESA are summarized in the following sections. Soil analytical results for metals are in Table 1. Soil analytical results for herbicides and organochlorine pesticides are in Tables 2 and 3, respectively. Soil analytical results for PFAS are in Table 4. Laboratory analytical reports and chain-of-custody forms are in Appendix C. 4.1 Soil Sample Analytical Results Lithology encountered during Phase II ESA sampling activities generally consisted of clay with sand, silt with sand, and poorly graded sand to the maximum depth explored of 75 ft bgs. Soil cores were screened using a photoionization detector (PID) at approximately 5-foot intervals. PID readings were less than 6 part per million by volume for all soil screening readings and Orion personnel did not observe staining or odors. Field observations and screening results are summarized in the boring log in Appendix E. Various metals were detected in soil samples at the Subject Property at levels that were generally below applicable screening levels or levels consistent with naturally-occurring background conditions. Arsenic was the only metal detected above the health screening levels, but did not exceed background concentrations for trace and major elements in California soils (Table 1). All other soil metals concentrations were below regulatory human health risk screening levels for commercial/industrial land use. Chlorinated herbicides and organochlorine pesticides were not detected in soil above laboratory reporting limits or DTSC SLs in any of the surficial soil samples in any samples collected at the Subject Property (Table 2 and 3). Samples taken at the southeast corner of the site from borings SB-17, SB-18, and SB-19 were analyzed for PFAS with consideration to the recent fire suppression training conducted at the fire station adjacent to the property. All samples taken from borings SB-17, SB-18, and SB-19 at a depth of 1 foot did not have any detections above the laboratory reporting limit or health risk screening levels. For this reason, the deeper samples collected at each location were not analyzed. PFAS results are in Table 4. RI N S:\Clients\2024-0814 Phase II 3100 Irvine Avenue APN -41 5-1 5.0 SUMMARY AND CONCLUSIONS Orion performed a Phase II ESA for the property located at 3100 Irvine Ave in Newport Beach, California, that consisted of APN 119-200-41. The purpose of the Phase II ESA was to (1) analyze shallow soil across the driving range and golf course for the potential presence of herbicides, pesticides, and metals and (2) assess potential impacts to shallow soil and groundwater at the Subject Property that may have resulted from the potential migration of PFAS from the fire training center. The scope of work was conducted in response to one REC and EC identified in a previous Phase I from April 2024. The Phase II ESA included the collection of soil samples at 32 locations including six locations on a driving range, nine locations on and around three golf holes, 12 locations on greens and tee boxes, two locations on a putting green, and three locations adjacent to a fire training center. Additionally, the collection of groundwater was attempted at one location. The results of the Phase II ESA support the following observations and/or conclusions: 1. Soil concentrations of arsenic exceeded EPA RSLs but did not exceed background concentrations for trace and major elements in California soils at multiple sampling locations. All other heavy metals analyzed did not exceed RSLs. Therefore, concentrations of heavy metals in the soil do not appear to pose a threat to human health or the environment. 2. Soil herbicides, organochlorine pesticides, and PFAs results did not exceed laboratory detection limits or RSLs. These results indicate there is no likely release of these compounds at the property and a threat to human health or the environment is not present from these compounds. Based on the results of the Phase II ESA, no additional site assessment is warranted at the Subject Property at this time.

Health and Safety Orion Environmental Inc. (Orion) used a site-specific health and safety plan (HSP) with procedures that were followed by field personnel for equipment safety, medical surveillance, personal protection, air quality monitoring, exposure control, emergency response, and general work practices during field activities. Before beginning work at the site, a site safety meeting was conducted. Field personnel reviewed the HSP and signed the accompanying acknowledgment form before initiating field activities. Field personnel were required to comply with the HSP throughout performance of site assessment activities. Based on the site history and potential chemicals of concern, field activities were initiated in Level D personal protective equipment (PPE). Personal Decontamination Procedures At a minimum, field personnel followed the following decontamination procedures: 1. Wore appropriate gloves. 2. Washed hands thoroughly with soap and water. 3. Avoided unnecessary contact with potentially hazardous materials. The HSP was reviewed for site-specific personal decontamination procedures. Documentation Procedures Field personnel followed documentation procedures developed for site investigation work. The procedures served to (1) provide a record of the activities performed in the field and (2) permit identification of samples and tracking of their status in the field, during shipment, and at the laboratory. All documentation was recorded with waterproof ink. Hand Auger Soil Sampling Soil borings were advanced using a hand auger. When the sampling depth was reached, the auger was removed from the boring and a sampler lowered to collect the soil sample. Soil samples were retrieved from the core extracted by the hand auger. Field personnel collected a portion of the soil from core and placed in a resealable plastic bag, which was closed and allowed to equilibrate for approximately 10 minutes. The organic vapor levels in the headspace were measured using a PID. The same sample was visually examined, and the results of the visual observation and headspace reading were recorded. RI N S:\Clients\2024-0814 Phase II 3100 Irvine Avenue APN -41 Hand auger sampling locations were backfilled the same day with native soil. Soil Boring and Drilling Soil borings were advanced using a truck- or track-mounted Geoprobe sampling rig with direct-push technology. The drill rods and sampling equipment were advanced into the subsurface with hydraulic pressure and the percussion of a top-mounted impact hammer. Soil borings were advanced to the target sampling depths using a stainless-steel tip and 1.5-inch-diameter stainless steel rods. When the sampling depth was reached, a piston rod was removed from the boring and a sampler lowered to collect the soil sample. Soil samples were collected using a hollow 1-inch-diameter, 2-foot-long steel sample tube fitted with either (i) a 24-inch-long acetate sleeve or (ii) four brass tubes, each 1-inch diameter and 6-inches long. The sample tube was advanced into the undisturbed soil at the desired depth and then removed from the boring. Samples were generally collected at 5-foot intervals starting at 5 feet below ground surface. Immediately after the sampler was retrieved, it was placed on a portable field stand near the boring and the acetate sleeve or brass tubes were removed. An approximately 6- to 12-inch-long portion of the 24-inch acetate sleeve was cut in the field and capped with Teflon liners and PVC end caps. If brass tubes were used, the ends of one of the tubes was covered with Teflon liners and PVC end caps. A portion of the soil from one of the remaining tubes was extruded and placed in a resealable plastic bag, which was closed and allowed to equilibrate for approximately 10 minutes. The organic vapor levels in the headspace were measured using a PID of FID. The same sample was visually examined and classified based on the United Soil Classification System. Soil samples were examined for staining and odors. The results of the visual observations and headspace reading were recorded on the boring logs. Borings were backfilled the same day with cement/bentonite grout using the augers as a tremie pipe. Soil Sampling Soil samples were collected for laboratory analysis using containers provided by the analytical laboratory, including glass jars and Terra Core™ kits. The sample containers were labeled or marked and placed in a resealable plastic bag on ice in a cooler until delivery to the analytical laboratory. A permanent pen was used to complete the label or mark directly on the tube. The information recorded included project identification, sample number (including boring number and sample depth), date, time, and the initials RI N S:\Clients\2024-0814 Phase II 3100 Irvine Avenue APN -41 of the person preparing the samples. Standard chain-of-custody procedures were used during sample collection and delivery. Solid Waste Storage and Disposal Solid wastes such as used PPE, paper towels, trash bags, and any other solid debris were collected for disposal. If sampled soil was not a hazardous waste, then solid wastes were double-bagged using plastic trash bags and placed into solid waste dumpsters. The contents of the solid waste dumpsters were disposed of at an approved solid waste facility. Soil cuttings generated during investigation activities were stored in drums approved by the U.S. Department of Transportation. At the completion of field investigation activities, samples from the drums were collected and analyzed in accordance with the sampling plans. Once the analytical results were obtained, the Project Manager determined the appropriate disposal method for these wastes. Chain-of-Custody Records During sample collection, chain-of-custody records were completed before samples were packaged for shipment. One copy of these records was placed in the project file. A second copy accompanied samples during transportation to the laboratory. The individual in the analytical laboratory who accepted responsibility for samples signed and dated the chain-of-custody record. Analytical QA/QC Procedures Laboratory analytical QA/QC procedures included (1) preparing and analyzing laboratory samples to assess the performance of the analytical laboratory and (2) conducting data validation in accordance with the protocols described below. QA/QC samples prepared by the laboratory included method blanks, matrix spike and matrix spike duplicates, and laboratory control samples. The laboratory results were reviewed in general accordance with EPA guidelines for data validation. The data validation process included reviewing laboratory results for the following parameters:  Completeness of the data package  Compliance with EPA-required holding times  Agreement of dilution factors with reported detection limits  Percent recovery and relative percent difference results for matrix spike and matrix spike duplicate analyses  Percent recovery results for laboratory control samples.

FINAL REPORT This laboratory report may contain results for target analytes that are not currently certifiable by the California Environmental Laboratory Accreditation Program (ELAP). ELAP is the state agency that accredits environmental testing laboratories in Califomia<https.//www.waterboards.ca.gov/drinking_water/cert/ic/labs/index.html>. ELAP certification is required for laboratories that perform testing for regulatory purposes, such as drinking water, wastewater, hazardous waste, and ambient water<https.J/www.waterboards.ca.gov/drinking_water/certlic/labs/apply.html>. However, ELAP does not certify all analytes or methods that a laboratory may offer. Therefore, some of the target analytes in this report may not have been tested under ELAP-approved methods or quality control procedures. The results for these analytes are provided for informational purposes only and should not be usea for regulatory compliance or decision making. Please contact the laboratory if you have any questions or concerns about the report. Reviewed by: Ryan J.
