EXECUTIVE SUMMARY PSI has conducted a Limited Site Investigation at the property located at 745 Park Avenue N, Renton, WA 98057 (subject property). The subject property is located south of N 8th Street, between Logan Avenue N and Park Avenue N. The site is also defined by the King County Assessor as Parcel Number 088661-0010. Currently, the subject property is a 13.71-acre parcel of undeveloped land with heavily deteriorated paved parking areas (Figure 1). Adjacent properties consist of N 8th Street, followed by a retail shopping center to the north; Boeing business offices to the south; Logan Avenue N followed by the Boeing factory facility to the west; and Park Avenue N followed by paved parking areas to the east. Historically, the subject property was undeveloped wetlands from at least 1897 to the mid-1940s when Boeing developed the site and surrounding area into an aircraft development and manufacturing facility. Historical documentation reviewed by PSI indicates that the former subject property buildings, known as the “10-80 Buildings”, were used as storage areas, offices, and photograph development labs. Four ASTs and a UST containing diesel fuel were located on the western portion of the subject property. The UST was decommissioned in 1987. All buildings and ASTs were removed from the subject property by 2011. PSI reviewed Phase I ESA and Phase II ESA reports for assessments previous performed at the property by Golder to define potential impacts to the site. Findings of the Phase II ESA were as follows: • A regulatory exceedance of vinyl chloride in groundwater ranging from 0.9 μg/L to 3.2 μg/L was present in five sampling locations on the northwest portion of the subject property. The Department of Ecology cleanup level for vinyl chloride is 0.2 μg/L. Additionally, a regulatory exceedance of benzene and trichloroethene was detected at one sample location. • The soil vapor investigation indicated a regulatory exceedance of VOCs (1,2,4-trimethylbenzene, 1,3-butadiene, benzene, chloroform, and vinyl chloride) was present at the northwest portion of the subject property. Eight direct-push borings (B-1 through B-8) were advanced at the project site (Figure 2). Boring B-1 was located in the northwest portion of the subject property near the previously existing monitoring wells. Borings B-2 and B-3 were located near the former UST location in the southwest portion of the subject property. Boring B-4 was located in the center of the subject property. Boring B-5 was located on the southeast portion of the subject property. Borings B-6 and B-7 were located along the eastern side of the subject property. Boring B-8 was located in the northeast central portion of the subject property. Soil lithology in borings was observed to consist of sand, silt, and clay to a maximum depth of 10 feet below ground surface (ftbgs). Soils were screened for volatile organic compounds (VOCs) using a photoionization detector (PID); PID readings were non-detect in all borings. Groundwater was encountered in borings B-1 (4.9 ftbgs), B-2 (6.11 ftbgs), B-4 (6.27 ftbgs), and B-8 (4.9). Additionally, four soil-vapor probes (SG-1 through SG-4) were advanced on the eastern portion of the project from north to south across the property in the area of the future building footprint. Project Number: 0581204-2 Phase II: Limited Site Investigation Report June 11, 2018 Page 3 Soil samples were collected at 5 and 10 ftbgs to characterize site conditions. Select soil samples were transported to Environmental Services Network (ESN) of Olympia, WA, under chain of custody, and analyzed for the following: • Diesel and Heavy-Oil Range Petroleum Hydrocarbons • Volatile Organic Compounds (VOCs) • Polyaromatic Hydrocarbons (PAHs) The results of the investigation are summarized below: • 1,2-Dichloroethane (EDC) was detected above laboratory reporting limits in soil-gas from boring SG-1 at 0.69 μg/m3, however this detection is below the applicable Model Toxics Control Act (MTCA) Method B screening levels of 3.2 μg/m3. Remaining soil-gas constituents were not detected above laboratory reporting limits. • Diesel and oil range hydrocarbons were not detected above laboratory reporting limits in soil and groundwater. • VOCs were not detected above laboratory reporting limits in soil, groundwater. • PAHs were not detected above laboratory reporting limits in soil, groundwater. Based on the results of the soil, groundwater, and soil-gas sampling being below laboratory reporting limits and MTCA screening levels, PSI recommends no additional investigation at this time. Prior to the start of construction activities, the six on-site monitoring wells should be permanently abandoned in accordance with state regulations. This report must be read in its entirety to obtain a more accurate understanding of the information provided and aid in any decisions made or actions taken based on this information. Project Number: 0581204-2 Phase II: Limited Site Investigation Report June 11, 2018 Page 4 2. INTRODUCTION Professional Service Industries, Inc. (PSI) has conducted a Limited Site Investigation at the project site (Figure 1). This report documents the scope of work, field investigation activities, laboratory analyses, evaluation of the data, and conclusions. 2.1 Authorization This assessment was performed for Topgolf USA in accordance with the contract titled, Additional Services for Limited Site Investigation, dated May 4, 2018. 2.2 Site Description The subject property is located south of N 8th Street, between Logan Avenue N and Park Avenue N. The site is also defined by the King County Assessor as Parcel Number 088661-0010. Currently, the subject property is a 13.71-acre parcel of undeveloped land with heavily deteriorated paved parking areas. Geology Based upon a review of available geologic information and field observations (see boring logs), the site is underlain by sand, silt, and clay, which is generally described as light brown to light gray silt, clay, and fine to medium grained sand. Groundwater Based on the findings of this investigation, groundwater is approximately 5 to 10 ftbgs. 2.3 Project Background In April 2018, a Phase I ESA was performed by PSI for the project site. The findings identified by the Phase I ESA are as follows: • A regulatory exceedance of vinyl chloride in groundwater ranging from 0.9 μg/L to 3.2 μg/L was present in five sampling locations on the northwest portion of the subject property. The Department of Ecology cleanup level for vinyl chloride is 0.2 μg/L. Additionally, a regulatory exceedance of benzene and trichloroethene was detected at one sample location. More recent groundwater sampling indicates the concentrations of vinyl chloride in groundwater are now below analytical detection limits. • The soil vapor investigation indicated a regulatory exceedance of VOCs (1,2,4-trimethylbenzene, 1,3-butadiene, benzene, chloroform, and vinyl chloride) was present at the northwest portion of the subject property. Project Number: 0581204-2 Phase II: Limited Site Investigation Report June 11, 2018 Page 5 2.4 Purpose and Scope of Services The purpose of this Limited Site Investigation is to assess potential impact of soil-gas on the proposed Topgolf building as well as to confirm prior findings and verify the absence of soil and groundwater impact. Based on the Phase I ESA, PSI developed a scope of work for this Limited Site Investigation. The general scope consists of the following: advance borings in the areas of the former USTs, in the general center of the subject property, and along the east and southeast property boundary and collect soil and groundwater samples; advance soil-gas sample borings in the area of the proposed Topgolf building footprint; and access and sample from existing groundwater monitoring wells onsite. 2.5 Quality Assurance/Quality Control Measures Field decontamination and sampling procedures were performed in general accordance with the Oregon DEQ document titled, PA/SI Quality Assurance Project Plan. Downhole equipment utilized during the field activities was decontaminated prior to and between each soil boring. Decontamination of downhole equipment was accomplished by washing the equipment with a detergent solution and rinsing with water. Single-use disposable gloves were used for each sampling point to help prevent cross-contamination between sampling locations. Laboratory analytical procedures were performed by ESN. The laboratory performed standard data validation and quality control. 3. SUBSURFACE EXPLORATION Prior to drilling, utilities were marked by the respective utility companies where the utilities entered or were located adjacent to the site. In addition, a private utility locating company, CNI Locates, was contracted to investigate the presence of utilities near the proposed boring locations as well as the presence of a possible UST in the southwestern portion of the subject property. CNI Locates found evidence of a possible backfilled pit, however no evidence of USTs remaining in the southwestern portion of the subject property could be determined. 3.1 Soil Assessment Activities On May 24, 2018, PSI directed ESN to advance eight soil borings using a truck-mounted direct-push drill rig (Figure 2). Boring B-1 was located in the northwest portion of the subject property near the previously existing monitoring wells. Borings B-2 and B-3 were located near the former UST location in the southwest portion of the subject property. Boring B-4 was located in the center of the subject property. Boring B-5 was located on the southeast portion of the subject property. Borings B-6 and B-7 were located along the eastern side of the subject property. Boring B-8 was located in the northeast central portion of the subject property. Boring B-3 was advanced to a depth of 5 ftbgs where it entered a catch basin pipe not detected by ground penetrating radar (GPR). The remaining borings were advanced to depths of 10 ftbgs. Upon completion of the investigation, the borings were backfilled with bentonite chips and hydrated, in accordance with applicable regulations, and resurfaced to approximately match the surrounding grade. Project Number: 0581204-2 Phase II: Limited Site Investigation Report June 11, 2018 Page 6 During drilling, soil samples were screened for volatile organic compounds (VOCs) using a photoionization detector (PID). Boring logs were prepared to record visual observations of soil and PID readings (Appendix A). One soil sample were collected from each boring. Eight soil samples were collected into laboratory supplied containers and placed in a cooler with ice. Samples were transported under chain-of-custody protocol to ESN in Olympia, WA for the analyses. 3.2 Groundwater Assessment Activities On May 3, 2018, PSI collected representative groundwater samples from boring B-1 and B-2. Prior to sampling, the static water level was gauged. Following water level gauging, the borings were sampled using a low-flow peristaltic pump with dedicated polyethylene tubing. Additionally, PSI accessed and collected representative groundwater samples from the previously existing monitoring wells MW-1, MW-2, MW-3, and MW-4 (Figure 2). Prior to purging and sampling wells, the static water level was gauged using an electronic water level meter. Following water level gauging, all wells were purged and sampled using a low-flow peristaltic pump with dedicated polyethylene tubing. Well purging was considered complete when a minimum of approximately three casing volumes were removed from the well. Six groundwater samples were collected into laboratory supplied containers and placed in a cooler with ice. Samples were transported under chain-of-custody protocol to ESN for analysis. 3.3 Soil-Gas Assessment Activities On May 24, 2018, PSI directed ESN to advance four soil-gas borings using a truck-mounted direct-push drill rig (Figure 2). All soil-gas probes were advanced to 5 ftbgs. The soil-gas samples were collected in Summa Canisters and transported under chain-of-custody protocol to Eurofins Air Toxics, Inc. (Eurofins) of Folsom, California. 4. LABORATORY ANALYSES AND DATA INTERPRETATION Analyses and interpretation of the data generated from the field investigation are presented in the following sections, and where appropriate, results are compared to regulatory limits. Seven soil samples from 10 ftbgs and one soil sample from 5 ftbgs were selected for laboratory analyses. Select soil samples were analyzed by ESN for the following: • Diesel and Heavy-Oil Range Petroleum Hydrocarbons by Method NWTPH-Dx/Dx Extended • VOCs by Method 8260C/5035 • PAHs by Method 8270 Project Number: 0581204-2 Phase II: Limited Site Investigation Report June 11, 2018 Page 7 Six groundwater samples were selected for laboratory analyses. Select groundwater samples were analyzed by ESN for the following: • Diesel and Heavy-Oil Range Petroleum Hydrocarbons by Method NWTPH-Dx • VOCs by Method 8260 • PAHs by Method 8270 Four soil-gas samples were selected for laboratory analyses. Soil-gas samples were analyzed by Eurofins for VOCs by Method TO-15. 4.1 Laboratory Results Soil Sampling Laboratory Results Laboratory analyses did not detect diesel and heavy-oil range hydrocarbons, VOCs, or PAHs in soil samples above laboratory reporting limits. Groundwater Sampling Laboratory Results Laboratory analyses did not detect diesel and heavy-oil range hydrocarbons, VOCs, or PAHs in groundwater samples above laboratory reporting limits. Soil-Gas Sampling Laboratory Results 1,2-Dichloroethane (EDC) was detected above laboratory reporting limits in soil-gas collected from SG-1 at 0.69 μg/m3, however this detection is below the MTCA Method B screening level of 3.2 μg/m3. Remaining soil-gas constituents were not detected above laboratory reporting limits. Select laboratory data is tabulated in Tables 1 and 2. A complete copy of the laboratory report and chain of custody documentation are included in Appendix B. 5. CONCLUSIONS AND RECOMMENDATIONS Based on the results of the soil, groundwater, and soil-gas sampling being below laboratory reporting limits and MTCA screening levels, PSI recommends no additional investigation at this time. Prior to the start of construction activities, the six on-site monitoring wells should be permanently abandoned in accordance with state regulations.

at a level less than five times the reporting limit. The RPD results may not provide reliable information on the variability of the analysis. b - The analyte was spiked at a level that was less than five times that present in the sample. Matrix spike recoveries may not be meaningful. ca - The calibration results for the analyte were outside of acceptance criteria. The value reported is an estimate. c - The presence of the analyte may be due to carryover from previous sample injections. cf - The sample was centrifuged prior to analysis. d - The sample was diluted. Detection limits were raised and surrogate recoveries may not be meaningful. dv - Insufficient sample volume was available to achieve normal reporting limits. f - The sample was laboratory filtered prior to analysis. fb - The analyte was detected in the method blank. fc - The compound is a common laboratory and field contaminant. hr - The sample and duplicate were reextracted and reanalyzed. RPD results were still outside of control limits. Variability is attributed to sample inhomogeneity. hs - Headspace was present in the container used for analysis. ht – The analysis was performed outside the method or client-specified holding time requirement. ip - Recovery fell outside of control limits. Compounds in the sample matrix interfered with the quantitation of the analyte. j - The analyte concentration is reported below the lowest calibration standard. The value reported is an estimate. J - The internal standard associated with the analyte is out of control limits. The reported concentration is an estimate. jl - The laboratory control sample(s) percent recovery and/or RPD were out of control limits. The reported concentration should be considered an estimate. js - The surrogate associated with the analyte is out of control limits. The reported concentration should be considered an estimate. lc - The presence of the analyte is likely due to laboratory contamination. L - The reported concentration was generated from a library search. nm - The analyte was not detected in one or more of the duplicate analyses. Therefore, calculation of the RPD is not applicable. pc - The sample was received with incorrect preservation or in a container not approved by the method. The value reported should be considered an estimate. ve - The analyte response exceeded the valid instrument calibration range. The value reported is an estimate. vo - The value reported fell outside the control limits established for this analyte. x - The sample chromatographic pattern does not resemble the fuel standard used for quantitation.
