The cost of these additional services is included in the overall project budget and staff is not asking for additional budget authority. BACKGROUND Note, in response to the CSS meeting on August 10, 2020, staff has provided a new memo with additional detail. The original memo is included as an attachment. The City of Tukwila hired SoundEarth Strategies, Inc. to perform Environmental Site Assessment (ESA) services in connection with the Tukwila Public Safety Plan. ESA services involve two phases: Phase I is the background research of potential contamination and Phase II is the site exploration, including field work and soils testing. The initial contract provided Phase I services related to the Justice Center (JC) and Fire Station 52 (FS52) sites. The Phase I ESA Report (September 2017) research identified several Recognized Environmental Conditions (RECs) on the JC property. These included historical operations of a retail gasoline service station, an automotive repair facility, and use and storage of heating oil for oil -burning furnaces. It also identified several RECs on neighboring properties, including historical operations of dry cleaners, retail gasoline service stations, an automotive repair and service station, a vehicle maintenance garage, a welding facility, a print shop, and a cabinet shop. The results of the Phase I were expected given the site's location on a major transportation corridor and with the previous light industrial, commercial and residential uses of the property, including automobile -oriented uses. These site characteristics are similar to other properties in the Tukwila International Blvd or Interurban Corridor areas. On December 7th, 2017, Amendment No. 1 added Phase I and II services to the Public Works (PW) site, Phase II for the Justice Center site and Phase I the Fire Station 54 (FS54) site, in the amount of $111,937. The purpose of the Phase II ESA was to evaluate the potential for below - ground environmental impacts from RECs identified in the Phase I ESA. Phase II field work included installing 15 soil borings, 4 groundwater monitoring wells, and use of ground -penetrating radar (GPR) to detect underground storage tanks (USTs). The Phase II Report (January 2019) concluded that gasoline -range petroleum hydrocarbons (GRPH) and benzene were present in soil and possibly groundwater beneath the former service station. Because the samples tested Tukwila City Hall ■6200 So threat outevard • Tukwila, WA 77 exceeded required cleanup levels, this report confirmed that the JC site contained contamination that would need to be remediated during construction. The Phase II investigation included GPR to locate USTs. No USTs were detected initially, but the report noted that there was a strong possibility of encountering an unregistered UST during the course of redevelopment. Doing further investigation to confirm the absence of USTs did not seem practical given that the costs of doing the reconnaissance work could equal or exceed the cost of remediation. Further, soil impacts due to unregistered USTs may have remained undiscovered even if the number of soil borings was increased. On March 26, 2018, Amendment No. 2 added Phase II services to Fire Station 52 and 54, as well as some additional services needed for soils testing on the Justice Center site, in the amount of $36,325. On May 11th, 2018, Amendment No. 3 called for additional Due Diligence services; however, these were covered by previously approved contingency plus reallocating funds previously allocated to soils testing work on Fire Station 54, which were no longer needed. Therefore, the contract amount did not increase. On December 26th, 2018, Amendment No. 4 changed the duration of the contract, extending it to December 31, 2019. On March 26, 2019, Amendment No. 5 added remedial excavation and field support activities during construction, in amount of $85,770. In November of 2019, Amendment No. 6 added additional remedial excavation, field support and tank removal activities, in the amount of $73,000, bringing the not - to -exceed amount to $322,032. As anticipated based on the Phase I and II reports, the project encountered significant volumes of contaminated soil during site excavation and redevelopment, primarily at the former gas station location (NE portion of south parcel). Six USTs associated with the former gas station and residential and commercial oil -burning furnaces were also encountered throughout the properties. Again, these were not a surprise given historical uses, but the exact quantities and location were not known until excavation work, as is typical. The USTs were properly decommissioned and removed, including any contaminated soil associated with them. Nearly all contaminated soil encountered during construction was removed and disposed of off -site and clean backfill imported in its place. There were a few exceptions where it was not practical or feasible to remove all contaminated soil. In such instances, the remaining soil was capped in place and documented for the potential Environmental Covenant process consistent with SoundEarth's Soil Management Plan and best practices. The project budget included appropriate contingencies to cover the costs of these expected but not fully defined contaminated soil and USTs encountered during construction. ANALYSIS Amendment No. 7 is to add services to perform a supplemental subsurface investigation at the Justice Center site to evaluate groundwater conditions in the vicinity of the observed soil impacts of the Property by installing nine (9) groundwater monitoring wells and conducting sampling of the wells. The installation and sampling of these groundwater monitoring wells are required by the Washington State Department of Ecology and thus the appropriate next step in the site remediation process. Following the initial groundwater sampling, SoundEarth will complete a Cleanup Action Report, which will include a summary of all the soil and groundwater sampling results and will be submitted to Ecology and/or the Pollution Liability Insurance Agency (PLIA) in Phone: 206-433 800 • Email: ayor Tukwil iA,g v !brie Tukwila WAb ov 78 pursuit of a No Further Action (NFA) determination for the JC site. These are anticipated expenditures and are included in the Council -approved project budget. FISCAL IMPACT SoundEarth Strategies has provided a proposal of $60,105 to complete this scope of work.

(SoundEarth) appreciates the opportunity to provide you with this work plan to conduct additional investigation of impacts present beneath the JC7NL Property, located at the address listed above in Tukwila, Washington (the Property). PROPOSED SCOPE OF WORK It is our understanding that City of Tukwila is requesting that SoundEarth perform a supplemental subsurface investigation at the Property to evaluate groundwater conditions in the vicinity of the observed soil impacts of the Property by installing nine monitoring wells across the Property. To that end, SoundEarth has proposed the following scope of work. Task 1, Scope of Work Development, Permitting, and Pre -Field Activities. This task includes conducting public and private utility locates, coordinating with the laboratory and other subcontractors, and preparing and coordinating field staff for each phase of field work. Based on the extents of the soil contamination identified during the excavation, at least one well will need to be located in the South 105th Street right-of-way. This task includes securing a street use permit and preparing a traffic control plan for the well install. Costs associated with obtaining a street use permit are included in the attached estimate. Task 2, Monitoring Well Installation. In an effort to evaluate groundwater conditions in the vicinity of observed soil impacts during the redevelopment excavation and to assess whether the soil impacts have resulted in impacts to groundwater, SoundEarth will advance nine hollow -stem auger borings at exterior locations on the Property. The borings will be completed as monitoring wells and will be properly developed before sampling to ensure that a representative groundwater sample is collected. Drilling activities will be completed using a truck -mounted hollow -stem auger drill rig. The soil borings will be advanced to a depth of approximately 20 to 25 feet below ground surface (bgs), depending on groundwater conditions observed during drilling. Soil samples will be collected at approximate 5-foot intervals and described in general accordance with the Unified Soil Classification System by a SoundEarth geologist. Soil samples will be screened in the field for potential evidence of contamination by using visual t y r.,st ondoariIiIrrt° c dodo Eb.tt° k1,l'9[dd 'Always do riujidt.. ��lil� �,r,riuti pruEktF. 83 EXHIBIT A City of Tukwila July 29, 2020 observations and notations of odor and by conducting headspace analysis using a photoionization detector to detect the presence of volatile organic vapors. Based on the results of field screening, up to three soil samples will be submitted to the laboratory for one or more of the following analyses: ■ Gasoline -range petroleum hydrocarbons (GRPH) by Northwest Total Petroleum Hydrocarbon (NWTPH) Method NWTPH-Gx ■ Diesel -range petroleum hydrocarbons (DPRH) and oil -range petroleum hydrocarbons (ORPH) by Method NWTPH-Dx • Benzene, toluene, ethylbenzene, and total xylenes (BTEX) by US Environmental Protection Agency (EPA) Method 8021B ■ Resource Conservation Recovery Act 8 metals using EPA Method 200.8/6020A After completion of the soil borings, monitoring wells will be installed and screened at a depth interval to be determined based on field observations of groundwater. Groundwater is expected to be encountered at a depth of 15 to 20 feet bgs, based on SoundEarth's initial subsurface investigation. The monitoring wells will be constructed of 2-inch-diameter blank PVC casing, flush -threaded to 0.010-inch slot well screen. The bottom of the well will be fitted with a threaded PVC bottom cap, and the top of the well casing will be fitted with a locking compression -fit well cap. The annulus of the monitoring wells will be filled with #10/20 silica sand to a minimum height of 1 foot above the top of the screened interval, and a bentonite seal with a minimum thickness will be installed above the sand pack. The monitoring wells will be completed with a flush -mounted, traffic -rated well box set in concrete. Following installation, the monitoring wells will be developed with the use of a submersible pump. Well development will consist of surging and purging until the groundwater no longer appears turbid and the measured total depth in the well is equivalent to the overall length of the well. Turbidity will be measured visually or with a field turbidity meter by a SoundEarth geologist during well development activities. It is expected that approximately eighteen 55-gallon drums of soil cuttings, decontamination water, and purge water will be generated during drilling and well development. Considering the uncertainty regarding the chemical composition of the soil and water, disposal costs have not been included in the attached estimate. An estimate to profile and coordinate the removal of the drums can be provided upon receipt of the laboratory results. Drilling, well installation, and well development activities are anticipated to take 4 days to complete. If requested by the client, SoundEarth will coordinate the removal of utility markings via pressure washing at the conclusion of our investigation activities for an additional charge. Task 3, Groundwater Sampling. Approximately 48 hours after well development is complete, two SoundEarth geologists will remobilize to the Property to survey the well elevations and collect two rounds of groundwater samples from each of the monitoring wells: one round after surveying well elevations and one round approximately three months after the first round of sampling. The groundwater samples will be collected according to EPA Low -Flow (Minimal Drawdown) Ground -Water Sampling Procedures (April 1996). The groundwater samples will be submitted to the laboratory for analysis of the following: SoundEarth Strategies, Ifnc.

Task 4, Data Review and Tabulation. Following completion of the soil and groundwater sampling activities and receipt of final laboratory analytical results, SoundEarth will tabulate and review the analytical data and produce a figure depicting sample locations and results. Considering the interim nature of the investigation, preparation of a full report is not included in this scope of work. Task 5, Project Management, Client Communications, and Meetings. This task includes labor costs associated with coordinating field schedule and staff resources for the project, as well as project coordination, contracting, and client/stakeholder communications and meetings. PROJECT SCHEDULE SoundEarth assumes that all necessary interior and exterior areas of the Property will be accessible during the subsurface investigation activities. Drilling, well installation, and groundwater sampling activities can be completed within 2 weeks of authorization to proceed, depending on driller availability and the duration of the permitting process. SoundEarth anticipates laboratory results will be available within 2 weeks of each phase of field work. SoundEarth shall proceed with such services in a diligent manner to completion or as otherwise directed by the client. SoundEarth will not be responsible for delays caused by factors beyond the consultant's control and which could not have been reasonably foreseen or prevented. PROJECT ESTIMATED COST The estimated cost for this scope of work is described in the attached Table 1. SoundEarth proposes to complete this work on a time and materials contractual basis. Our cost estimate will not be exceeded without prior authorization from the client. SoundEarth Strategies, Ifo ac.

The cost of these additional services is included in the overall project budget and staff is not asking for additional budget authority. BACKGROUND The City of Tukwila hired SoundEarth Strategies, Inc. to perform Environmental Site Assessment services (ESA) in connection with the Tukwila Public Safety Plan. ESA services involve two phases; Phase I is the research of potential contamination and Phase II is soils testing. The initial contract provided Phase I services related to the Justice Center (JC) and Fire Station 52 (FS52) sites. On December 7th, 2017, Amendment No. 1 added Phase I and II services to the Public Works (PW) site, Phase II for the Justice Center site and Phase I the Fire Station 54 (FS54) site, in the amount of $111,937. On March 26, 2018, Amendment No. 2 added Phase II services to Fire Station 52 and 54, as well as some additional services needed for soils testing on the Justice Center site, in the amount of $36,325. On May 11 th, 2018, Amendment No. 3 called for additional Due Diligence services, however they were able to be covered by previously approved contingency as well as reallocating funds previously allocated to soils testing work on Fire Station 54, which were no longer needed. Therefore, the contract amount did not increase. On December 26th, 2018, Amendment No. 4 changed the duration of the contract, extending it to December 31, 2019. On March 26, 2019, Amendment No. 5 added remedial excavation and field support activities during construction, in amount of $85,770. In November of 2019, Amendment No. 6 added additional remedial excavation, field support and tank removal activities, in the amount of $73,000, bringing the not -to -exceed amount to $322,032. ANALYSIS Amendment No. 7 is to add services to perform a supplemental subsurface investigation at the Justice Center Site to evaluate groundwater conditions in the vicinity of the observed soil impacts of the Property by installing nine (9) monitoring wells and conducting sampling of the wells.
