(Terracon) is pleased to submit this Environmental Soil Evaluation Report for the above referenced site. This evaluation was performed in general accordance with Terracon proposal No. P11167327, dated September 23, 2016, and your authorization to proceed on September 26, 2016. The purpose of the evaluation was characterize previously excavated soil from park construction for proper disposal and to conduct a limited evaluation of impact within the eastern portion of the park. The evaluation included collection of soil samples for field screening and laboratory analysis and comparison of the analytical results to IEPA Tier 1 soil remediation objectives outlined in 35 IAC Part 742 (TACO). 1.0 PROJECT INFORMATION The project site consists of a proposed playground in Riverfront Park generally located at 131 East Hydraulic Ave in Yorkville, Illinois (site). Terracon understands that construction of the proposed playground includes installation of equipment post foundations and surficial grading. Terracon understands that up to approximately 1,000 cubic yards of soil will be generated during site work. Personnel from the City reported that during excavation for post foundations a petroleum odor was noted in the eastern portion of the proposed playground. The City has stockpiled the impacted soils encountered temporarily on-site. Terracon conducted a limited evaluation of site soils at sample locations directed by the City. The results are provided in this report. Personnel from the United City of Yorkville's park district utilized Terracon Consultants, Inc. 135 Ambassador Drive Naperville, IL 60540 P (630) 717-4263 F (630) 357-9489 www.terracon.com Environmental Soil Evaluation Services Report Irerracon Riverfront Park Yorkville, Illinois October 20, 2016 Terracon Project No.: 11167327 a solid stem auger mounted on a skid steer to advance four borings to 3 feet. The site soil generally consisted of brown sand and gravel fill, trace clayey sand, black stained sands and petroleum-like odors to approximately 3 feet below existing grade, the maximum depth of exploration. 1.1 Standard of Care Terracon's services were performed in a manner consistent with generally accepted practices of the profession undertaken in similar studies in the same geographical area during the same time. Terracon makes no warranties, either express or implied, regarding the findings, conclusions, or recommendations. Please note that Terracon does not warrant the work of laboratories, regulatory agencies, or other third parties supplying information used in the preparation of the report. These services were performed in accordance with the scope of work agreed with you, our client, as reflected in our proposal. 1.2 Additional Scope Limitations Findings, conclusions, and recommendations resulting from these services are based upon information derived from the on-site activities and other services performed under this scope of work; such information is subject to change over time. Certain indicators of the presence of hazardous substances, petroleum products, or other constituents may have been latent, inaccessible, unobservable, non-detectable, or not present during these services. We cannot represent that the site contains no hazardous substances, toxic materials, petroleum products, or other latent conditions beyond those identified during this evaluation. If these conditions arise during the course of this project, you should halt excavation activities and the suspect soil/fill should be re-evaluated to determine the appropriate soil/fill disposal options. Subsurface conditions may vary from those encountered at specific borings or during other surveys, tests, assessments, investigations, or exploratory services. The data, interpretations, findings, and our recommendations are based solely upon data obtained at the time and within the scope of these services. 1.3 Reliance This report has been prepared for the exclusive use of the United City of Yorkville and any authorization for use or reliance by any other party is prohibited without the express written authorization of the United City of Yorkville and Terracon.

Responsive■ Resourceful ■ Reliable 2 Environmental Soil Evaluation Services Report Irerracon Riverfront Park Yorkville, Illinois October 20, 2016 Terracon Project No.: 11167327 2.0 SAMPLE COLLECTION On September 27, 2016, a Terracon field representative mobilized to the site to collect soil samples from the project area. Soil samples were observed for visual indications of contamination and screened with a photoionization detector (PID) to aid in identification of the relative presence/absence of volatile organic vapors (VOVs). Field PID and screening indicated readings above ambient background in each of the four borings at each 1 foot interval. PID readings in A-1 to A-4 ranged from approximately 2.1 ppm to 1,312 ppm. Discrete soil samples were selected from the auger locations (WC-1, A-1, A-2, A-3 and A-4) in the eastern portion of the proposed playground for laboratory analysis as representative of excavated materials generated from construction activities. The four soil samples were submitted to First Environmental Laboratories of Naperville, Illinois (a National Environmental Laboratory Accreditation Program-accredited laboratory) under standard chain-of-custody protocols, in laboratory provided glassware. The samples were analyzed for the volatile organic compounds (VOCs), polynuclear aromatic hydrocarbons (PNAs), Resource Conservation and Recovery Act (RCRA) metals and pH. One additional "composite" sample of soil from the noted location was also collected and submitted for waste characterization sampling. This sample was submitted to the laboratory and run for pH, Flashpoint, Paint Filter, toxicity characteristic leaching procedure (TCLP) Metals (8), TCLP VOCs, TCLP semi-volatile organic compounds (SVOCs), and polychlorinated biphenyls (PCBs) noted by the City's selected disposal company. 3.0 LABORATORY AND ANALYTICAL RESULTS Laboratory analytical results were compared to the Tiered Approach to Corrective Action Objectives (TACO)Tier 1 Soil Remediation Objectives (SROs). Analytical results are tabulated in comparison to the SROs in Tables 1 through 4 attached to this report. The laboratory analytical report is also provided as an attachment to this report. As outlined in Tables 1 through 4, analytical results indicated exceedances of the Tier 1 ROs for the Class I Soil Component of the Groundwater Ingestion Route RO, construction worker inhalation, residential ingestion, and residential inhalation exposure pathways. A summary of the constituents that exceeded at least one RO is provided below: Volatile Organic Compounds — Benzene, bromomethane, carbon tetrachloride, chloromethane, dibromochloromethane, 1,2-dichloroethane, 1,1-dichloroethene, 1,2- dichloropropane, 1,3-dichloropropene (cis+trans), 2-hexanone, methylene chloride, tetrachloroethene, trichloroethene, 1,1,2-trichloroethane and vinyl chloride exceeded Responsive■ Resourceful ■ Reliable 3 Environmental Soil Evaluation Services Report 1rerracon Riverfront Park u Yorkville, Illinois October 20, 2016 r., Terracon Project No.: 11167327 their Tier 1 ROs in samples A-1 and A-4. Ethylbenzene and total xylenes also exceeded their Tier 1 ROs in sample A-4. Polynuclear Aromatic Hydrocarbons — Naphthalene exceeded their Tier 1 ROs in samples A-1 and A-4. RCRA Metals— Mercury exceeded a Tier 1 RO in sample A-3. Chromium exceeded a Tier 1 RO in sample A-4. 4.0 CONCLUSIONS Terracon conducted an environmental evaluation of soil proposed to be removed from the project area.

This evaluation was performed in general accordance with Terracon proposal No. P11167415, dated December 2, 2016, and your authorization to proceed on January 12, 2016. The purpose of the evaluation was to further characterize soil in three areas surrounding the Riverfront Park at locations determined by the United City of Yorkville (City). The evaluation included collection of soil samples for field screening and laboratory analysis and comparison of the analytical results to IEPA Tier 1 soil remediation objectives outlined in 35 IAC Part 742 (TACO). 1.0 PROJECT INFORMATION The project site consists of three testing areas along the Riverfront Park, generally located at 131 East Hydraulic Ave in Yorkville, Illinois (site). Terracon previously conducted an Environmental Soil Evaluation in a proposed playground area of the park and presented results in a Soil Evaluation Report dated October 20, 2016 (Terracon No. 11167327). The Soil Evaluation Report indicated exceedances of the Illinois Environmental Protection Agency (TEPA) established Tier 1 remediation objectives (ROs) in two samples (A-1 and A-4) collected on the east end of the proposed playground.

Terracon makes no warranties, either express or implied, regarding the findings, conclusions, or recommendations. Please note that Terracon does not warrant the work of laboratories, regulatory agencies, or other third parties supplying information used in the preparation of the report. These services were performed in accordance with the scope of work agreed with you, our client, as reflected in our proposal. 1.2 Additional Scope Limitations Findings, conclusions, and recommendations resulting from these services are based upon information derived from the on-site activities and other services performed under this scope of work; such information is subject to change over time. Certain indicators of the presence of hazardous substances, petroleum products, or other constituents may have been latent, inaccessible, unobservable, non-detectable, or not present during these services. We cannot represent that the site contains no hazardous substances, toxic materials, petroleum products, or other latent conditions beyond those identified during this evaluation. If these conditions arise during the course of this project, you should halt excavation activities and the suspect soil/fill should be re-evaluated to determine the appropriate soil/fill disposal options. Subsurface conditions may vary from those encountered at specific borings or during other surveys, tests, assessments, investigations, or exploratory services. The data, interpretations, findings, and our recommendations are based solely upon data obtained at the time and within the scope of these services. 1.3 Reliance This report has been prepared for the exclusive use of the United City of Yorkville and any authorization for use or reliance by any other party is prohibited without the express written authorization of the United City of Yorkville and Terracon. Reliance by authorized parties will be subject to the terms, conditions and limitations stated in the proposal, report, and Terracon's agreement for services. The limitation of liability defined in the terms and conditions is the aggregate limit of Terracon's liability to the United City of Yorkville and all relying parties unless otherwise agreed in writing. 2.0 SAMPLE COLLECTION On January 18, 2017, a Terracon field representative mobilized to the site to collect soil samples from the project area. Personnel from the United City of Yorkville (City) utilized a solid stem auger mounted on a skid steer to advance six borings to 3 feet. Boring locations were determined by City personnel. Site soil generally consisted of brown sand and gravel fill underlain by silty clay Responsive■ Resourceful ■ Reliable 2 Environmental Soil Evaluation Services Report Irerracon Riverfront Park Yorkville, Illinois February 1, 2017 Terracon Project No.: 11167327 fill to approximately 3 feet below existing grade, the maximum depth of exploration. Soil boring locations are shown on Exhibit 1 attached to this report. At the direction of the City, soil samples were collected from three separate testing areas within the proposed park. Testing Area 1 included was approximately 400 feet west of the park (A-5 and A-6); Testing Area 2 was approximately 100 feet northeast of the proposed playground area (A- 9 and A-10); and Testing Area 3 was approximately 100 feet east of the proposed playground area (A-7 and A-8). A seventh samples was anticipated for Testing Area 1, but the City requested two samples for this Area during field sampling. Soil samples were observed for visual indications of contamination and screened with a photoionization detector (PID) from the surface to 3 feet below ground surface (bgs) to aid in identification of the relative presence/absence of volatile organic vapors(VOVs). A faint petroleum odor was identified in soil from boring A-8. Elevated PID readings in boring A-8 were detected from approximately 8 ppm to 12 ppm. The six soil samples were submitted to First Environmental Laboratories of Naperville, Illinois (a National Environmental Laboratory Accreditation Program-accredited laboratory) under standard chain-of-custody protocols, in laboratory provided glassware. The samples were analyzed for the volatile organic compounds (VOCs), polynuclear aromatic hydrocarbons (PNAs), Resource Conservation and Recovery Act (RCRA) metals, and pH. 3.0 LABORATORY AND ANALYTICAL RESULTS Laboratory analytical results were compared to the Tiered Approach to Corrective Action Objectives (TACO)Tier 1 Soil Remediation Objectives (SROs). Analytical results are tabulated in comparison to the SROs in Tables 1 through 4 attached to this report. The laboratory analytical report is also provided as an attachment to this report. As outlined in Tables 1 through 4, analytical results indicated exceedances of the Tier 1 SROs for the Soil Component of the Class I Groundwater Ingestion, construction worker inhalation, and residential ingestion exposure pathways. A summary of the constituents that exceeded at least one SRO is provided below: Volatile Organic Compounds —were not identified above laboratory reporting limits. Polynuclear Aromatic Hydrocarbons — Benzo(a)anthracene, benzo(a)pyrene, benzo(b)fluoranthene, dibenzo(a,h)anthracene, and indeno(1,2,3-c,d)pyrene exceeded the respective Tier 1 SROs for residential ingestion in sample A-8. The benzoenzo(a)anthracene concentration also exceeded the soil component to groundwater SRO for Class I groundwater in sample A-8. Responsive■ Resourceful ■ Reliable 3 Environmental Soil Evaluation Services Report Irerra-con Riverfront Park Yorkville, Illinois February 1, 2017 Torraco^ Project No.: 411167327 - RCRA Metals -Arsenic exceeded the Tier 1 SRO for residential ingestion in sample A-8; Mercury exceeded the Tier 1 SRO for construction worker inhalation in samples A-5, A-6, A-7, and A-9. Arsenic and Lead exceeded their pH-specific SROs for soil component to Class I groundwater in sample A-9. Cadmium, mercury and selenium had samples exceeding background concentrations with no pH-specific SRO available for comparison based on pH. This applied to samples A-6 and A8 for cadmium, A-6 for mercury, and sample A-8 for selenium. ate CONCLUSIONS Terracon conducted an environmental evaluation of soil proposed to be removed from the project area in six sample locations provided by the City. Based on the analytical results, exceedances of the Tier 1 SROs for the soil component of the groundwater ingestion (Class 1), construction worker inhalation, and residential ingestion pathways were identified.

(Terracon) appreciates the opportunity to submit this proposal to the United City of Yorkville (City) to conduct environmental services at the above-referenced site. The proposal was prepared in accordance with our site visit on February 17, 2017 and the layout drawing provided by the City on February 21, 2017. The following sections provide an outline of the project and Terracon's scope of services, compensation, and schedule. If we have misunderstood an aspect of the work, please let us know as soon as possible so we can evaluate our scope and make necessary adjustments. 1.0 PROJECT INFORMATION The project site consists of the proposed Bicentennial Riverfront Park generally located at Hydraulic Avenue and Mill Street in Yorkville, Illinois (site). Terracon previously conducted a Limited Environmental Soil Evaluation in the proposed playground and at specific areas around the playground as directed by the City. Results of the evaluation were presented in two Environmental Soil Evaluation Reports dated October 20, 2016 and February 1, 2017 (Reports). The Reports indicated exceedances of the Illinois Environmental Protection Agency (TEPA) Tier 1 remediation objectives (ROs) in five soil samples throughout the site. Based on the identified impact at the site, the City has requested that limited soil removal be conducted and concrete be installed in the proposed park area as directed by the City. 2.0 SCOPE OF SERVICES 2.1 Health and Safety Plan Terracon Consultants, Inc. 135 Ambassador Drive Naperville, Illinois 60540 P [630] 717 4263 F [630] 357 9489 terracon.com Proposal for Environmental Services Irerracon Riverfront Park■Yorkville, IL March 17, 2017 ■Terracon Proposal No. P11177077 Terracon is committed to the safety of all its employees. As such, and in accordance with our Incident and Injury Free® safety goals, Terracon will update the existing safety plan for use by our personnel during field services. Prior to commencement of on-site activities, Terracon will hold a brief health and safety meeting to review health and safety needs for this specific project. At this time, we anticipate performing fieldwork in a United States Environmental Protection Agency(USEPA)Level D work uniform consisting of hard hats,safety glasses, protective gloves,and steel-toed boots. It may become necessary to upgrade this level of protection, at additional cost, during sampling activities in the event that we encounter petroleum or chemical constituents in soils or groundwater that present an increased risk for personal exposure. 2.2 Utility Clearance No later than 48 hours prior to intrusive activities, Terracon's excavation subcontractor will contact the local one-call public utility locating service (e.g., JULIE) to arrange for public underground utility locates atthe site. Please note that the public utility locator only locates public utilities.The City and/or site representatives shall provide information on the presence and location of private utilities, operational piping, and subgrade features. Terracon is not responsible for damages related to improperly marked utilities or to private utilities for which information is not provided. 2.3 Clean Fill Sampling Prior to sampling, an environmental database report for the prospective fill site will be obtained and reviewed. If evidence of environmental impact is not identified for the fill source site, Terracon personnel will mobilize to the fill source and obtain two representative samples for laboratory analysis representing up to 2,000 cubic yards of import soil. Samples will be visually classified in the field and screened with a photoionization detector(PID). Samples will be selected for laboratory testing based on elevated PID readings or visual or olfactory evidence of potential contamination. Analytical samples will be submitted to Terracon's subcontract laboratory for analysis of Target Compound List parameters outlined in Title 35 of the Illinois Administrative Code Part 740 (35 IAC 740)Appendix A and total petroleum hydrocarbons (TPHs) on standard 7-business day turnaround. 2.4 Limited Soil Removal, Concrete Installation, and Clean Backfill Terracon and an excavation subcontractor will mobilize to the site to conduct limited soil removal at the site. A diagram showing the excavation area designated by the City is attached to this proposal. Based on the attached drawing the anticipated excavation is approximately 13,000 square feet in area.Within the designated area soil will be removed to a depth of three (3)feet below grade, directly loaded into trucks, and transported to a permitted subtitle D landfill. The waste profile previously approved by Advanced Disposal's Orchard Hills landfill will be utilized for the project. Further waste profile testing is not included. Upon reaching the excavation extent per City's instruction, soil at the base of the excavation will be evaluated and compacted, as necessary, to provide stable soil subgrade for the aggregate base. Responsive ■ Resourceful ■ Reliable 2 Proposal for Environmental Services Irerracon Riverfront Park ■Yorkville, IL March 17, 2017 ■Terracon Proposal No. P11177077 Approximately 4-inches of crushed stone aggregate base will be placed at the base of the excavation and compacted. Based on the surficial land use as a park (i.e. no vehicle or heavy load traffic), the base aggregate will be compacted to 90% of the material's standard proctor dry density. Within the playground area, the top of the aggregate surface will be sloped at approximately 1-2% to the north to allow for drainage of storm water away from the playground surface. Terracon field staff will conduct a limited survey using general survey equipment to verify slope of the aggregate or concrete surface. Professional survey is not included in this proposal. Per client's instruction, concrete will be poured over top of the 4-inch aggregate base such that a 4- inch concrete slab is present across the excavation area, except as noted below for the playground decorative wall. During the pour, Terracon will perform slump and air content tests, and cast compressive strength test cylinders. A total of 6 cylinders will be cast for every 50 cubic yards of concrete placed. The concrete will be allowed to cure until 75% of the design strength is met prior to clean soil imported and backfilling operations commence. Subsequent to the concrete curing, clean soil from the approved clean soil source will be imported to the site and placed over the concrete. Soil will be placed in approximate 10 to 12 inch thick loose lifts and compacted to 90%of the material's standard proctor dry density. At the City's request, efforts will be taken during excavation to maintain the integrity of the decorative wall surrounding the proposed playground area. We understand that the wall is built on top of an approximate 10-inch layer of crushed stone aggregate. The level of compaction applied to the aggregate is not known. During excavation in this area approximately 1-2 feet of soil will be left in place adjacent to the wall, with an approximate 1:1 slope from the wall to the three foot bottom of the excavation. A barrier between the base of the excavation and the wall will be constructed of plastic sheeting or similar flexible material. It should be noted that it may not be possible to preserve the wall due to circumstances beyond Terracon's control. As discussed, caution will be exercised to preserve the wall; however, should the wall be damaged during or post construction, Terracon, or our subcontractors, will not be held responsible for repairs or replacement of the wall. The wall repair cost is not included in this proposal. 2.5 Report Preparation At the completion of the limited soil removal and backfilling a brief report will be prepared documenting site work. An electronic version of the written report will be provided and include the following. Documentation of field activities Site plan showing pertinent site features and sample locations ■ Clean fill analytical laboratory results ■ Compaction and concrete testing results Disposal records for excavated soil Responsive ■ Resourceful ■ Reliable 3 Proposal for Environmental Services Irerracon Riverfront Park Yorkville, IL March 17, 2017 - Terracon Proposal No. P11177077 This scope of services has been directed by the City and is not intended to identify, delineate, or remediate all potential impact at the site.
