Terracon Project No.: 11167327
Dear Mr. Evans:
Terracon Consultants, Inc. (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

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.

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

Terracon Project No.: 11167327
Dear Mr. Evans:
Terracon Consultants, Inc. (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. 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.

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. 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

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.

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.

Attn: Mr. Tim Evans
Director of Parks and Recreation
Re: Environmental Soil Removal, Backfill and Concrete Installation
Riverfront Park
East Hydraulic St
Yorkville, Illinois
Terracon Proposal No.: P11177077
Dear Mr. Evans:
Terracon Consultants, Inc. (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.

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

indicated above. Work on Sundays and Holidays will be invoiced at 2.0 times the hourly rate.
The above rates are portal-to-portal from our Naperville, Illinois office.
2. If requested services are cancelled upon arrival to project site,a four(4)hour minimum charge
and appropriate trip charge per visit will be applied.
3. Project Manager time will be billed at a minimum of/2-hour per technician per day.
The rough total cost estimate and assumptions are included in the table above and attached
spreadsheet.
It should be noted that we have prepared the cost estimate based on our past experience with projects
of similar size and requested services. If additional services are requested that are not outlined in
scope of services outlined above and in attached cost estimate, we will be glad to provide the
requested services at the applicable unit rates.
Terracon's fees would be determined by the actual amount of technical time expended for this project
and the amount of laboratory testing performed. The actual cost of our services will depend on the
construction schedule, weather, site conditions and contractor performance. Terracon pledges to
work carefully with the City to perform the required services as efficiently and economically as
possible.
We anticipate that more than one Terracon invoice may be submitted as various tasks are completed;
however, not more frequently than on a monthly basis. If additional work is required outside the scope
of this proposal, you will be contacted and upon request, proposed costs for additional work will be
provided. Client authorization will be obtained prior to commencement of additional work outside the
scope of this proposal.
This proposal and cost estimate were prepared based on the following assumptions:
The City will provide to Terracon, prior to mobilization, legal right of entry to the site
(and other areas if required) to conduct the scope of services.
The City will notify Terracon, prior to mobilization, of any restrictions, special site
access requirements, or known potentially hazardous conditions at the site (e.g.,
hazardous materials or processes, specialized protective equipment requirements,
unsound structural conditions, etc.).
Utilities on private land that are not located by public companies will be located by the
City. Terracon will not be responsible for underground utilities damages if utilities are
not marked correctly. Private utility locate is not included in this proposal.
Work can be performed during normal business hours (Monday through Friday, 8:00
am to 5:00 pm).
Traffic control services are not required.
Level D personal protective equipment will be adequate for site work.
R Excavated soil will be properly disposed of as non-hazardous and waste
characterization sampling is not required.
■ Excavation confirmatory samples will not be collected at the City's request.

The client will provide a secured site prior to beginning the remediation.
The assumed soil volume and number of days on-site are summarized in the Proposed
Budget Table above. The actuals may vary pending on the site condition.
If any of these assumptions or conditions are not accurate or change during the project, the stated
fee is subject to change. Please contact us immediately if you are aware of any inaccuracies in these
assumptions and conditions, so we may revise the proposal or fee.
3.2 Schedule
Terracon is prepared to initiate this work upon receipt of written notification to proceed. The field
activities will be coordinated with the City. The start date will be dependent on utility clearance and
excavation contractor availability. It is anticipated that the field activities will be completed in 12
working days. However, working days may not be consecutive based on weather. The standard
environmental analytical turnaround time for clean soil is 5-business days. A draft report will be
available two weeks after receipt of all the soil disposal documentation from the landfill.
3.3 Additional Limitations
Terracon's services will be performed in a manner consistent with generally accepted practices of the
professional undertaken in similar studies in the same geographic area during the same period.
Terracon makes no warranties, expressed or implied, regarding its services, 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 will be performed in accordance with the scope of work agreed with you, our client, as set
forth in this proposal and are not intended to be in strict conformance with ASTM International
standard practice E1903-11.
Findings, conclusions, and recommendations resulting from these services will be based upon
information derived from 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, and we cannot represent that
the site contains no hazardous substances, toxic substances, petroleum products, or other latent
conditions beyond those identified during the proposed activities. Subsurface conditions may vary
from those encountered at specific borings or wells 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.
