(AECOM) is pleased to present this proposal to the City of Oshkosh (City) to prepare a feasibility study for reconstruction of the Red Arrow Park Parking Lot. Project Background The park consists of two park shelters, one with bathroom facilities, a playground, and paved parking lot. Several baseball diamonds are located to the east of the parking lot. Historical records indicate that this area was a location of an unlicensed municipal solid waste disposal site. The specific construction type for this site is trench and furrow, which consisted of excavating a long narrow trench, stockpiling the excavated fill next to the trench, filling the trench with municipal solid waste, and then waste then was covered by a few feet of soil. Then the next trench was excavated and covered and so on. The excess fill was used to cover the waste that was piled in the “Garbage Hill” location which is located to the east of the baseball diamonds. There reportedly are five below-ground trenches approximately 70 to 90 feet wide, 10 feet deep, and up to 200 feet long or longer. This historical information is referenced in the book entitled “The History of Sanitation in Oshkosh” by Lanchow, and the engineering plan dated February 1956. Project Understanding We understand the City is considering reconstructing the parking lot and eventually tearing down the two wooden buildings/shelters. The restroom is expected to remain. It is anticipated that the Wisconsin Department of Natural Resources (WDNR) considers this an abandoned landfill site, and will likely require an exemption to permit construction on an abandoned landfill prior to reconstruction of the parking lot and remodeling the buildings on the site. This requirement post-dates the original construction of the park and site features. The City is requesting AECOM provide a feasibility study which includes WDNR coordination for permit requirements, a preliminary subsurface exploration, storm water management concepts, and opinion of probable construction cost for this project. The reason for this study to provide a basis for future planning for the site. Please note that this scope of work may trigger or lead to regulatory action in regards to Solid Waste Landfill Monitoring and construction on a historic landfill. Scope of Services Task 1: Project Management, Site Map, and WDNR Coordination The AECOM Project Manager (Paul Timm) will coordinate the project and provide a communication link between City and AECOM staff. Mr. Timm will also lead the discussions with the WDNR-assigned Project Manager.

We anticipate using the following information and data sources: • Book entitled “ A History of City of Oshkosh Sanitation Department” by Langkau • Abrams Aerial Survey Corp Sheet No. B-6, dated February 1965 • Current City of Oshkosh GIS utility information • Current LIDAR topographic survey information • The most current aerial photograph of the site available • Proposed Parking Lot Layout prepared by Steve Dittmer dated July 27, 2020 Once this informational site map is prepared, it will be used in discussions with WDNR to identify construction permit requirements. AECOM personnel will contact the appropriate WDNR staff in Solid Waste, and Storm Water groups and discuss the project. The intent is to introduce the potential project and verify regulatory requirements. This task will be completed prior to starting the other tasks. Deliverables AECOM will provide an electronic copy of the compiled site base map for City review. Once City comments are received and appropriate modifications are made to the site plan, the WDNR will be contacted. AECOM will provide an email summary of the discussions with the various WDNR staff. The summary emails will be copied to WDNR staff for concurrence. Task 2: Storm Water Management Plan Alternatives The parking lot is constructed over a historic landfill, and as such, the project is exempt from infiltration requirements. Therefore, storm water management will need to be designed to incorporate an impermeable barrier if constructed within the footprint of the historic landfill. Furthermore, depending on the location of the storm water management, the depth of storm water management may be limited depending on location due to the depth of waste. In review of historical documents developed as part of Task 1, AECOM will provide, at most, three initial concept drawings and perform a feasibility study for the use and location of different storm water management features such as permeable pavers, biofilters, and/or grass filter strips overlying the impermeable barrier. An engineer’s opinion of probable cost will also be prepared for the different options. A WinSLAMM analysis model will be used to calculate the size requirements. Based on past project experience with the City, AECOM assumes permeable pavers are preferred over permeable asphalt and concrete, and therefore, our cost analysis will not include the use of different types of permeable pavement. Upon completion of the feasibility analysis, AECOM will review with the City in order to decide final design direction. A decision regarding the final design direction will be necessary shortly after the aforementioned review. During final design, either HydroCAD, Storm and Sanitary Analysis, or XP-SWMM software will be utilized to size storm infrastructure. AECOM assumes storm water collected on-site will be discharged to public storm infrastructure in N. Westfield Street. AECOM will prepare a draft and final version of the storm water plan view showing the storm water management area, conveyance piping, and non-standard details for incorporation into the City’s plans for this project. AECOM will provide information in AutoCAD Civil 3D, version 2018 format as well as PDF. AECOM assumes the City will prepare other pertinent plans to develop the plan set. AECOM assumes the City will review the draft storm sewer information in their development of the grading plans and AECOM will be notified if cover issues arise which will be addressed in the final version of the drawing. Please note this task will be completed using the LIDAR survey information provided by the City. A detailed topographic survey will be required to confirm critical surface feature elevations before the final storm water management option is completed.

Once comments are received, and a final option is selected, AECOM will prepare one hard copy and electronic copy of the final documents. Task 3: Subsurface Investigation and Landfill Gas Monitoring AECOM proposes to define the extent of the municipal waste and monitor for landfill gases using hydraulic probes on the site. For budgeting purposes, AECOM assumes that the perimeter can be defined with the advancement of approximately 16 direct push technology (DPT) soil borings and converting six of them to 1-inch diameter gas monitoring points. The hydraulic probe locations will be placed along the approximate parking lot boundaries, inside of the parking area, and near the buildings. The gas monitoring points will be selected based on subsurface soils or waste observations. We anticipate at least one monitoring point to be located near each building. All excess soils will be stored in a sealed and labeled 55-gallon drum for storage until disposal is arranged. The soil borings will be advanced to the depth of the buried municipal waste (anticipated at 10-15 feet below ground surface [bgs]) to aid in calculating the approximate volume of municipal waste. Representative samples of the waste material will be collected and held for potential future laboratory analysis to analyze its composition for gas production analysis and potential landfill waste characterization. Documentation of the soil borings will be completed using the boring log format required by WDNR Form 4400-122 for each boring. AECOM will compile the data for analysis of the nature and extents of the buried municipal waste. Once the approximate horizontal and vertical limits of the waste have been defined, AECOM will identify appropriate locations for the installation of gas monitoring wells. AECOM expects that six gas wells will need to be installed to investigate the composition of the landfill gases being produced by the buried municipal waste. The gas wells will be constructed of 1-inch diameter PVC with appropriate sand pack and seal and protected with flush mount protectors. At each gas monitoring well, the initial percent of the LEL of methane (percent LEL methane), percent methane gas (percent methane), percent oxygen (percent O2), percent of carbon dioxide (percent CO2), and groundwater levels will be measured. The LEL is the minimum concentration of a particular combustible gas or vapor necessary to support its combustion in air. The LEL of methane gas is 5% methane by volume. Observations (such as ground condition, barometric pressure, and monitoring well conditions) will also be recorded. After initial readings are recorded, monitoring wells will be purged with a pump at a rate of two liters per minute. Continuous percent LEL methane will be measured as the well is purged. A final reading will be recorded when consecutive methane readings are within +10% LEL. Final measurements include percent LEL methane, percent methane gas, percent CO2 and percent O2. The length of time required to achieve the final reading is typically unique to each well. We have included a minimum of four quarters of monitoring in an effort to develop a trend in potential landfill gases. AECOM will prepare a preliminary subsurface assessment report to document the data obtained from the above scope of services. The report will include a discussion of field investigation methodology and physical characteristics of the site, discussion of results with respect to regulatory standards, and recommendations for additional investigation, if necessary. This report will be taken into consideration for preparation of the Opinion of Probable cost task.
