SMOLLEN Village Clerk June 2, 2014 Village of Lemont 418 Main Street Lemont, IL 60439 Attention: Mr.George J. Schafer Village Administrator Subject: Proposal for Professional Engineering Services for Improvements to the Illinois and Michigan Canal Christopher B. Burke Engineering, Ltd. (CBBEL) is pleased to present this proposal for engineering services related to a project to increase the depth and quality of water in the Illinois and Michigan Canal (Canal) in the downtown area of the Village of Lemont (Village). Included in this proposal is our Understanding of the Assignment,Scope of Services,and Fee Estimate. UNDERSTANDING OF ASSIGNMENT We understand that the Village would like to construct improvements to the Canal in its downtown area to increase the depth of water and improve the existing water quality. The depth of water in the Canal is currently very shallow and tends to be stagnant in summer months. We understand the Village would like to raise the water level of the Canal in the downtown area by constructing concrete walls across the Canal in two locations, one near Stephen Street and one west of downtown. The concrete walls would extend +/- 3 feet above the current water level. The impoundment area would be supplied by runoff from two tributaries that feed into the Canal, including the Castle Bowl Tributary and the l&M Canal Tributary A, which enters near the Village's Fire Station No. 1. If necessary, a well or a municipal water supply may be required for supplying makeup water during summer months when evaporation is high. Design of the makeup water system and/or recirculating system is not included in this contract. During a flood event, the proposed concrete walls would be submerged and would not significantly affect the flow of water. We understand that the Village has previously investigated aeration and diffuser requirements to improve water quality, therefore these systems will not be investigated as part of this proposal. However, if desired, we will develop engineering for a "cascade-type" recirculation system, which would include pumping water from the impoundment area into a cascading rock structure, which would create aeration and improve water quality as well as aesthetics. SCOPE OF SERVICES We propose the following scope of services to successfully complete this project: Task 1 — Initial Permit Coordination: There are several agencies from which permits or approvals will be required, including the Illinois Department of Natural Resources, US Army Corps of Engineers, Illinois Historic Preservation Agency, and l&M Canal Corridor Association. It is unknown at this time how the proposal would be viewed by each agency. Our assumption is that since the project is intended to simply improve aesthetics and water quality, providing a better experience for users of the Canal corridor, the permitting agencies will be agreeable. We have also assumed that extensive hydraulic analyses will not be required. However, we recommend having initial meetings with these agencies before beginning engineering to verify that the project is feasible and to fully understand the permitting expectations. The time requirement for this task is unknown and therefore we have proposed this task to be billed on a Time and Materials basis. If the project scope becomes unpermittable we will stop our design effort and suggest terminating the project. Task 2 — Topographic Survey: Our survey crews will complete a limited topographic survey of the two areas proposed for the concrete walls (+/- 50 linear feet of channel bank for each side at each wall location). We will survey the water level, Canal walls, and bank areas adjacent to the proposed walls, and will use information provided by the Village for the Canal dredging project for the below-water portion of the project. Task 3 — Structural Design and Plan Preparation: CBBEL will complete the structural design of the two impoundment dams for the Canal. The dams will be approximately 12 ft tall and 60 ft wide. The dams will be constructed with cast in place concrete, and both faces of the dam will have formliner to create an aesthetically pleasing look. The Village will choose the pattern of the formliner. It is our understanding that there is no significant flow in the canal, and the dams will be design for only hydrostatic pressure. There may be one or two small valves in the concrete walls for discharging and controlling the water level behind the dams. The design plans will have plan and elevation views, typical sections and any required special details. The structural plans will be accompanied by a cover sheet, erosion control plans and a summary of quantities plan. CBBEL will follow IDOT Standard Specifications and provide any special provisions required for the project. The Shop Drawing review is not included in this task. Task 4 — Evaluation of Makeup Water Requirements: It is expected that evaporation during summer months will remove water from the impoundment area. It is unknown whether evaporation will be more or less than the inflow from the two Canal tributaries. We will complete evaporation calculations, and consider the results of the Packer Testing in Task 3, to determine the need for a source of makeup water. Makeup water could be generated by drilling a shallow well, or through a municipal water supply. We will evaluate the costs of either JJJ N:\PROPOSALS\ADMIN\2014\Lemont_Illinois and Michigan Canal_052814.docx approach and provide appropriate recommendations. Design of a makeup water system is not included in this task. Task 5 — U.S. Army Corps of Engineers Permitting: We will complete a field investigation and wetland/waters delineation in the two project areas to identify any wetland areas and Waters of the U.S locations. Our findings will be summarized in a letter report, and if necessary, a Jurisdictional Determination request will be made to the U.S. Army Corps of Engineers. We will also submit Threatened and Endangered Species consultation requests with the Illinois Department of Natural Resources and the U.S. Fish and Wildlife Services(USFWS). In Task 1 (Initial Permit Coordination), we will determine the requirements of the Corps permit submittal. The required permit submittal documents will be prepared under this task. We have assumed the project will be permitted under the Regional Permit program and will not require an Individual Permit. If an Individual Permit is required, it will be handled under a separate contract. Task 6— IDNR-OWR Permitting: Permits will be required from the Illinois Department of Natural Resources — Office of Water Resources (IDNR-OWR) for construction in a floodway (Part 3700 Rules) and for Regulation of Public Waters. We have assumed that the project will not require significant permitting efforts based on the following assumptions: • IDNR will not be consider the project as reducing the navigability of the Canal • A major hydraulic analysis will not be required to demonstrate that the flood carrying capacity of the Canal will be unaffected by the project We have assumed that in Task 1 (Initial Permit Coordination) will verify these assumptions. Under this task, a simplified hydraulic analysis will be completed to provide IDNR-OWR with the required backup documentation of our assumptions. FEE ESTIMATE TASK DESCRIPTION FEE 1 Initial Permit Coordination T&M 2 Topographic Survey $ 3,800 3 Structural Design and Plan Preparation $ 20,500 4 Evaluation of Makeup Water Requirements $ 4,000 5 U.S.Army Corps of Engineers Permitting $ 5,000 6 IDNR-OWR Permitting $ 4,500 TOTAL $ 37,800 JJJ N:\PROPOSALS\ADMIN\2014\Lemont_Illinois and Michigan Canal_052814.docx Additional Services for Consideration: We have prepared the previous scope of services to minimize the cost to design the walls, establish a reliable estimated construction cost, and obtain key permits. Additional tasks may be required either at the Village's discretion, or as a permitting requirement, prior to construction. The following tasks are provided for your consideration. We would be happy to discuss these tasks further or provide a supplemental proposal at a later date: Task Estimated Cost Range • Geotechnical Analysis (if desired) $10,000-$18,000 • Recirculation/Aeration System Design (if desired) $10,000-$14,000 Note that we assume this project can be permitted under the Army Corps' Regional Permit program, and an individual permit will not be required. This assumption will be verified during the initial meetings with the permit agencies. We have also assumed that the project will be allowed under the IDNR's Regulations for Public Waters, which are intended to maintain navigability of public waterways; in our opinion, the Canal is not navigable in this area in its current condition. We have not included any cost in our proposal for a geotechnical analysis. Our structural analysis will be based on assumed bearing strength of bedrock typical of the area. We have also assumed that permeability of the bedrock will be low and will not significantly contribute to exfiltration of water out of the impoundment area. Minor exfiltration can be managed by introducing additional makeup water. If preferred by the Village, these assumptions could be verified before the project is constructed by completing soil and rock borings, and completing hydraulic testing of the rock. Finally, the recirculation system would include design and layout of a pump station and forcemain to pump water out of the impoundment area and over one or more rock cascades. The specific locations of these water features would need to be determined by the Village before they could be designed.
