Discussion followed on the projects scheduled for 2025 which include construction of park improvements at 430 S.

City of Naperville Page 2 Printed on 8/7/2024 Riverwalk Planning, Design and Meeting Minutes July 2, 2024 Construction Committee Discussion followed on the CIP spreadsheet, which lists total project costs. Per Kennedy’s request, Novack will include a footnote indicating that costs shown do not include outside funding. It was also noted that discussions should be held with the major donors regarding any changes in the timing of the projects. Novack will update the document to show $200,000 dedicated in 2025 for the South Extension project groundbreaking. Discussion followed on the funding arrangements and if grants were to go to the Riverwalk 2031 Fund or directly to the City of Naperville. Erickson suggested moving the Grand Pavilion project back, with Kennedy agreeing that the $150,000 scheduled in 2027 could be moved to 2028. Dusak noted the importance of capturing the West Parking Lot BMP with the Grand Pavilion improvements. The group discussed the soil condition and testing that needs to be done to allow for permeable pavers. Discussion followed on if any grant dollars would be available for this project under green infrastructure with Dusak noting that it will be taken into consideration. Novack discussed the condition of the retaining wall near Aurora Avenue that will need to be addressed in the future. It was suggested that it should be included in the five-year plan. Picco will review the Asset Management Plan to determine if any additional items need to be included with the Capital Improvement project submittal. 2. Riverwalk Standard Paving Bricks - Bill Novack Discuss and provide feedback regarding the next Naperville Riverwalk standard paving brick Novack discussed the standard Stockholm paver that was used for the Riverwalk when it was initially constructed. The Stockholm paver was manufactured by Paveloc, which was bought out by Unilock. As Unilock no longer supplied this mold, a decision is needed on a new standard brick for the Naperville Riverwalk. Novack reviewed the examples included in the agenda packet of the standard Stockholm (wavy) pavers and also the Il Campo pavers that are used downtown, in the Youth Plaza on the Riverwalk, and at the entrance to North Central College (NCC) near Fredenhagen Park. Tim Ball advised that he recently received information from Unilock stating they have repaired the Stockholm mold which has been optimized for Endura color technology, and that they recommend using the premier finish to match existing and later phases of the Naperville Riverwalk. They also noted that the Il Campo mold is available. They would need to run in batches of 3,000 sq. ft. per color and paver to maximize cost and production. City of Naperville Page 3 Printed on 8/7/2024 Riverwalk Planning, Design and Meeting Minutes July 2, 2024 Construction Committee Novack noted that many Riverwalk bricks have been salvaged from other areas and utilized with some of the smaller Riverwalk projects. Ball noted that he recently met with another vendor and is awaiting additional information. Discussion followed on the importance of the exact specifications of the existing bricks, with Penick and Picco noting the importance of smooth pathways and safety. Picco discussed the various shades of red of the existing pavers due to patching, etc. The possibility of bidding an alternative to include a different paver if the Stockholm style could not be replicated was suggested. Erickson liked keeping the same shape of the Stockholm on the pathways, with the style used in the Youth Plaza for use in other plazas. Peterson noted that this was in line with the plans for the 430 S. Washington Street project. Novack discussed the herringbone pattern that is used at NCC and noted the color specifications would have to be agreed upon. The consensus and recommendation from the PDC Committee was to maintain the existing Stockholm style paver in the Riverwalk pathways with an alternate for another exact sized 4” x 8” paver consistent with the Il Campo style used at NCC. Pavers in plazas would be consistent with the existing style and layout currently in the Youth Plaza on the Riverwalk. This will be included on next week’s Riverwalk Commission agenda. 3. Riverwalk Millennium Labyrinth - Bill Novack Discuss and decide if the Riverwalk Commission should pursue cleaning, staining and sealing of the labyrinth at the Riverwalk Millennium Labyrinth Attachments: Millennium Labyrinth History Novack provided background information on the labyrinth that was installed near the Riverwalk Amphitheater in 1999. The contrasting bricks have faded and would need to be stained and sealed to restore the labyrinth. This request came from a resident and the examples of possible restoration were included in the agenda packet. Discussion followed on previous requests to restore the labyrinth and the possibility of using volunteers to complete the project. Novack noted that PA022 funds could be used but the project would have to be bid out. Picco noted the importance of maintenance plans for all existing Riverwalk assets for planning and budgeting purposes. She inquired if the staining and sealing would be affected by power washing as they have to remove silt after flooding events. The consensus from the PDC Committee was to restore the labyrinth. Novack will get more information on the life-cycle costs and staining. It was noted that Park District staff could perform the power washing and sealing. City of Naperville Page 4 Printed on 8/7/2024 Riverwalk Planning, Design and Meeting Minutes July 2, 2024 Construction Committee Novack provided an update on a recent meeting with NCC regarding the 430 S. Washington Street project. It was discussed that the traffic signal mast arm on the northeast corner of Aurora Avenue and Washington Street may obstruct their gateway. It is scheduled to be poured in November or December so the area will be surveyed afterwards and another meeting will be set up with NCC. Novack will bring the final plans back to the Riverwalk Commission after this meeting. F. MEETING SCHEDULE: Riverwalk Commission, July 10, 2024, 7:30 a.m. Municipal Center NEU, 400 S.
