An amended agenda was published as soon as possible, resent to those on the notice list and notice was posted at the Lowe Park location listed on the original agenda. Public Input None. Minutes Moved by Schoenhofer, seconded by Fay, to approve the minutes from April 13, 2026. Approved unanimously. Project Recap Willowood Pool opened in 1987 and is 13,319 square feet with an adjacent splashpad. It was asked if work should pause and look at rebuilding at the Willowood location to continue with the neighborhood pool concept. The cost would be approximately $11 to $15 million and an additional $2 million for the parking lot or should focus be to continue to refine the Aquatic Center Plan. If Willowood Pool were replaced, it is anticipated an additional pool for the city would be needed within 10 to 15 years. Review Refined Aquatic Center Plan Draft The Aquatic Center plan could be reduced in size from 20,000 square feet to between 18,000 and 19,000 square feet with a zero-depth pool, lap lanes, diving boards, water slides and a separate lazy river. It was previously determined a lazy river would be a high priority for a new Aquatic Center. A shallow area for toddlers would be possible. Some items which need to be discussed are the cost estimate for the revised plan for the center to be placed at the Munier location, Page 1 of 2 Page 2 of 26 assessment of seating, possible space for future racer slide, and areas for rentals. If another location were selected, elevations and utilities would need to be looked at, and to have it removed from residential areas due to noise from the facility. Review Willowood Assessment A visual assessment of the Willowood pool focused on pool basins, perimeter deck, pool piping, mechanical and filtration systems, splashpad and buildings. The suspected condition of pool piping is fair to poor based on age and history. The mechanical and filtration systems are fair to poor. The wading, training, and lap pools are fair to poor with a great part to concrete failure and movement causing stress cracks. The splash pad's condition is fair as this feature was added in 2001. Condition of the buildings is fair, however generally outdated and floor cracks throughout. In addition, due to safety concerns, the use of underwater lights was discontinued for swimming at night. Some overhead lights have failed and the brackets supporting the overhead lights are corroding. The wood trellis structure in the concession area has deteriorated significantly. It is anticipated it would take 10 to 12 months to repair the Willowood Pool and a significant amount of time would be lost for the pool to be open. A replacement pool would last approximately 15 to 20 years. A presentation of information will be made to the Marion City Council in July on the possibilities to rebuild or replace the Willowood Pool or review a scaled-down Aquatic Center on Munier Road. Additionally, the Willowood location may be converted to a park if an Aquatic Center is built at the Munier location. It is anticipated that a decision will be made in August. Adjournment The meeting adjourned at 6:30 p.m. The next meeting will be Monday, July 13, 2026, at 5 p.m. at Marion City Hall, 1225 6th Avenue, Marion.

This allows planning to factor in costs associated with maintaining the current facility until such time it is replaced or improved. The physical conditions assessment report builds on reporting from the Outdoor Aquatic Center Feasibility Study conducted in 2021. A site visit was completed by Waters Edge Aquatic Design engineering staff on March 25, 2026, to conduct a visual assessment. Pools were not operational at the time of the visit, and invasive, hands-on testing was not performed. Willowood Park Pool Page 1 of 22 July 2026 Page 4 of 26  Willowood Park Pool Physical Conditions Assessment Executive Summary At nearly 40 years old, Willowood Pool is operational but showing signs of its age. The facility is expected to continue to serve the community in the near term, however primary components have reached, exceeded, or are near the end of their useful life. Additionally, the pool consists of an outdated layout and character and does not reflect modern aquatic recreation trends. Conditions of primary components range from fair to very poor. Primary components showing signs of deteriorating conditions include pool decks that are moving, pool basins that are cracking with significant deterioration in the structure of lap pool’s deep end, ageing mechanical systems and piping, and settlement of the filter building, all requiring ongoing levels of maintenance and repair. It is possible for the facility to continue to operate with ongoing maintenance and repair, likely increasing in cost and magnitude over time. It is estimated that within approximately five (5) years, the level of deterioration will be such that the effort, resources, and/or cost will be impractical or unfeasible. Ongoing maintenance costs may range from 10’s to 100’s of thousands of dollars over the next five (5) years. An extensive renovation to extend the facility’s life may require an investment of $5 Million - $8 Million, excluding costs for parking or other site improvements, and would maintain some original elements. Comparatively, full replacement of the pool and splashpad may require an additional +/- $2 Million, which would include all new basin(s), unlike the extensive renovation. Page 2 of 22 July 2026 Page 5 of 26  Willowood Park Pool Physical Conditions Assessment Existing Marion Pool Conditions The Marion Pool is in Willowood Park, at approximately 35th St. and Parkcrest Ct. The original facility opened in 1987 and offers a competition-focused 50-meter lap pool, separate shallow wading pool, and separate shallow training pool. In 2001, a splash pad was added to the park, however, currently operates independently from the pool (non- pool users can access the splash pad). The parking lot is located west of the facility, and residential property surrounds the facility on the north, east, and south sides. The Marion Pool offers approximately 13,391 s.f. of water surface and holds approximately 537,863 gallons. The pool has continued to offer the same traditional design and amenities for nearly 40 years. Overall, the facility is in poor to fair condition but offers a traditional 1980’s pool character with minimal updates since its inception. Waters Edge Aquatic Design most recently provided an onsite visual assessment of the pool and pool systems at the Marion Pool in the spring of 2026. A summary of that visit follows below. Pool and Pool Systems Wading Pool The wading pool is 1’0” in depth and predominantly serves babies, toddlers, and very young swimmers. There are no play features. Perimeter decking is experiencing concrete failure, particularly at corners. The wading pool offers a skimmer gutter style, which is a dated style. Wading Pool Skimmer Gutter Page 3 of 22 July 2026 Page 6 of 26  Willowood Park Pool Physical Conditions Assessment The basin structure is in poor to fair condition, with some cracking in the basin structure. All four corners of the pool structure and deck continue to experience stress cracking, presumably from vertical movement of the pool deck, which requires patching and repair on an ongoing basis. Additionally, staff reports that the floor drain in the basin (used for seasonal drain) does not seal tight anymore unless caulked by the staff. Training Pool The training pool ranges in depths of 2’0” to 3’0”, and predominantly serves younger children. There are no play features. Perimeter decking is experiencing concrete failure, particularly at corners. Training Pool The basin structure is in poor to fair condition. The walls are in better condition than the floor, as there are shrinkage cracks in each panel of the floor construction. The shrinkage cracks should be repaired and filled in. Wading and Training Pool Deck The area pool deck is experiencing vertical movement causing stress cracks in the corners of the pools and differential offsets in the joints on the pool deck. The resulting movement in the deck has resulted in differential offsets as much as 3/8” to 1/2”. There is also a significant amount of shrinkage cracks in the panels throughout. Condition is poor to fair. Page 4 of 22 July 2026 Page 7 of 26  Willowood Park Pool Physical Conditions Assessment The area includes three shade structures. The posts for the shade structures are in good condition, but the shade fabrics are faded and worn. Shade Structure Lap Pool The lap pool ranges in depths of 3’6” to 13’6”. It is comprised of eight, 50-meter lanes with six, 25-meter cross-directional lanes. Two, 1-meter diving boards utilize the deep end of the pool. The concrete is showing failure along the perimeter decking and throughout the pool basin walls and floor. City staff have performed spot repairs and recoated surfaces to maintain operation over the years. Concrete Failure – Perimeter Decking Concrete Failure – Pool Basin Floor Page 5 of 22 July 2026 Page 8 of 26  Willowood Park Pool Physical Conditions Assessment Concrete Failure – Pool Basin Floor Concrete Failure – Pool Wall In general, the shallow portion of the pool basin is in better condition than the deeper portions and is in fair condition. However, each corner of the pool structure has stress cracks in the basin as well as the pool deck, as movement in the pool deck is seemingly adding stress to the pool deck and pool structure. The area of most concern is in the deep end of the pool basin, and it is in very poor condition. The concrete in this area shows a significant amount of what appears to be D-cracking (durability cracking) in the concrete. D-cracking is a deterioration of the concrete from freeze-thaw cycles. This cracking appears to be more evident in areas where moisture would collect when the pool is empty during the cold winter months- which includes low lying areas and in seams in the structure. The deep end floor is spalling and raveling in the deep end. City staff patches spalled areas of the concrete each year as the condition worsens. Repairs that do not extend through the entire structure are temporary and require reconstruction after a short time as the concrete beneath the repair delaminates. The main drain structure concrete is likely softening rapidly. Lap Pool Deck Similarly to the wading and training pools, the main pool deck is experiencing vertical movement, causing stress cracks in the corners of the pools and differential offsets in the joints on the pool deck. The resulting movement in the deck has resulted in differential offsets in the joints and seams. There is also a significant amount of shrinkage cracks in the panels throughout. Overall condition is poor to fair. Page 6 of 22 July 2026 Page 9 of 26  Willowood Park Pool Physical Conditions Assessment The worst of the vertical movement appears to be on the south side of the pool, where the deck appears to have settled more than 1”, and perhaps as much as 2 to 3” near the filter building. The deck area on the east also has large gaps within the joints/seams, along with differential settlement. Pool Piping The piping for the pools is made of ductile iron for larger pool branches and threaded red brass piping for the inlets. There have been recent pipe breaches that city staff has repaired, causing significant water loss. However, it is believed that there is not currently any pipe breaches or water loss. City staff recently pressure tested the piping systems this spring to confirm this. The pipe materials are believed to include durable materials, however, the overall condition and remaining life before large-scale breaches occur is unknown. It is suspected that conditions range from poor to fair based on age and history. Pipe Break Page 7 of 22 July 2026 Page 10 of 26  Willowood Park Pool Physical Conditions Assessment Mechanical and Filtration The filtration system is made up of a vacuum Diatomaceous Earth (DE) system. The filtration system is functional with newer elements but is difficult to service and maintain; the filter requires significant efforts to manually clean the filters. Pool pumps and additional piping are in a room below grade under the main filter room, accessible by a ladder. DE Filter DE Filter Cartridges Mechanical Area Below Grade Pumps and Piping Ladder Access The system includes submerged valves with extended operators. Many of the valves have been replaced but are still a challenge to operate due to the length of the operators. Calcium hypochlorite is used for disinfection and is functional. Acid is used for pH control and is housed in a separate room. The acid room is experiencing rusting from acid fumes. Page 8 of 22 July 2026 Page 11 of 26  Willowood Park Pool Physical Conditions Assessment Overall conditions of mechanical and filtration systems are poor to fair. Rusting in Acid Room Pool Lighting The pool area includes both overhead and underwater lighting, originally intended for night swimming. The infrastructure has deteriorated and staff has discontinued the use of the underwater lights and any swimming at night over safety concerns. This includes the condition of step-down transformers located beneath adjacent benches and with the lights themselves. The overhead lights have some lights where the seals/gaskets have failed and the light fixtures have taken on water, but the lighting still functions in a limited manner and is used primarily for security lighting when the facility is not open. Brackets that support the fixtures are corroding.

The splash pad shares the same treated water as the swimming pool and includes a system that pumps water through the spray features. Splash Pad The spray features have aged and coatings have faded but still appear in fair condition. The features will need to be recoated in the near future. The system includes solenoid valves to control water through the features, which have been recently replaced due to failure. The splash pad deck is weathered and stained, but in fair structural condition. Page 11 of 22 July 2026 Page 14 of 26  Willowood Park Pool Physical Conditions Assessment Buildings There are two structures affiliated with the pool, including the bathhouse and concessions/mechanical building. The bathhouse contains the admission area, men’s and women’s restrooms, and staff/administrative areas. Both buildings appear to be in fair condition and provide reasonable support for swimming activities, outside of comments shared below. Entrance and Bathhouse The entrance to the facility is an outdated, gender split entry, meaning guests must enter the pool area by entering either the men’s or women’s restroom first. There are clear skylight panels throughout the restroom areas, and they are brittle and break. Staff noted that they believe the ridge beam and joists under the skylight are rotting and deteriorating. The finishes and lighting throughout the bathhouse are outdated, and there is minimal air-conditioned space in the facility. The paint coatings on the walls have faded and peeled. They should be sandblasted and repainted. Page 12 of 22 July 2026 Page 15 of 26  Willowood Park Pool Physical Conditions Assessment Admission Area Skylight Panels Staff/Admin Area Restroom Areas Additionally, there is a substantial crack in the floor and wall structure at the south end of the filter structure. It appears that the building footings on the south end have settled significantly, causing this crack and separation in the structures. This particular element pushes the building to poor to fair condition. Page 13 of 22 July 2026 Page 16 of 26  Willowood Park Pool Physical Conditions Assessment Crack in Structure A wood trellis structure is located between the bathhouse and filter building, providing shade for guests in the concessions area both inside and outside of the enclosed pool area. The wood structure has deteriorated significantly and “racked” due to lateral instability. The structure should be removed and replaced. Trellis Shade Structure Page 14 of 22 July 2026 Page 17 of 26  Willowood Park Pool Physical Conditions Assessment Conditions Summary At nearly 40 years old, the facility has surpassed the original design life and is reaching the end of its expected useful life. A summary of conditions is provided below for each of the primary components of the facility, ranging from Very Poor to Great condition. Pool Piping ranges in condition due to age, size, and material variations throughout the complex. There is a history of pipe leaks and breaks, indicating deteriorating conditions in spot locations at minimum. Very Poor Poor Fair Good Great Pool Basin – Wading and Training Pool Pool Basin – Lap Pool Deep Shallow Pool Deck – Wading and Training Pool Pool Deck – Lap Pool Pool Piping Mechanical and Filtration Splashpad Buildings Filter Bathhouse Bldg.

Additionally, areas to watch for widespread or larger failure have been identified for several of the primary components. • Estimated Remaining Life: Time frame for conditions to deteriorate further • Risk Level: Severity of Impact + Likelihood in Next 5 Years Estimated Overall Risk Level Areas to Watch for Remaining Useful Widespread or Life Larger Failure Pool Basin – Wading 1 – 5 Years Medium-High - and Training Pool Pool Basin – Lap 0 – 5 Years Medium-High Spalling in deep Pool (deep end) end floor and/or main drain Pool Deck – Wading 1 – 5 Years Medium - and Training Pool Pool Deck – Lap 1 – 5 Years Medium - Pool Pool Piping 0 – 5+ Years Medium-High Failure in larger (age + history) diameter ductile iron pipes and/or red brass inlet pipes Mechanical and 1 – 5 Years Medium-High - Filtration (components) 6 – 10 Years (header pipe) Splashpad 6 – 10 Years Low-Medium - Building - Filter 1 – 5 Years Medium-High Filter building (settlement) settlement Building - Bathhouse 6 – 10 Years Low-Medium Page 16 of 22 July 2026 Page 19 of 26  Willowood Park Pool Physical Conditions Assessment Improvement Options Near-Term Outlook and Considerations Until such time as the pool has a major renovation or is replaced, we anticipate the continuation of the current repair efforts and potential larger scale failures. It is difficult to predict an end-of-life date, but we believe the next 5 years is a likely time frame for which conditions deteriorate such that the facility becomes unfeasible. During this time, we anticipate the current adverse conditions will continue, causing staff to perform ongoing repairs, including but not limited to the following: • Spalling of the pool shell, particularly in the deep end floor and main drains. The amount of spalling and repair is expected to accelerate during the next 5 years. • Repair of stress cracks and spalling at corners of each of the pools: wading, training and main pool. • Monitoring vertical offsets in the pool deck and grinding to remove potential trip hazards. • Monitoring of the filter building settlement and cracking. If footings continue to settle, stabilization may be needed. • Repairs to the filter, including replacement of filter elements and socks. • Repainting of the pools (scheduled for 2027). This is likely the most significant anticipated repair cost. • Replacement of the main pool pump seals, and potentially the impeller (which is potentially original?). Beyond the continuation of anticipated repairs, other conditions are more unpredictable and could present more widespread failure. Failure would include a condition where water loss is at a point that it is not feasible to continue operation. These conditions could include: • Large-scale spalling of the deep end pool floor or main drain structure. If the degradation is significant enough, it could create leaks through the pool structure that would cause water loss. The location that would create this amount of loss would be most likely at the seams in the main drain. • Failure or breaches in the larger diameter ductile iron pipe systems for the main pool. These systems include the main drain pipe, gutter pipe, or inlet piping Page 17 of 22 July 2026 Page 20 of 26  Willowood Park Pool Physical Conditions Assessment headers. These can be deeper lines and it is sometimes difficult to pinpoint the location of breaches in this piping. • Failure in one or more of the red brass inlet pipes for the main pool. The red brass pipes include short branches connected to the larger ductile iron pipe branches. If there are breaches in an inlet pipe, it is often easier to locate and perform a spot repair. Failures described above generally don’t result in an obvious single catastrophic event but are revealed through a dramatic increase in water loss and requirement to constantly fill the pool. It is not uncommon for a swimming pool of this age and condition to lose 2” of water from the level of the pool each day. For the existing pools, this loss in depth equals a loss of 17,000 gallons per day, or approximately 1,500,000 gallons for the season. While a catastrophic level of water loss is subjective, over 12” of water loss per day becomes very significant and equals 105,000 gallons each day. This equates to 9.5M gallons for the season. With the total volume for the pools at approximately 540,000 gallons, this would fill the pools once every five days. Large scale repairs to the pool structure or locating and isolating individual pipe leaks can easily be in the $10,000’s magnitude of cost. Widespread piping failures that require large areas of demolition and piping repairs can be in the magnitude of cost of multiple $100K’s on up. The following graph on the following pages summarizes the primary components, their estimated remaining useful life, overall risk level, and anticipated or possible near-term actions identified in this section for easy review.

If corrections were to be made to extend the life, the facility would still be a dated design stemming from the 1980’s. Modern aquatic centers generally have a different character to meet the current expectations of the community it serves. However, if a plan were adopted to extend the life of the facility with roughly its current configuration, the following large-scale renovations would occur. • Removal and reconstruction of the wading and training pools (likely in a different leisure pool construction) • Reconstruction of the main drain structures and deep end floor • Repair in spot locations in the remaining pool basin • Replacement of the pool gutter grating • Replacement of pool piping • Removal and replacement of the pool deck • New overhead and underwater lighting • Reconstruction of the filter building and pool filtration systems • Extensive renovation of the bathhouse • Reconstruction of the splash pad The portions of the facility that would be salvaged include the repaired portion of the lap pool, along with the bathhouse structure. However, the remaining life of the salvaged main pool is currently unknown given the D-cracking evident it portions of the pool structure. This condition may also occur in the salvaged portions of the pool, which would limit the remaining effective lifespan. Core samples could be taken from the pool structure to determine the condition of the remaining structure. Given the size of the facility (13,400 s.f. pool area plus an additional splashpad), we would anticipate a magnitude of cost in the range of $5M to $8M* for an extensive renovation outlined above. Comparatively, if the swimming pool and splashpad were to be fully replaced with a new pool and splashpad of the approximate same size and character, while maintaining the level of improvements in building spaces as noted above, the magnitude of cost may increase +/- $2M*. In this case, the pool basin, piping, deck, and all mechanical systems would be new. *Parking and other site improvements not included.
