5.2. Discuss garden maintenance for the garden bed within Cummings Park and rain garden on Nursery Hill. Lucas Miller. 5.2.1. There is no plan in place to maintain the Art Larson Memorial Garden and the Nursery Hill rain garden needs weed removal. Andrew is going to investigate the Memorial Garden. Joel will look into the rain garden. 5.3. Discuss pump proposal and Geocell information for the Cummings Park retaining wall as part of the 2026 PMP project. Brad Fisher (Consultant from Bolton and Menk. Audio call so this was done at the beginning of the meeting). 5.3.1. Various options were presented and discussed that had been presented to the City Council. The retaining wall will be replaced with a slope stabilization product called Geocell. The pump system improvements considered are options 1, 2, 3 and described in the presentation document. • Option 1 was essentially the existing system with a logging device. Cost estimate $14,000. • Option 2 would include a new culvert that would have the pump system placed inside as well as have a remote monitor included. Public works would still need to come out to turn on the pump, but they would be able to monitor the level remotely. Cost estimate $112,000. • Option 3 would be for a full lift station type design that would be just like the other existing lift stations in the city. This would be significantly more expensive. Rice Creek Watershed indicated some interest in possibly providing financial assistance. Cost estimate $500,000+ The Board recommended Option 2. It would allow for future improvements but keeps the cost in check. The city recommended against the silt removal part of the improvement. 5.3.2. The DNR is onboard with changing the criteria for pump on/off but the change needs to be requested by City Council. The city is waiting to get this changed after the new improvements in 2026. 5.4. 2025 Purple loosestrife assessment 5.4.1. August is the best time to identify any Purple Loosestrife. Joel, Kent and Renee will look together later in the summer and get approval from the DNR to cut/treat plants in the water. Those that are out of the water can be pulled without a permit. 6. NEXT MEETING: Tuesday October 14, 2025, at 6:30 PM at City Hall. 7. ADJOURN
