Mr. Miller said that when he met with Dana with the Fountain Hills Sanitary District they were not keen on the idea of locating this at their property, and he was Town Council Special Work Session of May 11, 2021 3 of 3 not keen on using park property. He said that they agreed that the ideal location for this would be at the Kiwanis Park.The costs for this option are scary, and they would need to do further research with this option. CONCLUSIONS Use Decision Tree for liner replacement timing Localized repair if liner damaged by known event Plan for multi-faceted lake water reuse strategy Additional coordination will be required Mr. Miller asked to review the slide ESTIMATES OF PROBABLE COST-Total Relining Project Costs. He said that whether or not the liner can last another nine years, it would make sense to sock away money for when replacement is needed. Councilmember Scharnow said that he would like to have more work on the concept of a reservoir. Mr. Miller said that he would suggest they start working toward the solutions on a "pay as you go" basis. Councilmember Friedel said that they also need to keep the Sanitary District involved in the project. Mr. Miller totally agreed. Councilmember McMahon asked if they needed to put together a committee on this issue. Mr. Miller said that at this point, he believed they had a good group of professionals addressing the project, but one thing that they will need to have further discussion on is the fish. Vice Mayor Spelich asked if he had heard correctly that the structure itself needed work. Mr. Corbin said that as they looked into it further,they determined that it was more to do with things that had been left over from construction.The structure itself did not look to need restructuring. He said that if there was an opportunity to look further at the structure under the water line, it is something that would be recommended.Vice Mayor Spelich said that he felt it was imperative that at some point they look into the structure of the fountain itself. Mr. Miller said that he agreed as it was already 50 years old. Mr. Miller said that they have a done a great job, and what is so helpful is that they have been involved in a similar project in the past. 4.
