study. He then turned it over to Rachael Goodwin, Community Services Director. She said that
this was the "book end" of the study.The consultants are here tonight to present on moving
forward.This is a very broad scope of what options they will have. Also, it is conceptual. When
they get to actually moving forward, there would be some fine-tuning needed. She then invited
up Mike Caruso, who began a PowerPoint presentation which addressed:
CONDITION ASSESSMENT SCORING RECAP
For each asset they looked at the Consequence of Failure and Likelihood of Failure and put them
into a chart which was shown.
PROJECT RECAP
Vast majority of equipment is in good working order
Immediate recommendations
Replace check valves (have been ordered)
Repair pump house intake screen (in progress)
Install arc flash labels on electrical equipment(to happen this week)
Upgrade to PLC control (too new to determine)
LINER REPLACEMENT DECISION METHODOLOGY
Fountain liner in good condition
Continued Periodic Evaluation
What If? Known (potential) damage event or future evaluation results show concern
LINE REPLACEMENT DECISION METHODOLOGY: Short Term

Caruso said that they did. Councilman Magazine asked what a known event would be. Mr. Caruso
said that if it is something they know about, it would be a known event.

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.
