Mayor Stromberg called the Study Session to order at 5:32 PM.
Councilors Slattery, Graham, Jensen, Akins and Seffinger were present.
Councilor Rosenthal was absent.
Dr. Carol Voisin Ashland She spoke regarding the water master plan. She spoke that the cost has gone up and there will probably be an increase in water rates in the future. She explained that in 2012 it was told that by increasing rates by 10% it would give us what we need for water infrastructure. She spoke that another review is needed by Council. She questioned what will this do to our water rates. She spoke that it is important to assure the citizens that oversight and accountability are in place. She explained that there is no need to rush this and the importance of being transparent about cost.
William Shanor Ashland Spoke that he and his wife did a site visit. He spoke regarding E. Coli and the importance of the more you learn the simpler it becomes. He spoke that this is not as complicated as those appear to make it.
I. Update on Preliminary Design of a 7.5 Million Gallons a Day Water Treatment Plant
City Administrator Kelly Madding gave a background on the water treatment plant.
Seffinger arrived at 5:47 PM.
Deputy Public Works Director Scott Fleury gave a Staff report.
Akins questioned what will happen to the current water plant. Fleury explained that options would be brought back to Council regarding the current plant.
