Mr. Hubmer stated the change to coarse grain sand and new <br />chemical treatment processes had a better propensity to remove the manganese. <br />Councilmember Stille asked what color the water was after it went through the filter. <br />Mr. Hubmer replied it was clear; crystal clear! <br />Councilmember Thuesen asked how soon the filter would need changing and would the City <br />know when it needed to be changed before the water turned brown. <br />Mr. Hubmer replied the life span of the filters is 20 to 25 years. He indicated a slowdown would <br />be noticed over time. Mr. Hubmer stated testing for manganese and tracking concentration <br />levels would continue. <br />Motion by Councilmember'I'huesen, seconded by Councilmember Gray, to Approve Resolution <br />07-021, a Resolution Awarding a Bid and Ordering Improvements for the 2007 Water'freatment <br />Facilities Improvements to Shank Constructors, Inc. in the amount of $375,600. <br />Motion carried unanimously. <br />B. Resolution 07-022; Ordering Changes to the Assessment Policy for Public Roadways <br />Mr. Hubmer explained Resolution 07-022 was being modified to reflect that all City streets, <br />including concrete streets, would be reconstructed with bituminous asphalt pavement. He stated <br />it clarifies the water service replacement cost assessment and general clarifications. Mr. Hubmer <br />reported the update included routine drainage and storm sewer replacement, sidewalk <br />replacement, new sidewalk installation, and updated front footage diagrams and calculations. <br />Mr. Hubmer reported the comparison of concrete versus asphalt was discussed. He stated <br />concrete is generally quieter and creates a smoother ride, is lower in initial cost, flexes with the <br />freezing and thawing of the subgrade, the mixture could be adjusted to address specific concerns <br />such as rutting or cracking, and it is less expensive to repair. <br />Mr. Hubmer stated, in comparison, concrete is generally louder, higher in initial cost, the rigid <br />material did not flex with freezing and thawing of the subgrade which leads to increased <br />breakups at manholes and gate valves. He indicated concrete provides a longer -lasting surface <br />that is more costly to maintain or replace over time. <br />Mr. Hubmer stated the 2007 Street Reconstruction Project bid for asphalt and concrete <br />alternatives for the streets and alleys came in at $272,800 and $490,100 respectively.
