ARDEN HILLS CITY COUNCIL—APRIL 30, 2012 8 Mayor Grant asked how much the City has spent over the last five years on this main. Public Works Director Maurer explained the City has spent a great number of man hours each time this main breaks, in addition to tearing up and repaving this roadway. He stated the City was moving to plastic pipes for all the new or replaced water mains to eliminate this problem. Councilmember Tamble asked if the traffic along this roadway contributed to the concerns with this main. Public Works Director Maurer stated this line has only been in the ground since 1988 and he did not think that traffic levels were the concern; the problem is the material the pipe is made of reacting with the native soils. Councilmember Tamble questioned if the use of the water funds for this water main would hinder the City from completing other tasks. Public Works Director Maurer stated there were enough funds in reserves to cover this expense. Mayor Grant expressed concern with the number of failures in 2010 and 2012. He stated the pipe was deteriorating and by replacing it now, the City could make an informed decision and not have to act in the future in an emergency situation. The City would also avoid future main break expenses. City Administrator Klaers inquired why the contract quotes were so different. Public Works Director Maurer indicated the timing of the work was a concern for Ellingson, while GM Contracting was available to complete the work in a timely manner. Mayor Grant asked the estimated life expectancy of this pipe. Public Works Director Maurer indicated the pipe was designed to last as long as other pieces within the City's system. MOTION: Councilmember Holmes moved and Councilmember Tamble seconded a motion to approve a contract with GM Contracting to replace the Old Highway 10 water main for an expense not to exceed $60,408.40. The motion carried unanimously (4-0). 9. UNFINISHED BUSINESS A. Valentine Park Bids Public Works Director Maurer provided the Council with a project history on Valentine Park.
