Home

Discussion took place regarding locations of large potholes. Public Works Director Olson agreed to look at them. City Engineer Himmer recommended his intent be added to next month's Consent Agenda with the feasibility study and to call a public hearing. Motion by Commissioner Elvig, seconded by Commissioner Backous, to recommend that the City Council direct staff to prepare feasibility study for the 2011 Street Maintenance Program and schedule a public open house. Motion carried. Voting Yes: Chairperson McGlone, Commissioners Elvig and Backous. Voting No: None. Absent: None. Case #5.3 Consider Change Order for City Improvement Project #10-32; 176th Avenue Culvert City Engineer Himmer reviewed the staff report. Chairperson McGlone asked what material was used for the culvert. City Engineer Himmer responded it was corrugated metal, 42 inch. The road is 28 feet wide. Public Works Director Olson noted it was a hole the Staff was replacing annually. Chairperson McGlone commented the assumptions made by Staff were not accurate enough, and this happens repeatedly. He asked if bidding should be done in another manner or more borings should be conducted to assure accuracy. City Engineer Himmer explained the boring wasn't done in the middle of the road. Commissioner Elvig asked if the boring could be angled for a better reading. City Engineer Himmer explained the boring could be done at an angle, though it doesn't help to know the depth at that spot. He noted that if the money is going to be spent to do borings that may not be accurate, it could just as easily be spent to do the repair. Public Works Director Olson explained the borings that were done indicated 5 — 6 feet of muck on either side of the road. If there would have been a large discrepancy on either side of the road, there would have been a reason to explore with additional borings Staff gave the best estimate for use in bidding. Discussion took place on the bidding process and how to ensure the accurate bidding. Motion by Commissioner Elvig, seconded by Commissioner Backous, to recommend that the City Council approve the change order for Improvement Project #10-24; 176th Avenue culvert replacement, in the amount of $20,395.56.
