MINUTES OF THE ORONO CITY COUNCIL MEETING Monday, July 11, 2011 7:00 o'clock p.m. • (9. PAVEMENT MANAGEMENT PLAN UPDATE, Continued) Kellogg indicated it is since during a mill and overlay only an inch and a half of bituminous is removed rather than down to the aggregate base. The duration or life of the roadway is completely dependent on the base of the road. Willow Drive South last year was a mill and overlay and was a candidate for that type of work because there was a better aggregate base under that roadway. Kellogg requested direction from the City Council on how they should proceed with the CIP. Franchot commented that this is really good data on the condition of the roads within the City and that it is part and parcel of the discussion that the City Council had during their work session earlier this evening concerning the City's available road funds. Kellogg noted Orono Orchard Road is on the C]P for next year because the Metropolitan Council has indicated an interest in partnering with the City on that project. The latest agreement is at the Metropolitan Council for their review and that in his opinion there will only be minor changes to it The Metropolitan Council should pick up approximately 30 percent of the costs on that project since they have an interest in installing a new parallel force main. There is an existing force main but there are aging and capacity issues with that pipe. Printup asked when they expect to hear back from the Metropolitan Council Kellogg indicated the person who was dealing with this issue was on maternity leave and she has just returned this week. Kellogg stated he anticipates hearing back within the next two weeks. Kellogg noted Orono Orchard Road is not a state aid route and that the road will basically remain the way it is. McMillan commented at the present time there are some different opinions on the City Council regarding the roads within the City and how they should proceed forward but that she would like to proceed forward with designating certain roadways for improvements next year. Kellogg noted it was the City Council's decision approximately one year ago to look at Old Crystal Bay Road to address the deteriorating condition of the roadway as well as safety issues. If the Council's direction is to relax some of those standards that were addressed in the design, they can still go back and put together a revised design that is cheaper but it may not accomplish all the goals. Kellogg noted there were some comments by the residents that a mill and overlay would solve the problem. Kellogg indicated he would not recommend that based on how the road was originally constructed in 1962. Those findings were presented to the City Council last October in the feasibility study. Following the direction of the Council, five soil borings were conducted, with results that one of the soil borings showed four inches of bituminous and six inches of aggregate base but that the other four soil borings showed no aggregate base at all. Kellogg indicated that if they take off an inch and a half or two inches of surface, they will not have any structural integrity to support that roadway due to the lack of the aggregate base. Kellogg indicated the City probably will not get five years out of it.. There is also some petroleum contamination in the area that will need to be addressed. Kellogg noted the City undertook a process eight or nine years ago to replace the water main from Willow Drive along Old Highway 12 on the north side which goes to Old Crystal Bay Road. There has been a • fairly significant break frequency of that water main over the years and the fear is that potentially the users of the water system on the south side of Highway 12 would be out of service for a period of time should that water main break. The City has undertaken three projects over the years to replace part of that Page 12 of 19
