backlog increases from current assumptions as index levels reduce from 70 to 60 <br /> within the 2014 to 2034 timeframe. <br /> Mr. Culver reviewed the City's current maintenance budget for seal coating at <br /> $220,000 annually from the General Fund, and an annual budget of$960,000 for <br /> a two inch and/or full depth mill and overlay, with an average $100,000 from <br /> State Aid funds. However, Mr. Culver noted that the budget also needed to <br /> provide for any annual sidewalk or curb & gutter installations, or other elements <br /> that came from that Local Street Maintenance Fund. <br /> Mr. Culver advised that staff's recommendation, which they would present to the <br /> City Council at their April 13, 2015 Work session, would be to suspend the <br /> current seal coat program, and shift the current allotted seal coat funds of <br /> $220,000 to the annual mill and overlay program to accelerate this corrective <br /> action, and starting in 2015. Mr. Culver admitted that staff remained unsure when <br /> the City would stop seeing the delamination distress; and clarified that typically <br /> staff remained a strong proponent of the advantages of performing regular seal <br /> coat applications. Mr. Culver advised that it should be known within one to two <br /> years if the delamination was going to stop, but probably not before then. Mr. <br /> Culver noted that typically, the City got a longer life from seal coating than for <br /> this current delamination issue. <br /> Discussion included staffs intent to continue crack sealing of lateral cracks <br /> forming due to expansion and contracting of pavement; results by 2016 and/or <br /> 2017 for existing pavements not exhibiting delamination if not seal coated; other <br /> communities experiencing the same issue and taking similar actions to determine <br /> the cause and effect; and an annual review of the seal coating issue for future <br /> funding. <br /> Further discussion included those other agencies and communities in the same <br /> situation, and the attention of MnDOT and research boards in defining the <br /> problem and recommended changes if beyond the scope proposed. <br /> Beyond using the super pavement mix, Mr. Culver advised that staff had taken <br /> additional steps for decreasing air voids in current specifications along with <br /> experiences and recommendations gleaned from other agencies. <br /> At the request of Member Cihacek, Mr. Culver reviewed the information <br /> available from analysis and cost analyses from modeling, with staff firmly <br /> believing that the current seal coating program is hurting more than helping the <br /> roads. <br /> Mr. Schwartz opined that staff may be able to make a connection based on future <br /> pavement index modeling and pavement maintenance practices. <br /> Page 8 of 17 <br />
