308 <br />backlog increases from current assumptions as index levels reduce from 70 to 60 <br />309 <br />within the 2014 to 2034 timeframe. <br />310 <br />experiences and recommendations gleaned from other agencies. <br />311 <br />Mr. Culver reviewed the City's current maintenance budget for seal coating at <br />312 <br />$220,000 annually from the General Fund, and an annual budget of $960,000 for <br />313 <br />a two inch and/or full depth mill and overlay, with an average $100,000 from <br />314 <br />State Aid funds. However, Mr. Culver noted that the budget also needed to <br />315 <br />provide for any annual sidewalk or curb & gutter installations, or other elements <br />316 <br />that came from that Local Street Maintenance Fund. <br />317 <br />Ak <br />318 <br />Mr. Culver advised that staff's recommendation, which they would present to the <br />319 <br />City Council at their April 13, 2015 Work session, would be to suspend the <br />320 <br />current seal coat program, and shift the current allotted seal coat funds of <br />321 <br />$220,000 to the annual mill and overlay program to accelerate this corrective <br />322 <br />action, and starting in 2015. Mr. Culver admitted that staff remained unsure when <br />323 <br />the City would stop seeing the delamination distress; and clarified that typically <br />324 <br />staff remained a strong proponent of the advantages of performing regular seal <br />325 <br />coat applications. Mr. Culver advised that it should4be known within one to two <br />326 <br />years if the delamination was going to stop, but probably not before then. Mr. <br />327 <br />Culver noted that typically, the City got a longer life from seal coating than for <br />328 <br />this current delamination issue. <br />IR�� <br />330 Discussion included staff s intent to continue crack sealing of lateral cracks <br />331 forming due to expansion and contracting of pavement; results by 2016 and/or <br />332 2017 for existing pavements not exhibiting delamination if not seal coated; other <br />333 communities experiencing the same issue and taking similar actions to determine <br />334 the cause and eff ct; an n annual review of the seal coating issue for future <br />335 <br />336 <br />337 eFheiscussionincluded those ogencies and communities in the same <br />338 and the attention o MnDOT and research boards in defining the <br />339 problem and recommended ges if beyond the scope proposed. <br />340 <br />341 <br />Beyond using the super pavement mix, Mr. Culver advised that staff had taken <br />342 <br />additional steps for decreasing air voids in current specifications along with <br />343 <br />experiences and recommendations gleaned from other agencies. <br />344 <br />!Nember <br />345 <br />At the request Cihacek, Mr. Culver reviewed the information <br />346 <br />available from analysis and cost analyses from modeling, with staff firmly <br />347 <br />believing that the current seal coating program is hurting more than helping the <br />348 <br />roads. <br />349 <br />350 <br />Mr. Schwartz opined that staff may be able to make a connection based on future <br />351 <br />pavement index modeling and pavement maintenance practices. <br />352 <br />Page 8 of 17 <br />
