PRIOR COUNCIL ACTION: February 19,2013-Council approved Resolution R2013-16 authorizing an intergovernmental cooperation agreement for the sharing of certain costs related to micro-surfacing improvements between the City of Decatur,Hickory Point Townslup,Mount Zion Township and the County of Macon,Illinois. This agreement is in effect until December 31,2018. i June 15,2015-Council approved Resolution R2015-79 appropriating$140,000 of Motor Fuel Tax funds for the purpose of II micro-surfacing streets and highways as listed and described as part of the City's Micro-Surfacing Project. i BACKGROUND: Micro-Surfacing projects are focused on slowing the deteriorarion of pavements that are e�eriencing moderate wear. The actions of sun,freezing,traffic and age all combine to deteriorate asphalt pavements. Micro-surfacing is designed to seal and protect the pavement surface and slow deterioration thereby delaying the need for more expensive treatments such as a mill and overlay or total reconstruction. The work involves coating the etcisting pavement with a thin mix of asphalt and aggregate which serve to correct minor surface distresses and extend the life of the pavement. When performed at the right time with only moderate wear on the street,micro-surfacing treatments can last from 5 to 7 years. The City has perfomied tow micro-surfacing projects in the past with good results. The Macon Counry Highway Department has also placed micro-surfacing on several County highways,as has some of the nearby Townships. The City of Decatur along with Hickory Point Township,Long Creek Township,the Village of Long Creek,the V'illage of Mount Zion and Macon County propose a combined project that will use micro-surfacing as a cost effective way of protecting streets in each jurisdiction. Each agency party to this agreement has selected streets appropriate for micro-surfacing treatment and are combining them into one contract for the purpose of receiving more competitive bids which will reduce project costs. The City will act as the lead agency for the combined micro-surfacing project and pay the total cost of the work,with the other agencies agreeing to reimburse the City for the work completed on the streets in their jurisdiction. The City has an existing agreement with the County,Hickory Point Township,Long Creek Township,and Mount Zion Township to combine micro- surfacing projects. Mount Zion Township Y�as opted out of this year's project. The agreement with the Villages of Long Creek and Mount Zion are only for projects in 2016. The City's portion of the project will include portions of the Greendell neighborhood and a section of Boiling Springs Road. See attached location maps for informarion. Hickory Point Township plans to place a cape seal along Boiling Springs Road and the City will pay for the 837 foot portion that is in the City. A cape seal is similar to a chip seal that is covered with a micro-surface. It provides for a longer life than a simple micro-surface. SCHEDULE: Design work on ttris year's micro-surfacing project is currently underway. It is plavned that the combined project could begin as early as May 2016.
