1412_311g- CITY COUNCIL WORK SESSION STAFF ORIGINATOR: Jason C. Wedel, City Engineer MEETING DATE: April 23, 2012 TOPIC: Lilac Street Pavement Management BACKGROUND On October 12, 2009, the City Council approved a joint powers agreement with Anoka County for the turn back of Lilac Street to the City. As part of this agreement, the City received $300,000 from the County for a future bituminous overlay of the existing street. Lilac Street is currently included in the City's 2012 overlay project. As part of the design of Lilac Street, we completed several pavement corings of the existing pavement and determined that the pavement is only 3- inches thick and is paved directly on top of the existing sand subgrade without any class 5 beneath it. The existing pavement is not in great shape and we believe performing an overlay will extend the life of the street another 10 -15 years. The other alternative is to reclaim the existing pavement, creating a new class 5 base with the reclaimed material, and pave 4- inches of new pavement on top of the reclaimed material. This would provide a structurally stronger street section that would have an estimated life expectancy of 30 -40 years. Anoka County is completing a massive pavement reclamation project at multiple locations within the County this year and I asked them to include Lilac Street as an alternate to their bids. The bid opening occurred on April 4th and the low bidder included an alternate price of $312,278.56 for Lilac Street. The County's price for reclaiming and paving 4- inches of new bituminous on Lilac Street is very favorable; however, it does exceed the $300,000 that the City received from the County when Lilac Street was turned back. There is funding available in the City's current pavement management budget due to previous years projects coming in under our estimates. DISCUSSION Staff would like the City Council's opinion on utilizing $12,278.56 of City pavement management funds to facilitate the reclaiming and paving of Lilac Street.
