Chairperson Kuzma asked for funding information. City Engineer Westby stated that in the next case it is recommended to reallocate $250,000 from the 2020 sealcoat budget towards this project for option three. He confirmed that could also be sufficient funding to complete options one or two. Councilmember Menth asked why one of the roads from the originally proposed project would not be selected. City Engineer Westby stated that option one, which proposes removing 3.5-inches of pavement and underlying aggregate base and repaving with 3.5-inches of new pavement at an estimated cost of $835,000, and option two, which proposes completing a full -depth reclamation at an estimated cost of $811,000 to 1.5 miles of streets would provide less than the standard pavement base section and therefore staff would not be confident that the expected lifespan of the improvements would be reached. He stated that staff would be more confident that option three, which proposes standard 2-inch mill and overlay improvements on streets in the Business Park 95 and Regency Ponds Additions, would provide pavement sections closer to today's standards to allow standard pavement management practices to be applied in the future. Staff is therefore more confident in achieving the expected lifespan on these 2.8 miles of streets so in Staff's opinion option three is the most cost-effective. Chairperson Kuzma asked the condition of the roads within Business Park 95 and Regency Ponds. Councilmember Menth asked the paser rating of Business Park compared to the other roadways originally included in the project. City Engineer Westby confirmed that the roads in Business Park 95 are in poor condition and provided photographs. He provided the different paser ratings. He explained that option three would be most cost effective with the limited funds the City has. Councilmember Riley stated that the City previously identified what it thought was the best idea, but it was found that the pavement was not conducive to the proposed improvement. He stated that it also appears that the priority has changed, and the recommendation better fits the change in priority because of the limited funding available. Chairperson Kuzma agreed that repairing 2.8 miles would be a better choice than 1.5 miles. Councilmember Menth stated that his concern would be that the Feasibility Report is not completed on the recommended roads and therefore it could be unknown as to the pavement thickness. City Engineer Westby explained that the roads in Business Park 95 should have been built to a higher standard, and that the roads in Regency Ponds have good PASER ratings and were more recently constructed and therefore should have a sufficient pavement section to allow for a 2- Public Works Committee / February 18, 2020 Page 2 of 3
