BACKGROUND During the Summer of 2024 Water District 125 had a project to update some of their watermain along 51s' Ave S eventually becoming Macadam Road S. Working with the District final overlay paving was able to be held off with the contingency that Water District 125 would give us a lump sum payment for the paving costs saved in order for the funds to be used in a bigger city performed overlay that would capture the work area from the water districts watermain project. DISCUSSION A takeoff was performed using the plan set from the watermain project showing how much of the road would have been overlayed. Converting this area into a price per ton of asphalt a unit price was finally applied to show the cost to purchase and install the asphalt using recent bid cost data. FINANCIAL IMPACT No contribution from the City. This is to accept funding from Water District 125. RECOMMENDATION Council is being asked to approve the cost -share agreement and to authorize signature of the contract with Water District 125, therefore accepting the lump sum payment of $112,336.40, which includes a contingency of $10,212.40.
