Consider and take action on a resolution to ratify the contract with D. Wagner Construction Co., Inc. for the emergency repair of the 42-inch gravity sewer line on Butler Road in an amount not to exceed $132,600 (Director of Public Works)

Due to the urgency and complexity of the repair, Staff contacted three reputable contractors to evaluate and provide proposals and the results are as follows:

Base Construction Co. $ 135,976
