This project consists of the replacement of existing water and wastewater mains located within the Barton Hills Horseshoe Bend area, on Barton Skyway, Barton Parkway, Arpdale Street, De Verne Street, Wilke Drive, and Airole Way. The water system renewal includes approximately 9,451 linear feet of 8-inch and 12-inch water mains along with service lines to individual properties and associated appurtenances. The wastewater system renewal includes approximately 515 linear feet of 8-inch sanitary sewer lines, manholes, and service lines to individual properties.  Item 10 # 22-3482 Water &Wastewater Commission: November 9, 2022 Council: December 8, 2022 Due to the potential for unknown subsurface conditions, a 10% contingency in funding has been included to allow for the expeditious processing of any change orders.
