" The barrier is located at the head end of tidewater and is co-owned with a private business (Chevron franchisee). The project includes acquisition and demolition of a gas station that lacks stormwater controls, fill removal and potential environmental remediation and construction of a new crossing at 144th. In 2018 Pierce County completed a Restoration Feasibility Study and alternatives analysis. The preferred alternative is to construct a bridge at 144th St NW, purchase and remove the existing gas station and daylight and restore over 200 feet of stream channel. WSDOT?s SR302 crossing, a partial barrier is located at tidewater only 330 feet downstream. WSDOT?s SR16 is located 0.65 miles upstream and is also a partial barrier. WSDOT designs are complete, and they are in permitting now with construction scheduled for 2022-23 under one contract ($25 -$30 million). Modeling the SR302 replacement, WSDOT found with the larger opening, there may be a 1.5 ft. head cut (channel incision) that propagates upstream to the 144th outfall, making the partial barrier a complete barrier to salmon. The project will have immediate benefits of providing unimpeded passage of ESA listed Chinook and steelhead, fall chum, coho and coastal cutthroat to more than 7 miles of Purdy Creek and tributaries upstream. The project also solves a current and future water quality threat. The project benefits from, and leverages WSDOT?s proposed fish passage projects at SR-302 and SR-16 planned for 2022-23 con
