As part of safety and mobility improvements on SR 305 from Poulsbo to Winslow Way, Parametrix designed three fish barrier removal projects on the corridor at Sam Snyder Creek, Klebeal Creek, and Murden Creek. The projects are near intersection safety improvements in the SR 305 corridor between Bainbridge Island and the City of Poulsbo. Parametrix prepared the hydraulic reports, PS&E, hydraulics design, constructability, staging, traffic control, cultural, and floodplain review/impacts and is supporting WSDOT as an extension of staff for environmental permitting, including the Pre-Biological Assessment and NEPA.
- Sam Snyder Creek – The fish barrier removal project near Totten Road replaced two existing 270-foot-long, 36-inch-diameter concrete culverts with a new 239-foot single-span steel girder bridge.
- Klebeal Creek – Near Suquamish Way and the Suquamish Clearwater Casino, this effort replaced an existing 201-foot-long, 48-inch-diameter concrete pipe culvert with a new 150-foot single-span concrete girder bridge.
- Murden Creek – Near Sportsman Club Road on Bainbridge Island, this effort replaced an existing 152-foot-long, 5-foot-wide, 4-foot-tall box culvert with a new 114-foot single-span concrete girder bridge.
