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.
