This proposed project will build on the conceptual design alternatives presented by PSNERP by developing a preliminary 30% design. Replace the existing North Shore Road Bridge over the Tahuya River to restore normative tidal exchange, sediment and debris transport, and reconnect a historic distributary system. This project involves removing the existing 123 foot span bridge, removing fill material from within the tidal prism, installing a longer bridge to span the estuary, and revegetating fill removal areas. The project team will also investigate the feasibility of reconnecting a historic distributary channel system, and other identified habitat improvement elements as they are identified during the design process. Preliminary design development involves: topographic survey, geotechnical boring and analysis, structural engineering, civil/hydraulic engineering, cultural resource investigation, environmental research, landowner outreach, and project stakeholder coordination.
