Twanoh State Park Beach Restoration
Twanoh State Park, Hood Canal/West Puget Sound, WA
This project will restore nearshore and delta processes in Twanoh State Park in southern Hood Canal. Washington State Parks (WSP), the primary project sponsor, is working in cooperation with Wild Fish Conservancy (WFC), the project co-sponsor, to develop designs for implementing some of the restoration actions identified in the PSNERP Conceptual Design Report for this site. During the first phase of project implementation, these actions may include: the removal of shoreline fill, rock armoring, and a concrete bulkhead; installation of soft shore armoring; beach nourishment; culvert replacement; large wood placement; and marine riparian planting. Future phases of the project may include movement or realignment of existing parking areas and the installation of an elevated boat ramp pending approval within State Parks management and funding availability.
Washington State Parks has contracted Wild Fish Conservancy to develop engineering designs and specifications for a suite of restoration activities along the marine shoreline in Twanoh State Park and in lower Twanoh Creek. Project designs will be completed by June of 2013, with anticipated construction in 2014. Wild Fish Conservancy will complete conceptual designs for all of the proposed restoration actions. State Parks, working in conjunction with WFC, will then select the project elements that best restore ecological functions and processes while maintaining important park infrastructure, shellfish resources, and historic elements.
Goals & Objectives:
The objective of this project is to restore the physical processes that created and maintained the historic shore forms present at the site to the extent possible. The primary ecological processes our project will address include sediment transport, erosion and accretion of sediments, detritus recruitment and retention, and tidal channel formation and maintenance.
Primary Habitats Impacted By Project:
Twanoh State Park beach & Twanoh Creek - Habitat gain and improvement for chum salmon, coho salmon, Chinook salmon, cutthroat trout, and surf smelt.
