Mid-Puget Sound Fisheries Enhancement Group used this funding to analyze and develop design plans and permits needed to replace a culvert in Harper Estuary. Harper Estuary is a pocket estuary containing mostly salt marsh and intertidal mudflat, with one main channel and a disconnected fresh water wetland. At time of grant application, Harper Estuary provided little habitat for migrating juvenile salmon due to an existing 36" culvert periodic barrier that caused high ebb tide velocities and to very little habitat within the main channel of flow. Restoration opportunities in the estuary include improving the hydrologic function, geomorphic composition, and specific habitat found in the estuary. The feasibility and design developed in this project built upon an Army Corps of Engineers study (Harper Estuary Section 206 Restoration) and incorporated analysis of both upstream and downstream habitat. Engineering studies determined gradient, drainage, flows, and bank full width. A feasibility study conducted geomorphic analysis important to determine bed load for road and culvert design. This project completed a final design and acquisition of permits. Feasibility assessment included county input on future road improvements, and tribal collaboration in identifying culturally sensitive areas in or adjacent to project premises.
