Harper Estuary Restoration Final Design
The proposed project will complete final designs for a road crossing located within Harper Estuary, a pocket estuary in the vicinity of the Harper-Southworth area on the west shores of central Puget Sound. Kitsap County proposes to complete final design for a bridge to replace an undersized culvert under Olympiad Drive, a road crossing intersecting Harper Estuary. The overall goal of this project is to complete a final bridge design that will allow optimal tidal inundation to the south of the estuary and restore ecological functions of the estuarine area. Pocket estuaries are documented to be a vital element in the life cycle of juvenile salmonids including Chum, Coho, and Chinook salmon for rearing, feeding, and protection from predators.
The Washington DOE received funds from the ASARCO settlement for natural resource damage to restore Harper Estuary. The WA Department of Fish and Wildlife is leading the estuary restoration/cleanup component of the project while Kitsap County is leading the design and construction of a bridge to replace the undersized culvert under SE Olympiad Drive. A Type, Size, and Location (TS&L) Report is attached in PRISM. The final designs will align to Manual 18 Appendix D-3, as well as adhere to Kitsap County road standards, and meet WA State Department of Transportation bridge design manual (as adopted by Kitsap County).
