The Kitsap County Department of Public Works (the County) is working with Washington Department of Fish and Wildlife (WDFW) to restore the Harper Estuary.

The project has two phases:

Phase 2 portion of the project design was completed in June 2017. This phase of work is being managed by Kitsap County Department of Public works, Project Manager, Gunnar Fridriksson, 360.337.5777

Project components for Phase 2:
1) Removing the existing 36-inch diameter culvert and associated road fill that exists where Olympiad Drive crosses Harper Estuary with a 120 foot bridge.
A wave pattern for the wall design was selected. Click here to view.
2) ADA compliant beach access path

The goal of the project is to restore tidal influences and natural habitat that are now impacted by the ineffective culverts on Olympiad Drive. The County is the design lead for the culvert replacement and beach access path.

Project schedule:

The Bridge design, including plans and specifications, has been completed by Otak Inc. The project is currently seeking funding. Bridge construction will follow once funding is secured. No date for construction has been set.

The design portion of this portion of the project is approximately $1 million dollars and has been paid for partially by the Asarco funds received in Phase 1 and a grant from the Salmon Recovery Board. Construction for the remaining project components is estimated to be $4.8 million.

This project is on the 2019 Transportation Improvement Program #25

Total project cost for Phase 1 and Phase 2 is estimated to be $8.5 million.
